An exon is considered a coding sequence of dna, and its information is retained in the processed mrna within a cell. True or false?.
It is true that An exon is considered as the coding sequence of the dna, and its information is retained in the processed of mRNA within the cell.
The sequence was of DNA present in the mature messenger the RNA, some of which the encodes the amino acids of the protein. Most of the genes have the multiple exons with the introns between them. introns are the noncoding sections of an RNA transcript, or the DNA encoding it, that are also spliced out before the RNA molecule which is translated into the protein. The sections of the DNA (or RNA) that code for the proteins are called as exons.

A student has a pure culture of bacteria growing in a flask and wants to know how many living cells are in the culture at a given time. Plate counting is the method should she employ to get an estimate.
It is a technique to determine the number of living cells in a sample using different steps.
The sample (1g) is first diluted with a suitable diluent (9g) and then mixed together. This solution is then added to another (9g) diluent. It is repeated to get a number of series.
The sample is then plated on an agar plate. These plates are then moved to an incubator at a suitable growth temperature.
We then calculate the plates having colonies between 50-300. Now we have to calculate the number of organisms that were in the original sample.

Scientist Galileo Galllel used the
to observe the stars and planets. This same tool has allowed modern
to see objects that are billions of light years from Earth. This tool also detects things such as
and x-rays, which are invisible to the human eye.
Answer:
1. telescope
2. astronomers
3. radio waves
Explanation:
A telescope allows one to magnify what they're looking at to see it closer than it actually is. Astronomers are those that study planets, stars, and other celestial bodies in space. Modern telescopes have the ability to detect radio waves from astronomical objects that emit them from far away. This allows us to see what we normally would not be able to.
Scientist Galileo Galilei used the telescope to observe the stars and planets. This same tool has allowed modern astronomers to see objects that are billions of light years from Earth. This tool also detects things such as gamma rays and x-rays, which are invisible to the human eye.
Galileo observed the night sky and made several revolutionary findings, such as the discovery of the four largest moons of Jupiter, the phases of Venus, and the craters and mountains on the Moon. These observations provided compelling evidence for the heliocentric model of the solar system proposed by Copernicus, where the Sun is at the center, and the planets, including Earth, revolve around it.
Galileo's use of the telescope marked a pivotal moment in the history of astronomy, as it allowed scientists to explore the cosmos in unprecedented ways. Fast forward to modern times, and telescopes have undergone significant advancements and technological improvements. Modern astronomers now have access to powerful telescopes, including space-based telescopes like the Hubble Space Telescope, which can observe objects that are billions of light-years away from Earth. These telescopes have provided stunning images and data of distant galaxies, nebulae, and other celestial phenomena, shedding light on the vastness and complexity of the universe.

Many bacteria and fungi have a difficult time surviving on our food if the food is very salty. The best explanation for this is.
Many bacteria and fungi have a difficult time surviving on our food if the food is very salty. This happens because the food acts as a hypertonic solution for the bacteria and fungi.
Bacteria are the microorganism that are prokaryotic in nature. These are unicellular organisms present everywhere in an environment. These can be of varying shapes and sizes like coccus, spirillum, vibrio, etc. Bacteria can be both harmful as well as useful for the organisms and environment.
Hypertonic solution is the one in which when any cell is placed, it loses its water. The solution contains more solute particles than the cell placed in it. As a result of osmosis, water moves out of the cell. The same phenomenon happens with bacteria in salty foods, it loses its water and becomes dehydrated.

c. Scientists always use controlled experiments.
d. Controlled experiments cannot be performed
on living things.
Answer: The controlled experiments are performed by the scientists when they want to study the changes in the sample by changing a single variable. So, the correct answer is option (b).
Explanation:
In case, all variables are kept same, no changes would be observed in the experiment sample. A controlled experiment can be performed on living things as well as non-living. But, controlled experiment cannot be performed on the things which are influenced by a lot of variables, as they cannot create realistic results. So, the option (a), (c), and (d) are incorrect.

Diseased animal cells may produce molecules that activate death cascades to kill the cells in a controlled manner. Why would neighboring healthy cells also die?.
Answer:
neighbouring healthy cells will die when molecules activate death cascades because the death molecule passes through gap junctions.
the blood flow of healthy individuals is laminar but becomes turbulent during certain vascular diseases. endothelial cells (ecs), which line the lumen of blood vessels, are in direct contact with blood. you hypothesize that different types of blood flow (i.e. laminar vs. turbulent) may cause endothelial cell dysfunction which in turn contributes to the progression of diseases. to test this hypothesis, you fabricated a microfluidic device in which ecs were seeded inside a rectanugular channel of prescribed width
Blood flows in orderly, parallel layers through the arteries in laminar flow when there are no impediments to disturb the layers. A healthy artery, like the femoral artery, exhibits laminar flow.
When the flow channel becomes disordered, layers fail to form, and eddy currents develop, the scenario is referred to as turbulent flow.
The current vascular hemodynamics paradigm views typical blood flow as pulsatile laminar flow. Diseases like atherosclerosis and brain aneurysms can be brought on by the transition to turbulence. But recently, we showed that turbulence can exist in both the aneurysm sac and the main artery of experimental models of brain aneurysms.
The necessity for even mixing of blood corpuscles as they travel along the arteries drives the turbulence of blood flow, which originates in the cardial cavities. We think that the energy expended might be sufficient to overcome a resistance in the main arteries, where the wall lacks active contraction components.
Small arterial micro vessels (Metereriolar-like type) have a similar inner wall relief that must be extruded into the lumen of the nuclear zone of the endothelial cell. However, blood movement within arterial micro vessels is highly dependent on the myogenic wave activity of intramural smooth muscle cells.

All five domains are related to sustainable development because they are the 5 domains of sustainability.
Sustainability has always been portrayed as having three domains: the environment, economics, and the socio-cultural milieu, and they must be managed interdependently for a sustainable balance to occur (i.e., the Bruntland Commission of the United Nations, 1987). Many business and political leaders have expressed skepticism about equating another field with economics.
Even those who will adopt the ideals of living in harmony with nature frequently discover that the instruments available in these three spheres are inadequate.
