How does natural selection contribute to the theory of evolution?
Answer: Natural selection leads to evolution because the traits of those who are able to reproduce influence future generations genetics and gradually lead to these passed on traits becoming the normal state of being, thus causing the species in question to evolve.

A man who heavily smokes has developed lung cancer. The tobacco smoke has caused mutations in some of the cells in his lungs, making them unable to stop reproducing and dividing. He is worried that his children, none of whom smoke, may have inherited the lung cancer from him. Under what circumstances might his concern for his children be justified? If his smoking had already mutated the DNA in the cells in his lungs at the time his children were conceived, the mutations would have been passed to his children. If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children. If the mutation resulted from the duplication of a gene in his lung cells, his children would be at greater risk than if it were caused by a base pair substitution. If the smoke had caused multiple different mutations in his lung cells, it would be more likely that one or more of the mutations would be passed to his children.
Answer:
The correct answer is "If he inherited a mutation which made him more susceptible to lung cancer, it may have been present in some of the gametes he produced and passed to his children".

3. What are the inferences you can make from each of the activity above?
A reagent is a chemical substance that cause a chemical reaction or used to test the one. In the given activity, different reagents are used to predict the compound. Starch gives blue color on reaction with iodine, glucose will have brick red precipitate with Benedict solution, and proteins will have reddish brown color with Millon's reagent.
Why reagents are used to test compounds?The reagents when combined with specific compounds performs specific reaction which helps to determine the presence of particular compound.
In the given activity,
If in the first test, if the iodine turns color to blue this will indicate the presence of starch.In the second test, if on adding Benedict solution, brick red precipitates formed, this indicates the presence of glucose.In the third test, on adding Millon's reagent the protein in the solution will form reddish brown color.Thus, these were some inferences that can be made from the given activities.

Algae are the primary producer in the trophic levels. Therefore, option "C" is correct.
What are tropic levels?Tropic levels are the levels or steps in the food chain. In tropic levels, the energy is transferred to different levels through food produced by the lower levels. The source of nutrition varies in different food chains.
There are four types of tropic levels, first primary producers are the autotrophs which produce their own food. Second, are herbivores which consume the autotrophs also called primary consumers. Third are secondary consumers who are carnivores and fourth are the tertiary consumers who are also carnivores.
example: sun, plants, deer, and tigers.
Tropic levels play a key role in understanding the flow of energy.

in step 1 of protein synthesis describe two of the differences between the DNA template and its complementary RNA molecule
Answer:Proteins are synthesised (made) by the ribosomes using messenger RNA transcribed from DNA in the nucleus.
Explanation:
In every eukaryotic cell, such as plants and animals, there is DNA in the nucleus. The nucleus is an area surrounded by a membrane (nuclear membrane) which has some pores for materials to enter and exit, but these are controlled. The DNA is the cell's instructions, it is a series of code that can be transcribed and translated to make proteins. As in the image below DNA is a series of bases attached to a sugar phosphate backbone and bonded to another base pair to made a ladder, this ladder is twisted making the shaped called a double helix . There are four base pairs: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). The bases have bases they bond to making complementary base pairs , A and T bond together while the C and G bond together. on each strand of DNA one end is labelled 5' (read as 5 prime) and other end is the 3'. The 5' end base pairs of one strand are always attached to the 3' end of the complementary strand. Labelling the ends helps us to describe in which direction DNA is read.

answer, include fossils in the same layer of rock, in a lower layer of rock, and in a higher
layer of rock compared to an index fossil.
Answer:
Index fossils are fossils of organisms that lived during only one short period of time. A layer rock with an index fossil in it is close in age to another layer of rock with the same type of index fossil in it.
