_____ converts atmospheric nitrogen into ammonium, which plants absorb. The plants, by _____, incorporate the ammonium into proteins. Ammonification, nitrification;Nitrogen fixation, assimilation;Assimilation, nitrogen fixation; or Nitrification, denitrification?which one?

Answers

Answer 1
Answer: The answer is Nitrogen fixation, assimilation.

Plants are not able to directly use atmospheric nitrogen. It must be converted into different form through a nitrogen cycle. In the process of nitrogen fixation, nitrogen fixing bacteria converts atmospheric nitrogen into ammonium. In the process of assimilation, plants incorporate ammonium into proteins.
The next steps are ammonification, conversion of organic nitrogen from dead plants back to ammonium; nitrification, conversion of ammonium to nitrates; and denitrification, conversion of nitrates into atmospheric nitrogen.

The cell cycle consists of 5 distinct phases: I, M, G1, S, and G2. All preparation for cell division occurs during M phase. At any stage of mitosis, a cell has twice as much DNA as in G1. Metabolically active cells can exit, and sometimes re-enter, the cell cycle. Extracellular conditions have no effect on cell cycle progression. Once the cell cycle has begun, it cannot be stopped without resulting in cell death.

The inability to start a pregnancy after having unprotected vaginal intercourse for more than a year or the inability to stay pregnant for the full length of a normal pregnancy is?

When exposed to bright sunlight, some people involuntarily sneeze. This reaction is known as a photic response. It is controlled by a single gene with two alleles, H and h. A man and a woman who sneeze when exposed to bright sunlight are both heterozygous for the photic response trait. Draw a Punnett Square using the allele symbols H and h to show the expected genotypes of the man and woman’s biological children. Identify all possible phenotypes of the offspring and their expected percentages.

Answers

The correct answer is explained below:

Explanation:

  • According to the question,
  • The dominant allele for the photic response gene is: H
  • The recessive allele for the photic response gene is: h.
  • It is said that both the man and the woman are heterozygous for the photic response trait, that is, both of them have the Hh genotype.
  • Both sneeze when exposed to bright sunlight, hence both of them show the photic response phenotype.
  • This means the photic response trait is a dominant trait.
  • Gametes produced by both the man and woman are: H and h.
  • Mating the man with the woman, we get offspring with the following genotypes and phenotypes.

                                               H                     h

                              H             HH                  Hh

     Photic Response         Positive          Positive

                               h             Hh                   hh

     Photic Response         Positive          Negative

  • From the above Punnett square we get,
  • Percentage of offspring expected to show photic response trait = (3)/(4) = 75 %.
  • Percentage of offspring expected to not show any photic response trait = (1)/(4) = 25 %.

Which organelle is used for carrying out photosynthesis?

Answers

The organelle that carry out photosynthesis is the chloroplast.

Explanation:

Chloroplasts are organelles, functional subdivisions, in plant and algal cells. The central role of chloroplasts is to carry photosynthesis.Chloroplasts are organelles observed in plant cells and eukaryotic algae that accompany photosynthesis. Chloroplasts receive sunlight and use it in combination with water and carbon dioxide gas to generate food for the plant. . In this regard, they are similar to mitochondria but are observed only in plants and protista.

Chloroplast is used for carrying out photosynthesis. Photosynthesis is a process by which plants gets it's food.

What is chloroplast?

Plants and algae have chloroplasts, which're essential, for capturing energy and transforming carbon dioxide and water into oxygen and glucose.

Chloroplasts have a structure with two membranes. They also house a specialized membrane system called the thylakoid membrane.

The thylakoid membrane serves as the site for the reactions, in photosynthesis. During these reactions water molecules are split using energy to obtain hydrogen and oxygen. The hydrogen is then utilized to create ATP, which acts as the cells energy currency.

Which component of a virus is lacking in a cell?

Answers

Capsid is the component of a virus that is lacking in its cell

A capsid is the protein shell that surrounds a virus. Capsids functions by protecting the nucleic acids of a virus while interacting with the host environment. Capsids are made up of many oligomeric structural subunits that contains the protein; protomers. Capsids are generally grouped based on their structure. The common ones are helical and icosahedral.
