All the DNA from a desired organism is isolated to form recombinant DNA for use in a host. C. Different sections of DNA from a desired organism are inserted into a host so that beneficial traits will be expressed. D. One strand of DNA is isolated and inserted into a host so recombinant DNA can be formed.

Answers

Answer 1

Answer:

A. Fragments of DNA that have desired genes are isolated to form recombinant DNA for use in a host.

Explanation:

Genetic engineering, also known as genetic modification, is a technique that involves the manipulation of an organism's genome using biotechnology procedures. The purpose of genetic engineering is to create an organism with desirable traits.

Genetic engineering involves series of steps, however, the very first step is that of DNA EXTRACTION. The fragments of DNA that have desired genes are isolated from the involved organism. The extracted DNA called the recombinant DNA, which is inserted into the host genome.

List and define the four main elements of the water cycle.
(SCIENCE)

Answers

Answer:

There are four main stages in the water cycle. They are evaporation, condensation, precipitation and collection

Explanation:

Evaporation- Is the the process in which water changes from a liquid to a gas or vapor.

Condensation- Is the process in which water vapor or gas in the air is changed into a liquid. Is the opposite of evaporation.

Precipitation- Precipitation is water from clouds in the form of rain, freezing rain, sleet, snow, or hail.

Collection- This is when water that falls from the clouds as rain, snow, hail or sleet, collects in the oceans, rivers, lakes, streams. Also some will soak into the ground and will collect as ground water.

Explanation:

What are the uses of fluoride ?  

Fluoride is a group of compounds which is a combination of fluorine and other elements, these compounds are present in water, plants, rocks, air, and soil.

Some of fluoride compounds are sodium fluoride, stannous fluoride, and fluoride mono-fluorophosphate.

Once fluorides are absorbed inside the body, it travels into the blood through the digestive tract, tend to collect in areas with high calcium like  bones and teeth.

Majorly fluorides are used in drinking water, beverages, food, and  dental products, mostly fluoro-silicic acid, sodium fluorosilicate, and sodium fluoride forms are added to water.

Some of the fluoridated water used to prevent tooth decay, and  avoid  dental fluorosis, a cosmetic condition.

Average number of decayed, missing, or filled teeth in children reduced by application of this water and  cavities in adults.

Why are invasive species dangerous to the environment?
A)They pollute the environment.
B)They are always predators.
C)They threaten biodiversity.
D)They bring abiotic factors.

Answers

Answer:

C

Explanation:

They threaten the other animals. They can take their food, homes, and they don't have natural predators.

Invasive species are dangerous to the environment as they threaten the biodiversity. Thus, the correct option is C.

Invasive species are those imported species that are able to thrive rapidly in another foreign area by adapting and reproducing quickly.

Invasive species of plants and animals lead to an increase in the competition for survival, which results in decrease in the population of the native species.

The invasive species also affect the food web that is existing in the particular ecosystem, because of which other all organisms which are part of the food web are affected. They outcompete the native species for food,

Thus, biodiversity is threatened due to the invasive species.

In Chapter 6, you were introduced to the polymers of life and their building block structures, as shown below in Figure 11.1. Recall that the monomer units for building the nucleic acids, DNA and RNA, are the nucleotide bases, whereas the monomers for proteins are amino acids, for carbohydrates are sugar residues, and for lipids are fatty acids or acetyl groups.

Explanation:

For her science fair project, your little sister replicated one of Mendel's experiments. From a P0 pea plant with purple flowers and a pea plant with white flowers, she got 1 purple F1 hybrid (she had forgotten to water, so just one survived). From this self-fertilized F1 she got 8 F2 offspring. 7 were purple and 1 was white, for a 7:1 ratio. Did your little sister just disprove Mendel's laws

Answers

Answer: No, the 7:1 ratio is close to the expected 6:2 ratio even with the limited sample size.

Explanation:

Let the alleles be P (purple) and W (white).

The possible crosses are

PP x WW, PP x PW, PW x WW, PW x PW

the F1 is PP or PW

one F2 is white so the F1 must be PW and

the F2 are PP, WW, PW and

the expected 8 progeny are 2PP, 2WW, 4PW

Because 7/8 are purple, we can infer that P is dominant and W recessive, so the expectation is 6 purple, 2 white

The observed ratio is similar to the expected ratio, so we can’t say that this result disproves Mendel, particularly with a small sample.

7:1 is close to 6:2, even if the sample is smaller. We cannot invalidate Mendel with such a small sample size because the observed ratio was not statistically different from the anticipated ratio.

What is Mendelian Ratio?

The term "Mendelian inheritance" refers to specific patterns that can be observed in the way characteristics are passed down from parents to children. In the 19th century, the Austrian monk Gregor Mendel conducted thousands of tests with pea plants in order to develop these broad patterns. He did this in order to determine the genetic makeup of pea plants.

The frequency with which diverse phenotypes are produced as a result of any cross incorporating Mendelian traits. in particular, the three to one ratio that is displayed by the second generation of descendants from parents who are different from one another in regard to a single character.

Morphological distinction is one of the steps necessary for speciation to occur.
What are the other two?

Answers

Answer:

Genetic Separation / Geographic isolation

Explanation:

Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.

The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.

Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

A.Plastic, because it takes more energy to raise its temperature B.Iron, because it takes more energy to raise its temperature C.Plastic, because it takes less energy to raise its temperature D.Iron, because it less energy to raise its temperature

Answers

Answer:

A

Explanation:

The correct answer would be plastic because it takes more energy to raise its temperature.

The specific heat capacity of a substance is the amount of heat required to raise the temperature of the substance by one degree. The more the specific heat capacity of a substance, the more the heat required to raise its temperature.

The specific heat capacity of plastics is generally more than that of metals. Hence, metals will get heated faster than plastics under the same condition. More energy would be needed to raise the temperature of plastics when compared to metals.
