How much of planet Earth is covered in water?
Group of answer choices
Between 50 - 69%
Above 70%
Below 50%
Answer:
Above 70%
Explanation:
About 70% ( approximately 3/4 ) of the surface of the earth is covered with water. We can find water inside the earth in lakes, rivers, water vapor, etc. But only, about 3% of freshwater can be found on earth. Of that, only, about 0.01% can be used to drink. So, it is clear to us that, how important it is to protect water resources without polluting them.
Discuss the role played by transcription during replication.
Answer:
Explanation:
Transcription is the process by which the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA). DNA safely and stably stores genetic material in the nuclei of cells as a reference, or template. Meanwhile, mRNA is comparable to a copy from a reference book because it carries the same information as DNA but is not used for long-term storage and can freely exit the nucleus. Although the mRNA contains the same information, it is not an identical copy of the DNA segment, because its sequence is complementary to the DNA template.

Which phase of the cell cycle directly follows prophase?
OA. Interphase
OB. Metaphase
OC. Anaphase
OD. Telophase
The cell cycle directly follows prophase is metaphase.
What is Cell cycle?A cell's growth and division are accompanied by a sequence of processes known as a cell cycle. A cell spends the majority of its time in what is known as interphase, where it develops, duplicates its chromosomes, and gets ready to divide.
The cell then exits interphase, goes through mitosis, and finishes dividing. Each of the resultant cells, referred to as daughter cells, enters its own interphase to start a fresh cycle of the cell.
The procedure through which cells multiply and divide into two new cells as the cell cycle. G1, S, G2, and M are the phases of the cell cycle, respectively. Cells are getting ready to divide at the G1 stage.
Therefore, The cell cycle directly follows prophase is metaphase.

What results from the process of desalination?
Ore is extracted from the ground.
The supply of fresh water is increased.
Wastewater is handled and safely disposed of.
Steam is collected from within Earth’s crust.
The supply of fresh water is increased. Therefore, option (B) is correct.
What is desalination?Desalination is the process of removing salt and other minerals from seawater in order to make it suitable for drinking or irrigation. There are several different methods of desalination, including reverse osmosis, thermal distillation, and electrodialysis. These processes are used to produce fresh water from seawater in areas where there is a shortage of fresh water resources.
Desalination can be an effective way to increase the supply of fresh water in areas that are prone to drought or have limited access to other sources of water, but it can be expensive and energy-intensive.

What is the impact on human health as we try to stay ahead of the evolutionary process?
(Hint: Consider diagnoses of new illnesses, research and development of medicines, and biological factors like antibiotic resistance).
Staying ahead of human evolution has provided more harm than good impact on human health. According to an evolutionary perspective, several genetic variations interact with surroundings and other genes during development to affect the phenotypes of diseases.
Evolution is a set of intricate mechanisms through which populations of organisms change over time and is regarded by scientists as the fundamental, unifying notion of biology. Genetic adaptations brought about by evolution enable organisms to endure, remain healthy, and flourish.]Often sparked by war and natural disasters, public health evolved via trial and error and the expansion of scientific medical knowledge. Specifically, urbanization and social changes, as well as other aspects of the growth of community life, increased the demand for organized health protectionHence , The process of evolution has significantly impacted human health.

Two neurons are shown below. In the drawing, label an axon, a dendrite, and a nucleus as well as a synapse
A neuron may be defined as the rudimentary unit of the brain and nervous system. The nerve cells are composed of a structure of neurons that transmits and acquire signals from your brain.
What are the parts of a Neuron?Neurons have the following parts each with definite functions:
Axon: It conducts electrical impulses to other neurons. Dendrites: They transfer the received information to the soma or cell body of a neuron. Nucleus: A central part of the soma consists of a nucleus. Synapse: It transmits the nerve impulse between two successive nerve cells.The various thread-like projections are dendrites, a long thin slender structure known as Axon, while the terminal spherical structure constitutes the synapse, and the central part within the cell body or soma is known as the nucleus.

boron& molybdenum are essential nutrients classified as: a) cofactors,b) antioxidants,c) major minerals,d) trace minerals
Answer:
d) trace minerals
Explanation:
Boron (B) and molybdenum (Mo), two of the seven essential micronutrients, also known as trace elements, are required for the normal growth of most plants.
researchgatenet
Boron and molybdenum are essential nutrients classified as trace minerals. Therefore, option D is correct.
What are essential nutrients in plants?An important nutrient is one that the plants cannot produce on their own or cannot produce in sufficient levels for basic activities, hence it must be obtained from the environment in order for the plant to function normally.
Essential elements are classified into two categories on the basis of the requirements of the plant and those are macro nutrients and micro nutrients. Macro minerals contain oxygen, nitrogen, sulfur, hydrogen, magnesium, manganese, and carbon. Microminerals contain boron, molybdenum, and zinc.
Thus, boron and molybdenum are essential nutrients classified as trace minerals. Therefore, option D is correct.

During the mining process, which step immediately follows separating the mineral from the waste rock?
refining
distribution
crushing and milling
drilling and blasting asap please
Comminution
In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from their interlocked state physically by comminution.
The step that immediately follows separating the mineral from the waste rock during the mining process is crushing and milling. Therefore, the correct statement is option C.
What is crushing and milling?When the mineral gets separated from the waste rock in the form of large chunks, it further needs to be processed before it can be used. Crushing and milling break down the mineral into smaller pieces, which are easy to be processed early and refined.
Crushing uses mechanical force to break down the mineral, while milling grinds the mineral into a fine powder using heavy machinery such as crushers, ball mills, etc.
After the crushing and milling process, the mineral is more suitable for further processing, which involves additional steps such as flotation, leaching, etc. The final product formed is then distributed to the market.
Therefore, crushing and milling involve separating the mineral from the waste rock during the mining process.
