Rhizobium bacteria are important for plants because plants cannot use nitrogen from the air.

<u>Explanation</u>:

  • Rhizobium bacteria are micro organisms that fix nitrogen available in the atmosphere.
  • For nitrogen fixing, they need to associate with plants. They cannot do it independently.
  • So they make use of a plant host like legumes. In the roots of such plants, they fix nitrogen in the air to ammonia and other organic compounds. This is very useful for improving the soil fertility.
  • In return, the plants give compounds prepared by photosynthesis for its survival. So the relationship is mutually beneficial.

which statement correctly compares and contrast the three stages of cellluar respiration that occurs in the presence of oxygen
Lapatulllka [165]
<h2><u>Full Question:</u></h2>

Which statement correctly compares and contrasts the three stages of cellular respiration that occur in the presence of oxygen? Each stage occurs in the mitochondria, but only the final stage produces ATP. Each stage produces ATP, but only the third stage occurs in the mitochondria. Each stage produces ATP, but only the first stage occurs in the cytoplasm. Each stage occurs in the cytoplasm, but only the final stage produces ATP.

<h2><u>Answer</u>:</h2>

Each stage produces ATP, but only the first stage occurs in the cytoplasm.

<h3><u>Explanation</u>:</h3>

Cellular respiration is the process by which the glucose or any respiratory substrate is burned down inside a cell producing ATP or energy. This process of cellular respiration is seen in each and every living cell. The glucose is burned in the cytoplasm of the cell producing the pyruvate. This pyruvate is decarboxylated into Acetyl CoA and transferred inside the mitochondria. So the glycolysis or the 1st step of cellular respiration occurs in cytoplasm and rest inside the mitochondria.

ATP is produced from each astep of cellular respiration. So the correct option is option C.

Regarding the planes of axes, a joint that is capable of moving through all three anatomical planes is called
storchak [24]

Answer:

Multiaxial joint

Explanation:

Joint is understood as the set of structures that allow the union of two or more bones and / or cartilage with each other. The synovial joint is a union that is established between bones that have different articular surfaces. There are factors that determine the axes of space in which a joint can be mobilized, in such a way that uniaxial, biaxial or multiaxial joints are identified. The multiaxial joint is movements in around three axes or three degrees of freedom. These joints can perform any movement. This movement that is carried out in the three axes is called circumduction movement (in a circle). The movements that a synovial joint can carry out are sliding, extension, flexion, abduction, adduction, medial rotation, lateral rotation, circumduction, protrusion, retrusion, diduction, pronation, supination, inversion, eversion, among others.

Leni [432]

Answer:

Aerobic respiration is the process of producing cellular energy involving oxygen. Cells break down food in the mitochondria in a long, multistep process that produces roughly 36 ATP. The first step in is glycolysis, the second is the citric acid cycle and the third is the electron transport system.

The consistent reduction in fitness (survival, reproduction, etc) in a population due to widespread non-random mating is called
igomit [66]

Answer:

Natural selection

Explanation:

Natural selection occurs when one allele (or combination of alleles of different genes) makes an organism more or less fit, that it is able to survive and reproduce in a given environment. If an allele reduces fitness, its frequency will tend to drop from one generation to the next.
