Answer:

Hello! DNA (Deoxyribonucleic Acid) is a molecule composed of two polynucleotide chains, which coil around each other to form a double helix that carries genetic instructions for the development, functioning, reproduction and growth of all known organisms and many viruses. DNA and the instructions contained in it passes from adult organisms to their offspring during the process of reproduction. Hope this helps ! :)

galina1969 [7]

Answer:

The student is wrong, spermatozoa are germinal cells and therefore mitochondrial mutations (likewise genomic nuclear mutations) are inherited by offspring

Explanation:

Although the probabilities of inheriting a mutation from a single sperm cell are low, it since an organism produces millions of sperm cells throughout its life span, the mutations in the germinal cells (i.e., sperms and ovules) are inherited by offspring

Equal masses of granite, iron, copper, and lead are placed in sunlight. Based on specific heat, which material will warm up the

levacccp [35]

Answer:

Lead

Explanation:

The material that will warm up the fastest would be lead.

The specific heat capacity of a substance is the amount of heat required to raise the temperature of a unit of the substance by one degree. The higher the specific heat capacity of a substance, the higher the amount of heat required to raise the temperature of the substance and vice versa.

The specific heat capacity (in J/g °C) of granite, iron, copper, and lead are as follows:

Granite - 0.790

Iron - 0.450

Copper - 0.385

Lead - 0.129

From the table, lead has the lowest specific heat capacity, hence, it will be the fastest to get warmed when equal masses of all the substances are placed in the sunlight.

The structure of a substrate P strongly resembles substrate Q. In an experiment, By mistake P was used instead of Q as a substra

Dvinal [7]

<h3>Answer;</h3>

C) P and Q have similar binding properties

<h3>Explanation;</h3>

Enzymes are biological catalysts that speeds up chemical reactions. Substrates are substances that are acted on by an enzyme to form a product.
An enzyme catalyzed reaction occurs when the substrate binds to the active site of an enzyme to form and enzyme-substrate complex.
Substrate P and Q are structurally similar which means they are in a position of binding and fitting in the active site of an enzyme. The strong structural similarity means that the binding properties of these two different substrates may be similar.
Formation of similar products or results when acted upon by an enzyme mean they are similar in terms of their binding properties, and thus the production of similar product.
