The nitrogen cycle is an example of a(n) (blank) cycle. The options are biogeochemical, decomposer, energy, water, denitrification, nitrogen fixation, nitrogen limitation, or photosynthesis.
Answers
Answer: Biogeochemical, Nitrogen Fixation, and Denitrification
Explanation: A biogeochemical cycle is the cycling of a nutrient through the biosphere and the geosphere. Nitrogen fixation happens when Nitrogen Fixating bacteria take in atmospheric nitrogen and release Ammonia as a biproduct. Denitrifying bacteria then take in the ammonia and break it down into nitrite, nitrate, and finally back into atmospheric nitrogen. The cycle then repeats.
The nitrogen cycle is an example of a biogeochemical cycle. The correct option is A.
What is biogeochemical cycle?The transport and transformation of chemicals in ecosystems is referred to as a biochemical cycle. Wetland hydrologic conditions have a strong influence on these.
These processes cause changes in the chemical forms of materials as well as material movement within wetlands.
These cycles transport the elements required for life to survive throughout the ecosystem.
They are essential because they recycle and store elements, as well as regulate vital elements through physical facets.
A biogeochemical cycle describes how an element or compound, such as water, moves between its various living and nonliving forms and locations in the biosphere.
Water, carbon, nitrogen, phosphorus, and sulfur cycles are all important biogeochemical cycles for living organisms.
Thus, the correct option is A.

Can be specialized for specific tasks in multicellular organisms Contain DNA Contain nuclei Are surrounded by a cell membrane Were the first photosynthetic organisms on Earth Can be specialized for specific tasks in multicellular organisms
Answers
Answer:
See the answer below
Explanation:
Prokaryotic cell: contain DNA, are surrounded by a cell membrane, were the first photosynthetic organisms on earth.
Eukaryotic cells: can be specialized for specific tasks in multicellular organisms, contain DNA, contain Nuclei, are surrounded by a cell membrane.
Prokaryotic cells are the earliest cells to be formed in the pre-oxygen earth. The photosynthetic prokaryotic cells released oxygen into the atmosphere during the process of photosynthesis and as such, other forms of cells were able to evolve. Prokaryotic cells lack a nucleus and membrane-bound organelles. Their DNA lies freely within the cytoplasm but the cell itself is surrounded by a cell membrane that controls the movement of substances in and out of the cell.
The eukaryotic cells evolved much later after the prokaryotic cell. It has both nucleus and membrane-bound organelles. The DNA is located in the nucleus and the cell is also surrounded by the cell membrane. The eukaryotic cells can aggregate together to form tissues, organs, or systems for a specific task in multicellular organisms.
Answer:
Prokaryotes.
1. Have dna.

What is parasitic mode of nutrition? Explain with examples.
Answers
Answer:
Explanation:
ANSWER 1) Parasitic nutrition is a mode of heterotrophic nutrition where a parasitic organism lives on the body surface or inside the body of another type of organism (a host)
Examples of parasitic mode of nutrition are mosquito, ticks, lice, bedbugs , tapeworm
because lives on the body surface or inside the body of other organism called host.
ANSWER 2 ) Organisms that live in or on other organisms and acquire food at the expense of its host are called parasites. Most parasites are harmful to the hosts’ health; sometimes, they even kill the host. Both animals and plants may serve as a host. Unlike commensalism, the parasite causes some harm to its host. A few examples of parasites are louse on a human head, Cuscuta plant and tapeworms.
Cymothoa exigua is an unusual parasite. It is also known as the tongue-eating louse and is aptly named so as it is found in the mouth of the marine fish Lithognathus. It essentially severs the fish’s tongue, cutting off the blood supply and causing the tongue to fall off. The louse then attaches itself to the remains of the tongue and essentially acts as the fish’s new tongue.

What is a rule for making a neutral atom which has no charge?
Answers
The rule for making a neutral atom that has no charge is - Electron (E) = Proton (Protons).
Neutral atoms are atoms that have no charge or zero charges. It is known that an atom has three sub-atomic particles; Proton, Neutron, and electrons. Protons have a positive charge, neutrons have zero or no charges and electrons have negative charges.
There are three conditions possible:
The neutral atom that has no charge - The number of electrons and protons must be the same.E = P
A positive ion that has a positive charge - The number of protons has to be more than the number of electrons.E < P
A negative ion that has a negative charge - The number of electrons has to be more than the number of protons.E > P
Thus, the correct answer is - Electron (E) = Proton (Protons).

Ribosomes - Makes proteins
Cilia - Structures shaped like small oars that beat in unison to move the cell or the liquid around it
Nucleus - Protects DNA and is considered the “brain” of the cell
Golgi Apparatus - Modifies and packages proteins
Explanation:
The cell membrane separates the inside of the cell from the external environment, and regulates substances that enter and leave the cell.
The nucleus contains the genetic material of the cell, and therefore controls all cellular activities. It is also the site of transcription of mRNAs. mRNAs are translated at ribosomes.
The ribosomes are like factories that synthesize proteins through the process of translation.
When proteins have been produced, they are modified, packaged, and transported to their specific sites by the Golgi apparatus.
Mitochondria are energy-producing organelles - the site of cellular respiration.
Lysosomes are membrane-bound sacsin which waste products are digested
Some cells have cilia, which are hair like-structures that beat in unison to aid in locomotion. Another locomotory organelle is the flagella, which is a whip-like structure that helps some single-celled organelles to move.

The diagram shows molecules that a mitochondrion and produces during a cellular process. Which other molecules is a product of this process?
A. DNA
B. RNA
C. C6H1206 (glucose)
D. ATP
Answers
Answer:D
Explanation: DNA and RNA are held in the nucleus and have nothing to do with what is shown in the image which is the process of cellular respiration. What is fascinating is that the mitochondrion has its own DNA but it does not produce it in a cellular process. C is false because the mitochondrion takes in glucose so it will go alongside the pyruvate O2. So we can conclude that it produces ATP with H2O and CO2 during this process.
ATP molecule is also a product of the cellular process that occurs in the mitochondria.
MITOCHONDRIA:
The mitochondrion is a membrane bound organelle found in eukaryotic cells. The mitochondrion is regarded as the power house of a cell because it is the site of the cellular process that synthesizes energy for the cell.The cellular process that occurs in the mitochondria is called cellular respiration. Generally, cellular respiration breaks down glucose molecule in the presence of oxygen. The chemical equation is as follows:C6H12O6 (glucose) + 6O2 (oxygen) → 6CO2 (carbon dioxide) + 6H2O (water) + ATP (energy)
From the attached image, it can be seen that water (H20) and carbon dioxide (CO2) are products. However, ATP molecules is also synthesized during this cellular process.
