How does the eruption of an explosive volcano on an island in the Pacific Ocean ,begin most likely affect humans living thousands of miles away?
A.
The heat travels to the nearest landmass.
B.
The ash blocks sunlight and cools temperatures.
C.
The lava raises the sea level near coastal communities.
D.
The plate movement that caused the volcanic eruption increases.
Answer:
B
Explanation:
Water is very good at absorbing heat, making it incredibly unlikely that the heat from a volcanic explosion will spread thousands of miles.
The addition of lava into the ocean would not be significant enough to raise sea levels on the other side of the ocean without there being significantly larger problems (like the planet being cracked).
Volcanic eruptions do result in tectonic plate movement, but it is unlikely that an eruption thousands of miles away will trigger any noticeable change.
This leaves B, which describes the phenomenon believed to have killed the dinosaurs and to have caused major climate abnormalities in 1816. When large amounts of ash go into the atmosphere, they are spread by air currents in the same way a hurricane can travel from Africa to North America. The ash cloud would obscure the Sun, reducing the amount of solar radiation reaching the surface and thus decreasing temperatures.

Only 2 molecules of ATP are produced in anaerobic cellular respiration
Anaerobic RespirationIt is the process whereby the cellular breakdown of carbohydrates takes place in the absence of oxygen.
During anaerobic respiration, carbohydrates in the form of glucose are broken down into two molecules of pyruvates and 2 molecules of ATP are generated.
In the presence of oxygen, the pyruvate molecules would have entered into the citric acid cycle but due to the absence of oxygen, the two pyruvate molecules are converted to lactic acid.

what Mendal law states that two hereditary factors separate when gametes are formed
Mendel's law of segregation states that the two hereditary factors separate when gametes are formed. When fertilization occurs, the offspring receive one hereditary factor from each gamete, so the resulting offspring have two factors. The law of segregation predates our understanding or meiosis.
Hope it helps...Answer:
Mendel's law of independent assortment states that the alleles of two or more different genes get sorted into gametes independently of one another. The allele a gamete receives for one gene does not influence the allele received for another gene.
Explanation:
Mendel’s law of independent assortment states that genes do not influence each other with regard to the sorting of alleles into gametes: every possible combination of alleles for every gene is equally likely to occur. The independent assortment of genes can be illustrated by the dihybrid cross: a cross between two true-breeding parents that express different traits for two characteristics.

Georgette drew a diagram to compare chytrids and sac fungi.
Which description belongs in the area labeled Z?
a-Have reproductive cells with flagella
b-Contain cell walls
c-Release chemicals to break down food
d-Lack hyphae
Answer:
D
Explanation:
Chytrids lack hyphae.
Answer:
d-Lack hyphae
Explanation:
It refers to the difference between them and also the characteristics which chytrid has.
They both have cell wall.They both are reproductive cells with flagella.fungi release chemicals to break down food but chytrids do not.fungi has general hyphae whereas chytrids does not. So chytrids lack hyphae and matches the characteristics.Throughout history, microorganisms, such as yeasts, have been used in the processes for making cheese and bread. These microorganisms use anaerobic respiration to break down glucose to produce which two possible products?.
Yeast fermentation produces ethanol and carbon dioxide.
Fermentation is an anaerobic pathway that breaks down glucose in absence of oxygen.Conversely, cellular respiration requires oxygen to break down glucose molecules.Fermentation is energetically less efficient than cellular respiration in terms of the generation of energy (ATP).In conclusion, yeast fermentation produces ethanol and carbon dioxide.

In a biology lab, students view a droplet of pond water under a microscope. One student observes a green, one-celled organism that has a flagella. What can the student infer from these observations?
Question 5 options:
The organism must be from the Animal kingdom since it has a flagella.
The organism must be photosynthetic since it is green.
The organism must be able to move since it has a flagella.
The organism must be a decomposer since it is single-celled.
The organism must be able to move since it has a flagellum. This structure is used for motion.
What are flagella?The flagella (singular flagellum) can be defined as hair-like structures used for organisms for the locomotion of their cells.
Flagella is an organelle found both in eukaryotic (unicellular and multicellular) and prokaryotic organisms.
For example, most bacteria are motile due to the presence of flagella that helps to achieve this function.

Clarence made a diagram to compare codominance and incomplete dominance. Which label belongs in the area marked Y? Neither allele is dominant. An intermediate phenotype is expressed in offspring. One allele is dominant over the other. Both dominant alleles are fully expressed in offspring.
Explanation:
both dominant alleles are fully expressed in offspring.
In the incomplete dominance inheritance, one allele is not completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a new phenotype. For example AB blood group in humans.
In the given question Y is the intersection of co-dominance set and incomplete dominance set. Thus, the area Y may have one dominant allele from co-dominance and one allele which is not completely dominant from incomplete dominance.
Therefore, the label to marked area Y may be - both dominant alleles are fully expressed in offspring.
Answer:
The correct answer is both dominant alleles are fully expressed in offspring. In the incomplete dominance inheritance, one allele isn't completely expressed over its paired allele and forms an intermediate trait, whereas in co-dominance, both the alleles express completely resulting into a brand new phenotype. for instance AB blood type in humans. In the given question Y is that the intersection of co-dominance set and incomplete dominance set. Thus, the realm Y may have one dominant allele from co-dominance and one allele which isn't completely dominant from incomplete dominance. Therefore, the label to marked area Y is also - both dominant alleles are fully expressed in offspring.
