61. A measure of acidity or alkalinity of water soluble substances. A pH value is a number from 1 to 14, with 7 as the middle point. Values below 7 indicate acidity which increases as the number decreases, 1 being the most acidic.
62. The pH scale typically ranges from 1 to 14, with lower numbers representing acids, higher numbers, bases. Neutral liquids like water have a pH of 7.
63. The pH scale ranges from 0 to 14.
64. A major problem with the use of fertilizers occurs when they’re washed off the land by rainwater into rivers and lakes.

Quiz Read the verse.
aleksley [76]

Answer:

B).  It will leave the next day.

Explanation:

The poem 'Raven' penned by Edgar Allan Poe explores the theme of regret, mental uncertainty, death, and lost love. In the given excerpt, the speaker asserts that 'On the morrow, he will leave me' for the Raven and becomes completely despaired. He becomes completely dejected thinking that 'tomorrow Raven will also leave(die)' like the 'other friends of him along with his hopes have flown(died) before.'

The speaker longed to see his love 'Lenore' in heaven again but this 'nevermore' from the bird makes him accept that the Raven(sense of loss and grief) will stay with him forever. Thus, <u>option B</u> is the correct answer.

Answer:

c. Isolate bacterial plasmid

a. Select the gene of interest + insert into plasmid

f. Plasmid taken up by bacterium

d. Bacteria replicate

e. Cloned gene harvested from bacteria

b. Protein product harvested from bacteria

Explanation:

Genetic modification refers to the biological procedure involving the manipulation of an organism's genome in order to achieve a desirable result. This process is carried out by inserting or deleting a desirable gene (encodes the desirable trait) from the organism.

Bacteria DNA called PLASMID is commonly used for genetic engineering/modification procedure. The plasmid is used to convey/carry the gene into the organism. According to this question, the correct order of the procedure is as follows:

- c. Isolate bacterial plasmid

- a. Select the gene of interest + insert into plasmid

- f. Plasmid taken up by bacterium

- d. Bacteria replicate

- e. Cloned gene harvested from bacteria

- b. Protein product harvested from bacteria

Explain how chemiosmosis functions in the cell. Discuss the energy transfers and explain the role of ATP in this process.
Lyrx [107]

The energy for ATP synthesis comes from organic molecules (such as carbohydrates), or from sunlight, or from inorganic electron donors. We can classify organisms according to their source of energy and organic carbon:

<span><span>heterotrophs – get energy and organic carbon from metabolism of pre-existing organic compounds (food)</span><span>photoautotrophs – use energy from sunlight to make ATP and their own organic carbon compounds from carbon dioxide chemoautotrophs</span><span> – use energy from inorganic chemicals to make ATP and their own organic carbon compounds from carbon dioxide</span></span>

Metabolic pathways carry out reactions that capture energy from these various sources (organic compounds, sunlight or chemicals) and couple them to synthesis of ATP from ADP.
