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.

Explanation:

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.

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.

Two pieces of information that scientists use to prepare evolutionary trees for living and extinct organisms are the fossil evidence that is found on the earth and the DNA samples, as these two are helpful in the evolutionary tree representation.

An evolutionary tree, or phylogenetic tree, is a diagrammatic representation that shows the relationships between different species or groups and is used to represent the evolutionary history and how organisms are related to one another through common ancestry. The evolutionary tree is important as it helps scientists understand the relationships between different species and how they have evolved over time to form new species.

Hence, two pieces of information that scientists use to prepare evolutionary trees for living and extinct organisms are the fossil evidence that is found on the earth and the DNA samples, as these two are helpful in the evolutionary tree representation.

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.

Note about the question:

Among the (observed-expected)² list, there is one value missing. This value corresponds to round yellow gray plants, and equals 0.002. This number was included in the explanation of the problem.

Answer:

The chi-square value is X² = 2.6813.

Explanation:

Available information:

Observed individuals numbers:

The expected numbers

The (observed-expected) ² numbers

To get the chi-square value, we just need to replace the terms in the following equation.

                       Chi square= ∑ ((O-E)²/E)

Where,  

X² = ∑ ((O-E)²/E)  

X² = (0.002/269.58) + (65.61/89.86) + (15.2/89.86) + (3.61/89.86) + (8.41/29.95) + (16.81/29.95) + (0.01/29.95) + (9/9.98)

X² = 0.0000074 + 0.73 + 0.17 + 0.04 + 0.28 + 0.561 + 0.0003 + 0.9

X² = 2.6813

Among the (observed-anticipated)² list, there's one price missing. This price corresponds to spherical yellow-grey plants and equals 0.002. This variety became protected withinside the clarification of the problem.

To get the chi-square value, we simply want to update the phrases withinside the following equation.

[tex]Chi square = Sigma((O - E) ^ 2 / E)[/tex]

Where,

[tex]Σ[/tex] is the sum of the phrases

O refers back to the Observed variety of individual

E refers back to the Expected numbers of people

[tex]X ^ 2 = Sigma((O - E) ^ 2 / E)[/tex]

[tex]X^ 2 =(0.002/269.58)+(65.61/89.86)+ Chi quare = Sigma((O - E) ^ 2 / E)[/tex]

Where,

Σ is the sum of the phrases

O refers back to the Observed variety of individual

E refers back to the Expected numbers of people

[tex]X ^ 2 = Sigma((O - E) ^ 2 / E)[/tex]

[tex]X^ 2 =(0.002 / 9.58)+(65.61/ 89.86) + (15.2/89.86)+(3.61/89.86)+(8.41/29.95)+ (16.81/29.95) + (0.01/29.95) + (9/9.98)[/tex]

The model that gives a true representation of a DNA molecule would be the 4th model.

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.
