Explanation:
It is very difficult to add or remove electrons from an atom that has eight electrons in its outer shell.
True
False
Explanation:
Electrons are typically removed from the valence shells, which are the highest s and p orbitals. Also, Hund's rule still applies here, but backwards. Electrons will be removed from their orbitals until all of them are unpaired, and then the unpaired ones will be removed.
May be true because velence shell is the outermost shell which can be removed.

Over 99.9% of the solar system is composed of hydrogen and helium. How does this help to explain the size differences between the terrestrial planets and the gas giants?
Explanation:
Gas giants/Jovian planets are also called the outer planets, they are made of gases, they are large and less dense, more moons. Terrestrial/Rocky planets are also called the inner planets. They are made of rocky surface, denser than Jovians, and small, little or no moons.
The information about the composition of solar system has great significance in providing data about size between the terrestrial planets and the gas giants planets.
The size differences occur between the terrestrial planets and the gas giants due to the presence of different concentration of gases in their compositions. Gas giants planets are also called the outer planets which are made up of gases.
They are large in size but having less density and more moons while on the other hand, terrestrial planets are made of rocky surface. They are also called the inner planets. They are more denser than gas giant planets, small in size and less or no moons so we can conclude that there is a great size differences between the terrestrial planets and the gas giants.

According to kepler's second law of motion, which statement describes the area swept out by a line between a planet and the sun ??
A. It is constant for equal times
B. It increases as the planet moves away from the sun
C. It is constant if the planet moves at a constant speed
D. It increases as the planet approachas the sun
It is constant over equal periods of time, in accordance with Kepler's second law of motion. The right response is a.
It is constant if the planet moves at a constant speed. Option C
Describe Kepler's law.?The orbits of planets around the Sun are described by Johannes Kepler's laws of planetary motion, which were published between 1609 and 1619.
Kepler's second rule of planetary motion gives an explanation for the speed of a planet in an elliptical orbit around the Sun.
It asserts that similar areas are moved in equal lengths of time along a line drawn between the Sun and the planet.
As a consequence, the planet moves faster as it gets closer to the Sun and slower as it moves further away.
The transition from geocentrism to heliocentrism was ushered in by Kepler's laws of planetary motion.
Together with Earth, they provide the first quantifiable connection between the planets. Additionally, they depict a period when the key issues of the day were evolving.

Which of the following allows water to move much faster across cell membranes? A) the sodium-potassium pump B) ATP C) peripheral proteins D) aquaporins
Answer:
D
Explanation:
I believe the answer would be aquaporins
Aquaporins efficiently speed up the total rate of water diffusion across the cell membrane due to the slow diffusion of water through the lipid bilayer, hence option D is correct.
What are aquaporins?Aquaporins (AQP) are essential membrane proteins that act as conduits for the passage of water and, occasionally, tiny solutes.
The Na+ K+ pump is an electrogenic transmembrane ATPase that was initially identified in 1957. It is located on the cytosolic side of the cell's outer plasma membrane. For every ATP, the Na+ K+ ATPase pumps 3 Na+ out of the cell and 2K+ into the cell.
Therefore, animals, plants, and microorganisms all have them preserved. Every aquaporin molecule has a pore in the middle, according to structural investigations of the molecules.

PLEASE HELP ME IF YOU DONE THIS BEFORE Part 1: Introduction
Title
Title your lab report with a few words that
summarize the lab investigation
Purpose
The lab report should begin with one or two
sentences that state the purpose of the
investigation what you want to see, practice, loam
about, or test. The purpose statement answers the
question "What am I trying to find out by doing this
experiment?"
The three most common types of labs are:
inquiry labs, in which you measure how
changing one variable affects another variable
discovery labs, in which you observe a scientific
phenomenon, perhaps for the first time.
forensic labs, in which you gather and analyze
data as evidence to build an argument in
response to a question, as in a court case,
All three types of labs give you an opportunity to
learn important scientific skills and concepts.
Question
At its core, science is about inquiry, or the act of
asking questions and seeking answers. Most labs
begin as the result of a question, which is why the
introduction of your lab report should include a
question. For example, suppose you notice that you
seem to play basketball better at the court in one
park than in another. After conducting research, you
realize that one of the surfaces of the court at the
park is different from that of your driveway. As a
result, you might formulate the scientific question
"What effect does the court surface have on the
height that the basketball bounces?" To answer this
question scientifically, you could perform several
experiments and gather data,
Hypothesis (or Prediction)
A hypothesis is an initial answer to a question, a
possible explanation or expectation based on prior
knowledge or research. Before starting most lábs,
you will formulate a hypothesis. It should be listed in
the introduction of your tab report
A good scientific hypothesis states conditions,
expected results, and possible reasons for those
results, For example, you could respond to the
basketball question with a hypothesis like "If the
court surface is smooth concreto, as the park's
court is, then the basketball will bounce higher,
because smooth surfaces have better contact with
the ball." Like this hypothesis, hypotheses are often
structured using the format "il then, because
which is described below.
The "it' portion of the hypothesis describes
something that you will change in the experiment
• The "then" portion of the hypothesis describes
what you think will happen as a result of that
change
• The "because" portion of the hypothesis
describes the ason why you think that change
will occur
In other laboratory activities you will be asked to
make a prediction. You will conduct background
research, then predict the outcome of a known
scientific process
Special Note about inquiry Labs
For inquiry labs, questions are generally
written in the form of "What is the effect of X on
Y?" Hypotheses will generally be in the form of
X [describe how you will change X during the
experiment), then Y will predict how y will
change in response), because give your
reason." In many inquiry labs the variables
lend themselves to a scatterplot (X-Y plot)
For anyone else who needs help just write an essay on what ionic bonds are. Then write what covalent bonds are. Then write the difference between them. It’s better than getting in trouble for using someone else’s work.
The student guide made it very confusing as if you were doing a project but it’s not, it’s just an essay.
Answer:
Was gonna use some links but {insert anger} brainly doesn't allow it.
Explanation:
There are primarily two forms of bonding that an atom can participate in: Covalent and Ionic. Covalent bonding involves the sharing of electrons between two or more atoms. Ionic bonds form when two or more ions come together and are held together by charge differences.

A solution is a chemical reaction?
Answer:
False
Explanation:
A solution does not have to be a chemical reaction. Salt and water is a perfect example. Even though salt will dissolve in water, there is no chemical reaction going on. Salt remains salt and water remains water. The salt can easily be recovered by evaporating off the water.
Some solutions can be a chemical reactions but not all have to be.
Stem cells are used to treat some human diseases.
Stem cells can be collected from early embryos. These stem cells have not begun to
differentiate, so they could be used to produce any kind of cell, tissue or organ. The
use of embryonic stem cells to treat human diseases is new and for some diseases,
trials on patients are happening now.
Stem cells can also be collected from adult bone marrow. The operation is simple
but may be painful. Stem cells in bone marrow mainly differentiate to form blood
cells. These stem cells have been used successfully for many years to treat some
kinds of blood disease. Recently there have been trials of other types of stem cell
from bone marrow. These stem cells are used to treat diseases such as heart
disease
Evaluate the use of stem cells from embryos or from adult bone marrow for treating
human diseases

What's the definition of epista
sis
Epistasis is genetic phenomenon that is defined by an interection of genetic variation loci
Answer:
(Hope this helps can I pls have brainlist (crown)☺️)
Explanation:
The interplay of genes that determines phenotype is known as epistasis. Genes may either hide each other, making one "dominant," or they can mix to create a new characteristic. It's the conditional link between two genes that can determine a single phenotype for certain features.
Epistasis is a term used in genetics to describe the interaction of genes at two or more loci, as a consequence of which the gene's impact is influenced by the presence of one or more modifier genes. One gene or allele in the interaction is obscuring the phenotypic expression of the other genes or alleles. Epistatic refers to the gene or allele that masks the impact. The other gene(s) or allele(s) being masked, on the other hand, is/are referred to as hypostatic. Epistasis can be dominant or recessive. The fur colour of Labrador retrievers, which is a polygenic feature, is an example of epistasis. Its fur colour is determined by the interaction of two genes.
