Answer:in the third stage

Explanation: Aerobic respiration requires oxygen to breath in the third stage. In the third stage glucose molecule is the source of energy. Aerobic respiration occurs were cell use oxygen to convert glucose into energy. When you breath in,you breath in oxygen,when you breath out,you breath out carbon dioxide.

During cellular respiration,our body needs the oxygen we breath in,to get energy from the food we eat. cell uses oxygen to break down sugar.

Answer:

  • The cellular respiration occurs in two main forms or mechanisms, the first one is the aerobic respiration which obviously takes place in the presence of the oxygen,O₂ molecule. While, the second takes place in the absence of the oxygen,O₂ molecules.
  • For, the aerobic form of cellular respiration the oxygen is required to be present during the  process of  releasing the optimum amount of energy or executing of the whole process in a more proper way.
  • <u>As, the aerobic respiration is executed in the following three steps:</u>
  1. Glycolysis.
  2. The Kreb's cycle.
  3. And the electron transport chain, to which the oxygen is mandatory or required.

Viktor [21]

Answer:

The correct answer is D)RNA polymerase

Explanation:

In DNA replication many enzymes and proteins are required to replicate a DNA template. For initiation of DNA synthesis the two DNA strands must be separated which is done by helicase.

Then primase adds short nucleotide sequence and initiate DNA replication. After that DNA polymerase acts and adds nucleotide at the 3' end of growing  DNA strand. Ligase is the enzyme that joins the two Okazaki fragments that are created in the lagging strand.

RNA polymerase is not required in DNA replication and it works in transcription therefore the correct answer is RNA polymerase.

24. Which organism would occupy the
Nadusha1986 [10]

Answer:

The organism to have maximum energy would be the algae since ii will be at the lowest level. so the answer is 'B'.

Explanation:

The pyramid of energy shows the flow of energy from one trophic level to other. The lowest trophic level is occupied by the producers. In this case algae acts as the producer. Krill acts as the primary consumer, followed by leopard seal as the secondary consumer and finally killer whale as the tertiary consumer. The <em>lowest trophic level </em> contains maximum energy.

As we go upwards, only 10% of the energy gets transferred to the next trophic level.

A sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar. Which of the foll
vaieri [72.5K]

Answer: C. The C horizon is very deep.

Horizons are the layers of soil develops as a result of soil formation. Horizon lies parallel to the earth surface. Each horizon differs from the other on the basis of amount or organic matter present, color of the soil, texture of soil and other components making up horizon, and amount and type of minerals present in the soil.

C horizon is the horizon that lies deeper region of the collective soil horizon. It consist of unweathered or partially weathered rocks or their aggregates. Therefore, it retains the original chemical composition of the parent rock. This results in the higher mineral content as compared to other horizons. This horizon also lacks the organic matter as no or very little decomposition activity of plant and animal matter takes place. Therefore, color of soil in this horizon in the absence of organic matter remains light.

Hence, a sample of soil from a C horizon is light brown in color and has a high content of a mineral called feldspar is because of the fact that the C horizon is very deep.
