Because water keeps you hydrated and that's cool, but alcohol makes you drunk and that's not cool.
Answer:
Speciation, it's the formation of a new organism in evolution
Answer:
Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population.
Answer:
22 cells
Explanation:
The concentration of numbers of cells = 6.74 x 10⁶ cells/ml
Dilution stages includes = 1:100 ; 1:100 & 1:3
The consecutive dilution stages can be calculated as:
= (6.74 x 10⁶) × (1/100)(1/100)(1/3)
= 222.42 cells/ml
= 2.22 × 10² cells/ml
So after addition 0.1 ml of the final dilution to a spread plate, the number of CFUs ( Colony forming units) we expect to count will be:
= (2.22 × 10² cells/ml)(0.1 ml)
= 22.2 cells
≅ 22 cells.
Answer:
Bilateral symmetry allows for directional motion. The coelom cushions organs allow freedom of motion.
Explanation:
Most animals are bilaterally symmetrical in nature with a line of symmetry dividing their body into two sides left and right sides along-with a “head” in top and “tail” in the bottom. Bilateral symmetry consisting an equal arrangement of symmetry about a vertical plane running from top to bottom.
The coelom is known as the main body cavity present in most animals. It is positioned inside the body to surrounds the digestive tract and other organs. In some animals, it is lined with mesothelium. In other animals, such as mollusks, it is undifferentiated. In animals, it helps to allow freedom of motion.
