Explain the role that the skeletal system plays in facilitating cardiovascular system function
Arturiano [62]

Answer:

Skeletal system provide strength and protection to heart and also produces essential blood cells such as RBC and WBC

Explanation:

All organ systems in our body work in co-ordination with each other. Skeletal system comprised of bones and cartilages while cardiovascular system comprises of hearts, blood and blood vessels. Firstly the skeletal system protects the heart and also assists in its pumping along with muscle. Secondly, the blood cells such as RBC and WBC are circulated by the blood throughout the body. However these cells are produced in the bone marrow (inside the bones)

In the early 1900s a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fac
Vladimir [108]
Let us go over the definitions and the functions of each term:
a) Gene is a bit vague but in general it means a part of DNA that encodes one protein. Genes are the building blocks of our genomes but not the answer to this question.
b)mRNA. This is correct. The name itself means messengerRNA and its role is to copy the genetic information in the nucleus and bring it outside to be translated into protein.
c) ATP is an important molecule in our metabolism; energy is stored in this molecule and then used. It has no relationship to the mechanisms concerning DNA.
d) Thymine is one of the 4 nucleotide bases that are found in DNA, the other three being guanine, cytosine and adenine. They are essential components of a nucleotide (building blocks of DNA and RNA) but again, they do not transfer information out of the nucleus.

Indicate whether each of the following descriptions better applies to COPI- (1), COPII- (2), or clathrin- (3) coated vesicles. Y
Nostrana [21]

Answer:

3212

Explanation:

Transport vesicles are vesicles that function to carry molecules from one cellular compartment to another. The coat protein complexes I and II (COPI and COPII) are conserved pathways that transport proteins from the endoplasmic reticulum to the Golgi apparatus. Moreover, clathrin is a protein implicated in the formation of coated vesicles. The ADP-ribosylation factor GTPase activating (Arf GAP) proteins play a major role in Arf signaling pathways, which are responsible for uncoating of the COPI coat. On the other hand, COPII vesicles are known to retain their coats until they are recognized by tethering complexes, and whose formation is regulated by the GDP-GTP cycle of the small GTPase Sar1. Finally, the 70-kDa heat shock proteins (HSP70) are chaperones which function as uncoating ATPases to remove clathrin from coated vesicles after endocytosis.

Crabtree effect on glycolysis
Afina-wow [57]

Answer: 'At high fructose concentrations, respiration is inhibited while glycolytic end products accumulate, a phenomenon known as the Crabtree effect. It is commonly believed that this effect is restricted to microbial and tumour cells with uniquely high glycolytic capacities (Sussman et al, 1980).
