Explanation:

1. DNA double helix

2. adenine and thymine cytosine and guanine

3. To contain genetic materials

Explanation:

Hey there!

Your answer is option B.

Reason:

Base are the substance that produces hydroxyl ion dissolving in water.

Option A(true): The pH value of base is always greater than 7.

Option B (false): A base is considered as alkaline if it dissolves in water only otherwise they are not alkaline.

Option C (true): A base always has few hydrogen ions in it.

Option D(true) : A base has also few hydroxide ions.

Answer:

D. 300 m²

Explanation:

A sphere is a three dimensional object with a surface which as like that of a ball. A sphere is a set of points that are all at the same distance r from a given point in a three-dimensional space.

The surface area of a sphere is:

Surface area = 4πr²

where r is the radius of the sphere, π is a constant = 3

Given that r = 5 meters, hence substituting into the area equation:

Surface area = 4π(5)² = 4(3)(5)² = 300 m²

Answer: The main properties of water are its polarity, cohesion, adhesion, surface tension, high specific heat, and evaporative cooling.

Water has the unique ability to dissolve many polar and ionic substances. This is important to all living things because, as water travels through the water cycle, it takes many valuable nutrients along with it! Water has high heat capacity.

Answer:

Carbon dioxide, excess water produced during respiration and nitrogenous compounds produced during protein metabolism are the major excretory products in plants. Plants produce two gaseous waste products i.e. oxygen during photosynthesis and carbon dioxide during respiration.

Hello. You did not enter the text to which this question refers, which makes it impossible for it to be answered. However, I will try and help as best I can.

The only way you can answer this question is by reading the text. During this reading, you will notice that there is an element in monoculture that is harming bees, making them have a very difficult life or even die. This element is what is affecting the bees. The author will show why this element is harmful to bees through sentences that prove the effect that this element promotes and how it only exists in monocultures. These sentences will be the text evidence.

It is likely that the author shows how monoculture requires a large use of pesticides, which ends up harming the life of bees. He can also show that monoculture decreases the availability of food for bees, since all monoculture plants only flower once a year and leave the bees without food for the rest of the year, as there is no plant diversity in the monoculture.

Answer:

sample response

Explanation:

Because of the growth of the almond trees, many honeybees have died. Honeybees do not naturally live near the trees so they are transported to the area in order to pollinate the trees. However, the bees are exposed to pesticides that are used on the trees. Many also likely die because the almond trees only bloom in February, so the bees do not have enough food for the rest of the year.

"The real answer is It is a barrier with tiny openings that let some, but not all, materials pass through"

Answer:

Semipermeable membrane is a type of biological or synthetic, polymeric membrane that will allow certain molecules or ions to pass through it by diffusion—or occasionally by more specialized processes of facilitated diffusion, passive transport or active transport.

Explanation:

The real answer is It is a barrier with tiny openings that let some, but not all, materials pass through.

When plant cells are placed in salt solution their appearance is different to when they are placed in distilled water. ... Therefore, water moves out of the cell across the partially permeable membrane by osmosis and the cell becomes flaccid as the cell membrane peels away from the cell wall

Answer:

1. Digestion helps to break down the food into simple, soluble form.

2. Name the process by which absorbed nutrients are utilized by the body?

Ans. Assimilation is the process by which absorbed nutrients are utilized by the body.

3. Where does initial digestion of protein take place?

Ans. Mechanical digestion of protein begins in the mouth and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.

4. Where is the water absorbed from undigested food in the digestive system?

Ans. Water from the undigested food is absorbed mainly in the large intestine.

5. Name one animal that lives on liquid food only.

Ans. Mosquito lives on liquid food only. They rely on human blood for their food.

6. The process of taking in food into the human body is called ingestion.

Ans. True.

7. The alimentary canal stretches from mouth to anus.

8. What is rumen?

Ans. Rumen is the largest compartment of the stomach of a ruminant in which cellulose is broken down by the action of symbiotic microorganisms. The primary function of the rumen is as a storage compartment to facilitate microbial (bacterial and protozoal) fermentation of ingesta.

9. Which animals are called ruminant?

Ans. Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach, they have four. Of the four compartments, the rumen is the largest section and the main digestive centre.

10.What is holozoic nutrition?​

Ans. Holozoic nutrition is a method of nutrition that involves the ingestion of some complex organic substances that may be in the solid or the liquid state.

Question doesn't see clearly than how to help

Explanation:

Answer:

I think the answer to this question is O population, community, ecosystem.

Population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex. Therefore, the correct statement is option A.

A community is made up of all the populations of different species that live in the same area and interact with one another. A population is a group of people from the same species who live there.

A biological system remembers every one of the living organic entities for a local area, as well as the actual climate in which they live and connect. In this order, the population is the most un-complex level, as it alludes to a gathering of people of similar species.

Community is more complicated because it involves interactions between multiple species populations. Because it encompasses all living and nonliving components of an area as well as their interactions, the ecosystem level is the most complex.

Therefore, population, community, and ecosystem show the levels of organizational hierarchy from least complex to most complex.

Answer:

Phospholipids consist of a glycerol molecule, two fatty acids, and a phosphate group that is modified by an alcohol. The phosphate group is the negatively-charged polar head, which is hydrophilic. The fatty acid chains are the uncharged, nonpolar tails, which are hydrophobic.

Answer:

40 b alleles

Explanation:

Only 40 b alleles are present in the gene pool, so genetic diversity is lower. The use of gene pools allows population geneticists to see variation and the influence of natural selection in detail. A single gene may show significantly less genetic variation than the variation within the whole genome of a population

Answer:

The correct answer is: A) Grass uses photosynthesis to produce glucose, which is used within the grass for growth.

Explanation:

Photosynthesis is the process by which green plants, which include algae, take in the energy from the sun and combines it with carbon dioxide (and water) to form benificial sugars.

Photosynthesis refers to the process by which the green plants, as well as algae, utilize the energy from the sun in combination with the carbon dioxide as well as water to form simple sugars. This is how the harmful gas carbion dioxide can be destroyed and elimanated.

Answer:

Look at explanation

Explanation:

An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homo-zygous for that gene. If the alleles are different, the individual is hetero-zygous.
