Answer:

a. All of the answers are correct.

Explanation:

During conjugation a bacteria transfers it's genetic material to another bacteria. The genetic material has genes in a particular order so we can easily know the order of the genes through experimentation. The transfer of genes occurs as per the time allowed. If two genes are nearby then they will be transferred one after the other.

For example in the given question, gene A was transferred to recipient bacteria in 26 minutes, gene M was transferred in 37 minutes while gene T was transferred in 45 minutes, it simply means that the order of genes is A M T. Gene M was transferred to another bacteria after A was transferred because time required to transfer it is 37 minutes which is less than time required to transfer A which is 26 minutes. Gene T took maximum time to get transferred so it will be last to be transferred.

After calculation, we can easily infer that the genetic distance between A and M is 11 minutes (37 minutes - 26 minutes = 11 minutes). Similarly we can get genetic distance between A and T as 19 minutes and between M and T as 8 minutes. So all the given options are correct.

Masteriza [31]

Answer:

Water is the common solvent of the body

Water is a polar, covalent molecule

The high heat capacity of water relates to its ability to absorb significant

amounts of heat before changing one degree celsius .

Acids have a higher concentration of free H+ than are found in bases

Explanation:

Water is also called universal solvent because it can dissolve a large number of polar compounds due to its polar nature. In water, covalent bond is present between hydrogen and oxygen due to which partial positive charge occurs on hydrogen and partial negative charge appears on oxygen atom due to difference in electronegativity values. Acids has high concentration of proton (H+) while bases has high amount of OH- ions.

Which best summarizes the findings of Griffith?
Irina-Kira [14]

Cells contain a transforming factor summarizes the findings of Griffith.

<u>Explanation:</u>

Numerous experts assigned to the description of DNA as the genetic material. During the 1920s, Frederick Griffith obtained an outstanding invention. He was inquiring two separate forces of a bacterium, called R (rough) strain and S (smooth) strain. He infused the two strains into mice.

Griffith settled that the R-strain bacteria must have brought up a "transforming principle" from the heat-killed S bacteria, which enabled them to "transform" into smooth-coated bacteria and become injurious. He called this method transformation, as something was "transforming" the bacteria of one strain into another strain.

Consider a general Eudicot flowering plant. Identify three major "above ground" structures and two major "below ground" structur
Novay_Z [31]

Answer:

See the answer below

Explanation:

<u>A Eudicot flowering plant is a plant that comes up with two seed leaves during the process of germination. Generally, Eudicot plants are characterized by netted venation of leaves, floral parts in 4/5 or multiples, and ring arrangement of vascular bundles.</u>

Three major above-ground structure of a typical Eudicot include;

1. <em>The stem</em>

2. <em>The leaves</em>

3. <em>The flowers</em> (for those that have reached maturity)

Two major below-ground structures of a typical Eudicot include;

1. <em>The roots</em>

2.<em> The root hairs</em>
