I think the answer might be number 2

In the second class lever, the load is between the effort force and the fulcrum. The correct option is 3.

The term can refer to the juncture or assistance on which a lever rotates, as well as the focal point of a critical activity or situation.

The term "fulcrum point" in zoology refers to an anatomical structure that serves as point of support.

The load in second-class levers lies among both the effort and the fulcrum. A wheelbarrow is a prominent example, where the effort moves a great distances to lift a substantial load, with the axle and wheel acting as the fulcrum.

In a second-class lever, the effort is distributed over a large area in order to raise the load a short distance.

Thus, the correct option is 3.

Explanation:

Answer

A, because If you just match the base pairs in the question to A they would match up

The DNA sequences will produce the following m-RNA: AGC-UAC-ACU is TCG-ATG-TGA.  The correct option is A.

Finding the nucleic acid sequence, or the order of nucleotides in DNA, is the process of DNA sequencing. The four bases—adenine, guanine, cytosine, and thymine—are arranged in this way using any technique or technology.

Adaptor molecules that can recognize and bind to the codon, as well as the amino acid at a different place on their surface, are necessary for the translation of mRNA into protein.

These adaptors are made up of a collection of tiny RNA molecules called transfer RNAs (tRNAs), each of which is made up of roughly 80 nucleotides.

Therefore, the correct option is A. TCG-ATG-TGA is the sequence of m-RNA: AGC-UAC-ACU.

There are different types of natural selection. When one of the extremes phenotypes is being favored, directional selection is going on. Meanwhile, balancing selection increases the proportion of intermediate phenotype.

-----------------------------

Since I do not have the graphs, I will set different potential scenarios

Scenario 1: More light brown individuals than brown and dark brown

Probably after the dark-colored seaweed covered the rocks, snails needed to camouflage to avoid predation. So they must have suffered a change in color from light brown to dark brown.

Since this new trait is beneficial, natural selection favored it.

So animals change from being light brown to dark brown.

The type of natural selection acting here is directional selection.

A population that is under the effects of directional selection, experiences an increase in the proportion of individuals expressing an extreme phenotype, different from the original one.

In these cases, interactions between living organisms and the environment modify in the same direction.

So, the most abundant individuals turned from being light brown to being dark brown.

After dark-colored seaweed covered the rocks, the number of dark brown individuals increased, and the light brown individuals decreased.

                                            **********************

Scenario 2: More brown individuals than light brown and dark brown

This is the same situation as before. In this case, there were more brown individuals than snails expressing extreme phenotypes.

                                            **********************

Scenario 3:

Let us suppose that the original number of individuals was higher for one of the extreme traits, either yellow or grey.

After the seaweed-covered rocks, snails needed to camouflage to avoid predation, so they changed their color from yellow or grey to brown.

In this scenario, the intermediate phenotype is being favored by natural selection over the extreme phenotypes.

Balancing selection -or Stabilizing selection-, decreases the number of individuals expressing the extreme phenotype and favors individuals that exhibit medium-range characteristics. These are the ones that get to survive. Selective pressure is against h0m0zyg0tes.

In this case, the number of individuals expressing yellow or grey shells decreases, while individuals with brown color increase.

In the attached files you will find graphs for the three scenarios.

Answer:

volt

Explanation:

The potential difference is expressed in volt (V). The potential difference between two points is said to be 1 volt if the work is done in moving 1-coulomb charge from one point to other is 1 joule. 1 volt= 1 joule/ 1 coulomb Unit for measuring the potential difference is volt and instrument used for measuring potential difference is a voltmeter.

Answer:

Its potential is taken as zero potential. Thus the positively charged conductor has more positive potential than the earth. A  negatively charged conductor has negative potential less than that of the earth. The electric potential difference between two points in an electric circuit is the work done in moving a unit positive charge from one point to the other.

Experiment tools and methods were not as precise as they are now. Since tech has evolved so has the ways to look at atoms meaning that they will see new and different things.

This atomic model has changed over time. Scientists used the model to make predictions. Sometimes the results of their experiments were a surprise and they did not fit with the existing model. Scientists changed the model so that it could explain the new evidence. And  Because more experiments gave more data, theories and models for atoms changed to be more accurate over time.

Explanation:

Whilst the process of power generation itself does not produce environmental pollutants like fossil fuels which features the emission of carbon monoxide when they are partially combusted, it does leave behind radioactive wastes, in the same way, combusted charcoal or wood leaves ash behind.

The challenge with radioactive wastes is that they are inimical to human health and can remain so for hundreds of centuries.

Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.

Hydrosphere:-

The hydrosphere is the collective mass of water which is found on under, or above the surface of earth. Although earth hydrosphere is 4 billions old. A planet's hydrosphere can be liquid, vapor or ice.

Biosphere:-

The region or area of surface where living organisms survive their life are called as biosphere. The biosphere is a narrow zone on the surface of the earth where soil, water, and air combine to survive life.

Evaporation:-

The process in which water or liquid converts into vapor is called as evaporation.  In the case of water it starts vaporization at 100 degree C.

So, we can say that the conversion of matter from hydrosphere to biosphere is successfully achieved by evaporation.

Therefore, Water mover form hydrosphere i.e river to biosphere i.e atmosphere by a process of  evaporation.Thus, we can say that matter is move from hydrosphere to biosphere.
