Answer:
Option A: True
Explanation:
Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.
As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.

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:
The formation of one isochromosome
Explanation:
In cytogenetics, an isochromosome is a structurally abnormal chromosome that renders two chromosome arms which are identical inverses of each other. An isochromosome is caused by simultaneous duplication and deletion of genetic information during DNA replication. The resulting isochromosome will contain two identical copies of either the long or short chromosome arms that are disposed as a mirror image.

Genetics and Genomics are two terms that are used commonly in molecular biology but mean entirely different things.
Genetics is the study of individual (single) genes and their role in genetic inheritance i.e. heredity while Genomics is the study of all the genetic composition of an individual (genome) and how they interact with one another and their environment.
Based on the explanation above,
- the study of individual gene is classified as GENETICS
- study interactions between many genes is classified as GENOMICS
- study of DNA, which contains all the genes of an individual is classified as GENOMICS
- sequencing the genome of organisms is classified as GENOMICS.
- control of gene expression is classified as GENOMICS because it involves expression of information in the genes, which is a branch of genomics called functional genomics
- observing mutant effects across the genome is classified as GENOMICS
Classify each action as belonging to genetics, genomics, or both.
a. Study individual gene - Genetics
b. Study interactions between many genes - Genomics
c. Study DNA - Both (primarily Genetics)

Explanation:
Select two items that biologists agree are necessary in order to consider an organism “alive.” For each, give an example of a nonliving object that otherwise fits the definition of “alive.”
Answer:
Cellular organization and metabolism are two items necessary to consider an organism alive.
Explanation:
There are certain characteristics that belong to living beings and that they all have in common. These are distinctive characteristics that do not include any non-living object. Among others, we can name the followings:
1) Precise cellular organization. The cellular theory states that every living being is conformed of basic units named cells and their products that result from the cellular activity. Although organisms vary in size and shape, all of them are formed by cells. A cell is the simplest part of the living matter which is capable of performing every necessary activity needed for life. Some of the simplest organisms, such as bacterias or some algae, are unicellular. This unique cell must be polyfunctional, as it has to perform many activities. On the other hand, many other organisms are highly complex pluricellular. All the processes of the entire organism depend on the correct and coordinated functioning of every constituting cell. The more complex the organism is, the more specialized are the cells, differentiating from each other, and acquiring certain specific functions. These are, for example, the epidermic cells, muscular cells, nervous cells, reproductive cells, among others.
2) Metabolism. In any living being there happen many essential chemical reactions needed for appropriate nutrition, growth, cellular repairing, energy conversion, among others. All of these chemical reactions in the organisms are known as metabolism. These cellular activities begin when the organism takes life, and continue through its whole life. When chemical reactions stop, the organisms might be considered to be dead. Every specific cell in the organisms take substances that chemically modify, in many different ways, to integrate new cellular components. Some of these nutrients are used in cellular respiration. During this process, part of the energy stored is taken by the cell for its own use. This energy is also needed for synthesis and other cellular activities. In most organisms, cellular respiration requires oxygen provided by the gas interchange. Cellular wastes, such as carbon dioxide and water must be eliminated from the organism. Every chemical reaction is regulated by specific enzymes.

#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.

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.

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.

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.

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.
