Answer:
Electron Microscope
Explanation:
The maximum theoretical resolution of images created by light microscopes is ultimately limited by the wavelengths of visible light. Most light microscopes can only magnify 1000×, and a few can magnify up to 1500×, but this does not begin to approach the magnifying power of an electron microscope (EM), which uses short-wavelength electron beams rather than light to increase magnification and resolution.
-The electron microscope can achieve a much greater resolution than that obtained with the light microscope because the wavelength of electrons is shorter than that of light.
An Electron microscope is the type of microscope that would be the best tool to use to view the surface of a bacterial cell.
What is a Microscope?A microscope may be defined as an instrument that utilizes the arrangements of lenses to make an enlarged image of a small object.
An Electron microscope produces a higher resolution of bacterial cells as compared to a standard light microscope. This is because electrons possess a much shorter wavelength than visible light.
Therefore, the correct answer to this question is an Electron microscope.

If the study on the relationship between W. bancrofti and Wolbachia is correct, then combined with the results of the trials, significant numbers of microfilariae do not survive in circulation beyond what time period
Answer:
6 months
Explanation:
First, we must remember that doxycline has an effect only on nematodes, but it cannot effectively prevent microfilariae presented before treatment in the blood of the infected. What we can conclude from this is that it is possible that microfilariae grow and develop, however they will not be able to reproduce, since W. bancrofti is completely dependent on Wolbachia for replication. With that, the microfilariae are running out of time and with about 6 months the patients are free of any trace of microfilariae. So we can conclude that 6 months is the longest time that microfilariae survive in circulation.
Can podocyte cells in the Bowmann capsule attach to any other basement membrane other than the glomerular basement membrane? That is, it can itself have a separate layer of base membrane?
Answer:
"Podocytes are cells in the Bowman's capsule in the kidneys that wrap around capillaries of the glomerulus. Podocyte cells make up the epithelial lining of Bowman's capsule, the third layer through which filtration of blood takes place.[1] The Bowman's capsule filters the blood, retaining large molecules such as proteins while smaller molecules such as water, salts, and sugars are filtered as the first step in the formation of urine. Although various viscera have epithelial layers, the name visceral epithelial cells usually refers specifically to podocytes, which are specialized epithelial cells that reside in the visceral layer of the capsule.

Endometriosis occurs when endometrial tissue, which normally grows inside the uterus, grows outside the uterus. Based on the model, what effects would you expect these growths to have on the female reproductive system and on fertility?
Answer:
Endometrosis could negatively affect the probability of gestating an embryo if they are growing inward. The affection of the fallopian tubes and the uterus could alter the implantation or even generate complications for the embryo during pregnancy.
In addition, endometriosis generates painful conditions in the abdominal area to the point that it is considered as menstrual cramps during menstruation, women who suffer from this disease suffer a lot during the menstrual cycle.
Regarding the reproductive system, those female reproductive systems that suffer from this disease are considered potentially malignant, since many malignant neoplasms are incited to appear in these foci of excessive proliferation of the endometrium.
Explanation:
Endometriosis can affect the walls of the fallopian tube and the uterus, since it occurs in the endometrium, that is why it bears that name.
The macroscopic appearance of this lesion at the histological level is a tumor nodule, since they are proliferative foci.
Answer:
abnormal tissue growing on the ovaries might affect ovulation, making it harder or impossible for women to get pregnant. The extra tissue may cause pain, since the tissue is growing in places it is not meant to be growing

Answer:
shoulda used ziploc?
Explanation:
Answer:
Hypotonic
Explanation:
When sugar is dissolved into the water, it adds molucules, making the water have a higher concentration. If you have a semipermable membrane between the two, it would create a process called osmosis. The hydrogen bonds would all go to the side with the higher concentration side, also known as the hypertonic side. The side with less bonds would be called the hypotonic side.

A. This enzyme works equally well at all temperatures.
B. This enzyme works best at 10 degrees Celsius.
C. This enzyme works best at 45 degrees Celsius.
D. This enzyme works best at 60 degrees Celsius.
The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.
What are the factors affecting enzyme activity ?The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes
The rate also increases with increased enzyme concentration up to the saturation point
Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.
The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by forming a loose complex and inhibits the activity of enzymes.
Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.
water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.

Sebastian wants to make ball-and-stick models of the four macromolecules. He has colored balls for each of the elements in these molecules, including the following. red: hydrogen black: carbon purple: oxygen green: nitrogen Which molecule could he make that consists of long chains of red and black colored balls? carbohydrates lipids nucleic acids proteins
Answer:
lipids
Explanation:
There are four major biological macromolecules in living systems viz: carbohydrate, proteins, lipids and nucleic acids. These macromolecules play a significant role in the optimal functioning of every living organism. Like every other polymer, these macromolecules are made up of simpler units called monomers that defines their chemical structure. In turn, the monomers consists of chains of chemical elements held together.
According to the question, Sebastian has colored balls that represents the elements contained by each of these macromolecules. The colored balls and the elements they represent are as follows: Red: hydrogen, Black: carbon, Purple: oxygen, and Green: nitrogen.
Lipids are structurally made up of fatty acids and glycerol, which are long chains of carbon and hydrogen elements with a relatively small percentage of oxygen in the structure. An example is palmitic acid, which has a structural formula: CH3(CH2)14COOH
Hence, Sebastian could make a LIPID macromolecule, which consists of long chains of red (hydrogen) and black (carbon) balls since lipids are mostly made up of carbon and hydrogen elements in their structure.
Carbohydrates are composed of more percentage of oxygen in their structure. Hence, a long chain of only red (hydrogen) and black (carbon) balls cannot make them. Proteins and nucleic acids are made up of additional nitrogen and phosphorus elements in their structure.
Answer:
B. Lipids

Plants respond to changes in their environment. They detect gravity, light, touch, and seasonal changes, and respond to these stimuli in many ways. Which statement best explains this flexibility in response? A) Phenotypes are controlled by one gene that codes for multiple regulatory proteins. B) The genes that regulate plant responses can be expressed in different ways. C) The genes that regulate plant responses can mutate to adjust to environmental changes. D) Phenotypes control the genotypes of individuals, determining plant responses.
Answer:
B)
Explanation:
Plants have the ability to detect the changes in their environment and respond accordingly. Plants' responses to stimuli is due to the genes that regulate plant responses can be expressed in different ways.
Genes code for hormones and support transport of hormonal synthesis in plants. Plants hormone such as auxin promotes different changes in plant growth in response to light, gravity, touch or seasonal changes and the auxin respond due to transport inhibitor response 2 gene.
Hence, the correct answer is "B".

When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. When fats are used as an energy source, the glycerol portion enters ________ when it has been converted to ________. glycolysis; dihydroxyacetone phosphate the electron transport system; coenzyme Q glycolysis; fructose-6-phosphate the citric acid cycle; pyruvate the citric acid cycle; acetyl CoA
Answer:
glycolysis; dihydroxyacetone phosphate
When fats are used as an energy source, the glycerol portion enters the glycolysis when it has been converted to dihydroxyacetone phosphate. Thus, the correct option is A.
What is the Glycolysis?Glycolysis may be defined as the process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen.
In order to obtain energy from fats, triglycerides must be broken down into fatty acids and glycerol through hydrolysis. The fatty acids enter to Krebs cycle and are converted into acetyl CoA.
While the glycerol portion enters into glycolysis and is converted into dihydroxyacetone phosphate.
Therefore, the correct option for this question is A.

how do i explain assimilation of glucose, amino acid and lipid?
Assimilation simply means the ways by which some of the food we eat and are absorbed by the body are being converted to new protoplasm or used to provide new energy for the body.
ASSIMILATION OF GLUCOSE
The hepatic portal vein transports absorbed sugars to the liver,the excess glucose is then converted to glycogen by insulin.When needed by the body,the liver in-turn converts this glycogen to glucose so that they can be moved to the cells,from there glucose is transported to every other parts of the body so that they can provide the cells with needed energy,during cell respiration,glucose is oxidized to release energy to be used for vital activities.
ASSIMILATION OF AMINO ACIDS.
Amino acids which are end products of protein passes through the liver to all parts of the body.
When amino acids are excess in the body,they will be deaminated in the liver to form urea, amino acids aren't stored,they are used to make proteins,repair worn out cells, aids growth, formation of enzymes and hormones and conversion into new protoplasm.
ASSIMILATION OF LIPIDS
Lipids which are end products of fats and oils are transported by the lymphatic capillaries or lacteal.
When lymph comes together with fat, chyle is formed,this chyle will further be discharged into the bloodstream and will be carried by the blood.
Fats are used to alternate source of energy for the body and as well form new protoplasm like the cell membrane.
When fats are in excess,they are stored in the adipose tissue which are found around the heart, kidneys, beneath the skin,and mesenteries that binds the intestines.

How are the proteins inside your body affected by the presence of water and other molecules?
Answer:
Our body is constitute of several essential molecules such as proteins, fat, carbohydrate, water, and other molecules.
Each molecule has some of the impact of other molecules in the body. Impact of water and other molecules on proteins inside the body are as follows:
Proteins have ligand-binding site and water provide stability to the ligand-binding site of proteins through its hydrogen bonds.Conformational flexibility and transitions of proteins are due to the presence of water molecules in it.Disbalance in the pH of body due to changing concentration of sodium-potassium ions can denature the protein. Enzymes present in the body can control the rate of formation of proteins in the body.
