You overhear your mom and dad talking about having a well installed in your yard. What advice can you offer them about determining the placement and potential effectiveness of the well? Think about what you know about how wells factor into the groundwater systems running below the surface of the Earth.

Answers

Answer:

Built well where water table present nearer to surface.

Explanation:

My advice for them about determining the placement and potential effectiveness of the well is that the well should be installed where the groundwater present nearer to the surface, the reason behind this advice is that minimum work and energy will be used for digging well. If the water table is present very deep, more work and energy will be utilized on the digging of the well. Those areas where more rainfall occurs, the depth of water table is less as compared to arid zones because due to more rainfall more water goes inside the soil and the water table rises.

Answers

Explanation:

Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released. Fusion is the process that powers active stars, releasing large quantities of energy.

Explain how scientists use geologic time to determine the age of landforms. (3 points)

Answers

Answer:

I will!

Explanation:

to determine the related age of different rocks geologists start with the assumption that unless something has happened in the sequence of sedimentary rock layers the newer Rock layers will be on top of the older ones this is called the rule of superposition with absolute age dating you get a real age and actual years

Answer:

Geologic time uses the layers of rock to describe the relationships of events and their sequence in chronological order over the history of Earth. The layering is a result of the buildup of tiny bits of rock, sediment, or lava cooling at the surface over many years. Think of it like a stack of pancakes—the bottom layer is the one that was placed first and therefore is the oldest. The sediments that create the layers of Earth are stacked one on top of the other.

Identify the types of point mutations depicted.

Answers

Answer:

The types of point mutation depicted are:

1. C. Silent mutation

2. B. Nonsense mutation

Explanation:

Point mutation is known to be a mutation that actually affects a single nucleotide and it has to do with the substitution of one base for another. This substitution can occur by changing, inserting or deleting a DNA or RNA sequence. A nonsense mutation refers to a change in DNA which leads a protein to either terminate or end its translation so quickly than expected. This mutation is commonly seen in humans.

Silent mutation is known to be the mutation in DNA  whereby there are no effects which are observable in an organism's phenotype. This type of mutation are seen as a specific type of neutral mutation.

According to the diagram, cell growth and preparation occur in steps 2 and 4, corresponding to phases G₁ and G₂ of cell cycle.

Explanation:

G₁ phase consists of the beginning of the cell cycle, following the process of previous division, and occurs in a cell that prepares for a next division. In this phase growth depends on the proliferation of mRNA to increase protein synthesis.

G₂ phase —third phase of the cycle— is the continuation of the process of cell growth induced by protein synthesis. Changes occur at the level of cellular components, as preparation of the cell prior to division.

The 1st Law of Thermodynamics states that energy is neither created nor destroyed only transfer to forms. Why is a food chain an excellent example of this Thermodynamic law?

Answers

Answer:

Food chain is an excellent example of the first law of thermodynamics.

Explanation:

First law of thermodynamics states that energy of the universe is constant. It is always found in the universe in some form or the other. It cannot be destroyed or totally used up and we cannot also create energy out of anything in this world. Energy transforms from one form to another form.

Food chain is considered to be an excellent example of 1st law of thermodynamics. Every living organisms in the world posses energy. And all living organisms consumed each other or eat each other for their survival and consumes these energy to survive. So the energy possessed in one organisms or animal is transferred to the other organism that is higher in the food chain when they eats the lower organisms or animal in the food chain.

Thus energy transfers form one form to another.

True or False:
The immune system is designed to protect against pathogens such as microscopic organisms and foreign substances that arise from outside the body

Answers

Answer:

True.

Explanation:

Protecting against pathogens such as microscopic organisms and foreign substances that arise from outside the body is the role of the immune system.

Answer:

true

Explanation:

Inside your body there is an amazing protectio­n mechanism called the immune system. It is designed to defend you against millions of bacteria, microbes, viruses, toxins and parasites that would love to invade your body. To understand the power of the immune system, all that you have to do is look at what happens to anything once it dies. That sounds gross, but it does show you something very important about your immune system.

When something dies, its immune system (along with everything else) shuts down. In a matter of hours, the body is invaded by all sorts of bacteria, microbes, parasites... None of these things are able to get in when your immune system is working, but the moment your immune system stops the door is wide open. Once you die it only takes a few weeks for these organisms to completely dismantle your body and carry it away, until all that's left is a skeleton. Obviously your immune system is doing something amazing to keep all of that dismantling from happening when you are alive.

how can an understanding of the interactions between matter and energy help you understand whether different carbon reservoirs are growing or shrinking?

Answers

Answer:

Carbon reservoirs are shrinking.

Explanation:

the interactions between matter and energy help us to understand and provides information whether different carbon reservoirs are growing or shrinking because when the matter converts into energy, it releases heat energy along with different gases. For example, when volcanic eruption occurs the carbondioxide gas is released in this process which shows that carbon reservoirs are shrinking.

Answer:

By understanding the amount of energy devoted to processes that release carbon versus processes that store it, one can gain an understanding of how the carbon concentrations in different reservoirs are changing.

In a certain plant, the allele for red flower color (R) is dominant over the allele for white flower color (r). A cross is performed between a plant with red flowers and a plant with white flowers. The offspring are 47 plants with red flowers and 51 plants with white flowers. What are the genotypes of the parent plants?

Answers

Answer:

Rr and rr

Explanation:

The genotypes of the parents would be heterozygous red (Rr) and true-breeding white (rr).

Since the allele for the red flower color (R) is dominant over that of the white flower color (r), for a cross to produce both red and white flower color plants, the red parent must be heterozygous (Rr) and the white parent true-breeding (rr).

       Rr    x    rr

   Rr    Rr    rr    rr

Rr = red

rr = white

If the red parents is true-breeding

        RR    x    rr

      Rr    Rr   Rr    Rr

All their offspring would be red without any white flower color.

Hence, the genotypes of the parent are Rr and rr.
