Explanation:
biological macromolecules are organized into four main categories. What type of macromolecule contains phosphorus as part of a phosphate group?
1.) lipids
2.) proteins
3.) nucleic acid
4.) carbohydrates
Answer:
3.) nucleic acid
Explanation:
Biological macromolecules can be defined as a very large molecule (structure) that comprises of covalently bonded organic atoms and smaller molecular structures (monomers).
Biological macromolecules are organized into four main categories and these includes;
I. Lipids: these categories of biological molecules is mainly made up of fats and it is responsible for providing the body with long-term energy.
II. Carbohydrates: it is contained in energy-giving foods and it aids the functioning of the muscles, nervous system and other organs found in the body.
III. Proteins: it contains amino acids and it is responsible for maintaining the functioning of the body system.
IV. Nucleic acid: it comprises of deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) which are the genetic codes (blueprints) for living organisms.
Hence, the type of macromolecule that contains phosphorus as part of a phosphate group (sugar 2-deoxyribose) is nucleic acid.
From the biological macromolecules, Nucleic acids contains phosphorus as part of a phosphate group.
Nucleic acids are biopolymers, macromolecules, crucial for all known types of life. Nucleotides, which are the monomer components, make up their structure. a sugar with five carbons, a phosphate group, and a base with nitrogen. Deoxyribonucleic acid and ribonucleic acid are the two main types of nucleic acids.
Deoxyribonucleic acid (DNA) and ribonucleic acid (RNA) are two types of nucleic acids that carry genetic information that is read by cells to create the RNA and proteins that allow living things to function.

In mature animals when do cells still need to differentiate?
Answer:
As an organism develops, cells differentiate to form different types of cells. Most types of animal cell differentiate at an early stage. Many types of plant cells retain the ability to differentiate throughout life. In mature animals, cell division is mainly restricted to repair and replacement.
Explanation:
''.''
In mature animals cells differentiate during : Repair and replacement of animal cells
Cells differentiate in organisms and plants to create more cell types, as the organism and plants continue to mature. While cell differentiation in animals occur mostly before maturity, plants cells continue to differentiate until they die.
While in mature animals, cells differentiates at maturity only when the cells of the mature animal needs repair or replacement due to damage caused to the a cell or tissue.
Hence we can conclude that in mature animals cells differentiate during repair and replacement of cells.

Explanation:
Which is not a likely economic tool to address environmental issues?
Emissions fees and taxes
Responsibility for a product from production to disposal
Small business liability relief
Defunding government regulation
Explanation:
Policy-makers have two broad types of instruments available for changing consumption and production habits in society. They can use traditional regulatory approaches (sometimes referred to as command-and-control approaches) that set specific standards across polluters, or they can use economic incentive or market-based policies that rely on market forces to correct for producer and consumer behavior. Incentives are extensively discussed in several EPA reports
Two basic types of traditional regulatory approaches exist. The first, a technology or design standard, mandates specific control technologies or production processes that polluters must use to meet an emissions standard. The second, a performance-based standard, also requires that polluters meet an emissions standard, but allows the polluters to choose any available method to meet that standard. Performance-based standards that are technology-based, for example, do not specify a particular technology, but rather consider what available and affordable technologies can achieve when establishing a limit on emissions. At times, EPA may completely ban or phase out the use or production of a particular product or pollutant, as it has done with chlorofluorocarbons (CFCs) and certain pesticides. Regulations can be uniform or can vary according to size of the polluting entity, production processes, or similar factors. Regulations are often tailored in this manner so that similar regulated entities are treated equally. MARK AS BRAINLIEST IF IT HELPS

This means that cells that currently exist are capable of creating more cells, however it’s a slow process
Look at the graph below. A graph is shown with Absolute magnitude shown on y axis and Surface temperature in degree Celsius shown on x axis. The Dwarf stars are shown along a slanting line from coordinates 30,000 and minus 3 to 10,000 and minus 4. The Main Sequence stars are shown along a slanting line from coordinates 20,000 and minus 2 to 2,000 and minus 6. The giants are shown along a line parallel to the x axis from coordinates 5,000 and 2 to 2,000 and 3. The supergiants are shown along a line parallel to the x axis from coordinates 7,500 and 4 to 2,500 and 4. Point A has coordinates 20,000 and minus 4. Point B has coordinates 2,500 and minus 4. Point C has coordinates 5,000 and 2. Point D has coordinates 7,000 and 4. Which of the following stars is most likely to be red? Star A Star B Star C Star D
Answer:
Star A
Explanation:
If you look directly at the diagram, the dwarf stars are labeled under 'A' and are the least in mass and temperature.
Being the smallest and coldest, dwarf stars most commonly have red coloration, which would make them the obvious choice.
Star A which is a dwarf star has the coldest temperature, and therefore is a red star since red stars are the coldest stars.
What are stars?Stars are a large self-luminous bodies whichbpriducw large amounts of heat energy and light energy as a result of the nuclear reactions occurring within them.
Stars have different colors and different sizes.
Red stars are the coldest stars and also the least massive.
From the chart, Star A which is a dwarf star has the coldest temperature, and therefore is a red star.

explain how the equilibrium price is determined
Answer:
The equilibrium price is the price at which the quantity demanded equals the quantity supplied. It is determined by the intersection of the demand and supply curves. .
A decrease in demand will cause the equilibrium price to fall; quantity supplied will decrease.
Explanation:
Electron transport from complex I to complex IV pumps more protons than transport from complex II to complex IV.
With this in mind, which will produce more ATP
A. Transport from complex I produces more ATP.
B. Transport from complex II produces more ATP.
C. Both produce the same amount of ATP.
Answer:
A
Explanation:
ATP synthase uses a proton gradient to make ATP. Since transport from complex I creates a larger proton gradient, it also produces more ATP.
Electron transport from complex I produces more ATP.
ELECTRON TRANSPORT CHAIN:
The electron transport chain, ETC, is the third and last stage of aerobic cellular respiration. It produces the highest molecules of ATP in cellular respiration. The ETC involves the transfer of electrons to series of molecules in order to create an electrochemical gradient needed for ATP synthesis. The electron transport chain is made up of four complexes namely: Complex I, II, III and IV. NADH and FADH2 produced in the Krebs cycle are the electron carriers. Complex I pumps more hydrogen ions (H+) from the mitochondrial matrix to the intermembrane space. Since the pumped is directly related to the number of ATP molecules, complex I will produce more ATP molecules.Learn more: https://brainly.com/question/442662?referrer=searchResults

What are the three main classifications that describe galaxies? By what one visible
characteristic do scientists categorize galaxies?
Answer:
Spiral Galaxies, Elliptical Galaxies & Irregular Galaxies
Explanation:
How did galaxies originate? Astronomers believe that after the big bang, the explosion which began the universe 10 billion to 20 billion years ago, gravity began to compress masses of free-floating gas. Two main theories, bottom-up and top-down, explain what happened next. According to bottom-up theories, clusters began to form and assembled together into the larger units we know as galaxies. Top-down theories suggest that galaxies formed first, and the stars and other objects within them were subsequently produced. They categorized different galaxies to maintain their tests from the other galaxies.
