Answer:
<em>The correct option is C) Both cloning and gene therapy are types of biotechnology.</em>
Explanation:
Gene therapy is a method in which scientists try to treat a disease by inserting a functional gene into an organism. This gene might be able to cure the disease instead of using drugs or surgery for treatment. Hence, gene therapy uses the techniques of biotechnology.
Cloning can be described as a type of biotechnology in which identical copies of a gene, tissue, organ or organism might be produces.
Answer:
The proportion of oxygen went up because of photosynthesis by plants. The proportion of carbon dioxide went down because: it was locked up in sedimentary rocks (such as limestone) and in fossil fuels. it was absorbed by plants for photosynthesis.
Explanation:
Adult tigers look very different from a fertilized tiger egg cell. A fertilized tiger egg cell is only a zygote. As it grows it developes stem cells that create seperate tissues. These tissues grow into organs and organ systems that form a body.
Answer:
Substances
0 (most acidic) Hydrochloric acid (HCl)
1 Stomach acid
2 Lemon juice
3 Cola, beer, vinegar.
Examples of alkaline are:sodium hydroxide, potassium hydroxide, calcium hydroxide, magnesium hydroxide etc
Specific chemicals are bound by carrier proteins and transferred on one side of the membrane. The conformational changes they go through next enable the molecule to cross the membrane and exit on the other side.
How carrier protein facilitate the diffusion?
When a molecule diffuses, it usually moves from a high concentration location to a low concentration area until the concentration is the same everywhere in the space.
Contrary to channel proteins, another form of membrane transport protein that is less selective in the molecules it transports, carriers are proteins that move a particular material through intracellular compartments, into the extracellular fluid, or across cells. Carrier proteins are found in lipid bilayer cell structures such cell membranes, mitochondria, and chloroplasts, just like other membrane transport proteins.
Therefore, carrier proteins can facilitate the diffusion of glucose or other substances into the cell.
