In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.
1) what is the genotype of the spotted (recessive) parent?
Answer:
the spotted parent has the genotype ss
Explanation:
we will use s as the letter when describing the spotted trait.
since spotted is recessive, that parents have to have two little s to have the trait. Since the child also has that, we know that they will have the genotype ss. the child would have to get a little s from both parents, so the solid parent would have Ss, showing as solid, but still having the gene for spots.
mendel,s experiment is applicable not only in plant but also in animals
Answer:
Yes, this is true. This is because animals also carry genes which codes for a certain trait, and these traits have their own allele. Mendel's experiment portrayed tall plants and dwarf plants being crossed, moreover the colour of the flowers could also be taken as an example. In the similar way, animals, for example, mice, could be white furred or brown furred. They both carry alleles which codes for their fur colour, like plant alleles which codes for either tall or dwarf.

phosphates. It is the energy currency of the cell. ATP is used by organisms as energy...th
that require energy.
Which statements regarding the ATP-ADP cycle are true?
ATP synthesis takes place in the mitochondria of eukaryotic cells.
The given question is incomplete as the group of choices are not given, however, the choices are associated with the question is given below:
ATP synthesis takes place in the mitochondria of eukaryotic cells.
ATP is regenerated from ADP through the process of phosphorylation.
energy is stored in the covalent bonds between phosphates, with the greatest amount of energy in the bond between the second and third phosphate groups.
most of the readily available energy stored in ATP is stored during the manufacture of adenosine.
the ribose sugar in the model above is the direct product of photosynthesis.
Answer:
The correct answer is given below:
Explanation:
ATP synthesis takes place in the mitochondria cell organelle in the eukaryotic cells, however, a small part of ATP generation takes place in other cell regions but most of the ATP synthesis is occurs in the inner membrane of mitochondria which makes it energy house of the cell.
ATP is formed by the addition of phosphorus to ADP and this process is called phosphorylation.
Each bond of the adenosine and its three phosphates has stored energy in their covalent bonds. The last two phosphates have a high amount of energy in their bond.
BRAINLIEST: In dolphins, to have spots on the skin is a recessive trait. One spotted dolphin and one solid gray dolphin have a baby spotted dolphin. Go through the following steps to figure out the genotype of the parent dolphins.
1) what are the POSSIBLE genotypes of the solid grey dolphin?
2) what is the genotype of the baby spotted dolphin?
Answer:
1) Ss
2) ss
Explanation:
Spots (recessive) - s
No spots (dominant) - S
So the possible combination to get a baby spotted dolphin may be: Ss and ss
Punnett Square:
| S | s |
s | Ss | ss |
s | Ss | ss |
So the genotype of the Solid gray dolphin might have been a dominant allele and a recessive allele, which is Ss.
Moreover the genotype of the spotted baby dolphin might me ss.
In order for high force crossbridges to form in contracting skeletal muscle, calcium must a. bind to calmodulin to phosphorylate the myosin. b. phosphorylate the tropomyosin which moves it. c. phosphorylate the troponin to move the tropomyosin. d. bind to tropomyosin which moves the troponin. e. bind to troponin which moves the tropomyosin.
Answer:
e. bind to troponin which moves the tropomyosin.
Explanation:
Troponin (Tn) is a protein complex composed of three different proteins: troponin C (TnC), troponin I (TnI), and troponin T (TnT). This complex is found both in skeletal muscles and cardiac muscles, where TnC attaches calcium ions through four and three calcium ion-binding sites, respectively. When a muscle is relaxed, Tn attaches to tropomyosin to prevent muscle contraction. During muscle contraction, calcium channels open and cytosolic calcium ions bind to TnC, thereby Tn changes its conformation and moves the tropomyosin. This process relieves the inhibition of the interaction between actin and myosin filaments, which makes muscle contraction possible.

what is HIV in full
Answer:
Human Immunodeficiency viruses
HIV Overview
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome).
There is currently no effective cure. Once people get HIV, they have it for life.
But with proper medical care, HIV can be controlled. People with HIV who get effective HIV treatment can live long, healthy lives and protect their partners.
History of HIV
HIV infection in humans came from a type of chimpanzee in Central Africa.
The chimpanzee version of the virus (called simian immunodeficiency virus, or SIV) was probably passed to humans when humans hunted these chimpanzees for meat and came in contact with their infected blood.
Studies show that HIV may have jumped from chimpanzees to humans as far back as the late 1800s.
Over decades, HIV slowly spread across Africa and later into other parts of the world. We know that the virus has existed in the United States since at least the mid to late 1970s.
To learn more about the history of HIV in the United States and CDC’s response to the epidemic, see CDC’s HIV and AIDS Timeline.
How do I know if I have HIV?
The only way to know for sure whether you have HIV is to get tested. Knowing your HIV status helps you make healthy decisions to prevent getting or transmitting HIV.
Are there symptoms?
Graphic listing symptoms of HIV: Fever,HIV Symptoms and Testing, Chills, Rash, Night sweats, Muscle aches, Sore throat, Fatigue, Swollen lymph nodes, and Mouth ulcers.
Some people have flu-like symptoms within 2 to 4 weeks after infection (called acute HIV infection). These symptoms may last for a few days or several weeks. Possible symptoms include
Fever,
Chills,
Rash,
Night sweats,
Muscle aches,
Sore throat,
Fatigue,
Swollen lymph nodes, and
Mouth ulcers.
But some people may not feel sick during acute HIV infection. These symptoms don’t mean you have HIV. Other illnesses can cause these same symptoms.
See a health care provider if you have these symptoms and think you may have been exposed to HIV. Getting tested for HIV is the only way to know for sure.
What are the stages of HIV?
When people with HIV don’t get treatment, they typically progress through three stages. But HIV medicine can slow or prevent progression of the disease. With the advancements in treatment, progression to Stage 3 is less common today than in the early days of HIV.
Stage 1: Acute HIV Infection
Stage 1: Acute HIV Infection
People have a large amount of HIV in their blood. They are very contagious.
Some people have flu-like symptoms. This is the body’s natural response to infection.
But some people may not feel sick right away or at all.
If you have flu-like symptoms and think you may have been exposed to HIV, seek medical care and ask for a test to diagnose acute infection.
Only antigen/antibody tests or nucleic acid tests (NATs) can diagnose acute infection.
Stage 2: Chronic HIV Infection
Stage 2: Chronic HIV Infection
This stage is also called asymptomatic HIV infection or clinical latency.
HIV is still active but reproduces at very low levels.
People may not have any symptoms or get sick during this phase.
Without taking HIV medicine, this period may last a decade or longer, but some may progress faster.
People can transmit HIV in this phase.
At the end of this phase, the amount of HIV in the blood (called viral load) goes up and the CD4 cell count goes down. The person may have symptoms as the virus levels increase in the body, and the person moves into Stage 3.
People who take HIV medicine as prescribed may never move into Stage 3.
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
Stage 3: Acquired Immunodeficiency Syndrome (AIDS)
People with AIDS have such badly damaged immune systems that they get an increasing number of severe illnesses, called opportunistic infections.
People receive an AIDS diagnosis when their CD4 cell count drops below 200 cells/mm, or if they develop certain opportunistic infections.
People with AIDS can have a high viral load and be very infectious.
Without treatment, people with AIDS typically survive about three years.
Which one of the following is the largest source of greenhouse gases in the atmosphere? A. the burning of fossil fuels B. chemicals released during manufacturing C. the release of carbon dioxide from cellular respiration D. Deforestation

PLEASE HELP!!! How many ATP can we get from one molecule of phosphocreatine?
a.1
b.2
c.10
d.32
Phosphocreatine is a chemical compound that provides high energy to the skeletal muscles. One molecule of phosphocreatine produces one ATP molecule. Thus, option a is correct.
What is phosphocreatine?The phosphocreatine system is a way to generate ATP and energy in the body (muscles). During muscle contraction, the phosphocreatine yields a phosphate molecule that in turn produces ATP.
The phosphocreatine system provides quick and fast energy in the form of ATP molecules through the anaerobic system that does not require oxygen. It gives its phosphate group to ADP to produce ATP as,
ADP + phosphocreatine → ATP + Creatine
The ATP-PC system yields only one molecule per phosphocreatine at a very fast rate for the muscles to utilize when doing any exercise or physical activity that involves contraction and relaxation.
Therefore, phosphocreatine produces 1 ATP.

How might green spaces help reduce the negative impact that humans have on Earth’s water supply?
It would give nature a place to fight back, and become more healthy, and less hindered. Cities mess up the evaporation cycle, and because of parks, the water is able to be soaked up by grass, and then released through evaporation. When it rains over a city, the water goes into gutters, and becomes more polluted.

Answer:
1. Biosphere
2. Ecosystem
3. Community
4. Population
Explanation:
The correct graphical representation of the organization levels of a biological system is as follows:
Cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and biosphere. What is the level of organization of the biological system?The level of the biological system may be defined as the arrangement of structures that are usually characterized by relationships with things at higher levels that are being composed of things at the next lower level. A cell is the smallest level of organization for living things while the biosphere is the highest level of organization for living things.
A cell is the basic structural and functional unit of living organisms. The collection of cells gives rise to the formation of tissues which are combindly known as organs. Organs give rise to the organ system that completely formed a living entity.
