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.

Answer:

Option C. Competition happens because resources are limited.

Explanation:

When resources are limited in an ecosystem, the species compete with each other to come out as best among all.

As per the theory of natural selection, Darwin proposed that it is always the fittest of all that survive. By fittest he means the ones who are capable to compete and come out as the strongest among all to survive in a given ecosystem.

For Example - Male compete among themselves to attract the female. This is known as sexual selection.

Hence, option C is correct.

Answer:

A. mutualism: a relationship in which both species benefit

B. commensalism: a relationship in which one species benefits and  the other species is neither helped nor harmed

C. parasitism: involves one organism living on or inside  

another organism and harming it.

Explanation:

The Moon's core is thought to have formed from a giant impact between Earth and a Mars-sized object. This event fragmented and mixed materials from both bodies, with the less dense splatter forming the Moon's smaller, metallic core composed mostly of iron, sulfur, and nickel.

According to this hypothesis, Earth was struck obliquely by an object roughly the size of Mars, sometimes referred to as Theia. This collision led to a violent mixing and scattering of material from both Earth and Theia, with the lower-density material coalescing to form the Moon. As a result, the Earth retained a higher density, with a thicker core, while the Moon developed a distinct crust, mantle, and a smaller metallic core mostly composed of iron, with some sulfur and nickel.

The Moon's core is estimated to be 600 to 800 kilometers in diameter, significantly smaller compared to Earth's. This hypothesis is supported by evidence including the moon rock samples gathered by astronauts, data from the GRAIL spacecraft, and studies conducted using seismometers during the Apollo missions. These findings suggest that the Moon's interior lacks a large metal core, has a crust depleted of water and volatiles, and shares similar oxygen isotope abundances with Earth, which supports the idea that it is made primarily of terrestrial mantle material.

Answer:

All of these are included in the uniformitarian theories:

1) The Earth's crust has been formed by floods and materials derived from that.

2) The Earth's crust has been formed by current slow processes.

3) Erosion and deposition are currently very slow, but with the time, it affects in a huge way the environment.

4) Major catastrophic processes are possible. They are violent and sudden, and that's how they affect so much the planet.

A type of biotechnology that would a dairy farmer use to mate the cows at his farm with genetically superior bulls to produce offspring that give high-quality milk is, that artificial selection because offspring with desirable traits are produced.

Biotechnology may be defined as a group of technologies that deal with biological systems, living organisms, or parts of this to develop or create different products.

Human interference always leads to the production of desirable traits. This process is known as artificial selection.

This artificial selection always favors human needs. It is faster than natural selection and allows humans to develop organisms to their needs.

Therefore, the above example represents artificial selection because offspring with desirable traits are produced.

Final answer:

Erwin Chargaff discovered the base pairing rules critical for DNA structure, which was confirmed by Watson and Crick through their double helix model, integrating Chargaff's rules with X-ray diffraction data.

Explanation:

Part A: Erwin Chargaff's major contribution to our understanding of DNA structure lies in his discovery of specific pairing rules, known as Chargaff's rules. He observed that in DNA, the amount of adenine (A) always equals the amount of thymine (T), and the amount of guanine (G) always equals the amount of cytosine (C). This finding was critical for deciphering the double helical structure of DNA.

Part B: James Watson and Francis Crick's research confirmed Chargaff's conclusions by incorporating them into the development of the DNA model. Utilizing the principle that A pairs with T and G pairs with C, alongside X-ray diffraction data from Rosalind Franklin, they proposed a double helix structure. In this structure, each strand of DNA is composed of a long chain of nucleotide pairs, with hydrogen bonds between A and T and between G and C, explaining Chargaff's observations and providing a physical mechanism for DNA replication.

Answer:

The answer is D. They break rocks and transport them to new locations.

Explanation:

Weathering is the physical process in which a breakdown or breakage occurs in the rock, but without affecting its chemical or mineralogical composition, while the erosion of the rocks is the process that refers to the movement or transport of the material, in contrast to the alteration and disintegration of the rocks. It is one of the main factors in the rock cycle.

The Answer Is 27% . . . . . . . . . . . . .  The dots are so I can post the answer, because without a long reply I can't answer.

Answer:

27% .  

Explanation:

A (adenine) pairs with T (thymine) and has the same percentage. C (cytosine) pairs with G (guanine) and they both have the same percentage.  In this case, the percentage of T (thymine) is 23%.  So A (adenine) will also have 23%. This leaves the remaining percentage at 54% (100-46).  So G and C will have 27% each (totaling 54%).

Marcia is diagnosed with hypermetabolism.  One pathological cause of hypermetabolism is thyroid disorder (hyperthyroidism). It could also be caused by injury or infection in the body. There is no single treatment for the disorder since it is merely a symptom of an underlying problem. It could be managed by nutritional support coupled with pharmacological treatment such as diuretics and regular insulin.

Answer:

She is diagnosed with hypermetabolism.

Explanation:

Hypermetabolism is metabolism at an excessive or increased rate and it is characterized by the abnormal increase in basal metabolic rate. It can signal the issues like hyperthyroidism. It occurs generally after significant injury to the body and the most common causes in the institutions and hospitals are burns, sepsis, traumas, infections surgery, bone marrow transplants etc. Its cause and location can be detected by PET scan. The symptoms includes anemia, sudden weight loss, fatigue, elevated heart rate, excessive sweating etc. It is itself a symptom and not an independent disease, treatment firstly requires attention to the underlying disease. The symptoms will subside, once the underlying cause is remedied.

Answer:

mitochondria

Explanation:

The correct answer is option c) Vacuole because it is common in plant cells but rare in animal cells.

Vacuoles are membrane-bound organelles found in plant cells, as well as some fungal and protist cells. They are large, fluid-filled sacs that perform various functions, including storage of water, nutrients, and waste products, maintaining turgor pressure, and supporting the structure of the cell.

While animal cells may contain small vacuole-like structures called vesicles, they typically lack the large, central vacuole characteristic of plant cells. Therefore, vacuoles are much more abundant and prominent in plant cells compared to animal cells.

The incorrect options are:

a) ribosome: Ribosomes are present in both plant and animal cells. They are responsible for protein synthesis and are essential organelles found in all types of cells.

b) mitochondria: Mitochondria are found in both plant and animal cells. They are responsible for cellular respiration, producing energy in the form of ATP. While there may be some structural and functional differences between plant and animal mitochondria, they are present in both types of cells.

d) lysosome: Lysosomes are membrane-bound organelles containing enzymes responsible for intracellular digestion and waste removal. While lysosomes are more prevalent in animal cells, they are also found in some specialized plant cells, particularly those involved in defense and recycling processes. Therefore, while lysosomes may be rarer in plant cells compared to animal cells, they are not entirely absent.

The correct question is :

Which structure is common in plant cells but rare in animal cells?

a) ribosome

b) mitochondrion
c) vacuole
d) lysosome
