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.

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.

Describe an example of fermentation that occurs in beneficial bacterial cells within animals and explain why it is important.
Fermentation is an anaerobic process in which energy can be released from glucose even though oxygen is not available. Fermentation occurs in yeast cells, and a form of fermentation takes place in bacteria and in the muscle cells of animals. In these situations, your working muscles generate ATP anaerobically (i.e., without oxygen) using a process called fermentation. Fermentation is beneficial in that it can generate ATP quickly for working muscle cells when oxygen is scarce. Fermentation helps break down nutrients in food, making them easier to digest than their unfermented counterparts. For example, lactose — the natural sugar in milk — is broken down during fermentation into simpler sugars — glucose and galactose ( 20 ).
Microbial fermentation takes place within the gastrointestinal tract of the majority of the animals by the bacterial cells, this helps in the process of digestion and in the synthesis of certain essential components like vitamins.
• The enzymatic decomposition and the usage of food components, mainly carbohydrates by the help of microbes like bacteria anaerobically is termed microbial fermentation.
• Within the gastrointestinal tract of the majority of animals, the process of fermentation takes place, however, the intensity of fermentation depends on the quantity of bacterial cells present, which is usually greatest in the intestine.
• The process of fermentation within the intestine by bacteria primarily helps in the process of metabolism and digestion of carbohydrates that does not get digested in the small intestine like residual starch and cellulose.
• Apart from this, microbial fermentation also helps in the production of vitamin K and some B vitamins.
Thus, microbial fermentation within the intestine of the majority of the animals performs essential functions like digestion and production of vitamins.

What initially causes a nerve impulse? release of enzymes out of the neuron movement of chemicals into the dendrites of the neuron pathogens attacking the dendrites of the neuron red blood cells bathing the neuron
Answer:
movement of chemicals into the dendrites of the neuron
Explanation:
Nerve impulse occurs when electrical gradient is moved across the plasma membrane of a resting neuron this is done when the neuron receives a chemical signal from another cell or some other type of stimulus. This action potential then travels down the neuron’s axon as an electric current.
Resting potential occurs because of the difference in electrical charge across the plasma membrane of a neuron.
An electrical gradient is maintained by the sodium-potassium pump this is done across the plasma membrane of a neuron when it is not transmitting a nerve impulse this is the resting potential of the neuron.

_____inherited traits that increase an organisms chance of survival, also determine an organism’s niche.
Answer:
Adaptations are inherited traits that increase an organism's chance of survival, also determine an organism’s niche.
Explanation:
Adaptations can be defined as inherited traits that increase an organism's chance of survival and determine its niche. An organism's niche is the place it has in an ecosystem it inhabits - how it lives and survives in it and how it affects it and other species.
Adaptations are a necessary occurrence. As the organism's habitat changes, it has to change as well. In order words, it has to adapt. This process is supported by natural selection - the mechanism that ensures that an advantageous characteristic will become the most common one.
An example of adaptation is what an animal's teeth look like. The shape of an animal's teeth heavily depends on its diet. If it's a herbivore, it will have many molars for chewing grass and plants, and if it's a carnivore, it will have sharp canines to help it tear meat.

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.
