Answer: 3. adenine (A, green), thymine (T, red), cytosine (C, orange), and guanine (G, blue). 4. adenine (A), cytosine (C), and guanine (G) — are also found in DNA. 5. A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T). 6. food crops like soy and corn that have been genetically modified for pest and herbicide resistance. These crops are widely known as “GMOs” (genetically modified organisms). 7. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine. brainliest?
Explanation:
Answer:
the plasma membrane is a bilayer of lipid molecules with protein molecules embedded in it.
Explanation:
Answer:the condition is recessive, since the probability of appearing is 1/4.
Explanation:
Based on the information above,most of the children are dark skinned showing the dark skinned pigmentation being more dominant,thus the allele for albinism is recessive.
Q1. The answer is <span>c. a mechanism of evolution.
</span>
Natural selection is the differences in survival and reproduction as the consequence of differences in phenotypes. According to Darwin's theory of evolution, natural selection is the only factor that affects a frequency of different variations and it is the only mechanism of evolution.
Q2. The answer is c. interactions between individuals.
Organisms interact with other organisms or abiotic factors in some system. The interaction <span>between individuals affects their regular distribution. For example, if two groups are in competition for resources, to maximize resource utilization, they will probably live in different areas or will defend territory. Also, some symbiotic organisms are expect to be distributed similarly.</span>
