Answer:
Moreover, carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only. Both carrier proteins and channels proteins also differ in their chemical composition - whilst the former are glycoproteins, the latter are lipoproteins.
Explanation:

Carrier proteins can carry out both active and passive transportation of solutes, whereas channel proteins bring about passive transport only.
What are the functions of carrier proteins?Carrier protein is a type of cell membrane protein involved in facilitated diffusion and active transport of substances out of or into the cell. Carrier proteins are responsible for the diffusion of sugars, amino acids, and nucleosides.
Moreover, carrier proteins bind specific solutes and transfer them across the lipid bilayer by undergoing conformational changes that expose the solute-binding site sequentially on one side of the membrane and then on the other.
Membrane carrier proteins are important transmembrane polypeptide molecules which facilitate the movement of charged and polar molecules and ions across the lipid bilayer structure of the cell membranes.

The observable trait appearing probability for cross-breeding is the phenotype ratio in a Punnett square.
What is cross-breeding?The act of creating offspring, particularly through the mating of two purebred individuals who are from different breeds, variations, or even species, is known as crossbreeding. The practice is specifically referred to as designer crossbreeding because it is typically done with the intention of developing offspring that would acquire desired qualities of the parent lineages. Breeders frequently engage in this approach, particularly when the intended qualities will be advantageous to the progeny, such as when its biological fitness is improved.Hybridization and crossbreeding are sometimes used interchangeably. But specifically, hybridization is the act of creating hybrid offspring by mating two parents from different species.To learn more about cross-breeding, refer to

why do chloroplasts make energy carriers during the light reactions?
Answer:
consist of array of chlorophyll molecules. *** The absorb energy excited electrons to a higher energy level. ... *** As H+ diffuse through ATP synthase, down their concentration gradient, the enzyme uses the energy of the moving ions to ATP.
Explanation:
Chloroplasts make energy carriers such as NADPH in which the light energy is caught up. Together with carbon dioxide they are used to synthesis glucose during light reaction in photosynthesis.
What is light reaction in photosynthesis ?The first series of events that start the process of photosynthesis require light and are referred to as light reactions or light-dependent reactions since they depend on light as their energy source.
Light energizes the electrons in the chlorophyll molecule as it reaches the chloroplast. These electrons accelerate to higher energy levels because they have taken in or caught that energy and are now carrying it. Excited electrons have high energy. Who wouldn't be thrilled to have the capacity to sustain life?
Chlorophyll is left at a loss when the excited electrons depart to take part in other reactions; eventually, they need to be replaced. In order to break water molecules during that replacement process, an enzyme complex and light are both necessary. Hence, energy carriers plays a significant role in light reaction.

Explanation:
Genetic Diversity is in fact the overall range of individual and varying characteristics in a population. Genetic diversity is what makes different organisms and species unique, and even usher in traits that become favorable for survival. Without genetic diversity, many species would die out before evolving (because it would be near impossible to evolve with their surroundings without genetic diversity).

Lactic acid fermentation can be modeled by which equation?
O Lactic acid + NADH → Pyruvic acid NADH
O Pyruvic acid + NAD+ → Lactic acid + NADH
O Lactic acid + NADH → Pyruvic acid + NAD+
O Pyruvic acid + NADH → Lactic acid + NAD+
Lactic acid fermentation can be modeled by the following equation: Pyruvic acid + NADH → Lactic acid + NAD+
LACTIC ACID FERMENTATION:
Fermentation is a process undergone by some anaerobic organisms. Ideally, the process of cellular respiration proceeds as follows in the presence of oxygen: Glycolysis- Kreb cycle - ETC. However, in the absence of oxygen (anaerobic condition), the product of glycolysis which is pyruvic acid combines with an electron carrier (NADH) to give rise to lactic acid and NAD+. This means that pyruvic acid is reduced while NADH is oxidized as modelled in the following equation:Pyruvic acid + NADH → Lactic acid + NAD+Learn more at: https://brainly.com/question/11502989?referrer=searchResults
Answer to Question 1:
Well, given the choices to the question above 'Lactic acid fermentation can be modeled by which equation?', I would say that the best choice would be 'Pyruvic acid + NADH → Lactic acid + NAD+', or in other words, Option D.
Explanation for Question 1:
For a further explanation expanding more on the first question and showing why, the user above's answer is super helpful.
Answer to Question 2:
For the additional question asked 'In the Krebs cycle, how is citric acid formed?', I didn't see the options, however I believe they are:
O Carbon dioxide bonds with a chain of coenzyme A.
O Pyruvic acid molecules are broken down by an acetyl group.
O Acetyl-CoA joins with a large molecule called ozaloacetic acid.
O Enzymes combine hydrogen ions, oxygen, and electrons.
^ This being said, I would say your best choice would be Option C.
Explanation for Question 2:
The Krebs cycle begins when acetyl-CoA combines with a four-carbon molecule called OAA, aka oxaloacetate. This begins to produce citric acid, in which has six carbon-atoms. This is why the Krebs cycle is also referred to as 'the citric acid cycle.'

Answer:
The answer is B (An estuary)
Explanation
The picture depicts a mangrove swamp within Florida Everglades. This means that the Everglades is most likely Estuary due to the presence of mangrove trees thriving in both freshwater and saltwater environments. The correct option is (B).
The picture shows a mangrove swamp in a section of the Florida Everglades. Mangroves are unusual trees that have the amazing capacity to thrive in both freshwater and saltwater environments. Estuaries, where rivers meet the sea and create a setting with variable salt levels, are notable for this adaptability.
The Florida Everglades is a perfect example of an estuary environment since the coexistence of mangroves in this ecosystem implies the presence of brackish water, which is a mixture of freshwater and seawater.

How long does it take the Earth to move from Point A to Point C?
Answer:
Explanation:
As you know that the earth has two types of motions,
namely rotation and revolution. Rotation is the
movement of the earth on its axis. The movement of
the earth around the sun in a fixed path or orbit is
called Revolution.
The axis of the earth which is an imaginary line,
makes an angle of 66½° with its orbital plane. The
plane formed by the orbit is known as the orbital plane.
The earth receives light from the sun. Due to the
spherical shape of the earth, only half of it gets light
from the sun at a time (Figure 3.2). The portion facing
the sun experiences day while the other half away from
the sun experiences night. The circle that divides the
day from night on the globe is called the circle of
illumination. This circle does not coincide with the
axis as you see in the Figure 3.2. The earth takes about
24 hours to complete one rotation around its axis.
The period of rotation is known as the earthday. This is
the daily motion of the earth.
2021–22
MOTIONS OF THE EARTH 19
Figure 3.3 : Revolution of the Earth and Seasons
What would happen if the earth did not rotate? The
portion of the earth facing the sun would always
experience day, thus bringing continuous warmth to
the region. The other half would remain in darkness
and be freezing cold all the time. Life would not have
been possible in such extreme conditions.
