In sweet pea plants, purple flower color is dominant over red flower color and long pollen grain shape is dominant over round pollen grain shape. Two sweet pea plants that we heterozygous for both flower color and pollen grain shape are crossed with one another. A geneticistis surprised to observe that there are fewer round purple offspring and long red offspring than were predicted by the 9:3:3:1 expected phenotypie ratio Which of the following statements provides the most reasonable prediction to account for the deviation from the expected results?
A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked
B) In sweet pea plants the genes for flower color and for pollen grain shape both exhibit codominance
C) Several mutations occurred spontaneously producing a deviation from the expected phenotypic ratio of the offspring
D) The genes for flower color and pollen grain shape are inherited independently because of the law of independent assortment

Answers

Answer:

The correct answer is - option A) in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked.

Explanation:

In this given case the result of phenotypes are not as expected and does not follow the law of independent assortment presented by Mendel. It appears to be the case of genetic linkage as it is not following the mendelian law by producing fewer round purple offspring and long red offspring which do not satisfy the expected mendelian ratio of 9:3:3:1. Mutation can lead to failure in producing proteins but could not affect the phenotypic ratio of the plant.

Thus, the correct answer is - option A.

Medel was the Father of Genetics, who gave the laws on independent assortment, dominance, and segregation of the genes.

However, there are some exception that violates these laws, such as genetic linkage is one of the exceptions that violates the law of independent assortment.

The correct answer is:

Option A. in sweet pea plants, the gene for flower color and the gene for pollen grain shape are genetically linked

In the given data, the results can be interpreted as:

The Law of independent assortment states that the two or more alleles of different genes are assorted independently.

In the given example, the genetic linkage occurs, which does not follow the ratio of 9:3:3:1. The genetic linkage does not follow the law of independent assortment, which results in fewer purple offspring.

Thus, mutation can cause the failure of Mendel laws and can affect the phenotypic traits of an organism.

Therefore, Option A is correct.

Explicitly explain how a living organism obtains energy after eating.​

Answers

Answer:

Explanation:

Tiny bits of the food you ate break down into a simple sugar called glucose. In your cells, energy from the sugar is released when oxygen and glucose combine in a reaction. The reaction produces water, carbon dioxide, and energy in the form of ATP. This chemical process is happening all the time in your cells.

Describe the nervous response pathway when you taste something bad and spit it out. Using these keywords: stimulus, chemical receptor, sensory neurone, relay neurone, motor neurone, muscles, response, electrical impulse, chemicals

Answers

Answer: Nervous system includes the brain which is the main center for interpreting various stimuli in the environment.

Explanation:

The nervous system detects the food stimulus. The chemical receptors present in the tongue detects the chemicals present in the food. These receptors send the impulses to the sensory neuron present in the brain.  The impulse is then transmitted to the relay neuron then to motor neuron and then finally to the muscles of the mouth. The muscles of the mouth help in spitting the food as the sensory neurons help in detecting the taste of the food and find it either edible or non-edible.

Which of the following is the best description for the glucose transporter?

a. It's a carrier protein doing facillitated diffusion
b. It's a carrier protein doing active transport
c. It's a protein channel doing facillitated diffusion
d. It's a protein channel doing active transport

Answers

Answer:

a. It's a carrier protein doing facillitated diffusion

Explanation:

Facilitated diffusion may be defined as the transportation of molecules from a high concentration to a low concentration that is down the concentration gradient without input of the energy. Whereas the active transport is transportation of the molecules from the low concentration to the high concentration which is against concentration gradient by the membrane protein.

The glucose transportation process requires membrane protein for the transport and does not require any energy. Therefore, it is carrier protein which is doing the facilitated diffusion.

The trait for tall pea plants is (T) and the trait for short pea plants is (t). The trait for smooth pea plants is (R) and the trait for wrinkled is (r).Two plants are crossed producing a F1 generation of plants with 612 tall and smooth pea plants and 188 short and wrinkled pea plants.What would be the most likely genotype of the parental generation?

Answers

Answer:

P generation = TtRr × TtRr i.e both parents were heterozygote for both traits

Explanation:

This question involves two genes encoding the height and texture in pea plants respectively. The alleles for tall and smooth pea traits are dominant over the alelles for short and wrinkled traits.

According to this question, two plants are crossed to produce F1 offsprings as follows: 612 tall and smooth pea plants and 188 short and wrinkled pea plants.

First, we turn this derived number of offsprings into ratio by dividing by the smallest number (188)

612/188 : 188/188

3.25 : 1

Approximately; we can say this is 3 (tall and smooth) : 1 (short and wrinkled)

Based on this ratio, which was got by Mendel for his F1 offsprings when he crossed pea plants, the parental generation has a heterozygous genotype (TtRr).

How have human activities effected the air in earth’s atmosphere?

Answers

Answer:

Human activities have had a negative impact on Earth's atmosphere.

Explanation:

Human activities, since the Industrial Revolution, have gradually been having more and more influence on Earth's atmosphere. As more and more the economies have developed, the bigger and bigger the output of gases into the atmosphere. The gases that are released into the atmosphere are mostly greenhouse gases, but there are also some that are highly toxic.

This has contributed to a sharp increase in CO2 levels in the atmosphere, which is speeding up the process of global warming, and that can have devastating consequences for life on Earth. Also, some of these gases managed to cause huge damage to the ozone layer, the layer that protects us from UV radiation, and if the ozone is gone, every complex organism will be gone as well.

In the fourth century BC, Aristotle observed a phenomenon in which he saw a circular shadow on the Moon. He argued that Earth was a sphere based on this observation. What phenomenon caused the shadow on the Moon? *


a solar eclipse

a lunar eclipse

a spring equinox

a summer solstice

Answers

Answer:

a lunar eclipse

Explanation:

The shadow that Aristotle saw was caused by a lunar eclipse. At that time the sun, earth, and the moon nearly straight alignment caused the Earth's shadow to be reflected on the moon. This shadow is what ultimately led Aristotle to believe that the Earth was a sphere. This should not be confused with a solar eclipse which is similar but instead the sun, moon, and earth align in that order which causes the moon to completely block the sun to anyone on earth.
