Answer:
1. (d) A site, P site, E site
2. (d) is attached to the tRNA occupying the A site
3. (d) It is catalyzed by peptidul transferase
Explanation:
1. The functional ribosome inititiation complex, have three sites that bind tRNAs: the aminoacyl (A) site, the peptidyl (P) site and the exit (E) site. Initiation occurs with binding of the fmet-tRNA at the P site. Afterwards, once elongation is underway, tRNAs involved in the process occupy the three sites in the following order: A site, P site, E site.
2. The formation of a peptide bond during protein synthesis involves the transfer of an amino acid bound to the tRNA at the P site to the amino group of a second amino acid at the A site. When a peptide bond is formed between two amino acids, one is attached to the tRNA occupying the P site and the other is attached to the tRNA occupying the A site.
3. The formation of a peptide bond during protein synthesis is catalyzed by the enzyme peptidyl transferase.

When exercising routinely, timing the food that you eat around your exercise activities is important. Carbohydrate intake is particularly influential, with different ideal timings for simple carbohydrates and complex carbohydrates. The best types of carbohydrates to eat during and/or immediately after exercise are simple carbohydrates, whereas complex carbohydrates are ideally consumed a couple of hours before exercise. Complex carbohydrates take longer to digest and enter the bloodstream and can help build glycogen stores.
Sort the following food items into their respective bins based on whether they are simple, complex, or noncarbohydrate-rich foods.
Drag the appropriate items into their respective bins

How does the process of meiosis affect the genetic information of an
offspring?
Answer: All the offspring receive identical genetic information
Meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. This means that the gametes produced through meiosis exhibit an range of genetic variation.

How would a change to the sequence of nucleotides in a DNA segment affect the mRNA transcribed from the DNA?
Answer:
It would change the nucleotide sequence of the transcribed mRNA
Explanation:
During the process of transcription, a DNA template is used to synthesize a mRNA molecule. The nucleotides in the DNA molecule undergo a complementary base pairing to form the nucleotides on the mRNA. This means that the order of sequence on the DNA determines the order of sequence on the mRNA.
In a case where the nucleotide sequence of a DNA segment changes in the process of MUTATION, the sequence of nucleotides in the mRNA strand will also change. For example, if sequence: ATT on the DNA produces UAA on the mRNA, a change to AAT on the DNA will cause the mRNA sequence to change to UUA.
Answer:
A change of the sequence of nucleotides in a DNA segment is called a mutation. This could change whether certain proteins are made that support the body or not.

If you resection the lower spinal cord of a cat such that the nerves to the hind legs are isolated from the brain, and the cat is still able to walk on a treadmill, you have demonstrated that motor commands must have originated in the lower portion of the spinal cord. This is evidence for the existence of ___________.
Answer:
Central pattern generators
Explanation:
A central pattern generator (CPG) is a neuronal circuit consisting of neurons localized in the spinal cord capable of producing rhythmic outputs. CPGs are able to produce rhythmic movements even when the spinal cord is separated from the brain and sensory organs. CPGs are the main components of motor functions including, among others, breathing, flying, chewing, walking, swimming, etc. These neural circuits have been discovered in almost all vertebrates studied to date.

Answer:
D.
Explanation:
For two organisms to breed successfully and produce viable offspring that are fertile, both must belong to the same species with the same number of chromosomes.
Postzygotic barrier often occur when two organisms of different species and chromosomes numbers mate. If successful, the hybrid they produce remain sterile. This is what happens when goat with chromosome number of 60, mates with sheep with chromosome number of 54.
Postzygotic barrier is responsible for the sterility of the hybrid they produce, as a result of difference in chromosome number between sheep and goat.

DNA replication is said to be semiconservative. Which of the following statements correctly explains what this means?
Answer: DNA is a double stranded molecule. When DNA is copied the two strand of DNA (old strands) separate and new nucleotides match up with the two separated strands.
This process creates two identical double stranded DNA molecules are formed. Each DNA molecule contains one strand of the original DNA molecule and one newly synthesized (made) strand.
Explanation: https://youtu.be/Gxoyr8JKc4w
Hope this helps :D
The semi-conservative nature of DNA replication illustrates that each strand in the DNA double helix function as a template for the synthesis of a new or complementary strand.
What is DNA replication?DNA replication may be defined as a type of biological process that deals with the synthesis of two identical replicas of DNA from one original DNA molecule during cell division.
The semi-conservative model of DNA was proposed by Watson and Crick. This model implies that each double helix of DNA is composed of one new and one old strand.
In semi-conservative replication, the parental double helix is half conserved and each parental single strand remains intact.
Therefore, DNA replication is said to be semi-conservative due to the process of each new double strand consisting of one parental strand and one new daughter strand.

Based on fossil data, the researcher estimates that humans and their most closely related species in the data set diverged approximately seven million years ago. Using these data, calculate the rate of mtDNA percent divergence per million years between humans and their most closely related species in the data set. Round your answer to two decimal places.
Answer:
Hello your question is incomplete attached below is the complete question
answer : = 1.25
Explanation:
i) Determine the rate of mtDNA percent divergence
From the data given the most closely related specie is Chimpanzee ( 8.8 sequence difference )
Note : Given that this divergence took place seven million years from now
∴The rate of mtDNA percent divergence per 1 millions years
= 8.8 / 7 = 1.25
The rate of mtDNA percent divergence per million years between humans and their most closely related species in the data set is 1.25.
As per observation the rate of mtDNA percent divergence per million years between humans and their most closely related species in the data set is given by the as chimpanzee is most close with 8.8. the rate of mtDNA percent divergence per million years is :
8.8/7= 1.25.
What is evolution ?An evolution is the rate of change in environment due to events occuered.
Thus it is well expained.

On the planet Kermit, in the Muppet population, there are two autosomal loci of interest. The first locus has alleles A and a, and the second locus has alleles B and b. A and B are the dominant alleles at the respective loci. The loci act in an epistatic manner, identical to the way two genes interact to produce coat color in labradors. The phenotype here is muppet hair color. We have the following results:
Muppet hair color as a function of two-locus genotypes
