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.
In humans, what determines the sex of offspring and why?.
ln humans, red green color blindness is a sex-linked recessive trait. If a man and a woman produce a color blind son, which of the following must be true?
a. The father is color blind.
b. Both parents carry the allele for color blindness.
c. Neither parent carries the allele for color blindness.
d. The father carries the allele for color blindness.
e. The mother carries the allele for color blindness.
If a man and a woman produce a color blind son then both parents carry
the allele for color blindness.
A trait could either be:
DominantRecessiveWhat is a Recessive trait?A recessive trait is usually expressed when there is the presence of two
recessive alleles in an individual or organism. A dominant trait on the other
hand can be expressed with the organism having only one dominant allele
In this scenario, the red green color is a recessive trait
and the offspring produced is color blind which basically means that both
parents carry the allele for color blindness.

4. Two objects were lifted by a machine. One object had a mass of 2 kilograms, and was lifted a t a speed of 2 m/sec. The other had a mass of 4 kilograms and was lifted at a rate of 3 m/sec.
Question a. Which object had more kinetic energy while it was being lifted?
Question b. Which object had more potential energy when it was lifted to a distance of 10 meters? Show your calculation.
Explanation:
a) Case1, by the formula, ke=½mv².
m=2kg, v=2m/s
ke = ½×2×2² = 4J
Case2, by the formula, ke=½mv².
m=4kg, v=3m/s
ke = ½×4×3² = 18J
therefore, the second object has more kinetic energy.
b) Case1, by the formula, pe = mgh
m=2kg, g=9.8m/s²(not given)(can consider 10m/s² when given), h= 10m
Pe1(write 1 in subscript) = 2×9.8×10= 196J.
Case2, by the formula, pe = mgh
m=4kg, g=9.8m/s²(not given)(can consider 10m/s² when given), h= 10m
Pe2(write 2 in subscript) = 4×9.8×10= 392J.
so, the object 2 has more potential energy.

a/an ___ is a blood clot attached to the interior wall of a vein or artery.
Answer: a thrombus
A thrombus may also form in your heart
A thrombus is a blood clot attached to the interior wall of a vein or artery, which is option a. So the correct option is option a, as thrombus formation occurs when blood coagulation factors are activated and form a clot within a blood vessel.
Thrombi can occur in veins (venous thrombosis) or arteries (arterial thrombosis). In veins, a thrombus can lead to deep vein thrombosis (DVT), which commonly occurs in the lower extremities. If a thrombus dislodges from its site of origin and travels through the bloodstream, it is called an embolus, and it can potentially cause an embolism in another location. So the correct option is option a.

what is the dominant impact that humans have on alpine glaciers?
The researchers estimate that between 1990 and 2010, some 69 percent of the mass lost by the world's alpine glaciers can be traced to human influence – basically global warming. This 2013 file photo shows the Mendenhall Glaicer where it spills over the mountains above Mendenhall Lake in Juneau, Alaska.
Answer:
Human activity is playing an increasing role in the melting of glaciers, Austrian and Canadian scientists have found. One of the most disruptive effects of climate change, glacier retreat leads to rising sea levels, landslides and unpredictable availability of water downstream.

The use of biological processes to protect and repair the environment from negative human impacts is part of a growing area of biological applications called .
Bioremediation is that process which use the biological organisms to protect and repair the environment.
Bioremediation refers to the use of biological agents or processes in order to protect and repair the environment from negative human impacts. This phenomenon depends on stimulating the growth of specific type of microbes that utilize contaminants such as oil, solvents and pesticides as a sources of food and energy.
These microbes has the ability to use these harmful substances as a food and convert these contaminants into water as well as harmless gases like carbon dioxide so we can conclude that bioremediation is that process which use the biological organisms to protect and repair the environment.

which parts of the monomers involved in the dimer formation
Answer:
A dimer (/ˈdaɪmər/) (di-, "two" + -mer, "parts") is an oligomer consisting of two monomers joined by bonds that can be either strong or weak, covalent or intermolecular. The term homodimer is used when the two molecules are identical (e.g. A–A) and heterodimer when they are not (e.g. A–B).

what factors determine if a species is fit to survive?
Answer: variation, reproduction, and heritability.
Explanation: Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.
All species must reproduce to survive. Organisms cannot live forever, so they must reproduce to allow their species to continue to live on. Reproduction is nature's way of allowing a species to survive.
Higher heritability means the trait evolves faster; fewer generations are required for the trait to increase to the same degree as a trait with lower heritability. For this reason, genetic correlation and heritability show how a trait might change from one generation to the next and into the future.
