Write a 2 paragraph summary about the structure of DNA from the information on the first page.
FYI the picture is attached
Answers
Answer:
DNA is made of chemical building blocks called nucleotides. These building blocks are made of three parts: a phosphate group, a sugar group and one of four types of nitrogen bases. To form a strand of DNA, nucleotides are linked into chains, with the phosphate and sugar groups alternating.
The four types of nitrogen bases found in nucleotides are: adenine (A), thymine (T), guanine (G) and cytosine (C). The order, or sequence, of these bases determines what biological instructions are contained in a strand of DNA. For example, the sequence ATCGTT might instruct for blue eyes, while ATCGCT might instruct for brown. The complete DNA instruction book, or genome, for a human contains about 3 billion bases and about 20,000 genes on 23 pairs of chromosomes.

Environmental consequences of using fossil fuels:Air contamination from petroleum products can cause corrosive downpour, eutrophication (inordinate supplements that can hurt amphibian environments by bringing down oxygen levels), harm to harvests and woodlands, and mischief to untamed life.
Water contamination: From oil slicks to deep earth drilling liquids, petroleum derivatives cause water contamination.
Thus, option B is correct.

In the picture, there is a dark moth and light moth on each tree. If all the trees are dark colored
(without lichens) like the tree on the right, which moth is more likely to survive? DS
(1 Point)
Answers
Answer:
If all the trees are dark-colored (without lichens) like the tree on the right, the moth that would most likely survive longest is the dark-colored moth.
Explanation:
This is because of natural selection (which means "A process in which individual organisms or phenotypes that possess favourable traits are more likely to survive and reproduce: the differential survival and reproduction of phenotypes.") The dark-colored moth is best adapted to its surroundings compared to the light-colored moth, and it will survive the longest (of the two) according to this definition of natural selection.

Answers
In the human body, the blood stream transports water and nutrients throughout the body, and the type of tissue that serves a similar function in plants is the vascular tissue that is in option 3.
What is the importance of vascular tissue in plants?Vascular tissue in plants serves many functions, including distributing water and nutrients throughout the plant and allowing the plant to grow and maintain its health. Through the vascular tissues, plants transport the products of photosynthesis to all parts of the plant and absorb water and nutrients from the soil.
Hence, in the human body, the blood stream transports water and nutrients throughout the body, and the type of tissue that serves a similar function in plants is the vascular tissue that is in option 3.
