Synergist is the  term refers to a muscle that shares the same action as another muscle at the same joint

What do you call paired muscles?

These types of muscles are referred to as antagonistic pairs. When two muscles are antagonistic, the lengthening or relaxing of one muscle causes the other to relax. The term "agonist" refers to the muscle that is contracting, while "antagonist" refers to the muscle that is relaxing or extending.

Synergistic muscles are sets of muscles that cooperate to produce a single action. Antagonistic muscles are those that oppose one another. Movement requires an antagonist muscle to counteract the action of an agonist muscle.

which of the following answers describes a component that is present in prokaryotic organisms? pick all that apply

Answers

Prokaryotic organisms are unicellular organisms that lack a nucleus and other membrane-bound organelles. They are found in the domains Bacteria and Archaea.

There are many components present in prokaryotic organisms. Some of them are discussed below:

Cell wall: This is a tough, protective layer that surrounds the cell membrane in bacteria and archaea. The cell wall is made up of peptidoglycan in bacteria and other materials in archaea.

Flagella: It is a whip-like structure that is used by many prokaryotic cells to move. The flagellum rotates like a propeller, allowing the cell to swim through liquid environments.

Pili or fimbriae: These are short, hair-like structures that extend from the surface of many prokaryotic cells. They are used for attachment to surfaces or other cells.

Capsule: It is a protective layer that surrounds the cell wall of some prokaryotic cells. The capsule is made up of a gel-like material that helps the cell to avoid being engulfed by immune cells such as macrophages.

Ribosomes: They are the site of protein synthesis in prokaryotic cells. Ribosomes are made up of two subunits that come together to form a functional ribosome.In conclusion, components that are present in prokaryotic organisms are cell wall, flagella, pili or fimbriae, capsule, and ribosomes.

Animal Bites of Postal Workers In Cleveland, a sample of 75 mail carriers showed that 8 had been bitten by an animal during one week. In Philadelphia, in a sample of 55 mail carriers, 14 had received animal bites. Is there a significant difference in the proportions? Use a = 0.10 and use p₁ for the proportion of mail carriers in Cleveland. Find the 90% confidence interval for the difference of the two proportions and round all intermediate calculations to at least three decimal places.

Answers

The 90% confidence interval for the difference of the two proportions is CI ≈ (-0.282, -0.014)

The null hypothesis:

H0: p1 - p2 = 0

The alternative hypothesis:

Ha: p1 - p2 ≠ 0

Significance level α = 0.10

Use p₁ for the proportion of mail carriers in Cleveland. Use n1, p1, and q1 for the sample proportion, sample size, and sample proportion for Cleveland.

Similarly, use n2, p2, and q2 for the sample proportion, sample size, and sample proportion for Philadelphia.

p1 = 8/75 = 0.1067

n1 = 75

q1 = 1 - p1 = 0.8933

p2 = 14/55 = 0.2545

n2 = 55

q2 = 1 - p2 = 0.7455

Pooled proportion:   P = (p1n1 + p2n2) / (n1 + n2)

P = (0.1067 × 75 + 0.2545 × 55) / (75 + 55)

= 0.1836

Standard Error of the Difference:  

σd = √(P(1 - P)(1/n1 + 1/n2))

σd = √(0.1836(1 - 0.1836)(1/75 + 1/55))

≈ 0.0815

The test statistic:

z = (p1 - p2) / σd

z = (0.1067 - 0.2545) / 0.0815

≈ -1.8117

Critical values:

For a two-tailed test, using α = 0.10, we need to find zα/2 such that P(-zα/2 < Z < zα/2) = 1 - α.

Therefore, α/2 = 0.05

z0.05 = 1.645

Rejection region:

Reject H0 if z < -z0.05 or if z > z0.05

Test conclusion:

Since z = -1.8117 is between -1.645 and 1.645, we fail to reject the null hypothesis.

Hence, there is no significant difference in the proportions of mail carriers who receive animal bites in Cleveland and Philadelphia.

The 90% confidence interval for the difference of the two proportions:

CI = (p1 - p2) ± zα/2 σd

CI = (0.1067 - 0.2545) ± 1.645 × 0.0815

CI = -0.1478 ± 0.1340

CI = (-0.2818, -0.0138)

Rounding to at least three decimal places: CI ≈ (-0.282, -0.014)

Contrast the roles of tRNA and mRNA during translation and list all enzymes that participate in the transcription and translation process. [FYI, You must name the enzyme unless it is part of a class of enzymes like transcription factors, in that case just name the class it belongs to. For example, instead of saying "Transcription factor II comes in at step 2 to perform…", you can say "An initiation factor comes in at step 2 of initiation to perform…"]

Answers

Aminoacyl-tRNA synthetases ,  Initiation factors ,  Elongation factors and  Release factors are list all enzymes that participate in the transcription and translation process.

During translation, mRNA serves as a template for protein synthesis while tRNA brings in the amino acids that match the mRNA codons. The mRNA carries the genetic information from the DNA in the nucleus to the ribosome where it is translated into a protein. The tRNA molecules, on the other hand, carry the specific amino acids to the ribosome and match them to the codons on the mRNA.

Enzymes that participate in the transcription process include RNA polymerase, which synthesizes the mRNA from the DNA template, and helicase, which unwinds the double-stranded DNA molecule to expose the template strand. Another enzyme involved is topoisomerase, which relieves the tension caused by the unwinding of the DNA.

Enzymes that participate in the translation process include aminoacyl-tRNA synthetases, which attach the correct amino acids to their corresponding tRNA molecules, and peptidyl transferase, which catalyzes the formation of peptide bonds between amino acids. Initiation factors help to assemble the ribosome, elongation factors help to add new amino acids to the growing polypeptide chain, and release factors help to release the completed polypeptide from the ribosome.
Hi there! During translation, tRNA and mRNA have distinct roles. mRNA serves as the template that carries genetic information from DNA and provides the sequence of codons needed for protein synthesis. In contrast, tRNA is responsible for recognizing and carrying specific amino acids to the ribosome to match the codons on the mRNA.

In the transcription and translation process, various enzymes and protein factors play important roles. For transcription:

1. RNA polymerase: This enzyme synthesizes the mRNA by adding RNA nucleotides complementary to the DNA template.

2. Transcription factors: These proteins help regulate the transcription process by binding to specific DNA sequences and assisting RNA polymerase in initiating transcription.

During translation, there are several enzymes and factors involved:

1. Aminoacyl-tRNA synthetases: These enzymes attach specific amino acids to their corresponding tRNA molecules, forming aminoacyl-tRNAs.

2. Initiation factors: These proteins facilitate the assembly of the ribosome, mRNA, and initiator tRNA at the start codon to begin translation.

3. Elongation factors: These proteins assist in the addition of amino acids to the growing polypeptide chain and ensure the correct positioning of tRNA and mRNA on the ribosome.

4. Release factors: These proteins recognize the stop codon on mRNA and promote the termination of translation, releasing the completed polypeptide chain.

a woman and man who are not hemophiliacs get married and have two hemophiliac sons, two hemophiliac sons, two sons without hemophilia, and four daughters without hemophilia. after the death of this husband, she marries a hemophiliac man. how would the children of the second marriage compare to those of the first?

Answers

Given that the second marriage's father carries the hemophilia mutation, the children of the second marriage will have a more significant chance of acquiring the disease than the children of the first marriage.

Their girls have a 50% chance of inheriting the hemophilia mutation and becoming carriers like their mothers, and all of their sons will have the disease.

Steps

The absence of hemophilia in the couple's first union indicates that at least one X chromosome in each partner is normal and free of the hemophilia mutation. The following genotypes could apply to their offspring:

Sons without hemophilia: X^N Y (where N represents the normal allele)

Hemophiliac sons: X^h Y (where h represents the mutant allele)

Daughters without hemophilia: X^N X^N or X^N X^h (since females have two X chromosomes, they can inherit either a normal or a mutant allele)

We can conclude from the information that the lady carries the hemophilia mutation and can pass it on to her boys. No sons of the previous marriage suffered hemophilia, thus the husband must have had a healthy X chromosome.

The fact that the man is hemophiliac in the second marriage indicates that he carries a mutation on one X chromosome that causes hemophilia. The following genotypes could apply to their offspring:

Sons with hemophilia: X^h Y (since all sons inherit their X chromosome from their mother and their Y chromosome from their father)

Daughters without hemophilia: X^N X^h (since daughters inherit one X chromosome from each parent, and the father can only pass on the X chromosome with the hemophilia mutation)
