Answer:
The correct answer is given as follows:
Explanation:
Mean is the average in a common or informal way. It can be calculated by Adding the total numbers up and divide them by the total number of values in the set.
In this case: 37 is the mean value that can be calculated by:
adding all the values: 36.7+36.8+36.9+37+37.1+37.2+37.3 = 259
Number of sets = 7
then mean = 259/7
= 37
Thus, the mean can be calculated by total value divided by the number of sets

Dave was observing two types of cells mounted on two different microscopic slides 'A' and 'B'
under the microscope. When he had observed the slide 'A' he noticed a large vacant space in the
cells and a dense round body located at one side of the cell. When he had observed the slide 'B',
there was no vacant space in the cell and he noticed a dense round body in the centre of the cell.
a) Identify the type of cell 'A' and 'B'.
b) Name the round dense structure seen in the cell.
c) Write the function of the round dense structure that he observed in the cell.
ans this please

Answers
Answer:
The correct answer is -
a) A plant cell B animal cell
b) nucleus
C) Vacuole
Explanation:
In plant cells, there is a large vacant space present in the center which is actually a vacuole that plays role in various types such as nutrients storage, water balance. In plant cells, a dense round structure present at one side of the cell known as the nucleus.
In animal cells, the vacuoles are absent or very small however the round dense structure of the nucleus is present in the center of the cell. Thus, the correct answer is -
a) A plant cell B animal cell
b) nucleus
C) Vacuole

ASAP! 30 POINTS!!! Write a persuasive paragraph that argues either for or against wind energy. Be sure to include both the pros and cons of wind energy in your paragraph. Use all data, evidence and examples that you are aware of in your paragraph.

Explanation:
ᴍᴀʀᴋ ᴀs ʙʀᴀɪɴʟɪᴇsᴛ
Answer:
Wind energy is one of the most commonly used types of renewable energy. and also happens to be one of our fastest-growing sources of electricity. However, while there are a number of environmental benefits to using wind energy, there are some downsides. On the pros side, wind is a clean, renewable energy source, and is one of the most cost-effective sources for electricity. On the cons side, wind turbines can be noisy and unappealing aesthetically, and can sometimes adversely impact the physical environment around them. Similar to solar power, wind power is also intermittent, meaning that turbines are reliant on weather and therefore aren’t capable of generating electricity 24/7. Unlike coal, natural gas, or oil, generating electricity from wind doesn’t result in greenhouse gas emissions. While there are some environmental considerations that come with building large wind farms, once operational, wind turbines themselves don’t require burning any fossil fuels to operate.
Additionally, wind energy is completely renewable and will never run out. In opposition to traditional fossil fuels resources that replenish very slowly, wind naturally occurs in our atmosphere, and we don’t have to worry about supply issues in the future.
As far as upfront costs go, wind farms or individual turbines can be expensive to install. However, once up and running, operating costs are relatively low; their fuel (wind) is free, and the turbines don’t require too much maintenance over the course of their lifetime.
A wind turbine’s effectiveness in generating electricity depends on the weather; thus, it can be difficult to predict exactly how much electricity a wind turbine will generate over time. If wind speeds are too low on any given day, the turbine’s rotor won’t spin.
This means wind energy isn’t always available for dispatch in times of peak electricity demand. In order to use wind energy exclusively, wind turbines need to be paired with some sort of energy storage technology.
One of the biggest downsides of wind energy is the noise and visual pollution. Wind turbines can be noisy when operating, as a result of both the mechanical operation and the wind vortex that’s created when the blades are rotating. Additionally, because wind turbines need to be built up high enough to capture a good amount of wind, the turbines can often interrupt otherwise scenic landscapes, such as mountain ranges, lakes, oceans, and more.

Answers
Answer:
Friction and gravity are at work in each picture. Explain how each are at work and how they work together. Balanced forces - Two or more opposite forces are balanced forces if their effects cancel each other and do not cause a change in an object's motion.
Explanation:
Balanced forces are equal and opposite forces that act on the same object. That's why they cancel out. Action-reaction forces are equal and opposite forces that act on different objects, so they don't cancel out. In fact, they often result in motion.

The statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others. So, the correct option is D.
What do you mean by Natural selection?Natural selection is the process through which populations of living organisms adapt and change their needs as per nature.
The given statement gives the idea of adaptation rather than natural selection. Natural selection gives the idea of competing for limited resources. Natural selection always leads to the most favorable types of variation that an individual possess.
Therefore, the statement which is not a principle of natural selection is, in every population, adaptations allow some organisms to survive and reproduce better than others.
