Identify the structures a virus can contain.
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.
Which of these best describes the basic unit of structure and organization of all living things?
A.
cell
B.
mitochondrion
C.

DNA
Cell is the term that best captures the fundamental level of organization and structure found in all living things. the tiniest component of all living things, including cells and other body tissues, and the smallest unit capable of independent existence.
How do cells work, and what are they made of?They support the body's structure, consume nutrients from meals, transform those into energy, and perform certain tasks.
Who coined the term cell?In 1665, the cell was found by Robert Hooke. With the aid of a compound microscope, Robert Hooke examined a piece of wine cork and discovered tiny structures that looked like little rooms. His designation of these "rooms" as "cells" follows.

Why does ice have the lowest density?
Answer:
Ice actually has a very different structure than liquid water, in that the molecules align themselves in a regular lattice rather than more randomly as in the liquid form. It happens that the lattice arrangement allows water molecules to be more spread out than in a liquid, and, thus, ice is less dense than water.
How is static electricity created?
a. Two objects that are both positively charged repel each other and release
electric energy.
b. Two objects that are both negatively charged become attracted and create a
spark.
c.
Two highly conductive materials are placed within close proximity of one
another.
d. Friction between two objects causes a transfer of electrons from one object to
the other.
.
Answer:
d
Explanation:
So, when a person or any object has extra electrons, it creates a negative charge. These electrons thus get attracted to positive electrons (as opposite attracts) of another object or person and vice versa. The shock that we feel sometimes is the result of the quick movement of these electrons.
The rubbing of certain materials against one another can transfer negative charges, or electrons. For example, if you rub your shoe on the carpet, your body collects extra electrons.
Answer:
d. Friction between two objects causes a transfer of electrons from one object to the other.
Explanation:
If electrons are transferred by rubbing two objects together, the result of the friction is that one object becomes positively charged by losing electrons, and the other object becomes negatively charged by gaining them. This is known as static electricity.

What is Creatine Kinase? What is it used for in our muscle cells?
Answer:
This test is used to find damage to muscles in your body, including your heart muscle. Creatine kinase (CK) is an enzyme found in your muscles. Enzymes are proteins that help your body's cells do their jobs. The level of the CK enzymes rises when you have damage to muscle cells in your body
Explanation:
Using the photosynthesis equation, predict how the rate of photosynthesis might change with variation in the following parameters (assuming that the plants is not receiving the maximum amount it can use):
a. The amount of light hitting a leaf
b. The availability of water
c. The amount of carbon dioxide in the atmosphere
d. The air temperature when water is limiting factor
Answer:
the answer is below
Explanation:
a) A plant process that changes sunlight into chemical energy. If there is less light the plant wont be able to function properly
b) Without enough water in the cells, the plants droop, so water helps a plant to stand. Water gives plants moisture to keep them alive.
c) If there is not enough CO2 the plant wont be able to photosynthesise as fastly as it usually does.
d) If the temperature is high and there is lack of water the plant is most likely to die. This is because it will be dehydrated.
The movement of water through a plant is caused by
Answer:
The bulk of water absorbed and transported through plants is moved by negative pressure generated by the evaporation of water from the leaves (i.e., transpiration) — this process is commonly referred to as the Cohesion-Tension (C-T) mechanism.

Certain materials are needed by the mitochondria to make energy. Which of the following is most responsible for getting the
materials into the cell?
O A The materials need to Love through the cytoplasm to get to the mitochondria
B The cell membrane lets the materials into the cell so they can get to the mitochondria
OCThe cell wall lets the materials into the cell so they can get to the mitochondria
D. The materials need to move through the lysosome to get to the mitochondria
Answer:
C. The cell membrane lets the materials into the cell so they can get to the mitochondria
Explanation:
The cell membrane regulates the entrance and exit of certain molecules inside the cell. Some molecules can easily pass through the phospholipid bilayer via passive transport. Others use protein channels, and some require movement by active transport, or endocytosis.

Each strand of s DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A diagram of a section of DNA is shown. DNDA Strand 3' _|___|___|___|___|___|___|___|___|___|___|___|___|_ 5' T G T A G C T G C G C G T Which DNA strand is complementary to the one shown above?
Answer:
The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'
Explanation:
Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.
In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:
Adenine is complemented with Thymine. Guanine is complemented with Cytosine.According to this, the complementarity of the strands is:
5' - T G T A G C T G C G C G T - 3'
3' - A C A T C G A C G C G C A - 5'
The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.

What do you mean by Genotype?Genotypes may be defined as the ultimate combinations of the alleles of those genes which are selected for studies.
The genotypes of both parents are heterozygous i.e. Ww. The ratio of the complete genetic cross is 3:1.The percentage that the offspring will have webbed hands is 75%. (WW, Ww, Ww)The percentage that the offspring will have normal hands is 25% (ww).The Punnett square is attached below:
