Ok what is it the you need help with
The answer is B. A chemical reaction consists of an endothermic stage (energy taken in to break chemical bonds) followed by an exothermic stage (energy released as bonds are formed). The first stage requires this energy input, which is the activation energy. When the activation energy is reached or exceeded, the reaction will occur. Therefore as soon as this threshold is REACHED, it happens
Answer:
The correct answer is - wobble; the curvature of the anticodon loop; inosine.
Explanation:
The wobble phenomenon or hypothesis tells that why there are multiple codons are present for a single amino acid. 20 amino acids are coded by 61 codons. It states that tRNA can identify and attach to more than one amino acid due to the curvature of the anticodon loop.
The curvature of the anticodon loop is that the base at the 1st position on the anticodon to binding but the less-precise base pairs that can arise between the 3rd base of the codon. The inosine is the nucleoside that presents in a position in the curvature of the anticodon loop and its position responsible for wobble as well.
Answer:
Random distribution.
Explanation:
The distribution of the population in space across an area is largely driven by the food and other resources in the environment. Uniform, random and clumped are the main distribution pattern.
The grass is distributed randomly in the environment, the population of deer is most likely to have random distribution pattern. Since, the distribution pattern depends upon the food resources so the deer have random distribution in space.
Thus, the correct answer is option (D).
Answer:
A) Tissue
Explanation:
Cells are the basic and fundamental units of all living organisms. Plants, like every other multicellular living organisms, are composed of cells that perform different functions. A group of cells that perform similar functions make up or form TISSUES, tissues that work together form the ORGAN, organs that work together to perform same function form the ORGAN SYSTEM.
In plants, sieve tubes and companion cells work together to carry out a similar task in plants, which is to transport nutrients and sugar inside the plant. Since sieve tubes and companion cells work together to fulfil same task, they collectively form a tissue in plants called PHLOEM tissue.
