Classify the given terms or examples with the appropriate category
Inner ear cells detecting head position
Skin receptors detecting clothing
Respond to change
Respond continuously
Sensitivity remains constant
Sensitivity decreases over time
Nociceptors continually detecting pain
Answer:
The cells of the ear detect these the position of the head: proprioceptors are guided in the hydrostative pressure and the movement of the intracochlear fluid with the movement. That is why it complies with the following statements: Sensitivity remains constant, Responds to change (we say that it responds to change because when changing position the intracochlear fluid is where the movement of the head is perceived).
The proprioceptors of the epithelial cells (MERKEL CELLS. THEY ARE THE ONLY SENSORY CELLS TOGETHER WITH THOSE OF LANGERHANS), are proprioceptors that capture different textile textures that contact the skin. But throughout our lives this sensitivity decreases, that is why it complies with the following statements: Responds continuously, Sensitivity decreases over time, nociceptors continuously detect pain (to be able to perceive if the innate protective barrier that is epithelial continuity is damaged, since in the face of damage or discontinuity due to a cut or injury we are unprotected by the innate epithelial defense barrier).
Explanation:
I hope the answer has served you, the body's proprioceptors are everywhere and are receptors specialized in capturing very fine stimuli, that is why they are considered proprioceptors with a very low uptake threshold.
The textural propipceptors that are epithelial, or pain, are different from those found in the ear.

Rank each of the following uterine changes associated with the menstrual cycle in chronological order using #1 to identify the earliest event.
A. The endometrium thickens due to secretion and fluid accumulation.
B. Menstrual fluid in the uterus accumulates and is discharged.
C. Due to a degeneration of the corpus luteum, the lack of progesterone causes the endometrium to begin to degenerate.
D. The endometrium begins to thicken due to rapid cell division.
Answer:
#1 The endometrium begins to thicken due to rapid cell division.
#2 The endometrium thickens due to secretion and fluid accumulation.
#3 Due to a degeneration of the corpus luteum, the lack of progesterone causes
#4 Menstrual fluid in the uterus accumulates and is discharged.
Explanation:
menstrual cycles is divided into two phases the follicular and luteal phases, each phase takes about 14 days to complete its cycle. At the follicular phase, the lining of the uterus
called the endometrium breaks down and shed as menstrual bleeding. After the follicular phase there is an increase in hormonal level of follicle stimulating hormone and Lutenizing hormone this leads to ovulation and the rupture and release of the egg follicle in the ovary.
luteal phase involves the formation of corpus luteum where the egg ruptures for a new cycle to start.
What accounts for the difference in the functions and properties of molecules like starches, glycogen, cellulose, and chitin?
Answer:
The difference in function and properties of polysaccharides such as starch, glycogen, celluose and chitin is due to the differences in their recurring monosaccharide units, the types of bonds linking these units and the degree of branching in the molecules.
Explanation:
Polysaccharides are large molecules of carbohydrates which are made up of recurring monosaccharide units. Examples of polysaccharides are starch, cellulose, glycogen and chitin. Each of these polysacccharides show differences in structure, properties and function. The difference in function and properties of polysaccharides such as starch, glycogen, celluose and chitin is due to the differences in their recurring monosaccharide units, the types of bonds linking these units and the degree of branching in the molecules.
Starch is the storage carbohydrate in plants and is composed of two types of glucose polymers, amylose and amylopectin. Amylose is composed of unbranched chains of D-glucose units linked to each other by (α1→4) glycosidic bonds. Amylopectin is a branched glucose polymer linked to each other by (α1→4) glycosidic bonds and (α1→6) at the branching points.
Glycogen is the storage polysaccharide in animals which is highly branched and compact. It is composed of (α1→4) linked glucose subunits with (α1→6) at the branching points.
Cellulose is a fibrous, tough and water-insoluble substance found in plant cellwalls. It is is a linear unbranched polysaccharide made up of D-glucose units linked together by (β1→4) glycosidic bonds.
Chitin is is the main component of the exoskeletons of athropods. It is a linear molecule composed of N-acetylglucosamine units linked together by (β1→4) glycosidic bonds.
In sheep, white is due to a dominant gene (W), black to its recessive allele (w). A white ewe mated to a white ram produces a black lamb. If they produce another offspring, could it be white? If so, what are the chances of it being white? List the genotypes of all animals mentioned in this problem.
Answer:
Yes, 75%
Explanation:
Since the first offspring produced between the ram and the ewe was black you can determine that both sheep have a recessive and dominant allele. Both of the parent's genotypes would be Ww, this is because they both have the white phenotype and they were able to produce a black offspring. Since both parents have a genotype of Ww the probability of a black offspring being produced is 25% and 75% for a white lamb.

Answer:
S.A for Edmentum and Plato
Like and Rate!!!
Explanation:
The interactions and long-term effects of these interactions between organisms and their environments are what lead to evolution and variety. The variety of settings that exist encourages a diversity of creatures that are adapted to them.
What Evolution explains why Earth can support life?The term "evolution" describes the gradual emergence of new traits within a population. This contributes to the explanation of diversity since novel traits might result in the emergence of totally new species and populations.
Darwin argued that species can evolve through time, that new species develop from older ones, and that all species descended from a single progenitor. Organisms are constantly adapting to their environments.
Therefore, In this theory, each species has its own distinct set of heritable (genetic) differences from the common ancestor, which have been slowly building up over very long periods of time.

Kinases and phosphatases are essential in the cell because they directly Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status. destroy IP3, turning off that signaling pathway. bind hydrophobic hormones in the cytoplasm. bind and release calcium ions. activate and repress genes.
Answer:
The correct answers is "turn proteins "on and off" through changes in phosphorylation status".
Explanation:
Kinases and phosphatases are two type of enzymes that catalyze the transference of phosphate groups, where kinases add phosphate groups and phosphatases cleave them. Both are essential because turn proteins "on and off" through changes in the aforementioned phosphorylation status. Most of the phosphorylation are reversible, and they are considered as allosteric regulation
Kinase is an enzyme responsible for attaching phosphate groups to protein while phosphatases remove the attached phosphate group from the protein.
These two enzymes modulate the activity of a protein in a cell which is very important for cell functioning and communications.
The correct answer is:
Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status.
The reason for the answer is:
Phosphorylase and kinase are the enzymes that catalyze the transfer of phosphate groups to the proteins.Kinases are responsible for adding phosphate groups while phosphatase cleaves them. They are antagonistic.They take part in the phosphorylation process of protein and are reversible.They regulate the working of protein by switching on and off with the help of these enzymes.Therefore, Kinases and phosphatases are essential in the cell because they directly turn proteins "on and off" through changes in phosphorylation status.

1. Simple columnar and pseudostratified columnar epithelium both are considered simple epithelium that consist of column-shaped cells.
A. True
B. False
B. Simple columnar cells line up next to each other whereas there is an irregular arrangement with cells varying in height and shape in pseudostratified columnar epithelium, giving the impression of stratification.
A. True
B. False
Answer:
Both options are true.
Explanation:
The cylindrical epithelium is a simple epithelium, which is characterized by having a cell layer, where all the cells are supported on the basement membrane, and its nucleus has reverse polarization in relation to the rest of the cells of our body, that is, they are found in a not very common position.
Simple cylindrical epithelia are found in areas of absorption or assimilation and exchange of gases or nutrients, since this shape is what allows them optimal diffusion through the epithelium, an example of the tissues in which this cellular architecture is found. They are the intestinal tract and the respiratory tract.
In the case of pseudostratified epithelium, it is very similar in function to the cylindrical one, with the difference that it gives a multilayered appearance, that is, its cells are stacked one from the other, giving the appearance of more than one epithelial layer as the stratified epithelium of our epithelial organ, but nevertheless it is not like that, there are many cells of irregular shape with a support in the basal one, that is why it is a single layer.
This last epithelium is also found in the airways in large numbers.

2. Compare and contrast the three basic types of experiments. Provide an example of each one to support your statements.
Part 2: Read the passage carefully and then answer the following question.
Researchers at a major university are testing a new drug to lower cholesterol, called Choless. They started the study by testing mice. Once they received the proper FDA clearances, they began trials on humans. They began testing on males, whose ages ranged between 30 and 60 years old. The researchers split the participants into two groups. Group A was given Choless, while Group B was given placebos. A placebo is completely harmless and looks exactly like Choless, but it contains no active medicine. None of the participants knew whether they were taking Choless or the placebo. The participants were to eat a diet low in saturated fats, and high in protein and fiber. Each participant's cholesterol levels were tested and recorded every week.

What term is used to describe 100’s or 1000’s of amino acids chemically combined?
Answer:
Polypeptide
Explanation:
Amino acids are the building block and simplest unit of protein molecules. The structural composition of each amino acids is made up of an amine group (-NH2), a carboxylic acid group (-COOH), a hydrogen atom (H) and a R side chain that differentiates every amino acid from one another.
In a reaction process called condensation, amino acids are chemically joined together via the amine group of one and the carboxylic group of another. This process releases water molecule (H20) to form a bond called PEPTIDE bond between the amino acids. Several amino acids in their 100’s or 1000’s that are chemically joined this way forms a POLYPEPTIDE chain, which in turn forms the protein molecule.

What are the characteristics of species?In biology, a species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction.
If the offspring cannot breed and produce offspring, then the original two organisms are classified as different species. For example, a donkey and a horse are different species, but they are capable of mating and reproducing an organism.
The classification system commonly used today is based on the Linnean system and has eight levels of taxa; from the most general to the most specific, these are domain, kingdom, phylum (plural, phyla), class, order, family, genus (plural, genera), and species.

You water three sunflower plant with salt water. Each plant receives a different concentration of salt solutions . A fourth receives pure water. After a two -week period, the height is measured . What is the independent, dependent and controlled variable.
Answer:
Independent - Water/Type of water (salt and pure)
Dependent - Height of plant
Controlled - Amount of water
Explanation:
Independent is what the experimenter manipulates (in this case being the type of water.)
Dependent is what the experimenter measures and is a result of the independent (in this case being the height of plant)
Controlled is what you are trying to keep the same (in this case the amount of water you give each plant.)
In the experiment given, the independent variable is the salt water, the dependent variable is the height of each plant, and the sunflowers are the control variable.
Variables in an experiment can be one of three kinds:
Control Dependent IndependentThe dependent variable is the variable that will change based on the other variables, this is often what the experiment seeks to measure. In the case given, the variable that will be measured is the height of the plants, therefore this is the dependent variable.
The independent variable is one that will not depend on the other variables in the experiment. Since the salt water used for each plant does not depend on the kind of plant or on its height, we can infer that the salt water is the independent variable of this experiment.
The control variable is the variable that remains constant in an experiment in order to not affect the outcome. Since for each case in this experiment there is no difference in the kind of plant that is used, we can say that the sunflower plant is the control variable.

Which choice best summarizes the outcome of Reid’s experiment
This question seems to be incomplete because the experiment is not described but it is possible to answer it.
The correct answer is B. Redi disproved spontaneous generation.
Explanation:
Francesco Redi was an important scientist during the 17th century known for his experiments about maggots in rotten meat. This is because during Redi's time it was believed rotten meat was the origin of maggots because maggots seemed to emerge from this. Additionally, this perception was related to the spontaneous generation or the idea life can emerge from non-living materials. The results of this experiment show the idea about spontaneous generation was not true in the case of meat and maggots because maggots were simply the result of eggs flies laid on rotten meat. This means this experiment disproved spontaneous generation.
