You discover a new type of marine organism that has the kidneys of a fish but no gills. Based on what you know about other aquatic organisms, the newly discovered organism is _____ compared to the surrounding water. hypotonic isotonic hypertonic
The newly discovered organism is hypotonic compared to the surrounding water. Thus, the correct option for this question is A.
What will happen if aquatic organisms have kidneys?The function of the kidneys in aquatic organisms is to excrete excess water by retaining most of the filtered solutes. This makes the aquatic organisms more survival because the retaining of solutes gives more energy.
If the newly discovered organism is hypotonic to the surrounding water, it takes the water from the surrounding atmosphere which is then excreted by the kidney through the retention of filtered solutes. This mechanism is accomplished by simple diffusion. While gills are not present in the newly formed organism.
Therefore, the newly discovered organism is hypotonic compared to the surrounding water. Thus, the correct option for this question is A.

Which is the neurotransmitter that causes the release of calcium ions from reservoirs within the muscle cell and thereby initiates the steps of contraction?
Answer:
Explanation:
Motor neurons release acetylcholine from synaptic vesicles to trigger muscle contraction. Motor neurons contain high concentration of synaptic vesicles filled with acetylcholine which is the neurotransmitter that triggers contraction of skeletal muscle cells.
On a hike through the forest, you notice a population of 100 flowering plants that all look identical. They span an area of approximately 100 square meters, but there are other populations of this species nearby. You take some representatives from one corner of their distribution back to the lab, sequence their DNA and conclude that they are genetic clones. True or false
Answer:
True
Explanation:
They are identical genetic clones so there is no difference which is the key to natural selection, hence given statement is false.
What is natural selection?Since they are genetic clones and hence identical, they lack the phenotypic variation that is essential for evolution to take place through natural selection.
Genetic drift cannot happen since they have the same phenotype and are genetically similar.
Genetic variation must occur randomly for genetic drift to take place there must be a shift in the frequency of one allele over time within a population for genetic drift to take place.
Therefore due to an identical clone, there is no chance of natural selection, hence given statement is false.

compared to blood capillaries, lymphatic capillaries__________.
Compared to blood capillaries, lymphatic capillaries are larger in diameter and possess closed ends.
What is the function of lymphatic capillaries?The function of lymphatic capillaries deals with the process of keeping the overall balance of fluid in your body. This function is stimulated by returning the interstitial fluid back into the circulatory system with the help of lymph capillaries.
In blood capillaries, fluid can never being flowed but in lymph capillaries, fluid can easily flow throughout the cell walls. But the movement of this fluid is only permitted in the forwarding direction. This is also the unique feature of lymphatic capillaries.

1. Where are various rocks formed?
2. Difference between oceanic and continel rocks.
Answer:
Explanation:
pt.1 There are three major types of rocks: Metamorphic, Igneous, and Sedimentary. Metamorphic Rocks - Metamorphic rocks are formed by great heat and pressure. They are generally found inside the Earth's crust where there is enough heat and pressure to form the rocks. Metamorphic rocks are often made from other types of rock.
pt.2 The oceanic crust is made up of basalt while the continental crust is made up of granite. The oceanic crust is thinner while the continental crust is much thicker. The oceanic crust is denser than the continental crust. The continental crust has greater buoyancy than the oceanic crust.

A problem with secretion is the reason why Miguel's blood test shows an increase in metabolic waste.
A problem with secretion is why Janice's urine report shows the presence of vital minerals.
What is a nephron?A nephron is the functional unit of the kidneys that is responsible for the formation of urine.
Each nephron has a structure for blood filtration known as the glomerulus. The glomerulus is a network of capillaries that is surrounded by the Bowman’s capsule or the glomerular capsule which is a cup-like structure.
During filtration by the nephron, water and minerals are filtered out of the blood.
During secretion, small molecules such as waste minerals and hydrogen ions pass from the capillaries into the renal tubule and are removed as urine.
