Energy of activation?

Medicine
1 answer:
Blababa [14]3 years ago
8 0

Answer:

c. Minimum amount of energy for the reaction to occur

Explanation:

The "energy of activation" or <em>"activation energy"</em> refers to the minimum amount of energy for the reaction to occur or the<u> minimum amount of energy needed for molecules to go through a chemical reaction.</u> It is commonly measured in J/mole<em> (Joules per mole).</em>

The activation energy was termed by Svante Arrhenius, a Swedish scientist. He also developed a formula in order to show the relationship between the activation energy of the chemical reaction and its rate. He proved them to be indirectly proportional. The higher the activation energy, the lower the chemical rate.

Pachacha [2.7K]

Answer: Firstly put your finger under some cold water and light dry it with a towel. If you have aloe Vera that would be great but don’t use lotion or any other face cream/body cream because it will irritate the burn and eventually your finger. Lastly keep your finger away from anything that can harm it such as paper, once the aloe Vera dries apply more until you feel comfortable to put a band aid on your finger

Hopefully your finger gets better fast :)

The nurse suspects that an older adult client has a basal cell carcinoma. what finding did the nurse use to make this clinical d
777dan777 [17]

The nurse suspects that an older adult patient has features of basal cell carcinoma appearing in form of a small dome-shaped lesion with a pearly surface on the face.

What is Basal cell carcinoma?

The most prevalent type of skin cancer that is not melanoma is basal cell carcinoma (BCC).

  • It is a tumour that causes localized damage and has a variety of clinical and histological characteristics.
  • When viewed at low power magnification, a basaloid epithelial tumour emerging from the epidermis is the primary characteristic of basal cell carcinoma.
  • Normally, the palisade-like basaloid epithelium forms a fissure from the surrounding tumour stroma.

The nuclei grow congested in the centre, with scattered mitotic figures and visible necrotic bodies.

The presence of a mucinous stroma serves as a helpful distinguishing factor from other basaloid cutaneous tumours. Additionally, some tumours may exhibit foci of regression, which are regions of eosinophilic stroma devoid of basaloid nests.

Hence, the answer is a small dome-shaped lesion with a pearly surface on the face.

What happens to a cell as the virus produces its progeny?
VladimirAG [237]

Answer:

Cells that support viral replication are called permissive. Infections of permissive cells are usually productive because infectious progeny virus is produced. Most productive infections are called cytocidal (cytolytic) because they kill the host cell. Infections of nonpermissive cells yield no infectious progeny virus and are called abortive. When the complete repertoire of virus genes necessary for virus replication is not transcribed and translated into functional products the infection is referred to as restrictive. In persistent and in some transforming infections, viral nucleic acid may remain in specific host cells indefinitely; progeny virus may or may not be produced.

Explanation:

Hope this helps! :)

Norepinephrine acts on the heart by _________
Westkost [7]

Answer:

The correct option is : a. causing threshold to be reached more quickly      

Explanation:

Norepinephrine, also known as noradrenalin, is an organic compound, which belongs to the catecholamine family. It acts as a hormone and a neurotransmitter in the brain and the body and also impacts the heart.

It is one of the hormones secreted by the adrenal medulla. Norepinephrine is a part of the fight-or-flight mechanism of the body. It acts by binding to the β-1 receptors and opens the chemical or ligand gated calcium and sodium ion channels. Therefore, <u>it causes the threshold to be reached faster </u>by increasing the rate of depolarization and thus causes heart arrhythmia.

Therefore, <u>Norepinephrine acts on the heart by </u><u>causing threshold to be reached faster.</u>
