B.
Land absorbs the sun's energy slowly, while oceans absorb it more quickly.
C.
Land only absorbs radiation that is not harmful to humans.
D.
Land reflects more of the sun's energy, while oceans absorb it slowly and retain it longer.
The statement that describes the major differences as to how the oceans and the land absorbs the energy from the sun is that Land reflects the Sun's energy quickly, while oceans absorb it more slowly.
Earth's oceans are far more important than the land as a source of the heat energy which drives weather and climate. As they also absorb more sunlight and store more heat.
The sun warms up parts of the oceans. Warm waters rise just like warm air rises. So, as the warmer ocean waters begin to rise in a particular area, the cooler ocean waters from a different area will move in to replace the warmer ocean waters, and this creates our ocean currents.

which substance is a main product of cellular respiration that is made by the krebs cycle
• ethanol
• carbon dioxide
• water
• pyruvate ions
Answer:
carbon dioxide is a main product of cellular respiration that is made by the Krebs cycle
The main product of cellular respiration that is made by the Krebs cycle is carbon dioxide.
The Krebs cycle, also known as the citric acid cycle or tricarboxylic acid cycle, is a central metabolic pathway in cellular respiration. It occurs in the mitochondria of eukaryotic cells and plays a critical role in extracting energy from glucose and other fuel molecules.
During the Krebs cycle, a series of chemical reactions occur, resulting in the conversion of acetyl-CoA, a two-carbon molecule, into several intermediate compounds. One of the key steps in the Krebs cycle is the decarboxylation reactions, where carbon dioxide (CO₂) is released as a byproduct.
In each turn of the Krebs cycle, carbon dioxide is produced from the breakdown of carbon atoms within the acetyl-CoA molecule. This release of carbon dioxide occurs twice for every glucose molecule that enters the Krebs cycle since two acetyl-CoA molecules are generated from the initial glucose molecule through prior steps of cellular respiration.
The carbon dioxide generated during the Krebs cycle is then transported to the lungs through the bloodstream, where it is eventually exhaled. This is an essential part of the respiratory system's role in eliminating waste products from cellular metabolism.
Therefore, the main product of cellular respiration made by the Krebs cycle is carbon dioxide. It is a byproduct of the oxidation of fuel molecules and is crucial for maintaining the balance of gases in the body and facilitating efficient energy production.

A geometric transformation that maintains a figure's size and shape is called an isometry, also referred to as a hard transformation.Under an isometry, points remain on a line, parallel lines remain parallel, angle measurements, parallelism, and collinearity all remain true. A geometric transformation that maintains a figure's size and shape is called an isometry, also referred to as a hard transformation.Under an isometry, points remain on a line, parallel lines remain parallel, angle measurements, parallelism, and collinearity all remain true. A dilation will always result in comparable numbers.A figure's orientation will always alter as a result of dilatation. Another name for a congruence transformation is an isometry.Thus, it keeps both side lengths and angle measurements.Only dilation among the alternatives alters the side lengths, hence it is not an isometry.So, option A is the proper response. Similarity transformations include translation, reflection, rotation, and dilation.Rotation, reflection, and translation preserve both size and shape because they are rigid motions, whereas dilation just makes sure that the shape is preserved. They could be twisted or flipped, so they could not have the same orientation, but they do have the same measurements.Congruent shapes are the result of most transformations.The image resembles the pre-image after one change.Similar implies that they have the same proportions and shape but differ in size. Translations, reflections, and rotations are examples of congruence transformations because the image of a figure after one of them is congruent with its preimage.When the image and preimage are congruent, a transformation is said to be a congruence transformation. An object can become another object by rotation.We can see that spinning an object does not alter its size or shape.Rotational transformations are hence isometric transformations.So a rotation is also an isometry. A stiff motion from some space that preserves distance is called an isometry.For instance, the real line isometry f(x)=x+5 shifts the entire line by 5 while maintaining the point-to-point distances.An isometry of a space that maps a figure to itself is called an object's symmetry in that space. a metric space is mapped onto another or onto itself in such a way that rotation and translation are isometries of the plane, meaning that the distance between any two points in the original space is equal to the distance between their images in the second space.A shape-preserving transformation (movement) in the plane or in space is called an isometric transformation (or isometry).The isometric transformations include translation, rotation, and combinations thereof, such as the glide, which combines a translation with a reflection.To learn more about trasformations refer

A dormant protective structure that can form in adverse or normal conditions is called?
A dormant protective structure in bacteria that can form in adverse or normal conditions is called an endospore.
Endospore is a condition in which resistant spore forms inside some bacteria and serves as a shield against harmful conditions. Endospore-forming bacteria are called gram-positive bacteria and can survive under harsh conditions.
In their survival mechanism, gram-positive bacteria divide within the cell and produce intracellular spores which are resistant to harsh conditions. On the other hand, instead of showing development bacteria decide to stay dormant for a while and even longer if the conditions are unfavorable such as low temperature.
However, if the conditions become favorable they resume their growth again.
The conditions that endospores can survive include environmental stress and heat, high temperature, and chemical damage.

how does the carrying capacity and limiting factors effect on reproductive patterns
Carrying Capacity
Carrying capacity is the number of organisms an ecosystem can support. If the population grows past the carrying capacity, then the environment or organisms will begin to suffer. The carrying capacity of an ecosystem is dependent upon the available resources and the needs of the organisms. Some ecosystems have more available water than others; these areas will have higher carrying capacities.
Limiting Factors
Limiting factors are things that restrict the population of an organism. For example, space, water, and food are all limiting factors. Within one ecosystem there is a finite amount of all resources. These limited resources restrict the number of organisms that can survive in one area.
Reproductive Patterns
Carrying capacity and limiting factors can affect reproductive patterns in different ways. If a population is reaching carrying capacity, then population growth could decrease as organisms do not have enough resources to reproduce. Additionally, some ecosystems have wet vs. dry seasons. In these areas, water, a limiting factor, is more available at specific times of the year. So, organisms might be more likely to reproduce as there is more access to limited resources.
