Inactivation of a cell-surface receptor depends on: the activity of phosphatases in the cytosol. the release of the ligand from the receptor ligand binding site. the concentration of ligand surrounding the cell. the binding affinity of the receptor.
Answer:
the release of the ligand from the receptor ligand binding site.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Inactivation of a cell-surface receptor depends on the release of the ligand from the receptor ligand binding site. This ultimately implies that, the concentration of ligand surrounding a cell, as well as the binding affinity of the receptor significantly affects the inactivation of a cell-surface receptor such as receptor kinase.
The inactivation of a cell-surface receptor depends on solely the concentration of ligand surrounding the cell.
A ligand which has the ability to bind to and alter the function of the receptor that triggers a response is called a receptor agonist. On the other end, ligands that bind to a receptor but fail to activate the response are receptor antagonists.
Ligand cellligand is any molecule or atom that irreversibly binds to a receiving protein molecule, otherwise known as a receptor. When a ligand binds to its respective receptor, the shape and/or activity of the ligand is altered to initiate several different types of cellular responses.
Futthermore, molecules such as hormones and drugs that bind to a receptor are called ligands. The binding can be specific and reversible.A ligand may activate or inactivate a receptor; activation may increase or decrease a particular cell function

What is the biggest difference between the geocentric model and the heliocentric model
Answer: The main difference is that the geocentric has the Earth at the center, and the heliocentric has the sun at the center. The geocentric model says that the earth is at the center of the cosmos or universe, and the planets, the sun and the moon, and the stars circles around it. The early heliocentric models consider the sun as the center, and the planets revolve around the sun.

Which statement best descrſoes photosynthesis?
a. when plants produce their own water
b. when plants produce their own sugar
C. when plants produce oxygen and carbon dioxide
d. when plants self-pollinate
Answer:
b. when plants produce their own sugar
Explanation:
Let's look at the products of photosynthesis! During the process of photosynthesis plants break apart the reactants of carbon dioxide and water and recombine them to produce oxygen (O2) and a form of sugar called glucose (C6H12O6).
Glucose provides plants with needed food through a process called photosynthesis. This process helps plants convert the energy they take in from sunlight into sugar to nourish the plant. Photosynthesis occurs when carbon dioxide, water and sunlight are combined. Plants use these to form glucose and oxygen.

How does gravity affect objects of different mass close to Earth, and how does that effect
change as an object moves farther from Earth
Answer: Gravity is the universal force of attraction. ... This force of gravitational attraction is directly dependent upon the masses of both objects and inversely proportional to the square of the distance that separates their centers. This means that as you move away from an object the gravitational force decreases.
Explanation:
In this question we are going to answer two questions about the gravitational force that keeps us grounded.
How does gravity affect objects of different mass near Earth?The force of gravity between two objects is the product of their masses divided by the square of the distance between them. That is, the more mass an object has and the closer it is, the greater its force of attraction on another object.
How does it affect change as an object moves away from Earth?The gravitational force decreases, and the object begins to be attracted by other gravitational forces besides that of the earth.
With this information, we can conclude that the gravitational force of the earth keeps us attached to it, and as we move away from the earth we lose these forces of attraction.

How is the liver adapted to its regulatory functions
Answer:
The liver controls most chemical levels in the blood. It also secretes a clear yellow or orange fluid called bile. Bile helps to break down fats, preparing them for further digestion and absorption. All of the blood leaving the stomach and intestines passes through the liver.

1. There are two types of viral architectures, one is naked and the other is enveloped. Please answer the following questions. A. What are the essential structural components and their functions of a naked virus? B. What molecules can be founded on the viral envelop? Explain the sources of these molecules. C. Is naked or enveloped virus more sensitive to detergent and alcohol? Explain your reasons.
Answer:
Naked viruses do not have a phospholipid membrane.
Explanation:
Nonenveloped or naked viruses do not have a phospholipid membrane outside their capsid and remain naked to the external environment. The envelopes are consists of portions of the host cell membranes i.e. phospholipids and proteins as well as some viral glycoproteins are also present in the envelop. Enveloped virus is more sensitive to detergent and alcohol as compared to naked virus because the naked virus has resistance against environmental factors which is absent in the enveloped virus. Once the envelop removed or broken, the virus loses its functional receptors and is not able to cause infection to susceptible cells.

What is the general relationship between distance from the sun and a planets density?
Answer:
There is no connection between a planet's distance from the Sun and its rate of rotation (spin on its own axis or Planetary Rotation Period). While it is true that, generally speaking, the gas giants have higher rotation rates than the earth like planets closer to the Sun, any correlation is only coincidental.

Explain what is “bottleneck” and why genetic drift is more powerful in small populations.
Answer:
because more is being forced through
Explanation:
Answer:
A bottleneck in genetics is an event that kills off or isolates a large portion of the population.
Explanation:
The more individuals in a population, the greater the genetic diversity. A genetic bottleneck happens when the number of individuals in a population gets greatly reduced. This happens as a result of random chance. For example, a storm might come through and knock down a bunch of trees. Birds that live in the trees may get harmed and those that survive now have to find a new home, so they migrate to other areas leaving behind a small population. This is important because the fewer individuals there are, the less genetic diversity and therefore, the less ability of the population to adapt. If you have lots of different genes available and a new disease arises in the population, it's more likely that some individuals will survive. If you only have a few genes available, it is less likely any individuals will survive. This can lead to really quick adaptation and evolution of a species.

A rock contains a radioactive isotope that decays to half of its original
amount in 5 million years. When this rock formed, it was made up of 100%
of the radioactive isotope, and 0% of the new element that it decays
If you find this rock and analyze it, and find that it contains only 50% of the
radioactive isotope and 50% of the new element, how old must this rock
be? *
1) 2.5 millon years
2) 10 million years
3) 5 million years
4) 15 million years
Answer:
3) 5 million years
Explanation:
The rock is 5 million years old because the rock contains only 50% of the radioactive isotope. We know that this rock decays to become half in 5 million years. Initially, the rock has 100% of radioactive isotope and 0% of the new element that forms with the decaying of the rock. But 50% of the radioactive isotope decays and 50% of the new element is formed so we can say that it reaches to its half age which is 5 million years.
