A cell that is dividing and making a clone of itself needs to have its DNA replicated without mistakes otherwise these mistakes ( mutations) can be deadly to its offspring.

Answer:

-To prevent mutations and keeping organisms in a healthy state.

Explanation:

DNA replication involves synthesis of daughter DNA molecules by using parent DNA as template. The cells have many methods to proceed error free replication, thus, DNA replication shows a highly accurate process.

It is because if one or more wrong nucleotide gets inserted into daughter DNA strand during replication, which does not get repaired, it will be lead to mutation in daughter cell. This mutation will pass to all progeny cells and can cause lethal consequences, such as development of cancer.

Thus, DNA replication without any mistake is important to prevent mutations and keeping organisms in a stable healthy state.

How are fungi and protists similar to plants and animals in the ecosystem?

JulijaS [17]

Explanation:

Since plants and fungi are both derived from protists, they share similar cell structures. Unlike animal cells, both plant and fungal cells are enclosed by a cell wall. ... They both also have organelles, including mitochondria, endoplasmic reticula and Golgi apparatuses, inside their cells.

torisob [31]

Hi there! This question is a bit confusing.

Primary cells more of have one "star" quality; they are not rechargable. Think of them like a battery in a TV remote! You replace them, they can't recharge.

Secandary cells, though, can be electrically recharged! Like your phone battery, plug it in and a few hours later, full battery.

Your answer would be "Secondary cells are rechargable"

Have a great rest of your day!

Axons of the nervous system are described as afferent and efferent according to the direction in which they carry information. W

Ahat [919]

Answer:

The correct option is b) motor output of the spinal cord

Explanation:

Motor neurons, also called afferent neurons, drive impulses from the brain and spinal cord to the receptors (eg, muscles). They are the motor output component of the spinal cord.

The spinal cord is a cord of nerve tissue that runs inside the spine. It conducts the nerve impulses that arrive from the receptors to the brain, and the responses with the motor orders from the brain to the effector organs. Thus, the brain receives the information and can develop an order that modifies the reflex response given by the spinal cord. A spinal nerve has two nerve roots: a motor and a sensory root. The motor root has nerve fibers that carry signals from the spinal cord, to the muscles to stimulate contraction and produce muscle movements, the fibers are efferent as they leave the medulla to the periphery through the anterior roots of the spinal nerves.

What it mean for something to be hypertonic?

Nady [450]

Hypertonic is where the solution has a lower water potential than the other side of the membrane. It has less water molecules and osmosis may occur under that in the presence of semi permeable membrane. Where water will flow from a higher water potential to lower water potential region
