Considering the following;
I. Heat is not readily available to all living cells.
II. Heat at excessive amounts denatures proteins.
III. Heat does not provide the activation energy for their reactions.
IV. When a critical temperature is reached, proteins no longer function
Answer;
I and IV
Explanation;
Living cells cannot use heat to provide the activation energy for biochemical reactions because heat is not readily available to all living cells and also when a critical temperature is reached, proteins no longer function.
Too much heat can kill an organism by rendering its organelles, cells, tissues and organs permanently inoperable and un-salvageable. The same process can be observed in tissues at low temperatures, and is the cause of frostbite. This is because enzymes are denatured by high temperature and inactivated by low.
Answer:
They help each other defeat the antigen, The immune system is weaker, and antibodies.
Explanation:
Answer:
100%
Explanation:
The given parental genotype is homozygous for all the genes. According to the given information, both the parents are homozygous for five genes and have genotype "aabbccddee". Since both the parents are homozygous for all the loci, meiosis during gamete formation would result in the formation of all same types of gametes from both the parents.
Both the parents will form all the gametes with an "abcde" genetic constitution. The random fusion of gametes with a given genotype will form all the progeny with genotype "aabbccddee". Therefore, the given parents will produce 100% genetically identical progeny to them.
The sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
<h3>What is diffusion?</h3>
Diffusion is the process by which substances move from region of high concentration to regions of low concentration.
Based on the chart, sodium ions and potassium ions move between the plant cell and pond water by the process of diffusion.
This is because the ions are at higher concentration in the pond water.
During the process, the ions move through ion channels in and out of the plant cell from the pond water.
