Answer:
Explanation:In particular, eukaryotic cells divide using the processes of mitosis and meiosis. Mitosis is common to all eukaryotes; during this process, a parent cell splits into two genetically identical daughter cells, each of which contains the same number of chromosomes as the parent cell.
A parent cell is the cell that divides during cell division to produce two daughter cells. The two daughter cells produced during mitosis share the same genetic makeup as the parent cell. In meiosis, the daughter cells have half as many chromosomes as the parent cell and a distinct genetic makeup.
What is parent cell ?A parent cell that is a progenitor of other cells or the first in a line of growing cells, as well as a cell that divides to produce two or more daughter cells.
The cell that divides into two daughter cells during cell division is referred to as the mother or parent cell. The mother cell's genetic makeup is carried over into the two daughter cells created during mitosis.
An organism's reproductive cells are called gametes. They are additionally known as sex cells. Male gametes are referred to as sperm, whereas female gametes are referred to as ova or egg cells. Each haploid cell that makes up a gamete has one copy of each chromosome.
Thus, A parent cell is the cell that divides during cell division to produce two daughter cells.

What causes the electrons to move and form static electricity?
moist air
dry air
friction
Answer:
friction
Explanation:
The rubbing of certain materials against one another can transfer negative charges, or electrons.
The friction generating between the surface of two objects causes the electrons to move from one body to the other and form static electricity. Hence, option c is correct.
What is static electricity ?Static electricity is the flow of electrons that occurs due to the temporary polarization of two bodies. When a conducting surface rub on other surface, they gets electrons by frictional force.
These free flow of electrons make them negatively charged. When this negatively charged body comes in contact with a non conducting surface they latter gets polarized by the electrons of negatively charged body.
The positive charges of the nonconducting surface gets attracted to the negative body and the electrons flow from the negatively charged body to the partially polarized positive body. This is called static electricity.

Which one would charge faster?
Magnesium is a metal with two electrons in its outermost energy level. When it becomes an ion, what happens to its valence electrons? What happens to its charge?
Answer:The answer to your question is Mg loses its valence electrons and acquire a positive charge (Mg⁺²).
Explanation:
Answer:
When it becomes an ion, it donates its valence electrons and becomes positively charged. The positively charged ion would be Mg²⁺ because it loses two electrons. It would have 12 protons and 10 electrons.

What are three ways that synthetic materials benefit human society?
Answer:
The benefits in synthetics are many, they have properties that we can't find in nature, they allow us to make things stronger, lighter, more fuel-efficient, shiner, longer lasting. And at the same time, we do add to the pollution of our world, affect the health of animals and humans, and requires energy to make.
Explanation:
Synthetic materials, also known as man-made or artificial materials, have made significant contributions to human society. Like Improved Performance and Durability, Expanded Range of Applications, etc.
Here are three ways in which synthetic materials benefit us:
Synthetic materials often possess superior properties compared to natural materials, such as increased strength, durability, and resistance to wear and tear.
Expanded Range of Applications: Synthetic materials have opened up new possibilities by offering characteristics that may not be readily available in nature.
Resource Conservation and Environmental Benefits: Synthetic materials can help conserve natural resources by providing alternatives to scarce or unsustainable materials.
Thus, while synthetic materials have numerous benefits, it is essential to consider their environmental impact throughout their lifecycle, including disposal and potential hazards.

Explanation:
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.
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---------------------------
