What is the difference between extrusive and intrusive igneous rock?

Intrusive igneous rock forms below ground and extrusive igneous rock forms above ground.

Intrusive igneous rock forms above ground and extrusive igneous rock forms below ground.

Intrusive igneous rocks form when sediments are compacted together and extrusive igneous rocks form when sediments separate.

There is no difference, they both form above ground.

Answers

Answer: I'm pretty sure it's the first one

Explanation: I don't know for sure but I'm pretty sure when I learned it they said that extrusive is above ground and intrusive is below ground. Don't take my word for 100% though

If a DNA strand has 32 % guanine, what percent thymine does it contain?
A) 36%
B)18%
C)64%
D)32%

Answers

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

Answers

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.

This is for my biology class. It is for the osmosis potato lab (Google it if you don't know what it is) and I have to answer this question. I also have to include the words at the bottom. This is really confusing and I would be so happy if someone could please help me with this!

How can a scientist use this lab to determine the amount of solute in an Idaho potato?

Use the following vocabulary words in your final conclusion statement below:
Hypertonic, hypotonic, isotonic, dynamic equilibrium, solute, solvent, osmosis

Answers

Explanation:

A scientist can use this experiment to determine the amount of solute in any potato.

hypotonic solution is a relative term. it means when we compare two solutions one of them is considered to be a hypotonic if it's solute concentration is less than the other.

so if the solution has less solute concentration its hypotonic solution and if it has more amount of solute its hypotonic solution. if both solutions have same amount of solute then it will be considered as a isotonic solution. when we separate two solution hypertonic and hypotonic by a semipermeable membrane there occurs diffusion of water molecules from its higher concentration to its lower concentration that is from hypotonic solution to hypertonic solution.

this movement of water molecules is called osmosis. this occurs in order to obtain an dynamic equilibrium between the 2 solutions.

here we take start as solute and water as solvent.

thus when a scientist and potato in a hypotonic solution the water moves inside the potato cavity. the more the transfer of water molecules in the potato cavity the more in the sugar quantity present in the potato. this is because the water will try to obtain a dynamic equilibrium between the two solutions if the sugar quantity in the potato cavity is high then the water molecules needed to dilute that solution will also be high.

in in this way a scientist can determine the amount of salt present in the potato.

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 ?​

Answers

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.

According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?


Binding the RNA polymerase to the gene

Preventing the repressor from binding to the lac operon

Removing the inducer

Transcribing the lacl sequence

Answers

Answer:

Transcribing the lacl sequence

Explanation:

lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.

However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.

Answer: removing the inducer

Explanation: all sequences need an inducer present in order for them to be expressed

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.  

Thus option C is correct.

Answers

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.

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?

Answers

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).

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.
