Answer:
The body parts are arranged like spokes on a wheel
Explanation:
Bilateral symmetry is when it is as two halves. And the other two options are not types of symmetries.
Answer: the expression of certain genes is affected by temperature
Explanation:
For organisms to survive changing environmental conditions, a lot of molecular processes occur in the genes.
For the arctic fox, enzymes coded by specific genes are periodically "switched on or off" depending on the temperature.
Thus, the change in colour can be EXPLAINED by the expression of certain genes affected by temperature
The study of one type of evidence of evolution is called embryology, the study of embryos. An embryo is an unborn (or unhatched) animal or human young in its earliest phases. Embryos of many different kinds of animals: mammals, birds, reptiles, fish, etc. look very similar and it is often difficult to tell them apart.
Answer:
The most common interaction between alleles is a dominant/recessive relationship. An allele of a gene is said to be dominant when it effectively overrules the other (recessive) allele. Eye colour and blood groups are both examples of dominant/recessive gene relationships.
The main difference between dominant and recessive trait is that dominant genes always passes the dominant behavior genes while the recessive ones pass the recessive behavior genes. In fact, the dominant genes are said to be more likely to pass to future generations, while the recessive ones are less likely to do that.
Explanation:
Answer:
Studies revealed that glucose binds with the RBC membrane and intracellular proteins and increases membrane rigidity. The thing is that the concentration of glucose in the solution used is less than compared to the concentration of the same inside RBC and the cells swell up due to endometriosis.
