In eukaryotic cells, the timing of the cell cycle is regulated by?

Answers

Answer 1

Answer: cyclin-dependent kinases, or CDKs. Cyclin-dependent kinases trigger the transition between cell cyclephases by phosphorylating substrates within the cell.

Why does ice float on liquid water

Answers

Ice can float on liquid water because the ice is less dense so it has an ability to rise to the top of the glass of water.

A single water particle (a molecule) is made up of two hydrogen atoms bonded to an oxygen atom. The oxygen will attract the negative charges in the hydrogen towards it. This will cause the oxygen atom to be negatively charged and the hydrogen atoms to become positively charged. When a liquid freezes, liquid particles move closer together and form strong bonds with one another. There are now more particles in the same area, the solid is denser than the liquid. When water freezes the negative charges on the oxygen push the particles apart. This means that the water becomes less dense with freezing.

Electricity is added to recharge a battery. What is added to ADP to form ATP?A second ribose group
A third phosphate group
A third ribose group
A second phosphate group

I'm thinking third phosphate group?

Answers

Electricity is added to recharge a battery. A third phosphate group is added to ADP to form ATP.

ATP or Adenosine triphosphate contains adenine, ribose and 3 phosphate groups.

ADP is converted to ATP by the following reaction:

ADP+Pi+energy⇄ATP

The analogy between battery and ATP can be explained as ATP is higher energy form and ADP is lower energy form like charged and uncharged form of the battery. When the terminal or third phosphate is removed from the ATP it becomes ADP and releases energy like a battery. The additional phosphate group when added to ADP forms the ATP molecule like the energy spent by the batteries are recharged by putting in additional energy. Here the additional energy is provided by the third phosphate group.

Answer:

The correct answer is B) A third phosphate group.

Explanation:

ATP is Adenosine Triphosphate and ADP is Adenosine Diphosphate.

ADP gets converted into ATP in presence of inorganic phosphate and energy, irrespective of whether the energy is obtained from sunlight or from certain exothermic reactions. ATP is converted into ADP, releasing energy and inorganic phosphate.

Which of the following processes releases energy to be used by a cell?A. A phosphate group is added to atp to form adp.
B. A phosphate group is added to adp to fprm atp.
c. A phosphate group is removed from adp to form atp.
D. A phosphate group is removed from atp to form adp.

Answers

The correct answer is:

D. A phosphate group is removed from atp to form adp.

Explanation:

ATP normally produces energy by breaking down the weak phosphate cell present. The energy delivered due to the breaking down of the phosphate cell is then applied. The ATP is modified to ADP. Whenever a cell feels the necessity for energy it loses a phosphate to assume the energy. It is an automatic and ongoing process. The weak bond between the secondary and the third phosphate is always targeted for converting ATP to ADP. This is the reason ATP is reflected in the main energy money for the cell.

the answer would be D i took this test and got the answer right

The pattern of disproportionate dumping of toxic waste and other forms of pollution in neighborhoods where the poor and people of color live is called

Answers

The pattern of disproportionate dumping of toxic waste and other forms of pollution in neighborhoods where the poor and people of color live is called Environmental Racism.
This involves the placement of low-income or minority communities in the proximity of environmentally hazardous or degraded environments, such as toxic waste, pollution and urban decay. The socially marginalized racial minority communities are subjected to disproportionate exposure of pollutants and/or the denial of access to sources of ecological benefits such as clean water, air, and natural resources.
