Answer:
Apes are considered the most closely related organisms to humans because we share so much dna. For example, we share 99% of our DNA with Chimpanzees. On average, human beings share 65% of our dna with other mammals but apes are a much higher percentage, on average in the higher 90's.

Ion pumps and phagocytosis are both examples of
________.
a. endocytosis
b. passive transport
c. active transport
d. facilitated diffusion
Answer:
A
Explanation:
EDGE2021
Ion pumps and phagocytosis are both examples of active transport. Therefore, the correct option is C.
The movement of molecules or ions across the cell membrane against a gradient of concentration, from an area of lower concentration to an area of higher concentration, is called active transport. In this whole process energy must be used in the form of ATP (adenosine triphosphate).
Ion pumps are membrane proteins that actively transport ions across the concentration gradient across the cell membrane. These ions include sodium, potassium, calcium or hydrogen ions. The ion concentration imbalance required for many cellular functions is maintained by these pumps.
On the other hand, phagocytosis is a type of endocytosis in which cells engulf large molecules or solid particles and internalize them. Energy is required for the formation of pseudopods and for the solubilization of substances in the phagosome inside the cell.
Therefore, the correct option is C.

Oil is a renewable energy resource. It is processed to make jet fuel. Thus, the correct option is B.
What are renewable energy resources?Renewable energy is the energy which is derived from natural sources which are replenished at a higher rate than they are being consumed. Sunlight and wind are the two such sources of energy which are constantly being replenished from the planet. Renewable energy sources are present in plentiful amounts and are found all around us.
Jet fuels are the energy fuels which are typically made by the blending and refining of various crude oils such as petroleum distillation products including naphtha, gasoline, or kerosene in order to meet the specific military or commercial specifications required.

Explain how fossil fuels are formed from living organisms on land and in sea.
Petunia flower color is governed by two alleles, but neither allele is truly dominant over the other. Petunias with the genotype R1 R1 are red-flowered, those that are heterozygous (R1 R2 ) are pink, and those with the R2 R2 genotype are white. This is an example of incomplete dominance. (Note that superscripts are used rather than upper- and lowercase letters to describe the alleles).
a. If a white-flowered plant is crossed with a red-flowered plant, what is the genotypic ratio of the F1?b. What is the phenotypic ratio of the F1?c. If two of the F1 offspring were crossed, what phenotypes would appear in the F2?d. What would be the genotypic ratio in the F2 generation?
Answer:
a. 4 R¹R²
b. 4 Pink flowers
c. 1 Red, 2 pink and 1 white phenotypes
d. 1R¹R¹ : 2R¹R² : 1R²R²
Explanation:
This question involves a single gene coding for flower color in petunia plants. However, the allele for red flower color (R¹) is incompletely dominant over the allele for white flower color (R²), hence, a pink intermediate phenotype (R¹R²) is formed.
According to these questions;
A. If a white-flowered plant (R²R²) is crossed with a red-flowered plant (R¹R¹), all of the F1 generation will have a genotype of R¹R² (see attached image for punnet square).
B. The F1 generation, which possess a genotype: R¹R² will express the pink flower phenotype because neither of the two alleles are truly dominant over the other i.e incomplete dominance.
C. If two of the F1 offspring were crossed i.e. R¹R² × R¹R², each parent will produce R¹ and R² gametes. Using these gametes in a punnet square (see attached image), the following phenotypes will be produced in the F2 generation: Red, pink and white phenotypes
D. The F2 generation will possess a genotypic ratio of 1R¹R¹ : 2R¹R² : 1R²R².
Which model represents a DNA molecule?
Answer: The answer is D because the way they line up!!
Explanation:
The model that gives a true representation of a DNA molecule would be the 4th model.
What is the structure of DNA?According to Watson and Crick, the DNA is a double strand molecule with each strand twisting around one another to form a ladder-like, double helix structure.
Also, there is a complementarity of nucleotide bases such that Adenine (A) always pairs with Thymine (T) while Guanine (G) always pairs with Cytosine (C).
Thus, model 4 ticks all the characteristics of a typical DNA molecule.

PLS HELP, Why is gene flow important to the overall health of a species?
Answer:
Gene flow is an important mechanism for transferring genetic diversity among populations. ... Gene flow is expected to be lower in species that have low dispersal or mobility, that occur in fragmented habitats, where there are long distances between populations, and when there are small population sizes.
Explanation:
Answer:
Because it is important for transferring genetic diversity among populations. Even low levels of gene flow can have a large impact, counteracting the other evolutionary force.

The best description of arrangement of the sides of the DNA molecule bonding is; Alternating.
The DNA molecule is made up of of two strands that are wound around one another to form a shape known as a double helix.
The double-helix can be compared to a twisted ladder and is therefore categorised as alternating.
Each strand has a backbone made of alternating sugar (deoxyribose) and phosphate groups.

A population of birds eats nuts and seeds. Some birds have larger beaks, and some have smaller beaks. A pair of birds usually produces four or five offspring each year. After several yeaers of little rain, the seeds became larger and larger. The birds with larger beaks were better at cracking these seeds. After several generations, the average beak size in the population increased. Bird beak size increasing after several generations is: a. decent with modification. b. variation. c. overproduction. d. adaptation
As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

Explanation:
Grasslands typically do not flourish when large herbivores are removed. In fact, they are soon replaced by broad-leaved herbaceous dicots, shrubs, and trees. Based on your knowledge of the structure and growth habits of monocots and eudicots, suggest a reason why.
Answer:
Grasslands and herbivores have a mutually beneficial symbiotic relationship. If larger herbivores such as Kangaroos and Elephants are removed from them, they may become extant.
Explanation:
Herbivores are always hungry and they are always looking for ways to replenish lost energy. Between tree shoots and grass, they often go for the former because they are tender, easier to reach, and less difficult to masticate than the young tree shrubs.
When baby trees become bigger, their shade prevents adequate sunlight from reaching the grass, then gradually they become scanty or subdued for as long as the shade remains.
When large herbivores are removed or leave a grassland, trees have the ability to flourish. Then the results indicated above happens.
