Answer:
Crossing over
Explanation:
for variations which is one of the most important characteristic for Meosis
Compaction and cementation into sedimentary rock, then heat and pressure into metamorphic rock. this is correct answer
Answer;
-the continental shelf, slope, and trenches;
The continental shelf, slope, and trenches are the structures on the ocean that are equivalent to the mountains on land.
Explanation;
-Continental shelf is that shallow part of the ocean floor that begins at the shoreline and gently slopes underwater to an average depth of about 430 feet. It is normally covered with thick layers of sediment.
-Continental slope begins at the edge of the continental shelf and plunges down to depths of over two miles and are covered with thick layers of sand, mud and continental shelf.
-Ocean trenches are very deep and similar to canyons on land.

(this is talking about the periodic table
Answer:
it's really simple, all you need to do is look at the periodic table. for example, group 1A has 1 valence electron. 2A has 2, 3A has 3, and so on.
Without enzymes, the body couldn't perform essential chemical reactions quickly enough to sustain life. Enzymes also aid digestion and help in immune defence. Their absence would critically interrupt bodily functions and overall health.
If there were no enzymes in the human body, many essential biological processes would be negatively impacted. Enzymes act as biological catalysts, speeding up the chemical reactions that occur within cells, thereby allowing life-sustaining processes to occur at the rate necessary for life. If we didn't have enzymes, these reactions would happen too slowly to sustain life, or might not happen at all.
Enzymes are vital in breaking down food and converting it into usable energy. Without enzymes, our digestive system would not be able to efficiently break down nutrients, leading to malnutrition and energy deficiency. Moreover, enzymes are involved in the immune system's defence mechanisms. They assist in the destruction of foreign pathogens, thus protecting the body from infections.
Furthermore, each cell's enzyme demand changes according to its needs and role within the body. For instance, the enzymes necessary in stomach cells differ from those in skin, blood, or nerve cells reflecting the diverse functions enzymes perform in the human body.
Overall, without enzymes, the human body would be unable to function properly. They are essential for our survival, and their absence would dramatically alter the way our bodily systems operate.
