10. What are two examples of "typos" that happen when DNA is being copied?
Answer:
DNA “typos” cause variation
Explanation:
Any time DNA is copied, a mistake or change can occur in the letters of the DNA sequence, or gene. These changes result in variations or differences in DNA from person to person.
The "typos" that happen when DNA is being copied is mutations and variations.
What are mutations?A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke.
Moreover, mutations result either from errors in DNA replication or from the damaging effects of mutagens, such as chemicals and radiation, which react with DNA and change the structures of individual nucleotides.
Therefore, mutations within the DNA are a fairly common event. Mutations are random changes that occur within the sequence of bases in DNA. They can be large scale, altering the structure of the chromosomes.

Explanation:
You are maintaining a small population of fruit flies in the laboratory by transferring the flies to a new culture bottle after each generation. After several generations, you notice that the viability of the flies has decreased greatly. Recognizing that small population size is likely to be linked to decreased viability, the best way to reverse this trend is to cross your flies with flies from another lab.

Environmental degradation must be reduced, so by the baseline data of the world's ecosystem must be researched.
What is the world's ecosystem?Ecosystem defines the interaction between living (biotic) components and nonliving (abiotic) components. A living system depends on nonliving factors around them.
Temperature, soil, and light are all components that are necessary for the living system to reproduce and survive. Plants can not do photosynthesis without light and also get minerals and water from the soil.
We need to understand the baseline of the world's ecosystem, so climate-changing conditions can be reduced. Global warming is a critical condition for the ecosystem and can be reduced by research.
Therefore baseline data on the world's ecosystem must be researched to improve environmental conditions.

Which of the following choices is not among the most common cell shapes found in prokaryotes?
оооо
Cocci (spherical)
Bacilli (rod-shaped)
Spirochetes (spiral-shaped)
Recticuli (rectangular)
Answer:
Recticuli(rectangular)
"Recticuli (rectangular)" is not among the most common cell shapes found in prokaryotes. Therefore, option (D) is correct.
Rectangular cells, represented by "Recticuli" in your options, are not among the most common cell shapes found in prokaryotes. Prokaryotes are primarily characterized by cocci (spherical), bacilli (rod-shaped), and spirochetes (spiral-shaped) forms. Cocci are typically round, bacilli are elongated rods, and spirochetes exhibit a spiral or helical structure.
These shapes facilitate various functions such as movement, attachment, and replication. Rectangular cells, while theoretically possible, are not commonly observed in natural prokaryotic populations. The lack of real-world prevalence could be attributed to the structural challenges and limited advantages of such a shape in prokaryotic environments. The prevailing shapes have likely evolved due to their practical benefits, underscoring the connection between form and function in these microorganisms. Therefore, option (D) is correct.

The air we breathe is mostly a mixture of oxygen and nitrogen. How do air molecules change when they reach altitudes above 100 km?
I need to make sure the answer I have is right.
As you increase in altitude, there are fewer air molecules. Due to the lower amounts of air molecules, the atmospheric pressure decreases causing the air to be harder to breath in.

The greatest number of relationships between the
organisms in an ecosystem is best shown in
A. a food chain
B. an energy pyramid
C. a food web
D. an ecological succession diagram
The greatest number of relationships between the organisms in an ecosystem is best shown in a food web. Thus, the correct option is C.
What is a Food web?A food web consists of all the food chains which are present in a single ecosystem. Each of the living thing in an ecosystem is a part of multiple food chains. Each food chain is one possible path that energy and nutrients may take as they move through the ecosystem.
For example- A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. It is a food web that shows the many different paths plants and animals are connected.
Therefore, the correct option is C.

How does 02 enter the mitochondria
How does oxygen enter the mitochondrial matrix? The electrons taken from NADH and FADH are passed to several other proteins in the inner mitochondrial membrane. Ultimately, they are passed to oxygen (O2). O2 becomes two molecules of water (H2O) after receiving four electrons. This is how oxygen is used by cell respiration.
