What is population density?</h3>
The density of individuals within a species in a given geographic location is referred to as population density. Data on population density can be used to calculate demographics and examine interactions with ecosystems, human health, and infrastructure.
The population density equation below can be used to calculate the population density of a piece of land:
Population Density = Population/ Area
The residential density is important in determining the people's thinking and culture. Engineers find it vital to forecast population growth in order to develop infrastructure that can support a large population. It is practically impossible to develop a perfect 3D model of any structure that allows the largest number of people to live without this understanding.

Answer:
The female (XcX) is carrier for color blindness while the male (XY) is normal. The carrier female transmits its one X chromosome with gene for color blindness to one of her sons making him color blind.
Explanation:
Color blindness is X linked recessive disorder and followed the criss-cross inheritance wherein the color blind sons get the gene from their carrier/affected mother while the color blind father would transmit the gene to his daughters along with X chromosome.
Since both the parents are normal, the mother (XcX) should be carrier for the disease to get the color blind son. A cross between carrier mother (XcX) and normal father (XY) would make 50% of their sons color blind.
Answer:
Option A, Jean-Baptiste Lamarck
Explanation:
Options
a. Jean-Baptiste Lamarck
b. Georges Cuvier
c. Thomas Malthus
d. Charles Darwin
e. Charles Lyell
Solution
The second law of Lamarck stated that all living organism eventually adapt to the environment in which they live. However, such adaptations are continuous thereby leading to evolution of species gradually over a long period of time. Lamarck published his theory of evolution in 1801, while Darwin published his book on “origin of species in 1859.
The result predicted by Lamarck regarding impact of environment on evolution was further supported by Darwin, and future scientist.
Hence, option A is correct
