Answer:

The graphical representation of the age structure is known as age pyramid (option D).

Explanation:

The age pyramid or more properly called population pyramid groups all the individuals of a population, distributing them by age and sex. The name is due to the fact that, in general, the bar graph resembles a pyramid.

The age groups are distributed in the pyramid by age from lowest (bottom) to highest (top), with the sexes forming the sides of the pyramid.

In emerging countries the population is relatively young, which makes the base of the pyramid wide, narrowing as it moves up to the upper age groups.

    Age group, age graph or age scale do not correspond to the population graph where the age and sex structure of a population are expressed.

Contour type of feather gives the bird its color. Therefore, the correct option is C.

The outer feathers that give a bird its color and general appearance are known as contour feathers. The barbs on the branches that make up the central shaft of these feathers join to form a strong, streamlined structure. The barbs have their own little branches, known as barbules, which contain pigments that help give the bird its color.

The diverse colors and patterns seen on many bird species are determined by the arrangement and color of pigments in the barbules of contour feathers. Therefore, contour feathers are important in determining a bird's color.

Therefore, the correct option is C.

Blood type is an example of  ✔ codominance

Explanation:

Blood type is determined by the  ✔ antigens  on the blood cells.

✔ Antibodies  attack foreign blood that does not contain the same antigens.

Blood type is an illustration of codominance.

Blood group also known as blood type refers to classification of blood on the basis of the absence and presence of antibodies and inherited antigenic components on the red blood cells surface. These antigens may be:

The blood type in humans is an example of codominance. In codominance, neither of the allele can inhibit the expression of the other allele. One of the example is the ABO blood group in humans. In this, both the alleles A and  B are expressed.

Therefore, if a person is inheriting allele A from the mother and allele B from the father, he or she will have the blood type AB.

Thus, blood type is an example of codominance.

Explanation:

sister chromatids

Answer:

This question is incomplete, however, it is asking to identify the following variables:

Independent variable: Temperature

Dependent variable: Number of yeast cells

Constants: same amount of nutrients, same number of yeast cells, same medium

Explanation:

- Independent variable is the variable that the experimenter changes or manipulates in order to bring about a measurable effect. In this experiment, the TEMPERATURE at which the yeast are kept is the independent variable.

- Dependent variable is the variable that responds to the changes made to the independent variable. It is the variable that is measured by the experimenter in the experiment. In this case, The NUMBER OF YEAST CELLS was counted, hence, it is the dependent variable.

- Constants are variables that are kept unchanged or same for all groups by the experimenter in order not to influence the experiment's outcome. In this case, the CONSTANTS are: same amount of nutrients, same number of yeast cells, same medium etc.

Answer:

D. A sample of distilled water

Explanation:

You need to have a control sample that hasn't been messed with to see what would happen if you had no reaction to your experiment

A sample is the smaller set of data which a researcher makes use of to complete a research.

As a result of this, we can see that a sample study is the use of these samples to come to a conclusion about the investigation or research which is going on.

Some examples of a sample study include:

The cell theory states that:

a) all living organisms are made up of cells

b) cells are the basic structural and organizational unit of life

c) all cells arise from pre-existing cells.

From the three statements above, all living organisms fall into the categories hence from the list, all the living organisms (Kitten, mushroom, bacteria, and cactus) are made up of cells. While rocks are non-living hence they are not made up of cells.

Answer:

The correct answer is -

Phenotype: 3:1 (dominant black mice: recessive brown allele)

genotype: 1:2:1 (purebred dominant : heterozygous: purebred recessive)

Explanation:

In the given question there is a cross that takes place between two heterozygous black mice. LEt assumes B is black which is the dominant allele and b is the recessive allele or brown. As it is given in heterozygous condition black mice are present which means the B is dominant over b.

Now cross:

Gametes: B and b for each mice

      B        b

B     BB      Bb

b    Bb       bb

By the cross, there are two phenotypic offspring that produce 3 black mice out of four and 1 brown or recessive allele out of four

And, genotypically three offspring in the ratio of 1:2:1 (purebred dominant : heterozygous: purebred recessive)

Answer:

Phenotype: 3 black mice: 1 brown mice

Genotype: 1 BB: 2Bb: 1bb

Explanation:

This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.

If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:

BB, Bb, Bb, and bb

- The phenotypes of this cross is  3 black mice: 1 brown mice

- The genotypes of the cross is 1 BB: 2Bb: 1bb
