Answers
Answer:
Chemicals make up the bodies of living organisms, all require H20, cells consist of 75% water. Organisms are made of matter (composed of chemical elements). ... An element that is essential for life but required in small amounts.
Explanation:
Chemicals make up the bodies of living organisms, all need [tex]H_2O[/tex], cells that are 75% water. Organisms are made of matter which is made of chemical elements.
What are Chemical Elements?A chemical element is defined as a chemical substance that cannot be broken down into other substances where the fundamental particle of a chemical element is an atom, and chemical elements are distinguished from each other by the number of protons in the nuclei of their atoms. goes.
Carbon, oxygen, hydrogen, gold, silver and iron are examples of chemical elements where each element has only one atomic form. Elements can combine with each other to form a wide variety of more complex substances called compounds where the number of possible compounds is almost infinite where there are probably a million known and more are being discovered every day.
Thus, Chemicals make up the bodies of living organisms, all need [tex]H_2O[/tex], cells that are 75% water. Organisms are made of matter which is made of chemical elements.

Answers
Answer:
olfactory bulb . . . hippocampus
Explanation:
Neurogenesis has been seen in the olfactory bulb and in the hippocampus. Thus, option B is correct.
What is Neurogenesis?During pre-natal development, new neural cells are formed in the brain by a process called neurogenesis.
The human brain is consist up billons of nerve cells are divided into neurons, glia, and an undetermined cell types.
In the early stage Neurogenesis, separation of neural plate from the ectoderm occur by a folding form called neural groove.
These neural groove fuse to form neural tube, a precursor to the central nervous system (CNS), and the neural crest.
The neural crest have stem cell property become differentiated into multiple leads to development of tissues and organs.
There are two regions in the brain known as the hippocampus and occipital lobe where neurogenesis are seen.

Answers
Machine operating is the non examples of environmental systems.
What is environmental systems ?The environmental system can be defined as an ecological sense as the set of interactions between the elements of the biosphere and it includes the atmosphere, the hydrosphere, the lithosphere, and the ecosphere.
The atmosphere is composed of nitrogen (78%), oxygen (21%), and other traces of carbon dioxide, argon, water vapor, Although the atmosphere is approximately 1,100 km high, the stratosphere and the troposphere are the main atmospheric interactors.
The hydrosphere consist of water in all form like solid, liquid, and gas and dissolved elements like sodium, magnesium, calcium, chloride, and sulfate.
The lithosphere which is a thin crust between the mantle and the atmosphere, it is around 100 km thick, it can be considered in interaction with the biosphere; Main components are oxygen, silicon, aluminum, iron, calcium, sodium , potassium and magnesium.

What is the cell theory?A biological hypothesis asserts one or both of the following: an organism is made up of autonomous cells, and its qualities are the sum of those of its cells; the cell is the primary structural and functional unit of living matter.
Theodor Schwann was the scientist who proposed the theory of cells in 1839.
Because it hasn't been verified yet and there are no known means to verify it, the label “cell theory” is acceptable. However, given how many facts support this idea, it is thought to be accurate. It also backs a number of other theories derived from Cell Theory.
Therefore, the correct option is a. Schwann and Hooke.

According to most theories about the evolution of early life on earth, the atmosphere had an abundance of ammonia, methane, and carbon dioxide, shown above. Free energy from lightning could have allowed chemical reactions to occur that generated the precursors to life on earth. Which inorganic molecule(s) are accurately paired with their role in the formation of organic molecules necessary to life?
A) Ammonia would have provided the nitrogen found in the amine groups of amino acid and the nitrogenous bases in DNA.
B) Methane would have provided the hydrogen to form water, a universal solvent for chemical reactions supporting life.
C) Ammonia would have provided the electrons to generate ATP using an electron transport chain within the mitochondria.
D) Carbon dioxide would have provided the oxygen needed to perform photosynthesis, resulting in the production of glucose.
Answers
Answer:
A
Explanation:
The correct option would be A.
The presence of ammonia in the atmosphere of primitive earth provided the nitrogen found in the amine groups of amino acid and the nitrogenous bases in DNA. This has been proven through the simulation experiment of the primitive earth's atmosphere by Stanley Miller and Harold Urey.
The water in the primitive atmosphere was formed from the condensation of water vapour from volcanoes that were characterics of the earth's environment while oxygen in itself is not needed for photosynthesis but a by-product of it.

For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living.
