Two groups of proteins, called cyclins and cyclin-dependent kinases (Cdks), are responsible for the progress of the cell the. A phosphatase is an enzyme that removes a phosphate group from a protein. Together, these two families of enzymes act to modulate the activities of the proteins in a cell, often in response to external stimuli. Rough the various checkpoints. What genes destroy cancerous cells? The primary function of the p53 gene is to repair or destroy defective cells, thereby controlling potential cancerous cells. This type of gene is called an anti-oncogene or tumor suppressor gene Cancer growth blockers are also called cancer growth inhibitors. They are a type of targeted cancer drug. Our body makes chemicals called growth factors that control cell growth. Cancer growth blockers work by blocking the growth factors that trigger cancer cells to divide and grow. There are many types of cancer growth blockers that work in different ways..

what is the difference in solubility of triglyceride and the products of their hydrolysis

Answers

Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.

Explanation:

Hope this helps.

The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.

Why are triglycerides insoluble?

Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.

This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.

Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.

Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.

Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

What is Mitochondria?

A mitochondrion is defined as an organelle found in the cells of most eukaryotes such as animals, plants and fungi which has a double membrane structure and uses aerobic respiration to generate adenosine triphosphate, which is used throughout used as a source of chemical energy in the cell.

It is known as the "powerhouse of the cell", generating the energy needed for the survival and functioning of the cell.

Through a series of chemical reactions break down glucose into an energy molecule known as adenosine triphosphate (ATP), which is used to fuel various other cellular processes.

recently, state forests and parks like yellowstone national park which contain varieties of flowering trees and shrubs, have started to erect signs that state, take nothing but pictures, leave nothing but footprints. which argument best supports why these signs are being placed in state forests and parks?

Answers

The argument that best supports why the signs are placed in the parks is that humans have the capacity to cause damages to the stability of ecosystems through their actions.

By removing tissues of plants or even entire plants, the stability of the entire park can be disrupted depending on the role such a plant plays in the ecosystem. Some species of organisms in the ecosystem play key roles and their removal or damages may cause significant disruption to the entire ecosystem.

Also, by leaving things that can be harmful to the plant species in parks, immeasurable damages can be done to the entire ecosystem.

The best argument that supports the signs being placed in state forests and parks is: humans are capable of damaging the stability of the ecosystems by removing trees and shrubs.

Different components in an ecosystem interact with each other to ensure biodiversity is sustained. Some species of an ecosystem play important roles and a disruption or removal of such key species would cause disruption in the ecosystem.

Trees and flowers in this said park play important roles in the ecosystem of the park. If they are damaged or removed from the ecosystem, the biodiversity of the ecosystem will be impacted which will cause instability of the ecosystem.

Therefore, the best argument that supports the signs being placed in state forests and parks is: humans are capable of damaging the stability of the ecosystems by removing trees and shrubs.

A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?

Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population

Answers

Explanation:

Why anti-poaching?

Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.

In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.

It is therefore our call to stop the slaughter of rhinos with all our might.
