What system do we use to bind periods, eras, etc., of time together?
Answer:
The Geological Time Scale
Explanation:
The Geological Time Scale is the framework in which the history of the Earth is inscribed. It combines a numerical scale that uses the million years as a unit (chronometric scale) and a scale that is expressed in relative time units (chronostratigraphic scale).
The chronometric scale is based on the measurement of certain physical properties of rocks, generally the relationship between the content of stable and unstable isotopes of the same element.
restriction enzymes cut DNA at totally random places. true of false?
Answer:
False
Explanation:
Restriction enzymes, also called restriction endonucleases, are enzymes found in bacteria that cut DNA. They recognise target sequences and cut DNA at or near these sequences. These sequences are called restriction sites.
They act as a defense mechanism against invading pathogens. However, they are routinely used in molecular biology labs to perform DNA technologies such as genetic engineering.

What is the source of oxygen as a reactant in cellular respiration?
Answer:
The Reactants
What goes into the cell? Oxygen and glucose are both reactants of cellular respiration. Oxygen enters the body when an organism breathes. Glucose enters the body when an organism eats.
Explanation:
Hope this helped, Thanks :)
Cellular respiration has been the chemical process that uses glucose to produce energy. Oxygen is the reactant of the process that comes from the air (breathing) produced by photosynthesis.
What is cellular respiration?Cellular respiration has been defined as the process vital for living organisms that use oxygen and sugar molecules to produce energy to drive the activities and functions of the body. The reactant of the process includes glucose and oxygen gas.
Oxygen and sugar are known to be the product of the photosynthetic reaction that uses carbon dioxide and water. The oxygen gas is present in the atmosphere and enters the body through breathing.
Therefore, oxygen acts as a reactant in cellular respiration that comes from the breathing process.

Answer:
C. The salt is dissolved by the water
Explanation:
When ionic compounds dissolve in water, the individual ions separate and get surrounded by water molecules—a process called solvation. Because the salt ions are charged, they dissolve much better in a polar solvent, which is also slightly more charged than a nonpolar solvent

Molecules that make up living things and contain carbon are called __________ molecules.
Molecules that make up living things and contain carbon are called organic molecules.
Organic molecules are those that derive their three-dimensional configurations primarily from their carbon skeletons.
Organic molecules are essential for the birth, development and functioning of all cells that make up living organisms.
About organic molecules:
All organic molecules contain carbon and practically always hydrogen, it is also frequent that they have oxygen or nitrogen.These chemical elements enable multiple and covalent bonds to be established, allow carbon atoms to develop three-dimensional skeletons, and give rise to multiple functional groups. Proteins, vitamins, carbohydrates, lipids, and nucleic acids are organic biomolecules, which are synthesized by living organisms.Therefore, we can conclude that molecules that make up living things and contain carbon are called organic molecules, which a living being needs to develop normally.

Running for a long period of time, such as during a marathon, can result in muscle fatigue. Which process is important to a runner at the end of a marathon?
A. lactic acid fermentation to produce ATP without oxygen
B. Alchoholic fermentation to release carbon dioxide
C. The Krebs cycle to produce NADH and FADH2
D. The electron transport chain to produce ATP
The process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).
Cellular respiration refers to the reactions by which aerobic cells normally produce energy in the form of ATP by using energy stored in the chemical bonds of foods and oxygen.Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).Acid lactic fermentation is energetically much less efficient than cellular respiration, but ATP production in cellular respiration is much slower than in fermentation, thereby muscle cells use this pathway (fermentation) when they cannot get oxygen fast enough to meet their energy requirement.In conclusion, the process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).

Compare and contrast the TWO classes of "seeded "plants.
Answer:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not.
Explanation:
The seed plants are often divided arbitrarily into two groups: the gymnosperms and the angiosperms. The basis for this distinction is that angiosperms produce flowers, while the gymnosperms do not. This is poor form, since it defines the gymnosperms by the absence of a character, and not by any features that the organisms actually share. The gymnosperms do share a number of features, but, as should be obvious from the above cladogram, they are not more closely related to each other than to the angiosperms (Anthophyta). The features shared by gymnosperms were likely present in the early ancestors of the flowering plants as well. It should also be noted that the "progymnosperms" are represented by a box of a different color, in order to make it clear that they are not actually seed plants, but rather are included here because they are believed to be the closest relatives of the seed plants.
Systematics within the seed plants is poorly understood. Part of the problem is that most of the major groups have gone extinct, and several of the groups alive today consist primarily of plants with highly derived morphologies. The above cladogram is based largely on the work of Jim Doyle, a professor at UC Davis, and Michael Donoghue, currently at Harvard, and is therefore somewhat preliminary. It includes some questionable groupings not explicitly supported in their papers.
how do skin cells replace itself after an injury?
a) skin cells go through the process of budding to make new identical cells.
b) skin cells go through the procces of mitosis to make new identical cells.
c) skin cells go through the process og photosynthesis to make new identical cells.
d) skin cells go through the process of cellular respiration to make new identical cells.
Answer:
d
Explanation:
as a result of accumulation of waste products in the body , these substances are removed from the body via the skin hence they undergo cellular respiration
Answer:
b) skin cells go through the process of mitosis to make new identical cells.
Explanation:
The skin is the largest organ in the human body; it forms a protective barrier that keeps out external pathogens, and is integral to waste removal. When the organ is injured, damaged cells initiate an immune response, while healthy cells nearby begin to replicate.
This type of cell replication involves somatic cells and results in the diploid number of chromosomes called mitosis. Skin cells are somatic- they contain all 24 pairs of human chromosomes. During replication, the chromosomes are unwound, and copied- then, the newly copied chromosomes separate into two identical daughter cells with the same chromosome number.
