Answer & Explanation:
Chromosomes in an animal are thread-like structures located inside the nucleus of the cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from parents to offspring, DNA contains the specific instructions that make each type of living creature unique.
A particular triplet of bases in the template strand of dna is 5' agt 3'. The corresponding codon for the mrna transcribed is
The corresponding codon for the mRNA that is transcribed is referred to as 3'-UCA-5'.
What is a Codon?This is defined as a trinucleotide sequence of DNA or RNA that corresponds to a specific amino acid.
During transcription, the corresponding base for Adenine is Uracil, cytosine is to guanine and Thymine is to Adenine and 5'3' to 3'5'.

The corresponding codon for the mRNA transcribed is 3'-UCA-5'. The corresponding mRNA lacks the nucleotide base thymine (T).
What do you mean by mRNA?mRNA may be defined as the molecules that carry the genetic information needed to make proteins.
During transcription, the template strand of DNA is transformed into the mRNA in the nucleus of the cell. mRNA consists of nucleotide bases Adenine, Guanine, Cytosine, and Uracil. Hence, the sequence of the strand gets reversed according to the template strand of the DNA.
Therefore, the corresponding codon for the mRNA transcribed is 3'-UCA-5'.

In the Hardy-Weinberg principle, the actual number values of p and q will not change if five specific conditions are being met. This indicates
Question 1 options:
evolution is occurring only because of mutations
evolution is not occuring
evolution is occurring rapidly because of climate change
evolution is occurring because of natural selection
In the Hardy-Weinberg principle, the values of p and q will not change if evolution is not occurring.
What is the Hardy-Weinberg principle?The Hardy-Weinberg principle is a model used in population genetics to estimate genotypic and allele frequencies in a population.
The Hardy-Weinberg principle states that allele and genotypic frequencies remain constant in absence of evolutionary forces.
These evolutionary forces include nonrandom mating, gene drift, gene flow, mutation and natural selection.

10.A 600 kg great white shark is lurking below an observation cage. His movement is
being studied from a series of motion sensors below the boat. The shark leisurely
charges the cage, strikes it and makes the cage rattle. Later, the shark returns for
another run at the cage. The shark strikes the cage with 12,800 N of force. The
shark traveled for 10 m in making its run. The cage is designed to withstand
124,500 J of "work" before it breaks. Should the man in the cage be worried?
Explain.
The work done by the shark is 128000 J which is greater than the maximum force the cage can withstand (124500 J), the man in the cage should be worried.
What is work done?Work done is the product of force and the distance covered by the force.
Mathematically;
Work done = Force × distanceThe unit of work done is Joules.
The work done by the shark is calculated as follows:
Work done = 12800 × 10
Work done = 128000 J
Maximum force the can withstand = 124500 J
Since the work done by the shark is greater than the maximum force the cage can withstand, the man in th cage should be worried.

Due to a genetic modification, a mouse has no horizontal cells in its retinas. What impact will this have on the mouse’s vision?
Answer:
Below
Explanation:
Horizontal cells are the laterally interconnecting neurons having cell bodies in the inner nuclear layer of the retina of vertebrate eyes. They help integrate and regulate the input from multiple photoreceptor cells. Without them you wouldn't be able to see color, which means the mouse won't process color.
Due to a genetic modification, a mouse has no horizontal cells in its retinas and it does not expresses the connexin26.
What is horizontal cells?
The horizontal cells has receptive field with the neurobiotin and controlled by the electrical coupling.
Horizontal cells are the laterally interconnecting neurons having cell our bodies withinside the internal nuclear layer of the retina of vertebrate eyes. They assist combine and alter the enter from a couple of photoreceptor cells.

what is the difference between segregation and independent assortment? Will give brainiest award/ 72 points
Answer:
The Law of Segregation states that the members of each pair of alleles separate when gametes are formed. A gamete will receive one allele or the other. The Law of Independent assortment states that two or more pairs of alleles segregate independently of one another during gamete formation, so basically the Law of Independent Assortment, also known as "Inheritance Law", means that the inheritance pattern of one trait will not affect the inheritance pattern of another.
