B
digestive system absorbs water and nutrients and circulatory systems carries nutrients to cells and excretory system helps eliminate waste
Answer : The reason is Osmosis.
Explanation :
Osmosis : It is a type of process in which the movement of particles occurs from its high concentration to low concentration through the selective semi-permeable membrane.
From the given image we conclude that the molecule A diffuses across the membrane but molecule B do not due to the osmosis. That means the selective semi-permeable membrane allows only molecule A through it.
Hence, the reason is Osmosis.
Answer:
An organism that eats another organism is called a consumer.
Explanation:
In food webs, consumers are characterized by not being able to produce their own nutrients, having to acquire them from the consumption of other living beings.
Consumers are found from the second level of the food web and can be primary consumers, or herbivores, and secondary, tertiary or even quaternary consumers, who are carnivores.
The other options are not correct, due to:
<em> a. Vertebrate

<em> c. Invertebrate: lack of internal skeleton and spine
</em>
<em> d. Embryo: is the product of fertilization, whose development occurs in the uterine cavity or inside an egg.</em>
2. Thymine with Adenine & Cytosine with Guanine
3. The Dna double helix must unwind near the gene which is supposed to get transcribed.
4. RNA polymerase
5. Uracil with Adenine & Cytosine with Guanine
8. Nucleotides
9. RNA polymerase
10. Dna - 2 strands MRNA - 4 strands
11. MRNA is an intermediary between the genetic info in Dna and the sequence of amino acids in proteins
