Answer:

All of the above.

Explanation:

Light and Water both are among the ecological factors .
Ecological factors are those components of environment which determine the variation in the chemical and physical nature of different ecosystem.
A balanced ecosystem needs to have all its ecological factors in adequate amount.
Thus, too much water, too much light, not enough light or not enough water , any of these condition can upset the balance of ecosystem.

Which is not something that occurs in translation? A codon and an anticodon pair. A peptide bond is created. A molecule of mRNA

Veseljchak [2.6K]

Answer:

A molecule of mRNA is formed.

Explanation:

Translation is the second process that occurs in gene expression. It is the process by which the information encoded in the mRNA transcript is used to synthesize a protein.

The mRNA nucleotide sequence is read in a group of three nucleotides called CODON. Each codon specifies an amino acid. Translation, which occurs in the ribosomes (cytoplasm), reads the codon with an anticodon using the complementary base pairing rule i.e. A-U, G-C. This means that a CODON-ANTICODON pairs.

The anticodon carries a corresponding amino acid to the polypeptide sequence. A peptide bond is formed when two amino acids joins together in a condensation reaction.

Note: A molecule of mRNA is formed during transcription

The hyperalgesia that is common in phantom limb pain could potentially be blocked if a new drug was developed that could prevent

gregori [183]

Answer: The answer is B- Diffusion of calcium ions through NMDA receptors.

Explanation:

Phantom limb pain (PLP) is a painful sensation experienced after the loss or amputation of a limb. The limb is no longer there but the individual can still feel real and severe pains in the limb. This occurs soon after surgery.

NMDA is a receptor for Glutamate which is an excitatory neurotransmitter. The activation of NMDA receptors are associated with hyperalgesia which is an abnormally heightened sensitivity to pain.

After 3 half lifes how many c-14 atoms would remain

ipn [44]

Answer:

Halife of C-14 is=14(RAM÷2)

You get=7 but further more let's say after 3 half life as your question stated it may result to decimal something which is impossible (as nucleons never be decimal)

Hence after 3half life it will continue to be 7

Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. true false

dolphi86 [110]

Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true

Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.
