Which feature may interrupt the sides of a composite-cone volcano?
conduits
fumaroles
craters
calderas
The feature may interrupt the sides of a composite-cone volcano is fumaroles. Thus, option B is correct.
What is fumaroles?They are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction.
Fumaroles are gaseous emissions from lavas in craters at more or less elevated temperatures. Its composition varies according to the temperature of the lavas, in such a way that it changes since the fumaroles appear until their extinction. Water flows in the form of steam continuously through the cracks of a volcano or volcanic surface because its temperature exceeds 100 °C.

A single-celled zygote develops into a multicellular organism with specialized cells through the processes of
Answer:
mitosis
Explanation:
The zygote undergoes a process known as mitosis, in which it replicates its chromosomes (which carry each parent's DNA) and then divides, resulting in two identical cells. These cells are called totipotent and have the ability to develop into a new organism

compare the hygiene allergies and asthma?
Answer:
According to the “hygiene hypothesis,” the problem with extremely clean environments is that they fail to provide the necessary exposure to germs required to “educate” the immune system so it can learn to launch its defense responses to infectious organisms. Instead, its defense responses end up being so inadequate that they actually contribute to the development of asthma.
Explanation:
A cross was made between two strains of plants that are agriculturally important. One strain was disease-resistant but herbicide-sensitive; the other strain was disease-sensitive but herbicide- resistant. A plant breeder crossed the two plants and then allowed the F1 generation to self- fertilize. The following data were obtained:
F1 generation: All offspring are disease-sensitive and herbicide-resistant
F2 generation: 157 disease-sensitive, herbicide-resistant
57 disease-sensitive, herbicide-sensitive
54 disease-resistant, herbicide-resistant
20 disease-resistant, herbicide-sensitive

A classic example of osmosis in the classroom involves placing an egg in water or syrup. The egg first sits in vinegar until the shell is dissolved. Then, it is placed in a glass of either tap water or syrup. The mass of the egg is measured. The results are in the chart below. Use what you know about osmosis to explain why the egg increased in mass in the distilled water but decreased in mass in the corn syrup.
Answer:
Water is hypotonic compared to the inside of the egg; there are more solutes in the egg than in the water. Because water moves down its concentration gradient, it moves from the distilled water into the egg. It will continue to move in this direction until there is an equilibrium between the inside of the egg and the surrounding water. This increases the mass of the egg.
Corn syrup is hypertonic to the inside of the egg. Again, water moves down its concentration gradient from the inside of the egg to the solution. This will decrease the mass of the egg.
The reason solutes do not move, instead of water, in these situations is because the egg shell (assuming it is like a chicken egg) does not allow solutes to pass though it. Only water is able to move through the shell.

What are the causes of inherited genetic variation
Answer:
Genetic variation can be caused by mutation which can create entirely new alleles in a population, random mating, random fertilization, and recombination between homologous chromosomes during meiosis which reshuffles alleles within an organism's offspring.

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
If the offspring of the cross showed ccdominance, what would the eyes of the offsping look like?
Answer.. the offspring would have one circle eye and one star eye.
Answer:
That is what I would choose
Explanation:
When two different phenotypes of an organism are crossed, a third phenotype is created in which both of the parental traits are present. This is known as codominance.
What are the results of codominance cross?The concept of codominance states that although both phenotypes are dominant, they cannot coexist. Codominance would result in patches rather than merging, with areas of prominent white expression and areas of dominant red expression.
The statements made about codominance are all accurate. The full expression of both alleles is present.
The distinct results of both alleles are present in the heterozygous phenotype. A multiple-allele characteristic has (less than / only / more than) two alleles in the corresponding gene.
Therefore, The offspring would have one circle eye and one-star eye.

What characteristics make white dwarf stars different from main sequence stars?
Answer:
Eventually, a main sequence star burns through the hydrogen in its core, reaching the end of its life cycle. At this point, it leaves the main sequence. Stars smaller than a quarter the mass of the sun collapse directly into white dwarfs. White dwarfs no longer burn fusion at their center, but they still radiate heat.
List three types of blood cells and indicate what they do to help your body maintain homeostasis
Answer:
Both cells present in the blood come from the marrow of the bone. They start their lives as stem cells and develop into three main cell types: RBCs, WBCs, and platelets.
RBCs- The red blood cells supply the cells with oxygen and extract carbon dioxide. ... In controlling the processes of the body and preserving homeostasis, blood plays an important role. It carries out many functions within the body, including: supplying tissues with oxygen (bound to hemoglobin carried in red cells)
