Explanation:
Recent remains of plants or animals on topsoil are fossils.
The statement 'recent remains of plants or animals on topsoil are fossils' is TRUE about fossils.
What are fossils?Fossils are dead decomposed organisms (either plants or animals) that once lived on the topsoil of the Earth.
The existence of fossils is fundamental for extracting certain fuels of the Earth (e.g., coal is made from dead plants).The fossil record is also fundamental to obtain a piece of evidence for evolutionary mechanisms.In conclusion, the statement 'recent remains of plants or animals on topsoil are fossils' is TRUE about fossils.

why is carbon dioxide is more in exhaled air than in inhaled air
Answer:
Breathed out air includes more carbon dioxide than breathed in air because carbon dioxide is generated in our bodies throughout the breath cycle as a result of food oxidation. As a result, it is expelled from the body upon exhalation.

How is a dolphin fin similar to a dogs leg
Answer:
Dogs and dolphins have a lot in common. Even though these animals may be from different species, and live in entirely different environments, they do share one commonality: they're friendly and curious. Both dogs and dolphins will be the first to investigate a new person or situation
Explanation:
The dolphin fin is similar to a dog's leg in the following ways: Both are used for movement.
What are the use of dolphin's fins?The dolphin fin helps the dolphin to swim and navigate in water, while the dog's leg is used for walking and running. Both are composed of bone and muscle. The dolphin fin has a skeletal structure made up of bones and muscles, which allow it to move in different directions. The dog's leg also has a skeletal structure made up of bones and muscles, which allow it to support the dog's weight and move in different directions.
Both are adapted to their respective environments. The dolphin's fin is shaped to help it move quickly and efficiently through water. The dog's leg is adapted to help it run and navigate on land. Both have joints. The dolphin fin has a joint where it connects to the body, which allows it to move in different directions. The dog's leg has joints that allow it to bend and move in different directions.

Polysaccharides, nucleic acids, proteins, and lipids are
that are synthesized from a small collection of basic precursors.
O A
macromolecules
OB.
monomers
Ос
enzymes
Oo
ions
Answer:
Water, organic molecules, and inorganic ions are the constituents of cells. Water constitutes the greatest fraction of the three, accounting for almost three-quarters of the total mass of a cell. The interactions between the various components of a cell and its water content is key to biological chemistry.
Sodium, potassium, magnesium, calcium, phosphate, and chloride, are among the chief inorganic ions of a cell, and represent not more than 1% of the cell mass. But the organic molecules are the really novel components of a cell. Most such organic compounds belong to one of the following molecule classes:
Carbohydrates
Lipids
Nucleic acids
Proteins
Within individual cells, there exist thousands of different types of macromolecules, or organic compounds. These will be different, even among the cells of the same person. The variations are more extensive among different people. Macromolecules - proteins, nucleic acids, and polysaccharides - are formed by the polymerization of hundreds of their low-molecular-weight precursors - amino acids, nucleotides, and simple sugars.
The diversity among macromolecules evolves from the vast potential to form different combinations of the 50 or so common monomers which make up a macromolecule. These macromolecules may constitute up to 90% of a cell’s dry weight. It is possible to comprehend the basic chemistry of a cell’s makeup by understanding the functions and structures of the four major types of organic compounds, or macromolecules.
Carbohydrates
Carbohydrates are the basic building materials and nutrients of the body. Simple sugars and polysaccharides compose this group. Glucose is an example of a simple sugar that is an important cellular nutrient. Decomposition of the simple sugars by chemical reaction generates cellular energy as well as initiating the synthesis of other constituents of a cell. The polysaccharides, or complex carbohydrates, represent the form that sugar takes when it is stored. Polysaccharides are the structural components of a cell. Moreover, polysaccharides and other sugars may function as markers for certain cellular recognition processes, including the intracellular movement of proteins.
Lipids
Lipids are hydrophobic molecules. They are a highly efficient form of energy storage, and are major constituents of the cell membrane. They are important in cell signaling, function as the starting point for various biosynthetic processes such as the synthesis of estrogen and testosterone. Some lipids are able to convey signals from cell surface receptors to targets in the same or other cells. Phospholipids contain two fatty acids joined to a polar head group. Besides the phospholipids, cells have glycolipids and cholesterol.
Nucleic acids
Nucleic acids store and transmit hereditary data. DNA and RNA represent the informational molecules of a cell. DNA plays a crucial role as the genetic material of humans and many other species. RNA takes part in various cellular activities. Messenger RNA (mRNA) transports information from DNA to the ribosomes, where they are involved in synthesizing proteins. In addition, ribosomal RNA and transfer RNA are involved in protein synthesis. Other RNA molecules process and move both proteins and RNA. RNA can also catalyze chemical reactions, such as those involving the synthesis of proteins and the processing of RNA.
Proteins
Proteins play an important role in most of the tasks that an organism performs. Proteins carry out the work of a cell, directed by the genetic information carried by the nucleic acids. A cell holds many thousands of proteins, which function as a cell’s structural elements, storing and transporting small molecules, transmitting data among cells, and defending the body against the onset of infections. But proteins also function as enzymes that accelerate most chemical reactions. In this manner, proteins guide most cellular activities.

What experiment led directly to Dalton's atomic theory?
Answer:
Dalton's experiments on gases led to his discovery that the total pressure of a mixture of gases amounted to the sum of the partial pressures that each individual gas exerted while occupying the same space. In 1803 this scientific principle officially came to be known as Dalton's Law of Partial Pressures.

Explanation:
Everything that is produced goes through these five main stages:
1.) material extraction
2.) manufacturing
3.) packaging
4.) transportation
5.) use and end of life
At each of these stages, there are inputs and outputs, flow-throughs, value losses, and potential gains.

Regions that have similar climate characteristics can be widely spread apart, but typically have which of the following in common?
Varying altitudes and similar precipitation
Corresponding latitudes and continental locations
Corresponding temperature and wind patterns
Similar ocean currents and vegetation
Answer:
B.) Corresponding latitudes and continental locations
Explanation:
I got it right on the test :)
The regions that have similar climate characteristics can be widely spread apart, but typically have corresponding latitudes and continental locations (Option B).
The amount of precipitation and solar radiation largely determine the climatic conditions of a given region.Regions that have similar climate characteristics are found in similar latitudes to receive a similar amount of solar radiation.Moreover, these regions also are found in similar continental locations because it affects the amount of precipitation.In conclusion, regions that have similar climate characteristics can be widely spread apart, but typically have corresponding latitudes and continental locations (Option B).
