Answer:

Water is a covalent compound.

Explanation:

covalent compounds are individual molecules characterized by the sharing of electrons between two or more atoms. Two atoms with similar electronegativity will not exchange an electron from their outermost shell; the atoms instead share electrons so that their valence electron shell is filled.

Example:

Examples of compounds that contain only covalent bonds are methane (CH4), carbon monoxide (CO), Water (H2O) and iodine monobromide (IBr).

Properties:

1. At room temperature and normal atmospheric pressure, covalent compounds may exist as a solid, a liquid, or a gas.

2. Covalent compounds do not exhibit any electrical conductivity, either in pure form or when dissolved in water.

3. Covalent compounds have lower melting and boiling points.

Answer:

Water

Explanation:

A covalent compound is a compound formed by two or more elements that share covalent bonds, they are often formed when two non-metals react together and form a compound, for example Hydrogen and Oxygen creating water, and they are called covalent compounds because the bond that forms the compounds is created because of the share of the electrons by the nuclei.

Ne4ueva [31]

Answer: Hypertonic Environment

Explanation:

The salt solution and sugar solution is used for the process of food preservation as the bacteria and microorganism are not able to grow in such conditions that is being created by the solution.

The amount of the solute is more and the solution is less concentrated. The bacteria cell has less solutes and more solvent.

As per osmosis the water from the salt or sugar solution moves out from bacterial cell shrinks and dies.

This is how the bacterial cell dies and the food is prevented from spoilage.

harkovskaia [24]

Vertebrata

Vertebrata is a group that contains various organisms which possess vertebrae (backbones). Animals that belong to the group are called vertebrates, and they include mammals, birds, fish, amphibians, and reptiles. The backbones in the animals extends from the head to the tail, and it encloses and protects the main nerve cord. The body of vertebrates is divided into trunk, and tail regions. They also possess a unique tube shaped brain, a distinct head, and three pairs of sense organs.

A man who has type B blood has children with a woman who has type A blood. A. If they are both heterozygous for this trait, pred
Ivenika [448]

Answer:

The possible blood types of their children are: type AB (iAiB), type A (iAi), type B (iBi), type O (ii)

Explanation:

Blood type in humans is controlled by a gene with multiple alleles. Alleles iA and iB are dominant over allele i but co-dominant. The following blood types are encoded by the following alleles:

Blood type AB - iAiB

Blood type A - iAiA or iAi

Blood type B - iBiB or iBi

Blood type O - ii

According to this question, a man who has type B blood has children with a woman who has type A blood. They are both heterozygous, meaning that the man's genotype is "iBi" while the woman's genotype is "iAi". Both parents will produce gametes as follows:

iBi = iB and i

iAi = iA and I

Using these gametes in a punnet square (see attached image), the following possible blood types are produced in the offsprings:

- type AB (iAiB)

- type A (iAi)

- type B (iBi)

- type O (ii)
