Considering the definition of probability, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%
Probability is the greater or lesser possibility of a certain event occurring.
In other words, probability establishes a relationship between the number of favorable events and the total number of possible events.
Then, the probability of any event A is defined as the quotient between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
In this case, you know that in a moth population, 48 are brown, 30 are yellow, and 67 are black. So, the total number of possible cases is calculated as:
total number of possible cases= 48 + 30 + 67= 145
The number of favorable cases for a moth to be brown is: 48
Then the probability that a moth is brown is calculated as:
= 0.33= 33%
On the other side, the number of favorable cases for a moth to be yellow is: 30
Then the probability that a moth is yellow is calculated as:
= 0.21= 21%
In summary, the correct answer is third option: the approximate probability of a moth being brown and yellow respectively is 33% and 21%

Answer:
The question is incomplete as the boxes of description is not given but the missing part is attached in the image-
Brain and spinal cord have a membranous covering made up of three layers, altogether known as meninges. These 3 layers are known as the Dura mater follows by the arachnoid mater and inner layer is the pia mater.
The description of the different layers are as follows-
1. Dura mater is the most superficial layer of the meninges. The superior sagittal sinus is present within this dura mater.
It creates tough inward folds that distinguished the cerebral hemispheres. Lines the inner side of the cranium in the skull.
2. Arachnoid mater is the middle layer present under the dura mater layer that surrounds the subarachnoid space. This layer is present Immediately deep to the subdural space.
3. Pia mater makes the deepest layer that follows the contours of the surface of the brain.

Answer:
B. The thick, waxy coating prevents water loss.
Explanation:
This is because the thick waxy coating needle refer to structure posses by plants or mostly xerophites plants to adapt to their environment. Plants that grow in area where there is no abundance of water for use normally posses these structures which will reduce evapotranspiration and conserve water. These plants normally have extensive roots to draw water.
