Termite gut microbes provide the enzymes needed to degrade plant polymers, synthesize amino acids, recycle nitrogenous waste, and fix atmospheric nitrogen (N2) (Benemann, 1973; Breznak et al., 1973; Potrikus and Breznak, 1981; Bentley, 1984; Bignell, 2000; Brune and Ohkuma, 2010).

Explanation:

Hopefully this is the answer you are looking for.

Answer:

In transcription, the DNA sequence of a gene is "rewritten" in RNA. In eukaryotes, the RNA must go through additional processing steps to become a messenger RNA or mRNA. In translation, the sequence of nucleotides in the mRNA is "translated" into a sequence of amino acids in a polypeptide (protein chain).

Translation starts at a methionine (Met) codon, which specifies the amino acid methionine (Met). Translation stops at a Stop codon, which does not specify an amino acid.

Translation of an mRNA molecule by the ribosome occurs in three stages: a. initiation

b. elongation

c. termination.

During initiation, the small ribosomal subunit binds to the start of the mRNA sequence.

Translation happens in four stages: activation (make-ready), initiation (start), elongation (make longer), and termination (stop). These terms describe the growth of the amino acid chain (polypeptide).

The statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false. Sporulation is a process where some bacteria transform into a dormant state called a spore. Only one spore is produced per bacterial cell during sporulation.

Bacterial sporulation is a process where some bacteria convert to a dormant state called a spore. Sporulation can occur in some bacteria species under stress conditions such as a lack of nutrients. Sporulation starts when the bacterial cell divides into two unequal-sized compartments. One compartment is the smaller forespore while the other is the larger mother cell.

The mother cell engulfs the forespore within itself and forms a spore. Only one spore is produced per bacterial cell during sporulation. These spores can survive in harsh environments and then germinate into new bacterial cells when conditions are favorable again. Therefore, the statement "For every bacterial cell that undergoes sporulation, there are two resulting bacterial cells" is false.

Answer:

Which of the following explains the most likely effect this toxin will have on the Calvin cycle? Carbon dioxide will not be converted into carbohydrates. The toxin inhibits RuBisCO from catalyzing the joining of carbon dioxide with RuBP. This prevents carbon fixation, so the Calvin cycle will not occur.

A. After the statement quiz2 xVar, yVar executes in main, xVar contains 9 (decimal).

B. The statement quiz2 2, 6 will produce an error when the macro is invoked. (False)

C. Upon completion, EDX will contain 90 (decimal).

A. The quiz2 macro multiplies the value of pVar with itself using the MUL instruction and performs the multiplication for the number of times specified by qvar using the LOOP instruction. In this case, xVar is initially set to 3, so when it is passed as the pVar argument to quiz2 along with yVar (also 3) as the qvar argument, the macro will execute the multiplication loop 3 times. Therefore, xVar will be multiplied by itself three times, resulting in 9.

B. The quiz2 macro accepts two arguments, pVar and qvar, and does not impose any restrictions on the values that can be passed to these arguments. As long as the arguments are valid DWORD values, the macro will execute without producing an error. Therefore, the statement quiz2 2, 6 will not produce an error when the macro is invoked.

C. In the given code snippet, the value 10 is assigned to EBX, and the value 3 is assigned to EDX. Then the quiz2 macro is invoked with EBX as pVar and EDX as qvar. The macro multiplies EBX (10) with itself three times, resulting in 1000. Since EDX is not modified within the macro, it retains its initial value of 3. Therefore, upon completion, EDX will contain 3 (decimal).

The correct order of organization in animals is Cell, tissue, organ, organ system, organism—that is what is written in the option D. The cell is the first to form, followed by tissue, and finally organs and organ systems.

At the early stage, unicellular individuals were seen, and later, due to development, multicellular individuals were developed. The unicellular organism has only cells, then those cells unite to make a tissue, and in a tissue all the cells have the same function. An example is epithelial tissue, which is made up of many epithelial cells.

Tissues combine to form an organ, and organs combine to form an organ system. An example is an organ such as the liver that is made up of many tissues, but all tissues perform certain functions that are required for the liver, and in the same way, the organ system and the organism are developed.

Some cnidarians go through both a motile and a sessile (attached) stage during their life cycle. The migratory free-floating stage is called a medusa.

Cnidarians are a phylum of aquatic animals that are mostly marine. The distinguishing feature of this phylum is the presence of stinging cells known as nematocysts, which they use for catching prey and self-defense.

Corals, jellyfish, sea anemones, and hydra are all examples of cnidarians. Cnidarians have a life cycle that includes both a motile and a sessile stage.

They start as a larva that swims freely and settles on the ocean floor, where they become sessile polyps. Medusa is a migratory, free-floating stage in cnidarians' life cycle in which they are able to reproduce by releasing sperm and eggs.

Cnidarians have asexual and sexual reproduction. Polyps reproduce asexually by budding, and medusae reproduce sexually.

Cnidarians have both male and female reproductive organs, although some species can only produce one gender.

Fertilization happens internally, and the zygote develops into a ciliated planula larva that swims freely and eventually settles on the sea bottom, where it transforms into a sessile polyp.

Explanation:

photosynthesis is the process in which plant make their own food with the help of sunlight,water and carbon dioxide. water and carbon dioxide are raw materials in photosynthesis because they help to prepare their food.During photosynthesis, plants take in carbon dioxide and water from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.so sunlight water and carbon dioxide should go in which create oxygen.
