Which section of the pre-mrna contains the protein-coding regions
Answers
The exons of the pre -mRNA contain the protein -coding regions.
Pre mRNA is the first made mRNA transcript and requires undergo many post transcriptional modifications for the formation of a mature mRNA.
The exons are the regions of the pre-mRNA that are found in the mature RNA, after the splicing of introns takes place.
RNA splicing is the process in which the non-coding segments of the RNA, which are known as introns, are removed by the help of small nuclear ribonucleoproteins. These SnRNPs make the spliceosome, which catalyzes the process of splicing.
After the introns are removed by the splicing process, the exons are covalently joined, which forms the mature mRNA.

A tonicity with a high concentration of solutes is said to be _________. isotonic selectively permeable hypertonic hypotonic
Answers
A tonicity with a high concentration of solutes is said to be Hypertonic.
Option (c) is correct.
The effective osmotic pressure gradient, or the difference in water potential between two fluids separated by a semi-permeable cell membrane, is measured by tonicity.
The relative concentration of specific, membrane-impermeable solutes across a cell membrane, which controls the direction and magnitude of osmotic flux, is what determines tonicity.
In comparison to other solutions, a hypertonic solution contains a higher concentration of non-permeating solutes.
A hypotonic solution contains fewer solutes than another solution.
When the effective osmole concentration of one solution and another solution match, the two solutions are said to be isotonic.
Hence, A tonicity with a high concentration of solutes is said to be hypertonic.

Answers
During a mumps outbreak at a local school, a teacher has been exposed. the client has previously been immunized for mumps, and consequently possesses acquired immunity.
What does acquired immunity means?
Acquired (adaptive or specific) immunity is not present at birth. It is learned. When a person's immune system comes into contact with foreign invaders and detects nonself substances, the learning process begins (antigens). The components of acquired immunity then discover the most effective strategy for combating each antigen and start to form a memory for that antigen. Specific immunity is another name for acquired immunity. Lymphocytes are the white blood cells that provide innate immunity (T cells and B cells).
After being exposed to a novel antigen for the first time, acquired immunity takes time to develop. However, subsequent reactions to the antigen are quicker and more efficient than those that followed the initial exposure because the antigen is recalled.

________ regulation occurs within a cell when the newly formed protein is modified.
Answers
Post-translational regulation occurs within a cell when the newly formed protein is modified.
What is Post-translational regulation?After being synthesized, folded, and put together, proteins can undergo post-translational modification. It has been shown that a variety of post-translational changes take place inside cells. Any alteration that can be made to a protein can also be undone. A post-translational alteration can take many distinct forms.
The process generally entails the formation of a covalent bond connecting a particular chemical group to a particular set of amino acid side chains on the protein. These groups can include phosphate groups (phosphorylation), acetate groups (acetylation), the attachment of lipid/hydrophobic groups (lipid modification), or carbohydrates (glycosylation). The majority of these post-translational changes are reversible; one enzyme adds the modifying group, and another enzyme can take it away.
For example, protein kinases phosphorylate proteins, while protein phosphatases remove such phosphate groups. Similar to allosteric effectors, post-translational changes alter the structure of the polypeptide to which they are bound, which therefore affects the polypeptide's activity. Additionally, they can alter a protein's stability, localization within the cell, and interactions with other proteins.

What is the most likely basis for future human evolutionary change?
Answers
The most likely basis for future human evolutionary change is technological change.
Evolution is a natural process that takes millions of years to occur. In this, an organism evolves on the basis of changing environment, living conditions, availability of food, living place and pattern, etc.
Natural selection works as an important force in this process as nature selects the fittest individuals which means nature selects those individuals who have the most appropriate genes according to the current conditions for survival to reproduce and pass those genes to the next generation.
The differences in the genes depend on an individual's ability to adapt to the changes in the environment and change their living style and habits accordingly to survive.
Therefore, in the current scenario, technology is heading to be the world leader and humans have to learn to adapt to the changes accordingly and evolve in the same way so that they better fit with the coming changes and can survive easily.

50% percentage of the offspring are predicted to be heterozygous for the f gene.
Heterozygous for F means one of the genes is F and the other f. As we can see from the square there is a 50% chance of the offspring has the heterozygous F gene.
If the two versions are one-of-a-kind, you've got a heterozygous genotype for that gene. For an instance, being heterozygous for hair color may want to suggest you have one allele for pink hair and one allele for brown hair. The connection among the 2 alleles impacts which tendencies are expressed.
Heterozygous is a nation of getting inherited one of a kind kinds of a specific gene from each one all your biological parents. Now, through distinct forms, we typically mean that there are different quantities of the gene in which the collection is distinct.
All of us have two alleles, or versions, of every gene. Being homozygous for a specific gene manner you inherited the same variations.

Looking like leafless branches of a tree, the _____ are the primary receivers of signals from other neurons, although the _____ also receives signals directly.
Answers
Looking like leafless branches of a tree, the dendrites are the primary receivers of signals, although the soma also receives signals directly.
Primary receivers of signals from other neurons:In order to enhance the surface area of the cell body, dendrites, which resemble tree-like extensions, are found at the beginning of neurons. These little protrusions relay electrical stimulation to the soma and take in information from neighboring neurons. Synapses are also found on dendrites.
Along its axon, the signal that is sent to other neurons travels. Even though a neuron may contain millions of dendrites, it will only have one axon. Axon terminals, the fourth separate component of a neuron, are located at the tip of the axon.

Answers
Intraneuronal effect on its effector organ is that it can excite or inhibit.
Some interneurons receive recurrent collaterals from axons (e.g., LMN axons) and project back onto the dendrites or cell body of origin of that axon, usually inhibiting that neuron. This process can help to regulate the excitability and timing of excitation of the target neurons.
The excitability of an interneuron network is bidirectionally controlled by distinct epochs of activity in principal cells. Examples of excitatory neurotransmitters include glutamate, epinephrine and norepinephrine.
