Answer:
A
Explanation:
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.

How do protons (hydrogen ions) move through
ATP synthase?
Answer:
Protons flow down their concentration gradient into the matrix
Explanation:
The proton gradient produced by proton pumping during the electron transport chain is used to synthesize ATP. Protons flow down their concentration gradient into the matrix through the membrane protein ATP synthase, causing it to spin (like a water wheel) and catalyze conversion of ADP to ATP.

Hey, I need help with these questions please:
Answer:
D
Explanation:
Name two nutrients that plants need.
Answer:
Sunlight and water.
Explanation:
The sun is the plant's most important nutrient. Plants convert sunlight into sugars in order to grow. Water is needed in two ways, it serves as both a solvent for mineral salts that are carried inside plant cells, and it is an essential component of photosynthesis. The questioner might have asked "name one" so they don't have enough information to answer with any greater certainty - but the answer remains the same regardless of how many nutrients they ask about.
Minerals are also required by plants in order to function properly including calcium, potassium, iron, magnesium just to name a few minerals which are found in healthy nutritious produce!

sunlight and water

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.

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.
Precipitation moving from higher to lower elevations on the ground is called___?
Answer:
Evaporation
Explanation:
Evaporation is the process in which percipitation moves higher to lower elavations on the ground. Evaporation is when the sun heats up and dries out the water causing it to rise up to the clouds which then causes rain for another time. ( I am not completely sure)

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:

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.

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?
