Answer:
Active transport is important for cellular function because it moves important items, such as calcium and glucose, into and out of cells.
Explanation:
Proteins sit on the cell membrane, with one part inside and one part outside the membrane. If these items don't cross the membrane, the cell can die.

Assume that one molecule of glucose enters glycolysis in a red blood cell, generating two molecules of glyceraldehyde 3-phosphate. Both molecules enter the payoff phase. One molecule enters the Rapoport-Luebering shunt, while the other does not. How many net molecules of ATP are produced from this molecule of glucose
Answer:
From glycolysis only 8 ATP molecules are obtained
Explanation:
The 8 molecules of glycolysis 6 come from NADH, which is the one that carries these molecules by dissociating, giving NAD + H + as a product.
The metabolic pathway of glucose actually generates 38 ATP, but this value would be the sum of 8 from glycolysis, 6 from the pyruvic acid pathway and 24 from the krebs cycle ... These last two pathways are part of cellular respiration .
Which is a result of a seasonal change (meaning a change that happens over
and over at a certain time of year)?
A. Plankton dying due to an oil spill
B. Frogs digging into mud to hibernate in the winter
C. Grass dying due to overgrazing
D. Fish moving away from a polluted site and into cleaner water
Answer:
b
Explanation:
the winter is a season
The answer is B. Frogs digging into mud to hibernate in the winter is a seasonal change that happens every year as temperatures drop in the winter.
What can be with case of planktons ?Plankton dying due to an oil spill, grass dying due to overgrazing, and fish moving away from a polluted site and into cleaner water are not necessarily tied to seasonal changes, but can occur due to other factors such as pollution, climate change, or human activities.
A seasonal change is a natural occurrence that happens regularly and predictably during certain times of the year. These changes are often triggered by shifts in the amount of sunlight, temperature, and precipitation that occur as the Earth moves through its annual orbit around the sun.
Some common examples of seasonal changes include the arrival of spring flowers, the turning of leaves in the fall, and the migration of birds in the winter.
In the case of frogs digging into mud to hibernate in the winter, this is a natural response to the colder temperatures that occur during the winter months.
As temperatures drop, frogs begin to slow down and their metabolism slows, causing them to seek out shelter and protection from the cold. By digging into the mud, they are able to protect themselves from freezing temperatures and other harsh winter conditions.
In contrast, the other examples given - plankton dying due to an oil spill, grass dying due to overgrazing, and fish moving away from a polluted site and into cleaner water - are not necessarily tied to seasonal changes.
These events can occur at any time of year and are often caused by human activities such as pollution, climate change, and overuse of natural resources.
While these events may have a significant impact on the environment, they do not represent the natural, predictable seasonal changes that occur as part of the Earth's natural cycles.

What is ponds ?
A pond is a tiny body of water that is still. A lake is a sizable body of water that remains still. Few lakes contain water, however the majority of lakes do. An example of a salty lake is the Great Lake in Utah.
In certain huge lakes, the water may be so deep that sunlight may not reach the very bottom. Water plants and algae cannot survive on the lake bottom without sunlight. That's because photosynthesis in plants need sunshine.
Water for lakes and ponds can come from a variety of places.

Why is ATP important in the metabolism or organisms? a. It hydolyzes to add free energy to exergonic reactions. b.The terminal phosphate bond has higher energy than the other two phosphate bonds. c. The terminal phosphate is held by a strong covalent bond that when hydrolizes, captures free energy. d. ATP provides energy coupling between exorgonic and endergenic reations
Answer:
ATP provides energy coupling between exergonic and endergonic reactions.
Explanation:
Adenosine triphosphate is an important molecule found in the cells and its role is to transport energy that is necessary for the cell or metabolic activities. These activities include muscle contraction and nerve impulse propagation. The ATP provides energy to both the energy consumption actions and energy-releasing reactions and thus needs a small amount of input of energy. The chemical bonds on breaking provide energy for cells to work.You are attempting to see if a suspect is associated with a crime.

Answer:
There are no options in this question but generally a sample of DNA can be increased;
By using Polymerase Chain Reaction (PCR) technique.
Explanation:
This question describes the application of making molecular biology to solving a crime problem; a branch called forensics. In this case where an insufficient small amount of DNA sample was recovered from the blood in a crime scene, the polymerase chain reaction technique, commonly known as PCR can be used to increase the DNA sample.
In the 1980's, a molecular technique used to amplify part of a template DNA strand to produce several copies of it, was invented by Kary Mullis and his colleagues. This amplification refers to the numerical increase in the number of DNA sequence.

B. lived in close contact with water
Explanation:This is because we now that the area near water is very fertile so it most probable that the earliest trees grew there and slowly spread to the other parts
The earliest land plants can best be described as having been in intimate touch with water. So, the correct option is B.
What are Plants?The kingdom Plantae, which is primarily composed of photosynthetic eukaryotes, includes plants. They are largely multicellular. In the past, algae and fungi were included in the plant kingdom, which comprised all living organisms that were not animals.
Plants are vital components of nature and living things. The act of photosynthesis allows them to produce their own sustenance. Because of the existence of a substance called chlorophyll, plants appear green in colour. Direct energy production from sunlight occurs in plants through photosynthesis. It is better to think of the earliest terrestrial plants as having had close contact with water.
