B. its false it's the other way around gametes are produced by gametangia :)
Answer:A. the same number of chromosomes as was contained in the zygote.
Explanation:a zygote is formed when the sperm fertilize the egg .
After fertilization,the zygote undergoes cleavage.cleavage is the mitotic Division of the cells of a zygote to produce daughter cells.
These daughter cells are called blastomere,which contains the same number of chromosomes as the parent cells.the cells formed do not grow in size but continues to divide, forming a mass of cells.
This mass may be solid at first but as cleavage continues,the cells move away from the center,leaving a fluid filled cavity in the middle (blastocoel).
The mass of cells are called blastula.
1. The Ring of Fire, also referred to as the Circum-Pacific Belt, is a path along the Pacific Ocean characterized by active volcanoes and frequent earthquakes. The majority of Earth's volcanoes and earthquakes take place along the Ring of Fire.
2. Crustal recycling is a tectonic process by which surface material from the lithosphere is recycled into the mantle by subduction erosion or delamination
3. Tectonic plate movement can create another supercontinent like Pangea if the plates move continents to the point of meeting together.
Answer:
Carbohydrates and lipids are similar in that they are both sources of energy but they are different in the amount of energy they produce.
Explanation:
Carbohydrate and lipids are similar in the sense that both of them are parts of foods consumed by humans and the two marcro molecules are good sources of energy for the body cells. The carbohydrate has to be broken down to glucose before it can be absorbed by the body cells. This is because glucose is the only energy source that the body cells can use. The lipid has to be converted to glucose through biochemical reactions such as gluconeogenesis before the cells can use it.
The basic difference between the two energy sources is that the amount of energy that they supply is quite different. Lipid contains more energy than carbohydrate; carbohydrate can only supply about one-quarter of the energy that lipid can supply.
Answer:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.
