d. sampling unit
Explanation:
<u>Sampling unit:</u>
Refers to the unit or group of elements that are selected from an original population during an investigation. The sampling unit might be composed of a statistical unit or a group of statistical units.
The statistical unit or element is the elemental unit that composes the target population.
The sampling unit is a basic concept to keep present during the development of the investigation project. It is the minimal unit of observation that will be used to take information about the variables of interest. All the sample unit composes the population and is defined by an <em>N</em>, while only some representative sample units compose the sample, and are represented with an <em>n</em>.
So, the whole population can not be measured because of its size, or the individuals´ characteristics, among other many factors. So we need to take a random and representative sample or group of the population to proceed with our investigation. This sample or group is composed of some of the original population individuals, which are defined as "sample units".
The type of fertilization that one would expect to find in this specie is EXTERNAL FERTILIZATION. External fertilization is the type of fertilization in which the male sperm fertilize the female eggs out of the female's body. This type of fertilization usually occur in aquatic environment.

It is the origin of the attachment of many muscles as well as ligament.
The femur is the longest bone which is present in our thigh and also call as thigh bone. The division of femur can be divided into shaft, proximal and distal. In some aspect it is the strongest bone of our body and it helps in any activities.
Charles Darwin's evolutionary theory enables us to establish cause and effect in biology, including those associated with a person's overall character. The evolutionary biologist Theodosius Dobzhansky wrote: "Nothing in Biology Makes Sense Except in the Light of Evolution". It's a well-known statement on the evolutionary theory and their implications in all spheres of biology
There are many environmental negative direct outcomes of unused excess nitrogen from nitrogenous fertilizers. One of these is eutrophication. Eutrophication is the excessive richness of nutrients in a water body as a result of fertilizer run offs from the land, which causes a dense growth of plants in the water. Other negative outcomes are: green house effects, acid rain and contamination of underground water which has negative effects on human health.
