There are many differences between a plant cell and animal cell

In animal cell glycogen is the energy storage carbohydrate.

In plant cell starch is the energy storage carbohydrate

so if we notice the presence of starch in a cell it tells that it must be a plant cell.

Water has a density of 1 g/cc. If you have 1 cc of water, how much mass does it contain?

rewona [7]

Water has a density of 1 g/cc. If you have 1 cc of water, then the mass it contains would be 1 g. Density is a physical property of a substance that represents the mass of that substance per unit volume. It is a property that can be used to describe a substance. Hope this answers the question. Have a nice day.

A 52.0 g of Copper (specific heat=0.0923cal/gC) at 25.0C is warmed by the addition of 299 calories of energy. find the final tem

Leto [7]

Answer : The final temperature of the copper is, $87.29^oC$

Solution :

Formula used :

$Q=m\times c\times \Delta T=m\times c\times (T_{final}-T_{initial})$

where,

Q = heat gained = 299 cal

m = mass of copper = 52 g

c = specific heat of copper = $0.0923cal/g^oC$

$\Delta T=\text{Change in temperature}$

$T_{final}$ = final temperature = ?

$T_{initial}$ = initial temperature = $25^oC$

Now put all the given values in the above formula, we get the final temperature of copper.

$299cal=52g\times 0.0923cal/g^oC\times (T_{final}-25^oC)$

$T_{final}=87.29^oC$

Therefore, the final temperature of the copper is, $87.29^oC$

Explain on any two materials that you would expect to use for the wheelchair (both back support and

Ugo [173]

Answer:

In the backrest use materials where it is easy to clean and where they do not absorb fluids, in this way it would be cooler, such as an ecological leather simulator.

And in the armrest as well, but in both areas we must not rule out that if or if it should have even a minimum of padded surface so that the patient or the person who spends most of the day in the wheelchair does not suffer from joint pain.

Explanation:

Some wheelchair factories also implement modern chairs where they are made of stainless steel structures lined with padded material with perforated fabrics that allow breathing and aeration of body areas that have contact with the fabric.

Mr. Jones, the science teacher, tells his students that energy cannot be created; it must be captured from the environment. He i

taurus [48]

The law of conservation of energy or first law of thermodynamics

Explanation:

From the context we can infer that Mr. Jones was describing the law of conservation of energy.

According to the law of conservation of energy:

"energy is not created nor destroyed by can be transformed from one form to another" .

The captured energy is a form of energy and it is change into other forms in the ecosystem.

Energy is initially captured in the ecosystem by plants.
