A few of these characteristics are favourable and are called as beneficial mutations which provide a better survival benefit to changing surroundings. Evolution of a new class of species altogether occurs when a permanent change takes place in the phenotype of an entity as a result of natural selection and competition when an environment continues to stay for longer durations incorporating better-adapted entities.
Gene mutations cause the evolution we observe. It causes a change either in the organization or amount of genetic material in a cell. Such a mutation if occurred in a gamete can be easily inherited by the emerging gamete. New alleles of genes are produced as a result of mutations and hence the variations between entities. Therefore, genes and genetic mutations play a significant role in the process of evolution.

Before you can calculate the estimated population size from a population sampling study, which of these is the MOST important data point to find?
Answer:
D
Explanation:
The average number of tagged individuals caught over all trials is the MOST important data point to find
Average no. of tagged individual caught over all trial.
The size of the sample is always less than the total size of the populationWhy is population size calculated?Knowing the size of a population of animals is important in making environmental decisions that would affect the population, but estimating the size of wild populations is extremely difficult.
What are the factors affecting population size?Amount of food.Amount of shelter.Amount of access of medication and medical care.Birth rate increase or decrease.Death rate increase or decrease.Amount of water.Hence, D option is correct.

Explain how organisisms as diffrent as diatoms and ciliates belong to the same kingdom protest group.
Answer:
Ciliates belong to the eukaryote supergroup Alveolata (alveolates). These protists are characterized by the presence of unit membrane-bound sacs or alveoli, underlying their plasma membrane (Figure 1). There are three major groups within alveolates – the dinoflagellates, the apicomplexans, and the ciliates.

Homo erectus was likely the first hominid to successfully migrate to regions beyond Africa. Discuss how the biology and culture of Homo erectus led to its success on three major continents with varying environments.
Being the first designer of hand axes, stone fire, and other tools, Homo erectus was successfully established in other continents with varying environments.
What do you mean by Environment?The Environment may be defined as anything which is present in the surroundings of living organisms.
While making such tools for their use, they need proteins to survive and play their functional role. It leads to the mutation in their protein structure and behavior.
They used fire for cooking, heating their body during winter, and threatening away large predators.
Due to all these inventions, they successfully adapted to three major continents with varying environments.
Therefore, it is well described above.

Explanation:
Gas Exchange and Transport Oxygen and carbon dioxide are exchanged across the walls of alveoli and capillaries. Chemical properties of blood and red blood cells allow for efficient transport of gases throughout the body.Carbon dioxide and oxygen are exchanged across capillary and alveolus walls.Hemoglobin binds with and transports oxygen that diffuses from alveoli to capillaries. It also increases the efficiency of gas exchange.Carbon dioxide is transported in the blood in three ways. Most combines with water and forms carbonic acid. Some dissolves in plasma. Some binds to hemoglobin and proteins in plasma.
For Questions 2-7, complete each statement by writing the correct word or words.
6. ___________ binds with oxygen and increases the blood's oxygen-carrying capacity.
Answer:
Hemoglobin is a protein found in red blood cells that is comprised of two alpha and two beta subunits that surround an iron-containing heme group. Oxygen readily binds this heme group. The ability of oxygen to bind increases as more oxygen molecules are bound to heme.
