A population of crabs living on a sandy beach exhibits three colors: dark brown, light

brown, and speckled. The genotypes for these colors are BB for dark brown, bb for light

brown, and Bb for speckled. If a dark brown crab were crossed with a light brown crab,

what would be the probable phenotypic ratio of their offspring?

Answers

Answer 1

Answer:

100% of the progeny will be speckled

Explanation:

Available data:

Three colors: dark brown, light  brown, and speckled.The genotypes for these colors are BB for dark brown, bb for light brown, and Bb for speckled.

Cross: dark brown crab  with a light brown crab

Parentals) BB     x     bb

Gametes) B   B        b    b

Punnett square)

                     B        B

            b      Bb      Bb

             b     Bb      Bb

F1) Genotype:

     4/4 = 100% of the progeny will be heterozygous for the trait, Bb

     Phenotype:

    4/4 = 100% of the progeny will be speckled

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

Answers

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.

Theophrastus , Carl Linnaeus , Aristotle, charakan . Find the odd one

Answers

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.

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

Which reservoir is found underground in the cracks and spaces in the soil, sand, and rock?

A) Glaciers
B) Ground water
C) Polar ice caps
D) Rivers

Explain Why

Answers

The answer is ground water
Explanation: first of all, it is in the name. Ground water is water that is found in the ground. Another idea to find the answer would be to do process of elimination.
A glacier is a moving mass or river of ice that is mainly found in Antarctica and Greenland. Polar ice caps are regions that are covered in ice. A river is a natural flowing source of water that flows towards an ocean, sea, lake or another river. Ground water is water located beneath the Earth’s surface and can be found in cracks and rock formations. By doing process of elimination, you can easily cross out the possibility that the answer is glaciers or polar ice caps because they both have something to do with ice. This leaves you with rivers and ground water. You can eliminate rivers because rivers can’t fit into cracks and spaces in the soil. This leaves you with your answer of ground water.
