Purple flower color (P) is dominant over white flower color (p) in pea plants. A heterozygous pea plant with purple flowers is crossed with another heterozygous pea plant with purple flowers.
What will be the phenotypes, and probabilities of their offspring?
Question 11 options:
75% purple and 25% white
100% purple
100% white
50% purple and 50% white
Answer:
75% purple and 25% white
Explanation:
When a punnett square is drawn to predict the phenotypes of the pea plants offspring:
- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)
- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)

what are protons and electrons are compressed into. Plz hurry
Answer:
The electrons in degenerate matter are compressed so closely together that they more-or-less behave as if the entire star is one huge quantum system. They form an electron gas, and behave very much like a highly pressurized fluid inside the star. (Protons and neutrons have their own quantum states, thank you.)
Answer:
They compress into neutrons.

Guysss please I need your help!!!
Answer:
Symptoms
Signs and symptoms of hemophilia vary, depending on your level of clotting factors. If your clotting-factor level is mildly reduced, you may bleed only after surgery or trauma. If your deficiency is severe, you may experience spontaneous bleeding.
Signs and symptoms of spontaneous bleeding include:
Unexplained and excessive bleeding from cuts or injuries, or after surgery or dental work Many large or deep bruises Unusual bleeding after vaccinations Pain, swelling or tightness in your joints Blood in your urine or stool Nosebleeds without a known cause In infants, unexplained irritability
Bleeding into the brain
A simple bump on the head can cause bleeding into the brain for some people who have severe hemophilia. This rarely happens, but it's one of the most serious complications that can occur. Signs and symptoms include:
Painful, prolonged headache Repeated vomiting Sleepiness or lethargy Double vision Sudden weakness or clumsiness Convulsions or seizures
Causes
When you bleed, your body normally pools blood cells together to form a clot to stop the bleeding. The clotting process is encouraged by certain blood particles. Hemophilia occurs when you have a deficiency in one of these clotting factors.
There are several types of hemophilia, and most forms are inherited. However, about 30% of people with hemophilia have no family history of the disorder. In these people, an unexpected change occurs in one of the genes associated with hemophilia.
Acquired hemophilia is a rare variety of the condition that occurs when a person's immune system attacks clotting factors in the blood. It can be associated with:
Pregnancy Autoimmune conditions Cancer Multiple sclerosis
Treatment
Several different types of clotting factors are associated with different varieties of hemophilia. The main treatment for severe hemophilia involves receiving replacement of the specific clotting factor that you need through a tube placed in a vein.
This replacement therapy can be given to combat a bleeding episode that's in progress. It can also be administered on a regular schedule at home to help prevent bleeding episodes. Some people receive continuous replacement therapy.
Replacement clotting factor can be made from donated blood. Similar products, called recombinant clotting factors, are manufactured in a laboratory and aren't made from human blood.
Other therapies may include:
Desmopressin. In some forms of mild hemophilia, this hormone can stimulate your body to release more clotting factor. It can be injected slowly into a vein or provided as a nasal spray. Clot-preserving medications. These medications help prevent clots from breaking down. Fibrin sealants. These medications can be applied directly to wound sites to promote clotting and healing. Fibrin sealants are especially useful in dental therapy. Physical therapy. It can ease signs and symptoms if internal bleeding has damaged your joints. If internal bleeding has caused severe damage, you may need surgery. First aid for minor cuts. Using pressure and a bandage will generally take care of the bleeding. For small areas of bleeding beneath the skin, use an ice pack. Ice pops can be used to slow down minor bleeding in the mouth. Vaccinations. Although blood products are screened, it's still possible for people who rely on them to contract diseases. If you have hemophilia, consider receiving immunization against hepatitis A and B
Explain how a mutation in a single cell can lead to the development of a
tumor and cancer ?
Answer:
the pace of the cell cycle speeds up as the effectiveness of the control and repair mechanisms decreases Uncontrolled growth of the mutated cells outpaces the growth of normal cells in the area
Explanation:
Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one
Answer:
Charakan
Explanation:
The odd one out would be Charakan.
Theophrastus, Carl Linnaeus, and Aristotle are all scientists that contributed to the science of classification of living organisms (taxonomy).
Aristotle was the first scientist to classify living organisms into plant and animal kingdoms based on the artificial system of classification.
Theophrastus was a student of Aristotle and he wrote a book, De Historia Plantarum, classifying about 480 plants.
Carl Linnaeus invented the binomial system of naming living organisms in which organisms are given two names - the species and the genus name.
Charakan has no known contribution to taxonomy. Hence, the name is the only odd one.

Think of some traits in people, plants, or animals. Describe one trait and tell whether you think the trait is a dominant/recessive, multiple allele, codominant, incompletely dominant, sex-linked, or polygenic trait.
Answer:
Non-Mendelian inheritance
Multiple alleles, incomplete dominance, and codominance
Explanation:
In the real world, genes often come in many versions (alleles). Alleles aren't always fully dominant or recessive to one another, but may instead display codominance or incomplete dominance.
The force of gravitational attraction between the Sun and Jupiter could be increased by reducing which of the following?
The mass of the Sun and Jupiter
The distance between the Sun and Jupiter
The speed of rotation of Jupiter
The amount of radiation put out by the Sun
Answer:
The distance between the Sun and Jupiter
Explanation:
The force of gravitational attraction between the Sun and Jupiter could be increased by reducing the distance between the Sun and Jupiter.
What is force of gravitation?The force of gravitation is the force of attraction between two objects that have mass. It is described by Newton's law of gravitation, which states that every particle attracts every other particle by a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.
This force is what gives rise to the phenomenon of gravity, which holds planets in orbit around stars and causes objects to fall toward the ground.

What will happen to the photosynthesis rate if you increase the intensity of light?
Increasing the light intensity increases the rate of photosynthesis until some other factor - a limiting factor - becomes in short supply. At very high light intensities, photosynthesis is slowed and then inhibited, but these light intensities do not occur in nature.
Explain how the nervous system works within your body as you go throughout the day. From waking, eating, going to school, extracurricular activities, and finally bed; state how the different parts of the nervous system work together to complete these tasks.”
Answer:
when you wake up the nervous system remembers to get dressed for school as well as eating the brain remembers to pick up a fork or spoon to eat, going to school the brain will remember what time the bus will come and when to go to the bus, doing extracurricular activities the brain will tell your arm to throw a football or kick a soccer ball, when going to bed the nervous system will tell the nerves in your arms to pull the blanket on top of you and to turn the light off.
