Which would probably have the greatest effect on a protein's function
Answer:
Tertiary Structure
Explanation:
Proteins are made up of amino acid units. The four types of protein structure are primary, secondary, tertiary, and quaternary.
From the given options, the greatest effect on a protein's function is caused by tertiary structure because it has branched structure and have several side chains. These side chains can interact in different ways and can change the effect on a protein's function.
Hence, the correct answer is "Tertiary Structure".
*urgent* What is the genetic information called in Anaphase II? What is another source of genetic variation during metaphase I?
Explanation:
Metaphase II: Chromosomes line up at the metaphase plate. Anaphase II: Sister chromatids separate to opposite ends of the cell. Telophase II: Newly forming gametes are haploid, and each chromosome now has just one chromatid.
A flea and dog are an example of (commensalism herbivory mutualism parasitism) , because the flea irritates the dog's skin and feeds on its blood. Certain bacteria live in the digestive tract of humans , and their relationship is an example of (commensalism / herbivory mutualism parasitism) because the bacteria help humans to break down the food they eat. Cattle egrets eat insects off the back of an elephant, which is an example of (commensalism herbivory mutualism/ parasitism) because the cattle egrets benefit without either harming or helping the elephants.
Answer:
parasitism
mutualism
commensalism
Explanation:
Commensalism is defined as a relationship between two living organism in which one organism get benefits and the other organism neither benefit nor harm.
Herbivory is defined as the relationship between organisms and plants in which organisms consume plant material.
Mutualism is defined as the relationship between two living organism in which both organisms benefit each other.
Parasitism is defined as the relationship between two living organism in which one organism get benefits and the other organisms get harmed.
So, a flea and dog are an example of parasitism, certain bacteria live in the digestive tract of humans is an example of mutualism, and relationship between cattle egrets and an elephant is an example of commensalism.
Hence, the correct answer is:
parasitism
mutualism
commensalism

how does mutation affect the outcome of a population in terms of Evolution.
Genes code for specifically structured
sugars.
acids.
lipids.
proteins.
Genes code for specifically structured proteins. The majority of genes have the necessary instructions to produce the useful molecules known as proteins, hence option D is correct.
The segment of DNA needed to make one protein is known as a gene, because they code for proteins consisting of hundreds or thousands of amino acids, genes often have hundreds or thousands of base pairs.
The ribosome, a specialized complex that "reads" the sequence of mRNA nucleotides, interacts with the messenger RNA (mRNA). A codon is a group of three nucleotides that typically codes for one specific amino acid.

· If an owl regurgitates an average of 2 pellets a day and the average number of prey in one
pellet is 4, how many rodents could be eliminated in one year (assume there are 365 days a
year)? Show your work.
Answer:
2920 rodents could be elimated a year by the owl if the population of rodents could continue to survive with this bird around.
Explanation:
2x4 because 1 pellot is 4 preyy
2 pellots is 8 prey
8 prey for 1 day
8 x 365
not leap year so don;t say 356
so 2920

why is kidney cell different from other cells in your body ? what role do stem cells play?
Answer:
1. Cells have different shapes because they do different things. Each cell type has its own role to play in helping our bodies to work properly, and their shapes help them carry out these roles effectively. The following cell types all have unusual shapes that are important for their function. 2. Stem cells are cells with the potential to develop into many different types of cells in the body. They serve as a repair system for the body. There are two main types of stem cells: embryonic stem cells and adult stem cells
Explanation:
Kidney cell is different from other cells in your body such that they are
involved in the following functions due to unique structures and
mechanisms present.
FiltrationIon homeostasisBlood pressure control.Stem cells are majorly involved in the repair of body cells and tissues
during injuries or when worn-out. This is as a result of them having the

Exercise cannot be sustained when anaerobic respiration takes place in muscle cells.
Explain why.
False. Exercise can be sustained when anaerobic respiration takes place in muscle cells, but in addition to aerobic respiration.
Exercise and anaerobic respirationAnaerobic respiration, also known as fermentation, can occur in muscle cells when there is not enough oxygen available to support aerobic respiration.
This process generates ATP by breaking down glucose without using oxygen. However, it is much less efficient than aerobic respiration and produces lactic acid as a byproduct.
Thus, in addition to aerobic respiration, anaerobic respiration in muscle cells can help sustain exercise.

The cell theory is a scientific explanation about the characteristics of cells in living things discovery of cells occurred in the 1600s which piece of equipment my students in science class used to investigate the cell theory
Answer:
Then, what is the question????
In 1665, Robert Hooke, a scientist published Micrographia, a book full of illustrations and descriptions of organisms observed under the recently invented microscope, hence Hooke's discovery of the cell was successful with the invention of the microscope.
What is Microscope?A microscope is defined as a laboratory instrument used to examine objects that are too small to be seen by the uncovered eye. Microscopy is the science of examining small objects and structures using a microscope. The word microscopic means invisible to the eye unless aided by a microscope.
Without the microscope, we would not know about the existence of cells or how plants breathe or how rocks change over time. Cell theory was discovered by Robert Hooke in 1665 with the help of a microscope.
