Dioxin, produced as a by-product of various industrial chemical processes, is suspected of contributing to the development of ca

ncer and birth defects in animals and humans. It apparently acts by entering cells by simple diffusion and binding to proteins in the cytoplasm, then altering the pattern of gene expression. Which of the following are likely to be the cytoplasmic proteins to which dioxin binds? View Available Hint(s)
A. nucleosomes enhancers
B. DNA polymerases
C. transcription factors
D. growth factor receptors

Answer:

Transcription factors.

Explanation:

Transcription and translation are the two important process involved in the gene expression of a particular protein. Transcription is the formation of RNA and translation is the formation of proteins.

Transcription requires different enzymes and transcription factors. Transcription factors are important factors that regulates the expression of transcription and may increase or decrease the process of transcription. Here, the protein that binds with dioxin acts as the transcription factors as it regulates the gene expression.

Thus, the correct answer is option (3).

An unresponsive 41 lb (18.6 kg) child, with supraventricular tachycardia, is prescribed oral amiodarone 5 mg/kg. it comes as a s
Lostsunrise [7]
The answer is 1.9 millimeters. 
Solution
To get the mL value, you have to multiply the following:
(18.6 kg)(<span>5 mg/kg)(3mL/150mg)=mL
The technique here is that you have to think of isolating the unit you are finding and then you have to find a way that you can divide the units until you will find your needed unit. In the solution, you can see that kg/kg=1 and mg/mg=1 so the only unit left is mL. There you can get your answer. Don't be confused by the reciprocal of 150mg/3mL because it is only to get your needed answer.</span>

A tiger sprints across a field to hunt its prey. which molecule would provide the quickest energy for the tiger?
Paraphin [41]

Carbohydrate is the quickest energy for the tiger when it sprints across a field to hunt its prey.

Answer: Option C

<u>Explanation:</u>

Tigers are not opportunistic scavengers. When hungry they run catch their prey and devour it. For this they need energy. The Carbohydrates are the important source of energy.  

The carbohydrate break into smaller sugars called glucose. The glucose is stored as glycogen in the muscles and in the liver so that when need arises it releases energy. When in need the glucose at once gives energy for the active movement of the muscle which enables the tiger to sprint after its prey.

Do you think that the terms “closest evolutionary relationship” and “most common ancestor” used when describing the relationship
tatyana61 [14]

Answer:

<em>Yes, the above terms will be much similar.</em>

Explanation:

The term 'closest evolutionary relationship' reflects the organism or species which were the closest to different species in a phylogeny.

Most common ancestor also describes the ancestor from which two different organisms might have evolved.

Both the terms 'closest evolutionary relationship' and 'most common ancestor' show the common ancestors in a phylogenetic lineage. Hence, on evolutionary levels, both these terms have similar meanings and are often used to describe phylogenetic lineages.

The feature of endocrine system that makes it distinctly different from the nervous system is that it uses hormones distributed through the bloodstream, option(A).

<h3>Why is endocrine system distinctly different from nervous system?</h3>
  • The biggest difference between these two is that the endocrine system uses hormones produced by glands into the bloodstream, whereas the nervous system uses electrical impulses to send signals through neurons.
  • The signal transmission of the nervous system is fast because neurons are interconnected, but the functions are short-lived when compared to endocrine system.

Therefore, option(A) is the correct answer.

To know about differences between the two systems, refer:
