quester [9]3 years ago
8 0

Answer:

The answer is D) It will allow scientists to make personalized medicine.

Explanation:

I used the context of the article where they stated "So for years, scientists have been trying to use cloning techniques to make embryonic stem cells that are essentially a genetic match for patients. The idea is that such a close match would prevent their bodies from rejecting the cells."

Answer:

A . proteins can take a variety of shapes, and nucleic acids tend to form linear chains

Explanation:

Proteins are consist of 50 and 2000 amino acid long and can take variety of shapes in living organisms. Two types of proteins that found in living cells are globular proteins and fibrous proteins and they have different shapes. Example of  globular protein is hemoglobin and fibrous proteins are hair and nails, and collagen.

Nucleic acids  tend to form linear chains from the monomers called nucleotides. Nucleotides have three components:  nitrogenous base. phosphate group, and pentose sugar (5-carbon sugar) that together forms a definite linear shape. It is found in DNA of living organisms.

Hence, the correct option is "A . proteins can take a variety of shapes, and nucleic acids tend to form linear chains".

PLEASE HELP!! 50 POINTS!!
Natalka [10]

Answer: 1. A living organism that feeds on organic matter, typically having specialized sense organs and nervous system and able to respond rapidly to stimuli.

2. “Animals need a lot of energy, and moving at all doesn't really jive well with photosynthesis,” says Agapakis. “If you imagine a person who had to get all of their energy from the sun, they'd have to be very still. Then, they'd need a high surface area, with leafy protrusions.

3. 3 Incredible Photosynthetic Animals (So you can chose, and thers many more!)

Sea Slug - Elysia chlorotica. The first of these amazing photosynthetic animals is a sea slug, which effectively steals genes from the algae that makes up its diet.

Spotted Salamander - Ambystoma maculatum. Ironically, the spotted salamander is not a new species for researchers, and it has long been known that the animal's embryos share a symbiotic relationship with photosynthetic algae. The color usually indicates the presence of chlorophyll, which is the light-absorbing green pigment that makes photosynthesis possible.

4. ...

5. The Spotted Salamander is born with the ability to use photosynthesis, while the Sea slug develops it over time.

6. As larvae, spotted salamanders eat insects, small crustaceans, and other aquatic invertebrates. Adults have a sticky tongue to catch earthworms, snails, spiders, centipedes, and other invertebrates they find on the forest floor, while Sea Slugs eat plankton, algae, and jellyfish that are all prey of these animals. Some of these animals are herbivores eating algae and other plant life off rocks.
