Describe 2 way cancer might arise from problems with the cell cycle

Biology
1 answer:
nikdorinn [45]3 years ago
7 0

Answer: First, p53 triggers production of Cdk inhibitor proteins, pausing the cell cycle in G1 to allow time for repairs. ... In cancer cells, p53 is often missing, nonfunctional, or less active than normal. For example, many cancerous tumors have a mutant form of p53 that can no longer bind DNA.

Which of the following statements correctly describes the relation between frequency, wavelength energy and velocity of a wave t
Sedbober [7]

The statement that correctly describes the relation in the question is ; ( A ) As wavelength decreases, frequency increases, energy increases and the speed remains the same.

The Frequency of a wave travelling in a medium is directly proportional to the energy produced by the wave and inversely proportional to the wavelength of the wave.  

Changes in the wavelength and frequency of a wave has no effect on the wave speed. but has an effect on the energy produced by the wave. therefore the wave speed remains constant regardless of the changes in wavelength and frequency

Hence we can conclude that   As wavelength decreases, frequency increases, energy increases and the speed remains the same.

Applying fungicides to plants may result in the plants showing signs of phosphorus deficiency. What is the most likely explanati
Umnica [9.8K]

Answer:

The fungicide destroys mycorrhizal symbionts.

Explanation:

Mycorrhizal symbionts is the symbiotic association that is present between plants and fungi. Plants provide food materials in the form of sugar to the fungi while fungi fixes phosphorus for the plant that is present in the soil in unavailable form. When fungicide is sprayed, it kills the fungi present in the soil and deficiency of phosphorus occurs in plants.

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.
