Explanation:

Answer:

Machines known as DNA synthesizers are used to produce short pieces of DNA, up to several hundred bases in length. These synthetic sequences can then be joined to natural sequences using DNA ligase or other enzymes that splice DNA together. A gene from one organism can be attached to the DNA of another organism.

Answer:

examining the tusks, bones, teeth, (carbon levels in tissues depends)

Explanation:

Carbon-14 can be used to date the remains of dead organisms because all living things use carbon to build tissue.

The biological age of mammoths (also known as the "age at death") is usually estimated by comparison to correlations between the biological age and the wear stages of grinding teeth in extant elephants. As tusks grow, they continually incorporate ingested strontium (Sr), and the incremental record of strontium isotope ratios (87Sr/86Sr) in tusks and teeth can be used to investigate proboscidean movements

scrutinizing the bones, teeth, and tusks (carbon levels in tissues depends)

All living things need carbon to create tissue, making carbon-14 a useful tool for dating the remains of deceased species.

Mammoths' biological age, also known as the "age at death," is typically calculated by comparing it to correlations between that age and the phases of tooth wear in living elephants.

The incremental record of strontium isotope ratios (87Sr/86Sr) in tusks and teeth can be used to study proboscidean movements as tusks continuously integrate ingested strontium (Sr).

Therefore, scrutinizing the bones, teeth, and tusks (carbon levels in tissues depends).

Answer:

Liquid ammonia is liquefied ammonia and is basic in nature. It dissolves in water to give ammonium hydroxide which ionizes to give hydroxyl ions. Therefore it turns red litmus blue and phenolphthalein solution pink.

Osmosis is also used for preserving fruits and meats, though the process is quite different for the two. In the case of fruit, osmosis is used to dehydrate it, whereas in the preservation of meat, osmosis draws salt into it, thus preventing the intrusion of bacteria.

Answer: They are the same in that most of the reproductive organs of both sexes develop from similar embryonic tissue, meaning they are homologous. Both systems have gonads (male have testes and female have ovaries) that produce gametes (testes produce sperm and ovaries produce egg or ovum) and sex organs.

Answer:

Explanation:

There are three types of ion gated channel regulated by ligand binding, change in membrane potential and distortion of the cell membrane...

So the answer is ATP Binding( ATP gated) is not a mechanism to control opening and closing of Ion channels.

ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

ATP-gated channels are membrane channel proteins that open in response to binding ATP.

These channels require energy in the form of ATP to open and thus allow the passage of ions/molecules across biological membranes.

For example, the P2X7 receptor is an ATP-gated channel that mediates apoptosis (programmed cell death) of immune cells.

In conclusion, ATP binding (ATP gated) IS NOT a mechanism to control the opening and closing of ion channels (Option a).

Skeletal muscle exhibits alternating light and dark bands called a sarcomere

Skeletal muscle is having sarcomere having myofibrils which appear dark and light in the microscope.

Only thin filaments containing actin are present in isotropic bands, anisotropic bands are the darker bands (A bands).

Repeating sarcomere sections, which are visible under the microscope as alternating dark and light bands, make up myofibrils.

When a muscle contracts or relaxes, long, fibrous protein filaments called sarcomeres glide past one another. Because of this, skeletal muscle is also known as striated muscle.

Therefore in appearance due to myofibrils composed of the sarcomere look light and dark bands in the skeletal muscle under a microscope.
