How does cooling of magma affect crystal size?
A) Slow cooling creates small crystals
B) Fast cooling creates both large and small crystals.
C) Slow cooling creates large crystals
D) Fast cooling create large crystals
Answer:
When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.
Answer:
I learned about this, Uhm...
C is the right answer bc igneous rocks cool and form crystals.
Lava, since it comes out of a volcano, cools faster and has smaller crystals since they could not be developed enough.
Magma, still underground, cools slower than lava because of all the density and heat, which causes bigger crystals.

how does biodiversity help with farming
Answer:
biodiversity is the basis of agriculture and our food systems. agricultural biodiversity also performs ecosystem services such as soil and water conservation, maintenance of soil fertility, conservation of biota and pollination of plants, all of which are essential for food production and for human survival.
good luck :)
hopefully, this helps
have a great day !!
Cystic fibrosis is a recessive genetic disease caused by a mutation in the gene that encodes the CFTR protein, which transports chloride ions in and out of cells. Some populations have a relatively high rate of cystic fibrosis carriers, possibly because the mutation protects against severe dehydration in diseases like cholera or typhoid. What concept does this best illustrate?
A: Polygenic traits
B: Genetic drift
C: Pleiotrophy
D: Heterozygote advantage
its letter b the genetic drift because it is mechanism of evolution in which allele frequencies of a population change over generation due to chance.
Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D.
What is the heterozygote advantage?When the gene is present in a heterozygote state, the gene product benefits the individual rather than harming him or her, as in sickle cell anemia and cystic fibrosis. In sickle cell anemia, the heterozygote state protects the person from malaria, and in cystic fibrosis, it protects the person from dehydration.
Hence, Cystic fibrosis is a recessive genetic disease that encodes the CFTR protein, but some populations have a relatively high rate of cystic fibrosis carriers, which protects against severe dehydration and is an example of the heterozygote advantage that is present in Option D..

How are the smallest ocean waves produced?
Answer:
Ocean waves are usually formed by a distant wind. ... The area which the wind affects the surface is called the fetch. The larger the fetch, the greater the waves produced. the small waves generated by storm winds are often confused and disorganized.
Explanation:
Answer:
For a wave to effectively be produced there need to be large wind, long period of time and a large distance of water. If they are all reduced, then there would be a reduction in the intensity of the wave.

Explain how an abiotic factor (stronger storms, warmer oceans, or lower ocean pH) can affect populations in a coral reef ecosystem
Answer:
Climate change leads to: A warming ocean: causes thermal stress that contributes to coral bleaching and infectious disease.
Explanation:
Sea level rise: may lead to increases in sedimentation for reefs located near land-based sources of sediment. Sedimentation runoff can lead to the smothering of coral.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin
c. pilin
Answer:
b. tubulin
Explanation:
Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles
Tubulin protein is damaged at the nerve endings during mercury toxicity.
What do you mean by Mercury Toxicity?Mercury toxicity occurs when an individual is highly exposed to mercury.
The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.
Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.
Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.

The average molecular weight of proteins encoded in the human genome is about 50,000. A few proteins are very much larger than this average. For example, the protein called titin, which is made by muscle cells, has a molecular weight of 3,000,000. Estimate how long it will take a muscle cell to translate an mRNA coding for an average protein and one coding for titin. The average molecular mass of amino acids is about 110 daltons. Assume that the translation rate is two amino acids per second.
Answer:
13,636 seconds = 227.3 minutes = 3.79 hours
Explanation:
The titin protein has a molecular weight of 3,000,000 daltons, while the average molecular mass of one amino acid is 110 daltons, so it is expected that this protein is composed of 27,273 amino acids (3,000,000 daltons/110 daltons = 27,272.72). Moreover, and since the translation rate is two amino acids per sec, it is expected that the protein will be synthesized in approximately 3.79 hours (27,272.72/2 = 13,636 seconds = 227.3 minutes = 3.79 hours).
