Answer:
chloroplast: makes food for plant cells, photosynthesis
mitochondria:produces energy the cell needs to carry out its functions; release energy
vacuole: stores food, water, and waste
lysosome: found mainly in animal cells, digests old cell parts
endoplasmic reticulum: carries proteins and other materials from one part of the cell to the other
cytoplasm: gel -like fluid where the organelles are found
nucleolus: makes ribosomes, center of the nucleus
ribosome: makes proteins
cell membrane:controls
Explanation:
I'm pretty sure the answer is D based on the info above,and because its the only one that has the correct information about the cell parts
hope its correct
Answer:
-blood type a
-blood type b
-SOMETIMES type o but very rarely.
Explanation:
Each biological parent donates one of their two ABO alleles to their child. A mother who is blood type O can only pass an O allele to her son or daughter. A father who is blood type AB could pass either an A or a B allele to his son or daughter. While a child could have the same blood type as one of his/her parents, it doesn't always happen that way. For example, parents with AB and O blood types can either have children with blood type A or blood type B.
The answer for this question is C, I just did my final for Biology and got a good score in it.
Hope it helps!
Answer:
With respect to the composition of DNA, in an analysis it can be found that the proportions of nucleotides are A + C = G + T (option a).
Explanation:
The proportion of nucleotides in a DNA molecule can be established according to the sequence of these nucleotides on both complementary strands, since the purinic bases of one strand are complemented by the pyrimidinic bases of another:
- <em>Adenine is complemented with Thymine A=T</em>
- <em>Guanine is complemented with Cytosine G=C</em>
From this we can deduce that in a DNA molecule with two chains there will be the same amount of adenine and thymine, as well as the same number of guanine with respect to cytosine, so:
<em> A + C = G + T</em>
An example of this would be a known DNA molecule (hypothetical), with 5 molecules of Adenine and 7 molecules of Guanine. In this case there are 5 Thymines, complementary with Adenine, and 7 Cytosines like Guanine:
<em> A + C = G + T</em>
<em> 5 + 7 = 7 + 5</em>
