Answer:
Implantation is the mechanism by which a blastocyst, which is passing through the uterus as a developing embryo, makes contact with the uterine wall and remains bound to it before birth. The uterine lining (endometrium) undergoes several internal modifications in order to allow for the emerging blastocyst to bind to it.
Explanation:

Magnitude and direction
Explanation:
A vector quantity has both magnitude and direction. This is different from a scalar quantity that has only magnitude but no direction.
- Examples of vectors are velocity, acceleration, displacement, momentum e.t.c
- These quantities are physical quantities in which their magnitude has specific directions through which they are channeled.

The biceps and triceps muscles work together to allow you to bend and straighten your elbow. When you want to bend your elbow, your biceps muscle contracts (Figure below), and, at the same time, the triceps muscle relaxes. The biceps is the flexor, and the triceps is the extensor of your elbow joint.
Answer:
Weight: newtons, kilograms and changes when gravity changes
Mass: does not change when gravity changes, the amount of matter in something, and a gravitational force
Hope I get this right :)
Answer:
It is also referred to as the phospholipid bilayer or the plasma membrane, It helps cells maintain homeostasis, It is selectively permeable; that is allows some substances through but not others
Explanation:
a. I don't know how to explain other names for the cell membrane but they are it, as the cell membrane is a bilayer composed of phopholipids and it is also called a plasma membrane
b. The cell membrane has many structures on it that facilitate nutrient transport in and out of the cell (ex: protein pump). nutrients of higher concentrations would like to move through lower concentrations, and it achieves this by moving across the cell membrane in or out of the cell, maintaining homeostasis
c. Some substances such as NaOH use pumps on the cell to move in or out of it, it can't get in or out without using pumps since they are so big, so the cell can choose when the cell wants it's nutrients or if it dosen't
