Answer:
Mutations affect organisms in two different ways. Genetic mutations are inherited DNA changes that can be passed on to the next generation. Somatic mutations are DNA changes that are acquired after birth. Mutations can be helpful, harmful or make no difference at all.

After examining the fossil record, scientists have determined that scorpions today are much smaller than their extinct ancestors. For example, Jaekelopterus rhenaniae, a giant scoprtion species that lived 255 million to 460 million years ago was 2.5 meters long. Which of the following conclusions is supported by this information?
A. scorpions living today have increased their numbers since they first appeared
B. scorpions in the fossil record are smaller than their descendants are
C. scorpions have changed as a result of natural selection
D. scorpions do not appear in their original state in the fossil record
Answer: C. scorpions have changed as a result of natural selection
Explanation:
The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.
The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.
The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.
The small finches on the Galapagos islands lived on islands with slightly different habitats. How did these varied habitats affect the evolution of the finches on different islands?
Adaptations - Darwin's Finches. Here are some adaptations of particular finches and the finches as a whole. ... The birds with bigger beaks survived, and the rest adapted by having developed strong and big beaks, or developed beaks that allow them to use tools to reach their food.
Hope it helps...
These varied habitats results in adaptive radiation which is responsible for evolution of the finches on different islands.
What is evolution?"Evolution is change in the heritable characteristics of biological populations over successive generations."What is adaptive radiation?"Adaptive radiation is a process in which organisms diversify rapidly from an ancestral species into a multitude of new forms, particularly when a change in the environment makes new resources available."The small finches had to change its type of nutrient(eating seeds, small worms, etc.) in order to survive on the varied habitats of island. This results in their evolution.
Hence, adaptive radiation occurs due to varied habitats.

The cells that make xylem have an ability to adapt according to the environment. They open up, lose their ends to make a hollow vessel, and they get strength by lignin, it also supports the plant.
What is xylem vessel?Xylem vessel is a vessel type structure present in plants, that hold water for the plant. They are small vessels, and they loose and tight according to the requirement of water of the plant.
Its main function is to transport water and nutrition. It also supports the plant and give strength to tissues and stems.
Thus, the cells that make up xylem have the ability to adapt to their surroundings. They open up, shed their ends to form a hollow vessel, and lignin provides strength and support to the plant.

This fly has 14 chromosomes in its cells.7 maternal chromosomes and 7 paternal chromosomes.Assume you are a microscopist viewing this fly cells that are undergoing meiosis. Conclude the number of chromosomes/chromatids at the end of meiosis 1 as well at the end of meiosis 2
Answer:
23 pairs in meiosis 1 and 23 numbers in meiosis 2.
Explanation:
There are diploid number of chromosomes means double number of chromosomes at the end of meiosis 1 while on the other hand, at the end of meiosis 2, there are haploid number of chromosome means half number of chromosomes in each daughter cell. In humans meiosis 1, there are 23 pairs of chromosomes that is diploid in nature but in the end of meiosis 2, there are only 23 chromosomes in each daughter cell which is haploid in nature.
How did the evolution of photosynthetic prokaryotes affect the level of oxygen in the atmosphere?

Take a look at the two boxes below. Each box has the same volume. If each ball has the same mass, which box 1 or 2 would weigh more? Why?
Answer:
Box 1.
Explanation:
The box 1 have the more mass because there are more number of balls present in the box while on the other hand, box 2 has less number of balls in the box. The volume of box boxes are the same as well as weight of the both boxes before placing of balls in it. Placing of balls changes the weight of both boxes because of the presence of different number of balls in each boxes that increases its weight.
