Evaluate each of the statements below. Select those that accurately describe the role of genes and chromosomes in the process of inheriting a specific trait. Choose ALL that apply. A) Chromosomes are made of DNA. B) There are 26 pairs of chromosomes in humans. 09 Alleles are the different forms of a gene that can exist. D) Chromosomes contain genes that control the inheritance of traits. E) Genes are made of chromosomes and contain all of the genetic information for an organism.
Answer:
A) Chromosomes are made of DNA
C) Alleles are the different forms of a gene that can exist
D) Chromosomes contain genes that control the inheritance of traits.
Explanation:
Chromosomes are long molecules of deoxyribonucleic acid (DNA) that contain part (or all) of the genetic material of an organism. Humans contain 46 chromosomes organized in 23 pairs of homologous chromosomes (22 pairs of autosomal chromosomes and one pair of sex chromosomes, X and Y). Moreover, a gene is a physical segment of a chromosome that contains the information to encode a protein. Alleles are different forms of a gene (i.e., gene variants) that may be caused by mutations or genetic recombination. Humans are diploid organisms (2N: 46), and therefore we have two copies of each gene (alleles), one on each homologous chromosome.
Using all the words below, write a short paragraph explain convection currents
Convection Currents
Mantle
Crust
Heat
Less dense
movement
More dense
Explanation:
Convection currents are the result of differential heating. Lighter (less dense), warm material rises while heavier (more dense) cool material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.In the atmosphere, as air warms it rises, allowing cooler air to flow in underneath. Along with the turning of the Earth, this movement of air creates winds. Winds, in turn, create surface waves on the ocean.Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents.Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.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.

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%)

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

Explanation:
I believe this would be a difficult organism to use in the study of genetics, because for years all Lionesses have looked extremely similar to us humans. While Male lions have a lot of differences from each other. Although, what could be studied is how they pass on their traits to their offspring.

root hair cells have a high ion concentration . explain how this is maintained and its importance
Answer:
Root hair cells are adapted for taking up water and mineral ions by having a large surface area to increase the rate of absorption. They also contain lots of mitochondria , which release energy from glucose during respiration in order to provide the energy needed for active transport.
Explanation:
To maintain the concentration gradient and so the constant movement of water into the root hair cell by osmosis, the root hair cell actively transports mineral salts into the cell.
Root hairs are important because they absorb the majority of the water and nutrients required by the plant. The root hair cell actively transfers mineral salts into the cell to maintain the high ion concentration.
Root hairs, also known as absorbent hairs, are outgrowths of epidermal cells, which are specialized cells found at the root's tip.Root hairs are important because they absorb the majority of the water and nutrients required by the plant. In legume plants, they are also directly involved in the production of root nodules.The root hair cell actively transfers mineral salts into the cell to maintain the concentration gradient and hence the continual passage of water into the cell by osmosis.
