Answer:

One snail for two plants.

Explanation:

One snail and two plants we need to keep a stable environment because the snails help to clean up garden debris by feeding on them and their feaces has nitrogenous nature which is nutritive for the plants. So the plants get nutrients from the snail as well as carbondioxide gas used by the plants for the process of photosynthesis. So we can say that snails are important for maintaining a stable environment.

Gizmo technology helps build up an understanding of challenges and helps in developing interests.

For a stable environment, we will require one snail for two plants.

Snails are a very important part of nature as they balance the environment and the food web.

Snails feed on plants and dead decaying matter. That helps in keeping a balance.

The excretory waste from snails is nitrogenous in nature and aid in plant nutrition.

Hence, the plant can get nitrogen from Snails faeces, and also carbon dioxide required for the metabolic processes.

From the diagram X = base pairs

Explanation:

Genetic information stored within DNA is used for growth, reproduction, and cell repair. DNA, deoxyribonucleic acids, are long-chain, helical macromolecules made of specific sequences of covalently bonded monomers called nucleotides.

Nucleotides comprise:

Nitrogenous bases cause nucleotides to form hydrogen bonds with other nucleotides as base-pairs. The four types of bases each make the nucleotides  Thymine and Cytosine (pyrimidine bases) along with Guanine,  and Adenine, (purine bases). In base-pair formation, Adenine forms double bonds with Thymine, and cytosine forms triple bonds with guanine.

Answer:

B. respiration

Explanation:

The bubbles produced when yeast cells are placed in a glucose solution is because the yeast cells are carrying out respiration. The correction option would be B.

Yeast cells are able to carry out a type of respiration known as anaerobic respiration when placed in a suitable substrate medium like glucose. During this process energy in the form of ATP is generated in the absence of oxygen for the metabolism of the yeast cells. The equation of the reaction is as follows:

[tex]C_6H_1_2O_6 --->2 C_2H_5OH + 2 CO_2[/tex]

Thus, the carbon dioxide gas is released as bubbles in the solution as a result of respiration.

Answer:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur.

2. Its ability to catenate; its ability to form bonds easily with other elements such as hydrogen, oxygen and nitrogen; its ability to form single, double and triple.

3. Carbohydrates, Proteins, Lipids, and Nucleic acids

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Proteins are considered polymers while Lipids are not because proteins are composed of monomeric subunits of amino acids whereas lipids do not have monomeric subunits.

Explanation:

1. The major elements of life are Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus and Sulfur as they are found in many structures of living organisms- in proteins, carbohydrates, nucleic acids and lipids.

2. Carbon has the ability to form different large and complex structures because:

(I) its ability to catenate which is the ability to combine with one another to form straight, branched chain or ring compounds containing many carbon atoms.

(ii) carbon can form single, double and triple with itself and other life elements.

(iii) the relative stability of the covalent bonds formed by carbon.

3. Four groups of organic compounds found in living things are Carbohydrates, Proteins, Lipids, and Nucleic acids.

4. Carbohydrate provide energy; Proteins serve as structural elements;

Lipids serve as structural components of membranes;

Nucleic acids store and transmit genetic information

5. Polymers are large molecular weight compounds built up from subunits called monomers.

Proteins are considered polymers because they are large molecular weight molecules composed of monomeric subunits of amino acids.

Lipids are not considered polymers because individually, they are not very large molecules and do not have monomeric subunits rather are composed of long fatty acids chains linked to a glycerol molecule.

Answer:

Nitrogen is the right answer.

Answer:

Tofu and soy oil come from soy bean plants that are grown on farms. Many farmers grow soy beans as cash crops that they can send to places such as tofu processing plants. Soybean plants are legumes. Legumes have bacteria on nodules which are on the roots of the plant. The bacteria on the nodules takes nitrogen from the air and fixes it into the soil, so that other plants that require nitrogen can use it as well.

This nitrogen cycle that was breifly discussed above is used in what farmers call a crop rotation. Farmers use soybeans and other legumes in roatations with grass crops such as corn or wheat. Grass crops are unable to take their own nitrogen from the air so they either need the nitrogen in the soil that the legumes provide for them in a crop rotation or they need a chemical fertilizer containing nitrogen. Many farmers choose to use both. Most farmers use a two or four year rotation on their fields. In a two year rotation a farmer will alternate a year of a legume such as soybeans and a year of a grass crop such as corn. In a four year rotation a farmer will alternate back and forth between legumes and grass crops just as in a two year rotation, but instead he will use four differnt crops. For example, a farmer may plant a rotation of soybeans, corn, alfalfa (a legume), then wheat (a grass).

Answer:the 3 one

Explanation:

Answer:

Explanation:

For the first paragraph

1) The only experimental group is the group that took the supplement of 3000 mg. Experimental groups are groups that receive treatment during the course of an experiment. The treatment in this experiment is the nutritional supplement and group A was the only group that received that hence the correct option is A.

2) To have confidence in the result, it will be important to note if there were volunteers who had cold at the beginning of the experiment. Because if there were volunteers who had cold at the beginning of the experiment and were part of the experimental group, that could mean those volunteers didn't respond to the treatment because of underlying health condition which could be the cause of there own cold and might have to be treated based on the underlying condition thus negating the aim of the experiment which was to treat cold and not any underlying health condition. Hence, the correct option here is A

For the second paragraph

3) Since the only living property that the robot has according to the passage is movement then option A is the correct answer. There is no evidence from the passage that the robot can derive nutrition from food source from the passage. Also reproduction as a living property must be undertaken by the individual living organism in question; here researchers are the ones undertaken the reproduction and thus is not the property of the robot. Also, there is no evidence from the passage that the robot has fibroblasts.

4) The correct option here is B. Emergent properties of cells are collective properties that convey a particular attribute that cannot be achieved individually. The question says the cardiac cells will have to come together to cause the attribute of movement that cannot be achieved individually

Answer:

If a father has type A blood and the mother has type AB blood, they cannot have a child with blood type O, although depending on the father's genotype, they may not have children with a B blood type either.

Explanation:

Blood type is determined by the presence or absence of surface antigens A and B, which is genetically determined and establishes the pattern of inheritance.

Alleles that define the presence of antigens A and B are co-dominant, while the absence of antigens - as in blood type O - is a recessive trait.

The father with blood type A can have two genotypes, A|A or A|O, which raises 2 possible scenarios:

1. Father A|O with mother A|B

Alleles       A         O

A              A|A      A|O

B              A|B      B|O

In this case there is no chance of having a child with blood type O, 50% chance of having children with blood type A, 25% B and 25% AB.

2. Father A|A with mother A|B

Alleles        A        A

A               A|A     A|A

B               A|B     A|B

50% chance of having a child with blood type A and 50% with blood type AB. In this case there is no chance of having children with blood type O or B.

Answer: .All of the yellow offspring are heterozygous for color.

Explanation: do your chart

The offsprings could be yellow or green since the genotypes obtained after cross will be YY, Yy and yy Therefore, option (4) is correct.

The following is an outline of Mendel's laws of inheritance:

The principle of dominance is the foundation of the laws of inheritance. The law specifies that hybrid offspring will only inherit the dominant phenotype. The alleles that do not show in an individual are referred to as recessive traits, whereas the alleles that do manifest are referred to as dominant traits.

The alleles for each gene separate from one another during the process of gamete creation, ensuring that each gamete carries just a single copy of each allele for the genes that it contains. This is known as the law of segregation.

The law of independent assortment states that genes for various characteristics might segregate in an unrelated fashion while gametes are being formed.
