Hey there!

1.The metric system is a decimal system of measurement whose units are based on certain physical standards and are scaled on multiples of 10.Metric units of length are easy to use because they are based on multiples of 10.


2.You can immerse the solid in water and measure the volume of the water displaced. The solid cannot dissolve in water.


3.A degree on the Fahrenheit scale must be smaller because there are 180 degrees between freezing and boiling as compared to 100 degrees for the same range on the Celsius scale.


Hope this helped @ShaggySnaps

Which of the following statements is correct with respect to the use of oxidized sulfate by some bacterial groups
Gnesinka [82]

All of the above.

<h3>What are sulfur oxidizing bacteria?</h3>

Any of a wide range of microorganisms that can metabolize sulfur and its components and are significant in nature's sulfur cycle are known as sulfur bacteria. Hydrogen sulfide (H2S), sulfur, and thiosulfate are a few of the typical sulfur compounds that are used by these bacteria as a source of energy. Sulfate is the end result of the oxidation of sulfur.

In deep earth deposits, <em>Thiobacillus</em>, which is common in both marine and terrestrial settings, produces sulfuric acid, which dissolves metals in mines but also corrodes concrete and steel. It also oxidizes sulfur, generating sulfates that are helpful to plants.

I understand the question you are looking for is this:

In seawater, sulfate is the most common anion after chloride. Which of the following is correct with respect to the use of sulfate by some bacterial groups?

  1. Oxidized sulfur-containing molecules have redox potentials lower than those of the nitrogen series.
  2. Oxidized sulfur molecules such as sulfate and sulfite serve as electron acceptors.
  3. Sulfate and sulfite can receive electrons from hydrocarbons.
  4. Sulfate-reducing archaea and bacteria are widespread in the ocean.
  5. All of the above.

What two statements are true for fungi?
Tamiku [17]

Answer:

Fungi are, in fact, more closely related to animals than plants. They are heterotrophs and do not carry out the process of photosynthesis because they do not contain the green pigment chlorophyll. Unlike animals, fungi do not ingest their food. Fungi release digestive enzymes into their food and digest it externally.

A rocket accelerated at 65 m/s2 with the force of 54,080 N. what is the mass of the rocket?
madreJ [45]

The mass of the body is 832 Kg.

<h3>What is the mass?</h3>

The mass of a body could be obtained from the second law of motion as propounded by Newton. We know that; F = ma

F = force

m = mass

a = acceleration.

Given that the rate of change of momentum is directly proportional to the impressed force;

F = 54,080 N

a =  65 m/s2

m = F/a

m = 54,080 N/ 65 m/s2

m = 832 Kg
