The Plasma membrane maintains the homeostasis throughout a cell because it filters what substances go in and out of the cell. If there is too much of a substance in a cell the plasma membrane quickly disposes it and when there is not enough of a substance in a cell the plasma membrane lets the substance in.
or this
A major role of the plasma membrane is transporting substances into and out of the cell. The plasma membrane is selectively permeable, allowing only certain substances to pass through. ... Cell transport helps cells maintain homeostasis by keeping conditions within normal ranges inside all of an organism's cells.

A sample of a meteorite has a density of 23 g/ml. It takes up a volume of 147 ml.
What is the mass of this unknown sample?
Answer:
3,381 grams
Explanation:
The problem can be solved by using the formula for "Density." The formula for density is: Density (ρ) = [tex]\frac{mass}{Volume}[/tex]
Now that we know the formula, we can get the formula for the "mass."
mass = ρ x VolumeThe given density above is 23 g/mL while the given volume is 147 mL. We have the values of the density and volume, thus, it is easy to solve the problem.
Let's solve.
mass = 23 g/mL x 147 mLmass = 3,381 gramsThe mass of the meteorite is 3,381 grams.

October 1, 2017 marks 27 years since the beginning of the Human Genome
Project. The goal of the group was to map the entire 3 billions bases and
80,000 genes in the human genome. On April 14, 2003, it was announced
that the goal was accomplished. Using this information, scientists have been
able to predict the risk of genetic diseases and understand the process of
inheritance. Which of the following statements best describes the process of
using the genetic code to produce polypeptides (proteins)?
Translation is used to produce a strand of RNA and proteins from a single strand of DNA.
O RNA produces a strand of DNA through transcription, then the DNA builds a protein molecule
through translation
O A single strand of DNA is used to make mRNA using translation, then the mRNA provides the
template for producing a protein through transcription
O A single strand of DNA is used to produce mRNA through transcription, then translation provides
the code for bonding amino acids to make a protein.
Answer:
The last one. A single strand of DNA is used to produce mRNA through transcription, then translation provides the code for bonding amino acids to make a protein.
Explanation:
Educated guess, but also. Translation is the process by which mRNA is decoded and translated to produce a polypeptide sequence, otherwise known as a protein. This method of synthesizing proteins is directed by the mRNA and accomplished with the help of a ribosome, a large complex of ribosomal RNAs (rRNAs) and proteins.
If the endoplasmic reticulum were removed from the cell, which organelle would not be able to function properly, and why? mitochondria, because they rely on the ER as an energy source ribosomes, because they receive proteins made by the ER Golgi apparatus, because it packages proteins received from the ER cytoplasm, because it relies on the ER for structural support
Answer:
Golgi apparatus, because it packages proteins received from the ER
Explanation:
The function of the endoplasmic reticulum is to produce proteins. It can be smooth or rough. The rough endoplasmic reticulum has ribosomes, which make the proteins.
The Golgi apparatus receives proteins from the endoplasmic reticulum and modifies and sorts them. They are then concentrated and packed into vesicles which are released out of the cell membrane.
If the endoplasmic reticulum is removed, proteins cannot be made and the Golgi apparatus would not be able to perform its job.
Hope that helps.
If the endoplasmic reticulum (ER) were removed from the cell, Golgi apparatus would not be able to function properly.
What is endoplasmic reticulum?"Endoplasmic Reticulum is a network of membranous tubules present within the cytoplasm of a eukaryotic cell."It is of two types- Smooth Endoplasmic Reticulum and Rough Endoplasmic Reticulum.It helps in calcium storage, protein synthesis and lipid metabolism.What is Golgi apparatus?It is also known as Golgi body or Golgi complex.It helps in transporting, modifying and packaging of proteins and lips lipids which are synthesized by Endoplasmic Reticulum.Hence, Golgi apparatus would not function properly if Endoplasmic Reticulum is removed.

Genotype ratio = 1GG:2Gg:1gg
Phenotype ratio = 3:1 (green ratio the other color)
4. Assuming that green (G) is dominant over the other color (g) as above:
homzygous green plant = GG; heterozygous green plant - Gg
GG x Gg
GG Gg GG Gg
Genotype ratio = 1GG:1Gg
Phenotype ratio = 100% green
5. Assuming that tall (T) is dominant over short (t)
Homzygous tall plant = TT
short plant = tt
TT x tt

Copper sulfide is found written as both CuS and Cu2S. Why are there two forms for writing this chemical formula?
SELECT AN ANSWER
This is an example of a combination reaction: CuS is the halfway stage, before the second copped atom joins the molecule.
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
This is a synthesis reaction and so the formula will continue changing until all the atoms have conglomerated.
One of the versions is a mistake, the correct form should be Cu2S.
Answer:
option 3
Explanation:
Copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+).
There are two forms for writing the chemical formula because copper is a transition metal with two possible ionic states (copper I, or 1+, and copper II, or 2+)
Copper is a transition metal with variable oxidation states. The oxidation states of copper is what determines the name of CuS and Cu₂S.
Now, we shall determine the oxidation states of copper in each compound.
For CuS:
CuS = 0
S = –2
Cu =?Cu + S = 0
Cu + (–2) = 0
Cu – 2 = 0
Collect like terms
Cu = 0 + 2
Cu = +2For Cu₂S:
Cu₂S = 0
S = –2
Cu =?2Cu + S = 0
2Cu + (–2) = 0
2Cu – 2 = 0
Collect like terms
2Cu = 0 + 2
Divide both side by 2
Cu = 2/2
Cu = +1From the calculations made above, we can see that copper has oxidation state of +2 in CuS and +1 in Cu₂S
Thus, we can conclude that Copper is a transition metal with two possible ionic states and this accounts for the different names of CuS and Cu₂S

What happens during Prophase I? You will need to think about what you learned during mitosis to fully answer the question.
DNA coils into chromosomes
Crossing over
Nuclear Membrane disappears
Chromosomes line up in the middle of the cell
Answer:
Crossing over
Explanation:
Prophase I is the first stage of meiosis I, it is the longest phase of meiosis. Crossing over (also known as recombination) can be defined as the process of exchange of genetic material between non-sister chromatids that occurs during Prophase I. Crossing over represents a critical source of genetic variation in offspring (the other one is the random orientation of the homologous chromosomes pairs). After crossing over, the resulting haploid (n) gametes aren't genetically identical to one another.

The cell cycle has a regular system of checks and balances that prevents damaged or mutated cells from proceeding to the next phase. One way an organism deals with the problems is to kill the damaged cell before it passes on the problem to its daughter cells. This is a normal process called apoptosis.
a. True
b. Fale
Answer:
A. True
Explanation:
Apoptosis is a normal cellular process in which the cell inherently programs the death of a mutated or damaged cell without affecting the healthy condition of the other surrounding cells by proliferating.
Apoptosis is a system of checks and balances that the cell uses to prevent damaged or mutated cells from proceeding to the next phase in the cell cycle. This curbs or prevent the damaged cell from passing on the problem to its daughter cells. Hence, according to this question, it is TRUE.

Which of the following best explains the endosymbiosis theory of how eukaryotic cells originated, as shown below? A.Eukaryotic cells developed from mutations in prokaryotic cells
B.Eukaryotic cells developed from organic compounds carried to Earth by debris from space
C.Eukaryotic cells originated from a combination of gases and heat in the atmosphere
D. Eukaryotic cells were originally large prokaryotic cells that absorbed smaller prokaryotic cells
Answer:I’m sure the answer is D
Explanation:
All eukaryotes evolved from prokaryotes and eventually developed into mitochondrial organelles.
The endosymbiotic theory represents that some of the organelles in eukaryotic cells were prokaryotic microbes at some time. As per the endosymbiosis theory the eukaryotic cells were at first large prokaryotic cells that absorbed smaller prokaryotic cells.
What is endosymbiosis?Endosymbiosis is the engulfing of the cell by another one to produce, over time, a coevolved relationship in which none of the cell could survive alone.
It is an evolutionary theory that guides the origin of eukaryotic cells by prokaryotes.
Eukaryotic cells were previously large prokaryotic cells that actually absorbed smaller prokaryotic cells
Thus, the correct option is D.
