Answer:

The correct answer would be "Through a receptor on the cell membrane that transduces its signal to the cell's DNA".

Hormones produce their effects mainly by binding to their specific receptors. It leads to the formation of a hormone-receptor complex which results in certain biochemical changes on a target tissue.

These receptors can be of two types of membrane-bound and intracellular receptors.

The hormones which are protein or amine in nature are water soluble and thus can not pass through the lipid bilayer of a cell. They produce their effects mainly by binding to the membrane bound receptors. For example, insulin, growth hormone, Adrenaline, ADH, oxytocin, FSH, TSH et cetera.

Insulin binds to glycoprotein complex receptor present in the cell membrane.

In contrast, a lipid-soluble hormone such as steroidal hormone (estrogen) binds to the intra-cellular receptors as they can easily pass through the lipid bilayer.

Answer: False

Explanation:

Pathogens can be transmitted in many ways. It can spread by direct contact, indirect contact, or by vectors.

The mode of transmission can be skin contact, airborne particles, touching a surface, bodily fluids, touched by an infected person.

The mode of transmission can be vector that carries disease and helps in disease transmission.

So, the pathogens can be transmitted by direct contact, indirect contact or by vectors and by many more ways.

If a cell culture has 3 x 105 cells per ml , and the culture flasks hold 75 ml of culture each and you have 12 flasks, how many
natta225 [31]

There are 27 x 10⁷ cells in total for the given conditions of cell culture.

Since it is given that the cell culture contains 3 x 10⁵ cells per ml and there are 12 culture flasks in total. It is also given that each of the culture flask holds 75 ml of culture.

Therefore, to calculate the total capacity of the flasks the total number of flasks should be multiplied with the individual capacity of a flask:-

75 x 12 = 900 ml

Now, in order to calculate the total number of cells in the given culture., the total capacity of the flasks i.e. 900 ml should be multiplied with 3 x 10⁵ cells per ml in the following manner:-

900 x (3 x 10⁵) = 2700 x 10⁵ = 27 x 10⁷ cells
