A life-form from another universe is found to have nucleic acid which includes six different bases - R,S,T,X,Y and Z. The percentage composition of R,S and T is always the same, and the percentage composition of X,Y and Z is always the same. Propose a reasonable hypothesis regarding the structure of the nucleic acid.
R, S, and T always have the same percentage composition, while X, Y, and Z always have the same percentage composition. Chargaff's rule is then a viable theory that can be used in this situation.
The DNA of any species of any organism must have a 1:1 stoichiometric ratio of the purine and pyrimidine nucleotides, according to Chargaff's principles. More specifically, the ratio of guanine and adenine to cytosine and thymine must be the same. This pattern is present in both the strands of the DNA.The formula comes as A + G = T + C = 1In this universe there are six base pairs R,S,T,X,Y and Z. composition of R,S and T is always same thus these can be considered the purines.The percentage composition of X,Y and Z is always the same thus these can be considered the pyrimidines.applying Chargaff's rule to these bases:R + S + T = X + Y + Z
= 1:1
Thus, the nucleic acid will contain six base pairs where bonds are formed between RX, SY and TZ.

Describe the role of the hypothalamus and the adrenal glands in bringing about changes in the blood vessels in the human skin and explain why these changes occur.
The role of the hypothalamus and the adrenal glands is The hypothalamus stimulates corticotropin-releasing hormone (CRH) that stimulates the pituitary gland to perspire adrenocorticotropin hormone (ACTH). ACTH then prompts the adrenal glands to make and release cortisol hormones into the blood.
What are the responsibilities of the adrenal glands?Adrenal glands are endocrine glands found on top of your kidneys. They produce many essential hormones, including cortisol, aldosterone and adrenaline. The adrenal hormones help control several bodily functions including metabolism, blood pressure and your body's reaction to stress.
What is the function of the hypothalamus?hypothalamus, a system deep in your brain, acts as your body's smart control coordinating center. Its main role is to keep your body in a stable state called homeostasis.
It does its job by directly influencing your autonomic nervous system or by controlling hormones.

Uranus and Neptune have comparable masses and internal compositions. Their outer atmospheres are composed of hydrogen, helium and methane, while their mantles are a mixture of water, ammonia and methane ices, and their cores are a mix of rock and ice.
The planets like Uranus and Neptune are found at outermost part of the Solar system, since they are located after the asteroid belt.All of these outer planets are much larger then the internal ones so they are also known as "ice giants". The other reason for this name is that they are very distant from the Sun, so their temperature is low.Another feature they have in ordinary is their atmosphere which is composed of gases, including methane, which is accountable for their blue color, since methane absorbs red light.However Neptune is known for very short winds and storms in its atmosphere which is accountable for its high action and changes.

Doubling the amount of water a person drinks daily.
Drinking caffeinated beverages several times a day.

Alcohol can boost GABA activity in the brain in one of two ways: either by acting on the presynaptic cell, which increases GABA release, or. It can influence the postsynaptic (i.e., signal-receiving) neuron, promoting the GABAA receptor's activation.
The brain circuits that regulate motivational processes, such as arousal, reward, and stress, are altered by chronic alcohol consumption. These modifications impact systems that use dopamine, opioid peptides, -aminobutyric acid, glutamate, and serotonin as signaling molecules as well as systems that control the brain's stress response. Frequent episodes of intoxication, obsession with alcohol, use of alcohol in spite of negative effects, and a need to seek out and use alcohol are all signs of alcoholism developing.

Aerobic exercise uses enough oxygen for oxidative phosphorylation in the mitochondria of our muscles.
Explain how the products of cellular respiration change as we push our bodies harder. How does this affect our ability to continue exercising?
Aerobic is one that uses oxygen in the process of generating energy in the muscles. This type of exercise works a large number of groups rhythmically.
What happens in aerobic respiration?
Aerobic respiration is the one that participates in the control and can be probable in three steps: analysis of glycolysis, Krebs cycle and oxidative phosphorylation. When breathing, we soon imagine the inflow of oxygen and the outflow of carbonic acid through our airways.
With aerobic cellular breathing, more and more ATP is broken down so that it generates more energy so that we can continue to perform the exercises. This energy causes cells to break down fats.

2. Why is an amniotic egg an evolutionary leap for reptiles? 1It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. 2 It allowed for many offspring to be made at the same time. 3 It allowed female reptiles to lay their eggs and leave the young to fend for themselves. 4It allowed for asexual reproduction by females only.
It allowed animals to move away from water as a requirement for reproduction and become completely terrestrial. Option 1.
Evolutionary advantage of the amniotic eggThe amniotic egg enables organisms to live their lives entirely away from water.
Prior to the evolution of the amniotic egg, the egg being laid by animals cannot survive on land. Also, the fertilization of the eggs requires water.
The amniotic egg is equipped with features that enable it to survive conditions on land. The external shell and the amniotic fluid protect the embryo from mechanical damage and dehydration. Gaseous exchange and waste excretion of the embryo are taken care of by the allantois and the chorion.

In some British hospitals as late as the 1960's flowers and plants were removed from patients rooms at night and placed at the end of the nearest hallway, then returned the next morning. This is no longer done. Can you think of a reason for this practice to have existed in the first place. (Hint: Think in terms of cellular respiration and photosynthesis, not allergies or something else.)
The reason the flowers and plants were removed from patients rooms at night was to prevent the carbon dioxide emitted from affecting the patient.
What is Photosynthesis?This is the process in which green plants manufacture their food in the presence of sunlight.
The light dependent reactions cannot occur at night due to the absence of sunlight thereby resulting in more carbon dioxide being produced during aerobic cellular respiration.
