Answer and Explanation:

An acid has a pH that is less than 7.  A base has a pH that is greater than 7.  Something that has a pH of 7 is neutral, but since it doesn't seem that the question is asking about neutral, you can ignore that for this problem.

Situation 1:   Base

Situation 2:  Acid

Situation 3:  Acid

Situation 4:  Base

Situation 5:  Acid

Situation 6:  Base

A.  Water directly out of the tap has a pH of 7.2.  When you add carbon dioxide (blow into the water), you get a pH of 5.1.  This means that the addition of carbon dioxide makes water more acidic.

B.  The most basic solution will have the highest pH.  This means that it will be water with bleach added to it.

C.  The most acidic solution will have the lowest pH.  This means that it will be water with instant coffee.

Darwin’s influence on modern scientific inquiry is largely (i)_______ ; yet while Darwin’s ideas inform fields as disparate as g
Phoenix [80]

Answer:

The answer is C) un-contested, appropriating

Explanation:

Although Darwinian ideas are purely biological and scientific, they have aided theoretical research in other sciences as well, psychology, in particular. The theory of evolution does not only explain the evolution of the human body, but also that of the brain. The brain's psychological mechanisms and the behaviors they produce can largely be understood through Darwin's theories; the theories of natural and sexual selection have directed much of psychological research.

In general, scientists accept Darwin's theories but in specific fields, such as social psychology and neuroscience, scientists have formulated surprising explanations using Darwinian ideas.

Where is ATP made in the chloroplast? What other activated carrier is produced in the space?
miskamm [114]

Answer:

The correct answer will be -

1. ATP production- Thylakoid membrane

2. Activated carrier- NADPH.

Explanation:

The photosynthesis reactions take place in the chloroplast which is divided into three membranes: outer, inner and thylakoid membrane. The light-dependent reactions take place in the thylakoid membrane which helps in the production of ATP molecules along with the activated carrier molecule called NADPH.  

The ATP molecule is synthesized by the ATP synthase enzyme located in the thylakoid membrane where electron transport chain produces a gradient of protons. These protons help in the production of ATP synthesis explained through the chemi-osmotic model.

Thus, the Thylakoid membrane and the NADPH are the correct answer.

Based on the information in the table, which of the following changes is least likely to produce a phenotypic
yaroslaw [1]

GAU to GAC​ is least likely to change phenotype of an organism.

<h3><u>Explanation</u>:</h3>

Phenotype of an organism is defined as the physical characteristics of an organism. This phenotype is dependent on the genotype of the organisms. This means the phenotypic characters are actually the expressions of the genes of the organisms. Now the genes are expressed in form of codons that are the three nitrogen base sequences. Each codon codes for a particular amino acid which in turn polymerises to from the protein which actually forms the phenotype of the organism.

Now there are 20 amino acids and 64 codons. Thus there are more than 1 codons for a single amino acid. So, if a codon is replaced by another codon which codes for same amino acid, then the phenotype is least likely to be affected.

Both the GAU and  GAC​ codes for aspartic acid. So the phenotype won't be affected much by this mutation
