When a single-celled organism reproduces,what is the result​

Answers

Answer:

its called asexual reproduction

When a single-celled organism reproduces, asexual reproduction takes place.

What do you mean by asexual reproduction?

Asexual reproduction is a type of reproduction that does not involve the fusion of gametes or change in the number of chromosomes.

Asexual reproduction is a mode of reproduction in which a new offspring is produced by a single parent. The new individuals produced are genetically and physically identical to each other, i.e., they are the clones of their parents.

In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism.

Which of the following organic molecules are most closely related to proteins? sugars amino acids fatty acids nucleotides​

Answers

Answer:

Amino acids

Explanation:

Proteins are made up of amino acids which come together to form polypeptide chains.

The organic molecule that is closely related to proteins are amino acids. The correct option is B.

What are amino acids?

Amino acids are molecules that form proteins when they combine. The fundamental components of life are amino acids and proteins.

Amino acids are left over after proteins are digested or broken down. To help the body, the human body uses amino acids to make proteins: Food should be broken down.

Isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine, cysteine, tyrosine, histidine, and arginine are the 12 amino acids.

An amino acid is an organic molecule composed of a basic amino group, an acidic carboxyl group, and a unique organic R group (or side chain) for each amino acid. Alpha-amino carboxylic acid is the chemical formula for amino acids.

Thus, the correct option is B.

B. the same because chromosomes are copied prior lo melosis

C. different due to DNA replication prior to mitosis

D. different due to independent assortment during meiosis​

Answers

Answer:

D). different due to independent assortment during meiosis​

Explanation:

Gametes that an organism produces accommodates a blend of genes of that organism and in each gamete, this blend or combination is 'distinct and that is due to independent assortment during meiosis.' It implies that the chromosomes pass randomly for isolation of poles during the division of cells at the time of the process of meiosis and this independent segregation causes each gamete to contain a unique combination of genetic code. Thus, option D is the correct answer.

One side of the water molecule has a positive charge, while the other side has a negative charge. What do the charges indicate about the molecule?

Answers

Answer:

That its a nuetral

Explanation:

In the given case of water molecule, the charges shows that it is a polar molecule.

What is a polar molecule?

It is a molecule in which one terminal of the molecule is slightly positive and the other terminal is slightly negative. In the case of water molecule, the unequal sharing of electrons provides the molecule with a slight negative charge close to its oxygen atom and a slight positive charge close to its hydrogen atoms.

When a neutral molecule, possesses a positive region at one terminal and a negative region at the other, it is considered as a polar molecule. The molecules of water attract each other on the basis of the positive end of one water molecule and the negative end of the other molecule of water.

Thus, the charges shows that it is a polar molecule.

This flower must have grown in neutral soil, with little aluminum.

In some varieties of bigleaf hydrangeas (Hydrangea macrophylla), soil pH determines whether the plant will produce blue or pink flowers. Blooms appear bluest when grown in acidic soil with a pH in the 5.0 to 5.5 range. The same cultivar may sport pink blossoms in soil with a more neutral pH, such as 6.5 to 7.0.

b) selectively controls what enters and exits the cell.

c) is composed of two protein layers with lipids floating inside.

d) is composed of protein and carbohydrates only.

Answers

Answer:

Explanation:What’s a cell? Well, on some level, it's a bag of goo. The plasma membrane—the outer boundary of the cell—is the bag, and the cytoplasm is the goo.

Of course, a cell is ever so much more than just a bag of goo. It's a complex, highly organized unit, the basic building block of all living things. And the plasma membrane and cytoplasm are actually pretty sophisticated.

The membrane is a delicate, two-layered structure of lipids and proteins, and it controls what can enter and exit the cell. Similarly, the cytoplasm of a eukaryotic cell consists not only of cytosol—a gel-like substance made up of water, ions, and macromolecules—but also of organelles and the structural proteins that make up the cytoskeleton, or "skeleton of the cell."

In this article, we’ll take a closer look at the plasma membrane and cytoplasm.

The plasma membrane

Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.

A phospholipid is made up of a hydrophilic, water-loving, phosphate head, along with two hydrophobic, water-fearing, fatty acid tails. Phospholipids spontaneously arrange themselves in a double-layered structure with their hydrophobic tails pointing inward and their hydrophilic heads facing outward. This energetically favorable two-layer structure, called a phospholipid bilayer, is found in many biological membranes. [Close-up of a phospholipid]

As shown below, proteins are also an important component of the plasma membrane. Some of them pass all the way through the membrane, serving as channels or signal receptors, while others are just attached at the edge. Different types of lipids, such as cholesterol, may also be found in the cell membrane and affect its fluidity.

List the six nitrogen bases that would pair with the following sequence of bases in a strand of DNA : T C G A C A

Answers

Answer: thymine (T) Cyostine (C) guanine (G) adenine (A)

Explanation:

Guanine (G) is complementary to cytosine (C), and adenine (A) is complementary to thymine (T). Hence, the nitrogenous bases that would form for the DNA bases TCGACA are AGCTGT.

     

How does base pairing take place in DNA?

A DNA double helix is joined together by the hydrogen bonds that are formed between the nitrogenous bases in the opposite strands. Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) are the nitrogenous bases present in the DNA. Both adenine and guanine are purines. They make bonds with pyrimidine.

Adenine (A) of one DNA strand makes a double bond with Thymine (T) of the opposite DNA strand. The guanine (G) of one DNA strand makes three hydrogen bonds with the cytosine (C ) of the opposite DNA strand. As there are three hydrogen bonds present in guanine and cytosine (GC), they require more energy to break the bond. Adenine and thymine (AT) have two hydrogen bonds, hence they require less energy than GC bonds.

Hence, in a DNA strand, the complementary strand of TCGACA is AGCTGT.
