Answer:
Apoptosis in Cancer
The loss of apoptotic control allows cancer cells to survive longer and gives more time for the accumulation of mutations which can increase invasiveness during tumor progression, stimulate angiogenesis, deregulate cell proliferation and interfere with differentiation
Many oncogenic stresses, including uncontrolled proliferation or DNA damage, trigger apoptosis; consequently, by culling cells at risk of transformation, apoptosis effectively prevents cancer. Apoptosis also suppresses tumourigenesis in various other ways.
The more malignant the tumour is, the more apoptosis shows. In this study, we propose a new theory that apoptosis plays a key role in the malignant progression and metastasis of cancer. The growth of tumour is the difference between tumour cell proliferation and attrition plus the hyperplastic growth of stroma.

m ) M How many milliliters of 0.750 M H2PO4 are required to react with 250. mL of 0.150 M Ba(OH)2 if the products are barium phosphate and water?
The volume of phosphoric acid is mathematically given as
X= 75 mL of H3PO4
What is the volume of H2PO4 required?Question Parameters:
Milliliters of 0.750 M H2PO4 are required to react with 250. mL of 0.150 M Ba(OH)2
Generally, the equation for the banlanced Chemical Reaction is mathematically given as
2 H3PO4 + 3 Ba(OH)2 ------> Ba3(PO4)2 + 6H2O
Therefore
The volume of phosphoric acid=[tex]\frac{3*2*250*150*3*1}{1*2*750}[/tex]
The volume of phosphoric acid=0.075 L of H3PO4
In conclusion, the volume of H2PO4 in mL is
The volume of phosphoric acid=75 mL of H3PO4

What is food web?
"A food web consists of all the food chains in a single ecosystem. Each living thing in an ecosystem is part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem."
What is food chains?"A food chain is a linear sequence of organisms through which nutrients and energy pass as one organism eats another."
What is the difference between food chain and food web?A food chain follows a single path, where animals discover food. But a food web shows different paths, where plants and animals are connected. A food web comprises several food chains.In a food chain, an organism eats a single item, whereas in a food web an organism consumes multiple items. In a food chain, there is a singular path for energy flow and in a food web, there are different paths for energy flow.To know more about food web here https://brainly.com/question/2233704

Prior to Mendel completing and publishing his genetic experiments, what were the prevailing ideas about how inheritance occurred
Before Mendel's work, many hypotheses were proposed to try to explain heredity. The best known of them is that there were small animals inside the man, which were called animalcules. In man, this miniature became known as a homunculus.
What was genetics like before Mendel?The first ideas about heredity were quite simple and only claimed that children were similar to parents, without understanding the mechanism behind this finding. Genetics is the part of Biology that studies heredity, that is, the way in which characteristics are passed on from generation to generation.
With this information, we can conclude that Before Mendel's work, many hypotheses were proposed to try to explain heredity. The best known of them is that there were small animals inside the man, which were called animalcules. In man, this miniature became known as a homunculus.

If a enzyme denatures, it slows down because:
• It begins to use a new substrate
• it gets bigger and can’t move
• it changes shape and the substrate won’t fit
• it become to small
Answer:
The answer would be "C" because when an enzyme denatures, it changes it shape so that the substrate won't fit anymore. On a side note, when an enzyme is placed in an environment out of its pH or tempertaure range, it can denature.
How does denaturation of a protein affect its function?.

What role do surface properties play in determining the lifespan of a flu virus?
Answer:
Surface properties have less to do with virus lifespan than does the type of virus. Viruses tend to remain viable for longer on non-porous materials than on porous ones. Viruses tend to remain viable longer on surfaces with low moisture content.
Explanation:
The surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
Influenza (flu) viruses are contagious viral infections capable of affecting the airways of the lungs.It has been shown that flu viruses survive on human tissues for only 15 min because of their surface properties.Moreover, it has been shown that these viruses cannot survive on non-porous metal/plastic surfaces by more than 9 hours.In conclusion, the surface properties in the lifespan of a flu virus are associated with the fact that viruses tend to remain viable for longer on non-porous materials than on porous ones.
