Can someone explain to me?

Answer:

Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.

Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.

Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.

Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.

Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.

Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.

Answer:

1.) Lactase is an example of ENZYME.

2.)An INHIBITOR is a molecule that can bind to an enzyme and prevent the enzyme from working.

3.)Enzymes speed up chemical reactions by lowering the ACTIVATION ENERGY,

4.) a molecule of SUBSTRATE binds to the enzyme and is broken down into one or more molecules of PRODUCT which are released.

5.) The specific location within an enzyme molecule where the substrate binds is called the ACTIVE SITE.

Explanation:

An enzyme is defined as the substances that aids in the breaking down of complex food substances, taken in by animals, into simple, soluble and diffusible substances before they can be absorbed into the body. In the enzymatic reactions, a molecule of SUBSTRATE binds to the ACTIVE SITE of an enzyme and is broken down into one or more molecules of PRODUCT which are released.

There are different types of enzymes which are named according to the type of good they digest, these include:

--> Lactase: breaks down Lactose

--> proteases: breaks down proteins

--> Amylases: breaks down carbohydrate

Enzymes have the following characteristics:

--> They are proteins

--> They are specific in action. For example Lactase can only act on lactose.

--> They can be inactivated by INHIBITORS.

--> They are sensitive to temperature

--> They speed up a reaction by lowering the ACTIVATION ENERGY

Answer:

Third parties are important in a political system because they serve an important role in our political system by forcing major political parties to address new issues they might not have previously addressed very much. And third party candidates can also greatly impact an election by taking away votes from one of the major political party candidates.

Answer: D. Kingdom Animal

Explanation: Among other animal characteristics, humans can move on their own, so they are placed in the animal kingdom. Further, humans belong to the animal phylum known as chordates, because we have a backbone. The human animal has hair and milk glands, so we are placed in the class of mammals.

Answer:

D. Kingdom Animalia

Explanation:

Human beings belong to kingdom Animalia. So, option (D) is correct.

Answer:

D.

Explanation:

You can rule out B and C because offspring produced sexually are not identical to their parents. The amoebas reproduce by binary fission, which is a form of asexual mitosis.

Answer:

D. asexually by the process of MITOSIS

Explanation:

Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA.

Answer:

yep, my explanation

Explanation:

you see, it is a very dirty cycle, when you have a dioploid cell, you have your typical duplication of sister chromotids, but producing sex cells or gametes which would become a zygote through dirty interactions come to form one dioploid cell and it will start doubling like the rest of the human body, until it comes out of the other human's body. meiosis, or the formation of gamates are created with a crossover where one diolpoid cell takes one half of the chromosome and the other half and exchange a tiny bit of it before splitting into 2 DIFFERENT gametes cells because of the cross-over and hence ther term natural selection

Explanation:

The earth receives unequal amount of light energy and heat energy form the sun. There is variation in the solar energy at different parts of the world due to factors like atmospheric circulation as well as the distribution of the land and the sea.

The main factors which results in the unevenly distribution of the heat and light from the sun to the earth are :

The sun provides more light and heat at the equatorial regions than the polar regions.

Answer:

A single round of DNA replication occurs in the parent cell, followed by two distinct nuclear division cycles. The process produces four haploid daughter cells, each with half as many chromosomes as the diploid parent cell.

Explanation:

During sexual reproduction, meiosis produces the sex cells that combine to make new children.

Meiosis is a type of cell division that results in the formation of sex cells (egg and sperm). And that is brought together to generate new progeny through the act of sexual reproduction.

Meiosis generally results in 4 haploid daughter cells, meaning half no chromosomes are contained in diploid cells.
