A) The different cells in an organism have different genes.
B) Each cell transcribes (reads) only the genes the cells need
C) The different cells in an organism all transcribe (read) the same genes, but their ribosomes make different proteins from them.
D) Each cell in an organism produces the same proteins, but the ones that aren't needed are immediately digested.
Answer:
C
Explanation:
The different cells in an organism all transcribe (read) the same genes, but their ribosomes make different proteins from them.
Look again at the enzyme diagram and it’s target molecule. How might a mutation affect the interaction between the enzyme and its target and the function of the enzyme in the organism?
By viewing the enzyme diagram and its target molecule, we can infer that a mutation might affect the interaction between the enzyme and target because it may change the shape of the enzyme and consequently inhibit its function.
What is a genetic mutation?A genetic mutation can be defined as a permanent alteration in the DNA sequence that makes up a gene, which affects the production of a protein and may have a wide range of effects on the function of a cell.
Therefore, with this data, we can see that a genetic mutation may modify the protein and thus affect the reaction.

what 2 parts of a chlorplast does photosynthesis take place
Answer:
The Grana and The Stroma.
Explanation:
I hope this helps u! :D
Answer: Photosynthesis occurs in geranium and stroma parts of chloroplast.
Explanation:
Chloroplast is an organelle covered by double membrane. Inner membrane is folded inside to form lamellae. The lamellae are stacked one above the other to from geranium. There are many grana in a single chloroplast. The remaining matrix consisting of cytoplasm is termed stroma. In the stroma are present other cytoplasmic inclusions like fragments of DNA and ribosome, etc.
Photosynthesis occurs in 2 steps:
1. Hill's reaction or Light reaction: It occurs in presence of light in geranium part of chloroplast.
2. Dark reaction or Blackmann's reaction: It does not require light directly, occurring irrespective of presence or absence of light. However, it is dependent upon the end products of light reaction. it occurs in stroma part of chloroplast.
The answer may be supplemented by viewing the diagram of electron microscopic structure of chloroplast from any book one may have, covering photosynthesis.

Explanation:
What process is the driving force behind evolution?
Answer:
Mutations and natural selection are the main ones
Explanation:
The process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.
What is the significance of natural selection over time?Natural selection is important for the survival of organisms as it is a process by which populations of organisms change over time in response to the outer environment. It is also an important evolutionary mechanism because natural selection always chooses the fittest and natural selection also drives the development of new species and helps ensure the survival of existing species.
Hence, the process that is the driving force of evolution is natural selection, as natural selection is the phenomenon that explains that nature selects organisms over time to survive in ecosystems.

What happens to the cell’s genetic information during the cell cycle?
Answer:I think During most of a cell's life cycle, DNA, along with proteins, is a mass of loose strands called chromatin (KROH-muh-tin). Before cell divion, DNA is duplicated, or copied. Then, in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes (KROH-muh-sohmz).Mitosis is used to produce daughter cells that are genetically identical to the parent cells. The cell copies - or 'replicates' - its chromosomes, and then splits the copied chromosomes equally to make sure that each daughter cell has a full set.During interphase, the cell obtains nutrients, and duplicates (copies) its chromatids (genetic material). The genetic material or chromatids are located in the nucleus of the cell and are made of the molecule DNA. hope this helps have a nice night ❤️❤️❤️

suggest why a baby born without any mitochondria will have difficulties growing
Answer:
or our bodies the conversion from food energy to ATP happens in mitochondria. If your mitochondria are not working properly then you are less able to convert food into ATP. For cells that require a lot of ATP, for example your muscles, this is a problem and they may become weaker and get tired faster.

From the original number of 10 gorillas, there are now 9 gorillas in this population. The correct option is B. After 4 females emigrated, 2 immigrated, 2 gorillas were borned, and 1 male died, there are 9 gorilas.
Available data:10 gorillas in the original group4 females emigrate2 females immigrate2 gorillas are born1 gorilla dies.
So, from the original group, 4 individuals left, so
10 - 4 = 6 individuals
To the group of 6 gorillas, 2 individuals were added, so
6 + 2 = 8
In the group of 8 gorillas, 2 babies are borned,
8 + 2 = 10
And one individual died,
10 - 1 = 9.
The remaining number of individuals in this population is 9. Option B
