Answer:
v = 5 m/s
Explanation:
Given that,
The distance covered by a runner, d = 400 m
Time, t = 80 sec
We need to find the runner's average speed. It is equal to total distance covered divided by time taken. It can be given by:
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{400\ m}{80\ s}\\\\v=5\ m/s[/tex]
So, the runner’s average speed is 5 m/s.
Multiply (2x + 5)(3x - 4).
Answer:
6 [tex]x^{2}[/tex] + 7 x − 20

Photosynthesis and cellular respiration differ in which of the following
ways?
O The main source of chemical energy in cellular respiration is water.
The energy conversion in cellular respiration takes place in the chloroplast.
O The main source of energy in cellular respiration is glucose.
The final product of cellular respiration is electromagnetic radiation.
Answer:
the main source of energy in cellular respiration is glucose.
Explanation:
photosynthesis creates glucose out of co2 h2o and sunlight. while cellular respiration is almost exactly the opposite.
The ways in which photosynthesis and cellular respiration differ is that the main source of energy in the case of cellular respiration is glucose. Hence, Option C is the correct answer.
The photosynthesis and cellular respiration processes are interlinked with a significant relationship. The products of one process act as reactants in the other. Some of the significant differences between both processes are mentioned as follows:
Photosynthesis takes place only in phototrophs such as plants and algae while cellular respiration can take place in all the living forms. Photosynthesis completely takes place in chloroplasts and cellular respiration in Mitochondria. Glucose is made by the process of photosynthesis while glucose is utilized in cellular respiration to make molecules of ATP.Thus, we can conclude that photosynthesis and cellular respiration differ specifically by the main source of energy. Hence, option C is the correct answer.

What is the male reproductive system?The male reproductive system is made up of internal organs including the prostate gland, vas deferens, and urethra as well as external genitalia like the testes, and scrotum.
The health of the male reproductive system and the hormones secreted by the brain determine a man's fertility and sexual characteristics. The male reproductive system is in charge of both urine and sexual function.
They create, retain, and move sperm and semen, which are the male reproductive cells (the protective fluid around sperm).
Therefore, sperm is released into the female reproductive system by them. Male sex hormones are created and secreted by them.

Will the hurricane gain strength or lose strength if it moves from warm water to cold water? Explain in 3-4 sentences
Answer:
Explanation:
As long as the base of this weather system remains over warm water and its top is not sheared apart by high-altitude winds, it will strengthen and grow. More and more heat and water will be pumped into the air. The pressure at its core will drop further and further, sucking in wind at ever-increasing speeds. Over several hours to days, the storm will intensify, finally reaching hurricane status when the winds that swirl around it reach sustained speeds of 74 miles per hour or more.

HOW DOES THE MEIOSIS PROCESS WORK ?
What is different between meiosis and mitosis?
Whats the different between haploid and diploid?
Answer:
Meiosis is broken down into several stages. Each cell in the process of meiosis involves the cell growing, dividing, splitting, and dividing again in order to produce the four cells at the end of the process. This cellular process is one of the more common processes of biology, but it is also the reason why people have some traits over others.
Explanation:
The difference between mitosis and meiosis is in the process by which each form daughter cells from a parent cell. Mitosis has one round of cellular division and genetic separation whereas meiosis has two rounds.
The key difference between haploid and diploid is that haploid is the state of having half the usual number of chromosomes while diploid is the state of having the usual number of chromosomes in the genome of a cell.
Set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks. Each set was watered daily with 50 mL of a 0.1% fertilizer solution. Which statement best explains why the green plants died and the mushrooms survived?
Answer:
This question lacks options, however, it can be answered based on general understanding.
The green plant died because of absence of LIGHT
Explanation:
Plants (green) are autotrophic organisms i.e. organisms that are capable of synthesizing their own food via a process called PHOTOSYNTHESIS. However, on the other hand, mushrooms (kingdom FUNGI) are heterotrophic organisms i.e. rely on other organisms for energy source and cannot make their own food.
Green plants strictly require light energy from the sun in order to perform the process of photosynthesis. According to this question, a set of 25 green plants and 25 mushrooms were put in a cool, dark room for two weeks and watered daily with 50 mL of a 0.1% fertilizer solution. The green plants, despite the nutrients and regular watering dies because they were not exposed to LIGHT in order to make their food via photosynthesis. However, since light is not a requirement for mushrooms to obtain food, they will surely survive.
