Answer:

3.) nucleic acid

Explanation:

Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).

Biological macromolecules are organized into four main categories and these includes;

I. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.

II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.

III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.

IV. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.

Hence, the type of macromolecule that contains phosphorus as part of a phosphate group (sugar 2-deoxyribose) is nucleic acid.

From the biological macromolecules, Nucleic acids contains phosphorus as part of a phosphate group.

Nucleic acids are biopolymers, macromolecules, crucial for all known types of life. Nucleotides, which are the monomer components, make up their structure. a sugar with five carbons, a phosphate group, and a base with nitrogen. Deoxyribonucleic acid and ribonucleic acid are the two main types of nucleic acids.

Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two types of nucleic acids that carry genetic information that is read by cells to create the RNA and proteins that allow living things to function.

Electric eels are part of a group of animals called electric fish.These cells pump positively charged sodium atoms, called ions, from inside themselves to the outside.

Explanation:

Brainliest? plz

Electric fish is a part of the group of animals which are responsible for producing charge. These organisms pump positively charged sodium ions from inside themselves to the outside environment.

An electric fish is an fish that can generate electric fields and transfer current through themselves. Most of the electric fishes are electroreceptive, which means that these fishes can sense the electric fields present in the environment. The only exception here is the stargazer family which is not electroreceptive.

The examples of electric fish includes Electric eel, that belongs to the genus Electrophorus, South American knifefishes responsible for the production of powerful electric shocks to stun prey.

If the electric fishes are supplied with the negative charge always then they will pump positive charge to neutralize the effect of that charge.

Explanation:

Contact inhibition is a process of arresting cell growth when cells come in contact with each other. As a result, normal cells stop proliferating when they form a monolayer in a culture dish. Contact inhibition is a powerful anticancer mechanism that is lost in cancer cells

Contact inhibition is the property of normal healthy cells where the cells cease growth after coming in contact with each other. A lack of this property results into uncontrolled growth of cells.

Contact inhibition is the property of normal healthy cells which enables the cells to cease proliferation and growth when they come in contact with each other. This property is lost by the cell when the cells undergo malignant transformation. As a result, this leads to uncontrolled proliferation and solid tumor formation in the body.

In the in-vivo culture of cells, contact inhibition arrests cell growth and as a result, normal cells stop proliferating when they form a monolayer in the culture dish. Contact inhibition is a powerful anticancer mechanism which is lost in cancer cells.

Answer:

Please find the explanation as to why Ravyn is albino when neither of her parents is abino below

Explanation:

According to Gregor Mendel in his law of dominance, a DOMINANT allele is a form of a gene (allele) that masks the phenotypic expression of another in a gene while the RECESSIVE allele is the allele being masked. This means that an allele can be present in a gene but in a masked or recessive condition.

According to this question, Ravyn happened to be an albino when neither of her parents is albino because BOTH of his PARENTS are HETEROZYGOUS for the skin color trait i.e. they both contain the allele for normal skin color, which is dominant, and the allele for albinism, which is recessive. Note that a recessive trait will only express itself when in a pure breed condition, hence, both parents contributed the reccesive allele (albinism) to produce the recessive condition in Ravyn.

In a nutshell, Ravyn is an albino because his parents are heterozygous and both passed on the recessive alleles to him.

Answer:

Nonsense mutations occur when a premature nonsense or stop codon is introduced in the DNA sequence. When the mutated sequence is translated into a protein, the resulting protein is incomplete and shorter than normal. Consequently, most nonsense mutations result in nonfunctional proteins.

The species of bacteria that colonize our respiratory and digestive systems help set up checks and balances in the immune system. White blood cells police the body, looking for infections, but they also limit the amount of bacteria that grow there. Likewise, bacteria keep white blood cells from using too much force. Bacteria also help out by doing things cells are ill-equipped to do. For instance, bacteria break down carbohydrates (sugars) and toxins, and they help us absorb the fatty acids which cells need to grow. Bacteria help protect the cells in your intestines from invading pathogens and also promote repair of damaged tissue. Most importantly, by having good bacteria in your body, bad bacteria don’t get a chance to grow and cause disease.

Some species of bacteria in your body can result in diseases, such as cancer, diabetes, cardiovascular disease, and obesity. Usually, these diseases happen only when the normal microbiome is disrupted, but that can occur even from antibiotics. Antibiotics kill bacteria, and some of those will be good bacteria that we need to protect our health. When that happens, the bad bacteria that normally are kept in check have room to grow, creating an environment ripe for disease.

Bad bacteria can exist at low levels in your body without causing harm or can grow too much and wreak havoc. Staphylococcus aureus can cause something as simple as a pimple or as serious as pneumonia or toxic shock syndrome. P. gingivalis can cause gum disease, and was recently linked to pancreatic cancer (read our article find out more). Similarly, when not suppressed by good bacteria, Klebsiella pneumonia can cause colitis, and subsequently lead to colorectal cancer.

In addition to allowing disease-causing bacteria to flourish, the elimination of good bacteria throws  the immune system out of whack. The result can be simple allergies or very debilitating autoimmune diseases. Without the right balance of bacteria, your body might suffer from constant inflammation.

Inflammation is the body’s alarm system, which calls white blood cells to heal a wound or to get rid of infection. Chronic inflammation, however, can make the body more susceptible to autoimmune diseases and cancer, such as causing inflammatory bowel disease which if uncontrolled can cause colon cancer.

Its either B or C, look closely at the question and at the answers, you can narrow it down from then.

A scientist is treating rice plants with a chemical that causes mutations. The possible benefit of this treatment is transgenic plants. Hence, the correct option is B.

A mutation is a change in the DNA sequence that makes up a gene. It can result from  errors in DNA replication or exposure to mutagenic agents such as chemicals or radiation, or from spontaneous changes.

Transgenic plants are the plants that have been genetically modified to express specific traits or traits that are not found in the original species. This is done by introducing foreign DNA or chemicals that change the plant's genome. This process is called genetic engineering.

Transgenic plants have become an important tool in agriculture and biotechnology, providing new opportunities for food production, environmental protection and economic growth. Hence, the correct option is B.
