Final velocity after 5 sec is 16 m/s
<u>Given that;</u>
Initial velocity = 4.5 m/s
Constant acceleration = 2.3 m/s²
Time taken = 5 second
<u>Find:</u>
Final velocity
<u>Computation:</u>
Using first equation of motion;
v = u + at
v = 4.5 + (2.3)(5)
v = 4.5 + 11.5
v = 16 m/s
Final velocity = 16 m/s

Answer;
Teratogens
Explanation;
-Toxic agents that can cross through the placenta and compromise an unborn child's development are known as Teratogens. They are usually in the environment that the mother may be exposed to during pregnancy.
-Teratogens may cause physical or functional birth defects in the child or may halt the pregnancy outright. The major classes of teratogens include radiation, maternal infections, chemicals, and drugs.
The correct answer is option (D) The active transport and the facilitated diffusion both involve the proteins present in the cell membrane.
Facilitated diffusion transport the large and the charged molecules through the protein transport channels present in the cell membrane. In this case, the solute move from a region of higher concentration to lower concentration and it does not require energy.
Active transports takes place when the molecules move from a region of lower concentration to higher concentration via the membrane protein channels.
Both facilitated diffusion and active transport requires the proteins present in the cell membrane.
Answer: While Biology is the study of living things, living things themselves are made up of chemical composition. That being said, our survival is dependent on the reactions taking place inside and outside the body. Hence, to understand living things, biologists needs a good understanding of chemistry.
