An organic compound is a compund in which Carbon is a component of that compound.
Methane (CH4) is made up of Hydrogen & Carbon
As it has Carbon , its an organic compound.
Glucose (C6 H12 O6) is made up of Carbon , Hydrogen & Oxygen. As it has Carbon , its an organic compound.
DNA (Deoxyribonucleic Acid) has 5-carbon-sugar as a component . It too also has Carbon , so its an organic compound.
But NaCl (Sodium Chloride) is made up of Na(Sodium) & Cl(Chlorine) . As it doesn't have Carbon as its component , its not an organic compound . Hence itz INORGANIC.

Hope it helpedIs a vesicle found in an animal or plant cell. or both?
Answers
Answer:
Both, although they're less common in plant cells.
Both plant and animal cell have vesicle.
what are the difference between animal cell and plant cell?Plant cell have cell wall and other cell organelles while animal cell do not have cell wall but other organelles are present, has fixed-size and shape due to presence of rigid cell wall while animal cell have irregular size and shape.
Plant cell has rigid cell wall and plasma membrane while animal cell has flexible and thin plasma membrane for this reason animal cell can change their shape.
In plant cell Plastids like chloroplast, chromoplast, leucoplast and nucleus is present on one side where as plastid are absent in animal cell and nucleus is present in the central region in case of animal cell.
Plant cell can do photosynthesis and make their own food, so they are phototrophic where as animal cell do not have cell wall.

Micronutrients
- Calcium
- Vitamins
- Zinc
Explanation:
Got it right on my test. Have a good day!
Carbohydrates, proteins, and fats are the macronutrients, whereas vitamins, calcium, and zinc are the micronutrients.
What are macronutrients?Macronutrients and micronutrients are two very essential nutrients that are required for the growth and development of the body. Macronutrients are nutrients required in large quantities in the body for its growth and development, and to perform various other body functions. Carbohydrates, proteins, and fats are the three main macronutrients found.
Carbohydrates are building blocks of monosaccharides and provide energy to the body whereas proteins are building blocks of amino acids and are required to build and repair tissues in the body. Fats are also the building blocks of fatty acids and are important for protecting organs and providing energy too.
Micronutrients, on the other hand, are nutrients required in smaller amounts, and are essential part of the body. Micronutrients include vitamins and minerals such as calcium, iron, and zinc.
Therefore, carbohydrates, proteins, and fats are the macronutrients, whereas vitamins, calcium, and zinc are the micronutrients.

How can a female inherit red-green color blindness?(1 point) Her mother is a carrier, and her father has the condition. Her mother is not a carrier, and her father has the condition. Females cannot inherit red-green color blindness. Her mother is a carrier, and her father does not have the condition.
Answers
Answer:
The correct answer is - Her mother is a carrier, and her father has the condition.
Explanation:
Colorblindness is a sex linked recessive disease that is passed from the parent to the offspring through X chromosome that have recessive gene of the disease. It is rare in the females as the very low chances of the females to inherit two copies of disease gene allele. But as only one allele is present in males of X chromosome and if there is disease copy he will be color blind.
To get a colorblind female the girl child must get two copies of these allele that has recessive X chromosome one from her carrier mother and other from her conditioned father. Check image for punnet.
Thus, the correct answer is - Her mother is a carrier, and her father has the condition.

Answers
Answer:
Explanation:
homeostasis
For a plant sunlight is an example of ; ( C ) homeostasis
Plants require the light to carryout photosynthesis for proper growth and production of its food therefore insufficient sunlight will affect the growth and development of a plant. also some plants grow towards a light source ( phototropism ). to maintain its internal system.
Since the sunlight is not found within the plant but it has a direct effect on the growth and development of the plant, it is an example of a homeostasis while reproduction takes place within the plants
Hence we can conclude that for a plant sunlight is an example of ; ( C ) homeostasis
