Answer: Opposite charges attract one another. The slight positive charges on the hydrogen atoms in a water molecule attract the slight negative charges on the oxygen atoms of other water molecules. This tiny force of attraction is called a hydrogen bond. This bond is very weak.
Answer:
Negative
Very small charge in water.
What is the most important influence of the forest ecosystem on the environment
Answer:
Forests
Explanation:
Forests have also sanitary influences upon environment due to the production of oxygen through photosynthesis.
The study of the environment is called ecology. There are two types of factors for an ecosystem and these are a biotic and abiotic factors.
The correct answer is light
What is photosynthesis?The process of the formation of food by trapping the sunlight with the help of chloroplast is called photosynthesis.
According to the question, the most influential factor which affects the environment is light as all the plants directly depend on the light for the formation of food and all the other species are dependent on plants either directly or indirectly.
Hence, the correct answer is light.

cell-mediated immunity
O antibody-mediated immunity
Answer: both cell-mediated and antibody-mediated immunity.
Explanation:
Specific immunity involves targeting certain infections. This is done when certain cells assess the danger and release anti-bodies that target the antigens of the organism.
Once this is done, white blood cells will now be able to fight the organism or pathogen more efficiently.
There is therefore both a cell-mediated and antibody-mediated response.
Self-portraits can help you learn about positioning people in a photograph.
True
False
A camera's self-timer takes a picture after a certain amount of time has passed.
True
False
1.) True
The reason this is true is because adjusting the camera allows you to get an understanding of how someone else should look or how they would likely look best when photographed. It also gives an understanding of how a camera should be aimed to get the best result.
2.) True
While many cameras have this feature, most are configured to only use this feature when the photographer selects it. This feature allows the photographer to adjust the camera in case they feel something isn't quite right with it, and it also allows them to get into the picture themselves if they feel they want to.
Hope this helps you, and have fun with whatever it is you are doing with your camera.

In polygenic inheritance, each of the genes controlling a trait will have exactly the same influence over the trait. Group of answer choices Yes since all genes having to do with a trait always have the exact same influence on a trait. No since different genes will exert varying degrees of influence on the trait None of the other responses are satisfactory answers. No since all traits are only controlled by one gene with two alleles.
Answer:
No, since different genes will exert varying degrees of influence on the trait
Explanation:
The term quantitative heritability refers to the transmission of a phenotypic trait in which expression depends on the additive effect of a series of genes.
Polygenic heritability occurs when a trait results from the interaction of more than one gene. And these genes can also have more than two alleles. The action of many genes and alleles can cause many different combinations that are the reason for genotypic graduation.
Quantitative traits are those that can be measure, such as longitude, weight, eggs laid per female, among others. These characters do not group individuals by any precise and clear categories. Instead, they group individuals in many different categories that depend on how the genes were intercrossed and distributed during meiosis. The result depends on the magnitude in which each allele contributes to the final phenotype and genotype. When they interact, they create a gradation in phenotypes, according to the level of contribution.
Let us see, for instance, the eye color trait, which results from the interaction of many genes. Two of them significantly contribute to the color green, blue, or brown, while the rest of the involved genes play a role in defining the spectrum of phenotypes of each eye color. So, there are different tones of blue eyes, green eyes, and brown eyes, and the differences are determined by the contribution of each allele to the phenotype.

What kind of energy transformation is taking place in the plant in the
photograph?
O A. Potential energy → Nuclear energy
B. Solar energy - Chemical energy
C. Potential energy - Kinetic energy
D. Chemical energy → Solar energy
Based on the terms provided, the energy transformation taking place in the plant in the photograph is: Solar energy → Chemical energy This is because plants undergo a process called photosynthesis, where they convert solar energy (sunlight) into chemical energy stored in glucose molecules. The correct option is B.
What is the energy transformation?The transformation of energy from one form to another is known as an energy transformation. Every second of the day, energy is transformed somewhere. Energy can be expressed in a variety of ways, including electrically, thermally, nuclearly, mechanically, electromagnetically, sonically, and chemically.
The process of photosynthesis is taking place. The plant is converting solar energy (from the sun) into chemical energy in the form of glucose (sugar). This is an example of a transformation from one form of energy (solar) to another (chemical).
Therefore, the correct option is B.

The gram-negative bacterium Vibrio cholerae produces a protein, cholera toxin (Mr 90,000), that is responsible for the characteristic symptoms of cholera: extensive loss of body water and NaCl through continuous, debilitating diarrhea. If body fluids and NaCl are not replaced, severe dehydration results; untreated, the disease is often fatal. When the cholera toxin gains access to the human intestinal tract it binds tightly to specific sites in the plasma membrane of the epithelial cells lining the small intestine, causing adenylyl cyclase to undergo prolonged activation (hours or days).
a. What is the effect of cholera toxin on [cAMP] in the intestinal cells? Why?
b. Based on the information above, suggest how cAMP normally functions in intestinal epithelial cells. Briefly justify.
c. Suggest a possible treatment for cholera
Answer:
a.) It causes prolonged activation of adenylyl cyclase which leads to increased levels of Cyclic adenosine monophosphate(cAMP).
b.) In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.
C.) Cholera can effectively be treated through the use of antibiotics and intravenous fluid replacement therapy.
Explanation:
Vibrio cholerae is a gram negative rigid curved bacillus that are actively ( vigorously) motion by a polar flagellation. The name vibrio is derived from the characteristic vibration movement of the organism when viewed under a microscope. This bacteria is capable of producing toxins called cholera toxin, which it uses as a virulent factor. It is responsible for the characteristic symptoms of cholera: extensive loss of body water and NaCl through continuous, debilitating diarrhea.
Cyclic adenosine monophosphate(cAMP) which is called a second messenger because it is not a hormone that can directly institute an intracellular change, instead, it serves as a second messenger to cause an effect.In the intestinal epithelial cells, the cAMP binds to the apical chloride channels and allows it to open leading to osmotic permeability of water across the cell into the lumen of the intestine which is excreted through the faeces.
In the effect of cholera toxin on the cAMP in the intestinal cells, Cholera toxin increases the fluid loss. The binding of the toxin to the intestinal cells causes a large increase in the level of cAMP in the cells by inhibiting the conversion of GTP bound to Ga to GDP. So adenyl cyclase is not turned off and diarrhea results.
The possible treatment is through the use of antibiotics and intravenous fluid replacement therapy. Prompt and adequate replacement of lost fluid and electrolyte through oral administration and supplemented with intravenous administration of fluids highly suggested for treatment of cholera. Antibiotics is equally used for treatment only when the cholera strain has been confirmed sensitive to it through culture.
