Does the amount energy from food eaten by each organism equal the amount of energy used but each organism?
Answer:
Ecosystem follows the 10% law.
Explanation:
The amount of energy that is available in the ecosystem is equal and same is equally distributed. Plants use solar energy and convert it into usable energy for processing food and water in tissues and reproduction and root development. Later on when the plant dies or is eaten up the dead organic matter is converted to energy that is derived by the herbivorous or primary consumer. When then (90%) lost through respiration and digestion, waste generation in the body. After which the energy left may be again taken up by some secondary consumer and only 10% energy remains while the rest is diffused in the ecosystem and environment. Thus energy is neither created nor destroyed but transformed in its form.help asap please!!

Explanation:
A certain species of trilobite is known to have lived 300 million years ago. If this index fossil was found in a rock layer containing other fossils, what could you infer about the other fossils
a The rock layer killed the trilobite and the other fossils
b The other fossils are about 300 million years old
c The organisms that formed the other fossils are still living.
d The rock layer formed before the trilobite and other organisms
Answer:
b The other fossils are about 300 million years old
Explanation:
From the description of the problem given, we can correctly conclude that the other fossils are about 300 million years old and even the rock layers formed around that period in time too.
Fossils are the preserved remains of organisms that has once lived. Through the principle of relative dating we can determine the age of fossils and those of other related ones. According to the principle of fossil and fauna succession, "fossils succeed one another in a predetermined form". So, the fossils occurring together within the rock layers are of the same age.How are cells the basic unit of structure and function in the human body?

Explanation:
Which of the following facts implies that humans and fish had a common ancestor? A. Both species have the ability to swim. B. Both species must expel waste materials. C. Both species have gill slits when they are embryos. D. Both species are consumers.
Answer:
A common ancestor of humans and fish denotes the most recent organism, from which both the humans and fish have been evolved. Humans and fishes are vertebrates, which possess spinal column or backbone. Along with this, human embryos also go through a stage, during which they have gill-slits like structures in their neck as present in fish embryos.
These structures do not found in mature humans like fishes, but they support the fact that the humans share a common ancestral organism with fish.
the correct answer is option D). both species have gill slits when they are embryos.
Answer:
D= Both species are consumers.
Explanation
which phase do chromatids divide and cell contents begin to be divided?
Answer:
anaphase stage
Explanation:
All of the chromatids are split in sync as the cell enters the anaphase stage. It is to be mentioned that the genetic material from prophase was called the chromatids not chromosomes (if you haven’t noticed it by now). However, since the sister chromatids are split in anaphase the genetic material is once again referred to as chromosomes.

A character in an old movie wears a hat made out of aluminum foil in order to protect his brain from being influenced by the government’s thought-controlling rays. This is an example of delusions of __________.
A.
influence
B.
persecution
C.
grandeur
D.

It occurs whenever you believe somebody is mistreating, scheming against, or intending to harm you or a loved one.
Delusions of persecution:In an ancient film, a character wears an aluminum foil hat to shield his brain from the government's mind-controlling beams. Persecution delusions are evident in this case.
There have been a variety of delusions. Persecutory hallucinations are the most frequent. It occurs when you believe someone is abusing, conspiring against, or threatening to harm themselves or a loved one. Grandiose delusions are another type in which you have an overly high opinion of yourself or your accomplishments.Therefore, the final answer is "Option B".

Which of the following explains why meiosis contributes to genetic variations?
A - it increases the ratio of mitosis within an organism
B - It produces offspring that are different from either parent
C - It decreases the rate of mutation occurrence
D - It forms DNA that is resistant to environmental changes
Answer:
A
Explanation:
The reason of why meiosis contributes to genetic variations is because of option A. it increases the ratio of mitosis within an organism.
Why does meiosis contributes to genetic variations?Since the recombination and the non-dependent assortment in meiosis, each gamete comprise the different DNA set. It generated the unique combination of genes that should lead to zygote.
Also, it rises the mitosis ratio within an organism
Hence, the option A is correct.

Which of the following best describes the genetic complement in each
daughter cell at the conclusion of meiosis?
A. A haploid set of chromosomes that are a recombination of the
parents' chromosomes
B. A diploid set of chromosomes that are identical to the parents'
chromosomes
C. A diploid set of chromosomes identical to the other daughter cells'
chromosomes
D. A haploid set of chromosomes that are identical to the parents'
chromosomes
Answer:
A
Explanation:
Meiosis end in four daughter cells that are haploid and contain half the chromosomes as the parent cell and genetically different from the parent cell and from each other, so A would be the right answer.
A haploid set of chromosomes that are a recombination of the parents' chromosomes best describes the genetic complement in each daughter cell at the conclusion of meiosis.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Moreover, meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells.
Meiosis is important for three main reasons: it allows sexual reproduction of diploid organisms, it enables genetic diversity, and it aids the repair of genetic defects.

Suppose that this population of mice has stabilized so that both white and brown appear. White mice survive better in the winter and brown mice survive better in the warmer months. If a group of these mice migrated to an area that didn't get snowy in the winter, what do you think would be the long term effect on the color of these mice? Explain why.
Answer:
The population of the white mice would significantly decrease, and most of the mouse population would be with brown fur.
Explanation:
As stated in the question, the brown mice survive better in warmer times. This is due to the fact that with winter and snowy times it makes it harder for prey to spot the WHITE mice v.s. the BROWN mice who would very easily be spotted by the prey in snowy regions.

A) The sun heats up Earth's surface.
B) Water vapor condenses into water droplets.
C) Water does not soak into the ground.
D) There is a small amount of precipitation.
Explain why.
Answer: Runoff occurs when there is more water than land can absorb. The answer you’re looking for is C.
Explanation: The excess liquid flows across the surface of the land and into nearby creeks, streams, or ponds. ... Glaciers, snow, and rain all contribute to this natural runoff. Runoff also occurs naturally as soil is eroded and carried to various bodies of water.

how do homologous structures develop
Answer:
Explanation:
Homologous structures are structures that are similar in related organisms because they were inherited from a common ancestor. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor.the existence of homologous structures adapted to different purposes as the result of descent with modification from a common ancestor.

Which type of precipitation is most likely to occur when both air and cloud temperatures are above freezing?
A) Rain
B) Snow
C) Hail
D) Sleet
Answer:
it should be A or rain to be specific
Answer:
rain
Explanation:
If the ar is above freezing, the precipitation will most likely be rain. If the air is below freezing, the precipitation will most likely be snow. When air temperature is only a few degrees above freezing, precipitation may fall as sleet. Hail is most commonly formed within the cumulonimbus clouds of thunderstorms.
