Answer:

Archaebacteria

Explanation:

Archaebacteria is a group of single-celled organism present on the earth which are thought to be descended from the ancient bacteria.

These bacteria can survive the extreme or harsh conditions present on the Earth-like in the hot springs.

The archaebacteria cell membrane is made up of ether-linked phospholipids which are ester-linked in Eubacteria and eukaryotes.  The sugar present in the archaebacteria is very similar to peptidoglycan in composition but it is not peptidoglycan.

Thus, Archaebacteria is the correct answer.

Question in link below.
bezimeni [28]

The correct answer is - They supply the energy needed for living processes.

Both the carbon and the nitrogen, are gases that are crucial for the survival of the organisms on the planet. They are mostly used by the producers in the ecosystems, as they need them to manage to perform their cycles, get nutrition, and of course energy. The producers are the basis of the ecosystems, so if they do not have a healthy supply of carbon and nitrogen, the ecosystems on the whole planet will collapse. The carbon and the nitrogen later go from one organism to another as the energy is transferred, and usually end up back into the atmosphere again.

Check Your Understanding 1. A system consists of components of matter and energy and the processes that involve the matter and e
irina [24]

Here, matter is gas, rock, lava and water, energy is heat, light. While the process in a system is melting and motion.

<h3>What is matter?</h3>

Matter is any material that has a mass and occupies space by having volume in classical physics and general chemistry.

Energy is a physical system's ability to perform work. The uppercase letter E is a common symbol for energy.

The act of determining the best intercommunication of processing units, as well as the best type and design of units in a process system.

In the given scenario,

  • Mater: gas, rock, lava and water.
  • Energy: heat, and light.
  • Process of system: melting and motion.

Thus, this way the given scenario can be classified.

Write a paragraph about why stem cells are a bad thing.PLZ NO PLADURISM
sdas [7]
Stem cells are very controversial for several reasons. Mainly, because stem cells need to be harvested from Embryos, which raises a huge ethical debate as to weather the (scientifically speaking, alive) embryo harvesting is not cruel and twisted, as these are human beings that are being used. Another ethical issue is that it is related to human cloning, and often times stem cells are mislabeled. Not to mention that there is an argument for the idea of cloning humans to be used for limb replacement, throwing everybody in a tizzy. Overall, one of the greatest medical acheivements of recent years has lots of issues that haunt it.

During aerobic respiration, the energy within the bonds of a glucose molecule is released in small amounts in a step-by-step, en
Rus_ich [418]

Answer: In this process, the energy released in form of ATP (Adenosine triphosphate) is used to POWER BIOCHEMICAL PROCESSES.

Explanation:

Aerobic respiration is the process by which living organisms breaks down glucose molecule to release energy. Oxygen is used for this process that's why the name aerobic.

Aerobic respiration releases energy within the bonds of glucose step by step in an enzyme controlled reaction. The stages of these processes includes:

--> Glycolysis: In this stage, glucose molecules are split to produce two molecules of ATP and two molecules of NADH (another energy carrying molecule).

--> Krebs Cycle: this is the second stage which occurs in the mitochondria of cells. The 2 ATP molecules generated from glycolysis is used to produce two more ATP, 8 more NADH and 2 molecules of FADH. This makes it a total of 16 energy molecules ( including 2 molecules of ATP from glycolysis).

--> Electron transport chain: this is the last stage of aerobic respiration which takes part at the inner member of the mitochondria. Electrons are transported from molecule to molecule down an electron-transport chain. Some of the energy from the electrons ( NADH and FADH from kreb cycle) is used to pump hydrogen ions across the membrane, creating an electrochemical gradient that drives the synthesis of many more molecules of ATP. As a result 32 more ATP are generated.

In conclusion, a total of up to 36 molecules of ATP from just one molecule of glucose in the process of aerobic respiration which are used to power biological processes.

Differential survival and reproduction is best described by which term? natural selection creationism inheritance of acquired ch
Sophie [7]
I believe it is natural selection. Natural selection is when over a period of time, traits that are formed to help the organism survive, are passed to the next generation. For example, if there were two types of rabbits. One had black fur and the other was white. They both lived in the artic. The black furred rabbits are mostly eaten by predators because their black fur is easily seen against the ice and snow. Over a period of time, the black furred rabbit would die out. The next generation would mostly have white fur to help them survive.
