Explanation:
Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.
A microbiologist is in the process of classifying a newly discovered organism. Its characteristics include: · eukaryotic · multicellular · reproduces by spores · motile in some stage of its life cycle · decomposer Which type of organism is it most likely to be? club fungus fungus-like protist plant-like protist sac fungus
Answer:
fungus-like protist
Explanation:
A fungus mostly has those characteristics. Most of them are multicellular eukaryotes -- the exception being yeast, which are unicellular eukaryotes. They can reproduce by spores and are decomposers; they even consume via absorptive feeding!
First, it's definitely not plant-like, as it is a decomposer, and there is no indication that it can produce its own food. It doesn't entirely seem like a fungus either, so the answer is a fungus-like protist.

Which of the following statements is true about the life cycle of animals?
a. The gametes are the diploid phase of the life cycle.
b.The gametes are the haploid phase of the animals life cycle.
c. Meiosis is not a necessary component of the animal life cycle.
d. The products of the haploid phase of the life cycle are larger than those of the diploid phase.
Among the given options, statement b. "The gametes are the haploid phase of the animal's life cycle" is true.
In the life cycle of animals, the gametes (sperm and egg cells) are the reproductive cells involved in sexual reproduction. Gametes are produced through a specialized cell division called meiosis, which reduces the chromosome number by half, resulting in haploid cells.
During sexual reproduction, haploid gametes from two parents combine to form a diploid zygote, which then develops into an organism. The zygote undergoes mitotic cell divisions, growing into a multicellular organism, and the diploid phase of the life cycle begins.

if carbon were to leave the plant which process would allow for that to happen
If carbon were to leave the plant, it could happen through the process of respiration or through transpiration.
Respiration is the process by which living cells use oxygen to break down carbohydrates and release energy. During respiration, carbon dioxide is produced as a waste product and released into the atmosphere. In plants, respiration occurs in both the leaves and roots, and it is necessary for providing energy for growth and other metabolic processes.
Transpiration is the process by which plants lose water vapor through tiny pores called stomata on the surface of leaves. During transpiration, carbon dioxide is exchanged for oxygen as part of the plant's normal gas exchange process. If the rate of transpiration is high and the plant is not taking in enough carbon dioxide to compensate, carbon could potentially leave the plant in the form of carbon dioxide gas.

EM waves that responsible for the food production of plants through photosynthesis?
Answer:
Visible light
Explanation:
Electromagnetic waves are formed from a combination of electrical and magnetic effects. Depending on the wavelengths, there are various waves in the EM waves. One of these waves ranging from wavelength 400-700nm is called VISIBLE LIGHT.
The chlorophyll pigments of plants, which enable them perform the process of photosynthesis, are only able to absorb the visible light of EM waves i.e. light ranging from blue to far red. Hence, VISIBLE LIGHT is the EM wave that is responsible for food production of plants through photosynthesis.
The electromagnetic wave that is important in food production of plants through photosynthesis is visible light.
The electromagnetic spectrum is composed of several waves that have different frequencies and wavelengths. However, the region of the electromagnetic spectrum that lies between 380 to 700 nanometers produce sensations that can be detectable by human eyes hence they are called visible rays.

In Klingons, eye color is a monogenictrait, meaning that the trait is determined by only one gene. The Father is homozygous recessive for eyecolor (bb) while the mother is heterozygous (Bb). Assume that brown eye color is dominant. Completethe Punnett Square below and determine the genotypic and phenotypic ratios.BbbA. What is the Genotypic ratio?B. What is the Phenotypic ratio.In other words, what are the odds that the mother's child willhave brown eyes?
Bb - mother is heterozygous for brown eyes
bb - father is homozygous recessive for yellow eyes
If Bb x bb are crossed, the following offspings are:
A. Genotypes are Bb - 50% and bb - 50%
Genotypic ratio is 1:1 since both offspings are 50 %
B. Phenotypes are Bb - heterozygous for brown eyes - 50% and bb - homozygous for yellow eyes - 50% or B-25% for brown eyes and 75% for yellow eyes
Phenotypic ration is 1:1 since both offspings are 50% or 1:3 B-brown eyes -25%, b-yellow eyes-75%
The possibility that the mother will have a child with brown eyes is 25% from the Bb which is heterozygous for brown eyes.

How does carbon not get lost when it moves through the carbon cycle
Answer:
Carbon is the chemical backbone of life on Earth. Carbon compounds regulate the Earth’s temperature, make up the food that sustains us, and provide energy that fuels our global economy. Carbon moves from one storage reservoir to another through a variety of mechanisms. For example, in the food chain, plants move carbon from the atmosphere into the biosphere through photosynthesis. They use energy from the sun to chemically combine carbon dioxide with hydrogen and oxygen from water to create sugar molecules. Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle. The ocean plays a critical role in carbon storage, as it holds about 50 times more carbon than the atmosphere. Two-way carbon exchange can occur quickly between the ocean’s surface waters and the atmosphere, but carbon may be stored for centuries at the deepest ocean depths. Rocks like limestone and fossil fuels like coal and oil are storage reservoirs that contain carbon from plants and animals that lived millions of years ago. When these organisms died, slow geologic processes trapped their carbon and transformed it into these natural resources. Processes such as erosion release this carbon back into the atmosphere very slowly, while volcanic activity can release it very quickly. Burning fossil fuels in cars or power plants is another way this carbon can be released into the atmospheric reservoir quickly.Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. As a result, the amount of carbon dioxide in the atmosphere is rapidly rising; it is already considerably greater than at any time in the last 800,000 years. The ocean absorbs much of the carbon dioxide that is released from burning fossil fuels. This extra carbon dioxide is lowering the ocean’s pH, through a process called ocean acidification. Ocean acidification interferes with the ability of marine organisms (including corals, Dungeness crabs, and snails) to build their shells and skeletons.
