which is responsible for genetic diversity.
Answers
Answer: Crossing over
Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️
The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.
What is Crossing over?Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.
Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.
Therefore, the correct option is B.

d) joins one specific amino acid
Answers
Answer:
A transfer RNA (abbreviated tRNA and formerly referred to as sRNA, for soluble RNA) is an adaptor molecule composed of RNA, typically 76 to 90 nucleotides in length (in eukaryotes), that serves as the physical link between the mRNA and the amino acid sequence of proteins. Transfer RNA (tRNA) does this by carrying an amino acid to the protein

Answers
Animals of the same general body types having the same anatomy is True.
Anatomy is the study of the body parts, structures and functions of
organisms.
In situations where animals have the same general body type , then it means
they also have the same anatomy. A good example is mammals which have
the same structure of body parts and the same anatomy.
Organisms with different body structures however have an entirely different
anatomy which is why True is the most appropriate choice.

Answers
Answer:
The biosphere is influenced by other spheres and also influences other spheres.
The biosphere comes into contact with several other spheres such as the hydrosphere, the lithosphere, and the atmosphere.
Contact with the atmosphere is a two way street since the biosphere can alter the composition of the atmosphere. However, many members of the biosphere like mammals and birds depend on the mix of gases in the atmosphere to survive, and weather is an important agent of change.
The lithosphere is another sphere that can impact the biosphere through geologic activity both underground and on the surface. The impact of the biosphere on the lithosphere can be observed through the altering and transformation of terrains and through biochemical weathering of rocks.

Soma- in Latin, means (Body),
So, Somatic cell .. means a Body cell,
Generally, our body contains 2 types of cells according to number of chromosomes :
1- Somatic cells : - almost all body cells are somatic cells
- contain 46 chromosomes (diploid)
2- Germ cells : - only sperms in male & Eggs in female, are germ cells
- they contain 23 chromosomes (haploid)
- they are supposed to unite together (Egg & sperm) to form a diploid cell (23+23=46) ...that will eventually grow into a baby.
