Kate and Sam are using a scanning electron microscope to study photosynthesis in algae, and the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.
What are the benefits of using a microscope?The microscope gives a better view of the smaller things, and there are different types of microscopes, such as the light microscope, the electron microscope, etc., and other high-quality microscopes that are helpful for the better viewing of the samples. The light microscope has a lower magnification range than the electron microscope, and the species can be better viewed in the electron microscope. Depending on the application, different microscopes should be used, and photosynthesis can be seen better in a scanning microscope than in a light microscope.
Hence, the benefit of using this type of microscope rather than a light microscope is that the scanning microscope gives clearer details of the process.

a man is twice as old as his son.Five years ago the ratio of their ages was 9:4.Find the sum of their ages
Answer:
75years
Explanation:
Let the Father's age be represented by 2x
Let the Son's age be represented by x
Five years ago;
Man's age will be = 2x - 5
Son's age will be = x - 5
If the ratio of their ages five years ago was 9:4, then;
2x - 5/x-5 = 9/4
4(2x - 5) = 9(x - 5)
8x - 20 = 9x - 45
- Collect like terms
-20 + 45 = 9x - 8x
25 = x
Hence, the son's age = 25 years
If x = 25, the father's age (2x) will be 2 × 25 = 50years
The sum of their ages will be = 25years + 50years = 75years

Suggest what might happen if cells grow and reproduce in an environment where no cholesterol is available.
Cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis
Explanation:
If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.
What is plasma membrane?Cell membrane has been defined as a wall that differentiate and protect the inner structure of the cell from the outer environment. The main function of the cell membrane has to keep away the toxic material out of the cell. The cell membrane contain the channels as well as receptors that gives permission to only selective permeable membrane to enter into the cell.
Cells must maintain homeostasis to survive. To do this cells use various processes. One process keeps the right amount of water inside the cell. A cell takes in the same amount of water as it looses describe that it is maintaining homeostasis by keeping it's water concentration level.
Therefore, If cells grow and reproduce in an environment where no cholesterol is available than cell walls provide support and protection for plant cells and the plasma membrane maintain homeostasis.

An egg, a model of a cell, is placed in a concentrated sugar solution (hypertonic) for 24 hours.
What will happen to the egg? The egg will
1. lose mass and shrink in size
2. gain mass and increase in size.
3. stay the same mass and size.
Answer:
gain mass and increase in size
Answer:
1. lose mass and shrink in size
Explanation
the egg is a more dilute solution that the one it is placed in. Through osmosis it will lose water until both solution(the inside and outside of the egg) have roughly the same concentrations. Losing water will cause it to shrink.

How is it possible that the reactants and products for both chemical equations have the same quantity of carbon, hydrogen, and oxygen atoms, yet the reactants and products are different molecules?
Answer:
Yes, this may be a little confusing when taking a first glance at the chemical equation.
Explanation:
You see, the whole process of balancing an equation is to make sure the reactants and products have the same amount of mass/atoms.
With that being said, the products to appear to be different after going through the chemical change. this is because of what was happening through that process. But, all of these atoms are still within the final product.
For example, if you take water in a container, one with a lid and one without a lid, then you heat up both containers of water, the container that has the lid open will seem like the water is gone, that the atoms are not the same. Actually, if we take a look at the closed container, all of that gas that was formed from the water still has the same amount of atoms contained in it. As for the open lid container, the atoms are all there, but some of them was just released into the air outside of the jar, making it seem like there is less.

The study of chemicals is called chemistry.
It is possible to have different chemical properties but the same number of elements present in the reactant and the product.
According to the law of mass of conservation of the mass. it states that the number of elements present in the reactant and the product will always remain the same.
Hence, according to this law, the mass and the quantity of the element are the same but the bonds and the arrangement of the elements are different which causes different chemical behavior.
Hence, it is possible.

Which best describes the importance of carbohydrates to organisms?
A. Carbohydrates provide an additional source for amino acids.
B.Carbohydrates provide an immediate energy source
C. Carbohydrates provide permanent storage for genetic information.
D.Carbohydrates provide storage for water molecules
Answer:
[tex]\boxed {\boxed {\sf B. \ Carbohydrates \ provide \ an \ immediate \ energy \ source}}[/tex]
Explanation:
Carbohydrates are important because they provide the body with energy. It's essential to consume the correct amount of carbohydrates for your body, but make sure they are healthy (examples: whole grain, squash, sweet potatoes, beans)
Carbohydrates are easy for the body to break down. The body will digest these first into simple sugars, like glucose. The glucose is then used in cellular respiration to produce ATP or energy.
Therefore, carbohydrates can quickly provide energy for the body. The best answer choice is B.
Answer:
Carbohydrates provide energy to organisms.
Explanation:
I'm 100% sure because Carbohydrates can also be defined chemically as neutral compounds of carbon, hydrogen and oxygen. Carbohydrates come in simple forms such as sugars and in complex forms such as starches and fiber. The body breaks down most sugars and starches into glucose, a simple sugar that the body can use to feed its cells

Explain what information about populations cannot be gathered when looking solely at population pyramid data.
Answer:
Hi there, so the population pyramid visualizes two variables which are sex and age but it doesn't tell us the actual number of population within a region it only collects the sex (female and males) and the ages (ranging from infant to elderly).
So the only thing that population pyramid data can't collect is the actual population in number.
Hope this helped :)
The population pyramid, therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex (females and men) (ranging from infant to elderly).
What is the population?As a result, the only thing the population pyramid data cannot measure is the size of the population.
Population pyramids do have certain restrictions, though. It is typically impossible to tell the relative contributions of various demographic processes on population age structure since they simply provide the size of each age-sex group in the population.
Therefore, depicts the two factors of sex and age, but it is silent on the region's actual population size instead, it simply gathers data on ages and sex.
