It corresponds to the formula of an acid oxide and a basic oxide:

Select one:

A. P2O3 y BaO
B. Mag y N2O5
C. FeO Y SO3
D. HNO y CaO

Answers

Answer 1

Answer:

P2O3 y BaO

Explanation:

The oxides of the main group metals are basic in nature. They form alkaline solutions when dissolved in water. Similarly, the oxides of main group non metals form acidic solutions when dissolved in water.

P2O5 is an oxide of a main group nonmetallic element in group 15. We expect this oxide to be acidic and form acids when dissolved in water as expected from the chemistry of the group.

Also, BaO is an oxide of barium, a group two main group metal. Hence we expect this oxide to be basic in nature and form alkaline solutions.

Which term refers to all areas of Earth where life exists?
biosphere
biome
community
ecosystem

Answers

Biosphere! Your welcome:)

The term that used to represent the land, water, surface and atmosphere of the whole planet where life exists is called the biosphere. So option A is correct.

What is the biosphere?

Multiple species make a population, population makes a community, the community makes an ecosystem, ecosystem makes a biome, and biome makes a biosphere.

The biospheres can be classified as:

Lithosphere: It consists of the land part of the earth. The lithosphere comprises plains, plateaus, mountains, etc.

Hydrosphere: The water constituent of the earth forms the hydrosphere. It includes rivers, oceans, lakes, ponds, etc.

Atmosphere: The air surrounding the earth comprising of varying gases forms the atmosphere of the earth.

So biosphere is the largest unit of ecology which include the whole planet like earth in it. So option A is correct.

pros and cons of genetically modifying the animals people eat? ​

Answers

Answer:

Explanation:

   GMOs are food items that have been made using genetic engineering techniques. ...

   GMO foods are easier and less costly for farmers to grow, which makes them cheaper for the consumer. ...

   The main concerns around GMOs involve allergies, cancer, and environmental issues — all of which may affect the consumer.

The advantages include improved human health, increased food production, reduced environmental impact, and so on. There is a risk that new diseases originating in genetically engineered animals will be transmitted to non-genetically engineered animals, including humans.

What is genetic engineering?

Genetic engineering (also known as genetic modification) is a process that uses laboratory-based technologies to alter an organism's DNA makeup.

This could be as simple as changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a new segment of DNA.

Gene therapy aims to modify genes in order to correct genetic flaws and thus prevent or cure genetic diseases. The goal of genetic engineering is to modify the genes in order to improve the organism's capabilities beyond what is normal.

The benefits include improved human health, increased food production, and reduced environmental impact, among other things. There's a chance that new diseases originating in genetically engineered animals will spread to non-genetically engineered animals, including humans.

Thus, these are some pros and cons of the genetically modified animals.

Blonde hair (represented as b) is a recessive trait. If Julie has blonde hair, which of the following could have been her parents' genotypes?
A. Bb, bb
B. BB, bb
C. BB,BB
D. Bb,BB

Answers

I think its Bb, bb because if julie has blonde hair then it's most likely to be Bb, bb

If Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.

What do you mean by Genotypes?

Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for specific studies in order to express some genetic characteristics.

According to the context of this question, if the trait of Blonde hair is recessive in nature. This means that both the alleles of this gene are recessive, i.e. bb.

Now, if Julie has blonde hair, which means both alleles are recessive. So, the genotypes of parents of Julie are either homozygous recessive or heterozygous in nature. This characteristic is well determined by option 1.

Therefore, if Julie has blonde hair, the genotypes of their parents could have been found to be Bb and bb. Thus, the correct option for this question is A.

What process is similar in function to genetic engineering but different in the mechanism it uses? A. Replication in a bioreactor B. Cellular Respiration C. Breeding for specific traits D. Genetic Calculus

Answers

Option C. Breeding for specific traits is a similar process in function to genetic engineering but different in the mechanism it uses.

Genetic engineering refers to the process of using recombinant DNA methodologies to alter the genome of a particular organism and thus obtain the desired characteristics/traits in organisms derived from them.

An example of genetic engineering is the use of recombinant DNA methodologies to develop Escherichia coli strains that generate human insulin.

Moreover, selective breeding refers to the process aimed at developing organisms with desirable characteristics by choosing parents with these traits in order to cross them and produce offspring with these phenotypic traits.

For example, wheat plants with better yields can be obtained by crossing between wheat varieties that exhibit desired phenotypic traits.

In conclusion, Option C. Breeding for specific traits has a similar objective that genetic engineering but the mechanism to reach this objective is different.

1.What is meant by Plasma therapy ? Is it a remedial treatment for Coronavirus? Express your answer with valid points

Answers

Answer:

It is a therapy that involves the use of plasma from recovered patients (which is composed of antibodies against the virus)

Explanation:

The immune system of patients already recovered from viral diseases naturally generates defensive molecules that circulate in the blood. These molecules are known as 'antibodies', and they are localized in the plasma of the blood, which is composed of coagulation factors, albumin, fibrinogen and, of course, antibodies. These antibodies bind to specific viral antigens in order to promote their neutralization and destruction. In consequence, the plasma from recovered patients contains particular antibodies that may be used to treat specific diseases.

Answer:

Suppose you take glycine tRNA and modify it so that the glycine is changed to valine. You then find that the amino acid sequence in the generated proteins does not show the expected change.

A garden has a length of 1.5 x102 m and a width of 0.5 x 102 m. what is the area of the garden?

Answers

Answer:

7.5 × 10^3 m^2

Explanation:

The garden described in this question takes the shape of a rectangle, which has a length of 1.5 x102 m and width/breadth of 0.5 x 102 m.

To calculate the area, we use the formula for calculating the area of a rectangle, which is;

Area = length (L) × width (w)

Area = 1.5 x102 m × 0.5 x 102 m

Area = 150 × 50

Area = 7500

This, the area of the garden is 7500m^2 or 7.5 × 10^3 m^2

Answers

Answer:

The correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia

Explanation:

Protists use different type of structures for their movement known as pseudopods, flagella, and cillia.

Pseudopods are the structures found in amoeba in which flowing of protoplasm moves the amoeba forward.

A euglena moves by strikes or whip its flagellum, that is a long appendages, like propeller of a helicopter.

Cilia are thin, very small tail-like structure that stretched outward from the of body of paramecium.

Thus, the correct answer is -  amoeba: pseudopod; euglena: flagellum; paramecium: cilia
