Answer:
Different combinations between these four set of chemicals
Explanation:
There can be billions of combinations between the four chemicals of DNA. The four set of chemicals i.e nucleotide (generally referred to as bases) namely -
A- Adenine
T- Thymine
C - Cytosine
G - Guanine
These nucleotide form codon i.e set of three nucleotide and form chain structure which can be long up to any extent.
Codon example - ATC TGA
Thus, variation in combination of four nucleotide and ability to form long chain of codon allows DNA to have several forms and variations
four distinct seasons, a temperature range from just below freezing to 70º F, almost 14 inches of rain in the winter months and more than 18 inches of rain in the summer
b.
warm temperature year round, very long dry winter and a very wet summer, a temperature range of 68° to 86° F, annual precipitation of 10 to 30 inches
c.
subarctic and cold climate, long, severe winters, average yearly rainfall is 15 to 20 inches
d.
extremely low humidity, less than 10 inches of rain per year, high temperatures during the day, frequently windy
Answer: The correct answer is D) Extremely low humidity, less than 10 inches of rain per year, high temperatures during the day, frequently windy .
Abiotic factors include the non living components of the environment.
For example- Temperature, humidity, and rainfall.
Desert biome is mainly considered as a part of drylands. It is characterised by extremely low humidity. Average rainfall in this biome is less than ten inches. This results in scarcity of water. It experiences extremely high temperature and is frequently windy.
Example of desert biome- Thar desert in Rajasthan.
Thus, option D) correctly describes the climate of desert biome.
A mutation changes the sequence of RNA bases in a gene.
B.
A mutation creates the sequence of RNA bases in a gene.
C.
A mutation changes the sequence of DNA bases in a gene.
D.
A mutation creates the sequence of traits in a gene.
b. two haploid gametes.
c. four haploid cells.
d. four haploid gametes.
After meiosis, there are four haploid cells which can develop into gametes. This process is crucial for sexual reproduction in eukaryotic organisms.
After meiosis, the correct answer is that there are four haploid cells. During this process, one diploid cell (which has two sets of chromosomes) undergoes two rounds of cell division to create four haploid cells (each with one set of chromosomes). These cells can then develop into gametes, or sex cells, which can join together during fertilization to form a new diploid organism. This is a fundamental aspect of sexual reproduction in eukaryotic organisms.

Answer: Cultural Evolutionism.
Cultural evolution is the theory that cultures change over time, similar to the evolution seen in biological organisms. It is based on the idea that cultures evolve and adapt to their environment and circumstances. An example is a transition from hunting-gathering society to an agricultural one based on the available land resources.
The view that cultures, like organisms, change over time is called cultural evolution. This theory posits that societal changes and developments happen gradually over time, analogously to the evolutionary changes seen in biological organisms. The concept of cultural evolution originates from 19th-century anthropology and was heavily influenced by Charles Darwin’s theory of natural selection. While there are debates and variations within this theory, at its base, it suggests that cultures evolve and adapt to their environment and circumstances, with these changes advantaging certain societies and helping them to succeed and prosper.
For instance, a culture that originally practiced hunting and gathering may evolve into an agricultural society when it encounters a fertile and productive land. This evolution of culture and society is not linear or inevitable, but dependent on a multitude of factors, including environmental, economic, and social conditions.
