Explanation:
Earthquake waves produces two very important waves that useful in studying the composition of the earth.
These waves are P and S-waves.
P-waves are primary longitudinal waves that propagates through any material medium. S-waves are secondary transverse waves that can only pass through solids but not fluids.Using these waves we can know the composition of the earth.
Which of the following is a way ATP is used in cellular processes? Select all that apply.
detoxification
muscle contraction
oxygen production
biosynthesis
polyatomic ions
Answer:
detoxification muscle contraction biosynthesisExplanation:
ATP, adenosine triphosphate, is a molecule high in chemical energy. It is made up of a ribose ring, the nitrogenous base adenine, and 3 phosphate groups in a phosphoester linkage at carbon 5
ATP is broken down, losing a phosphate group, and energy is released from breaking the phosphate bond. The other two phosphates in ADP are lined by stable p hosphoanhydride bonds.
[tex]ATP+H_{2}O[/tex] → [tex]ADP+Pi+free \hspace{0.1cm} energy[/tex]
In the body, ATP molecules are used to provide energy for detoxification in forms of active transport; fueling biosynthesis- the modification of different compounds to form macromolecules; and muscle contraction, providing energy to myosin, and braking myosin actin cross-linkages to free myosin for other contractions.
Which of these organisms would most likely be found at the top of an energy pyramid?
a clams - a primary consumer
b. sardines - a primary consumer
c. sharks - a secondary consumer
d. kelp - a primary producer
The energy pyramid is a diagram that shows the flow of energy between trophic levels in an ecosystem. In an energy pyramid, the energy flows from producers to consumers.
The organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).In an energy pyramid, the energy flows from producers (e.g., plants) to primary consumers (eg., herbivores). Subsequently, the energy then flows from primary consumers to secondary consumers (e.g., carnivores) and so successively.In an energy pyramid, the amount of available energy decreases as it moves through subsequent trophic levels.In conclusion, the organisms that would most likely be found at top of the energy pyramid are sharks (secondary consumers).

How do the chromosomes of an offspring cell compare with the chromosomes of the parent cells?
Answer:
Offspring will usually have half the amount of chromosomes from each parent. For example: Mother Human= 46 Chrom, Father Human= 46 Chrom, Baby Human= 23 Chrom from father and 23 Chrom from mother.
There are just half as many chromosomes. Typically, children inherit half of each parent's chromosomes.
What are chromosomes?As an illustration, the mother and father of a human have 46 chromosomes each, and the baby has 23 chromosomes from each parent.
The sister chromatids reach their opposing poles at this final stage of mitosis. The cell's tiny nuclear vesicles start to reform around the chromosome cluster at each pole. As the process by which the parent cell transfers its DNA to its two daughter cells, mitosis is a crucial component of cell division.
Homologous chromosomes align in pairs during meiosis. Chromosomes are independent of one another during mitosis.
Therefore, half as many chromosomes the chromosomes of an offspring cell compare with the chromosomes of the parent cells.

please help, i’ll mark brainliest if you get it right! please please only answer if you know the answer though, don’t guess i’m taking a test and i can’t fail as it’s the last one before the quarter ends ( tomorrow ) id appreciate it!! thank youuu
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

Besides helping to discover the structure of DNA, describe two other contributions Rosalind Franklin made to the world of science.
Answer: Rosalind Franklin discovered the density of DNA and, more importantly, established that the molecule existed in a helical conformation. Her work to make clearer X-ray patterns of DNA molecules laid the foundation for James Watson and Francis Crick's suggestion that DNA is a double-helix polymer in 1953.
Explanation:
Rosalind Franklin made numerous contributions to science in addition to helping to discover the structure of DNA, and in the field of virology, in coal-based materials, by using X-ray crystallography, in agriculture, etc.
What is the contribution of Rosalind Franklin?She was one of the greatest scientists who made significant contributions to the field of DNA by using X-ray crystallography, and apart from that, she also made contributions to the field of virology. As X-ray diffraction facilitates the study of the structure of viruses such as the tobacco mosaic virus and the polio virus and helps in understanding the replication of viruses, it is also helpful in the study of the structure of coal and other carbon-based materials.

An RNA sequence includes 12 nitrogenous bases, AUGGUGCAUGUC. What is the maximum number of amino acids for which this sequence could code?
A). 4
B). 3
C). 2
D). 12
Answer:
In the mRNA sequence AUGGUGCAUGUC the maximum number of amino acids that can be encoded is 4 (option A).
Explanation:
Messenger RNA (mRNA) has a sequence of nitrogenous bases produced by the transcription of a DNA strand. This sequence of bases is organized in triplets or codons —made up of 3 nitrogenous bases— that can encode an amino acid, or mark the beginning or end —STOP codon—of protein synthesis.
From the sequence:
AUGGUGCAUGUC
Four codons are obtained, each of which encodes a different amino acid:
Codons: AUG-GUG-CAU-GUC
Amino acids: Met - Val - His - Val
Methionine Valine Histidina and Valine are the four amino acids encoded by the 12 nucleotide sequence of the mRNA.

During an infection, white blood cells travel to the infected site and phagocytize the pathogens. After phagocytosis, primary lysosomes fuse with the phagocytic vesicle to form a larger vesicle called a secondary lysosome. The reason for this is:
answer choices
a) to introduce antibodies to the phagocytic vesicles
b) to wrap the pathogen in additional membrane, rendering them harmless
c) to prepare the bacteria for export from the body
d) to mix the pathogens with strong hydrolytic enzymes and destroy them
Answer:
d) to mix the pathogens with strong hydrolytic enzymes and destroy them
Explanation:
phagocytosis occurs when a cell engulfs a molecule to break it down.
white blood cells are known as phagocytes as they ingest invading bacteria to break them down and destroy them.
The bacteria is first enclosed by a phagocytic vesicle that lysosomes fuse with on fusing lysosomes then break down the bacteria by mixing them with strong hydrolytic enzymes.
