1- Reactants (H = 2, O = 2)
Products (H = 2, O = 0)
2- Reactants (P = 4, O = 2)
Products (P = 2, O = 3)

So basically if it was H20, then there is 2 Hydrogen because the two is in front of the H and there isn’t a 2 in front of Oxygen.
However if it was H2O2, then there is two hydrogen and two oxygen because there is a two on both of the symbols which indicates how much reactants/products there is.

Hope this helps!

Let’s say A plant cell, normally diploid, completely screws up mitosis during metaphase and pulls full copies of all chromosomes
andrezito [222]

Answer:

4N

Explanation:

Mitosis is the process whereby a cell duplicates or produces another identical copy of itself. The mitotic process, which occurs in four main stages produces two daughter cells that are genetically identical to the parent cell. For example, a diploid organism (2n) will produce two daughter cells with 2n from mitosis.

However, in a case whereby a plant cell (A) screws up mitosis during metaphase and pulls full copies of all chromosomes to one side. This would result in one daughter cell having 4n or tetraploid number of chromosomes. Ideally, mitosis separates the chromosomes equally into the two daughter cells to have 2n each. If one cell has all chromosomes, it means that cell will have all the 4n.

For example, in a diploid human cell with 46 chromosomes (2n). Mitosis should occur in such a way that each daughter cell will have a diploid 46 number of chromosome (2n). However, if all the chromosome ends up in one cell during mitosis, that cell will have 92chromosomes, which is 4n or tetraploidy.

Linear equations are used to represent relations that have constant rates

The linear regression equation that models the data in this table is \^y = 2.40476x + 0.33333

<h3>Regression equation using a graphing calculator</h3>

To calculate the regression equation, we make use of a graphing calculator.

Using the graphing calculator, we have the following data:

  • Sum of X = 28
  • Sum of Y = 70
  • Mean X = 3.5
  • Mean Y = 8.75
  • Sum of squares (SSX) = 42
  • Sum of products (SP) = 101
<h3 /><h3>Formulating the regression equation</h3>

The regression equation is represented as:

\^y = b\^x + a

Where:

b = \frac{SP}{SSX} and a = MY - bMX

So, we have:

b = \frac{101}{42}

b = 2.40476

Also, we have:

a = MY - bMX

a= 8.75 - 2.4\times 3.5

a= 0.33333

Hence, the linear regression equation is:

\^y = 2.40476x + 0.33333

Members of the Deinococcus genus present an interesting conundrum to scientists who try to classify them as either gram-positive
AURORKA [14]

Answer:

Explanation:

Bacteria can be classified traditionally into two broad categories according to their cell wall, which are Gram-positive bacteria and Gram-negitive bacteria.

Gram-positive bacteria are bacteria that produce a positive result when Gram stain test is performed. It takes up the crystal violet stain of the test, and then show a purple-coloured appearance when seen through an optical microscope. This is as a result of the thick "peptidoglycan" layer in the bacterial cell wall which retains the stain used in the cell after washing it away from the rest of the sample.

Gram-negative bacteria after the decolorization don't retain the violet stain,the outer membrane of gram-negative cells is degraded by the alcohol.The peptidoglycan layer is positioned and between the membrane and a bacterial outer membrane, causing them to take up the counterstain and made appear red or pink.

Therefore, Deinococcus is one genus of the bacterial phylum that have resistant to environmental hazards. They posses thick cell walls that give them Gram-positive stains, but they also posess second membrane that made them them closer in structure to Gram-negative bacteria, which present an interesting conundrum to scientists who try to classify them as either gram-positive or gram-negative.

As an analogy to gene expression in eukaryotes, let's compare it to the process of cooking recipes from a library of cookbooks.
scoundrel [369]
Two major steps are needed to obtain a protein from a gene. Transcription makes it possible to obtain a copy of the gene present on the chromosome, in the form of a messenger RNA (mRNA). Translation is the stage during which this mRNA is read by the ribosome to obtain a protein.
DNA replication is associated with photocopy because replication will give an identical copy of the cell DNA.
Transcription is associated with book printing because in transcription the genetic information will be transferred to another platform (RNA)
Nucleus in a Library since this is where the "book printing" occurs, and where the books (DNA) are
DNA is the book, where all the information are
RNA transcript is the photocopy
Translation is the cooking since it is the protein synthesis
Proteins/polypeptide is the cooking objective, so it is the prepared dish
RNA polymerase is the Xerox machine, it will copy the information in the DNA to RNA transcript
Ribosomes is the cooks, because this is where translation occurs
Activator protein are the bookmarks because it choose wich part of DNA it has to be transcript.

I need someone to do a essay for me the information about the essay is in the picture
DedPeter [7]

Answer:

I'm sorry but you should do it on your own because if you don't you won't learn the way you should and plus that is cheating.
