I think the correct answer would be the first option. The best method to use in order to measure the distance of  star would be to calculate the variations in the position of the star due to movement of Earth in its orbit. The doppler shift which is what is being described in the last three options does not calculate the distance rather it calculates the relative velocity. The method used in measuring the distance was introduced by Edwin Hubble where he found that relative velocity of a body in space is directly proportional to the distance of that body from Earth.

Lerok [7]
Well, ask yourself, "Do I try hard enough?" "Was it the best I could do?" And well if the answer is yes, then you have nothing to stress out about too much. Maybe talk to your teacher and ask for extra credit. Get tutoring. Talk to a guidance counselor. If none of that helps, well then you're just not the best at the subject, but just try your best. In the future, you won't even remember about all those grades! Coming from a 6th grader, the beginning of the year was super hard. I'm not the best at math, but I'm very good at Language Arts. Everyone has their own weaknesses and strengths. Don't worry about it.

The Prostate gland

The prostate is a walnut-sized organ that surrounds the first part of the urethra. It is located between the bladder and the penis. Semen is formed by the prostate by combining a thick white fluid it initially produced with the sperm from the testicles. It also produces an antibiotic protein known as prostate-specific antigen (PSA) that changes the semen into liquid.

The viral pathogen that causes cold sores can remain inactive in the body for a long time between disease outbreaks. How is this
Serhud [2]

This disease is classified as a latent disease.

<h3>Classification of diseases</h3>

Latent disease is a classification of disease whereby the infectious agent remains inert in the body of its host between episodes of recurrent diseases.

Examples of viral pathogens that causes latent diseases include:

  • <em>Herpes simplex, </em>

  • <em>Varicella zoster, </em>

  • <em>Epstein-Barr</em>,

  • <em>Human cytomegalovirus, </em>

  • Adenovirus, and Kaposi's sarcoma.

The infection caused by the listed viral pathogens exhibit a latent disease phase whereby there is no noticeable symptoms of infection.

What level of protein structure is created during protein syntheisis?
Zolol [24]

Answer:

The correct answer will be - Primary structure

Explanation:

Proteins are one of the biomolecules formed by the process of translation.

Depending on the function they attain many structures like primary, secondary, tertiary and Quaternary structure.

The primary structure is the simplest structure formed by binding the amino acids via peptide bonds in linear order. This simplest structure is formed by the process of translation in which tRNA brings specific amino acids to the nascent peptide.

Thus, Primary structure is the correct answer.
