Answer:
Solids
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.

Are humans a dead end host for streptococcus pneumonia? If yes please explain why. Thank you!
Answer:
No, because Pneumonia can be transferred from one person to another.
Explanation:
Because humans are the only natural host for S. pneumoniae, our data suggest that the CbpA-mediated recruitment of complement FH may contribute to host tropism of this pathogen. A person can spread the germs that cause pneumonia when he or she coughs and expels the bacterial or viral infections that caused the disease. The droplets containing the virus or bacteria can land on a common surface, such as a table, telephone, or computer. Anyone can get pneumococcal disease, it occurs more frequently in infants, young children, the elderly or in people with serious medical conditions such as chronic lung, heart or kidney disease. Others at risk include alcoholics, diabetics, people with weakened immune systems and those without a spleen.

Name three reasons, as to why, bacteria is so widespread into different life/ecosystems
Answer:
Bacteria are decomposers which break down dead material and recycle it. They also can be producers, making food from sunlight, such as photosynthetic bacteria, or chemicals, such as chemosynthetic bacteria.The most influential bacteria for life on Earth are found in the soil, sediments and seas. Well known functions of these are to provide nutrients like nitrogen and phosphorus to plants as well as producing growth hormones. By decomposing dead organic matter, they contribute to soil structure and the cycles of nature. Decomposers play a critical role in the flow of energy through an ecosystem. They break apart dead organisms into simpler inorganic materials, making nutrients available to primary producers.Explanation:
Why are braided streams common in sedimentary rocks before the arrival of plants on land ?
Answer:
Braided rivers have a multithreaded plan form comprising many confluences and diffluences (Miall, 1977). Braid bars and channels can be classified as a hierarchy depending upon their relative size, and three orders of braiding can be seen in proglacial rivers with constant discharge. First-order braid bars are those largest bars which are separated by major channels. First-order bars are made up of a series of smaller, second-order braid bars, which are separated by smaller channels. Third-order braid bars are contained within second-order bars. Complexity of braid pattern is, however, strongly stage dependent, with rivers losing their braided character during peak flood conditions. Braid bars, mid-channel bars, unit bars, and islands have been described in braided river systems on a range of scales ranging from meters to kilometers. All bars are subject to dissection , remobilization, and migration by the appropriate discharge magnitude and frequency (Miall, 1977, 1983).

In gymnastics, a gymnast must be able to balance on a balance beam. What is the best explanation for what forces are acting on the gymnast on a balance beam? (2 points)
The forces are balanced when the force of gravity pulling you down is the same as the force of the balance beam pushing you up.
The forces are unbalanced when the force of gravity pulling you down is the same as the force of your legs pushing you up.
The forces are balanced when the force of gravity pulling you down is stronger than the force of the balance beam pushing you up.
The forces are unbalanced when the force of gravity is reduced to the same force as the balance beam pushing you up.
Answer:1
Explanation:Because gravity always pulls you down even when your standing on an object.

All cells in the body have the same genome, with a couple of exceptions. What are these exceptions?
Answer:
red blood cells, which contain no DNA in their mature state, and some immune system cells that rearrange their DNA while producing antibodies
Cell is the basic unit of life and they contain the needed information known as the DNA (genetic material) to carry out the basic life functions and processes.
All cells in the body essentially have the same genome except some red blood cells and some immune cells.
Red blood cells do not contain as DNA as they lack a nucleus so they are an exception to the rule. While some immune cells needs to reassemble their genome in order to aid in the production of antibodies.
Actually, gene expression comes in with this because cells become different as a result of the fact that a cell can decide which gene is to be expressed or not in accordance to its function it is supposed to perform.

do you think carbon sinks can ever completely reverse global warming, why or why not?
Answer:
Explanation:
Framed in this way, the problem of climate change becomes not one of simply producing greenhouse gas, but how quickly we do so when compared with the Earth’s natural ability to soak it up again. And it makes that natural ability – the continuing capacity of forests and oceans to act as carbon sinks – as significant a factor in deciding the likely course of rising temperatures in the near future as intended controls on our greenhouse gas emissions. Yet many people are unaware of this side of the carbon balancing equation. And if they are, they take it for granted – they expect that forests and oceans and other carbon sinks will continue to act as our environmental get-out-of-jail-free card.
Or, more accurately, our go-to-jail-slightly-slower card. While sinks have managed to grab about half the carbon released as human pollution in recent centuries, the rest steadily accumulates in the atmosphere. The forests and oceans simply can’t suck it in fast enough. At the last count, atmospheric levels of carbon dioxide registered almost 412 parts per million (ppm) and rising. That’s a 47 per cent jump since the beginning of the industrial age, when the concentration was near 280 ppm, and an 11 per cent rise since just 2000, when it was near 370 ppm. Without our natural carbon sinks working to buffer the impact, that figure would probably be closer to 700ppm today.
It makes sense, then, that the future behavior of Earth’s massive carbon sinks – and specifically the question of whether they will continue to bail us out by taking in carbon dioxide – is a key topic of research for scientists. How will tropical forests respond to warmer temperatures? Will ocean currents continue to carry carbon to the depths? What happens to the pace of climate change if the carbon-catching capacity of these sinks weakens?

Suggest an explanation for the evolution of the pigeon-like ancestor into the flightless dodo.
Answer:
It's ancestors were pigeon-like birds which flew to the island millions of years ago. There were no predators on the island. Gradually, the birds became much heavier, lost their ability to fly and evolved into the dodo.
Explanation:
What do all living things have in common? All have cells with a nucleus. All have a genetic code. All are made of two or more cells. All can perform photosynthesis.
Living beings are organisms that can respire, respond, grow, reproduce, and are made of cells. All living things have a genetic code. Thus, option B is correct.
What is a genetic code?A genetic code is a sequence of proteins and nucleic acids that act as a hereditary molecule that transfers the traits and characteristics to the progeny.
The code can be in the form of DNA or RNA and provides information about the genotype of the organisms that were passed from their ancestors.
The genetic code is in the form of triplets and is a universal system that codes for the same proteins in all organisms. It consists of the nitrogenous bases that through translation make the amino acids.
Therefore, option B. all living organisms have a genetic code.

using example, explain the concept of homeostasis
Answer:
Homeostatis: maintenance of constant internal environment (optimum temperature or optimum optimum osmotic concentration) that permits all the biochemical reactions and physiological functions to proceed with maximum efficiency.
▪For example, when we exercise, there is heat production in the body and the body temperature rises which gets detected by the nerve sensors present in the body and the temperature control system in the brain is activated. It then activates sweat glands that helps in bringing the body temperature back to normal.
