<span>El Nino is the part of the ENSO cycle in which the surface temperature of the Southern Pacific ocean is warmer than usual. This causes increased rainfall in the Americas, but can reduce precipitation in Indonesia and Southern Asia. Hence the correct answer is A) rain; drought.</span>
AnswerExplanation:
The nucleolus is a region of the nucleus where ribosomal RNAs are synthesized.
Ribosomes are protein synthesis factories made from the ribosomal RNAs that are synthesized in the nucleolus and ribosomal proteins.
Sometimes, ribosomes are found free in the cytoplasm, other times they are attached to the endoplasmic reticulum, forming the rough endoplasmic reticulum. The rough endoplasmic reticulum is the site of protein synthesis for proteins that are to be secreted from the cell
Answer:
All plants and the plant products like vegetables and fruits are made up of turgid living cells. Turgor is the pressure buildup in the plant cell by the fluid, which causes the cell membrane and the cell contents exert an outward pressure against the cell wall. When this structure is destroyed, the cells break and produce a noise due to the sudden release of turgor pressure. That's why a fresh carrot or celery will produce a "snap" sound when we break it. A vegetable that is not fresh lose moisture and their cell's turgidity slowly. Upon losing the turgor they will become limp and wilts.
Explanation:
A plant cell has a rigid outer cell wall made up of cellulose, hemicellulose, pectin and lignin. The cell membrane inside the cell wall is semi permeable which allows only certain components to move freely through this membrane. Water can pass in or out of a cell through the cell wall and the cell membrane by osmosis and transpiration. Another structure inside the plant cell called vacuole acts as a bag of water and creates turgor in the cell.
Turgor pressure or turgor is the pressure buildup in the plant cell by the fluid, which causes the cell membrane and cell contents to exert an outward pressure against the cell wall. The cell wall is made to withstand this pressure. When the vacuole filled with water presses against the cell wall, it makes the cell wall nice and firm. Thus the turgor makes the vegetables like carrot and celery firm. So a fresh carrot or celery will produce a snap sound when we break it because their cells break and produce a noise due to the sudden release of turgor pressure inside the cell.
Once the vegetables are harvested or damaged, they transpire and lose moisture slowly. As a result, the vacuole which is not full of water anymore does not press against the cell wall and the cell loses its turgidity. Upon losing the turgor the plant will become limp and wilts. That's why a vegetable that is not fresh will not make the snap sound when we break it and may bend.
In order for a fruit or vegetable to remain crunchy and crispy, it is important to maintain the turgor inside their cell. To maintain the turgor, the vegetables should not be damaged so that the cell wall does not break and should stay in place. Also there should be enough water inside the cell, so avoid placing them in direct sunlight.

Answer:
Multicellular
Explanation:
Unicellular, as the prefix "uni" implies, only have ONE cell. Unicellular organisms can include bacteria, yeast, protists, etc. Multicellular organisms have many cells and are any plant or animal, as they are much larger and complex than unicellular organisms.
As for the second question, the frilled lizard is a perfect example of the ways that organs work together to form necessary organ systems. In the instance of the heart, there are cardiac muscle cells that branch and connect to each other to form cardiac muscle tissue, which has special junctions that cause the cells to contract together and in turn keep the heart pumping and the circulatory system moving.
Does this make sense? Feel free to comment any other questions!! If this explanation helped you, please consider leaving me a good review and/or brainliest!! <3
