Answers

Answer 1

Answer:

As temperature increases, absolute brightness increases

Explanation:

As temperature increases, absolute brightness increases

Answer 2

As temperature increases, absolute brightness increases. Therefore, option (C) is correct.

What is absolute brightness?

Absolute brightness, also known as absolute magnitude, is a measure of the intrinsic luminosity of a star, which is its total energy output per unit of time. Absolute brightness is defined as the brightness a star would have if it were placed at a standard distance of 10 parsecs (32.6 light years) from Earth. This standard distance allows astronomers to compare the luminosity of stars with different distances from Earth.

Absolute brightness is an important measure for astronomers because it helps them determine the true luminosity and size of a star. It also helps astronomers classify stars based on their luminosity and temperature, which is related to their evolutionary stage. For example, main sequence stars, which are stars in the process of burning hydrogen to helium, are classified based on their temperature and absolute brightness

what is NOT an example of proof of the existence of the emdosymbiotic theory in modern day mitochondria?

a. Mitochondria has its own DNA
b. Mitochondria have their own nucleus
c. Mitochondria has it's own membrane
d. Mitochondria has its own ribosomes ​

Answers

Answer:

The correct answer is - option B. mitochondria have their own nucleus.

Explanation:

Endosymbiotic theory is a evolutionary theory which explains how eukaryotic cells evolved from prokaryotic organisms.

Evidences of endosymbiotic theory are:

1. Mitochondria and chloroplasts are double membrane bound cell organelles. The inner membrane probably evolved from the plasma membrane of engulfed bacterium and outer membrane from the plasma membrane or endoplasmic reticulum of the host cell.

2. Almost similar size of mitochondria and chloroplast and bacteria and their ribosomes.

3. Cristae of mitochondria resemble the folded membranes is groups of bacteria.

4. Mitochondrion and chloroplast both have circular DNA similar to those of bacterial DNA.

Explain the difference between sex hormones and glandular stimulating hormones

Answers

Answer:

Sex hormones are those hormones that within the endocrine system of the human being, are considered more directly involved in human sexuality, particularly in the processes of copulation and reproduction.On the other hand, glandular stimulating hormones are those that act on hormonal production in another endocrine gland, that is, they are stimulants, since they stimulate the corresponding glands.

Explanation:

Sex hormones are chemical substances secreted by the sex endocrine glands (the testes and ovaries) and subsequently released into the bloodstream, to be transported to the organs on which they exert their action (increasing or decreasing their activity).The production of hormones is regulated in many cases by a negative feedback system, which causes an excess of a hormone to be followed by a decrease in its production. The glandular stimulating hormones are transported to the blood to stimulate the corresponding glands (thyroid, adrenal cortex, and gonads) and these will be the ones that secrete various types of hormones (thyroxine, corticosteroids and sex hormones, respectively), which in addition to acting in the body, they feed back into the pituitary and hypothalamus to inhibit their activity and balance the respective secretions of these two organs and the target gland. For example, follicle-stimulating hormone encourages sperm production in men and stimulates the ovaries to release eggs in women. Luteinizing hormone and follicle stimulator work together to allow normal function of the ovaries or testicles.

A scientist uses radioactive nitrogen to label the nitrogenous bases of the DNA of a cell. Then the DNA is allowed to replicate, and the new strands take up non-radioactive bases. Do one, both, or neither of the daughter cells have radioactive DNA? Explain.

Answers

I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.

Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.

Sorry if im wrong

Answer:

I would say one..

Explanation:

It says the new strands take u non-radioactive bases.. if he only used the radioactive to label one of them then I would say one..

What kind of mutation would occur if a sequence of DNA is changed from ATCGGCTTAACG to ATCGGCTAAACG?

Answers

Answer:

Base substitution mutation

Explanation:

Mutation is the alteration or change that occurs to the sequence of a gene caused by a mutagen (chemicals) or spontaneously-induced. Depending on how the mutation occurs, it is of different types. The mutation shown in this question is as follows:

ATCGGCTTAACG to ATCGGCTAAACG

This type of mutation is called SUBSTITUTION MUTATION. Substitution mutation is a type of mutation that involves the replacement of one or more nucleotide base by another. In this original sequence; ATCGGCTTAACG, the eight base T was replaced by base A in the sequence, hence, it is a substitution mutation.

Over 30 children younger than three years of age developed gastroenteritis after visiting a local water park. These cases represented 44% of the park visitors in this age group on the day in question. No older individuals were affected. The causative agent was determined to be a member of the bacterial genus Shigella. The disease resulted from oral transmission to the children. Based only on the information given, can you classify this outbreak as an epidemic? Why or why not? If you were an epidemiologist, how would you go about determining which pools in the water park were contaminated?

Answers

Answer:

No this is not an outbreak

Explanation:

No it cannot be classified as outbreak because an outbreak is when the number of affected individuals in an epidemic is much higher as compared to the estimated values. However, an epidemic is the one that affects the people around different countries of the globe.

This can be considered as endemic that is restricted to a certain set of people in a community

I would have studied pattern of movement of affected kids. The common pool to which all these kids visited can be the infectious one. Also one can test the pathogen in infected kinds, and look for similar pathogen in pool water through testing.
