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

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.

What term describes parts of the body that are made from different kinds of cell

Answers

Answer:

The term that describes the parts of the body with different kindsof cells is organs, which in turn are made up of different tissues.

Explanation:

The cell is the structural and functional unit of all living beings, with the capacity to multiply and unite to form tissues.

Each tissue is a differentiated or specialized structure, formed by groups of cells of the same type, such as muscle, nerve, connective, cartilage and bone tissue, among others.

The specialized tissues in turn form organs, with specific structures and functions, such as muscle, brain and nerves or bones and joints. For this reason, organs are different body parts, formed by different kinds of cells.

C. All of the living and nonliving things that interact in and around a lake
D. All of the trout that live in a lake​

Answers

Answer:

B. All of the fish, bacteria, and mammals that live in a lake

Explanation:

In terms of biology an individual make population, population makes a species and interaction between different species makes community. Interaction of living and non-living things make an ecosystem.

Community involves interaction between all the living organisms present in a given environment. Hence, interaction between fish, bacteria, and mammals that live in a lake is a community.

Hence, the correct answer is "B. All of the fish, bacteria, and mammals that live in a lake".

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.

Answers

Answer: Adaptive radiation refers to the ability of living organisms to evolve rapidly from an ancestral forms into variety of other forms especially when the organisms move into a new environment that has abundant resources. The resources, which are present abundantly in the environment allow the living organisms to spread out in the environment and to find different habitats in the environments that favour their survival.In the question given above, adaptive radiation allows plants to fill different habitats (niches) that are found on land and to spread out rapidly.

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.

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.
