Answer:
Sexual reproduction involves two parents and the joining of male and female gametes during fertilisation. The offspring inherit a mixture of genes from both parents, so are different to each other and their parents. In asexual reproduction there is only one parent. The offspring are clones of the parent and each other.
I would say it's A because it sounds like the most important one.
Answer:
It takes Earth longer to revolve around the sun than to rotate on its axis.
Explanation:
The vocabulary can be tricky in this question. It is important to remember that the term revolution refers to something moving around a fixed point. In this case, the earth is the object revolving around sun which is the fixed point in the frame of reference.
Now, the earth rotates at a constant speed around its axis. This is what causes the day/night cycle. The earth itself is spinning, therefore we use the term rotate.
The correct answer is A - chlorophyll.
It is a green pigment found in the chloroplasts of green plants. Chloroplasts are mostly found in the leaves of green plants and also in some algae.
Plants use chlorophyll to trap light energy from the sun. Without the light energy, plants cannot be able to carry out the process of photosynthesis, which converts water and carbon dioxide into starch that plants use for food.
Photosynthesis also releases oxygen which is vital for animal life.
Answer:
A desirable intake of dietary fiber is 20-35 grams daily, according to the American Dietetic Association.
Explanation:
Dietary fiber has always been a part of a healthy, balanced eating lifestyle. Fiber has 2 types, soluble and insoluble. Soluble fiber is a <u>gelatin-like</u> substance when combined with water and when ingested, <u>can help slow the travel of food in the gut, making you feel</u> <em>"full."</em> Insoluble fiber or roughage is the <u>bulk-forming type</u>. It <u>holds water</u> in its structure, helping <u>regulate the bowel movements.</u>
Fiber, being a <u>complex carbohydrate</u>, can help <u>lessen the risk of an increase of bad cholesterol and blood sugar</u>. Examples of fiber-rich foods are whole grain products, barley, oats, grapes, etc.
