Polyamino is not a name for a chain of amino acids.
what are amino acids?
An amino acid is a fundamental molecule that serves as the building block for proteins. There are 20 different amino acids. A protein consists of one or more chains of amino acids (called polypeptides) whose sequence is encoded in a gene. Some amino acids can be synthesized in the body, but others (essential amino acids) cannot and must be obtained from a person’s diet.
therefore option B is the correct answer.

What is tissue? Include examples for both plants and animals.
Answer:Plants are simpler organisms than animals, having three organ systems and fewer organs than do vertebrate animals. Organs are composed of tissues, which are in turn composed of cells. Plants have three tissue types: ground, dermal, and vascular. Animals have four: epithelial, connective, muscle, and bone.

Moles are small mammals that are virtually blind and live in underground burrows for most of their lives. This is an example of the interaction between which Earth's systems?
A. biosphere/lithosphere
B. Lithosphere/hydrosphere
C. hydrosphere/biosphere/lithosphere
D. Atmosphere/lithosphere/hydrosphere
Answer:
A. biosphere/lithosphere
Explanation:
The habitat of moles in underground burrows shows the interaction between the biosphere and lithosphere.
The biosphere the region of the earth occupied by living organisms.
The lithosphere is the solid part of the earth
Organisms interacts with the lithosphere in diverse ways. For underground burrowers, their dwelling place is situated in crevices and holes. This interdependence highlights the interaction between the spheres in nature.Which statement is true of recessive sex-linked traits such as color blindness ?

arrange the events of meiosis l of an animal cell in the correct order
Answer:
DNA condenses into chromosomes (prophase)
Homologous pairs align to initiate crossover (metaphase)
Microtubules pull apart the homologous pairs toward opposite poles (anaphase)
Nuclear envelopes develop around the nuclei (telophase)
Why is it important that the DNA is replicated during the S phase of interphase
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.
what is cell diversity and why is it important?
this phenomenon, which provides evidence for the big bang theory, is called what?
Answer:
Doppler Red-Shift Evidence
Explanation:
The Doppler red-shift of light observed from distant stars and galaxies gives evidence that the universe is expanding (moving away from a central point). This allows for Big Bang Theory, because after a “bang” occurs all of the matter moves away from the point of origin.

There are a number of key enzymes that function in the replication of DNA. Using your book and other resources, identify what these key enzymes do.
DNA Polymerase (identify two jobs):
Helicase:
Primase:
Ligase:

How does homeostasis maintain a balance in an ecosystem?
Answer: It is known as ecological homeostasis to the exchange that takes place between diverse natural means that allow to maintain a balance within an ecosystem. These adjustments are considered necessary to achieve survival. Usually these homeostatic balances can be understood by observing populations or systems that depend on each other.

Phytopharmaceuticals are pharmaceutical compounds that are found in plants. They can be naturally occurring or a result of biotechnology. Recently, scientists created genetically modified (GM) corn that produces the antibiotic penicillin. The seeds of this GM corn contain a large amount of the antibiotic penicillin, making the cost of producing the penicillin much cheaper and making the method of delivering it to patients in need much easier. Given the benefits of this GM corn, which of the following may be a concern regarding its production?
A.The GM corn may develop infections from bacteria that are sensitive to the antibiotic.
B.The GM corn might pass resistant genes to other organisms, like birds, that may eat the seeds.
C.Because corn uses the wind for pollination, people allergic to penicillin may be at risk for exposure to the antibiotic in the air.
D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Answer:
The answer is D.Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
Explanation:
The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
What are genetically modified crops?Through the use of laboratory procedures, genetic modification (GM) technology enables the transfer of genes for particular traits between species.
In the middle of the 1990s, GM crops were first made available in the U.S. The majority of GM crops being farmed in the U.S. have been modified to be herbicide or insect resistant. The three GM crops with the highest acreages are corn, soybeans, and cotton.
The technology has the potential to be used in the future to improve nutrition, stress tolerance, disease resistance, biofuel efficiency, and the cleanup of polluted places.
The U.S. Department of Agriculture (USDA), the Environmental Protection Agency (EPA), and the Food and Drug Administration (FDA), each with the ability to regulate particular parts of the crops, are in charge of regulating GM crops at the federal level.
Therefore, The correct option is Increased availability of the antibiotic may increase the development of antibiotic resistance in the infectious agents penicillin is used to treat.
