Answer:

In a process called cellular respiration, chemical energy in food is converted into chemical energy that the cell can use, and stores it in molecules of ATP. ... When the cell needs energy to do work, ATP loses its 3rd phosphate group, releasing energy stored in the bond that the cell can use to do work.

A environmental scientist buys 20 gallons of oil eating bacteria to help remediate an area affected by an oil spill. The volume of water the scientist wants to cover with this bacteria is 5 ft³. What volume of water can the scientist cover with the bacteria she purchased? (1 gal = 0.13 ft³)

Answers

Answer:

2.6  [tex]ft^3[/tex]

Explanation:

Using the conversion factor:

1 gallon = 0.13 [tex]ft^3[/tex]

Therefore,

20 gallons = 20 x 0.13

       = 2.6‬  [tex]ft^3[/tex]

This means that only 2.6  [tex]ft^3[/tex] out of the 5  [tex]ft^3[/tex] total volume of water the scientist wants to cover can actually be covered by the bacteria that was purchased.

A. It is added back to the soil by decomposers.


B. It is used by the producer to pass on to the next trophic level.

C. It is used for cell processes or released as heat.

D. It is consumed and used by the consumer.

2. Why is there less biomass at the top of the energy pyramid?

Consumers are the organisms that depend on others for food and energy for the metabolic process while the producers produce their food at the trophic levels.

The correct options are 1. C, 2. A, 3. A, 4. A and 5. A.

The trophic levels can be explained as:

1. In the trophic levels the energy gets decreased as it passes from one level to another because it is used in the cellular process it is released in the form of heat.

2. Secondary and tertiary consumers have to feed a lot and hence, they are fewer in number compared to the producers. They maintain the population and balance out the producer and consumer ratio.

3. According to the 10 % rule of energy transfer, the Tuna will receive 135 Kcal of energy because the energy decrease by 10% as one moves from the lower trophic to the upper levels.

4. The species that are non-native to a place or region are called invasive species hence, the Kudzu plant is the invasive species as it is introduced from Japan.

5. Given,

Energy of Seal = 2,500 Kcal

The energy of polar bear = 375 Kcal

The 10% of 2500 will be 250 and the 5 % 125 thus, 15% is the efficiency.

Therefore, the correct options are 1. C, 2. A, 3. A, 4. A and 5. A.

Priscilla was building a circuit that used copper wires to connect a battery to a light bulb. As she connected the final wire from the light bulb back to the battery, the light bulb turned on. Priscilla knew that current was now flowing through her closed circuit. What makes the current in the circuit flow?

Answers

Answer:

The complete path provided by the closed circuit enables electric current produced by the battery to flow round the circuit

Explanation:

Electric current consists of charges (electrons) in motion from one region to another.

An electrical circuit is any closed path through which electric current can flow.

An electrical circuit consists of an energy source that supplies the electrons moving, a path along which the electrons can travel, and a load or appliance that uses the electrical energy. When the circuit is broken at any point, electrons will cease to flow since there is no complete path for it to flow. Such a circuit is known as an open circuit.

In the circuit built by Priscilla, the battery serves as a source of energy by providing the electrons that moves round the circuit. The wires provides the path for electrons to flow from the battery through the light bulb and back to the battery. When she connected the final wire from the bulb back to the battery, the circuit becomes complete/closed and current then flows to light up the bulb.

1. The more bases there are per codon the more information you can code for. There are only 22 different amino acids, in consequence we need minimum 3 bases per codon.

2. codon

three nucleotides—called a triplet or codon—codes for one particular amino acid in the protein. The nucleotide sequence in the DNA is first transcribed into a molecule of messenger RNA (ribonucleic acid).

3. Known as alpha helices and beta sheets, these stable folding patterns make up the secondary structure of a protein. Most proteins contain multiple helices and sheets, in addition to other less common patterns (Figure 2). The ensemble of formations and folds in a single linear chain of amino acids — sometimes called a polypeptide — constitutes the tertiary structure of a protein. Finally, the quaternary structure of a protein refers to those macromolecules with multiple polypeptide chains or subunits.

OKAY I THINK EVERYTHING IS RIGHT BUT SORRY IF WRONG ;)

The mRNA sequence could be translated into three different sets of amino acids because of the degeneracy of the genetic code.
Using the genetic code to translate the mRNA sequence, we get the following three possible sets of amino acids:Set 1: isoleucine-phenylalanine-leucine-serine-valine-arginineSet 2: isoleucine-asparagine-valine-leucine-serine-arginineSet 3: isoleucine-asparagine-leucine-serine-valine-arginine

What is a nucleotide sequence?

A nucleotide sequence is the order of nucleotides (the building blocks of nucleic acids) in a DNA or RNA molecule.

Nucleotides are composed of a sugar, a phosphate group, and a nitrogenous base, which can be adenine (A), cytosine (C), guanine (G), thymine (T) (in DNA) or uracil (U) (in RNA). The specific order of these nucleotides in a DNA or RNA molecule determines the genetic information that the molecule carries.

Answers

I think it’s D bye have a nice day

The actual volume of bromine in each beaker will be same only the difference in height will be comparable. Therefore, option (C) is correct.

What are the properties of liquid ?

A liquid's attributes are;

1) Compared to the volume occupied by a gas, the volume of a liquid is relatively stable at conditions that allow it to remain in the liquid state.

2) A liquid will take the form of the container it is placed in.

3) A liquid's surface in a container must be flat for the attraction forces between its molecules to be in equilibrium both at the liquid's surface and within its body.

Therefore, there will be variations in the measured height of the same volume of bromine in each beaker given that the volume of the bromine is measured in a 50 ml beaker and a 100 ml beaker.
