The picture above is an example of what type of tissue?
Answer: Epithelial Cell
Explanation:
The given picture above is an example of epithelial tissue. Option 3 is correct.
Epithelial tissue is a type of tissue that covers the outside of the body and lines the inside of organs and cavities. It is made up of tightly packed cells that form a continuous sheet. Epithelial tissue has many functions, including:
Protection: Epithelial tissue protects the body from harmful substances and pathogens.Secretion: Epithelial tissue secretes substances such as mucus, sweat, and tears.Absorption: Epithelial tissue absorbs nutrients and other substances from the environment.Excretion: Epithelial tissue excretes waste products from the body.There are four main types of epithelial tissue:
Simple squamous epithelium: This type of epithelium is made up of a single layer of flat cells. It is found in the lining of the blood vessels, lungs, and kidneys.
Simple cuboidal epithelium: This type of epithelium is made up of a single layer of cube-shaped cells. It is found in the lining of the kidney tubules and the small intestine.
Simple columnar epithelium: This type of epithelium is made up of a single layer of column-shaped cells. It is found in the lining of the stomach, intestines, and uterus.
Stratified squamous epithelium: This type of epithelium is made up of multiple layers of flat cells. It is found in the skin, the lining of the mouth, and the esophagus.

Is water an organic molecule? why or why not?
Answer:
Organic molecules associated with living organisms are also called biomolecules. Organic compounds are molecules that contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds). ... Water (H2O) has no carbon; then, it is not an organic compound.
During DNA replication, why is it that the entire molecule does not open at one go?
Answer:
DNA replication requires a very high energy. It has to be fast and accurate as well. Therefore instead of opening in one go, long DNA molecules of eukaryotes have a large number of replicons all of which work simultaneously.
Explanation:
While replicating, the entria DNA molecule to keep the whole molecule stabilised does not open in one go because it would be highly expens energetically. ... Actually , unwinding creates tension in the molecule us cucoiled parts start forming super coils due to the interaction of exposed nucleotides
Answer: Because it would be highly expens energetically
Explanation: unwinding creates tension in the molecule us cucoiled parts start forming super coils due to the interaction of exposed nucleotides .
The scatter plot shows a bus stop where those waiting at the bus are plotted by their height and by their age. Identify which dot goes with which passenger.
The scatter plot is a plot of age versus height of those at the bus stop, hence, identifying which dot goes with which passenger will require an assumption that age and height are positively correlated.
Davis is the smallest in height/age and thus, would be dot 7.Cathy is next to Gavis and thus, would be dot 6Dot 4 and 1 are approximately located at the same height. Looking at the image, only Brenda and Dennis have approximately the same height. Dennis is, however, far older than Brenda in age merely looking at the image. Thus, dot 1 would be Dennis while dot 4 would be Brenda.Next to Dennis and Brenda in height is Freda and that would be dot 3.Alice and Emmi are also approximately of the same height but Alice seems older than Emmi from the image. Hence, dot 2 would be Alice while dot 5 would be Emmi.From the analysis:
1 - Dennis
2 - Alice
3 - Freda
4 - Brenda
5 - Emmi
6 - Cathy
7 - Gavis

explain why oxygen and glucose need to be absorbed and waste products need to be removed
Explanation:
Oxygen and nutrients from food must be absorbed into the bloodstream to be delivered to cells for respiration. Waste materials such as carbon dioxide must be removed from cells into the bloodstream. Tissues contain capillary networks to allow these exchanges to occur at a cellular level.
Oxygen and glucose needs to be absorbed and waste products need to be removed for the proper functioning and maintenance of the body cells and systems.
Oxygen is an odor less and colourless gas that is needed by living organisms.
It is absorbed by living organisms because it serves as a source of fuel.
Glucose is a type of carbohydrate called monosaccharide which is gotten from food.
It is assimilated or absorbed into the body through the hormone insulin and serves as a source of energy.
Waste products of metabolism is removed from the body through the process of excretion. A typical example is the carbondioxide.
If Waste products are allowed to accumulate they cause poisoning which slows down vital chemical reactions.
