Answer:

The likelihood that their offspring will roam with both colors represented is of 100%.

Explanation:

The exposed example brings up the case of a codominance example. When the hair color of horses is codominant, roan coats occur. Roan horses express both the colored and the whited hairs, with some of the animal´s parts expressing mostly the colored hairs, such as head, tail, and legs. These animals have white hair and another solid color (such as black). When two purebred animals with different genotypes and phenotypes are crossed, the whole offspring will be heterozygous.  In this case,  a purebred white horse C^w and purebred black horse C^B are bred together. The offspring will carry the heterozygous genotype C^wC^B. The offspring will have both red and white hairs.

In codominance, both alleles can be expressed. In these cases, heterozygote individuals instead of showing an intermediate phenotype, express both of the alleles (red and white hair). Their phenotype is an additive expression of their parents' genes.

Answer:

1. d

Explanation:

The correct answer would be that the system of peer review is used to determine conclusively the conclusions of the paper.

The system of peer review refers to the process of evaluating a scientific report or paper by one or more independent scientists who have a similar background as the producer of the report or paper.

The reviewers evaluate the methodologies and various claims made by the original researcher and give feedback on their validity as well as make criticism of the paper in order to improve its quality before final publication. However, reviewers do not alter the claims or conclusions of papers, they can only query them.

Hence, options a, b, and c are correct as far as the peer review system is concerned.

The only incorrect option here is d.

2. There are 3 types of experiments, namely:

The controlled experiment involves the comparison of experimental group with control group. The two groups are subjected to the same conditions except for the variable whose effects are being researched.

The field experiment takes place outside the laboratory settings as opposed to other types of experiments. The subjects of the field experiment are studied in their natural environment outside the lab.

The natural experiment involves studying a phenomenon naturally without having control, unlike the controlled experiment. Observations are just recorded and are used to arrive at predictions or hypotheses.

Part 2:

Subject: 30 - 60 years old males

Control: Group B, the placebo group

Constant: Diet.

Independent variable: Administered drugs (choless and placebo)

Dependent variable: cholesterol level.

Part 3

Experiment 1:

a. Independent variable: types of detergent

b. dependent variable: height of foam

c.  constant variables: amount of water, container type, temperature, period of agitation.

Experiment 2:

a. independent variable: amount of weight in each car

b. dependent variable: amount of gasoline left in each car

c. constant variable: car, type of gas, speed of car, distance covered by car.

Experiment 3

a. independent variable: amount of light

b. dependent variable: number of remnant bacterial cells after exposure to light

c. constant variable: initial number of bacteria, petri dish, type/amount of growth medium.

Experiment 4

a. independent variable: level of salinity

b. dependent variable: biomass of plant

c. constant variable: type of plant, period of growth, growth conditions.

Answer:

D. All of above

Explanation:

This is because we can add temperature as a variable to improve the light, pH as a variable to improve the water, and remove water or light as a variable to make the experiment on light or water even obvious.

Answer:

Discover the volume of a balloon.

Explanation:

Get a balloon and a piece of paper. Cut the paper to make a line, and make sure it is 100 cm x 2 cm Take on of the balloons and inflate it several times so you are sure you can inflate the balloon with only one breath. Take a deep breath and inflate the balloon. Use a binder clip to hold the neck so no air escapes. Make a measurement of the circumference of the balloon using v = c3/6(pie)2 - the formula is c cubed divided by 6 times pie squared equals volume.

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.

Answer:

Scenario B is more likely to have been peer-reviewed because it was published in a scholarly journal (Professional Journal of Medicine).

Explanation:

A peer-reviewed article is an article that has undergone review by experts in the same field as the author in order to ascertain how original and quality-oriented the article is before publication in a journal. The experts from the same research field as an author are the "PEERS". A successful peer-reviewed article is deemed to be of high quality.

Although there are many features an article must possess in order to know it has been peer-reviewed but one of the most important features is that the article will be published in a REPUTABLE SCHOLARLY JOURNAL. This is the case of the article in scenario B, which was published in the Professional Journal of Medicine not just any non-academic random magazine as in scenario A.

Answer: The article that Cicely read (Scenario B) has been peer reviewed. This article is published in a scientific journal and has been judged for quality by other professionals in the field.

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.

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.

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:

The 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.

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.

Worldwide health issues are complex real-world problems because this problems are usually caused by diseases, pests, vectors and poor hygiene. All the factors listed vary according to geographical and economic conditions. Hygiene is good and better in first world countries such as USA and very poor in Third World countries.

Pests and diseases are also sometimes peculiar to a certain area which makes the issue of solving world health issues a very complex one as a result of it not being universal most of the time.

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.

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.

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.
