<h2>Answer:</h2>

<u>Atom</u> is the primary as well as smallest unit of element.

<h2>Explanation:</h2>

Atoms are the tiny blocks that build elements. They are composed of proton, electron, and neutron. The electron is negatively charged, protons are positively charged, and neutrons are devoid of any charge.

The atom present in the elements combine with one another and leads to the formation of molecules. The property of the atom remains unchanged even after involved in formation of new molecules. When two atoms combine together it is called as molecules.

Why is it important for a cell to perform checks after DNA replication?
kifflom [539]

I hope it's an open question, since I can not find the statements.

The monitoring mechanisms are in addition to the regulation of the succession of the four phases of the cycle by the Cdk. They allow the monitoring of fundamental aspects such as the state of the DNA molecules before, during and after their replication (DDCP = DNA Damage Checkpoint), the total completion of the replication before the entry into mitosis (RCP = Replication Checkpoint ) and the correct positioning of all chromosomes on the metaphase plate before sister chromatid separation (MPC = Mitotic Checkpoint).

Disruption of the cell cycle leads either to cell death because the cell can no longer continue its cycle, in the worst case to anarchic proliferation. The major interest of the study of the regulation of the cell cycle and its points of surveillance lies in the fact that these processes are often unregulated in cancers. Knowing the regulation of the cell cycle is therefore fundamental for oncology and can be used to develop new therapeutic approaches.

Identify the position on the graph that gives the carrying capacity of the population.
Darina [25.2K]

The carrying capacity of any individual biological species is the maximum size of the population which can sustain indefinitely in that environment provided the necessary requirements like food, water and other environmental conditions are available.

The carrying capacity in the graph is the point on the graph where the line of population is horizontal. The graph has the population in y-axis and time period on x-axis. Alternatively if in the carrying capacity graph the line becomes parallel to x axis then it gives the carrying capacity. Here, at the point 2000 on y-axis and starting from 15 months in x-axis is the point of carrying capacity is marked with red horizontal line and green border in the image attached.

<h3>What number of nerves make up a pair?</h3>

The cranial nerves, a collection of 12 paired nerves, are located at the back of your brain. Your cranial nerves transmit electrical signals to your brain, face, neck, and body.

<h3>What are the 31 pairs of spinal nerves used for?</h3>

The peripheral nervous system, which consists of 12 cranial nerves and 31 pairs of spinal nerves, transmits nerve impulses from the central nervous system (CNS) to the rest of the body to control bodily activities.

Answer:

D) carbon dioxide

Explanation:

Carbon dioxide (CO2) is the most important greenhouse gas which is known to absorb heat that would otherwise be lost to space. It has been shown that CO2 causes approximately 80% of global warming. Different human activities, but especially the burning of fossil fuels, are the main cause of global warming. It has been estimated that 40 billion metric tons of CO2 produced by human activities are being discharged into the atmosphere annually. Other human activities associated with global warming by increasing the concentration of CO2 in the atmosphere include deforestation and cement production.
