The answer is; C

This means that the cell has a large volume hence making a lot of products and waste. However, it surface areas of its members are small that the amount is waste that can be removed at any one time is low to enable relief of waste from building up in the cell.

This principle of surface area to volume ratio also applies in loss of heat in animals.Smaller animal loss heat rapidly that larger animals due to the larger surface area to volume ratio of their bodies.

Whitepunk [10]

Answer:

INTERNEUTRONS

Explanation:

INTERNEUTRONS

Interneutrons are really the highest number of neurons and spinal cord. They are accountable for the diverse communication system of the nervous system and try and resolve between inputs and outputs.

Interneurons are groups of nerve cells commonly found in nervous system integrative areas where axons & dendrites are restricted to a specific area of  brain.

Which of the following is not a possible consequence of surface mining?
aleksklad [387]

Answer;

B. improved ecosystem health

Explanation;

-Surface mining is a method of extracting minerals near the surface of the Earth. The three most common types of surface mining are open-pit mining, strip mining, and quarrying.

-The environmental impact of mining includes erosion, formation of sinkholes, loss of biodiversity, and contamination of soil, groundwater, and surface water by chemicals from mining processes.The environmental effects of surface mining include;

  • Habitat destruction
  • Soil erosion
  • Air pollution from dust particulates
  • Pollution (especially from sediments)
  • All surface mining techniques negatively affect the environment, though some methods are more damaging than others.

Cells need to bring in molecules to carry out cellular processes. Often, this requires moving the molecules across the cell memb
aniked [119]

Answer:

B (active transport using ATP)

Explanation:

Movement of substances normally occur in the direction of concentration gradient/difference i.e. the difference in concentration of a substance across a membrane. Letting molecules diffuse or pass down their concentration gradient does not require energy but pumping those molecules against gradient requires energy in form of Adenosine triphosphate (ATP). This process is called Active transport.

In order to perform certain cellular processes, cells need to move substances from their surroundings into the cell across their cell membrane. Moving this substances against the concentration gradient between the cell membrane and its extracellular fluid requires energy (ATP).

An example is the sodium-pottasium pump employed by animal cells in which they expend energy to move K+ molecules into the cell and Na+ molecules outside the cell against the concentration gradient of their cell membrane and extracellular solution.

Can genetic mutations benefit an organism? Explain your answer.
pochemuha

There are several mutations that benefit the organism.A well known example is the antibiotic resistance developed by bacteria, which aid in their survival even when they are exposed to a given antibiotic. A single gene mutation in wild almond trees resulted in a variety that no longer synthesizes amygdalin.
