A water molecule is
Answer:
Water is a chemical compound and polar molecule, which is liquid at standard temperature and pressure. It has the chemical formula H2O, meaning that one molecule of water is composed of two hydrogen atoms and one oxygen atom. Water is found almost everywhere on earth and is required by all known life. About 70% of the Earth's surface is covered by water. Water is known to exist, in ice form, on several other bodies in the solar system and beyond, and proof that it exists (or did exist) in liquid form anywhere besides Earth would be strong evidence of extraterrestrial life.

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.
Your answer: Here are 3 reasons that go against growing wheat this way.
1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.
2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.
3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.
If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

Tostos (2)
A. Releases a hormone if blood calcium levels get too high
B. Releases hormones to regulate the endocrine system
C. Regulates the pituitary gland
D. Releases insulin if blood sugar levels get too high
The thyroid gland secretes the thyroid hormones that releases a hormone if blood calcium levels get too high and in this way regulats the calcium level in the blood that is present in option A.
The thyroid gland plays a crucial role in regulating metabolism, which is the process by which the body converts food into energy. Metabolism is a complex process that involves various chemical reactions that take place within the body's cells. The thyroid hormones T4 and T3 are responsible for regulating many aspects of metabolism such as thyroid hormones increase BMR, which means that the body burns more calories even when one is not doing any physical activity.

Trastorno alimenticio caracterizado por una gran pérdida de peso, que el propio paciente se provoca y que puede conducir a un estado de inanición.
Answer: Anorexia nerviosa.
Explanation:
La anorexia nerviosa es un trastorno o desorden alimenticio en donde se produce un rechazo de la comida debido a un temor excesivo a subir de peso, llegando a un estado de inanición serio. Entonces, se produce un deterioro en la salud y una debilidad causada por una ingesta insuficiente de nutrientes causando una desnutrición que altera diversas funciones del organismo. Es mas común en mujeres jóvenes o adolescentes aunque se reportan casos en ambos sexos y a cualquier edad. No debe confundirse con otro trastorno llamado simplemente anorexia, que es un síntoma que se caracteriza por una falta de apetito debido a alguna causa orgánica.
Este trastorno puede ocurrir por diversas causas que vienen acompañadas por una distorsión de la imagen corporal propia, en donde la persona considera que debe perder más peso de lo que se considera saludable y normal para su edad y estatura, llegando a estados raquíticos. También hay muchos casos en donde además de una dieta extrema, se realice ejercicio de manera excesiva o que utilicen otros métodos para bajar de peso como el abuso de laxantes u otros medicamentos.
Algunos factores de riesgo para el desarrollo de la anorexia nerviosa pueden ser:

What type of RNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide
chain?
Answer:
mRNA
Explanation:
There are three types of ribonucleic acid (RNA) viz: messenger RNA, ribosomal RNA (rRNA) and transfer RNA (tRNA). These three RNA types function differently from one another. mRNA is a type of RNA that conveys genetic information that was previously stored in DNA into the ribosome for translation i.e. synthesis of amino sequence.
In other words, mRNA acts as a temporary copy of DNA's instructions and provides details on how to assemble a polypeptide chain using the amino acid sequence that arise from translating it in the ribosomes.
