3. Neutron goes to b

Question 4:Protons are a type of subatomic particle with a positive charge. ... Protons and neutrons have approximately the same mass, but they are both much more massive than electrons (approximately 2,000 times as massive as an electron). The positive charge on a proton is equal in magnitude to the negative charge on an electron

Question 5:Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you. ... The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus.

Question6:Thomson's model of the atom in 1897 shows that the atom was a sphere of matter, wherein the electrons are mixed inside it. This model does not show the protons and the neurons. On the contrary, the current model that was proposed by Niels Bohr gives us a clearer representation of the structure of an atom.

Choose a meat product that you eat, and construct a food chain that includes you as the final
consumer.

Answers

Typical meats include beef, chicken, turkey, and pork. Even though pigs are omnivores, all of these animals are mostly herbivorous.Animals find food along a single path, creating a feeding chain.

What is a Food Chain List?The way each living thing obtains its food is shown by a food chain. Some animals eat vegetation, while others prey on other creatures.For instance, a straightforward food chain connects trees and bushes, giraffes (who consume trees and shrubs), and lions (that eat the giraffes).It's a cliché that we've all heard thousands of times, whether to defend how we treat other animals or just to celebrate a carnivorous lifestyle: humans are at the top of the food chain.Each link in this chain provides food for the next link.However, ecologists have developed a statistical method for determining a species' trophic level—its position in a food chain.

Butterflies eat flowers on plant ,plants eaten by goat and goat is eaten by human beings as meat.

Where are people located in the food chain?

The apex of the food chain includes carnivores like polar bears and orca whales, which are not themselves preyed upon. According to recent research, we actually fall between between pigs and anchovies. With polar bears and orca whales at the top of the food chain, that places humans directly in the middle of the chain.

To create a food web, write out the primary producers, herbivores, omnivores, and carnivores for the chosen habitat. Connect them with arrows showing both predator and prey.

Sea anemones are predatory invertebrates with stinging tentacles that can paralyze many sea animals. The clownfish is immune to the sting of the sea anemone and actually lives among its tentacles. The relationship is mutually beneficial—the clownfish often lures meat-eating animals over to the anemone, and the anemone benefits from the meal. The clownfish often gets to eat leftovers from the anemone’s meal.

When the clown fish is ready to lay eggs, it lays them near a sea anemone. How’s this a reproductive strategy?

Answers

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.

By laying their eggs in close proximity to the sea anemone, the clownfish provide their eggs with a safe place to develop. The sea anemone's tentacles are a powerful defense mechanism that can fend off potential predators that may try to harm or eat the eggs.

In addition to protection, the clownfish also benefit from the relationship with the sea anemone during the reproductive process. The anemone provides a clean surface on which the eggs can be attached and also helps to oxygenate the surrounding water, which is important for the development of the eggs.

The anemone's tentacles also help to keep the eggs free of harmful parasites and fungi. Overall, the clownfish's reproductive strategy of laying eggs near a sea anemone is a mutually beneficial relationship that helps to ensure the survival of the clownfish offspring.

The protection and benefits provided by the sea anemone help to increase the chances of the eggs hatching successfully, resulting in a higher survival rate for the next generation of clownfish.

2. Normal woman does not show and breast discharge, what could be the reason in this patient for breast discharge?

Help me answer to your best of ability

Answers

Answer:

The correct answer is -

1. galactorrhea or prolactinoma

2. hormonal imbalance (prolactin imbalance)

Explanation:

The given symptoms experienced by the patient are the absence of menstrual cycles, an increase in weight, some milky discharge from her left breast, and abnormal facial hairs. The pregnancy tests show she is not pregnant and she also does not experience cold intolerance, dry skin, depression, fatigue or hot flushes.

All these suggest that there is a hormonal imbalance in her and due to producing a white substance from the breast it can get that there is too much production of prolactin, which suppresses the effect of estrogen, which is producing by the pituitary gland.

Galactorrhea or prolactinoma are two disorders that affect the production of prolactin that cause milky discharge, it can be caused by overuse of contraceptives or underlying conditions.

Environmental factors can influence natural selection because they can increase or decrease
the number of chromosomes in an individual.
the number of chromosomes in a population.
the amount of genetic variation in an individual.
the amount of genetic variation in a population.

Answers

Answer:

Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.

Explanation:

Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.

The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.

The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.

The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection

Hii! (: The correct answer is D. the amount of genetic variation in a population.

For a dominant/recessive trait, do the offspring of identical parents always look like the parents?

No, they don't always look like the parents.

Explanation:

They won't always look like the parents because from each parent, they will receive different dominant and recessive traits. In addition, certain traits skip generations or don't get passed down.

In terms of genetics and genomics, cloning refers to the use of scientific techniques to create exact or nearly exact duplicates of an organism, cell, or DNA sequence.

Thus, In most cases, the term "molecular cloning" refers to isolating and duplicating a specific DNA segment of interest for future research.

The term "cloning" refers to a laboratory procedure that creates millions or even billions of copies of a single molecule, most frequently DNA. In contrast to how the terms cellular cloning and organism cloning are used in reproductive genetics, this is not cloning.

We can investigate the molecules in the lab by amplifying or creating numerous copies of the DNA using molecular cloning.

Explanation:

Meiosis is a cell division process. A single cell undergoes two divisions, and produces four sex cells or gametes. Sex cells are the sperm in males and the eggs in females. These cells have half of the genetic information.

These cells are used in sexual reproduction. When they fuse, or fertilize, a zygote is formed. The zygote gets half of the genetic information from the mom (egg) and the other half from the dad (sperm). The zygote will develop into an embryo and then a fetus.
