What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.

Which statements about geocentric model and heliocentric model are true? Select the two correct answers.
A. They both are models of the solar system.
B. They both show the position of Earth relative to the Sun.
C. They both show Earth at the center of the solar system.
D. They both show the Sun at the center of the solar system.
Answer:
A and B
Explanation:
the other 2 answers are just obviously wrong
They are both models of the solar system and they both show the position of the Earth relative to the sun. So the correct option is A and B.
What are heliocentric and geocentric models?A cosmological concept known as heliocentrism assumes that the Sun is located at or close to the center of the solar system or the universe, with the Earth and other planets revolving around it. The Greek philosophers Philolaus and Hicetas hypothesized independently that the Earth was a rotating sphere that rotated daily around a mysterious "central fire" that controlled the cosmos in the fifth century BC.
Two hundred years later, Aristarchus of Samos expanded on this concept by stating that the Sun, together with the Earth and other planets, revolved around a certain central object.
Any solar system (or universe) structure hypothesis that places Earth at the center of the cosmos is referred to as a geocentric model. Ptolemy of Alexandria's geocentric model was the most advanced (2nd century CE). It was widely believed until the 16th century when heliocentric theories like Nicolaus Copernicus took their place.
Therefore the correct options are A and B.

How do animals help recycle carbon atoms?

Explanation:
Can someone explain to me the carbon cycle and a similar way
Answer:
The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

The Go' for the reaction Citrate Isocitrate is +6.64 kJmol-1 . The Go' for the reaction Isocitrate α-Ketoglutarate is -267 kJmol-1 . Calculate the Go' for the conversion of citrate to α-ketoglutarate?
Answer:
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1
Explanation:
ΔG°' for Citrate is +6.64 kJmol-1
ΔG°' for Isocitrate is -267 kJmol-1
ΔG°' for the conversion of citrate to α-ketoglutarate = ΔG°' for product - ΔG°' for reactant
ΔG°' for the conversion of citrate to α-ketoglutarate = -267 kJmol-1 - (+6.64 kJmol-1)
ΔG°' for the conversion of citrate to α-ketoglutarate = - 273.64 kJmol-1

A drought is a period of unusually low
rainfall. A farmer notices that a well on the farm stops providing water
during a drought. A nearby lake also
has less water in it than usual. Write a
couple of sentences that explains
what has happened to the water table
in the area to cause these results.
In the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.
What is drought?Drought may be defined as a brief period of abnormally dry weather sufficiently prolonged for the lack of water to cause a serious hydrologic imbalance in the affected area.
During severe droughts, people depend heavily on groundwater—the water held underground in aquifers. During these periods, the rainfall is less than normal for several weeks, months, or years, the flow of streams and rivers declines, water levels in lakes and reservoirs fall, and the depth of water in wells gradually increases.
Therefore, in the drought period, the water label usually lowers due to the extreme heat of the sun that forces the water to undergo the process of evaporation and absorb all the water present on the surface.

The human immune system detects the presence of pathogens using pattern recognition receptor molecules that bind to common components of pathogens, such as peptidoglycan polymers in cell walls and the flagellin protein of bacterial flagella, known as pathogen-associated molecular patterns, or PAMPs. These receptors are effective becauseGroup of answer choicesthey detect only human immune molecules.they result in rapid evolution of the host immune system.they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.PAMPs evolve more quickly than other pathogen molecules.
They recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.
What are Pattern recognition receptor molecules?Pattern recognition receptor molecules detect pathogen-associated molecular patterns (PAMPs), which are structurally conserved components of pathogens such as bacteria, viruses, and fungi. These molecules are essential for the survival and function of the pathogen, and are not found in the host's cells.
By recognizing PAMPs, the immune system can quickly identify and respond to a wide range of potential pathogens, without needing to recognize every individual pathogen separately. Therefore, the receptors are effective because they recognize evolutionarily conserved molecules that are structurally essential to the various bacteria that use them.

A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a ___
Answer: A segment of dna/chromosome containing the instructions for building a protein which will result in a trait is called a GENE.
Explanation:
CHROMOSOMES are made up of two threads called chromatids joined at a point called the centromere.
In the chemical nature of chromosomes, each is made up of a protein framework which has a long molecule of DNA (deoxyribonucleic acid) coiled round it. A segment of DNA containing the instructions for building a protein which will result in a trait is called a GENE.
The GENES in the cell of a diploid organism contain all the necessary instructions for building up the organism.These instructions are written on a molecular scale.. Most genes contain information to direct the synthesis of specific proteins. Each such protein takes part in the development of a particular character.
A protein is made up of one or more chains of amino acids known as polypeptides. The sequence of bases in a DNA molecule determines the type of amino acid and the sequence in which they are arranged in a polypeptide chain.
A gene therefore is a sequence of triplets of the four bases which specifies the structure of a protein
