Answer:
1. The species that can produce their food with the assistance of light energy coming from the Sun are termed as autotrophs. These species tend to produce chemical energy from light energy. Heterotrophs on the other hand refer to the species that lack the tendency of generating their food and are solely reliant upon the autotrophs for food.
2. The phenomenon that utilizes water and carbon dioxide and produces carbohydrates within the plants is known as photosynthesis. In the process, oxygen is also produced as a byproduct. The produced oxygen is further utilized by other species in the process of cellular respiration.
3. In the life of an organism, both oxidation and reduction perform an essential function. In the process of photosynthesis, the reduction of carbon dioxide is done and oxidation of water molecules is done. Therefore, it can be said that photosynthesis is an illustration of the oxidation-reduction reaction. Similarly, in cellular respiration, the molecules of oxygen are reduced and the molecules of glucose are oxidized, thus, it is also an illustration of an oxidation-reduction reaction.
4. In the light reaction phase of photosynthesis, the production of ATP, that is, the source of energy is done. Further in plants, the utilization of ATP is done to fix carbon dioxide within the glucose. In the process of cellular respiration, the energy within the carbohydrates is utilized to generate ATP at the time of the electron transport chain.
Option C:
B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3'
Explanation:
A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.
As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.
If we look at option B:
wild-type 5-AUG CAU ACA UUG GAG UGA-3
mutant 5’- AUG CAU ACA UCU GGA GUG A-3’
An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.
How large extinct animals were, at the time.
Answer:
C
Explanation:
This is placing a cell in hyper tonic solution.Therefore, the water potential of the cells is higher than the environment. Hence it lose water to the environment which has a lower water potential, but higher solute potential.
Therefore the loss of fluid by the cell leads to shrinking of the cytosol and it containing organelles. Later the cells collapse.

Esto es colocar las células en una solución hipertónica. Por lo tanto, el potencial hídrico de las células es mayor que el del medio ambiente. Por lo tanto, perder agua al medio ambiente reducirá el potencial hídrico, pero aumentará el potencial de soluto.
Por lo tanto, la pérdida de líquido por parte de la célula conduce a la contracción del citosol y que contiene orgánulos.
