Brainstorm various types of taxis that can be observed in animals. Describe two that have not been previously mentioned and indicate if they are positive or negative.
Taxes are the animals' movements orientated to stimuli or away from them. Phototaxis, chemotaxis, hydrotaxis, geotaxis, thigmotaxis, phonotaxis, etcetera.
What are taxes?
Taxes are the movements or changes in orientation done by organisms in response to a stimulus. It is about getting closer or farther from the stimuli. According to this, we can differentiate the followings,
Positive taxes ⇒ when the organisms react and move toward the stimuliNegative taxes ⇒ when the organisms react and move away from the stimuli
The stimulus is received by receptors in the organism's body. The type of response will depend on the type of stimulus.
Different types of taxes depend on the type of stimuli and the organism that receives them. Taxes might vary among plants and animals.
Taxe observed in animals are,
Anemotaxis ⇒ displacement according to the wind's direction. Some insects show these taxis. Phototaxis ⇒ organisms respond to light in different ways. For instance, some worms and cockroaches move away from light, while moths and flies are attracted to light. Phonotaxis ⇒ Orientation according to sounds. Geotaxis ⇒ motion according to gravitational movements. For instance, jellyfishes move to the bottom of the sea (positive geotaxis) or the surface (negative geotaxis). Hydrotaxis ⇒ Movement to or away from water. When marine turtles are born, they move toward the ocean.Reotaxis ⇒ Moving with or against the water current. Thermotaxis ⇒ Movements of the organism according to the source of the hit. Mosquitos for example express positive thermotaxis. Cockroach moves toward warm sources. Thigmotaxis ⇒ Responses to vibrations or pressures. For instance, spiders show positive thigmotaxis when they identify the vibrations of a trapped insect in their webs.Chemotaxis ⇒ Response of animals to chemical signals. For instance, ants show positive chemotaxis while looking for food. Sharks express positive chemotaxis when they smell blood. Moths show positive chemotaxis when they receive pheromones.Galvanotaxis ⇒ Motion according to electrical stimuli.Astrotaxis ⇒ Movements following the stars, the sun, or the moon.
Having made these descriptions, you can mention all of them and describe the followings,
→ Phototaxis, explaining that
moths are attracted to light expressing positive phototaxis. cockroaches hide from lighted places, expressing negative phototaxis.→ Geotaxis, explaining that
jellyfishes express positive geotaxis when moving to the bottom.squids express negative geotaxis when moving to the surface.You can learn more about types of taxis at

Many dietary supplements contain digestive enzymes the manufacturers claim are necessary to digest food properly. What will happen to these enzymes in the stomach? (Hint: Enzymes are proteins.) Will the enzymes continue to function once they have reached the small intestine? Why or why not?
The enzymes which are found in food supplements will be denatured in the stomach and lose their activity.
What are digestive enzymes?Digestive enzymes are enzymes which aid in the process of digestion in the body.
The body produces the digestive enzymes required for the digestion of food.
Due to the acidic nature of the stomach, digestive enzymes in the stomach are synthesized as proenzymes to prevent denaturation.
Therefore, the enzymes which are found in food supplements will be denatured in the stomach and lose their activity.

Julia made the following table to compare prokaryotic and eukaryotic cells. Structure Prokaryotic cell Eukaryotic cells Cell wall is present Yes Sometimes Flagellum for movement Yes No X is present Yes Yes Which of the following would best replace X? Cell membrane Mitochondria Nucleus Vacuole
Mitochondria ,Prokaryotes lack mitochondria and instead have their ATP on their cell surface membrane. The eukaryotic cells are typically larger than prokaryotes and more various in their shape and structure.
Is mitochondria absent in prokaryotic cells?Prokaryotic cells are less structured than eukaryotic cells. They have no nucleus whereas their genetic content is free-floating within the cell. They also lack the numerous membrane-bound organelles found in eukaryotic cells. Thus, prokaryotes have no mitochondria.
Thus, option "B" is correct, Prokaryotes lack mitochondria and instead have their ATP on their cell surface membrane.

In 3-5 sentences, explain the difference in good and bad atmospheric ozone and how each is distributed in Earth's atmosphere.
(Giving 39 points and don't mind if this is in the wrong subject because this is Earth Science. And will give Brainliest!)
Answer:
Stratospheric ozone is considered “good” ozone because of this beneficial role. In contrast, ozone formed at Earth's surface in excess of natural amounts is considered “bad” ozone because it is harmful to humans, plants, and animals.Most ozone resides in the stratospheric ozone layer and a small percentage (about 10%) is distributed throughout the troposphere.
Between 15 and 30 kilometers above the surface of the earth, the ozone layer protects ourselves and other living things from the sun's harmful UV radiation.
What is ozone layer?The ecosystem and human health could be seriously impacted by the ozone layer's thinning. Over the entire globe, stratospheric ozone is being depleted.
However, the Arctic region of the northern hemisphere (where this phenomenon is more mild) than the southern hemisphere (Antarctica).
The so-called ozone hole is generally thought to be a concentration level of 220 Dobson Units or less, which is regarded to show serious ozone depletion. Only in the southern hemisphere is this noticeable. The ozone hole's historical maximum size is seen here at 28.4 miles.
Therefore, Between 15 and 30 kilometers above the surface of the earth, the ozone layer protects ourselves and other living things from the sun's harmful UV radiation.
