Physical weathering because physical weathering refers to the geological process of rocks breaking apart without changing their chemical composition.
The answer is carbon dioxide, methane, and other gases; infrared. The greenhouse effect is the procedure by which radiation from a planet's environment warms the planet's surface to a temperature above what it would be without its air. Earth's regular greenhouse effect is basic to supporting life. Human exercises, primarily the consumption of non-renewable energy sources and clearing of backwoods, have fortified the nursery impact and caused a dangerous atmospheric division.
Everything in moderation, even healthy stuff. You need a balanced meal. Also, don't overload on avocados, too many will make you sick.
Answer:
The correct option is <em>B. Crossing- over </em>
Explanation:
In biology, crossing over can be described as a phenomenon by which homologous chromosomes exchange segments during the process of meiosis.
The unexpected results came because the DNA segment between the homologous chromosomes was exchanged during meiosis. The alleles got shuffled by this process and hence showed the unexpected results.
Crossing over and independent assortment are phenomenon which occurs only during the process of meiosis. These phenomenons cannot be observed during mitosis.
Answer:
The correct option is E) Contraction still occurs because Ca2+ can enter the cell directly through Ca2+ channels in the plasma membrane and bind to calmodulin.
Usually, the calcium ions are released from the sarcoplasmic reticulum of a cell during a muscle contraction, but if those are blocked, the contractions is an cell can still arise through the calcium ions which are present in the cell membrane of a cell.
