Answer:
Average speed of jogger,s=72.46 m/min
Explanation:
Total distance covered by a body divided by the elapsed time to cover that distance is known as average speed of that body.
We have given length of track=100m
Therefore total distance covered by the jogger,
[tex]d=100m+100m\\d=200m[/tex]
Total time taken by joggers to cover 200m distace,
[tex]t=1.13 min+1.63m[/tex]
t=2.76 min
Therefore average speed of jogger,
[tex]s=\frac{d}{t}[/tex]...............(1)
put values of d and t in equation 1
we got,
[tex]s=\frac{200 m}{2.76 min}[/tex]
average speed of jogger,s=72.46 m/min

Dense Denise is an emergency room nurse at Hopeless Hospital. She notices that the hospital is running short on blood, so she decides to dilute the blood with water to make it last longer. Later, Dr. Dingo, the attending physician gets ready to give a patient a transplant. As a precaution, he puts a sample under the microscope, sees this image. He immediately begins angrily barking at Denise. What happened to the blood cells?
Answer:
The answer to the question: What happened to the blood cells, when Denise, the nurse, put the blood samples with water, to dilute the blood so that it would last longer, is, that the blood cells, through the process of osmosis, took in the water around them, swelled and ruptured.
Explanation:
Usually, when putting a pack of red blood cells inside a water solution will activate the cellular process of osmosis, which means, that the membrane of the cell allows water to trickle into it, as the volume of water outside the cell is higher than inside. In the process of equilibrium of concentration, the cell allows the water in, but it reaches a point when the amount in is too much and thus the cell bursts. What Dr. Dingo found under the microscope, then, was the red blood cells burst due to the water.
images observed under the light microscope are reversed and inverted . explain what this meand
Final answer:
The optics of a microscope's lenses invert the image, resulting in a specimen appearing upside-down and reversed from its original orientation. This effect is due to the way light is manipulated by the microscope's dual-lens system. Certain types of microscopes include additional systems to correct this inversion.
Explanation:
The optics of a microscope's lenses dramatically alter the orientation of the image seen by the user. When a specimen that is oriented right-side up and facing right on the microscope slide is observed through a microscope, it will appear upside-down and facing left, and vice versa. This inversion happens because microscopes utilize two sets of lenses to magnify the image. How light travels through these lenses results in the observed image being flipped. Essentially, this dual lens system produces an inverted image. In contrast, binocular or dissecting microscopes, despite working similarly, incorporate an additional magnification system that corrects this inversion, presenting the final image as upright.

Cartilage, fat, tendons, ligaments: these are all examples of _______ tissue that ________. A) integumentary; bind the body together B) connective; bind and support the body C) skeletal; support and protect the body. D) muscular; support the body and help it move.
Answer: B). connective; bind and support the body.
Connective tissues are tissues which connect, support, binds other tissues and organs of the body. They play a role of external lining of the body cavity. They have typically few cells embedded in an amorphous matrix along with collagen and other fibers.
Cartilage is a type of fibrous connective tissue that is made up of closely packed collagen fibers. It provides flexibility to structures like nose, trachea and ears in humans.
Fat or adipose tissue is a loose connective tissue that provides lining to the body organs and cavities hence, maintains the connectivity and prevents heat loss.
Tendon is a type of fibrous connective tissue which connects muscles to bone.
Ligament is a type of fibrous connective tissue which connects bone to bone.
All these connective tissue make a binding link between muscles, bones, organs and cavity which is necessary for providing support to the body.

Which of the diagrams below shows what one would see in the electron microscope during the transcription of a polycistronic bacterial operon that codes for two proteins?
The correct answer is: 4
For the first question about the electron microscope diagrams during the transcription of a polycistronic bacterial operon that codes for two proteins:
In polycistronic operons, multiple genes are transcribed into a single mRNA molecule. This mRNA molecule contains information for the synthesis of multiple proteins. In electron microscopy, you would see the transcription process as a continuous strand of RNA being synthesized. Among the given options, the correct choice would be: D
As for the second question about the number of different polypeptides translated from the [tex]mRNA 5'-GUAGUAGUAGUA... - $3^{\prime}$:[/tex]
The start codon for translation in most organisms is AUG. However, the given mRNA sequence does not start with AUG, and it's mentioned that translation does not need to start at AUG.
In this case, every codon in the mRNA sequence GUAGUAGUAGUA could potentially serve as a start codon. This means that the reading frame can begin at any of the four GUA codons. Therefore, there are 4 different potential reading frames, and each would produce a different polypeptide.
So, the correct answer is: 4

What is evolution?
Evolution has been the scientific theory that explains that "a change in the characteristics of biological populations over next generations." According to the scientists RNA has been known as the first existing molecule on the earth that replicate by itself and the process of the evolution lead to advanced forms of life.
These characteristics has been easily trasfered from one generation to other generation. Organisms evolve over the time due to changes in the heritable physical characteristics which has been an example of a scientific theory known as evolution.
