Explanation:

Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.

Research this issue, and summarize what’s known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?

Answers

Answer: Yes.

Explanation: Because if it causes disease or problem then why continue to do it?

Answer: Well, from what my research is saying. cell phones emit low levels of non-ionizing radiation when in use. It can also referred to as radio frequency (RF) energy. And as stated by the National Cancer Institute, "there is currently no consistent evidence that non-ionizing radiation increases cancer risk in humans. So, it has not been proven weather or not you could get a tumor or cancer from the energy waves.

Some information about a radio wave is that we can have an energy of around 4 x 10-10 eV.

Okay so, I do think people should limit their cell phone use for other reasons. For one, Phones can be overly addicting, I do speak from experience. Phones can also take up way to much of your time is you're just scrolling around on them.

Explanation: So at least that's what I would say. Hope this helped! :)

4. Genetic Equilibrium...explain it.

Answers

Answer: Genetic equilibrium is a situation where allele frequencies in a gene pool are not changing. In other words, the population is not evolving. The conditions to maintain the genetic equilibrium are no mutation, no gene flow, large population size, random mating, and no natural selection. The equilibrium can be disrupted by deviations from any of its five main underlying conditions.

An example of this in humans would be a heterozygote for brown eye color. The person would carry both a dominant brown allele “A” and a recessive blue allele “a” yet have brown eyes. The dominant brown allele masks the recessive blue allele. Genetic equilibrium is the state in which allele frequencies remain constant.

The function of the menstrual cycle is to prepare the egg for fertilization true or false?

Answers

True
There are many parts to the menstrual cycle but the longest part of it is getting the egg to get fertilized. After beginning to fertilize there will be a a “window” where the egg will be the most fertilized. This phase is called the ovulation phase. If the egg isn’t fertilized, the body gets ready to dispose of the egg and now the egg is disposed through what is known has the period

Use the terms on the right to complete the sentence. Starting with a diploid parent cell containing 32 chromosomes, determine what mitosis and meiosis would yield.

(2 options, 1 point each) Meiosis would yield _____ cells with _____ chromosomes in each daughter cell. (2 options, 1 point each)

Answers

Answer:

Mitosis would yield _2 diploid_ cells with __32__ chromosomes in each daughter cell. Meiosis would yield _4 haploid_ cells with _16_ chromosomes in each daughter cell.

Explanation:

There are two principal types of cells in the organism: Somatic diploid cells (2n) that reproduce by the process of mitosis, and germ cells that are diploid reproductive cells in charge of gamete production. Germ cells divide by mitosis and meiosis. Through the process of mitosis, they originate more sexual cells, but through the process of meiosis,  they give place to haploid gametes, called sperm and egg cells, through the gametogenesis process.

Both somatic cells and germinal cells will end their cycle becoming two daughter cells with the same genetic dotation.

Gametes´destiny is to merge during fecundation, and a new diploid cell called zygote emerges through fertilization. The zygote is a complete cell and suffers successive mitosis to form the new organism.

Meiosis produces four daughter haploid cells (n) from a diploid germ cell (2n). Each daughter cell is haploid because they have half the number of the chromosomes of the original one.  

Mitosis produces two daughter diploid cells (2n) from a diploid somatic cell (2n). During mitosis, the whole-cell first duplicates and then separates.

Answers

Answer:

Explanation:

Ribosomes would be distributed throughout a prokaryotic cell, but would be found restricted to the nucleus of an eukaryotic cell.

What are ribosomes?

Eukaryotic cells have a distinct nucleus that separates the genetic material from the cytoplasm, which is where ribosomes are located in prokaryotic cells. The DNA in eukaryotic cells is packaged into chromosomes within the nucleus, while prokaryotic cells have a single circular chromosome located in the cytoplasm.

The cell membrane is present in both prokaryotic and eukaryotic cells, but chloroplasts are only present in eukaryotic cells that have the ability to perform photosynthesis, such as plant cells.

The animal body systems which may be involved in homeostasis are only the nervous system and endocrine system.

What do you mean by Homeostasis?

Homeostasis may be defined as a circumstance of balance among all the body systems required for the body to endure and function correctly.

The endocrine system consists of a series of glands that secrete chemical regulators known as hormones that play a critical role in maintaining the normal body conditions physically.

The ultimate control of homeostasis is performed by the nervous system which conducts the electric impulse and sends internal and external stimuli signals to the brain.

Therefore, the animal body systems which may be involved in homeostasis are only the nervous system and endocrine system.

Phosphorus is stored and cycled between living and non-living things.

What is non living things?

In biology, anything devoid of life, such as an inanimate item or body, is referred to as a non-living thing. A non-living creature lacks the traits that define a living thing as compared to the one that has life.

A non-living entity, for instance, lacks the essential component of life, a living cell that develops, metabolizes, reacts to environmental cues, reproduces, and adapts.

There are two representations of inanimate objects. On the one hand, a non-living thing refers to an object that once had life but has since passed away. A non-living thing, on the other hand, is one that never had life and never will have life.

Therefore, Phosphorus is stored and cycled between living and non-living things.
