Answer:
In humans we go through Lactic Acid Fermination
Explanation:
It is important because after glycolysis we have the elctron carrier NAD+ reduced to NADH and we cant continue glycolysis until we have NADH back to NAD+ so all lactic acid fermintation does it removed the electron and allow glycolysis to continue. It should be noted that fermintation occurs when there is no oxygen / not enough to continue cellular respiration so we rely on glycolysis to produce very little ATP while oxygen is replenished,

Explanation:
The motion of the block is decreasing with the period of time. So, the correct option is (J).
What is Motion?
Motion is defined as when an object changes its position with respect to time. In other words, the act of moving or the process of being moved. It can be described in many words such as displacement, distance, velocity, acceleration, speed etc.
The motion in a long line or a curve is called as Translation whereas the motion which changes the orientation of the body is called Rotation. In both the cases, all the points in the body have same velocity (having speed with direction) and same acceleration which is defined as time rate of change of velocity.
Motions are of two types:
1. Translation
2. Rotation
Some examples of motions are running, cycling, swimming, eating, drinking etc. Motion is caused by force, when we apply a force motion occur.
Thus, the motion of the block is decreasing with the period of time. So, the correct option is (J).

What are the possible blood types of a baby with a mom who is heterozygous for blood type A and a dad with type O?
Answer:
A & O group
Explanation:
Dad will be having io io allele and mom will be having ia io
The possible blood types for the baby are either A or O, with equal likelihood of 50% for each.
What is blood type?A classification system called blood type explains whether or not specific antigens are present on the surface of red blood cells. Each of the four major blood types—A, B, AB, and O—has distinct antigen markers.
A and O are the two possible blood types for a child whose mother is heterozygous for blood type A (genotype AO) and whose father has type O (genotype OO).
A baby has a 50% chance of acquiring the A allele from the mother and a 50% chance of inheriting the O allele from the father because each parent gives one of their two blood type genes to their offspring.
Baby with blood type A inherits the A allele from the mother and the O allele from the father (genotype AO).
The child will have blood type O if both parents carry the O allele (genotype OO).
Therefore, the possible blood types for the baby are either A or O, with equal likelihood of 50% for each.

What is an algae?Algae is an informal term for a large and diverse group of photosynthetic eukaryotic organisms. It is a polyphyletic grouping that includes species from multiple distinct clades.
Moreover, algae are photosynthetic creatures. They are neither plant, animal or fungi. Many algae are single celled, however some species are multicellular. Many, but not all of red and brown algae are multicellular.
Therefore, algae are defined as a group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems, leaves, and specialized multicellular reproductive structures of plants.

What do you mean by cell division?Cell division is the process by which a parent cell divides into two daughter cells. Cell division usually occurs as part of a larger cell cycle in which the cell grows and replicates its chromosome before dividing.
There are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. Mitosis is a fundamental process for life.
In eukaryotic cells, or cells with a nucleus, the stages of the cell cycle are divided into two major phases: interphase and the mitotic (M) phase.

Most species of E. Coli are harmless or even helpful forms of bacteria that are found in the human intestine. E. Coli can aid humans in digestion and provide protection from other invading bacteria, but if the bacteria move to the human excretory system, they can replace other naturally occurring bacteria (Lactobaccilli). This can lead to bladder and kidney infections. Researchers found that by replenishing the excretory system with the naturally occurring bacteria, the infection caused by E. Coli is cured. Based on the research, what inference can researchers claim about the effect of bacteria?
Answer:
The inference is that bacteria can be pathogenic or characteristic of the commensal microbiota of different organs.
Explanation:
The human coexists with commensal micro-flora or commensal biota that are in balance and protect it from other pathogenic microorganisms, that is why we constantly live with a group of bacteria that do not generate pathological conditions in our body and even promote the stimulation of the immune response. .
When this balance is broken, pathogenic or opportunistic microorganisms invade, this is how they proliferate and generate infectious diseases that threaten the balance or state of human health.

1. digestive organs accesory organs
the organs that are directly involved the organs which helps the
in digestion like stomach, small intestine, digestive organs by thier
large intestine etc scretions or by other means like
liver ,pancreas etc
2. food bolts chyme
DIFFERENCES
the substance which The semi hard the soup like substance
is eaten by a person. substance
it is semi digested in it leaves oral cavity it leaves stomach and went to
oral cavity. and move to stomach small intestine
SIMILARITIES
They all are nutrients containing meterials which are to be digested. they all contain carbohydrates,protiens ,fats and vitamins (somehow if the food is taken from plant source) and they all are about to be absorbed.
3.DIGESTIVE SYSTEM:
the process in which food substance is broken into pieces and is converted into the simpler substances which can be assimilate by body cells. Different glands scretes digestive juices which digest fats,protiens ,carbohydrates etc e.g gastrin,bile,pancreatic juice and intestinal juice. and at the end all the product remain is excreted out after assimilation.
ORGANS INVOLVED: oral cavity,oesophagous,stomach small intestine ,large intestine.
4. salivary glands are damaged:
if salivary glands are destroyed or damaged then no saliva will produce to protect the walls of gut and the gut walls will be damaged by the acidic or basic juices of gut which will causes severe ulcer of oesophagous, stomach or intestinal.
5.CONSTIPATION:
when too much water is absorbed by the walls of large intestine so the end product which is to be excreted will become so hard that it is dificult to excrete 0it out of body.
CAUSES: it may be caused by hormonal disturbance ,water deficiency and may be by silliness of a person that he use to be silly to go to the bathroom at time.
6. INGESTION: Taking of food from the outside of the body from different means which contain nutrients essential for body growth.
DIGESTION: Breakdown of food into simpler substance which can be easily taken by body cells .
ABSORPTION:Large intestine and smaal intestine absorbs the certain amount of nutrients and water from the digested substance to fullfil the body deficiencies. These nutrients are then assimilated into the body.
EXCETION:the substance which remain after absorption is excreted out of the body from exterior opening called anus is called excretion.
Describe animal interactions that affect populations in the tundra ecosystem. (Please help please... I have already had a mental breakdown over school today because its getting harder and harder so please help!)
Answer:
Herbivorous animals are unable to feed and end up migrating to other regions in search of food.
Explanation:
The tundra is a type of vegetation composed almost exclusively of mosses and lichens. This type of vegetation is found in regions with a polar climate. It is important to note that the tundra has a very fast vegetative cycle. That's because it freezes quickly and can be covered with ice all winter. This ends up modifying the lives of some animals that feed on this vegetation. These animals end up with unavailability of food and need to migrate to others in search of food.

The trend shows that the Enzyme Pepsin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
Explanation:
You can tell by seeing the enzyme activity compared to the pH range. Enzymes are simply proteins which work around your body so pepsin since it is active in acidic levels (pH 2) is probably an enzyme found in the stomach.
The trend shows that the Enzyme Pep sin is active and prefers the pH level of 2. While Trypsin Is much active at pH 8 and prefers that pH level.
What are the functions of enzyme pepsin?Pepsin is an endo peptidase that breaks down proteins into smaller peptides. It is produced in the gastric cells of the stomach lining and is one of the main digestive enzymes in the digestive systems.
Pep sin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pep sin as an in active zymogen called pepsinogen.
In the digestive tract pepsin effects only partial degradation of proteins into smaller units called peptides, which then either are absorbed from the intestine into the bloodstream.
