Answer:
A) birds have a large opening where the beak should be.
Explanation:
when scientists turn off the gene that makes beaks in birds, the birds have a mouth where no teeth are present. The birds have mouth because the bird resembles and closely related to the dinosaur. There are some proteins that is responsible for the occurrence of beak but when the genes are turn off these protein stop producing that leads to turn the beak place into mouth.

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?
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.

Which animal body systems may be involved in homeostasis?
A. only the circulatory system
O
B. only the circulatory system and respiratory system
C. only the nervous system and endocrine system
D. all body systems
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.

Answer:

Explanation:

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.

Answer:
a
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.

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. NOTE: Some terms may be used twice, or not at all. Incorrect answers will cancel out correct answers. 16 chromosomes 2 haploid cells 2 diploid cells 8 chromosomes 4 haploid cells 32 chromosomes 4 diploid cells Mitosis would yield _____ cells with _____ chromosomes in each daughter cell. (2 options, 1 point each) Meiosis would yield _____ cells with _____ chromosomes in each daughter cell. (2 options, 1 point each)
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.

Answer:
pollinators + the wind
Explanation:
pollinators is probably the best answer here... pollinators are bugs like bees and butterflies that spread the pollen from one plant to another.

Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.
