Answer:
1- A
2- 4
3- A with T
G with C
T with A
Explanation:
The nucleic acid is made up of five major nitrogenous bases. These nitrogenous bases are adenine (A), guanine (G), thymine (T), and cytosine (C). Adenine is always paired with thymine, and guanine is always paired with cytosine. These are known as base pairs. Uracil is only present in RNA, by replacing thymine.
The researcher hypothesizes that the FXR1 gene codes for a protein that binds to mRNAs that encode some of the proteins that damage arteries. Individuals with a particular mutation of the FXR1 gene tend to have high levels of these proteins. Based on this information, predict how the FXR1 protein most likely interacts with the mRNAs.
Answer:
it is expected that FXR1 interacts with mRNAs by inhibiting them before they are translated into the ribosomes, thereby preventing the production of proteins that cause damage in the arteries.
Explanation:
The translation is the cellular process in which a messenger RNA (mRNA) is used as template to synthesize a protein in the ribosomes. During translation, ribosomes catalyze the reaction that joins amino acids in order to create a polypeptide chain (i.e., an ordered sequence of amino acids). Diverse types of either synthetically or naturally occurring molecules can inhibit protein production at the level of translation (e.g., siRNAs, proteins, drugs, etc). In this case, it is expected that FXR1 inhibits the mRNAs that encode proteins capable of causing damage in the arteries, thereby a mutation that results in reduced and/or abolished FXR1 function (i.e., a loss of function mutation) will lead to a phenotype with high levels of these proteins.
Binding of FRX1 protein to mRNA will block the translation process of mRNA, thereby inhibiting protein synthesis.
What is the function of mRNA in protein synthesis?mRNA or messenger RNA is made from the transcription of DNA and the information stored in it is translated into amino acids by ribosomes in the process of protein synthesis.
Thus, mRNA serves as a template for protein synthesis.
How does the FRX1 protein interact with mRNA?The binding of the FRX1 protein will most likely block access to the codons present in the mRNA from being read by tRNA, thus inhibiting the synthesis of the proteins that damage arteries.
Therefore, binding of FRX1 protein to mRNA will block the translation process of mRNA, thereby inhibiting protein synthesis.

How does genotypic variation occur?
Answer:
Genotypic variation occurs when alleles are randomly sorted during sexual reproduction. ... Some types of organisms can increase genetic variation through reproduction. They are able to combine the genetic material of two parents, rather than copying the genetic material of a single parent.

Answer:
Light energy is absorbed by chlorophyll. C
Explanation:
Answer:
Light energy is absorbed by photosynthesis
Explanation:
Photosynthesis takes place in two stages: the light-dependent reactions and the Calvin cycle. In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water.
Which of the following is a accurate depiction of primary ecological succession?
Answer:
This question lacks options, however, primary succession will be explained for detailed comprehension.
Explanation:
Ecological succession is the gradual series of changes that occurs in an ecosystem, charging it's structure and composition over time. It is of two types namely; primary and secondary successions.
Primary succession is characterized by the "LACK OF NO SOIL". It begins on a barren piece of land e.g rocks, with no form of life previously known to colonize the area. In primary succession, the barren land is first colonized by organisms such as lichens etc., which are collectively regarded to as PIONEER SPECIES.

Answer:
Bioindicators
Explanation:
Answer:
Indicator species and/or keystone species
Explanation:
Indicator species are species (e.g., plants, animals, fungi) that can be utilized to determine changes in the environment. An indicator species can show the impact of pollution on an ecosystem. For example, mosses are indicator species that indicate the acidity in the soil. Moreover, keystone species are species that maintain the ecological balance in the ecosystem. When a keystone species is removed, the entire ecosystem is dramatically changed or may even cease to exist altogether. In consequence, keystone species can be used to define an entire ecosystem. For example, bees are a keynote species that contributes to balance the ecosystem by pollinating plants.
