Signal transduction pathways that include a phosphorylation cascade

are generally initiated by a phosphorylase enzyme and limited to one step
are generally inactivated by a kinase enzyme and decrease signal transduction efficiency
are propagated by steroid hormone receptors to reach the final cellular response in one step
cause a structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein

Answers

Answer 1

Answer:

Signal transmission paths Learn how signals are transmitted within a cell from the cell membrane receptor. The chains of molecules that pass intracellular signals are known as intracellular signal transduction pathways.

Answer 2

Signal transduction pathways that include a phosphorylation cascade cause a structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein. Thus, the correct option for this question is D.

What is the Phosphorylation cascade?

The Phosphorylation cascade may be characterized as a series of signaling pathways that significantly involve the activation of one enzyme through the effect of other in order to accomplish the downstream signaling pathway.

According to the context of this question, the process of phosphorylation involves the addition of a phosphate group over the compound in order to stimulate its activity. This is accomplished by the structural change in each phosphorylated protein, with the addition of a phosphate group to activate the protein.

Therefore, the correct option for this question is D.

Give the functions of the following parts of the respiratory system - Nostril - trachea - bronchiole - alveoli - pharynx - larynx - lungs  - ribs - diaphragm                                                                   

Answers

Answer:

Respiratory System: The respiratory system's main job is to move fresh air into your body while removing waste gases.

Nostril: To warm air on inhalation and remove moisture on exhalation.

trachea: Serves as passage for air, moistens and warms it while it passes into the lungs, and protects the respiratory surface from an accumulation of foreign particles.

bronchiole: To deliver air to a diffuse network of around 300 million alveoli in the lungs.

alveoli: To exchange oxygen and carbon dioxide molecules to and from the bloodstream during breathing.

pharynx: Helps the respiratory system by allowing air to make its way to the respiratory tract.

larynx: Produces vocal sounds and prevents the passage of food and other foreign particles into the lower respiratory tracts.

lungs: To help oxygen from the air we breathe enter the red cells in the blood.

ribs: To aid respiration and help protect the lungs.

diaphragm: Contracts and flattens when you inhale. Creates a vacuum effect that pulls air into the lungs, and relaxes when exhaling.

use numbers to arrange the events of a demographic transition in order in which they occur

is this correct?​

Answers

the order is 1,4,2 then 3.

(DTM) is defined by a country's death rate dropping quickly while its birth rate staying high. Because of this, a nation in Stage 2 will show an increase in its general population—not because the birth rate is rising, but because births outnumber deaths.

What are the different events of a demographic transition?

The demographic transition model was initially proposed in 1929 by demographer Warren Thompson. The four stages of the paradigm are pre-industrial, urbanizing and industrializing, mature and post-industrial.

Stage 1: Slow population growth is caused by high birth and mortality rates. Stage 2: While the birth rate stays high and the death rate declines, population growth accelerates. Stage 3: Population growth slows as the birth rate starts to decline.

Therefore,  1,4,2 and 3. It is correct events of a demographic transition in the order in which they occur.

Removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat

What is Deforestation?

Deforestation also known as forest clearance is defined as the removal of forest or stands of trees from land that is converted to non-forest use in which forest land is converted into farms, ranches or urban may involve converting to use. The most concentrated deforestation occurs in tropical rainforests.

It occurs when humans remove or thin forests for timber or use land where trees stand for crops, grazing, extraction such as mining, oil, or gas, or as populations grow and people move. Development takes place in the form of migration.

Wildlife habitats are fragmented due to deforestation, where native species have to live on remaining habitat islands that are surrounded by disturbed land being used for agriculture and other uses.

Thus, removal of trees and other types of vegetation can reduce the availability of food, shelter and breeding habitat

After phosphates and nitrates have entered a water
system, identify the correct steps of Eutrophication.
I. Oxygen levels drop
II. Underwater plants die
III. Fish and invertebrates die
IV. Algae grows rapidly
A. II, III, IV, I
B. IV, II, I, III
C. I, III, IV, II
D. III, II, I, IV

Answers

After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.

Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.

Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:

Algal bloom: the nutrients facilitate the rapid growth of algaeThe bloom of algal species results in the death of underwater plants as a result of inadequate light.The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxia

Therefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

What is natural selection?

Natural selection is the process by which species evolve over time as the prevalence of certain traits increases or decreases in a population.

Natural selection, the mechanism by which species evolve over time, is depicted in the flowchart.

Overproduction of offspring causes competition for limited resources, resulting in a struggle for survival.

Based on their inherited characteristics, some people are better equipped to survive and reproduce than others.

These people are said to be "fit," and they are more likely to pass on their positive traits to their children. These advantageous traits become more common in the population over time, causing changes in the species as a whole.

Thus, the correct option is 4.

An actin-binding protein called cofilin binds preferentially to ADP-containing actin filaments rather than ATP-containing actin filaments. Based on this preference, which is true? Question 7 options: Cofilin binds to the plus ends of treadmilling actin filaments. Cofilin competes with profilin for binding to actin. Cofilin binds to older actin filaments. Cofilin binds to the plus ends of actin filaments.

Answers

Answer:

Cofilin binds to older actin filaments

Explanation:

Microfilaments (also called actin filaments) are a class of protein filament common to all eukaryotic cells, which consist of two strands of subunits of the protein actin. Microfilaments form part of the cell's cytoskeleton and interact with the protein myosin in order to allow the movement of the cell. Within the cell, actin may show two different forms: monomeric G-actin and polymeric F-actin filaments. Microfilaments provide shape to the cell because these filaments can depolymerize (disassemble) and polymerize (assembly) quickly, thereby allowing the cell to change its shape. During the polymerization process, the ATP that is bound to G-actin is hydrolyzed to ADP, which is bound to F-actin. ATP-actin subunits are present at the barbed ends of the filaments, and cleavage of the ATP molecules produces highly stable filaments bound to ADP. In consequence, it is expected that cofilin binds preferentially to highly stable (older) filaments ADP-actin filaments instead of ATP-actin filaments.
