How does oxygen enter the cells of the tube worm
Answer:
Flatworms are small, literally flat worms, which 'breathe' through diffusion across the outer membrane (Figure 2). The flat shape of these organisms increases the surface area for diffusion, ensuring that each cell within the body is close to the outer membrane surface and has access to oxygen.

if an organism has a diploid number of 12, how many possible combinations of chromosomes could exist in its gametes with no crossing over?
a.) 8
b.)16
c.)32
d.)64
Answer: D
Explanation:
Chromosomes are the inherited unit of the organism which transfers the parental gene to the offspring.
The diploid is the paired chromosome quantity present in the cell that originates from each parent.
The correct answer is:
Option D. 64
This can be explained as:
The diploid (2n) number of chromosomes = 12Haploid (n) number of chromosome = 6The possible number of chromosome pairs is given by 2ⁿ. Where n = a haploid number of chromosomes.So, the possible combinations of chromosomes that could be found in the gametes with no crossing over will be:
= 2⁶
= 64
Therefore, 64 possible combinations of chromosomes can be present.

when coal is burned in a power plant for electricity in one city how might this affect a forest many miles away
A. it's could contribute to acid rain falling on the forest
B. it could increase the amount of oxygen available to the forest
C. it could provide electricity for heating the forest
D. it could decrease the amount of carbon dioxide available to the forest
Answer:
A.
Explanation:
When a power plant is made they all have these pies that come out of the buildings to extract the smoke but what most people don't know is that smoke is put out in the air and is taken to the clouds which mixes with the rain and since it is toxic it eventually leads it to be acid rain the more smog it picks up. Acid rain is very dangerous it burn down a whole forest, so yes, your answer is A.
Hope this helps :)
When coal is burned in a power plant for electricity in one city, it might significantly affect a forest that is located many miles away by contributing to acid rain falling on the forest. Thus, the correct option for this question is A.
What are the disadvantages of burning coal?The disadvantages of burning coal are as follows:
It stimulates air pollution. It also increases the level of greenhouse gases in the atmosphere. It is primarily responsible for acid rain. It overall declines the biodiversity of living organisms by making the environment toxic for living.According to the context of this question, when coal is burning, it deposited a high amount of carbon dioxide in the environment due to which carbonic acid is produced which is fallen on the earth along with precipitation. It causes a severe threat to all forms of living organisms in each ecosystem.
Therefore, the correct option for this question is A.

What is the difference between the euphotic zone and the bathyal zone of the ocean
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.

11) What is your opinion on the reintroduction of the gray wolf? Should ranchers be
able to kill any wolves they see, only the ones that kill their livestock, or none at all?
Should the wolves never have been reintroduced? Write a paragraph stating your opin-
ion on these questions and give reasons to support your opinion.
Answer:
In my opinion, I think that the reintroduction of the gray wolf is good because then the wolf species is a bit more diverse and that I think that the ranchers should only kill the wolves that eat their livestock. I also think that it's wrong to kill whatever wolves ranchers see, all because what if it's a wolf that wasn't even planning on attacking the livestock, or what if it was a wee little wolf pup that did nothing wrong.
I hope this answers your question. :D
The reintroduction of the gray wolf is good because it controls the population of herbivorous animals.
How introduction of wolves is good?In my opinion, I think that the reintroduction of the gray wolf is good because the wolf is a specie that plays a very important role in maintaining homeotstasis in the ecosystem. I think that the ranchers should only kill the wolves that eat their livestock and not to kill whatever wolves seen by ranchers.
So we can conclude that the reintroduction of the gray wolf is good because it controls the population of herbivorous animals.

Cytosine is an enzyme the helps in replication
Answer:
Cytosine is an enzyme the helps in replication.
Explanation:
Cytosine is the name of the nitrogenous base of DNA. Basically, cytosine makes up DNA.
"Cytosine is an enzyme that helps in replication" is not true about DNA replication. Therefore, option (4) is correct.
Cytosine, one of DNA's four nucleotide bases, does not replicate DNA. Before a cell divides, DNA is replicated perfectly. Eukaryotic and prokaryotic organisms have it. DNA replication requires numerous enzymes. DNA polymerases add nucleotides to build new DNA strands. Helicases unwind the DNA double helix to form a replication fork. Primases make DNA-synthesis-starting RNA primers. Ligases link newly synthesised DNA segments.
Eukaryotes replicate DNA in the nucleus during the S phase. The cytoplasm replicates prokaryotes. These procedures faithfully transmit genetic information to daughter cells. Therefore, option (4) is correct.

Any living creature that lives beneath the Pacific surface will absorb the sunlight for nourishment. If the sun banishes all the living organisms (plants and algae) will suffer due to the lack of photosynthesis. The sun has a massive effect on the aquatic life in the oceans, lakes, or any body of water; including the Pacific Ocean.

Organisms that can adapt to changes in their environment are most likely to survive and reproduce, while those that cannot adapt die out. This idea is known as:
Answer:
The right approach will be "Natural selection".
Explanation:
Natural selection seems to be a mechanism that persists and reproduces populations of organisms that seem to be better suited to applications, however those that are somewhat properly equipped die away. This demonstrates that organisms that really can respond to a given climate can rise in quantities and therefore will ultimately outperform certain species that are unable to respond significantly.Apart from nitrogen and oxygen, name two other gases present in air

Explanation Worked out
Sam does an experiment in his lab. He discovers that the mass of the reactants before his
experiment is the same as the mass of the products after his experiment. What did he prove?
Answer:
The law of conservation of mass
Explanation:
In the given scenario of the experiment, Sam is proving here the law of conservation of mass.
What is law of mass conservation?The law of conservation of mass basically implies that mass can neither be created nor be destroyed in any chemical reaction.
When coal is burned, for instance, the carbon atom altered into carbon dioxide. The carbon atom changes from a solid to a gas, but its mass remains constant.
The law of conservation of mass is a fundamental physics principle. In other words, no matter how the parts are rearranged, the mass of an object or collection of objects remains constant.
The law of conservation of mass was critical to the advancement of chemistry because it helped scientists understand that substances did not vanish as a result of a reaction, but rather transformed into another substance of equal mass.
Thus, here Sam is demonstrating law of mass conservation.
