Explanation:
The plant cell has a large central vacuole and creates a stronger exterior.
The plant cell has a rigid cell wall and the pressure from the central vacuoles causes the stiffness of the plant and animal cells do not have a cell wall therefore the boundary of the cell is weaker.
The plant cell is stronger because it has the chloroplast and causes a strong boundary that support the cell due to the glucose that is made from the process of photosynthesis.
Why do you think Flourine is able to pull the electron away from Lithium?
Answer:
Because of its high electronegativity.
Explanation:
Fluorine has ability to pull the electron from the lithium because of its high electronegativity.
We know that as we move from left to right in periodic table the number of valance electrons in an atom increase. The atomic size tend to decrease in same period of periodic table because the electrons are added with in the same shell. When the electron are added, at the same time protons are also added in the nucleus. The positive charge is going to increase and this charge is greater in effect than the charge of electrons. This effect lead to the greater nuclear attraction. The electrons are pull towards the nucleus and valance shell get closer to the nucleus. As a result of this greater nuclear attraction atomic radius decreases and electronegativity increases. AS lithium is present on left side of period 2 and fluorine is present on right side of same period. Fluorine is more electronegative while lithium is more electropositive thus fluorine pull the electron from lithium when they combine and form anion while lithium loses its valence electrons and form cation.
If you poured the fluids below into a container, which would sink to the bottom?
-water with a density of 1.0 g/cm3
-vegetable oil with a density of 0.91 g/cm3
-honey with a density of 1.36 g/cm3
-air with a density of 0.00013 g/cm3
Answer:
Honey > Water > oil > air
Explanation:
Heavy density will sink and less heavy density will float
So,
Density of honey is highest so, honey will sink
than,
Density of water is higher so, vegetable oil will float
Density of oil is higher so, air will float
Honey > Water > oil > air

How many water (H2O) molecules could you line up end to end in a nanometer?
Answer:Molecules have size and different molecules are different sizes. When talking about the size of a molecule, most scientists will mention its molecular weight. That is the total weight of all of the atoms in the molecule. So water, which is made up of two hydrogen atoms (1 atomic mass unit each) and one oxygen atom (16 atomic mass units) has a molecular weight of 18 (well, 18.01528 to be exact). Glucose has a molecular weight of 180. DNA, which is very long, can have a molecular weight that is around 1010 (about the weight of one human chromosome).

why virus is imortal?
Answer:
Strictly speaking, viruses can't die, for the simple reason that they aren't alive in the first place. Although they contain genetic instructions in the form of DNA (or the related molecule, RNA), viruses can't thrive independently. Instead, they must invade a host organism and hijack its genetic instructions.
Explanation:
Answer:
A flu is a virus and the reason that you have to get flu shots every year is because every time a virus enters a host it is mutated by the antibodies, cells and biology of that host, so it can be passed on to another host who may not be immune to every part of this NEW virus.
Explanation:

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle
Answer:
competitive
Explanation:
example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others
The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.
What is the competitive exclusion principle?It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.
In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.
Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.

where are neutron founded?
Answer:
By 1920, physicists knew that most of the mass of the atom was located in a nucleus at its center, and that this central core contained protons. In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Explanation:
Answer:
In May 1932 James Chadwick announced that the core also contained a new uncharged particle, which he called the neutron. Chadwick was born in1891 in Manchester, England.
Explanation:
Neutrons come from fusion. Let's say you push two protons together enough for them to "touch", specifically for them to experience attraction from the strong nuclear force that is stronger than electrostatic repulsion.You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus. During radioactive decay, they may be knocked out of there.
state 4 ways by which through which a soil is depleted
Answer:
Explanation:
Leaching – Plant nutrients are lost beyond the reach of plant roots. Usually caused by excessive rainfall washing nutrients deep down into sub-soil beyond new roots reach.
Soil erosion – Top soil is lost by the agent of erosion e.g. wind, water.
Monocropping – This utilizes only specific nutrients from a particular zone making it exhausted. -It also causes accumulation of certain pests and diseases.
Continuous cropping –This continuously exhaust the fertility of land unless the the land if fallowed.
Change of soil PH -Use of either acidic or basic fertilizers affect soil pH and Consequently the presence of micro-organisms hence soil fertility affected.
Burning of vegetations –Destroys organic matter and soil structure. Nutrients are lost and soil exposed to erosion.
Accumulation of salts – Common in waterlogged areas and semi-arid areas in which poor drainage causes evaporation during the dry periods, making the soil saline.
