Jonathan designed an experiment to plant lima bean seeds. His variable was to change what kind of light each plant received. He
used a different kind of light with each plant. He hypothesized that the plant grown under the plant light would have the greatest
amount of growth. Did the data support the hypothesis? Explain.

Answers

Answer:

Yes, it was.

Explanation:

The data did support the hypothesis because the data given was generalized on the change of light each plant received. The hypothesis was that the plant light would have the greatest amount of growth. The data was the different light types and the hypothesis was which one he inferred would work best.

Answer:

- The type of plants used in the study

- The number of plants in each experimental group

- A complete citation of the source

Explanation:

Many different types of mutations can occur within the body. An individual experiences a mutation that changes a base in
a mRNA strand, but during translation the mRNA strand still creates the same protein. Which type of mutation is
responsible for the change in the mRNA base?

A.silent

B.missense

C.nonsense

D.insertion

Answers

Answer:

A. Silent, The type of mutation responsible for changing a base in the mRNA strand, without changing the coding aminoacid or protein, is called a silent mutation.

Explanation:

In a silent mutation occurs the change of a nitrogenous base in one of the codons that encodes an aminoacid, without changing the aminoacid or altering the structure or function of the protein to be synthesized.

In this type of mutations the change of the base does not mean the change of the aminoacid, because some aminoacids can be coded with more than one codon. In the case of Leucine, the codons that encode it are CUU, CUC, CUG or CUA, so even if a base changes, the final protein will be the correct one.

For the other options:

Missense: the change of the base in the DNA chain implies the change of the codon in the mRNA and of the encoded aminoacid, in that way a structural and functional alteration of the synthesized protein occurs. Nonsense: the change in the nitrogenous base in the DNA leads to the coding of a termination codon, so that the protein is ultimately incomplete. Insertion: in this case there is the addition of more nitrogenous bases to the DNA chain, with respect to the original one.

Answer:

Lithosphere:

The lithosphere is the rigid outermost layer of the earth known as the mantle and the crust. And it is defined by its rigid mechanical properties.

Asthenosphere:

This layer is highly viscous and is very mechanically weak and is located below the Lithosphere it is also known as the ductile region of the upper mantle.

Mesosphere:

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature decreases as altitude increases.

The glaciers are visible because Ice floats when it freezes .This particularly helpful to life as it insulates the water below and is home to a variety of animals. Which is property of water is the reason that we can see icebergs float

Answers

Answer:

Water is denser as a liquid than as a solid.

Explanation:

The property of water that makes icebergs float on is due to the fact that water as a liquid is denser than as a solid.

According to the rules of floatation, a less dense substance will always float on a denser liquid because a body will always displace its own weight when placed in a liquid. At room temperature, water as a liquid has a density of 1 g/cm3 but if the same water forms ice, the density would be 0.92 g/cm3. Hence, when ice is placed on water, it will float on it.

Answers

Answer:

A. Cell membrane

Explanation:

The cell is the basic unit of the living organisms. The cell consists of the various cell organelles like nucleus, mitochondria and Golgi. The cell membrane covers the cell boundary.

The outer shell protects the egg and allows the exchange of moisture. The plasma membrane performs the similar functions ad allows the transport of some selected particles only.

Thus, the correct answer is option (A).

Answer:

A. cell membrane
