If a DNA strand has 32 % guanine, what percent thymine does it contain?
A) 36%
B)18%
C)64%
D)32%
Answer:
B
Explanation:
Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.

What is the difference between the euphotic zone and the bathyal zone of the ocean
Answer:
Euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis.
Bathyal zone is the part of the pelagic zone that extends from a depth of 1000 to 4000 metres below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.It is ala known as midnight zone.

An igneous rock has small, dark crystals. Which statement also accurately describes this rock?
It is an intrusive rock.
It has a coarse texture.
It was found on Earth’s surface.
It was formed from slow cooling.
Answer:
It was found on Earth’s surface.
Explanation:
Igneous rocks are formed either on the surface of the Earth or deep in the Earth's crust. Those formed on the surface of the Earth are called "Extrusive Igneous Rocks" while those formed in the crust are called "Intrusive Igneous Rocks."
An igneous rock which has small, dark crystals is an extrusive igneous rock (this makes the first choice incorrect). It was formed through "rapid cooling," thus, it's texture is fine (this makes the last two choices incorrect).
Since it is an extrusive igneous rock, it can be found on the Earth's surface. This makes the third choice correct.

What is an atomic nucleus ?An atomic nucleus is the central region of the atom at which the number of protons and neutrons are in abundance. The charge carried by the nucleus is positive in nature.
The picture shows the lock and key method where it is the relation between enzyme and substrate where the enzyme and substrate are almost same in shape where the lock is the substrate where the enzyme is of key shaped and they both fit in.
An active site is the region of the reactant or substrate where the enzyme will bind in and the reaction will form a product. The binding of both the constituents depend on the binding energy and activation energy of the reaction.

Mike works as a nurse in a hospital he accidentally gave a patient a hypotonic solution. such as distilled water instead of an isotonic solution suck as saline
what changes will occur in the patients cells ?
what can be done to fix this problem ?
Answer:
The patient's cells will swell and then burst. The solute concentration outside the cell is lower than inside the cell, so water will move into the cells.
Mike would have to give the patient a hypertonic solution, which will cause water to move out of the cell and the cell to shrink followed by an isotonic solution, which should regulate the concentration inside and outside the cell.
Hope that helps.
What does evaporation change from ? Solid ———> liquid Liquid ———-> Solid What does condensation change from Liquid——-> solid Solid———> liquid
Answer:
Evaporation : Liquid --- Gas (Vapor) ; Condensation : Gas (Vapor) --- Liquid
Explanation:
Evaporation is the change of a liquid into gas or vapor, usually by increase in temperature. Eg : Water evaporation into vapors during water cycle, due to sun heat.
Condensation is the change of gas or vapor into liquid, usually by decrease in temperature. Eg : Vapors condensation into water droplets during water cycle, due to lower atmospheric temperature at higher height.

helium is an element..............
Answer:
A. Element
Explanation:
He is a symbol of an element called helium. Helium is a colorless, odorless, tasteless, non-toxic, inert, monatomic gas (gas whose atoms are not bound to each other). It's the first in the noble gas group in the periodic table. As we can see in the attached image, its atomic number is 2.
Helium is known for causing people to have a high-pitched voice after being inhaled. Because it is lighter than air, when you inhale it and try to talk, the sound waves travel faster through the lower-density gas, resulting in a high-pitched voice.

What are the types of epithelial tissue in human ?A tissue is a cluster of similar cells that perform specific function.
Epithelial tissue one most important type of tissue.
It can be up two types such as Simple epithelium and Stratified epithelium.
Simple epithelium is a single layer of identical cells, observed at sites of secretion, absorption of substances.
It can be up three types Squamous epithelium, Cuboidal epithelium, Columnar epithelium.
Simple Squamous epithelium is single layer of flattened cells found Lungs-alveoli, Blood vessels-endothelium.
Simple cuboidal epithelium found in tubules of nephrons and glands which is involved secretion, absorption, and excretion, etc.
Simple columnar epithelium found in the inner layers of the stomach, intestine, trachea,
Stratified epithelium which is multiple layers epithelial tissue can be up 4 types squamous, cuboidal, columnar, Psuedo-stratified columnar epithelium.

Suppose the great, green galoofus lizard has 28 chromosomes in the nucleus of its unfertilized eggs. Predict how many chromosomes will be in the skin cells of a great, green galoofus lizard?
Answer: 56
Explanation:
Because an unfertilized egg has half the chromosomes of a fertilized egg. The fertilized egg then splits, and continues splitting until the lizard is born. Always remember, whenever a question talking about an unfertilized egg, it has half the chromosomes of a fertilized egg. One more side note, it doesn’t matter what body part you talk about. A skin cell will have the same number, and identical chromosomes compared to a heart cell. (So long as it’s the same organism, if it isn’t, but part of the same species, it will have the same number of chromosomes, but it may have a unique set of chromosomes). If you want me to go into detail, I can, just respond to this answer.
