Answer:

Florida is close to the Atlantic Ocean, so it is prone to hurricanes.  Technologies that can help Florida include hurricane shutters for windows and satellites that detect air movement over the ocean.  Kansas is landlocked and is in the infamous Tornado Alley. The Warn-on-Forecast tool and safe rooms built in basements would be useful in this area.  California is close to the Pacific Ocean and regularly suffers from drought. Water conservation devices and desalinization plants would be helpful in this region.

Answer:

The correct answer is - If a parasite kills its host, it will then have to find a new host in order to survive.

Explanation:

Parasites are organisms that depend on other organisms for their food and energy in order to survive. The organism that they depend on is called their host. In this only parasites get benefitted while hosts are harmed.

Although parasites harm their hosts, parasites tend to not kill the host as its best for them so they do not have to find another host and again establish control on the host's body and body functions, for their survival.

Because top consumers have less energy than producers, there is only enough food for a few top level consumers, but there is plenty of food for herbivores lower down the food chain.

Forest ecology is the scientific study of forest patterns, processes, flora, fauna, and ecosystems. Forest management includes forestry, silviculture, and forest management.

The existence of all species in the forest in a well-balanced and environmentally friendly manner is the function of the forest ecosystem.

Forest ecosystems are classified as boreal, temperate, or tropical rainforest ecosystems.

The transfer of energy from one trophic level to the next, up the food chain, is shaped like a pyramid, with the base being wider and the top being narrower.

Because of this inefficiency, there is only enough food for a few top-tier consumers, but plenty for herbivores lower down the food chain.

Thus, top consumers were the least numerous.

When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.

The simplest instance of visible light reflection is a smooth pool of water's surface, where incident light is orderedly reflected to provide a clear image of the landscape around the pool.

When you throw a rock into a pool, it disturbs the water and causes waves, which prevent reflection by spreading the light rays in all directions.

The incoming light wave is referred to as an incident wave, and the wave that is bounced away from the surface is termed the reflected wave. Visible white light that is directed onto the surface of a mirror at an angle (incident) is reflected back into space by the mirror surface at another angle (reflected) that is equal to the incident angle, as presented for the action of a beam of light from a flashlight on a smooth.

Therefore, When waves of light (and other electromagnetic radiation) come into contact with a surface or other boundary that does not absorb the radiation's energy, the waves bounce off the surface and back into space.

Answer: Mitosis and meiosis are alike in that they both are a kind of cell division. They are different in that mitosis produces two cells identical to the original, while meiosis produces cells that only have half the chromosomes of the original. Meiosis ends up with haploid cells, while mitosis endup with diploid cells.

Answers: examples of host defence mechanism include: Innate anatomical and physiological barriers, Innate cellular and chemical defenses.

Explanation:

The capability of the human body to resist almost all types of organisms or toxins that tend to damage the tissues and organs is known as IMMUNITY. This host defence mechanism can be classified into INNATE or adaptive immunity.

The immunity that results from general processes, rather than from processes directed at specific disease organisms is called the INNATE IMMUNITY. The anatomical and physiological barriers of the innate immunity provides the first line of defence against pathogens. Examples of these barriers of the innate immunity includes:

--> Destruction of swallowed organisms by the low stomach pH and digestive enzymes

--> The vigorous mucociliary clearance mechanisms of the respiratory airways and lungs.

--> Resistance of the skin to invasion by organisms

While examples of innate cellular and chemical defenses include:

--> Phagocytosis of bacteria and other invaders by white blood cells and cells of the tissue macrophage System

--> lysozymes, a mucolytic polysaccharide that attacks bacteria and cause them to dissolute.

--> basic polypeptides which react and inactivate certain types of gram- positive bacteria

-->natural killer lymphocytes that can recognize and destroy foreign and tumor cells.

Answer:

Additional Information: Mutualism is the relationship where both organisms get positive results from it. An example of mutualism is the relationship between remora and shark.When one organism lives on another organism, that type of symbiotic relationship is called parasitism.

Answer:

Making stuff with mud is science because these are experiments used to establish facts and principles about mud and/or the different types of soil constituting the mud

Explanation:

Science is a discipline that studies the establishment of facts, principles and methods through experimentation and instills processes of investigations to learners. Making stuff with mud can be used to establish facts and principles e.g clay soil has smooth and fine particles and has high adhesive forces of attraction with water and hence will make longer and thinner ribbons while sand has large rough particles which make large and chubby (I couldn't think of another word) ribbons due to the weak adhesive forces between the particles and water.

Explanation:

Scientists name animals and plants using the system that describes the genus and species of the organism.

Answer:

C

Explanation:

The activator is a sequence-specific DNA-binding protein that is present in some tissues but not in other tissues. The correct option is C.

Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.

Because a particular protein can only be made when its gene is turned on, gene expression is significant.

However, there are several steps involved in translating a gene into a protein, and one of these steps—the creation of proteins—is crucial in the gene expression pathway that can be changed in cancer.

According to the diagram, the activator is a DNA-binding protein that only binds to certain sequences in select tissues.

Thus, the correct option is C.

Answer:

Carbon sources

Carbon sequestration

Explanation:

Carbon sources are regions that produces atmospheric carbon dioxide. This carbon dioxide is naturally added to the atmosphere when organisms respire, decompose, rocks with carbonate are weathered and volcanoes erupt.

Carbon sequestration is the process of taken and storing atmospheric carbon dioxide. The method helps in reducing the amount of carbon dioxide in the atmosphere which in turn reduces global climate change.

The half life of carbon -14 is 5730 years. The carbon -14 undergoes decays to form nitrogen -14. 1000 atoms of nitrogen is formed from 1000 atoms of carbon. Hence carbon -14 decayed from 2000 atoms to 1000. Therefore it is decayed by one half life and the age of the sample is about 5700 years or more accurately 5730 years.

Unstable radioactive  isotopes of atoms undergo spontaneous nuclear decay by the emission of charged particles such as alpha or beta. The time required to decay half of the initial amount of the isotope is called half life.

Carbon -14 undergo beta decay and the nuclear reaction is given as follows:

[tex]\rm _{6} ^{14}C \rightarrow _{7}^{14}N + _{-1}^{0}e[/tex]

Thus, one carbon atom is converted one nitrogen atom. Hence, 1000 nitrogen atoms are formed from 1000 carbon atoms. The remaining number of carbon atoms in the rock sample is 1000. Thus, the initial amount was 2000.

The half life of carbon -14 is about 5700 years. Hence, it takes 5700 years to decay from 2000 to 1000 atoms. Therefore, option B is correct.
