The right answer is B.
Nitrogen fixation is done by decomposers that are prokaryotes (bacteria).
<u>Take the example of legumes.
</u>
The different species of rhizobia bacteria, which are able to infect the roots of legumes (Fabaceae family), are specific to certain host plants. Rhizobium phaseoli infects beans (Phaseolus sp).
Bacteria cause the formation of nodules on the roots by penetrating the root hairs, and transform into larger "bacteroids". The nodules are the seat of a symbiotic activity in which the plant provides the sugars and energy from photosynthesis, and in return benefits from the amino acids that are produced there.
<h2>Correct answer is option "A"</h2>
Explanation:
- The initial concentration of the substrate(Keeping the initial substrate concentration steady permits the specialist to think about the response rates under various natural conditions. The response rates will furnish the scientist with data about the protein's capacity in various situations).
- A substrate is a substance that is used to make a final product. It is changed and reformed during the process. Sometimes chemical groups are added or taken away.
- In the cell, enzymes bind and change substrates into their final product. When the enzyme is bound to the substrate, it is known as an enzyme-substrate complex.
- Substrate concentration is the amount of substrate present that can be turned into a product. The unit of measurement usually assigned to eggs is dozen. Substrate concentration can be measured in various ways. Since the substrates inside the cell are suspended in cellular fluid, the substrate concentration is most commonly measured in molar concentration, or molarity (M), which is moles per liter.
- Hence,the correct answer is option A "the initial concentration of the substrate.
Answer:
yes but they wont be fertile
The Van der Waal’s forces are the forces, which are formed by the attraction of two opposite charged bodies. This charge exists due to the formation of the dipoles in the molecules or atom. The dipoles formed due to the movement of the electron in the atoms. The strength of the dipole or Van der Waal attraction depends on the size of the atoms or the molecule. As the size increases, the strength of the Van der Waal force increases. The positive and the negative regions are shown in the attached picture.
<span>The event that a "the first male has had a kidney stone" and b "the second male has had a kidney stone" is true. Random selection is used by the medical researcher in selecting two males from the population. Since simple random sample is defined as a subset of a statistical population wherein each member has an equal probability of being chosen, even if the probability is only 8%, males a and b may really have had a kidney stone. </span>
