A family goes on a walk beside a large river. What would most likely happen to the river if the oceans did not exist?
A) The river would get larger because it would snow and hail more often.
B) The river would get smaller because there would not be as much precipitation.
C) The river would get larger because there would be less evaporation.
Answer:
The answer would be B.
Explanation:
Rivers are often filled directly from the ocean and from precipitation.
What are the factors that influence the saltiness of water?
Answer:
Evaporation. Evaporation can only take away water volume, not salt content. Hot air around.
Rivers. Rivers can dilute the salt concentration of an ocean. If there are numerous rivers.
Ocean Currents. Function of Ocean currents are responsible in both increasing and.
Ice Formation. The formation of ice takes away most of the fresh water from the ocean.

-DNA contains chromosomes.
-The same number of chromosomes appears in haploid and body cells.
-Chromosomes contain DNA.
-Chromosomes are found in sets of three.
5. Which modification affects an organism’s expressed characteristics while leaving its DNA sequence unchanged?(1 point)
-insertion mutation
-substitution mutation
-deletion mutation
-epigenetic change
Answer:
100% correct if you use the answers below :)
Explanation:
1. AGC TTT CG
2. CCA TAA CT
3. deletion
4. Chromosomes contain DNA
5. epigenetic change
A frameshift mutation involves the insertion or deletion of nucleotides in a DNA sequence, which modifies its open reading frame. A deletion is a mutation that involves the elimination of one nucleotide in DNA sequence.
With regard to the questions above described:
1. The sequence AGC TTT CG suffered a deletion of the Adenine (A) base at the second codon (i.e., AGC TTA TCG).2. The sequence CCA TAG CT exhibits a deletion of the Cytosine (C) base at the first codon (i.e., CCC ATA GCT).3. Cystic fibrosis is a recessive inherited disorder caused by a three-nucleotide (codon) deletion in the CF transmembrane conductance regulator (CFTR) gene. This deletion is associated with the loss of phenylalanine (Phe) amino acid in the exon 10 of the CFTR gene.4. The statement 'chromosomes contain DNA' is TRUE. Chromosomes are thread-like structures that contain part or all of the genetic material (DNA) of an organism.5. Epigenetic changes are modifications that affect an organism’s phenotype while leaving its DNA sequence. Epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation).In conclusion, frameshift mutations involve the modification of the Open Reading Frame. Deletion involves the elimination of a nucleotide in DNA. Chromosomes are thread-like structures that contain genetic material. Epigenetic modifications don't modify the genetic (nucleotide) sequence.

Explanation:
Speciation can be driven by evolution, which is a process that results in the accumulation of many small genetic changes called mutations in a population over a long period of time. ... Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.
A 30-year old woman was diagnosed with breast cancer. Which of the following processes that we learned
about today would be helpful to her in treating her cancer, and why?
Selective breeding, because she could be sure her children have no risk whatsoever of also getting breast
cancer.
Gene therapy, because it could actively target the cancer cells in her body as a treatment.
Artificial selection, because it could change her DNA so that she is not prone to breast cancer.

Ocean acidification is occurring because
A. of agricultural runoff into rivers.
B. the ocean absorb about 25% of the carbon dioxide emitted into the atmosphere by human activities.
C. water changes pH as it warms.
D. overfishing is changing the structure of ecosystems, haring the plankton that regulate the pH of ocean water.
E. acid rain has worsened over the last two decades.
Answer: b
Explanation:
Its b because Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
Monosaccharides and amino acids are both monomers. These monomers are formed by
hydrolysis. Which statement correctly identifies a difference in the structure of
monosaccharides and amino acids? *
A)Only amino acids contain cytosine, adenine, guanine, and thymine,
B)Only amino acids join together with peptide bonds to form proteins.
C)Only monosaccharides contain carbon and hydrogen.
Answer:
B: only amino acids join together with peptide bonds to form proteins.
Amino acids are glycine and leucine, which are composed of carbon, hydrogen, oxygen, and nitrogen. Carbon, hydrogen, and oxygen make up carbohydrates, which can be either little or big molecules, hence option B is correct.
What is the difference between monosaccharides and amino acids?
The building blocks that makeup proteins are polymeric molecules made up of a chain of amino acids. The biological role of galactose, mannose, fructose and ribose is also significant.
The most prevalent monosaccharide in living things is glucose, which also serves as a structural support system and an enzyme to catalyze chemical processes.
Therefore, the amino group of the additional amino acid creates a peptide bond with the polymer's carboxylic acid group, hence option B is correct.

Humans affect Earth in many ways. The use of fossil fuels, the clear-cutting of forests, and controlled burns can affect the carbon cycle. Which process can help counteract these human interactions? photosynthesis respiration decomposition transpiration
Answer:
Photosynthesis
Explanation:
Photosynthesis takes in CO2 from the atmosphere and utilizes it to form sugars/oxygen.
The equation: 6CO2+6H2O -> C6H12O6 + O2
Respiration will do the opposite and actually release CO2 into the atmosphere
Decomposition will also release CO2 as a byproduct
Transpiration I don't believe has anything to do with removing or putting CO2 into the atmosphere. It's about water movement!
