Answer:
If Earth’s axis was tilted like that of Uranus, the days and the seasons would be very different. On Earth only the poles have perpetual darkness during winter and perpetual daylight during summer. With an axial tilt like Uranus, the Equator and the Arctic / Antarctic circles are almost at the same latitude. With the axis of Earth tilted 90 degrees, the Sun would stay almost directly overhead for months at a time at the polar regions, there would be hardly any change between a day and a night. Basically you have a time period lasting months which is equivalent to the midday of current equatorial regions.

which best represents an example of carbon fixation?
The option that best represents an example of carbon fixation would be the incorporation of CO2 into organic molecules.
Carbon fixation refers to the process of converting atmospheric carbon, mostly in the form of carbon dioxide, to organic molecules in the form of carbohydrates, usually in living organisms.
In living organisms carbon is fixed either via photosynthesis or chemosynthesis.
During the photosynthetic process, inorganic carbon in the form of carbon dioxide combines with water and is converted into carbohydrates in the presence of radiant energy. The process usually happens in green plants.
During chemosynthesis, carbon dioxide reacts with H2S instead of water to arrive at carbohydrates. The process usually happens in chemosynthetic bacteria.
More on carbon fixation can be found here: https://brainly.com/question/7142342
The process of photosynthesis is the best example of carbon fixation.
In the process of photosynthesis, energy from sunlight drives the carbon fixation pathway. photosynthesis process is used by the primary producers such as plants, algae, and cyanobacteria. They contain green pigment named chlorophyll that used the Calvin cycle to fix carbon.
The carbon atom present in the atmosphere in the form of carbondioxide gas fixes by the producers in the form of glucose which have 6 carbon atoms so we can conclude that photosynthesis is the best example of carbon fixation.

which statement is not connect for a convex mirror? (a) Image distance is always positive. (b) The object distance is with negative sign. (c) behind the memor -Always forms an imagebehind the mirror (d)The focal length is always negative.
Answer:
option (d) is incorrect
Explanation:
the focal lenth in convex mirror [mirror has an outer bulge], is positive, because in this type of mirror image is formed behind the mirror on right side .
according to sign convention, length on the right side it is positive.

Which of the following would increase the rate of an enzyme-catalyzed reaction?
Decreasing enzyme, decreasing substrate, decreasing cofactors
Decreasing enzyme, decreasing inhibitors, decreasing cofactors
Increasing enzyme, decreasing substrate, decreasing cofactors
Increasing enzyme, decreasing inhibitors, increasing cofactors
Answer: Increasing enzyme, decreasing inhibitors, increasing cofactors
Explanation:
Why? Well, we know that increasing how much enzyme is available is a good method to speed up the rate of an enzyme catalyzed reaction because we have MORE enzymes to deal with the substrates. We also know that cofactors are essential for widening the range of substrates an enzyme can catalyze. Cofactors also stabilize charge, so the substrate can fit into the binding site better.
