Dr. Sanchez and her team have observed an unusual star in the Andromeda galaxy. Their data suggests that the star is being consumed by a nearby black hole. They write a scientific paper about their work and submit it to a scientific journal. Other scientists read their paper and look for the unusual star as well. The other scientists are participating in which activity?
Answer:
so the answer is peer review
Explanation:
Yes, other scientists are participating in this activity not in a direct way but in an indirect way. The scientists are participating in peer review.
What is galaxy?The scientific paper was written by scientists which provide the data and conclusion of entire experiments. To write scientific experiments we need to collect data, frame hypotheses, research methodology, and find out the conclusion are some of the steps to writing a scientific paper.
Testing hypotheses often involves designing experiments. In the given experiment Dr. Sanchez found that star is consumed by a nearby blackhole. But other scientist found the unusual star as well.
This suggests that both scientist thought on different aspect. This suggest peer review.
Therefore, Yes, other scientists are participating in this activity not in a direct way but in an indirect way.

In the late 1800s, a biologist studying animal embryos coined the phrase "ontogeny recapitulates phylogeny," meaning that the physical development of an animal embryo (ontogeny) seemed to retrace the changing form of the species during its evolutionary history (phylogeny).
Why would embryonic development retrace evolutionary steps?
Answer:
Embryo provides information about their ancestors.
Explanation:
Embryonic development retrace evolutionary steps because embryo provides evidence for evolution as embryo formation in widely-divergent groups of organisms are conserved. This embryo provides information that leads to their ancestors from which they evolve so we can say that embryonic development provides evidence for evolution of an organism.

C: P Arm - Short Arm Structure
D: Q Arm - Long Arm Structure
E: DNA Molecule
F: Chromatids
Explanation:
The X chromosome does more than determine sex. We inherit one copy of each chromosome from each parent, and the different versions of genes present on each copy, called alleles, help determine our individual characteristics.

1. How does your DNA differ from other peoples?how is it similar
2.How does your DNA differ from a strawberries DNA? How is it similar
Answer:
1.DNA is more than 99% similar between any two people. All the differences in how we look, feel, behave and the differences in our health are due to less than 1% difference
2.In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA that means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see.
Explanation:
For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?
a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) Diffusion: it is a passive trans-membrane transport mechanism.
b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.
Which of the following are examples of stimuli?
Check all that apply.
-the strong smell of a woman's perfume
-the sour taste of a lemon
-pinching your skin
-dimming the lights in a room
-having your back massaged
Answer:
The answer is all of them
Explanation:
This is the answer because I’m a genius. You’re Welcome
Examples of stimuli are the strong smell of a woman's perfume, the sour taste of a lemon, pinching your skin, dimming the lights in a room, and having your back massaged. The correct options are a, b, c, d, and e.
What are stimuli?Humoral stimuli, hormonal stimuli, and neurological stimuli are the three basic types of stimuli that cause the endocrine glands to produce and release hormones.
With changes in the concentration of extracellular fluids, the humoral stimulus governs hormone release.
The strong smell stimuli the sense organs and sour taste stimuli our tongue and pinching in the skin gives stimuli to obtain that someone pinched pour skin
The neural stimuli allow hormone production straight from the glands.
Therefore, the correct options are a, b, c, d, and e.

Which best describes the relationship between digestion and cellular respiration? O A. Digestion breaks foods down to simple sugar molecules, and respiration uses the sugar molecules to produce energy. O B. Digestion creates nutrients from food particles, and respiration uses the nutrients to produce energy. O C. Digestion releases oxygen molecules from food, and respiration uses oxygen molecules to produce energy. D. Digestion produces waste materials, and respiration uses the waste materials to produce energy.
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products

45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?
Answer:
Explanation:
Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.
The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.
The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.
Which of the following describes Mendel's law of segregation?

What are ethical issues?When a particular action, scenario, or judgment conflicts with the moral standards of a society, there is an ethical problem. Since any of their actions could be questioned in terms of ethics, both people and companies could be implicated in these disputes.
These problems can arise in a person's interactions with other people or in their interactions with organizations, and the same is true for organizations.
These disputes can occasionally be legally risky since certain potential solutions may go against the letter of the law. In other cases, the problem might not have legal repercussions, but it might cause a backlash from outside parties.
Therefore, Harassment, Corruption, and Unfair treatment of Workers.
