The idea was that fertilizing the ocean and seas would lead to the in increase growth of phytoplankton population.
The oceanic plants do not release carbon dioxide into the air when they die because the sinks into the sea carrying with them the carbon dioxide for several centuries. This would then decrease the levels of carbon dioxide from the air as plants absorb carbon dioxide from the air during the process of photosynthesis.
If fish populations in the Antarctic were to decline, what would be the best way for the smaller toothed whales to adapt?
Question 5 options:
eat more baleen whales
eat more penguins
eat more phytoplankton
eat more leopard seals
Answer:
Beat more baleen whales
Explanation:
Smaller toothed whales are secondary
consumers of fish. If the fish population declined, the populations of leopard
seals, elephant seals, and penguins; animals which make up a large portion of
the whales' diet; would likely also decline.
To survive, the smaller toothed whales would have to eat more animals that feed
primarily on krill instead of fish, such as seals (not leopard or elephant
seals) and baleen whales.

In which interaction is the host harmed? Commensalism Competition Mutualism Parasitism
It is 100% Parasitism.
Parasitism is a relationship between two organisms were one organism, or the parasite feeds at the cost of the other organism or host. Ticks and dogs, these are two things a pet owner dreds to see. The tick is considered the parasite because it can get on to a dog and carries diseases with it. One disease is called the Rocky Mountain spotted fever, this can be harmful to the dog and can have it become very ill.

during transcription, is the original sequence maintained in the new strands? explain why or why not
During transcription, RNA polymerase synthesizes RNA complementary to DNA, maintaining sequence with modifications (e.g., T to U substitution).
1. During transcription, the original sequence of DNA is maintained in the newly synthesized RNA strands with certain modifications:
2. RNA polymerase binds to the DNA template and synthesizes a complementary RNA strand, following the rules of base pairing (A-U, G-C).
3. While the overall sequence is maintained, there are some differences:
4. Thymine (T) in DNA is replaced by uracil (U) in RNA.
5. Transcription may not cover the entire DNA sequence; only specific regions (genes) are transcribed into RNA.
6. Additionally, RNA processing, such as splicing and post-transcriptional modifications, can alter the final RNA sequence.
7. Despite these modifications, the essential information encoded in the DNA, such as the sequence of amino acids in a protein, is preserved in the newly synthesized RNA.
8. Therefore, while the exact nucleotide sequence is not identical, the fundamental genetic information is conserved throughout transcription.
Discuss the importance of oxygen to all living organisms, and describe how three different organisms—human, flatworm, and fern—obtain the oxygen they need.
Oxygen is essential for aerobic organisms, and humans, flatworms, and ferns have evolved different methods to obtain it: humans use lungs, flatworms rely on diffusion through their skin, and ferns utilize stomata on their leaves for gas exchange.
Explanation:Oxygen is crucial for the survival of all aerobic organisms as it is essential for carrying out metabolic functions. Different organisms have evolved various mechanisms for obtaining oxygen, depending on their size, shape, and habitat. Larger organisms require specialized respiratory systems due to the increased diffusion distance and the decreased ratio of surface area to volume that comes with a larger body size.
Humans obtain oxygen through their well-developed respiratory system which includes the lungs and respiratory passages. Oxygen is inhaled into the lungs, where it diffuses into the bloodstream and is then transported throughout the body.
Flatworms have a simple body plan that allows for oxygen to be obtained directly through diffusion across their skin, suitable for their small size and flattened shape.
Ferns, being plants, use their leaves to absorb oxygen from the air at night and also produce it during the daytime via photosynthesis. They have pores called stomata that open and close to regulate the intake of carbon dioxide and the release of oxygen.
Oxygen is more reactive than nitrogen.

1. Hydrochloric acid is used to produce fertilizers and dyes, to pickle and clean metal products, and as a reagent in the photographic and rubber industries. what are chemical properties of hydrochloric acid
Answer:
Hydrochloric acid reacts with zinc metal to produce hydrogen gas, zinc chloride, and heat.
Explanation:
The chemical properties of hydrochloric acid are monoprotic which can donate only one proton (H+). In water which completely dissociates to form hydrogen and chloride ions.
What is Hydrochloric Acid?Hydrochloric acid also known as muriatic acid is an aqueous solution of hydrogen chloride. It is a colorless solution with a characteristic pungent odor that is classified as a strong acid and is a component of gastric acid in the digestive tract of most animal species, including humans.
Physical properties such as the boiling and melting points, density, and pH of hydrochloric acid depend on the concentration of hydrochloric acid in water. It is colorless with a very pungent odor.
The reason hydrochloric acid dissociates into hydrogen and chloride ions is because it is a polar covalent compound and therefore ionizes when it is added to water.
Thus, the chemical properties of hydrochloric acid are monoprotic which can donate only one proton (H+). In water which completely dissociates to form hydrogen and chloride ions.

How do temperature and salinity affect deep water currents?
Differences in the density of water can also cause currents to form and move. Density is affected by temperature and salinity. Cold water or water with dissolved salts (higher salinity) is denser than warm water or water without dissolved salts (low or no salinity).

When studying heredity, what is the relationship of DNA bases and traits?
In the study of heredity, the relationship between DNA bases and traits is crucial. DNA is made up of nucleotide base pairs, which determine the sequence of genes and the expression of traits.
Explanation:In the study of heredity, the relationship between DNA bases and traits is crucial. DNA is made up of nucleotide base pairs, which are the building blocks of DNA. Different combinations of these base pairs determine the sequence of genes, which in turn determines the expression of traits. For example, different alleles of a gene coding for hair color can result in individuals having different hair colors.

Answer:

Explanation:
Dense Denise is an emergency room nurse at Hopeless Hospital. She notices that the hospital is running short on blood, so she decides to dilute the blood with water to make it last longer. Later, Dr. Dingo, the attending physician gets ready to give a patient a transplant. As a precaution, he puts a sample under the microscope, sees this image. He immediately begins angrily barking at Denise. What happened to the blood cells? A) The blood cells burst because they were placed in water, a hypotonic solution. B) The blood cells burst because they were placed in water, an isotonic solution. C) The blood cells burst because they were placed in water, a hypertonic solution. D) Denise did not dilute the blood enough, causing the cell walls to collapse onto the blood cells and make them burst.
Here, the core answer is that the blood cells burst because they were placed in water, a hypotonic solution. That is, in Option A, as the blood cells are placed in a hypotonic solution, such as pure water, the concentration of solutes outside the cells is lower than the concentration inside the cells.
What happens when the shape of a blood cell changes ?Blood cells are surrounded by a selectively permeable membrane that controls the movement of substances in and out of the cell. The movement of water across this membrane is influenced by the concentration of solutes (ions and other dissolved substances) on either side of the membrane. If the concentration of solutes is higher outside the cell than inside, water will move out of the cell in an attempt to equalize the concentration of solutes on both sides of the membrane. This can lead to cell shrinkage, known as crenation.
Hence, Here, the core answer is that the blood cells burst because they were placed in water, a hypotonic solution. That is, in Option A
