List some reasons why a cell that has just completed cytokinesis might enter the G0 phase instead of the G1 phase.

6 0

Answer:

G0 phase is the phase of the cell cycle in which cell neither divides nor prepare to divide that is become quiescent. This phase is also known as the quiescent phase. The quiescence phase can be categorized into two types on the basis of function : reversible quiescence and irreversible quiescence.

The cells enter this phase due to the following reasons:

1. The cells which mature and attain functions and do not wants to divide again like heart cells and nerve cells.

2.. The cells like oocytes are arrested at the G0 phase which again becomes functional at puberty to form ova .

explain how a carrier protein can facilitate the diffusion of glucose or other substances into the cell.
Sveta_85 [38]

Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.

How carrier protein facilitate the diffusion?

When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.

Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.

Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.

Which situation would most likely increase the carrying capacity for humans
vredina [299]

C. A new source of freshwater

Explanation:

The situation that would most likely increase the carrying capacity for humans in a certain region is the availability of new sources of freshwater.

In ecological terms, the carrying capacity of a place is the the number of people, animals, or crops which a region can support without environmental degradation.

  • A new source of freshwater provides new resources for the ecosystem.
  • In the freshwater, more fishes are available, more plants can grow around and a lot of biological activities can progress.
  • Water is essential for life.
  • Fresh water sources are incentives for choosing to live in a place or not.
  • A fresh water source increases the carrying capacity for humans in a certain region.

What happens when an electrical gradient and a chemical gradient are applying opposite forces to active transport?
Ierofanga [76]

Answer:

Option B, they negate each other

Explanation:

Electrical gradient force is more or less equal to the chemical gradient during an active transport. The number of electron produced during the establishment of chemical gradients, were transferred through the cellular circuit to produce electrical gradient of an equivalent amount in opposite path.

Thus, both electrical and chemical gradient are opposite to each other and hence they negate out each other.

Option B
