The breathing rate of an aquatic animal is more than that of of a terrestrial animal . Why ?
Answer:
Since the amount of oxygen dissolved in water is comparatively lower than that in air, the aquatic animals have to breath rapidly to take in sufficient oxygen. Thus, the rate of breathing in aquatic organisms is much faster than that seen in terrestrial organisms
Cross a heterozygous black rabbit with a heterozygous black rabbit. What is the
Genotype Percentages? What is the Phenotype Percentages? (How many will be
black, How many white? Percentages of BB Bb & bb)
Explanation:
Bb x Bb
1BB, 2Bb, and 1 bb
Let B=black fur allele(dominant) and b=white fur allele(recessive),
¾ of the rabbit will be black while ¼ will be white.
Hence,
¾×100%=75%
¼×100%=25%

Human cells have 46 chromosomes. Each chromosome consists of a pair of identical chromatids attached together by a structure called a centromere. Once the chromosome has split, each chromatid is called a daughter chromosome. At the end of cytokinesis, how many daughter chromosomes will be found in each cell? Explain.
Answer:
92 daughter chromosomes.
Explanation:
There are 46 chromosomes in a normal cell and each chromosome turns into 2 daughter cells. So 46 plus 46 is 92.

Caroline set up a fourth test tube that contained a leaf and was exposed to dim
light.
After two hours the colour of the indicator solution in this test tube remained orange.
Explain why.

Answer: The NEGATIVE CONTROL is the
test tube that is filled with ONLY distilled
water.
Explanation:
A negative control of an experiment is
carried out alongside the main primary
experiment except that the treatment is
changed to something that is predicted
to have no result. In the negative
control, the student does not expect any
response. This would help the student
compare the result of a new experiment
against an already known existing results.
Analysing the experiment carried out
by the student, She filled two test tubes
with distilled water and placed a piece
of Elodea in one of the tubes, leaving
the other without a plant. The other test
tube that contains only distilled water is
the negative control because she wasn't
expecting any result from it. It's also
served as a control sample to the primary
experiment. This is observed as she
blew in each tube to add carbon dioxide,
which caused the distilled water to
become more acidic. This would help the
student know that the that experimental
results are valid and to ensure that time is
saved

1. Using Mendel's Law of Segregation and Law of
Independent Assortment, explain how meiosis leads to genetic variation.
Answer:
Homologous chromosomes can independently assort along the metaphase plate during metaphase 1, meaning it doesn't not matter the order in which they line up, making it have more diverse possibilities. The law of segregation says that one allele from a gene can go to either gamete randomly, therefore there are 4 genetically different gametes from each parent that can be formed and come together to form a genetically diverse person.
Explanation:
describe some of the adaptation of insects that allows them obtain their food from other organisms
Answer:
Parasitism
Explanation:
An example of this would be parasitism. It is a way in which some insects get food from other animals by living inside a host. It is a relationship in which the other animal is damaged while the parasite (in this case the insect) benefits.
How are fungi classified?
Explanation:
Fungi are eukaryotic organisms that include microorganisms such as yeasts, moulds and mushrooms. These organisms are classified under kingdom fungi.
The organisms found in Kingdom fungi contain a cell wall and are omnipresent. They are classified as heterotrophs among the living organisms.
Which pair of traits is most likely to be inherited together?
A. purple eye and brown eye because they are both eye traits
B. aristaless and speck body because they have the greatest chance of crossing over
O
C. curved wing and arc (bent wings) because they have the least chance of crossing-over
D. black body and light eye because they are closest together on chromosome 2
Answer:
D
Explanation:
The closer together two genes are on a chromosome, the less likely their alleles will be separated by crossing-over.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question.
Part B - Whats the students scientific question?
Part C - Construct at least two possible hypotheses for the students experiment
Part D - Choose one hypotheses to make a prediction
Part E - How would you conduct your investigation? In your answer, explain your independent and dependent variables.
Part F - How does the design of your experiment control for outside factors that may affect the results?
Part G - How do you plan to analyze and communicate your results?

Why is farming good for the society? (Economic growth related) please give me scientific questions, I will mark you as brainly. Thank you
Answer:
Agriculture gave people the opportunity to create civilizations, fight hunger and work to combat challenges in population growth and climate change.
Explanation:
Another positive development in farming is the rapid expansion of farmers markets. Farmers markets allow small farmers to interact directly with consumers. The food system remains within the local economy by being locally produced and eliminates the need for long-distance transportation. The opportunity to purchase locally grown food proves invaluable as the demand for it rises.

if you have been to a beach for a whole day, then you have seen tides roll in and out. What causes
Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Answer:
it's caused by the gravitational forces from the moon.
Explanation:
grew up at the beach

what hormone do the c-cells secrete, and what is the function of this hormone?
Answer:
Calcitonin is one of those critical hormones. Calcitonin is a hormone that the C-cells in the thyroid gland produce and release. It opposes the action of the parathyroid hormone, helping to regulate the blood's calcium and phosphate levels. How does calcitonin work?
The hormone that the c-cell secrete is calcitonin. The function of calcitonin is a hormone that regulates the amount of calcium in your blood by decreasing it.
What are hormones?The important hormone is calcitonin. Calcitonin is a hormone produced and released by the thyroid gland's C-cells. It works in opposition to the activity of the parathyroid hormone, assisting in the regulation of calcium and phosphate levels in the blood.
Calcitonin is a hormone produced by the thyroid gland, which is a tiny, butterfly-shaped gland found near the throat. Calcitonin regulates how the body uses calcium.
Calcitonin is a cancer marker. Tumor markers are substances produced in the body by cancer cells or normal cells in response to cancer.
Thus, calcitonin is the hormone secreted by c-cells. Calcitonin is a hormone that controls the quantity of calcium in your blood by reducing it.
