Answer:
To cause a phase change, you either add heat energy to a substance to cause it to evaporate, melt, or sublimate, or you subtract heat energy, or take it away, to make the substance freeze or condense. Hope it helps!
Explanation:
Xylem, which is a dead cell that carries water in only one direction: up
Unicellular organisms include bacteria, protists, and yeast. For example, a paramecium is a slipper-shaped, unicellular organism found in pond water. It takes in food from the water and digests it in organelles known as food vacuoles. Nutrients from the food travel through the cytoplasm to the surrounding organelles, helping to keep the cell, and thus the organism, functioning. Multicellular organisms are composed of more than one cell, with groups of cells differentiating to take on specialized functions. In humans, cells differentiate early in development to become nerve cells, skin cells, muscle cells, blood cells, and other types of cells. One can easily observe the differences in these cells under a microscope. Their structure is related to their function, meaning each type of cell takes on a particular form in order to best serve its purpose. Nerve cells have appendages called dendrites and axons that connect with other nerve cells to move muscles, send signals to glands, or register sensory stimuli. Outer skin cells form flattened stacks that protect the body from the environment. Muscle cells are slender fibers that bundle together for muscle contraction. The cells of <u>multicellular</u> organisms may also look different according to the organelles needed inside of the cell. For example, muscle cells have more mitochondria than most other cells so that they can readily produce energy for movement; cells of the pancreas need to produce many proteins and have more <u>ribosomes</u> and rough <u>endoplasmic</u> <u>reticula</u> to meet this demand. Although all cells have organelles in common, the number and types of organelles present reveal how the cell functions.

The correct option is (A) in biomes at different latitudes.
When climbing a mountain, we can observe transitions in biological communities that are analogous to the changes in biomes at different latitudes.
<h3>
What is biome?</h3>
- A naturally existing species community that is influenced by a region's climate and latitude is referred to as a "biome."
- A place where two biological communities come together and merge is known as an ecotone. It could be small or large, local (the area between a field and a forest), or regional (the transition between forest and grassland ecosystems).
- As you ascend a mountain, different sections experience varying amounts of sunlight and warmth. People see differences in the biological community as an organism ascends a mountain because different latitudes are present.
