Two organisms mate and produce infertile offspring. Which is a true statement about why it is not able to reproduce?
A. The parents are a different genus and species
B. The parents are a different species, but the same genus
Answer:
a
Explanation:
a is the correct answer
The statement which is true about why it is not able to reproduce is that the parents are a different genus and species. Thus, the correct option for this question is A.
What is Species?Species may be defined as the collection of organisms that can significantly reproduce with one another in nature and produce fertile offspring.
According to the context of this question, the process of speciation takes place when the members of similar populations no longer interbreed with one another in order to produce fertile offspring within their natural environment. So, the mating of two organisms can not produce fertile offspring until they belong to the same genus and species.
Therefore, the statement which is true about why it is not able to reproduce is that the parents are a different genus and species. Thus, the correct option for this question is A.

Which option describes a strong argument against the development of nuclear power? A nuclear power company is proposing a nuclear power plant near a quiet, small waterside town. The company is promoting this development by stating that nuclear power does not produce pollutants.
Answer:
The correct answer is B) The company is promoting this development by stating that nuclear power does not produce pollutants.
Explanation:
Whilst the process of power generation itself does not produce environmental pollutants like fossil fuels which features the emission of carbon monoxide when they are partially combusted, it does leave behind radioactive wastes, in the same way, combusted charcoal or wood leaves ash behind.
The challenge with radioactive wastes is that they are inimical to human health and can remain so for hundreds of centuries.

a student observed a food sample that’s left a greasy spot on paper and also gave a positive test for starch. which two organic compounds are present in the food sample ?
Answer:
The correct answer is - fats and carbohydrates are two organic compounds that are present in the sample.
Explanation:
The greasy spot present on paper shows that there are fats present in the food sample that can be butter, ghee, or oil. Fats are the organic compound that provides energy to the organism that eats fat, however, more than a limit fat is harmful to any person.
The starch test suggests that food samples have starch present in the sample, starch is nothing but a polymeric carbohydrate. Carbohydrate is a basic organic compound that provides energy to the body or different organism.
Thus, the correct answer is - fats and carbohydrates.

Are there any mammalian cells that would be a good source for dividing cells? What types of cells would most like NOT have cells undergoing division?
Answer:
Skin cells, bone cells
Explanation:
1. Skin cells are constantly being replaced, so it's likely they will be undergoing Mitosis.
2. Bones grow very slowly, and can last for years, which means that it's unlikely they will be undergoing mitosis.
There are a couple of mammalian cells that would be a good source for dividing cells. They include but not limited to:
The cells of the skinCells in the bone marrowThe cells of the skin adjacent to the environment are constantly being replaced by cell division due to death relating to environmental factors.
The cells in the bone marrow are also dividing constantly because old blood cells are constantly being replaced.
Some cells in the human body do not divide ordinarily, unless they are called upon to do so on special circumstances. For example, the cells of the heart stop dividing once the heart gets to a particular size. The cells enter the quiescent stage of the cell cycle and they are only called upon to divide in case an injury occur to the heart and it needs to repair itself.

Include an explanation of how the surface area-to-volume ratio, diffusion rate, and time for substances to reach the center are related. Support your explanation with data
Answer:
simple:

Farmers brought nutria, a type of large rodents, from South America to North America in the 1990s. They wanted to raise the rodents for their fur. Some of these rodents escaped into the wild and became a major pest in the Gulf Coast and Chesapeake Bay regions. Grasses and shrubs in these regions are vital, because they provide food and shelter for many species. They also help in preventing soil erosion. The nutria are eating up all the grasses and shrubs, which affects the food cycles of these regions. The entire ecosystems are being disrupted.
Moreover, nutria pose a direct threat to humans. These rodents are an effective vector for carrying parasites that can cause disease in humans. They also damage property. The burrows created by nutria can damage dams and building foundations as well as cause erosion near streams and lakes.

the answer from pluto/edmentum
Answer:
The apple snail is a native species of Argentina, Bolivia, Brazil, Paraguay, and Uruguay. Southeast Asia legally imported this alien species to use it as a protein source. Later, this species was brought to places like Hawaii as a source of food.
Like most, if not all, invasive species, the apple snail outcompetes native species for resources. This is because it reproduces rapidly (laying hundreds of eggs every few weeks) and lacks predators. As a result, the snails spread rapidly to aquatic biomes and modify the natural balance of aquatic ecosystems.

How many atoms in all are in a molecule of serotonin?
Answer:
10 carbon (black), 12 hydrogen atoms (white), 2 nitrogen atoms (blue), 1 oxygen atom (red)
Explanation: Serotonin is a molecole composed of all of these atoms
A molecule of serotonin has 25 atoms in total, and these atoms are arranged in a specific pattern to give serotonin its unique chemical and biological properties.
What is serotonin?Serotonin is a neurotransmitter, which means it is a chemical that is used by the nervous system to transmit signals between nerve cells. It is also a hormone that regulates various physiological processes in the body. The chemical formula for serotonin is [tex]C_1_0H_1_2N_2O,[/tex] which indicates that it contains 10 carbon atoms, 12 hydrogen atoms, 2 nitrogen atoms, and 1 oxygen atom. The molecule of serotonin consists of a benzene ring with two substituents: an amino group and a hydroxyl group (-OH). The amino group and hydroxyl group are attached to adjacent carbon atoms in the benzene ring, and the nitrogen atom is attached to one of the carbon atoms in the amino group.
Hence, a molecule of serotonin has 25 atoms in total, and these atoms are arranged in a specific pattern to give serotonin its unique chemical and biological properties.
