I think the correct answer from the choices listed above is option E. Spindle fibers are present in all stages of mitosis. Spindle fibers<span> are aggregates of microtubules that move chromosomes during cell division.</span><span> Hope this answers the question. Have a nice day.</span>

The answer of the given description above is CORTISOL. Cortisol is a hormone and this is the one that stimulates the breakdown of fats in the adipose tissues. Once these are broken down, the fatty acids are released to the blood. Basically, when there is an increase cortisol in the body, this can help one lose body fats. Hope this helps.
A high-fiber diet might help decrease blood cholesterol levels by
a) preventing ketosis
b) keeping stools soft
c)trapping cholesterol in pockets in the large intestine
d)Causing fiber to bind with bile and more cholesterol to be excreted
Answer:
Causing fiber to bind with bile and more cholesterol to be excreted
Explanation:
High fiber diet include whole grain cereals, fruits, vegetables, nuts and potatoes etc., when consumed,they bind with cholesterol to aid degeneration in order for excretion to occur. They aid digestion and increase bowel movement, helps the body to lose weight, stay full longer, and improve health.
Answers:
a) carcinogenic
b) anti-carcinogenic
c) carcinogenic
d) carcinogenic
e) carcinogenic
f) anti-carcinogenic
g) anti-carcinogenic
h) anti-carcinogenic
Explanation:
Cyclins are proteins that regulate the progression through the cell cycle, i.e., the transition of G1 to S phase. It is well known that high cyclin expression may lead to cell proliferation states, which is closely associated with cancer progression. Moreover, the blockage of cyclins may have an anti-carcinogenic effect by inhibiting the progression through the cell cycle. MAP kinases are serine/threonine kinases that regulate the progression through the cell cycle by phosphorylating a variety of substrates during cell proliferation. In consequence, phosphatases that inactivate MAPK kinases (i.e., by dephosphorylation) may have an anticarcinogenic effect. The p53 is a tumor suppressor protein involved in diverse cellular processes including DNA repair, cycle arrest and programmed cell death. This protein (p53) is activated by phosphorylation at target residues and phosphatases inactivate it, thereby the blockage of its degradation may have an anticarcinogenic effect. Oncogene activation (i.e., the expression of oncogenes), may alter diverse cellular processes including DNA replication, and thereby may lead to cancer development. The G-protein α subunit is a GTPase that hydrolyses GTP and thus has a major role in controlling the kinetics of the G-protein signaling cascade. Platelet-derived growth factor receptors (PDGFR) are kinase receptors that play roles in regulating cellular differentiation, cell proliferation and cell growth. PDGFR receptors are present on the surface of normal cells, however, it has been shown that mutations of the PDGFR genes that lead to their high expression lead to uncontrolled cell growth and consequently cause cancer (i.e., by increasing PDGF signaling).
