Which of the following relationships is incorrect

Answers

Cholorplasts- site of lipid synthesis

Chloroplast is not a site of lipid synthesis, it is the site of performing photosynthesis Therefore, option A is correct.

What are chloroplasts and their functions?

An organelle found in the cells of plants and some algae called a chloroplast is where photosynthesis, the process by which solar energy is transformed into chemical energy for growth, takes place.

All green tissues in plants and algae contain chloroplasts in their cells. In photosynthetic tissues that don't appear green, such as the brown blades of gigantic kelp or the red leaves of some plants, chloroplasts are also present.

Thus, the cell wall provides support and protection to the cell, rough ER is the site of protein synthesis, the nucleus holds genetic material, and the chloroplast is the site of photosynthesis. Therefore, option A is correct.

Primer design is a critical step for the detection of a particular sequence in a sample. Which of the following would be true of primer design?

Answers

The group of choices is as follow:

A. RNA polymerase are added to the PCR mix to design random primers  

B. If detecting viral infection by PCR, the primers must not be complimentary (match) to regions of human DNA  

C. Pairs of primers must be designed, one to start amplification with Taq polymerase, the other to start amplification with human polymerase  

D. Primers are optional if you want to amplify all DNA within a sample

Answer:

The correct answer is - B. If detecting viral infection by PCR, the primers must be complementary to regions of human DNA.

Explanation:

Short, single-stranded segments of DNA sequences utilize in the real-time PCR or polymerase chain reaction technique are called primers. Primers used to hybridize the region of the segment needed to be amplified.

The human polymerase enzyme is not used in the PCR reaction and requires a 3'OH group to synthesize the DNA by amplification which is possible only in the presence of primers as they have a 3'OH.

Explanation:

Dependent on the level of comparison four types of homology are defined: ( 1) Iterative ( = serial = homonomy), (2) ontogenetic, (3) di- or polymor- phic, and (4) supraspecific homology. ... Scientists have recently been paying renewed attention to the homology question.

Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.

oxygen and nitrogen molecule consists of two oxygen atoms bonded to each other and same nitrogen atoms are bonded of each other.

Water molecules have one oxygen atom in the center and two hydrogen atoms, one on each side.

what are the properties of water molecule ?

It has no taste, odor, or transparency, where the nucleus of the oxygen atom  attracts electrons strongly than the nuclei of the hydrogen atoms.

In water molecule oxygen is more electro negative and electron-greedy than hydrogen, results in the development of  a partial negative charge on the oxygen of the water and a partial positive charge on the hydrogen end.

Water shows strong cohesive property where the attraction of molecules for other molecules of the same kind is referred to as cohesion.

Surface tension is defined as  the tendency of  the surface to resist rupture when they are subjected to stress due to cohesive forces.

If, somehow, the number of daylight hours did not change throughout the year, but Earth
was still tilted at 23.5°, would there still be seasons in the Northern and Southern
Hemispheres of Earth? Would the temperature difference between the seasons still be as
great? Explain your reasoning.

Answers

Answer:

There would still be seasons, because the intensity of light would still change throughout the year, due to the earth's tilt.

Explanation:

If, somehow, the number of daylight hours did not change throughout the year, but Earth  was still tilted at 23.5° then-

Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as great

The tilt of the Earth's axis at 23.5° leads to the different parts of the Earth to gets a high or less amount of direct sunlight at different times of the year.

If there would be no tilt of the earth then there would be no seasons on Earth.If the number of daylight hours did not change then seasons still be there due to the intensity of light would still change throughout the year as the earth is still tilted. If the number of daylight hours did not change throughout the year then the temperature difference would not be as great due to less light in the daytime will not be able to heat enough and the Earth would not be heated for a longer time in summer.

Thus, the correct answer is -

Yes, there would still be seasonsNo, the temperature difference between the seasons would not be as great.

Which population is most likely to have exponential growth?

cleaned
B. The angelfish living in a coral reef where there are many sharks
C. The mice living in a meadow with plenty of predators and limited
food
D. The foxes living in a forest where they compete with other animals
for food

Answers

Answer:

A. The dust mites living in a sofa that is often used and never cleaned

Explanation:

Without the sofa being cleaned, the dust mites will never experience any predation or die off from humans and harsh cleaning chemicals. This will enable the population to increase exponentially, as opposed to the other options where the organisms are at risk for ample predation and starvation.

Exponential growth refers to the growth of organisms in an environment having unlimited resources. The organism grows exponentially or in a geometric fashion.

The dust mites living on the sofa that is often used and never cleaned.

The population has high chances of exponential growth will be:

1. Exponential growth is seen in the environment or surroundings where the resources are plentiful, and the number of organisms is dependent on those resources.

2. The dust mites living in the sofa that has never been cleaned will show exponential growth. Since the sofa is never cleaned, the mites have never faced any elimination by chemicals. The population will increase exponentially.

3. The other options have chances of competition, starvation, and predation that will not lead to the exponential growth of organisms.

Thus, the correct answer is Option A.

Explanation:

An experiment was conducted to demonstrate the passage of glucose and starch across a selectively permeable membrane that allows monomers but not polymers to diffuse through.

Glucose and starch powders were mixed in 10 ml of water and poured into a cellulose bag, which was then sealed at both ends and placed in a beaker of water. After 30 minutes, the presence of glucose in the beaker was recorded with a testing paper, which turns green if glucose is present. The presence of starch was recorded by adding a few drops of iodine, which causes the solution to turn violet if starch is present.

A beaker filled with 100 milliliters of distilled water. A bag filled with 10 milliliters of water and a solution of 2 percent glucose and 2 percent starch is placed in the beaker of water.

Which statement best describes the expected result?

A) The testing paper will turn green and the solution will turn violet.
B) The testing paper will turn green and the solution will not turn violet.
C) The testing paper will not turn green and the solution will turn violet.
D) The testing paper will not turn green and the solution will not turn violet.
