If a GPCR lost the capability to release GDP: A. the receptor would be permanently activated. B. the receptor would not be able to be activated. C. the alpha subunit would detach. D. the beta subunit would detach.

Answers

Answer 1

If a GPCR lost the capability to release GDP, the receptor would not be able to be activated (Option B).

GPCRs, or G-protein coupled receptors, are membrane proteins that play a crucial role in signal transduction. They are activated when a ligand binds to the receptor. The GPCR is then able to exchange GDP for GTP on the alpha subunit of the associated G-protein.The exchange of GDP for GTP allows the activation of the G-protein and subsequent downstream signaling. If a GPCR lost the capability to release GDP, the G-protein would be unable to exchange GDP for GTP, which is an essential step for activation. As a result, the GPCR would remain inactive and would not be able to initiate any downstream signaling. The alpha subunit would not detach (Option C), and the beta subunit would not detach (Option D) because these events are dependent on the GPCR's activation. Similarly, the receptor would not be permanently activated (Option A), as the inability to release GDP would prevent activation altogether.Hence the correct answer is Option B.

What method do scientists use to trace plant and animal extinctions through Earth's history

Answers

Answer:

Paleontology is the study of the history of life on Earth as based on fossils. Fossils are the remains of plants, animals, fungi, bacteria, and single-celled living things that have been replaced by rock material or impressions of organisms preserved in rock.

Explanation:

Because there are very few ways of directly estimating extinction rates, scientists and conservationists have used an indirect method called a “species-area relationship.” This method starts with the number of species found in a given area and then estimates how the number of species grows as the area expands.

This map shows the counties in Montana that are prone to dam failure. If you were in charge of flood control in Montana, where would your biggest areas of concern be? What other data would you collect about these areas or about local weather patterns to help you make a flood-control plan for the state?

Answers

Answer:

The focus would be the western side of the state and several counties in the central part of the state because there are many high-risk dams in these areas. Knowing what communities and structures are located around these dams, the average precipitation rate, and projected rainfall totals would be helpful in designing a flood-control plan. Knowing the age and condition of each dam would be important for setting priorities in the plan.

Answers

The most likely cause of the effect shown in the given photograph is Acid deposition.

What are the causes of Air pollution?

The causes of air pollution include excessive burning of fossil fuels, industrial emissions, carbon emissions from automobiles, construction and industrial wastes, etc.

Acid deposition may be also known as Acid rain. It includes the form of precipitation with several acidic components like nitric acid and sulfuric acid.

These precipitations finally falls on the earth from the atmosphere in the form of rain, snow, fog, etc., and are deposited on tall trees, buildings, and objects, and lose their natural beauty.

Therefore, the most likely cause of the effect shown in the given photograph is Acid deposition.

What concept suggests that small bacteria were engulfed by larger cells to become mitochondria and help to self flourish and become a eukaryotic cell

Answers

Answer:

Endosymbiotic theory

Explanation:

The concept that hypothesized that small bacteria were engulfed by larger cells to become the mitochondrion  and eventually become a eukaryotic cell is known as symbiogenesis or the endosymbiotic theory.

The endosymbiotic theory argues that organelles like mitochondrion and the chloroplast found in modern-day eukaryotic cells were formerly prokaryotic microbes. These microbes got ingested by primitive, amoeba-like eukaryotic cells that were first formed but instead of dying, the engulfed microbes found a way to symbiotically coexist with their hosts, eventually forming the organelles - aerobic microbes forming the mitochondrion and photosynthetic microbes formed the chloroplast.

Which organelles must work together to provide food and energy to a plant cell?

Answers

Answer:

Mitochondria are the working organelles that keep the cell full of energy. In a plant cell, chloroplast makes sugar during the process of photosynthesis converting light energy into chemical energy stored in glucose.

Chloroplast and mitochondria are organelles that must work together to provide food and energy to a plant cell.

Plants are living organisms that are capable of nourishing themselves from inorganic substances.

The complex chemical process by which they manage to do so is called photosynthesis and it takes place in chloroplasts.

Chloroplasts are elliptical-shaped organelles - their number varies between 20 and 100 in each plant cell - found in leaves and possessing the enzymatic machinery necessary to transform solar energy into chemical energy and, finally, into food.

The plant cell needs energy to grow and multiply and the mitochondria provide most of this energy by performing the last stages of the breakdown of food molecules.

Its main function is to supply the electron carriers (ATP), a product of cellular respiration, which provide the energy that the cell needs.

Therefore, we can conclude that within the leaves of plants, in the chloroplasts of plant cells, the chemical process that transforms inorganic matter into food takes place and the mitochondria are the energy-producing organelles.
