Oxygen helps organisms grow, reproduce, and turn food into energy. Humans get the oxygen they need by breathing through their nose and mouth into their lungs. Oxygen gives our cells the ability to break down food in order to get the energy we need to survive.

Answer:

Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. ... This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .

Hydrogen is used as an energy source as it is an efficient form of energy compared to the other sources, but it is expensive. Thus, option C is correct.

Hydrogen energy is the use of hydrogen gas in the production of energy that is more efficient than the other sources as it has a greater fuel conversion rate than petrol and diesel.

Ther hydrogen energy is also a disadvantage as it is expensive as it includes steam reforming and electrolysis which are costly processes and hence are not used globally.

Therefore, hydrogen energy is efficient but is an expensive method.

Four (4) spermatids result from one spermatogonium. Details about spermatogenesis can be found below.

Spermatogenesis is the process by which sperm cells are produced from the testes of a male animal.

Spermatogenesis involves series of mitotic and meiotic divisions that finally result into the haploid sperm cells.

Spermatids are haploid cells produced by meiosis of a spermatocyte that develops into a spermatozoon.

The spermatogonium divides mitotically into primary spermatocyte which then develops into secondary spermatocyte via meiosis. Each secondary spermatocyte forms 4 spermatids.

Tertiary Consumers - Organisms that obtain nutrients and energy by eating primary and secondary consumers. They are at the topmost level of the food chain.

Secondary Consumers - Organsims that prey on primary consumers for their food and energy.

Primary Consumers - Organisms that feed on primary producers, or plants for energy. They are herbivores, and make up the second trohpic level.

The tumors support their general proliferation by producing a growth element that they also respond to, this mechanism is called autocrine signalling.

Autocrine signaling means the display and secretion of an extracellular intermediate by a cell followed by the binding of that mediator to receptors on the same cell to start signal transduction.

A form of autocrine signaling is the secretion of IL-1 by macrophages.

Hypothalamus is a small part lied f the brain that is between the inferior and anterior of thalamus. This gland is linked up with the pituitary gland by the stalk-like infundibulum. The pituitary gland comprises of an anterior and posterior lobe and each love produce different hormones in response to signals from the hypothalamus.

posterior lobe contains the ends of nerve cells that is from hypothalamus. The hypothalamus transmitt the hormones directly to the posterior lobe via these nerves, and then the pituitary gland releases them.

because they were originally long period comets whose orbits were perturbed by the gravity of the giant planets and directed into the inner solarsystem

Halley's Comet is part of our solar system because it orbits around the Sun.

Halley's Comet is a periodic comet that follows a predictable orbit around the Sun and brings it close to the Earth once every 75-76 years. Halley's Comet originated from the Kuiper Belt, which is a region of the solar system containing icy objects.

When the comet approaches the Sun, the comet's ice and dust sublimate, which creates a bright coma that can be seen from Earth. The comet's nucleus is about 11 kilometers in diameter.

Halley's Comet is observed by humans for thousands of years. The regular return of comets allows scientists to study them in detail, thereby, helping us understand comets and the early solar system.

Therefore, Halley's Comet is part of our solar system because it orbits around the Sun like the other planets or objects in our solar system.

Explanation:

If a person who commits a crime leaves even the smallest speck of their blood, hair, or other organic matter, the DNA in this material can be amplified by PCR subjected to genetic analysis.

What is the use of PCR in crime scenes?

With PCR, crime scene investigators can extrade strains of DNA into quantities that may be recognized and connected to a suspect. Biologists can produce a couple of copies of character genes to look at gene function, evolution, and different topics.

PCR is a procedure wherein tens of thousands and thousands of copies of a particular collection of DNA may be made in a count number of just a few hours. This is crucial for forensic DNA samples because the DNA regularly located at crime scenes is constrained in each amount and quality.
