a. Position of geese flying in V formation
b. Color and shape camouflage of praying mantis
c. Muscle atrophy in aging dogs
d. Male dominance in a pack of wolves
The color and shape camouflage of praying mantises is an example of an heritable trait possessed by an animal that will improve its reproductive ability and survivability in its environment. So, the correct option is (B).
What are Traits?A phenotypic trait is defined as a specific type of a phenotypic characteristic of an organism that can be either inherited or environmentally determined, but usually occurs as a combination of both.
These are characteristics or features of an organism that are expressed by genes and/or influenced by the environment including physical properties of the organism such as hair color, leaf shape, size, etc., and behavioral characteristics such as bird nests.
The color and shape camouflage of praying mantises is an example of an heritable trait. Thus, the correct option is (B).

What is the role of microfilaments in cell division?
Answer:
to help divide the cell during mitosis/ aid the process of cytokinesis
Explanation:
Answer:
microfilaments are made up of proteins including actin and myosin
these proteins help "pinch off" the two daughter cells during cell division during the final stages, a microfilament ring forms and contracts to separate the new cells during cytokinesis.

Need help plz!!! Trying to catch up on biology anything can help!!!!
Answer:
See the answer below
Explanation:
The control group in an experimental study is the subject group that is not administered the treatment variable. The control group forms the baseline for comparing the effects produced by the treatment variable on the experimental group.
Thus, in this case, the control group would be the 10 mice that were not exposed to the radio waves.
The independent or the manipulated variable, in this case, is the exposure or otherwise of the mice to the radio waves.
The dependent variable is the actual variable that is going to be measured, otherwise known as the effect variable. In this case, the dependent variable would be the strength of the mice measured by their ability to push the block of wood blocking their food.
Since 8 out 10 mice and 7 out of 10 mice were able to push the wooden block in both the experimental and the control group, Bart's conclusion should reject the hypothesis that the radio waves make mice extra strong.
Bart's experiment can be improved by increasing the number of subject mice in each group. The more the number of subjects, the more the accuracy of the outcome would be.
Use the following questions to write your conclusion to your lab report.

Explanation:
In a plant species, the allele for dark green leaves (D) is dominant over the allele for light green leaves (d). A plant with Genotype (Dd) is crossed with a plant with genotype (did). What percentage of the offspring are expected to be hybrid for the leaf color trait. A 0% B 25%. C.50%. D 75%
The percentage of the offspring that is expected to be hybrid for the leaf color trait is 50%. The correct option is C.
What are alleles?The trait is caused by a pair of two alleles on the chromosome, and there are two possible outcomes. The dominant allele, which is typically written in capital letters and will control the organism's phenotype even in the presence of the other allele, is the one that has the ability to silence the other allele.
It is used in biology to refer to inherited traits that do not manifest in the phenotype of the individual who possesses them but may do so in their offspring.
Recessive alleles, which are only expressed when they are homozygous, are this other type of allele. Both heterozygous and homozygous genotypes exhibit the dominant allele.
Dd is crossed by dd.
100 / 2 = 50%.
Therefore, the correct option is C.

In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).
