It is scientifically approved that algae and fungi are able to form true asexual spores. This process of spore formation involves mitosis and resultant spore is called mito-spore which develop into new offspring.

A pharmacist has two vitamin-supplement powders. The first powder is 10% vitamin B1 and 30% vitamin B2. The second is 15% vitami
Basile [38]

Answer:

560 mg of powder 1 and 160 mg of powder 2

Explanation:

Let "X" denotes weight of powder 1 added to the new mixture and  "Y" denotes weight of powder 2 added to the new mixture

Total weight of vitamin B1 in the mixture is equal to 80 mg

Total weight of vitamin B2 in the mixture is equal to 200 mg

Equation 1

0.1 X + 0.15 Y= 80

Equation 2

0.3 X + 0.2 Y= 200

Let us simplify the above two equations, we will get

10 X + 15 Y = 8000\\3X + 2Y = 2000

2 (10 X + 15 Y = 8000), 20X + 30 Y = 1600015(3X + 2Y = 2000), 45X +30Y = 30000\\25 X = 14000\\X = 560

Substituting value of X in equation 2 we get

0.3 * 560 + 0.2 Y = 200\\0.2 Y = 200 - 168\\Y = 160

If the adhesive forces between a liquid and the walls of a capillary tube are greater than the cohesive forces within the liquid
olga_2 [115]

Answer:

Option A, the liquid level in a capillary tube will drop below the surrounding liquid and the surface in the capillary tube will have a convex meniscus.

Explanation:

A liquid will wet the surface of the container in which it is contained only when the adhesive forces between the molecules of the liquid are weaker than the adhesive force between the surface wall of the container and water.

A  convex meniscus is formed when the attractive forces between the molecules of liquid (cohesion) becomes greater than attractive forced between the water molecule and the container's surface (adhesion)

Convex meniscus simultaneously move the surface of the liquid in the downward direction due to which its level become lower than the surrounding layer.

Hence, option A is correct
