Answer:

It depends on the structure of labeled A.

Explanation:

If the diagram shows the structure of flower, so we can say that it has the ability to attract insects and other animals. If the diagram shows the structure of an insect such as bees so we can say that it can moves the pollen to the ovaries. If the diagram indicates the structure of pistil which is a female part of the flower so we choose that it catches the pollen and if the diagram represents the structure of anther which is a female part so we choose that it produces pollen.

Now that you have identified the components of DNA, can you describe how these components bind together to form a DNA molecule?
omeli [17]

The question is incomplete. The complete question is attached below.

Answer:

1. DNA is the polymer of deoxyribonucleotides that contain the nitrogenous base, pentose sugar and phosphate group. The phosphate is attached with the 3 C position of the deoxyribose sugar. This leads to teh formation of phosphodiester bond.

2. The DNA backbone consists of phosphate and sugar. The nitrogenous bases are inserted inside the DNA molecule. These nitrogenous bases are linked together by the hydrogen bonds.

3. The adenine binds requires two hydrogen bonds to bind with thymine. This provide complementary nature to the DNA molecule. Uracil is present instead of thymine in RNA .

4. The guanine binds requires three hydrogen bonds to bind with cytosine. More amount of energy is required to break their bonds.

Explanation:

A type of society in which food production—carried out through the use of human and ... Production is slow, and the amount that can be produced is limited. In preindustrial societies most economic activities are carried out within the home setting. ... Higher crop yields allow agricultural societies to support large populations.

Explain how the terms oxidation and reduction apply even when there is only a partial shift of electrons between atoms linked by
aliina [53]

Explanation:

In a covalent bond, there is sharing of the donated electron by two atomic species having very small electronegative differences between them.

Oxidation is the loss of electrons by a specie and it usually lead to an increase in oxidation number.

Reduction is the gain of electrons by a specie. It leads to a lower oxidation number.

Since there is no actual loss of gain of electrons in a covalent body, the electronegativiy is at work.

Electronegativity is the ability of a specie to draw the shared electrons more to itself in a covalent bond.

  • Between two atoms bonded covalently, the more electronegative specie draws the electrons closer.
  • This leaves a partial negative charge on it.
  • The other electron then becomes partially positively charged.
  • We can then say, the more electronegative specie undergoes reduction.
  • The less electronegative one undergoes oxidation.
