Answers

Answer 1

Answer:

Revolving nosepiece

Explanation:

The revolving nosepiece (also called the turret) is the part of the microscope we can turn in order to view an object through different objective lenses. Objective lenses, which provide different levels of magnification (usually 4x, 10x, 40x, and 100x), are all attached to the revolving nosepiece. It allows us to switch lenses from those that provide less magnification to those that provide more. This is how we can see more details on an object we're observing.

You can see what this part of the microscope looks like in the image attached below:

An early step in the process of carbon fixation combines three molecules of CO2 with three molecules of RuBP to produce three 6-carbon molecules, which are immediately converted to six 3-carbon molecules. These six molecules are phosphorylated and reduced to produce glyceraldehyde 3-phosphate (G3P). What additional events occur to complete the Calvin cycle

Answers

Answer:

release of one G3P to make sugars and regeneration of RuBP

Explanation:

The Calvin cycle can be defined as a part of photosynthesis that utilizes the energy stored by light-dependent reactions to produce three-carbon sugars. The first carbohydrate produced by the Calvin cycle is a three-carbon sugar phosphate called glyceraldehyde-3-phosphate (G3P). Subsequently, G3P is used to produce other sugar molecules such as, for example, glucose. The Calvin cycle consists of three steps: 1-carboxylation (by using CO2 in a reaction catalyzed by Rubisco enzyme), 2-reduction of phosphoglycerate (ATP phosphorylation), and 3-regeneration of ribulose-bis-phosphate (RuBP) by using triose phosphates produced in the first two steps.

Do you agree that wild species such as orangutans have the right to exist whether or not they are useful to humans? Explain.

Answers

Answer:

Because orangutans live in only a few places, and because they are so dependent upon trees, they are particularly susceptible to logging in these areas. Unfortunately, deforestation and other human activities, such as hunting, have placed the orangutan in danger of extinction.

Explanation:

Hope this helps ;)

Ape like organisms with red coloured hairs that are mammals and belong to the Hominidae family are called Orangutans. They are found in the rainforests and are 1.2 - 1.8 m in height.

To this open question, I don't agree with the statement.

The viewpoint can be explained as:

They have the right to exist even when they are not useful to humans as they play a vital role in the food chain and the ecosystem in which they reside.

If Orangutans are withdrawn from the ecosystem then many plant species will be impacted or can vanish.

Orangutan helps in seed dispersion and sustain a healthy and balanced condition of the ecosystem.

The residents, trees and the ecosystem are interdependent for survival and hence, they cannot be removed.

Answers

Answer: The FDA and USDA cerate food safety programs, safeguards to protect Americans, to protect people from unsafe food. The FDA has monitoring programs for pathogens, naturaltoxins, pesticides, etc.; their methods are science-based.

The safeguards that are placed to protect Americans from unsafe food are FDA and USDA. FDA means food and drug administrator and USDA means U.S. department of agriculture.

What are FDA and USDA?

FDA stands for food and drug administrator. It is a health and food department to ensure public health and to check the food items that the citizens are consuming.

USDA stands for The United States Department of Agriculture. The department is responsible for making the laws regarding food quality, and they also develop new qualities of fruits and vegetables.

These departments are based on scientific research and methods. Many scientists work under this to save people from having bad food.

Answers

Answer:

a.) 12 Newtons

b.) Same Direction

c.) Unbalanced

Explanation:

The system shows 2 individual forces:

A force of 5 N pulling the box LEFT

A force of 7N pushing the box LEFT

Both forces are LEFT, so they have the same direction.

Since the parallel forces both have the same direction, regardless of whether it's a push or pull or what side of the box the force acts upon, the resultant force will be the sum of the two forces in their direction:

Resultant force's magnitude is then: 5N + 7N = 12N

Resultant force's direction: unchanged = LEFT

Since the resultant force's magnitude is not 0, the system is unbalanced.

What would be the expected genotypic and phenotypic segregation ratios if you self-fertilize a RrYy individual

Answers

Answer:

Explanation:

From the information given:

The analysis of the hypothetical pathway gives:

                         Y gene                                  R gene

Green fruit            →         Yellow fruit               →           Red fruit.

If RrYy undergoes self-fertilization, the expected genotypic and phenotypic segregation is:

RrYy × RrYy

The progenitors to undergo the segregation are as follows:

                 RY            Ry            rY                 ry

RY             RRYY      RRYy         RrYY            RrYy

                (red)           (red)        (red)            (red)

Ry             RRYy        RRyy         RrYy           Rryy

                (red)         (green)       (red)           (green)

rY             RrYY           RrYy         rrYY            rrYy

               (red)             (red)        (yellow)      (yellow)

ry              RrYy         Rryy            rrYy             rryy

                (red)          (green)        (yellow)      (green)

Thus; the expected phenotypic ratio is:

= 9(red)  : 3(yellow) : 4(green)

The expected phenotypic ratio is:

= 1(RRYY): 2(RRYy): 2(RrYY): 4(RrYy): 1(RRyy): 2(Rryy): 1(rrYY): 2(rrYy): 1(rryy)

A Vaccine ordinarily contains a specialist that takes after a sickness causing microorganism and is frequently produced using debilitated or executed types of the organism, its poisons, or one of its surface proteins. The specialist invigorates the body's safe framework to perceive the specialist as a danger, pulverize it, and to additionally perceive and decimate any of the microorganisms related with that specialist that it might experience later on.

Vaccines can be prophylactic (to forestall or enhance the impacts of a future contamination by a characteristic or "wild" microorganism), or therapeutic (to battle a sickness that has just happened, for example, cancer).

B.N-H bond
C.C-C bond
D.C-N bond

Answer:

The correct answer is - D.C-N bond

Explanation:

A chemical bond is formed between the carboxyl group of an amino acid to the amino group of the other amino acid and release a water molecule. It is a dehydration synthesis reaction.

So, the peptide bond normally formed by the reaction between amino acid from C1 of one amino acid molecule and N2 of the other amino acid molecule.

So the peptide bond that formed by this reaction is involve bonding of C-N bond.
