There are basically three types of evolution divergent, convergent and parallel evolution.
a) Divergent Evolution – As the name depicts the species in this form of evolution becomes divergent i.e they evolve to become different from each other. This form of evolution is responsible for the current diversity of organisms existing on planet earth. For example human and apes evolved from a common primate ancestor.
Answer:
a
Explanation:
A. Channel and carrier proteins move substances in a certain direction, regardless of their concentration gradients.
During infection with Listeria, an intracellular bacterium, APCs will present antigen on MHC II molecules and triggers a phagocytic property by stimulating the release of macrophages.
What is the role of macrophages in Phagosomes?
Phagosome maturation was formerly regarded to be a very simple notion that described how much phagosomes had united with lysosomes.
- Unfortunately, this assumption is no longer valid because phagosomes are now known to interact with a variety of intracellular organelles during their maturation process.
- Proteins, such as the NADPH oxidase complex that creates the superoxide burst, may be seen being assembled on the phagocytic cup even before they are fully formed.
- When the phagosome closes and the maturation process begins, it becomes increasingly acidic and hydrolytically active, and it transiently fuses with the recycling endosomal system, the secretory system, including secretory lysosomes, multi-vesicular bodies such as the MHC class II (MIIC) compartment, and even the endoplasmic reticulum.

Answer:
Heterozygous dominant
Explanation:
because, as you know, heterozygous is different, and Dd has both dominant and recessive, making it heterozygous rather than homozygous.
Because the first d is dominant (capital D), then it makes the genotype dominant and heterozygous.
Answer: C)
Explanation:
I am 100% sure, however,
a) It is true that developed countries have lower death rate, but that doesn't contribute to the question and supports the opposite thesis.
b) In developed countries there is less birth rate as we see with demographic crisis in Europe and China.
c) Lower birth rates provides less people for the economy and is the most feasible answer
d) Fake news, there are actually lower death rates in developed countries compared to developing ones.
