what kind of mutation does this image represent
Answer:
A. Deletion
Explanation:
The kind of mutation that this image represent is deletion. The correct option is A.
What is mutation?A variation in the usual DNA sequence at a specific gene locus. Although the term has a negative connotation, mutations (including polymorphisms) can have a negative, positive, or neutral effect on cell function.
Mutations can occur as a result of errors in DNA replication during cell division, mutagen exposure, or viral infection.
Germline mutations (those found in eggs and sperm) can be passed on to offspring, whereas somatic mutations cannot.
In genomics, a deletion is a type of mutation that involves the removal of one or more nucleotides from a segment of DNA. A deletion can result in the loss of any number of nucleotides, ranging from a single nucleotide to an entire chromosome.
Thus, the correct option is A.

4. Describe the large-scale change that occurred at Coldwater Creek after the eruption. What effect would this have had on the local ecosystem?
The gases and dust that the volcanic eruption releases changes the climate because most particles erupted shade incoming solar radiation causing the global climate to cool down.
What are the different ways to recover grassland ecosystem after volcanic revolution?The volcanic eruption destroys a grassland ecosystem. They burns the place and the plants. The dusts cover up the leaves and the heat kills the seeds and spores of the plants. The recovery isn’t easy and fast.
As the volcano lava cools and subsides, the new vegetation starts to grow.
The seeds are brought by the wind, birds and other animals that are spread over the landform. The rain provides the necessary water for germination. Volcano supplies the necessary minerals that are very good for plant growth.Thus, most particles erupted shade incoming solar radiation causing the global climate to cool down.

What should scientists do when a new discovery is made that goes against a long-accepted theory?
He should analyze and compare his findings with findings already accepted within the scientific community.
What is theory?A theory is a well-substantiated explanation of an aspect of the natural world that can incorporate laws, hypotheses and facts.
A theory not only explains known facts as it also allows scientists to make predictions of what they should observe if a theory is true. Scientific theories are testable. New evidence should be compatible with a theory. If it isn't, the theory is refined or rejected. The longer the central elements of a theory hold the more observations it predicts, the more tests it passes, the more facts it explains the stronger the theory.

3. In the Pacific Ocean, there is a plate boundary between two tectonic plates: the Pacific Plate, which contains some of
the oldest oceanic crust on Earth, and the Mariana Plate. The Mariana Trench, the deepest oceanic trench on Earth,
is located at this boundary. Nearby, there is an arc of volcanic islands called the Mariana Islands. Based on this
information, what type of plate boundary is this? How do you know?
Ocean trenches are long, narrow depressions on the seafloor. These chasms are the deepest parts of the ocean—and some of the deepest natural spots on Earth.
There are different types of plate boundaries based on the movement of tectonic plates. The plate boundary in which a line of volcanic islands are present is called convergent plate boundary.
What is plate boundary?Plate boundary is the inter-region between two tectonic plates. The magma in the crest when undergo convection process and flow of this heated magma causes the movement of tectonic plates.
Based on the movement and sliding of the plates above the other there are three types of plate boundaries namely, divergent, convergent and transform plate boundaries.
Divergent plate boundaries originates when the plates moves apart these type of plate boundaries have the volcanic activities and shallow earth quake.
Convergent plate boundaries are where, the plates are moving edge to edge manner each other manner and buckles up to mountain. Convergent plate boundaries create the a chain of volcanoes parallel to the plates.
Transform plate boundary is created by plates sliding past each other which forms no volcanoes. Hence, the volcanic islands are in convergent plate boundary.

what is inside your capillaries that carries oxygen to your heart?
Answer:
Capillaries are narrow blood vessels. Blood contains plasma, red blood cells, white blood cells and platelets. Red Blood cells are bi-concave disc which contains hemoglobin that reacts with oxygen and thus oxygen is transported by RBC to the heart where it is distributed to the whole body
Veins are present inside your capillaries that carry oxygen to your heart. While arteries perform the opposite function which carries blood away from the heart.
What are the functions of capillaries?The functions of capillaries are as follows:
Capillaries transport blood, oxygen, and nutrients to every cell. They are the type of delicate blood vessels that exist throughout your body. They also exchange waste throughout the body.Capillaries also help in the connection of arteries and veins.Capillaries are the connection link of both arteries and veins. So, both arteries and veins perform their specific function in order to facilitate the transport of deoxygenated blood and oxygenated blood to and from the heart respectively.
Therefore, the structure inside your capillaries that carries oxygen to your heart is known as veins.

How are the hip bones in a frog different from the human pelvis?.
Answer:
Just like in a person's arms, in a frog's front legs are bones called the humerus, the radius and the ulna. However, a frog's radius and ulna are fused into one bone. The same is true for a frog's legs -- the femur supports its upper leg, and the bones of the lower leg, the tibia and fibula, are fused.
The frog's larger back legs consist of a femur as the strong, upper leg support, just like in humans, albeit on a different-sized scale. The back legs also consist of a fibula, as well as tibia; however, on the frog these two bones are fused together into one.

What is the net result of one glucose molecule going through the krebs cycle.
Answer:
Recall that glycolysis, stage I of cellular respiration, produces two molecules of pyruvate. These molecules enter the matrix of a mitochondrion, where they start the Krebs cycle.
Two molecules of pyruvate are produced during the first stage of cellular respiration, glycolysis. These substances enter a mitochondrion's matrix, where they initiate the Krebs cycle.
Thus, A little quantity of ATP (adenosine triphosphate) is produced by the Krebs cycle through substrate-level phosphorylation. Two ATP molecules are directly created in the Krebs cycle for every glucose molecule.
Electron transport chain (ETC): The Krebs cycle also generates high-energy electron carriers called NADH (nicotinamide adenine dinucleotide) and (flavin adenine dinucleotide), which transport the electrons to the ETC for additional ATP generation.
Carbon dioxide is generated as a waste product during the Krebs cycle's breakdown of glucose. Six CO2 molecules are produced overall for every molecule of glucose.
Thus, Two molecules of pyruvate are produced during the first stage of cellular respiration, glycolysis. These substances enter a mitochondrion's matrix, where they initiate the Krebs cycle.
