<u>Answer:</u>
Blastocyst is a structure that subsequently forms the embryo during the process of fertilization.
<u>Explanation:</u>
- In the "innermost layer of the uterine wall" there is endometrium layer, this is where the uterus does the embryo implant.
- The blastocyst stage is the period of embedding the "lining of the uterus".
- But the fertilization of egg is done in the "Fallopian tube" and is later implanted in the uterus.
- Hence blastocyst is the lining structure of the uterus as the implantation of embryo occurs.
Answer:
Metaphase ⇒ Chromosomes line up in the middle of the cell
Prophase ⇒ DNA condenses to form chromosomes
Anaphase ⇒ Each chromosome separates and moves to opposite ends of the cell
Telophase ⇒ Nuclear membranes form around each set of chromosomes
Plates at our planet's surface move because of the intense heat in the Earth's core that causes molten rock in the mantle layer to move. It moves in a pattern called a convection cell that forms when warm material rises, cools, and eventually sink down. As the cooled material sinks down, it is warmed and rises again.
Remember that CO2, light and heat (to activate the reaction and keep the enzymes happy) are all needed for a reaction. When one goes missing, it destroys the whole process.
1. No light = no reaction can be made. That means the plant wouldn't intake any CO2 anyway.
2. When very hot the enzymes will denature (plant dead) or when cold, the activation energy will not be there. So once again, it will not respond to light as it is not its primary concern.
Answer:
The principal reason for the increase of groundwater use is the increasing population. Urbanization and pollution have both contributed to an increase in the use of groundwater. Polluted rivers, lakes, and springs are no longer viable sources of groundwater.
