Answers

Answer: C. The warm surface currents help create storms and fog.

Explanation:

The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)



a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.


b) The two sides of a cell membrane face different environments and carry out different functions.


c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.


d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.

Answers

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.

Explanation:

PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .

PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.

A cotransporter is something that moves two substances across a membrane, one passively and the other actively. The Na+/ K+ ATPase transports sodium and potassium ions across the plasma membrane against their concentration gradients. This pump is not considered a cotransporter because

Answers

Answer:

both ions are transported actively

Explanation:

If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.

A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?

Answers

Answer:

Find the explanation below.

Explanation:

When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.

Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.

Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.

Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

How do active and passive transport help a cell respond to changes in the environment?

Answers

- both transport things across the cell membrane
- help the membrane maintain homeostasis

Active and passive transport help a cell in responding to the changes in the outside environment as both of these processes help in transporting substance into and out of the cell and maintaining the homeostasis in cell.

What is Cellular transport?

Cellular transport is the process of transportation of substances into and out of the cell. Cellular transport includes different processes such as active and passive transport. The active transport requires energy for transporting substances against the concentration gradient and the passive transport does not require energy as the substances move in the direction from high concentration to low concentration of solutes.

The transport of substances which are required by the cell and excretion is possible through active and passive transport. these processes helps in maintaining homeostasis in the cell.

O A. If seed shape did not have a clearly recessive form
B. If having a smooth seed had been a dominant trait
C. If having a wrinkled seed had been a recessive trait
D. If garden peas produced large numbers of offspring​

Answers

Answer:

A. If seed shape did not have a clearly recessive form

Explanation:

To study inheritance patterns, Mendel studied a few characteristics of pea plant -e.g. pea colour, shape, plant height. These characteristics had to be very clear dominant and recessive forms to distinguish between, otherwise detecting the patterns would not have been obvious.

For example, if crossing a wrinkled seed plant with a smooth seed plant made a semi-wrinkled plant, Mendel would not have been able to study the inheritance of dominant and recessive traits.
