The best and worst possible outcome and the long-term effect on the cell if mRNA strands were miscopied is that the cell will not make functional proteins from that mRNA strand. The best and at the same time worst possible outcome is that the cell will not make functional proteins from the mRNA strand.<span>

Answer:
A. Natural selection results in those individuals within a population who are best-adapted surviving and producing more offspring. The traits that promote survival are heritable.
Explanation:
Natural selection works on the genetic variations that are already present in the natural populations. Some organisms of a population are more likely to produce more offspring than the others. This is due to the presence of beneficial genetic traits in these individuals that impart survival and reproductive fitness to them. Natural selection favors those individuals. Over the generations, the frequency of the beneficial genetic trait in the population increases.
Answer: Lets choose a food processing company for scientific study.
Explanation:
Scientific study is the study which involves taking observations on the samples being studied experimentally. Drawing evidences from observations to prove a scientific fact.
In a food based company, several scientific tests are required to be done to check the shelf-life, quality, quantity of the ingredients, and to check whether they are fit for consumption or not all of these parameters have to checked through experimental procedures.
The right option is; d. consumers
All animals are consumers
Consumers are organisms that usually feed on other organisms or organic matter in order to gain energy because of their inability to manufacture their food from inorganic sources. All animals are consumers and they are also known as heterotrophs. There are different types of consumers. They include; primary consumers (herbivores e.g. goats, cows), secondary consumers (carnivores e.g. wolves, crocodile), and tertiary consumers (large carnivores e.g. eagle, lion)
Answer & explanation:
Amylase is part of enzymes, a group of large peptide molecules (formed by amino acids) whose role is to catalyze reactions in order to facilitate the synthesis of other biological molecules.
Amylase is found mainly in saliva (in the form of salivary amylase, or ptialin), acting in the breakdown of starch and glycogen in foods, reducing them to smaller particles, facilitating their digestion and absorption.
The action of enzymes depends on certain specific conditions, called optimal conditions. In the case of <u>amylase</u>, it depends on an optimum pH of 7 (neutral) and an optimum temperature of approximately 37 ° C.
This enzyme can still act between 35 ° C and 40 ° C, but below 35 ° C it is inactivated, preventing its functions from being performed, and above 40 ° C it suffers denaturation, causing changes in its structures.
Thus, it is concluded that the <u>temperature</u> (under optimal conditions) is important for enzymes because it keeps their actions and structures in proper operation.
