A chromosome is a cellular DNA molecule that typically encodes thousands of genes. In order for the information encoded within a specific gene to be transcribed to make RNA, RNA polymerase begins to transcribe the DNA, using one DNA strand as a template to make a complementary RNA molecule that is later used for protein synthesis during translation. A scientist is studying two mutant bacterial strains that do not produce a functional form of amylase, an enzyme that the organisms use to break down starch polymers. The scientist is using a third bacterial strain capable of normal amylase production (called the wild type) for comparison. Upon sequence analysis of the DNA region around and including the amylase gene in all three bacterial strains, the scientist locates the mutations as shown. Which statement BEST explains how these mutations affect gene expression and amylase enzyme functionality in the mutant bacterial strains?

A. Only mutant #1 transcribes the amylase gene and translate the resulting mRNA, but the resulting enzyme is non-functional

B. Only mutant #2 transcribes the amylase gene and translates the resulting mRNA, but resulting enzyme is non functional

C. Neither mutant #1 nor mutant #2 transcribes the amylase gene nor complete translation, so neither make functional enzymes

D. Both mutant #1 and mutant #2 transcribe the amylase gene and translate the resulting mRNA, but both resulting enzymes are non- functional.

Explanation:

Metabolic processes expell heat to work properly.

because it is movement of muscle tissue, which creates heat while in movement, this is called the metabolic cycle....

Answer:

mass doubled makes KE twice as large

velocity doubled makes KE 4 times as large

Explanation:

Try it with an example

m = 4

v = 8

KE = 1/2 m * v^2

KE = 1/2*4 * 8^2

KE = 1/2 * 4 * 64

KE = 128

Now double the mass

m  = 8

v = 8

KE = 1/2 8 * 8^2

KE = 1/2 8 * 64

KE = 4 * 64

KE = 256 double what it started out as.

Now do it again.

m = 4     That was the original mass

v = 16

KE = 1/2 4 * 16^2

KE = 2 * 256

KE = 512

When the velocity is doubled the KE becomes 4 times as big.

4*128 = 512

Answer:

kingdom plantae

Explanation:

members of this kingdom have a cell wall that gives their cells a box like structure

Organisms that belong to Kingdom Monera, Protista, Fungi, and Plantae all have cell walls.

The cell wall is the outermost covering of the cell which provides the cell with a rigid structure and protects it from the outside environment. It is present outside the plasma membrane.

The composition of the cell wall differs in different organisms. The cell wall in plants is composed of cellulose, hemicellulose, and pectin. In algae, the cell wall is composed of glycoproteins and polysaccharides.

Bacteria that belong to Kingdom Monera possess a cell wall composed of peptidoglycan while the organisms of Kingdom Fungi have a cell wall made up of chitin.

Therefore, organisms of the four kingdoms Monera, Protista, Fungi, and Plantae all possess a cell wall.

Question:

I failed to find the options, but I will post the way by which you can construct Punnett squares.

Answer and Explanation:

First, you need to know both parental individuals´ genotypes. From these genotypes, you will get all the possible gametes for each parent, following the principle of simple segregation.

Then, by using a simple square, you will make the crosses. This is:

In the attached files, you will find an example of the cross between two pure-breeding plants.

Answer:

C. Not Likely to form any bonds

Explanation:

Assuming this atom is of neutral charge, it would be neon. We can tell as it has 10 electrons total. 2 in the first shell, 8 in the second. Noble gasses do not  form bonds, generally speaking.

Furthermore, any atom, ion or not, that has a full valance (outermost shell) is generally not likely to form bonds.

Answer:

1. Conduct a Hazard Analysis

2. Determine critical control Points

3. Establish the critical limits

4. Establish measures to control the hazards

5. Establish corrective actions

6. Establish verification procedures

7. Establish record-keeping and documentation procedures

Answer:

Gene flow is the exchange of alleles between two or more populations. For this reason it is sometimes referred to as allele flow or gene migration. While migrating animals often carry new alleles from one population to another, they must interbreed with the new population for gene flow to occur. In the image below, a beetle from a population of brown beetles migrates into a population of green beetles.

Answer:

Salinidad, acidez, oxígeno, niveles de luz y temperatura.

Explicación:

Los factores ecológicos como la salinidad, la acidez, el oxígeno, los niveles de luz, la profundidad y la temperatura son los factores que afectan en gran medida a los ecosistemas acuáticos porque estos factores proporcionan ambiente a los organismos que viven en el ecosistema. La salinidad y acidez tiene un efecto directo sobre las plantas acuáticas, si la salinidad y acidez es muy alta los organismos de ese ecosistema morirán. Los niveles de oxígeno y luz también tienen un gran impacto en los animales acuáticos, si se reducen los niveles de oxígeno y luz, los organismos morirán por asfixia y las plantas no pueden producir alimentos si los niveles de luz son bajos. La temperatura del agua ayuda a la supervivencia de los organismos porque muchos organismos son sensibles a la temperatura.
