Answer:

A control variable is the element that is constant. it does not change throughout the experiment as it helps researchers understand the effect of what's being tested by comparing it to the control variable.

Explanation:

a control group does not. They should be identical in all other ways.

Answer:

A

Explanation:

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

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:

Testing Platismatia glauca could help scientists understand which pollutants have the largest effect on lichen populations. It also may help scientists understand the current pollutant levels in the atmosphere compared to the population of lichens on the trees. This information can help them more accurately predict population changes over 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.

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.

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.

Answer:

Science can not solve all of our problems. While scientific understanding can help battle things like disease, hunger, and poverty when applied properly, it does not do so completely and automatically. Furthermore, there are many areas of life where science can have little impact.

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:

By phylogenetic analyses  

Explanation:

The target of rapamycin (TOR) is a major regulator of growth only found in eukaryotic organisms. The TOR pathway is known to regulate critical cellular processes including, among others, cell growth. The TOR protein is a kinase capable of activating translation by phosphorylation of the ribosomal S6 kinase (S6K) and the eukaryotic translation initiation factor 4E binding protein (4E-BP). In this regard, phylogenetic studies have shown that this pathway involves duplication events of ancestral kinases, as well as sub-functionalization of the S6K kinase.

Answer:

No it is not a scientific theory.

Explanation:

An explanation of any aspect of the natural phenomenon of the world that can be tested several times and well supported by the evidence, and follows the scientific method. Furthermore known as scientific theory.

Presently, a logical hypothesis must meet a few rules, and one of those is that it must be upheld by a few (and free) strands of proof.  

For this situation, we have just one hypothesis, that bulldogs are great pet and Meatball is great among bulldogs, and it isn't sufficient, at that point it can not be a scientific theory.

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.

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.
