Answer: True.

Quizlet is a very good resource to use for problems like this.

Food we eat has not been modified through selective breeding. This statement is true.

What is selective breeding?

Selective breeding is the process where individual organisms with certain desirable traits are selectively bred for the purpose of propagating that particular trait.

Selective breeding is applied in agriculture for the purposes of rearing or cultivating high yielding breeds of farm animals and crops.The food we eat has been modified through selective breeding. Hence the statement: Food we eat has not been modified through selective breeding.

Milk production selective breeding has bee applied in milk production by selectively rearing cows with high milk production as planting of disease-resistant crops selective breeding has been applied in the cultivation of disease resistant crops.

Therefore, Food we eat has not been modified through selective breeding. This statement is true.

Based on the information above, which of the following is true about the process in which the genetic code stored in DNA is used to
produce protein products?
A. This process occurs only in embryonic cells directly after fertilization,
This process only occurs in animal cells because it requires the presence of ribosomes.
This process does not require an input of energy because it is semi-conservative,
D.This process requires the interaction of several different cellular structures,

Answers

Answer:

D.This process requires the interaction of several different cellular structures,

Explanation:

We don't have the information above. However, this process occurs in all cells, and it requires energy. Semi-conservative refers to the fact that, during DNA replication, each new molecule of DNA is made up of one strand of the original DNA molecule and one strand of a new molecule.

The synthesis of proteins from the information in an mRNA molecule does require several structures in the cell, including the nucleus, ribosomes, endoplasmic reticulum and Golgi apparatus.

Which particle, protons, neutrons, or electrons, has the LEAST mass?

Answers

Answer:

Electrons are much smaller in mass

Explanation:

Although similar in mass, protons are positively charged, while neutrons have no charge. Therefore, the number of neutrons in an atom contributes significantly to its mass, but not to its charge. Electrons are much smaller in mass than protons, weighing only 9.11 × 10−28 grams, or about 1/1800 of an atomic mass unit.

What is the complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT?
A. TAC CCG GTA
B. UAC CCG GUA
C. ATG GGC CAT
D. CGA AAT AGC

Answers

The answer to this is A. The complementary strands are A-T, T-A, G-C, C-G, and U-A

The complementary strand of DNA that is made during DNA replication if the template/parent strand of DNA reads ATG GGC CAT is TAC CCG GTA. Thus, the correct option for this question is A.

What is DNA replication?

DNA replication may be defined as a type of biological process through which two identical replicas of DNA form from one original DNA molecule. This process makes a copy of the DNA in a cell is made before the cell divides.

When it comes to the complementary strand of DNA, either of the two chains makes up a double helix of DNA, with corresponding positions on the two chains being composed of a pair of complementary bases.

For example, if Adenine A is present in the parental DNA, then it should be complementarily bounded to the thymine and vice versa. Similarly, if Cytosine is present in the parental strand of DNA, then it should be complementarily bounded by guanine and vice versa.

Therefore, the correct option for this question is A.

A. A biodiverse ecosystem is not affected in any way by disturbance.
B. A biodiverse ecosystem harbors many interactions, thus a

C. The relationship between the biodiversity of an ecosystem and its
ability to rebound from disturbance is unknown.
D. A biodiverse ecosystem has so many interactions that the
slightest disturbance will destroy it.

Answers

Answer:

B. A biodiverse ecosystem harbors many interactions, thus a  disturbance may impair some interactions, but not all.

Explanation:

Biodiversity is the variation of life forms in an environment. This is as a result of available nutrient and energy to support the various life forms.

The relationship between biodiversity and rebound from disturbance is such that a biodiverse ecosystem is able to resist any change. The disturbance might affect proportion of the populace. But on the long organisms can survived and be propagated again.

When a food handler can effectively remove soil from equipment using normal methods, the equipment is considered what?

Answers

Answer:

Cleanable

Explanation:

Cleanability refers to the ease with which microorganisms or particles can be removed from the equipment used in food production. To be cleanable the roughness of the machine being employed in production is not expected to exceed 0.8μm.

The Atomic Force Microscope is used to measure the surface roughness of machines. Cleanability is important as it ensures that the machines used in food production are safe.

When a food handler can effectively remove soil from an equipment by using normal methods, the equipment is considered to be; Corrosion Resistant.

The soil referred to her would be dirt because we are talking about a food handler.

Now, if the food handler is finding it difficult to remove dirt from the equipment by using normal/regular methods, it means that the soil/dirt has succeeded in having some kind of chemical reaction with that equipment.

If that is the case, then it means the equipment is undergoing corrosion because corrosion is defined as the gradual destruction of a metal by chemical reaction with the environment.

Since we have established that inability to use normal method denotes corrosion, then if he can use normal methods to remove the soil effectively, then the equipment is said to be corrosion resistant.

Which of the following is an example of an ecosystem service that would provide protection from a hurricane storm surge?

A lock and dam system

An intact coastal wetland

An energy-producing tidal barrage system

An offshore, deep-water fish farm

Answers

Answer: An intact coastal wetland

Explanation:

Hurricane storm surges results when the water level rises above normal as a result of a storm and therefore goes inland from the coast far deeper than it normally does.

Normally this can destroy things next to the coast by washing them away but some ecosystem services can provide protection against this such as an intact coastal wetland. Being intact, there are less chances of being washed away and as it is a wetland it is used to high levels of water and can even absorb some of the surge.

In camellia plants, flower color is controlled by a single gene with codominant alleles. A camellia plants with red flowers (RR) is crossed with a camellia plant with white flowers (WW). What are the expected phenotypes of the offspring of this cross?
A.
All will have red flowers.
B.
Half will have red flowers and half will have white flowers.
C.
All will have both red and white flowers.
D.
All will have pink flowers.

Answers

Answer:

The answer is; c

It is important to distinguish between codominance and incomplete dominance.

In incomplete dominance, the two alleles blend with each other in phenotype  giving offspring with intermediate phenotypes, hence offspring would produce pink flowers, in this case.

In codominance, both alleles are simultaneously expressed in phenotype in the offspring. Therefore flowers, in this case, would exhibit both red and white colors.

Is the coloring of the peppered moths an example of competition, differential reproductive success, or inherited variation? Explain why.

Answers

Answer:

Peppered moths get their color in lieu to become the fittest among all so that they can survive easily.

Answer/Explanation:

Differential reproductive success.

When the Birch(white) trees were covered in soot(making them black). The black pepper months could blend in to the tree while the white moths stood out.

When the Birch(white) trees were clean and white. The white pepper moths could blend in to the tree while the black moths stood out.

This is an example of differential reproductive success. Who ever could blend in with the tree had the better genes because it made them difficult to be spotted. The other type of moth would be not so lucky, easily spotted an eaten. The better gene lead is "successful," because that moth could live longer because of its characteristics..
