Plants get energy from sunlight. Why does most of the energy captured by plants never become available to herbivores?
Answer:
Because they lose most of the energy as heat when they perform metabolic activities
Explanation:
Cells of all living organisms require energy in form of ATP to perform their cellular functions. In an ecosystem, organisms obtain this energy by feeding on one another. However, these energy transfer starts from organisms capable of using sunlight called PRODUCERS e.g plants.
Herbivores, which are PRIMARY CONSUMERS get their energy by feeding on these plants. However, according to the PYRAMID OF ENERGY, which represents the flow of energy in an ecosystem, only a few portion of the energy (about 10%) derived by plants from the sun gets transferred to herbivores. This is because most of the energy (about 90%) is lost as heat when the plants undergo metabolic activities.
The majority of the energy captivated by the plants never become accessible to herbivores because of the 10 percent rule, that is, for each trophic level, only approximately 10% of the energy moves from one level to the next level.
• An animal, which primarily consume plants and its products is termed herbivore.
• The herbivores occupy the second level and consume producers, that is, the plants, thus, they are termed as the primary consumers.
• Approximately, 10% of the energy is passed from one level to the next, for each trophic level. This is known as the 10% rule.
• Due to this rule, the herbivores only get about 10% of the energy stored by the plants they consume.
Thus, due to 10% energy rule, the majority of the energy captured by the plants never become available to herbivores.

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.

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.

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:
Explain what the greenhouse effect is, use diagrams if you wish.
Include:
-Radiation from the sun absorbs earths heat
-Some emitted
-Trapped by the greenhouse
Answer:
See the answer below
Explanation:
The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.
The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.
A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.
This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

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.

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.
What is Jupiter sunlight availability?
Answer:
From an average distance of 484 million miles (778 million kilometers), Jupiter is 5.2 astronomical units away from the Sun. One astronomical unit (abbreviated as AU), is the distance from the Sun to Earth. From this distance, it takes Sunlight 43 minutes to travel from the Sun to Jupiter.
