(b) Explain how the addition of a phosphate group to certain amino acids of Brec likely affects the tertiary structure and function of Brec. Explain how
the addition of a small RNA could prevent the activation of kinase D?
Answers
Answer:
Protein phosphorylation can activate/deactivate protein function, while small RNAs can be used for repressing translation of mRNAs through the RNA interference (RNAi) pathway
Explanation:
Protein phosphorylation is one of the most important posttranslational modifications (PTMs) that acts to activate, inhibit, or reversibly switch on/off protein function. Protein phosphorylation confers a reversible and versatile process that cells use to transmit signals and respond to environmental stimuli. This PTM is well known to modify the tertiary structure of the protein and thus activate/inhibit protein functions such as, for example, signaling pathways associated with protein interactions. In consequence, protein phosphorylation can be used by a cell to regulate Brec activity. On the other hand, small non-coding RNAs (ncRNAs) such as, for example, microRNAs (miRNAs), small interfering RNAs (siRNAs), and PIWI-interacting RNAs (piRNAs), are regulatory molecules that bind by complementary base pairing to messenger RNAs (mRNAs) in order to repress translation and/or trigger mRNA degradation through the RNA interference (RNAi) pathway. The RNAi pathway is widely used in molecular biology to silence genes of interest (for example, in this case, the gene that encodes for the kinase D protein).
1. Adding the phosphate group to the amino acid chains is known as phosphorylation. This attachment affects the tertiary arrangement and function of Brec.
Amino acids join together to form the protein that needs to be stimulated and deactivated for proper functioning.Protein phosphorylation is very crucial in post-translation modification.For protein function, it acts as an activator, inhibitor, reversibly on and offs the switch.Phosphorylation assures a reversible process to the cell to transmit signals for the cell functioning.Therefore, Brec activity can be controlled by the phosphorylation of proteins.2. Small RNA's are RNA fragments which is around 150 nucleotide in length.
Functionally significant small RNA's such as siRNAs, microRNAs scaRNAs and many other acts as regulatory molecules which target and adheres to the mRNA transcripts.This binding inhibits the translation process or degrades the mRNA by activating the RNA interference (RNAi) pathway.RNAi pathway is used to suppress the activation of the kinase D.To learn more about phosphorylation and small RNA follow the given link below:

The given question is incomplete as it lacks the options required to answer the question, however, options for the question is as follows:
A. Photosynthesis
B. Cellular respiration
C. both A and B
d. None of the above
Answer:
The correct answer is - option A. cellular respiration.
Explanation:
Plants produce their food or glucose with the help of the photosynthesis process. Plants called autotrophs as they generate their food on their own whereas animals depend on plants and other animals for their food and energy.
Plants and animals both perform cellular respiration in order to convert the food or glucose to the useable energy form that is known as ATP. Cellular respiration converts glucose into energy and releases carbondioxide and water.
The animals have the process of the Cellular respiration, to produce energy from the food they eat.
Cellular Respiration:
It is the process by which all organism perform to generate energy as ATP from the Glucose and produce Carbon dioxide as by product.
Cellular Respiration uses Oxygen and glucose as reactant to produce ATP.It is occur in the mitochondria. Photosynthesis is not found in animals as they lake Chloroplast.Therefore, the animals have the process of the Cellular respiration.

If the first trophic level in an energy pyramid receives 1,000 units of energy from the Sun, how much energy is available for the third trophic level?
Answers
Answer:
10 units
Explanation:
Energy is transferred from organism to organism in an ecosystem when they feed on one another. However, based on the pyramid of energy, only about 10% of energy is transferred from one organism to another because a bulk of energy (about 90%) has been lost to metabolic activities.
Energy moves from producers to consumers, each occupying trophic levels. If the first trophic level in an energy pyramid receives 1,000 units of energy from the sun,
- 10% of 1000units will be available for the second trophic level i.e. 10/100 × 1000 = 100units
- 10% of 100units will be available for the third trophic level i.e. 10/100 × 100 = 10units
Hence, 10units of energy is available for the third trophic level.

d. depressed core body temperature (hypothermia) caused by exposure to cold temperatures at high altitudes.
Answers
Answer:
The correct answer is - option C.
Explanation:
Skiing generally happens on higher altitudes such as mountains. It is known that there is less oxygen is available at higher altitudes. There is low oxygen pressure at such height.
The prolonged increase in heart and breathing rate is due to less oxygen available for the cells. This condition is known as hypoxia caused by insufficient blood hemoglobin to supply oxygen for physical activities at higher altitudes.

Answers
Answer:
the answer is 1), 2) and 3)
Explanation:
Metabolism can be defined as all the chemical reactions inside a cell that are required to carry out cellular functions (e.g., reproduction, growth, development). The metabolic reactions can be divided into anabolic and catabolic reactions. Anabolic reactions refer to metabolic reactions that require energy in order to construct new molecules from smaller ones (i..e., biosynthesis). Anabolism comprises endergonic metabolic pathways which are fueled by the use of energy (e.g., cellular ATP). On the other hand, catabolic reactions refer to metabolic reactions where larger molecules are separated to form smaller ones. Catabolic reactions are exergonic because they do not require energy (for example, reactions involved in cellular respiration).
How can gene flow, genetic drift, and natural selection all influence macroevolution?
Answers
Answer:
Macroevolution refers to large-scale evolutionary changes that break the species barrier and can give rise to new species and even affect higher taxonomic groups.The basic evolutionary mechanisms migration, genetic drift and natural selection can produce important evolutionary changes if given enough time.Large groups and macroevolutionary trends originate in gradual, adaptive stages, as a product of natural selection acting at the level of individuals , but operating for much longer periods of time.All depends on the mutations originating new alleles or genes, which imply the existence of very different characters from the pre-existing ones, and that these different characters are selected because they imply a better adaptation to the environment.
Explanation:
Macroevolution refers to the evolutionary changes that occur on a large scale, such as the genesis of high-ranking taxonomic groups: the appearance of species within their taxonomic groups, the appearance of evolutionary trends, the acquisition of anatomical characteristics that characterize the groups.For there to be an evolutionary change, then, new properties must emerge that constitute a new species. Evolution is a process of changes at the species level, distinct from those that occur in each individual organism. Gene flow is the transfer of alleles of genes from one population to another. Contributes to variation and diversity of individuals. Evolution is then the change of allelic frequencies over time.Macroevolution takes place through the process of natural selection, that is, the differential reproduction of individuals, and adaptive improvement over a very long period of time. This type of evolution is based on interpreting the appearance of new species or large groups, as well as mass extinctions, with the subsequent proliferation of new groups. The evolutionary changes that determine the origin of body plans are based on macromutations on which natural selection acts.
