- Description of the process used to study this population or phenomena, including selection criteria, controls, and testing instruments (such as surveys).
Why is it that dominant diseases are not as common as recessive ones?
Answer:
Mainly because if a disorder is dominant, then it will be manifested by all who have the gene. If the disorder is severe, then it will reduce the chances of the individual surviving to grow up and reproduce (unless the disorder only manifests symptoms in later life). If they do reproduce, then 50% of their offspring will inherit the gene, and be at a similar disadvantage in reproduction. Thus, there is likely to be selection against the gene. By contrast, a recessive disorder is only manifested if both parents pass on the abnormal gene, and an individual with one gene for the disorder is usually at no disadvantage. Thus, there is much less selection against abnormal recessive disorders.

What stage of cell respiration is being shown above?
The stage of cell respiration that is being shown above is oxidative phosphorylation. During this stage, the transport of electrons is coupled to the generation of an electrochemical gradient.
Cellular respiration can be defined as a series of metabolic reactions by which aerobic cells generate energy in the form of ATP.
Cellular respiration has three main stages: glycolysis, the Krebs cycle and oxidative phosphorylation.
During oxidative phosphorylation, the transport of electrons across the mitochondrial membrane is coupled to the generation of an electrochemical gradient, which is then used to generate ATP by an ATP synthase as shown in the figure.

write types of cellular respiration and their function?
Answer:
There are 2 types of cellular respiration i)Aerobic respiration
ii)Anaerobic respiration
Explanation:
i)Aerobic respiration: is the chemical reactions in the cells that use oxygen to break down food molecules to release energy. Its complete oxidation process that releases more energy (2830 $ J). The word equation of aerobic respiration is:-
glucose + oxygen------> carbon dioxide + water + energy.
ii) Anaerobic respiration: is the chemical reactions in cells that break down food to release energy without using oxygen. Its partial (incomplete) oxidation process that release a few energy (188 $ J) The word equation of anaerobic respiration in human muscles:-
glucose-----> lactic acid
The word equation of anaerobic respiration in yeast:-
glucose yeast alcohol + carbon dioxide

what is sugar converted into if your body does not metabolize it
Answer: It's starts burning body fat.
Explanation:
Imagine that the climate in your region became extremely arid, and freshwater became a scarce and precious resource. Wasteful uses of water, such as watering lawns and filling swimming pools, would be strictly outlawed, and water from the municipal water supply would cost 100 times what it does now. Discuss how you would adapt to that situation.
I would adapt to such situation by ensuring that physical activities are
reduced , use of water is adjusted and recycling is maximized.
Water is a n important component of life as we need water for various
activities such as drinking, cooking, washing etc. Scarcity of water can result
to unhygienic conditions and dehydration which could result in death.
it is best to ensure physical activities are reduced to prevent dehydration
through sweating. The wastage of water should be reduced to the barest
minimum through use adjustment and recycling.

Give reasons :
a) Nylon clothes should not be worn in the kitchen.
b) Cotton fibre is used to make bath towels.
c) Umbrellas and raincoats are made from synthetic fibres
Answer:
a) It is dangerous to wear nylon clothes while cooking because it is a synthetic cloth and they catch fire easily also they can stick on our body which is very painful.
b) Cotton is a natural product. And unlike synthetic fibres, it is more absorbent. The towel hence has high absorbency.
c) Nylon and polyester are two fabrics most commonly used in raincoats and umbrellas. They are not absorbent the way natural fibers are. They naturally resist waterlogging, and can be made waterproof.

The individual blades are called leaflets. The leaflets are also referred to as
foliole.
The leaflets is referred to as the individual leaf and is usually not attached
directly to the main stem of the plants.
A simple leaf has only one blade while a compound leaf has two or more
blades which are divided into parts which we call leaflets. Leaflets are
usually in groups in plants and can be plucked individually from the

What Is Chemogeny ( Chemical Evolution ) ? And Explain The Steps Of Chemogeny [Both Answer In Simple Word/ Simple Answer Which Is Easy To Concept Or Read]
Answer:
Chemogeny may be a theory of chemical evolution that depends on the chemical reactions and formation of drugs on the bases of chemical reactions. This theory says that “Life occurs as a results of evolution of inorganic matter”.
In the 1920's Scientists Oparin and Haldane, developed this hypothesis of the chemical origin of life from the primitive atmosphere of the world having matter like methane, ammonia and water. there have been very low concentrations of oxygen thanks to the presence of high temperatures like 5000-60000C. So, these conditions weren't suitable for the free existence of organic compounds, so reactions started happening .
Under conditions like high sunlight and warmth , inorganic matter gets converted to inorganic compounds. And this might end in the storage of organic compounds, which gets more and more concentrated with the passage of many years.
These compounds interact with one another and end in “life”.
So, chemogeny is that the process of chemical evolution of earth and formation of life from pre-existing matter with the assistance of chemical reactions.

Answer:
Fourth option
Explanation:
ATP - Adenosine Triphosphate (3Ps), ADP - Adenosine Diphosphate (2Ps). ATP breaks down into ADP because it loses a Phosphate Anion in whatever process that the ATP is becoming ADP.
In the image provided, fourth image shows how ATP breaks down into ADP. Option D is the correct answer.
ATP (adenosine triphosphate) is a molecule that stores and provides energy for cellular processes. When ATP is used, it undergoes a process called hydrolysis, where a water molecule is used to break a high-energy phosphate bond in ATP. Option D is the correct answer.
During this hydrolysis process, one of the phosphate groups in ATP is cleaved off, resulting in the formation of ADP (adenosine diphosphate) and an inorganic phosphate (Pi). The energy stored in the phosphate bond is released, making it available for cellular functions. The breakdown of ATP into ADP allows the released energy to be utilized by cells for various activities, such as muscle contraction, active transport, and synthesis of molecules.
