Answer:
Any even number, becuase their sex cells will need half as many, this will not work with an odd number.
Hope this helps :)
In sexual reproduction, the chromosome number of a species is determined by the number of chromosomes present in its body cells. Through the process of meiosis, gametes with half the original chromosome number are produced. When fertilization occurs, the diploid chromosome number is restored in the offspring.
In sexual reproduction, the chromosome number of a species is determined by the number of chromosomes present in the cells of its body. This is referred to as the diploid number. During sexual reproduction, gametes (sperm and egg cells) are formed through a process called meiosis, which reduces the chromosome number in half. When the sperm and egg combine during fertilization, the chromosome number is restored to the diploid number in the offspring.
For example, humans have a diploid chromosome number of 46. During meiosis, each parent will produce gametes with a haploid chromosome number of 23. When fertilization occurs, the sperm and egg combine to form a zygote with a diploid chromosome number of 46.
Other species may have different diploid chromosome numbers. For instance, the diploid chromosome number for fruit flies is 8, for dogs it is 78, and for corn it is 20. These numbers are specific to each species and are determined by their genetic makeup.

Answer:
Shape and size vary from cell to cell according to their functions and composition. For example, a nerve cell is long and branched, meant for the transmission of signals throughout our body while a muscle cell is small and spindle-shaped which helps in movement.
Explanation:
Answer:
A decrease in stability among populations
Explanation: if several species of carnivores are taken away from an ecosystem, there will be an instability among populations. Some of the factors that might cause the decrease in stability are that there would be an over population of the prey animal that would not be eaten by the carnivores and that the plant life would be in danger because of the over population of hervibores.
B. epicenter.
C. hotspot.
D. magnitude.
In this case, the type of character is the A nucleotide at position 45 is - C. Derived.
The derived characters or traits are that arose in the most recent common ancestor and passed on the lineage. It can be referred to as traits that are not present in older ancestors but in recent lineage.
Thus, the type of character is the A nucleotide at position 45 is - C. Derived.

Answer:
Explanation:
Derived kind of character is the A nucleotide at position 45.
Derived character: Derived kind of character is one that evolved in the lineage and leading up to a clade and that sets members of that clade apart from other individuals
Example of a derived character: the loss of a tail, a trait that first appeared in an ancestor of apes and man.
B) enclosed in protein capsule
C) undergo cellular respiration
D) produce proteins in ribosome
Answer:
The correct answer would be B) enclosed in a protein capsule
Almost all living cells contain DNA as their genetic material. DNA control and coordinates the function of the cell. The two cells also must contain the DNA.
Cellular respiration refers to the set of biochemical reactions by which the cell generates ATP or energy. All the living cells produce energy through cellular respiration, however, they may utilize the aerobic or anaerobic form of respiration.
A ribosome is found in all the living cells including animal cells, plants, bacteria et cetera. They form the site for protein synthesis in all the cells.
The protein capsule is not a universal feature of all living cells. Thus, it may be present in one cell type and absent in another cell type.
Answer:
The answer is B) Enclosed in protein capsule.
Explanation:
If you look at all the other options, they are present in all the cell types. Be it a plant cell or an animal cell or bacterial cell, they all contain the genetic material DNA, they undergo or exhibit cellular respiration which is responsible for the release of energy and all the cell types contain ribosomes which is the site of protein synthesis. Only some cell types are enclosed by protein capsule like some viruses but not all cell types, thus the answer is B.
