DNA copying is otherwise known as DNA replication which is the process of producing 2 identical copies of DNA from one original DNA molecule during cell division. DNA copying is important because it generates variation during sexual reproduction which leads to evolution. Also, DNA copying helps in transfer of information or characters from the parents to the offsprings.
Mendel studied traits with only one mode of inheritance in pea plants. The inheritance of the traits he studied all followed the relatively simple pattern of dominant and recessive alleles for a single characteristic. There are several important modes of inheritance, discovered after Mendel’s work, that do not follow the dominant and recessive, single-gene model.

Label the parts of the microscope shown in the picture below using the following terms: coarse adjustment knob, eyepiece (or ocular lens), fine adjustment knob, light condenser and iris diaphragm, objective lenses, stage
Answer:
A is the eyepiece (or ocular lens), B is the objective lenses, C is the iris diaphragm, D part is refers to light condenser, E is the location of fine adjustment knob and F is the location of coarse adjustment knob.
Explanation:
A is the eyepiece (or ocular lens), B is the objective lenses, C is the iris diaphragm, D part is refers to light condenser, E is the location of fine adjustment knob and F is the location of coarse adjustment knob. All these parts are the important parts of microscope which has a specific function in the microscope. Without one of these parts, we can not see the microbes in the microscope.

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.

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.

How do light intensity and distance affect the rate of photosynthesis? How do you know?
Answer:
Light provides the energy needed for photosynthesis. Increasing the light intensity increases the rate of photosynthesis, provided plenty of carbon dioxide and water are available. ... This states that the intensity of light is inversely proportional to the square of the distance from the source.

How did the evolution of photosynthetic prokaryotes affect the level of oxygen in the atmosphere?
Answer: effects of the evolution of photosynthesis. Photosynthetic organisms dramatically increased atmospheric oxygen levels between 2 and 2.5 billion years ago. This change created selective pressure favoring organisms that used oxygen to produce energy-containing molecules.

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.
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.
