When a tall plant TT in pea is crossed with another tall plant TT the probability of obtaining a dwarf plant is?

Answers

Answer 1

When a tall plant (TT) in pea is crossed with another tall plant (TT), the probability of obtaining a dwarf plant is 0%.

Both parents are tall plant (TT) which are homozygous dominant for the trait of plant height. This means that they both have two copies of the allele that codes for tall plant height (T). Since the allele for tall plant height is dominant, it masks the presence of any allele for short plant height (t). In this cross, both parents only have the allele for tall plant height, so all of their offspring will also have the allele for tall plant height.

This can be represented in a Punnett square shown in the attached picture. As you can see in the Punnett square, all the offspring will be TT, and will be homozygous dominant for the trait of plant height and will exhibit the dominant trait (tall plant height).

Therefore, all the offspring will be tall and none of them will be dwarf.

Explanation:

It is known as lactation. The suckling action of an infant produces prolactin, which leads to milk production; more suckling leads to more prolactin, which in turn leads to more lactation. This is a positive feedback system as the product (milk) produces more suckling and more hormone. When the child is no longer breast feeding, the prolactin drops off and milk production goes down.

C. Describe the role of miRNA in gene expression.

Answers

Answer:

Explanation:

A. The role of promoter in eukariotic gene expression is It is to bind transcription factors that regulate transcription initiation. This molecule is so important because control the binding of RNA polymerase to DNA. The promoter region may be short or very long; the longer the promoter is, the more protein binding space is available. A negative regulatory molecule has the possibilty to inhibit transcription at the promoter because these molecule block the binding of RNA polymerase to the promoter region, thus not allowing the initiation of transcription, in some particular cases the negative regulator binds to the lac repressor and will bind to the promoter in the same site where RNA polymerase would bind to.

B. Two process that occurs during RNA processing are RNA splicing and 5′ capping, 3′. RNA splicing is a process known for removing the introns from the pre-RNA and stuck back together the restant parts, exons. This process has as a goal form a mature mRNA that does not contain the intron sequences. RNA splicing has an effect on the variation of mRNA molecules because through a process called alternative splicing more than one mRNA can be made from the same gene. 

C. Even though they are not quite the same thing miRNA and negative regulatory molecules have the same role, which inhibits the translation and silence genes. They regulate gene expression by binding to the 3'-UTR of their target mRNAs and destabilizing the mRNA and translational silencing, repressing protein production. Even so, under specific circumstances, miRNA can activate translation or regulate transcription.

A student prepares for a five-mile run so she eats a nutritious meal three hours before the run. Which correctly illustrates the transformation of energy from eating the meal to the five-mile run?

Answers

Answer: The transformation of energy from eating the meal to the five mile run is from

Chemical energy --> kinetic energy--> thermal energy.

Explanation:

In nature, energy exists in various forms. These forms are inter- convertible, that is, one form of energy can be transformed into another form. Such energy transformations are governed by the laws of thermodynamics.

The first law of thermodynamics states that energy cannot be created or destroyed but may be transformed from one form into another.

Living organisms which comprises the biotic components of an ecosystem are energy converters. For example:

--> plants convert solar energy into chemical energy during photosynthesis

--> animals convert chemical energy into kinetic energy when they move about. This in turn is lost as heat energy when highly complex organised food molecules are broken down.

From the question, the student ate a nutritious meal ( CHEMICAL energy) which is converted to KINETIC energy as she took a five miles run ( as she worked). 'Work' here refers not only to physical activities but also to the various metabolic processes necessary to maintain life. And each time work is done, kinetic energy is converted to heat( thermal energy)

How do the distances between the terrestrial plants compare to the distances between the gas giants?

Answers

Answer:

They are different from rocky or terrestrial planets that are made of mostly rock. Unlike rocky planets, gas giants do not have a well-defined surface – there is no clear boundary between where the atmosphere ends and the surface starts! The gas giants have atmospheres that are mostly hydrogen and helium.

Explanation:

I hope this helps!

They vary from planets that are predominantly made of rock, such as rocky or terrestrial planets. Unlike solid planets, gas giants lack a clearly defined surface, there is no discernible line separating the atmosphere from the surface.

What are terrestrial planets?

Telluric planets are another name for terrestrial planets. The Latin words terra and tellus, which both indicate Earth, are the source of the words terrestrial and telluric, respectively.

While the terrestrial planets were warmed by the sun's rays, the Jovian planets developed above the frost line.

Worlds that could float on water and worlds appropriate for manned missions were created under very distinct circumstances, but they have some striking similarities. Every world in our solar system is different.

Therefore, the atmospheres of the gas giants are primarily composed of hydrogen and helium.
