How many groups are in the modern periodic table?
Answer:
18
Explanation:
there are 18 numbered groups in the periodic table;The F-block columns (Between groups 3 and group 4) are not numbered.
There are 18 groups in the modern periodic table.
How do we explain?The groups are numbered from 1 to 18, and they are also referred to as groups A and B.
Groups A are the main groups, and they contain elements that have the same number of valence electrons. Groups B are the transition groups, and they contain elements that have a variable number of valence electrons.
The modern periodic table is organized by the atomic number of the elements. The atomic number is the number of protons in the nucleus of an atom. The elements are arranged in order of increasing atomic number, and they are grouped together based on their chemical properties.

A. The older, denser crust subducts
B. Mountains grow upward
C. Volcanoes grow and erupt

I say A- Older Denser Crust Subduct
As Time pass, Older Crust gets denser. When it reaches the end of its life, it goes under the newer crust. This is called Subduction. (new Vocanoes do form and sometimes erupt)
Organisms require nitrogen to make which of the following?
Answer:
amino acids
Explanation:
All organisms require nitrogen to make amino acids, which in turn are used to build proteins.
Nitrogen is required by living organisms to synthesize amino acids. These amino acids unite to form polymers which make proteins.
What are Amino acids?Amino acids are the organic compounds which contain both the amino and carboxylic acid functional groups in it. This is reason, these acids are called amphipathic acids. Although hundreds of amino acids still exist in nature, by far the most important acids are the alpha-amino acids, which comprise proteins. There are only 22 alpha amino acids which appear in the genetic code.
In the structure of an amino acid, the R represents a side chain specific to each amino acid. The carbon atom next to the carboxyl group is called the α–carbon atom. Amino acids which contain an amino group bonded directly to the α-carbon are referred to as the α-amino acids.

If the DNA is TAG what will be the amino acid?
If the RNA is UAU what will the amino acid be?
Leucine
Aspartic acid
Histidine
If the DNA is GAT what will be the amino acid?
Answer-Leucine
If the DNA is TAG what will be the amino acid be?
Answer-Isoleucine
If the RNA is UAU what will the amino acid be?
Answer-Tyrosine
The genetic code contains the STOP codons UAG, UAA, and UGA. These codons serve as a marker for the end of the polypeptide chain during translation.Because they do not encode an amino acid, these codons are often known as nonsense or termination codons.
What are the amino acid in the genetic code?Codons are trinucleotide based units of genetic information found in DNA or RNA that either code for a particular amino acid or signal the completion of protein production (stop signals). There are 64 different codons, of which 61 identify amino acids and 3 act as stop signals.
Therefore, If the DNA is GAT what will be the amino acid-Leucine. If the DNA is TAG what will be the amino acid be -Isoleucine. If the RNA is UAU what will the amino acid be-Tyrosine.

Answer:
Hey the question isn't clearly visible
but the picture explains the Nytrogen cycle
Explanation:
The water droplets/rain dissolves the fertilizers and make it easier for the plant to suck it.The bacteria present in the roots of the plant takes up the nitrogen and helps the plant to grow.The cow eats the plant and the nitrogen is in the cow's body.After some years the cow dies and its body is eaten up by animals and when it decays, the nitrogen in its body mixes with the earth and thus is taken up by plants and used. The plant gives out air and vapours containing nitrogen through transpiration and other processes which then results in the release and mixing of nitrogen with other gases and thus resulting in rain.Hope you got it... :)

You are trying to see who can stay underwater the longest. You stayed under for 48 seconds! When you come up for air, you take a big breath. Your cells need oxygen so they can release energy so you can keep swimming. Explain all the parts of the cell involved in getting oxygen into your cells so it can help release energy.
Answer:
All the parts of the cell involved in getting oxygen into your cells so it can help release energy are Mitochondria , Ribosomes ,Peroxisomes and Vesicles.
Explanation: Explaination of all four parts of the cell involved in getting oxygen into our cells so it can help release energy-
MITOCHONDRIA -:"Mitochondria (singular = mitochondrion) are also referred to as a cell's" powerhouses "or" energy factories "because they are responsible for producing the main energy-carrying molecule of the cell, adenosine triphosphate ( ATP). ATP reflects the cell's short-term stored energy. The method of producing ATP using the chemical energy found in glucose and other nutrients is cellular respiration. This method utilizes oxygen in mitochondria and creates carbon dioxide as a waste product.RIBOSOMES -: The cellular structures responsible for protein synthesis are ribosomes. Ribosomes appear either as clusters (polyribosomes) or single, tiny dots floating freely in the cytoplasm when viewed through an electron microscope. They can be connected to the plasma membrane's cytoplasmic side, or to the endoplasmic reticulum's cytoplasmic side and the nuclear envelope's outer membrane.PEROXISOMES -:Peroxisomes are specialized for the use of molecular oxygen to conduct oxidative reactions. They produce hydrogen peroxide, which they use for oxidative purposes, by means of the catalase they contain, removing the excess.VESICLES -: A byproduct of the transformation of vesicles is oxygen. Also, Prochlorococcus develops a large number of vesicles that are used for many important functions: virus protection, genetic information transfer, and nutrient transmission. Via a number of pathways, all cells generate vesicles.Hence , the parts of the cell involved in getting oxygen into our cells so it can release energy are mitochondria (the main part), ribosomes ,peroxisomes and vesicles.

By looking at a map, how can you tell where the profile will be the steepest in a topographic map?
Answer:
The contour lines will be closest together.
Explanation:
When contour lines are closer together, the slope is steep. When contour lines are farther apart, the slope is gentle. This is because contour lines indicate altitude. The closer the contour lines, the faster the increase in altitude, and therefore the steeper the slope.

How does a decrease/decline in a top predator impact biodiversity in an ecosystem?
Answer:
Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species
Please find the explanation below
Explanation:
In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.
A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.
Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.
