Suppose that an unusually high degree of aurora kinase activity is observed in the cervix. What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage
Answer:
The division of cervical cancer cells will be inhibited
Explanation:
Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.

Which piece of evidence would strongly support the RNA-first hypothesis? finding a protocell that could carry on metabolism as well as reproduce discovering a way to make RNA more stable than DNA finding a mechanism whereby proteins could assemble DNA out of free nucleotides being able to build microspheres that contain only protein and RNA finding a living organism that uses RNA as its genetic material
Answer:
The correct answer is - finding a living organism that uses RNA as its genetic material.
Explanation:
The RNA world theory recommends that life on Earth started with a simpler form of RNA particle that could duplicate itself. The RNA world speculation recommends that life on Earth started with a basic RNA particle that could duplicate itself without assistance from different atoms.
The RNA world theory is upheld by RNA's capacity to store, transmit, and copy hereditary data, as DNA does. RNA can go about as a ribozyme, an uncommon kind of enzyme. Since it can play out the role of both DNA and enzyme, RNA is accepted to have once been equipped for supporting free living things.
According to the hypothesis is that RNA, a nearby relative of DNA, was the main hereditary atom to emerge around 4 billion years back, however in a simpler form of life that later developed into the RNA and DNA particles that we have in life today
Thus, The correct answer is - finding a living organism that uses RNA as its genetic material

does a fire take food for energy?
does a fire reproduce?
does a fire produce waste?
Answer:
Yes, a fire takes food for energy.
No, a fire doesn't reproduce.
Yes, a fire produces waste.
Explanation:
For fire, the food that it requires is the objects that help in the process of burning. The objects can be wood, paper, coal, fuel, etc. Oxygen is required for the process of burning to take place.
The process of reproduction undergoes in living beings. Fire produces heat and light but this cannot be termed to be a process of reproduction.
Burning produces wastes in the form of ash and burned products. Therefore, it can be said that fire produces wastes.

Gastrin, histamine, endorphins, serotonin, cholecystokinin, and somatostatin are hormones or paracrines that are released directly into the lamina propria. Which of the following cell types synthesize and secrete these products?
a) parietal cells
b) enteroendocrine cells
c) mucous neck cells
d) zymogenic cells
Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.

Describe how living things are involved in the constant cycling of carbon.
Answer:Most living things breathe out carbon dioxide(Co2)
Explanation:
Most living organisms need oxygen to survive(Animals and microorganisms).They therefore breathe in oxygen and breathe out carbon dioxide save for green plants which give out oxygen and take in carbon dioxide.
Animals and plants exchange oxygen for carbon dioxide and vice verca
Hereby involving living things in the constant cycling of carbon dioxide in the atmosphere.

Which type of process occurred in the ecosystem that was affected by the 1988 fires in Yellowstone Park, which destroyed most of the vegetation but left the soil intact? primary succession secondary succession a climax community species extinction
The correct answer is B. Secondary succession
Explanation:
In ecosystems, secondary succession occurs as certain events such as fires cause vegetation to temporarily disappear from one area. However, as soil is not affected negatively, vegetation grows again after some time, which means there is a secondary growth of vegetation and changes in the structure of an ecological community.
This term applies to the situation in the 1988 fires in Yellowstone Park because the fire destroyed the vegetation in the zone temporarily, but as the soil was intact after years or decades the vegetation will grow again, although this might implied changes in the ecosystem.

Answer:
The correct answer is - particulate inheritance.
Explanation:
The theory of particulate inheritance expresses that discrete "particles" are passed from one generation to another generation offspring. While Mendel utilized the term particles, we presently realize that these particles are really genes.
For instance, codominance in the flower of two distinct colors present in the different alleles of genes expressed or visible together without mixing and can be communicated distinctively in later generations individually.

You are working to catalogue some of the species in the Amazon rainforest
before they become extinct from logging. You collect 3 organisms that all look
similar to the Coral snake and do a phylogenetic analysis on them before
classifying and naming them. The Coral snakes DNA barcode is
ATTCGCGATAC. Compare it to each sample organism's DNA barcode to
determine how related they are to the Coral Snake, from closest to furthest.
Organism 1: ATTGGCCATAC
Organism 2: ATCCGGGATAG
Organism 3: ATTCGCCATAC
Answer:
The organism closest to the coral snake is organism 3, followed by organism 1 and finally organism 2.
Explanation:
The more similar the DNA composition of the organisms, the closer and more closely related they are. With that we can say that the coral snake is closer to organism 3, since the sequence of nitrogenous bases in its DNA is more similar, in relation to other organisms. After organism 3, it is organism 1 that most resembles a coral snake. Organism 2, however, has a different DNA composition, the organism being less similar and the more distant from the coral snake.

How do you think pollination takes place in flowering plants?
Answer:
My answer is down below.
Explanation:
Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species take place. After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begins to grow a tube. This tube is called the pollen tube.
Explanation:
insects typically pollinate flowers as they move from plant to plant searching for food. when an instects lands on a flower to feed, pollen grains sticks to its body. As the instects moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs.
