one day, prokaryotic bacteria got tired of bring referred to as a simple organisms by eukaryotic cells. they felt that they should be recognized as complex individuals and challenged eukaryotes to a debate. as prokaryotic bacteria, what arguments would you use to defend your position?
Answer:
prokaryote cells are less structurally complex than eukaryotes, they are more chemically complex, since all of the prokaryote cell's biomolecules are floating around together.
Explanation:
Prokaryotic cells are usually a whole lot smaller and greater simple than eukaryotic. Prokaryotic cells are, in fact, able to be structurally extra truly because of their small length. The smaller a cell, the extra its floor-to-quantity ratio (the surface region of mobile compared to its quantity
What are prokaryotes and eukaryotes?Prokaryotes are organisms made from cells that lack a mobile nucleus or any membrane-encased organelles. Eukaryotes are organisms made of cells that possess a membrane-bound nucleus that holds genetic material in addition to membrane-certain organelles

How do you know if something is alive? Please help me describe some of the characteristics of living things.
Thanks!
Answer:
In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.

A polar molecule is one which
Answer:
Explanation:
A polar molecule has a net dipole as a result of the opposing charges (i.e. having partial positive and partial negative charges) from polar bonds arranged asymmetrically. Water (H2O) is an example of a polar molecule since it has a slight positive charge on one side and a slight negative charge on the other.
how does the nucleus works with the lysosomes
Answer:
Lysosome, subcellular organelle that is found in nearly all types of eukaryotic cells (cells with a clearly defined nucleus) and that is responsible for the digestion of macromolecules, old cell parts, and microorganisms.

The nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes. Mitochondria are responsible for ATP production; the endoplasmic reticulum modifies proteins and synthesizes lipids; and the golgi apparatus is where the sorting of lipids and proteins takes place.

What does an inhibitor do ?
Answer:
Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. An inhibitor can bind to an enzyme and stop a substrate from entering the enzyme's active site and/or prevent the enzyme from catalyzing a chemical reaction. There are two categories of inhibitors.

What is the structure of minerals?Some elements can be found in nature in their pure state, not combined with other elements. Minerals also include substances like copper, silver, and gold.
Additionally, minerals have a distinct chemical makeup with an ordered atomic arrangement known as a crystalline structure.
Chemical composition, crystal structure, and physical characteristics. quartz, feldspar, mica, amphibole, olivine, and calcite are examples of common minerals.
Therefore, a mineral is an inorganic element or compound that occurs in nature having a crystal structure.

Explain why all the water on earth is the same water that was on earth 12,000 years ago when the last Ice Age ended.
Answer:
Because if the water cycle
Explanation:
They water cycle just is a cycle that reuses the water over and over again. Although the water light come from somewhere else in the world it is still the same water
The water cycle is simply a cycle that reuses water over and over. As this water cycle helps to circulate water throughout the environment.
What is water cycle?The water cycle is a biogeochemical cycle that describes the continuous movement of water on, above, and below the Earth's surface. It is also known as the hydrologic cycle or the hydrological cycle.
Evaporation, condensation, and precipitation are the three major processes in the water cycle.
Evaporation is the process by which the surface of a liquid changes to a gas. Liquid water (in the ocean, lakes, or rivers) evaporates and turns into water vapor during the water cycle.
The hydrologic cycle is critical because it determines how water reaches plants, animals, and humans.
Addition to offering water for people, animals, and plants, it also shuttles nutrients, pathogenic organisms, and silt into and out of marine ecosystems.
Thus, it can be concluded that the water on the Earth is same as it was on earth 12,000 years ago when the last Ice Age ended.

Describe hydrolysis and dehydration synthesis reactions in regards to macromolecules
and water
Answer:
Explanation:
In dehydration synthesis reactions, a water molecule is formed as a result of generating a covalent bond between two monomeric components in a larger polymer. In hydrolysis reactions, a water molecule is consumed as a result of breaking the covalent bond holding together two components of a polymer.
Mature red blood cells expel their nuclei so that they have more surface area to transport oxygen and
carbon dioxide. What does this demonstrate?
O A. They cannot live very long.
о
B. They must die within 24 hours.
OC. They are beginning to show signs of cancer.
o
D. They are unable to metabolize or produce ATP.
Answer:
The fact that mature red blood cells expel their nuclei, to expand their surface area and transport oxygen, can demonstrate that they cannot live very long.
Explanation:
The absence of a nucleus in mature red blood cells (erythrocytes) means that it has no genetic material and is unable to synthesize proteins to repair itself. This means a relatively short half-life for these cells.
A mature red blood cell circulates in the blood and performs its function for about 90 to 120 days, after which it is eliminated.
Regarding the other options:
B. Red blood cells can live more than 24 hours.
C. The absence of a nucleus in erythrocytes does not indicate any relationship with cancer.
D. Although they do not have mitochondria, erythrocytes can obtain ATP by glucose glycolysis and lactic acid fermentation. Even so, it is not related to the lack of nucleus

Which of the following statements most accurately describes the difference between an ionic bond and a covalent bond?
O Atoms held together by ionic bonds separate when placed in water, while atoms held together by covalent bonds do not separate in water.
Electrons are exchanged between atoms held together by an ionic bond, but they are shared between atoms held together by a covalent bond.
O lonic bonds hold together atoms of two different types, while covalent bonds hold together atoms of the same type.
O lonic bonds form between atoms that carry opposite charges, while covalent bonds form between uncharged atoms.
Answer:
Answer is lonic bonds hold together atoms of two different types, while covalent bonds hold together atoms of the same type.
lonic bonds hold together atoms of two different types, while covalent bonds hold together atoms of the same type. So, the correct option is (C).
What are Ionic and Covalent bonds?There are two forms of bonding in which an atom can participate which are as follows:
Covalent bondIonic bondCovalent bond is defined as involving the sharing of electrons between two or more atoms while ionic bond is defined as the formation when two or more ions come together and are held together by charge difference.
Ionic bonds form with atoms with a greater electronegativity difference, for example NaCl whereas covalent bonds form with the electronegativity of the combining atoms not much different from the bond formed between them, for example HCl
Thus, lonic bonds hold together atoms of two different types, while covalent bonds hold together atoms of the same type. So, the correct option is (C).
