In Labrador retrievers, the allele for black coat color (B) is dominant to the allele for brown coat color (b). However, if a lab has two copies of the recessive allele for a pigment-depositing gene (e), it can only have yellow coat color. In a cross of two doubly heterozygous black labs (BbEe x BbEe), what fraction of the next generation would one expect to be yellow

Answers

Answer 1

Answer:

4/16 or 1/4

Explanation:

This question involves two genes; one coding for coat color and the other for pigment color. The allele for black coat color (B) is dominant to the allele for brown coat color (b) while two copies of the recessive allele for a pigment-depositing gene (e) can only have yellow coat color.

In a cross between two heterozygotes (BbEe), the following gametes will be produced by each parent: BE, Be, bE and be. Using these gametes in a punnet square (see attached image), the fraction of the next generation (F2) expected to be yellow i.e. have the genotype (__ee) will be 4/16 or 1/4.

Which atom is involved in giving your heart energy to beat?
O carbon
O gold
O oxygen
O iron​

Answers

Answer:

Oxygen

Explanation:

-How fast the heart beats depends on the body's need for oxygen-rich blood. At rest, the SA node causes your heart to beat about 50 to 100 times each minute. During activity or excitement, your body needs more oxygen-rich blood; the heart rate rises to well over 100 beats per minute.

-The heart, like any organ, requires blood for oxygen and other nutrients so it can do its work. The heart does not gather oxygen or nutrients from the blood flowing inside it. Instead, it receives blood from coronary arteries that eventually carry blood into the heart muscle.

What is the best explanation for the difference in shape between the two drops shown below

Answers

Answer:

A

Explanation:

I think the answer is A because Hexane is a non-polar solvent and A is the only answer choice that says its non polar. Im sorry if it is incorrect

The best explanation for the difference in shape between the two drops given in image is - Option D. glycerin is polar and has greater cohesion than hexane.

Polarity is the physical characteristics of liquid that allows them to stick to other substances which is called adhesion. Polar molecules also attracted to itself, and this physical trait called cohesion. Water's most common form in the air, a droplet is formed due to this cohesion.

Hexane is a nonpolar solvent that has less electro negativity charge therefore, they do not have hydrogen bonding and there is less cohesion in the molecules.Glycerin is a polar solvent that allows its molecules to attract itself that is cohesion present and lead to more of droplet shape.

Thus, the correct answer is - option D.

What is the relationship between Distance and average number of species?

Answers

Answer: The relationship between species and distance is that more distance or space has more species and less space has less species.

Explanation:

It can easily be understood by taking the example of the island in such a way that the larger islands contains more species than smaller islands.

There are a  diversity of species seen in a bigger islands, more in number and more in variety.

It is very important for the studying the various species and its conservation, protection and other factors.

So, more is the distance , more will be the number of species.

Why would mutation of a tyrosine residue to glutamate in the intracellular portion of a growth factor receptor lead to increased tumor formation

Answers

Answer:

this mutation leads to a constitutively active state where the receptor can not be inactivated by dephosphorylation  

Explanation:

Phosphorylation is a posttranslational modification that usually occurs at the side chains of serine, tyrosine and threonine residues, thereby regulating protein function. Phosphomimetic amino acids are substitutions (mutations) able to mimic the phosphorylated form of the protein, resulting in constitutive activation/inactivation of the corresponding protein. In this case, it is expected that the substitution of tyrosine to glutamate gives rise to a constitutively active state of the receptor by replacing tyrosine with a phosphomimetic residue.

Answers

Answer:

Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.

The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.

Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.

A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.

1.How does Nitrogen cycle through the enviroment?
2. Trace the steps that carbon cycles from plants,animal,and enviorment?​

Answers

Answer: 1. The nitrogen cycle is a biogeochemical cycle.

2. The carbon cycle is a biogeochemical cycle.

Explanation:

1. The nitrogen cycle can be defined as the biogeochemical cycle in which the atmospheric nitrogen is utilized by the plants which is fixed by the soil bacteria. The nitrogen becomes the part of the biosphere as plants utilize it as an important development mineral. The nitrogen cycle involves the nitrogen fixation in which plants fix nitrogen by the help of bacteria into ammonia, nitrification in which the ammonia is converted into nitrite, nitrogen assimilation in which the plants assimilate and utilize the nitrogen for their growth and development, and denitrification involves the reduction of nitrite into atmospheric nitrogen. The conversion of nitrogen is carried out via physical and biological processes.

2. The carbon cycle involves the atmospheric carbon dioxide being circulated in plants as they utilize it for photosynthesis. The carbon dioxide is fixed by the plants in the form of carbohydrate which is consumed by the animals and on decomposition of plants and animals dead matter release carbon dioxide gas to the atmosphere. This allows the recycling of the carbon dioxide gas in the environment.

Zara had a birthday and was able to choose a pet. The pet that she chose was a beautiful clownfish named Bozo, a common salt water fish. Zara already has a tank with goldfish at home. Use your knowledge of diffusion & osmosis to tell Zara how to take care of Bozo.

Answers

Answer:

See the answer below

Explanation:

The advice I would give  to Zara would be that she should keep Bozo in a separate tank with common salt water away from the goldfish. Bozo is a salt water fish while the goldfish can only survive in freshwater.

If Bozo is kept in a saltless water/freshwater tank with the goldfish, the water would be hypotonic to Bozo. Consequently, water will osmotically diffuse into the cells of Bozo, the cells would become turgid and lyse, and this would lead to the death of the fish.

If the goldfish is kept in the same salt water tank with Bozo, the salt water would be hypertonic to the goldfish. Consequently, water will osmotically diffuse out of the cells of the goldfish into the surrounding salt water, the cells of the goldfish would become flaccid, and this would lead to the death of the fish.

B. Fungicides to treat affected crops and planting rust-resistant varieties
C. Citrus greening to prevent the spread of rust
O D. Insulation using green roofs to limit rust

Answers

Answer:

B. Fungicides to treat affected crops and planting rust-resistant varieties

Explanation:

Leaf rust is a disease caused by the fungus Puccinia triticina which affects leaves, stems and grains in wheat and related cereals (i.e., barley and rye). This disease is known to affect crops in moist conditions. Leaf rust disease is spread through fungi spores from infected wheat plants to healthy plants. Recently, leaf rust-resistant varieties have been developed by crop improvement programs aimed at introducing leaf rust-resistant (lr) genes involved in resistance against this important crop disease. Moreover, there are different types of fungicides (e.g., Prothioconazole and Tebuconazole) used for chemical control of this disease.
