Answer: Explanation:
We have two sets of chromosomes because we're diploid organisms: the most obvious function of this is that two parents can mix and match their genes in (figurative) hopes of getting some optimum combination in at least some of their offspring.
Hope this helps!!!!
Each human cell only has 1 set of 23 chromosomes. The only time it gets 2 is when it is about to divide and copies its DNA (go through mitosis and cytokinesis). When the cell splits, each daughter cell will have 1 set of 23 chromosomes again.

A.circulatory system
B.nervous system
C.skeletal system
D.respiratory system
Red blood cells and blood vessels belong to the circulatory system, which is responsible for the transport of nutrients, gases, and waste throughout the body.
In the case of the Tyrannosaurus Rex skeleton found by Bob Harmon and later studied by Dr. Mary Schweitzer, the structures which were found that were identical to modern red blood cells and blood vessels belong to the circulatory system. This system in the body is primarily responsible for the transport of nutrients, gases, and waste throughout the body via the blood, which collectively forms in a network of blood vessels, like veins and arteries, and is pushed through these networks by the heart.

explain it.
A.
worms
B.
frogs
C.
clams
D.
fish
Any of a subphylum (Vertebrata) of chordates consisting of animals (such as mammals, birds, reptiles, amphibians, and fishes) with a bony or cartilaginous spinal column that replaces the notochord.
The vertebrates are frogs and fish.
Thus, we can conclude that Options B and D are correct.

Answer:
Each B cell produces a single species of antibody, each with a unique antigen-binding site
Explanation:
Answer:
B cells produce antibodies
Explanation:
Each B cell produces a different type of antibody
B. Cytoplasm, chloroplasts, and genes
C. Vacuoles, nucleus, and chromosomes
D. Chromosomes, chloroplasts, and vacuoles
The cell components that are most involved in determining the hair color of each sibling is gene, chromosomes, and nucleus. The correct option is A.
Genes are small spherical-shaped hereditary material that is present on chromosomes in a bead fashion. They contain the hereditary material of the organism. These are uncountable numbers of genes present in the chromosome.
Chromosomes are x shapes of hereditary material that are preset inside the nucleus. It is made up of DNA, genes, and proteins. Genetic characteristics of the genotype of an organism are unique because of unique genetic material, and this can be transferred to another generation from the first generation.
Therefore, the correct option is A. Gene, chromosomes, and nucleus.

Answer:
A
Explanation:C and D is automatically eliminated because humans don't have vacuoles (plants do) as well as B because humans don't have chloroplast
b) less than the number of carnivores
c) equal to the number of scavengers
d) none of the above
Answer:
Option D
Explanation:
In a balanced ecosystem, the flow of resource, food and energy must be adequate enough to fulfill the requirement of all.
In case if the population of deer is higher than the population of producers then the producers would not be able to meet out the requirement of herbivore deer. Hence, this option is incorrect
In case if deer population is less than the population of carnivores, all the carnivores will not be able to get sufficient food. Hence, this option is also incorrect
Option C is also not feasible as equal number of scavengers will not be able to degrade the large biomass of dead animals and plants.
Hence, option D is correct
Answer:tHE ANSWER IS d
