What is the molecule in this image?
Nucleic acid
A protein
A lipid
A carbohydrate

Answer:

The membrane is selectively permeable because substances do not cross it indiscriminately.

Explanation:

Nucleic acids are assembled in the 5' to 3' direction during DNA replication. DNA replication is the process of duplication of DNA molecule.

Nucleic acids are the biomolecules occurring in the chemical compounds which serve as the primary information-carrying molecules in the cells. Nucleic acids play an important role in directing the process of protein synthesis. The two main classes of nucleic acids include deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).

Nucleic acids can only be synthesized in vivo in the 5′-to-3′ direction and these can be assembled in the same direction in cell, as the polymerases which assemble various types of new strands generally rely on the energy which is produced through breaking the nucleoside triphosphate bonds to attach these new nucleoside monophosphates to the 3′-hydroxyl (−OH) group, through a phosphodiester bond.

Answer:

water will move out of the cell,energy is required

Explanation:

water moves through osmosis which is the movement of water molecules from a region of higher concentration to a region of lower concentration.

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).

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.

Answer:

the nitrogen cycle

Explanation:

Answer:

Process A is diffusion

- diffusion is the random movement of molecules from the area where there is more of them to an area where there is a few of them without the input of energy.

Process B is facilitated diffusion

- facilitated diffusion is the transport of substances across a cell membrane from an area of higher concentration to a lower concentration with the help of Transport protein

Process C is active transport

- A ctive transport is when an input of energy is required to move materials through a cell membrane .
