Answer:

The energy required to break multiple hydrogen bonds causes water to have a high heat of vaporization; that is, a large amount of energy is needed to convert liquid water, where the molecules are attracted through their hydrogen bonds, to water vapor, where they are not.

Answer:

Molten rock and associated fluids. Environmental changes. Surface water. Gem formation in the Earth's mantle.

The chemical reaction is represented by a chemical equation where we use some basic elements like:

This shows that reactants are forming or giving rise to different products in the reaction.

Back to the Question:

Here a chemical reaction is taking olace, where methane is being burnt in the presence of oxygen to form the products Carbon dioxide, water and energy.

So, the arrow head is towards the CO2, H2O and energy, so they are products according to the above explanation.

Answer:

The diffusion of molecules is a process that happens in our organism and the solutes move in a single direction that is always respected based on the principles of biochemistry.

Solutes always move or diffuse from compartments of higher concentration to those of lower concentration in order to equalize the amount of solute in both compartments and therefore equalize the concentrations.

Explanation:

These processes must take place between two compartments of different concentrations divided by a selective semi-permeable membrane, that is, only the solute passes and diffuses passively or actively without dragging on water or other molecules.

This process occurs in the body in those with hyper concentration of solutes in the blood in pharmacological situations.

Answer:

Features of Enzyme Catalyzed Reactions

Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind.

Explanation:

Answer:

Sodium, Magnesium, and Sulfer are all in the same period meaning they have the same number of electron shells.

Explanation:

Periods are rows in the periodic table. The number of Valence electrons grows across the period (left to right) until reaching the electron shell's capacity.

Groups occur in columns in the periodic table and all have the same number of valence electrons, and the number of electron shells increase as you move downward on the table

Answer:

A

Explanation:

DNA and RNA are made from nucleotides, each containing a five-carbon sugar backbone, a phosphate group, and a nitrogen base.

Answer:

Community

Explanation:

The community is the compilation of the different plant and animal species population in a designated area  at a particular time that interact with each other. The different species in a community have interactions with one another based on trophic levels and the supply and provision of nutrition for survival

The ecological level above the community level is the ecosystem, which is concerned with the biotic and abiotic interactions

Beloe the community level is the population, which are the number of a particular species in a location at a given point in time.

Answer:

This is Alarm.

Explanation:

Adrenocorticotropic hormones and stress.

This the hormones secreted at the corticotrophs cells of the anterior pituitary glands.Its major function is to ensure the efficient functioning of the Adrenal gland and  body response to  stress.It is also mediate the secretion of cortisol from the cortex of the adrenal gland  into the blood stream.When it is released into the blood streams it binds to the receptors in the adrenal gland to stimulate the release of cortisol hormone.

ACTH controls  diurnal (circadian) rhythm in human.This is because it peaks in the morning and progressively reduced  towards the end of the day,with lowest concentration  during  period of sleeping.

Generally stress either by dehydration or  internal complications,leads to increase in solute potential of the blood.Stress increases the activation of ACTH from the adrenal gland while boosting the concentration of cortisol. When the stress is sensed by the brain,this causes the release of  corticotrophin-releasing hormone into the bllood.

The latter cause the discharge into the blood stream of ACTH via hypothalamic–pituitary–adrenal (HPA) axis.As this enters the blood it binds to the receptors  for the cortisol secretions in the cortex of the  adrenal gland to produce cortisol as explained earlier.Cortisol is the primary sex hormone which create the alarm.

The disadvantage when forming a fossil is a high oxygen atmosphere, which is the second option, as the high oxygen atmosphere can lead to the rapid decay of organic matter, making it less likely to be preserved.

Because oxygen is a reactive gas that can decompose organic material when exposed to high temperatures and pressures, fossils will be destroyed in such a climate, which is why fossils are more commonly found in environments with low oxygen levels, such as deep underwater sediments or anaerobic environments like swamps and bogs. One of the main factors that determines whether or not an organism will be fossilized is the speed at which it is buried after death, if an organism is buried quickly, it is less likely to be disturbed or exposed to scavengers.

Hence, the disadvantage when forming a fossil is a high oxygen atmosphere, which is the second option.

Explanation:

Nucleic acids are the main information-carrying molecules of the cell, and, by directing the process of protein synthesis, they determine the inherited characteristics of every living thing. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Answer:

D

Explanation:

The atoms in a molecule cannot be separated from each other by the means of physical force because they are bound to each other through chemical bonds. Thus, the correct option is D.

Molecules are a group of two or more similar or different atoms that form the smallest identifiable unit which can be divided into pure substances such as atoms. Molecules retain the composition and chemical properties of the substance from which it is built.

Molecules can be homogenous or heterogenous depending upon the constituent atoms. If different atoms combine to form a molecule then it is heterogenous in nature e.g., CO₂ while the molecule which is made up one type of atom is known as homogenous. Example- O₃.

Molecules have chemical bonds which are responsible for the binding of atoms, these chemical bonds can be broken by applying energy in the form of heat to the molecules.

Therefore, the correct option is D.

Answer:

Blood flow is decreased below normal due to the build of of plaque in the arteries causing an increase in blood pressure.

Explanation:

When fats, cholesterol,calcium , water  builds up on the endothelial lining of the  Coronary arteries,reducing the diameter,and therefore impeding the flow of blood,these build up is called Plaque.The diseases condition that arise  from this called atherosclerosis.

With continue build up the plaque changes in the chemical components.becomes hardened, further reducing the diameter,blood volume available and therefore oxygen supply to the targeted tissues( cardiac muscles) of the heart.This leads to Ischemic heart diseases e.g chest pain-Angina. With these strokes and other complication may follows due to cut  off in oxygen and nutrients rich blood to the tissues of the brains  for the heart.

The impedance to the blood flow,forced load on the heart to pump blood and therefore High blood pressure.This is the problem with Steve CVS.
