Answer:
A, C, D are true, B is false
Explanation:
Prokaryotic cells are surrounded by a plasma membrane, but they have no internal membrane-bound organelles within their cytoplasm. They have a cell wall and cytoplasm containing ribosomes
Answer:
Major histocompatibility complex (MHC) antigens
Explanation:
The process in which recipient body rejects the transplanted organ is called a allograft rejection or transplantation rejection.
A transplanted organ contains Major histocompatibility complex (MHC) antigens which are required to be accepted by the recipient's body to function properly but T cells in recipient's body become alloreactive and recognize MHC antigens (donor-derived antigens) as foreign and starts making antibodies against it. Which means the recipient's body is rejecting the transplanted organ.
Hence, the correct answer is "Major histocompatibility complex (MHC) antigens".
Answer:
lichen
Explanation:
Common examples of pioneer species include bacteria, lichen, mosses, and fungi.
The answer is the
population size. The chance has a role
in determining whether a given individual survives and reproduces and the
alleles in the offspring are a sample of those in the parents. it is the change
in the frequency of an existing gene variant (allele) in a population due to
random sampling of organisms. Genetic Drift or another term for allelic drift
or the Sewall Wright effect.
Answer: The shape of the skull and the supraorbital height tell us the following about each species-
- It can tell us about the intelligence of species and what all senses they were dependent upon for their survival
- Most of the species possess similar skulls as mostly their structures are oval shaped, sloped or round shaped.
- Species have different food habits that is determined by the teeth, which vary from long and dull to short and dull.
- Variation in teeth and face shapes could also be due to different geological locations.
- In particular, the foramen magnum be located where the spine connects can be attributed to how the species gathered food through hunting and what kind of food they sought after.
- Overall, the shape and the supraorbital height of each skull informs us the advantages and disadvantages each species had in its ecosystem.
- It also tells what probable causes of death would be when the species died.
