Answer:

Animals are dependent for multiple reasons.

Explanation:

The energy is transferred to animals when they eat plants. They also need it because vitamin D is given when animals get sunlight on their bodies, building strong bones and healthy marrow. The same happens when they eat vitamin D-rich plants. Hope this is helpful!

Answer:

B is true

i took the test

Oil is a renewable energy resource. It is processed to make jet fuel. Thus, the correct option is B.

Renewable energy is the energy which is derived from natural sources which are replenished at a higher rate than they are being consumed. Sunlight and wind are the two such sources of energy which are constantly being replenished from the planet. Renewable energy sources are present in plentiful amounts and are found all around us.

Jet fuels are the energy fuels which are typically made by the blending and refining of various crude oils such as petroleum distillation products including naphtha, gasoline, or kerosene in order to meet the specific military or commercial specifications required.

Therefore, the correct option is B.

Answer:

a, b, and c

Explanation:

Generally, correlation measures the strength of the relationship that exists between two variables. A positive correlation means that the two variables have the tendency to either increase or decrease together while a negative correlation means that the two variables tend to move in opposing directions, that is, as one is increasing, the other is decreasing and vice versa.

Now, the researchers find a negative correlation between the amount of weekly exercise and the number of flu symptoms in the subjects. This means that the more the exercise, the lesser the number of flu symptoms and the lesser the exercise per week, the more the flu symptoms. Hence, the assumptions that can be made directly or indirectly from the findings include

Answer:

B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.

Explanation:

There are three ways for a plant to obtain their food, photosynthesis, chemosynthesis, and heterotrophic. Photosynthesis is when the plant makes it's own food. If it can not get it's food from chemosynthesis or photosynthesis, it has to be an heterotrophic plant. The answer to the question is B. All organisms that cannot synthesize their food by means of photosynthesis or chemosynthesis are heterotrophic.

To a 1st Grader:  

Carbon is the magic element that is the basis of life on Earth. All living things contain carbon. Animals breathe it out, and plants breathe it in. Plants, people and animals depend on each other.

The carbon cycle is a process where carbon dioxide travels from the atmosphere into living organisms and the Earth, then back into the atmosphere. Plants take carbon dioxide from the air along with water and photosynthesis from the sun and use it to make food.

Explanation:

The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.  To a first grader is different because they wouldn't understand what half of these words mean lol.

The carbon cycle is the biogeochemical cycle that exchanges carbon between the Earth's biosphere, parallel layers, geosphere, hydrosphere, and atmosphere.

The carbon cycle is nature's method of recycling carbon atoms, which travel from the atmosphere into organisms on Earth and then back into the atmosphere.

The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, atmosphere, and living organisms.

The carbon cycle is critical to the survival of life on Earth. Nature has a tendency to maintain carbon levels in balance.

This means that the amount of carbon naturally released from reservoirs equals the amount naturally absorbed by reservoirs. Maintaining this carbon balance ensures that the planet remains habitable for life.

Thus, by regulating the rate of carbon dioxide in the atmosphere, the carbon cycle plays an important role in regulating Earth's global temperature and climate.

c. OFF

d. ON

Explanation:

Allosteric regulation is a process by which a particular molecule activates or inhibits an enzyme, by binding to a site different from the active site of the enzyme. Allolactose is a disaccharide that binds to the allosteric site of the lac repressor protein, triggering a conformational change in the protein that prevents the binding of this repressor to DNA. Moreover, RNA polymerase (RNA pol) is an enzyme required for the process of transcription, and therefore when this enzyme cannot bind to operon genes the lac operon is being turned OFF.  Finally, the lac operator is a nucleotide sequence where RNA pol binds, and the lac repressor binds to the lac operator in order to block the transcription of the lac operon.

Explanation:

1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.

2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.

Answer:

true

Explanation:

Answer:

represent a single species

Explanation:

According to the biological species concept, a species can be defined as a group of organisms that can potentially interbreed (i.e., mate) in order to produce viable and fertile offspring. Based on this concept, the cohesion forces that maintain the integrity of the species as a single group are 1-interbreeding between its members and 2-reproductive isolation mechanisms that prevent successful mating between organisms from different species. In this case, both bird populations represent the same species because when individuals of these populations are brought together they can interbreed to produce viable and fertile offspring.

Eukarya is not the correct answer because they have organelles and a nucleus. Archaea is not the correct answer because they have organelles and a nucleus.

Microbes known as bacteria have simpler cell structures than many other types of creatures. One DNA loop serves as their command center and houses all of their genetic data. Instead of a nucleus, some bacteria have an additional ring of genetic material called a plasmid.

Genes that offer the bacterium a competitive edge over other bacteria are frequently found in the plasmid. For instance, it might have a gene making the bacterium immune to a specific antibiotic.

Therefore, Bacteria is the correct answer because it lacks organelles or a nucleus. Protista is not the correct answer because they have organelles and a nucleus.

Answer: The nearby nerve that can be affected by this tumour is the FACIAL NERVE.

Explanation:

As stated in the question, the acoustic neuroma is a tumor that arises from the vestibular portion of the vestibulocochlear nerve which is the VIII ( 8th) cranial nerve.

VESTIBULOCOCHLEAR NERVE: These nerves are composed of two distinct sets of fibres, vestibular nerves and cochlear nerves.

The vestibular nerves arise from the semicircular canals of the inner ear and convey impulses to the cerebellum. They are associated with the maintenance of posture and balance. The cochlear nerves originate in the spiral organ in the inner ear and convey impulses to the hearing areas in the cerebral cortex where sound is perceived.

The Facial nerve, also called the 7th cranial nerve, which are the motor fibres that supply the muscles of facial expression. It lies adjacent to the vestibulocochlear nerve as they pass through the internal auditory canal which is located at the petrous part of the temporal bone. As the tumor grows, the facial nerve would be affected because it's the closest nerve to the VESTIBULOCOCHLEAR nerve..
