Answers
The Zinc carbon batteries, are a reliable source of power for appliances that consume little energy. Some examples are: remote controls for televisions, clocks, and smoke detectors. A reason that you should use the Zinc carbon batteries is for, the low energy consumption. This will lead to being able to use the appliances for a longer time for the same money.
The difference between the batteries is the capacity. Because of composition, an alkaline battery, delivers more energy than a zinc carbon battery.
The only downside is that, both batteries need to be used in different appliances.

what do you mean by cohesion ?cohesion is an attractive force of measure where molecules are stick to each other and it is caused by cohesive force between like molecules.
It is an intrinsic property of a molecule, derived by its shape, structure, and electric charge distribution.
When cohesive molecules are become closer to each other, the electrical attraction between these molecule holds them together.
This forces are responsible for surface tension. For example mercury is a cohesive substance, strongly attracted to each other, bead together, sticks to itself when it flows.
When cohesion and adhesion combinedly work, it will lead to capillary action.
Hence, when water climbs up the interior of a thin glass tube or the stem of a plant, Cohesion holds the water together and adhesion helps the water molecules stick to glass.

I have 11 protons, which element am I?
A. Silicon
B. Fluorine
C. Argon
D. Sodium
Answers
Answer:
D. Sodium
Explanation:
We know that the atomic number of sodium is 11. This tells us that sodium has 11 protons and because it is neutral it has 11 electrons. The mass number of an element tells us the number of protons AND neutrons in an atom (the two particles that have a measurable mass).

Scientists have been studying four populations in one area of the Atlantic Ocean. In this area, both tuna and dolphins eat squid, and squid eat herring (a type of fish).
The data shows that recently the tuna population increased. How will the increase in the tuna population affect the other populations? Be sure to explain whether the dolphin population, the squid population, and the herring population will change, and why.
Answers
Answer:
the squid population could decrease, because the tuna population is increasing and they would eat more squid, so the dolphin population would also decrease because there would be less squid to eat, and because there are less squid the herring population would increase.
In trophic webs, there is an equilibrium between species until a change occurs. The increase in tuna's population causes a decrease in dolphins' and squids' populations, and an increase in herring's one.
------------------------
To answer this question, let us first review some theoretical framework.
The trophic web is a relationship process between different organisms, through which occurs transference of energy.
The ones placed at lower levels pass energy to the ones at the higher levels.
Organisms at each level feed on the preceding one and become food for the next one.
The first link corresponds to a producer organism -autotroph-. The following links are the consumers -heterotrophs-: herbivores and carnivores. The last links are the decomposers that degrade organic matter from dead organisms.As it is a web, all organisms are equilibrated until a change occurs.
When the change affects any of the involved links, there can be a cascade effect on the web.
A change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.
Also, when two or more species are competing for the same source of food, a change in any of the population sizes will affect the other ones.
Now, let us analyze the exposed example.
We know that,
tuna and dolphins eat squid, squid eat herring.We need to figure out what is the cascade effect caused by the increase in the tuna population.
Tuna and DolphinsWe know that tuna and dolphins compete for food items -squids-.
An increase in the number of tuna individuals means a higher competition pressure for dolphins.
The more tuna there are, the more squids they eat, and the less food available there is for dolphins.
Since there are not enough squids for dolphins, their population decreases in size.
Dolphins are negatively affected by tuna's increase.
**** Tuna population increases ⇒ Dolphins population decreases ****
Tuna and Squids
Tuna applies a significant predation pressure on squids, which are their main source of food.
The more tuna there are, the more squids they eat.
Squids probably can not reach sexual maturity or do not get to successfully reproduce, because they are eaten by tuna.
So squids population is negatively affected by the tuna population increase.
**** Tuna population increases ⇒ Tuna population decreases. ****
Herring and SquidsSince squids feed on herring, any change in squids' population size affects herrings directly.
When the squids' population decreases in size, the herring population increases. More fishes get to survive and successfully reproduce.
The predation pressure of squids on herring decreases.
The herring population is positively affected by the squids' population decrease.
*** Squids population decreases ⇒ Herring population increases. ***
Summing up, the cascade effect is as follows,
Tuna population increasesDolphin population decreasesSquids population decreasesHerring population increases---------------------------

PREDICT: Which do you think would be the most adhesive and least adhesive to wax paper and why do you think this?
A) oil
B) Isopropyl alcohol
C) tap water
D) soapy water
Answers
Answer:
Tap water would be the least adhesive to wax paper.
Oil would be the most adhesive
Explanation:
If you get wax paper and water right now, it will repel the water. Putting wax on anything makes it water repellent. I don't know how but this is just my prediction.
I feel like oil would be the most adhesive because oil repels water, so does wax paper. So I'd predict oil would hold onto wax paper the most.
Hope this helps!
