Answer:
Core samples are the samples of rocks that are obtained from the sub-surface by drilling. It is an expensive method to acquire these rocks. But these core samples are very useful for a geologist. They give the following pieces of information-
(1) It is used to study the subsurface lithology.
(2) The age to which these rocks belongs can be known.
(3) Porosity as well as the permeability of the rocks can be measured.
(4) They are used to determine the probable amount of productivity in oil in that rock.
(5) The core samples are also collected from different nearby places within a particular region in order to determine the extent to which the probable oil, petroleum, natural gas, and other valuable minerals are present.

During a home visit, a nurse discovers that a child in the household has a disability and has been experiencing seizures. in addition, the child's parent is indifferent to the child's physical, emotional, or medical needs and seems to provoke seizure episodes by harsh verbal exchanges with the child. the nurse believes that an intervention by an appropriate community resource is indicated. where should the nurse direct the referral?
Answer:
Child Protective Services (CPS)
Explanation:
In the United States, if there are suspicions of abuse occurring towards a minor in a household, the CPS should be contacted. In some states, CPS is known as the Department of Children & Family Services.
If the nurse finds that the child's parent behavior towards the disabled child is causing distress and can be classified as neglect and abuse, she should contact the CPS. The CPS would conduct an investigation and remove the child from the custody of the parents until the results of the investigation have clarified the ongoing situation.

Researchers at the University of Georgia have evaluated trends in streamside forests in areas within roughly 400 feet of the state’s streams and rivers. A decline in streamed forests is evident across much of the state. Between 1974 and 2005, 41 of the state’s 52 large watersheds showed declines in riparian forests. The greatest losses were in the Upper Chattahoochee, Middle Savannah, Upper Ocmulgee, and Middle Chattahoochee.
Stream-side or riparian land lies directly along rivers, streams, and other bodies of water and provide benefit to aquatic ecosystems. Most specifically, stream-side forests affect the trout populations in North Georgia. How?
A) Trees and shrubs provide both food and shelter for the trout. Tree roots provide a bedding place, while the plant life in general, is a source of nutrition.
B) Riparian vegetation helps to reduce the impact of invasive species which may compete with local fish, especially trout, for the resources needed for survival.
C) Trees and shrubs provide shade, which keeps the water temperature cooler. Lower temperatures allow the water to hold more oxygen, which in turn creates a healthier habitat for the trout.
D) Riparian vegetation traps and removes pollutants from the water. Trout are particularly susceptible to water pollutants. There is a direct correlation between pollutants and trout death.

In the system shown below, there are 80 x particles, all in region A (the left half of the box). No extra particles can enter the system. When the system is in equilibrium, what will be true of the particles?
A. Since there are no y particles, the system is already in equilibrium with all 80 x particles in a.
B. Due to the constant motion of particles, this system will never reach equilibrium.
C. In equilibrium, there will be exactly 40 x particles in A and 40 x particles in B, and those numbers will remain constant.
D. In equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and those numbers will fluctuate but will remain near 40.
Answer:
D. In equilibrium, there will be approximately 40 x particles in A and 40 x particles in B, and those numbers will fluctuate but will remain near 40.
Explanation:
The perfect euilibrium is hard to achieve given the fact that particles move and are in constant change, but the equilibrium is reached when both boxes have a close number of particles in each of them, for example 41 and 39, 40 and 40, 42 and 38, this change in the number of particles is due to the movement of the particles, but it is still reachable.

The Earth's lithosphere is broken up into a bunch of discrete pieces, called ________ that move around the surface of the planet.
a.plates
b.faults
c.rifts
d.boundries
Correct answer: A). Plates
The tectonic plates are the pieces of earth's crust and mantle, which is together referred to as the lithosphere. The lithosphere is a rigid outermost layer of the planet that is broken down into the tectonic plates.
The plates move because the earth's lithosphere has a higher strength than the asthenosphere. During an earthquake, the plates move over each other.
Hence, the correct answer would be option A.
The Earth's lithosphere is broken up into a bunch of discrete pieces, called plates that move around the surface of the planet. Therefore, option (A) is correct.
Tectonic plates form Earth's lithosphere. The semi-fluid asthenosphere supports these plates. At a few centimetres every year, they move constantly. Earth's mantle heat-driven convection currents cause this movement.
Geological phenomena occur at tectonic plate borders. Plates diverge, forming new crust and volcanoes. When plates contact, they produce convergent boundaries, causing subduction or mountain uplift. At transform boundaries, plates slide past each other, triggering earthquakes.
Plate tectonics formed continents, oceans, mountain ranges, and geological features on Earth. Plate tectonics is essential for analyzing earthquakes, volcanoes, and Earth's long-term geology. Therefore, option (A) is correct.

Genetic variation is based on the: A. Sugars B. Hydrogen Bonds C. Phosphate groups D. Nitrogen Bases
Genetic variation is based on nitrogenous bases. Thus, the correct option for this question is D.
What do you mean by Genetic variations?Genetic variations may be defined as the difference in DNA sequences in the genomes between individuals within a population. The process of variation is initiated by the germ cells which is later shown by the somatic cell as well.
The genetic information is encoded in the DNA sequences with the help of nitrogenous bases like Adenine, Thymine, Guanine, and Cytosine. In these nitrogenous bases, the phosphate groups are attached in order to make them more functional. When the information is transcripted into mRNA, Uracil is encoded in place of thymine.
Therefore, genetic variation is based on nitrogenous bases. Thus, the correct option for this question is D.

A) The organism receiving the gene will modify it so it can work.
B) The gene carries the necessary enzymes to allow it to be read in corn.
C) The genetic code is read in the same way by all organisms.
D) The bacterium is similar enough to the corn that the gene is able to function.
Answer: C). The genetic code read by the organism in the same way by all organisms.
Explanation:
The gene is the smallest functional unit of the genome of the organism which is expressed in the organism and it produces a particular trait in the organism.
The genetic engineering is a field which facilitates the manipulation of the genetic makeup of the organisms.
The function of gene will remain the same even though it is transfered from one organism to other. Every gene exhibit a genetic code which helps in expression of gene in an oderly way. Thus irrespective of the organism the order of expression of gene will be maintained by genetic code.

Explanation:
how does sugar affect the surface tension of water?
Answer:
by reducing the surface tension of the water
Explanation:
The physical force generated by the atoms present in the liquid molecules as a result of the pull exerted on each other and the surrouding atoms compare to the water-air interphase is called the surface tension. This attraction is due to presence of hydrogen bonding between the water molecules.
Therefore the hydrogen bonding is the force at the thin-surface of water surfaces that sustain the water skater and a thin razor when placed.
When sugar is added to water ,the solute concentration of the water increases. The hydration energy is generated from the chemical reactions between sugar and water molecules. The hydration energy lowers the H-bonding(reduces the surface tension). Hence sugar lowers the surface tension
