why are living organisms classified?
Answer: See explanation
Explanation:
An organism refers to a living thing which can react to stimuli, move, grow, has an organized structure, reproduce, and can adapt.
Living organisms can be classified into kingdom, phylum, classes etc. The reason the classification of living organisms include:
1. Gives information about diversity of living organisms.
2. Easy identification of the organisms
3. Shows inter-relationship among the organisms.
4. Helps in understanding the evolution of the living organisms.
living organisms are classified so that it becomes easier for us to examine or study organisms

Describe hydrophobic interactions, the conditions under which they occur, and the probable influence they have on protein structure. Group of answer choices These are nonpolar side chains of amino acids that tend to associate to form hydrophobic clusters usually away from the protein surface. These are nonpolar side chains of amino acids that tend to destroy hydrophobic clusters away from the protein surface. These are polar side chains of amino acids that tend to associate to form hydrophobic clusters usually close to the protein surface. These are polar side chains of amino acids that tend to destroy hydrophobic clusters close to the protein surface.
Answer:
Nonpolar side chains of amino acids tend to associate to form hydrophobic clusters usually away from the protein surface.
Explanation:
Hydrophobic interactions are defined as the relationship between the low water soluble molecules named hydrophobes and water. They contains a long chain of carbon atoms and are usually considered as a nonpolar molecules.
They occur when the non polar amino acids are associated to produce the hydrophobic clusters that are usually away from the surface of the protein.
The point in a eukaryotic cell cycle at which DNA condenses to from visible chromosome?
Answer:
Prophase
Explanation:
There are different stages in the eukaryotic cell cycle. Different cellular occurrences are found in each of this stages. The stages include; prophase, metaphase, anaphase, telophase etc.
Prophase, which is the first division stage, is characterized by the dissociation of the nuclear membrane, tightening of DNA coils called chromatin by condensin proteins (condensation) to form X shaped visible chromosomes.

In an animal, which part of the cell is responsible for keeping viruses out?
Answer:
here's your answer
Explanation:
Once attached to a host cell, animal viruses may enter in a variety of ways: by endocytosis, where the membrane folds in; by making channels in the host membrane (through which DNA or RNA can be injected); or, for enveloped viruses, by fusing with the membrane and releasing the capsid inside of the cell.In an animal cell, the lysosome is an organelle of the cell that is responsible for destroying the virus. The virus can enter the cell via endocytosis, but the lysosome can degrade and destroy it to protect the cell.
What is the function of the immune cell?Immune cells such as neutrophils, macrophages, and others play a role in protecting the body from foreign harmful pathogens. They have specific structures for doing so.
Because not all body cells have MHC II or toll-like receptors, cells have different organelles to protect themselves. Cells have lysosomes within them. Lysosomes have an acidic environment that can degrade viral proteins.
When the virus is phagocytosed by the cell, it combines with the lysosome. The lysosome degrades the virus with the help of hydrolyzing enzymes and throws it out of the cells. These are collected by other cells.
Hence, the lysosome of the cell degrades the virus and keeps it out.

Which motion of particles across a membrane requires energy?
from high concentration to low concentration
from low concentration to high concentration
with no concentration gradient
through dynamic equilibrium
Answer:
B
Explanation:
Edge 2021
The motion of particles across a membrane from low concentration to high concentration requires energy. This process is called active transport. So, the correct option is B.
What is Active transport?Active transport, which requires energy in the form of ATP (adenosine triphosphate) or another energy source, is the movement of particles or molecules across a membrane from a region of low concentration to an area of high concentration, against the concentration gradient.
Numerous cellular functions, including the absorption of nutrients and the elimination of waste materials, depend on this mechanism. The sodium-potassium pump and the proton pump are two examples of active transport since they both employ ATP to move ions across cell membranes.
Therefore, the correct option is B.

If the gene sequence of DNA is A T T C G A C T C G what will the complementary mRNA sequence be that is made during transcription?
Answer:
U A A G C U G A G C
Explanation:
The complementary bases in RNA are the same as DNA with G-C (guanine to cytosine).
But, they are different in that RNA has A-U (adenine to uracil) instead of A-T (adenine to thymine).
Using these RNA base pairs of G-C and A-U, create the complementary mRNA sequence:
A T T C G A C T C G
Translate:
U A A G C U G A G C
So, the complementary mRNA sequence will be U A A G C U G A G C
What type of selection occurs when individuals
with traits at either extreme have higher
fitness than those individuals in the middle?
A. directional
B. stabilizing
C. disruptive
Disruptive type of selection occurs when individuals with traits at either extreme have higher fitness than those individuals in the middle. Hence option c is correct.
Natural selection happens when people with a particular genotype have a higher chance of surviving, reproducing, and passing on their alleles to the following generation than individuals with a different genotype.
When those at the upper and lower extremities of the curve are more fit than people in the middle, disruptive selection takes place. Disruptive selection targets people of an intermediate type, and it can result in the emergence of two different phenotypes.
African seed cracker birds' various beak sizes show evidence of disruptive selection. The beaks of the birds vary in size, and they eat seeds. There were two different sizes of seeds available: tiny and large.

What process facilitates locomotion for the ovum?
Question 6 options:
a. Once the ovum leaves the ruptured follicle it is captured by the uterus and then directed into the Fallopian tube, where it is pushed along towards the oviducts.
b. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
c. Once the ovum leaves the ruptured follicle it is fully matured and propels itself into the Fallopian tube, where it moves along towards the uterus.
d. Once the ovum leaves the ruptured follicle it is captured by the cervix and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
The correct answer is B. Once the ovum leaves the ruptured follicle it is captured by the fimbriae and then directed into the Fallopian tube, where it is pushed along towards the uterus via cilia.
Explanation
Ovulation is a process that occurs during the menstrual cycle that occurs around day 14 of the cycle. In the ovulation process, the eggs go through different places before reaching the uterus (their final destination). The first step is when the egg leaves the broken follicles. The second step is when it is taken to the fallopian tubes (place where fertilization occurs) through the fimbriae. The third step is when the egg uses the cilia to reach the uterus.
