Construct an explanation for that carbon hydrates are considered as a source of energy for the human body. Justify your answer with an evidence with your own words.
Please help out I’ll mark as brainlist
Explanation: Carbohydrates are mainly composed of Oxygen, Carbon and Hydrogen. the most popular carbohydrate that is compatible with the human body is glucose which is the final result of every Carb we take in. a glucose molecule has 6 carbon atoms. during glycolysis, a single glucose molecule is broken down into two pyruvate molecules. in there, the first couple of ATP is synthesized. at later steps of the cycle, more ATP molecules are reduced.

What is a snake that eats a mouse an example of?
predation
competition
mutualism
parasitism
Answer:
Predation
Explanation:
A snake that eats a mouse an example of predation.
A snake that eats a mouse is an example of predation. Predation is an ecological interaction where one organism (the predator) kills and eats another organism (the prey). Hence option A is correct.
What is predation?Predation is an ecological interaction between two organisms in which one organism (the predator) hunts, kills, and eats another organism (the prey). It is a form of consumption where the predator obtains nutrients and energy from the prey, while the prey is typically harmed or killed in the process.
In this case, the snake is the predator and the mouse is the prey. Predation is a natural and common interaction in many ecosystems, and it can have significant effects on population dynamics and community structure.
It can help regulate prey populations, prevent overgrazing, and promote species diversity.
Predators have evolved various adaptations to catch and kill their prey, while prey has evolved various defenses to avoid being eaten, such as camouflage, warning coloration, and physical or behavioral defenses.
Hence option A Predation is correct.

Describe the genetic components of the genetic material containing two variants of each chromosome pair, one from each parent. Give an example of the inputs and outputs of mitosis.
Answer:
Human cells contain two sets of chromosomes, one set inherited from each parent. Each cell normally contains 23 pairs of chromosomes, which consist of 22 autosomes (numbered 1 through 22) and one pair of sex chromosomes (XX or XY). However, sperm and ova normally contain half as much genetic material: only one copy of each chromosome. Each chromosome contains many genes, the basic physical and functional units of heredity.
Explanation:
which type of transport would be required for the solute molecules to move against the concetration gradient?
Answer:
Active Transport
Explanation:
active transport
During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

A student observes a reaction with an enzyme in a beaker. If nothing is removed from the beaker containing the reaction, what is the only thing the student must add to start the reaction again?
A.acids
B.enzymes
C.products
D.substrates
Answer:
90% Products, 10% Acids
Explanation:
enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.
But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.
Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.

Which process must occur for a muscle to be able to relax?
A. A nerve must initiate an action potential in the muscle fiber.
B. The amount of ATP in the neuromuscular junction must increase.
C. The concentration of calcium in the myofibril must decrease.
D. Myosin and actin must attach to each other.
Answer: C. The concentration of calcium in the myofibril must decrease.
I hope this helps.
Answer:
c
Explanation:
Relaxation occurs when stimulation of the nerve stops. Calcium is then pumped back into the sarcoplasmic reticulum breaking the link between actin and myosin. Actin and myosin return to their unbound state causing the muscle to relax.
A certain sugar has no change in color when tested with Benedict’s solution. Can you tell what type of sugar it is? Explain.
Answer:
a certain sugar has no change in color when tested with benedict solution. can you tell which saccharide it is? no because it could be poly or disaccharide. what is the chemical formula for a polysaccharide molecule that contains 4 glucose molecules?
Sucrose
Sucrose (table sugar) contains two sugars (fructose and glucose) joined by their glycosidic bond in such a way as to prevent the glucose undergoing isomerization to an aldehyde, or fructose to alpha-hydroxy-ketone form. Sucrose is thus a non-reducing sugar which does not react with Benedict's reagent.
Explanation:
Sugars which give no color in Benedicts test are non-reducing sugars. Sucrose, a non reducing sugar does not undergo a color change in Benedict's test.
What is Benedict's solution?Benedict's solution is a chemical reagent containing copper sulphate pentahydrate and mixtures of sodium carbonate and sodium citrate. It is used to test the presence of reducing sugars.
A positive Benedicts test gives color change of blue to brick red precipitate whereas, non-reducing sugars does not give a positive result.
Sucrose contain fructose and glucose, they do not reduces the copper ion in Benedict's solution because there are no free aldehydes or ketones in sucrose.
Thus, sucrose does not reduce and will not give a color change in Benedict's test.

there are many contributors to malnutrition and hunger; however, one factor stands out among all others. what is the primary cause of malnutrition?
Irrespective of the fact that hunger and malnutrition has many contributors, one of the leading factors that is regarded as the primary cause of malnutrition is: poverty.
Malnutrition and hunger are two terms that describe the inability of an individual to meet his or her nutritional requirement.
Irrespective of whatever definition that is given to malnutrition and hunger, the fact still remains that such an individual suffering from malnutrition and hunger is not getting the adequate nutrition they need.
There are several factors that contribute to malnutrition and hunger, however, a leading cause that seem to be the genesis of malnutrition and hunger is poverty.
Poverty can be defined as a state of lacking the means to meet basic daily needs which includes good nutrition.
Most of the countries that are very impoverished have high percentage of their populace suffering from malnutrition and hunger.
When the means is not available to get adequate and quality food, hunger and malnutrition will always prevail against every other contributors.

An ecologist in Costa Rica wanted to determine the PGR for the country in 2018, and collected all of the data necessary to calculate the rate. She concluded that there were 34,560 births and 2,310 deaths within their population of 100,000. There were also 478 immigrants and 126 emigrants that year. What was the population growth rate for Costa Rica?
The population growht rate is 32.602 % per year. Population growth can be calculated as = (births + immigrants) - (deaths + emigrants).
In this case, population growth is equal to = (34,560 births + 478 immigrants) - (2,310 deaths + 126 emigrants) = 32,602 new individuals per year
Total (original) population: 100,000 _____ 100%
32,602 _____ X
In consequence, the population growth rate per year can be estimated by the following equation:
X = (32,602 x 100)/ 100,000 = 32.602 %
