evaluate the statements below and determine which is the best reason that bacterial cells use operons and polycistronic rna.
Given what we know about bacterial cells and their genetic mechanisms we can confirm that they use operons and polycistronic RNA for efficiency.
Bacterial cells are vastly different from human or animal cells. Some of these differences include:
Lack of compact DNALack of organelle surrounded by plasmatic membranesThey have cell wallsMay possess flagellaand many others.
Among these differences is the way in which they encode for the proteins the bacteria will produce. Unlike human cells, bacteria use polycistronic RNA. Where a human strand of mRNA will carry the genetic message to create one protein, the polycistronic mRNA of a bacterial cell will provide the information necessary to create multiple distinct proteins.
Bacteria use this in conjunction with operons, to create very efficient protein manufacturing processes. Operons are sections of DNA in which proteins with similar functions are grouped together in order to make it easier to create the polycistronic mRNA strands.

Our sun is a low mass main sequence star at the middle of its life cycle. Explain how the
appearance of the sun's location on the HR diagram will change as it continues to the end of
its life cycle.
Answer:
Accordingly, when our Sun comes up short on hydrogen fuel, it will grow to end up a red monster, puff off its external layers, and after that settle down as a minimal white small star, at that point gradually chilling off for trillions of years. All incredible, in the long run — in around 5 billion years — our sun will, as well. When its supply of hydrogen is depleted, the last, sensational phases of its life will unfurl, as our host star extends to wind up a red Goliath and afterward shreds its body to consolidate into a white smaller person Explanation:

Which is a homologous structure to the human forearm?
O A. The beak of a bird
OB. The skull of a raccoon
O C. The tail of a dog
O D. The leg of a horse
The homologous structure to the forearm of humans is the leg of the horse.
What are homologous organs?Homologous organs are organs that share similar structural organization. They are similar structurally but are different in functions. They share common ancestors. These organs are anatomically similar. As there are common ancestors, this type of evolution is known as divergent evolution.
The reason behind the divergent evolution is environmental changes, and food requirements which force them to evolve according to the requirements. The wings of bats, the forearms of humans, and the front legs of the horse are a few examples of homologous organs which underwent divergent evolution.
Homologous organs have different functions in organisms.

_______ are a result of hurricanes, which push massive amounts of water inland, causing severe damage.
Answer:
Warm ocean air rises into the storm
Explanation:
Most of us know that heat rises so when the heat from the ocean rises it adds into the storm and creates a low-pressure area under the clouds which then continues to build heat and the winds reach to around 74 MPH to be classified as a hurricane.

the sympathetic chain of ganglia is found at the __________ levels of the spinal cord.
Answer:
lateral and venteral
Explanation:
the chain extends from the upper neck down to the coccyx, forming the upward coccygeal gangilion
The sympathetic chain of ganglia is paravertebral and is loaded just ventral and lateral to the spinal cord. As they extend from the upper bottom forming an unpaired ganglion.
They function as a major part of the sympatric nervous system. Hence they function at various levels of the spinal cord as the cervical, the thoracic, lumbar, sacral, and coccygeal.Learn more about the chain of ganglia is found at the.

which receptors respond to stimuli within the body?
Answer:
Sensory receptors respond to stimuli.
Explanation:
They can be classified by their location, the type of stimulus they detect or by their structural complexity.
Sensory receptors are the receptors which respond to stimuli within the
body. The body have five major sensory organs which include the eyes,
nose, tongue, ear and skin.
These organs have receptors which is responsible in the transmission of
signal to the brain for action. The brain acts depending on the signal
received which is usually in the body's best interest.
This makes our sensory organs important and very delicate and as a result
should be adequately protected and taken are of.

C. What happens at point D? (1 point)
Question 2
Answer the question below about Smokey The Mouse.
A. Use inertia to explain how a balanced force will affect his motion. (Newton's 1st Law)
B. What are two ways Smoky can increase his speed? (Use Newton's 2nd Law to help you)
C. What is an example of an action and reaction at work in this picture? (Use Newton's 3rd Law to help you)
The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.
At point B, Alberto's distance covered increases with time, equal distance is covered in equal time interval. The speed increases uniformly. At the point C to D, the distance covered with time remains the same. At the point D, equal distance is no longer covered in equal time intervals.
According to the law of inertia, an object will remain at rest or in a state of uniform motion unless it is acted upon by an unbalanced force. This means that smokey mouse will continue moving uniformly unless a force acts on it.
From Newton's second law; F = ma and a = F/m. F = force , m= mass, a = acceleration. This implies that smokey mouse can increase its speed by;
Increasing the force acting on the mouseDecreasing the mass of the mouseAction and reaction is encountered as the mouse is walking. The mouse exerts a force on the ground and the ground exerts an equal and opposite reaction force on the mouse.

Plants that we reconize today spend the majority of their life in the “blank”
A) haploid Phase
B) seed phase
C) diploid phase
D) gametophyte
Answer:
The answer is C diploid Phase
Answer:
The answer is C.
Explanation:
Plants that we reconize today spend the majority of their life in the diploid phase.
During the sporophyte phase, a diploid plant body (one with two sets of chromosomes) develops and finally generates spores via the process of meiosis. Mitotic division of these spores results in the formation of gametophytes, which are gamete-producing organisms that are haploid (have a single pair of chromosomes).

How does the cell membrane occur in cellular respiration ?.
Colchicine is a toxin that binds to tubulin proteins and prevents microtubules from elongating. What effect might this have on dividing cells
The effect Colchicine might have on dividing cells is that the duplicated chromosomes might not be able to segregate into daughter nuclei.
Colchicine is an alkaloid that attaches to tubulin and prevents it from polymerization to microtubules. As we know that Microtubules are a component of the cytoskeleton of a cell that aids in molecular mobility inside the cell.
During cell division, chromatin condenses into chromosomes, which are then connected to microtubules. The chromosomes are separated into daughter cells by microtubules.
When these cells are treated with colchicine, tubulin polymerization to microtubules may not occur, and the chromosomes containing daughter nucleic might not be separated.
