Cellular respiration in living tissues is reduced at low temperatures. The amount of kinetic energy needed for chemical reactions like cellular respiration to occur decreases as temperature rises. Thus, option A is correct.
What importance of cellular respiration in an organism?As oxygen tension dropped, so did breathing rate, which eventually reached nil at low oxygen tensions.
Cell density had no bearing on this outcome. We provide a model to explain the observed impact of oxygen tension on cellular oxygen uptake.
As a result, increased cellular respiration is often associated with warmer temperatures.
Carbon dioxide concentration: The rate of respiration is inversely correlated with carbon dioxide concentration.
Increased carbon dioxide levels and a lack of oxygen have a negative impact on aerobic respiration rate.
Therefore, cellular respiration is the metabolic process that breaks down organic molecules to release energy to be used by cells.

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer:
92 daughter chromosomes.
Explanation:
There are 46 chromosomes in a normal cell and each chromosome turns into 2 daughter cells. So 46 plus 46 is 92.
What is the correct sequence in the transmission of a neural impulse?

Answer:
THE use of energy (usually in the form of ATP) is necessary for the process of active transport to occur.
Energy in form of ATP is necessary for the process of active transport to occur.
WHAT IS ACTIVE TRANSPORT:Active transport is the type of transport that involves the movement of molecules with the aid of energy (ATP). Active transport uses energy to move molecules against a concentration gradient unlike passive transport.Therefore, this means that energy in form of ATP is necessary for the process of active transport to occur.

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.
In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.
Answers: A,B,D
Explanation: :I took the test and got this question right .
The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.
In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.
Therefore the statement below about anaphase is correct.
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.
That is, the cell now has 92 chromosomes which is enough DNA for two cells.
Therefore the statement below about interphase is correct.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.
The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.
Therefore the statement below about prophase is correct.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.Learn more here:

in the family the father is affected by a genetic disorder the son in the family has the same disease but the daughters do not have it. what type of inheritance is this ?
Answer:
Explanation:When a genetic disorder is diagnosed in a family, family members often want to know the likelihood that they or their children will develop the condition. This can be difficult to predict in some cases because many factors influence a person's chances of developing a genetic condition. One important factor is how the condition is inherited.

Why is ATP known as the energy currency?
5 line answer plz
Answer:
ATP is commonly referred to as the "energy currency" of the cell, as it provides readily releasable energy in the bond between the second and third phosphate groups. ... As a result, cells within the human body depend upon the hydrolysis of 100 to 150 moles of ATP per day to ensure proper functioning.In addition to providing energy, the breakdown of ATP through hydrolysis serves a broad range of cell functions, including signaling and DNA/RNA synthesis. ATP synthesis utilizes energy obtained from multiple catabolic mechanisms, including cellular respiration, beta-oxidation, and ketosis.
Explanation: is this good enough?
Answer:
Because its a sequence in which molecules can store their own energy and use it when needed such as in a chemical reaction , note that this is the main reason some molecules stay dormant during a chemical reaction and that is because they didn't use ATP
Explanation:
The principal molecule for storing and transferring energy in cells. It is often referred to as the energy currency of the cell and can be compared to storing money in a bank. ...

If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis
Answer:
3
Explanation:
If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.
What is meiosis?
In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm).
Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent). The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state.
Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.
Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent. The appropriate number of chromosomes in a cell is crucial.
Therefore, If you start off with 12 strands of chromatin how many strand of chromatin do you need to end up with in each cell after meiosis after 3 stages.

What are some ways that the biosphere interacts with the other three systems?
Answer:
Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants.
Explanation:
Answer :Full Answer. A classic example of an interaction between spheres is when a plant (part of the biosphere), takes carbon dioxide from the atmosphere and water (the hydrosphere) through its roots from underground (geosphere) to perform photosynthesis, which provides the plant with food and releases oxygen into the atmosphere.
