Answer:
Food webs either start with producers on<u><em> land </em></u>or with producers in <u><em>water</em></u>.
Explanation:
A food chain or a food web will always start with a producer and always end with a type of consumer. This is because producers are organisms which have the ability to make their own food. They are mostly plants or other producers like algae. Both aquatic and land food chains or food webs will start with a producer. An aquatic food web will generally start with a producer present in water. A land food web will mostly start with a producer from the land.
The answer that best fits the blank is RENDERS CILIA IMMOBILE. What happens when the left-right asymmetries in humans are reversed would lead to a genetic condition that renders cilia immobile. This is based on the role of the ciliated cells in the body that has an important impact in one's biological development.
Answer:
A sugar called deoxyribose.
Explanation:
DNA is made up of molecules called "nucleotides". These are:
- A phosphate group
- A pentose sugar [deoxyribose]
- A nitrogen-containing base [adenine, thymine, guanine and cytosine]
Thus the first option is the right answer.
Reasons why the other options are wrong:
"A plasma called haemoglobin" is wrong as plasma and haemoglobin are related to the blood.
"A chemical called nucleic acid" is wrong as it is not what DNA's made up of. DNA and RNA are nucleic acids themselves.
"An acid called chlorophyll" is wrong as chlorophyll is related to plants.
True because the sun is made from all sorts of energy
An opaque object is any object that is not transparent (allowing all light to pass through it), or translucent (allowing some light to pass through it.) Knowing this we can auto-matically dismiss option D),B), and C) because these all let some form of light through them so our answer would then be A) because light does not pass through wood like it would the others.
