Summarize how the overharvesting of a single species,such as baleen whales,can affect an entire ecosystem.
Answers
Answer:
Overharvesting can have a negative impact on an entire species because it can alter food web relationships. For example, if there are too many whales, many organisms may lose their food source and homes, or even worse, go extinct!Source:

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)
Answers
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.

There are two stages to photosynthesis: Reactions of light and darkness. Light-Reaction takes place in thylakoid membrane.
What is Light-Reaction takes place during Photosynthesis?Autotrophic plants produce their own food through a process called photosynthesis. Sunlight, chlorophyll, CO2, and water are four crucial components needed for this process. It is a response that is light dependent.
In plants and some other creatures, a process known as the "Dark Reaction" harnesses the energy from the sun to change carbon dioxide and water into glucose (a sugar) and oxygen.
Therefore, a sequence of chemical events known as the "Light Reaction of Photosynthesis" are what is needed for the pigment found in leaves, such as chlorophyll, to transform light energy into chemical energy in the form of ATP and NADPH.

How does 02 enter the mitochondria
Answers
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.

10. What are two examples of "typos" that happen when DNA is being copied?
Answers
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.

Which statement about US greenhouse gas emissions is supported by the bar graph? Emissions decreased every year between 2005 and 2014. Emissions increased substantially between 2005 and 2014. After peaking in 2007, emissions dropped every year through 2014. After peaking in 2007, emissions went up and down through 2014.
Answers
Countries often have records of gas emissions in their county. The statement about US greenhouse gas emissions is supported by the bar graph is that after peaking in 2007, emissions went up and down through 2014.
Greenhouse gas emissions often takes place due to the activities of human. These activities acts as a catalyst to powerup the greenhouse effect, causing climate changes.Recorded data of gas emissions has shown that after it peaked in 2007, reduction is said to be of averaged 1.3% per year but the data of U.S. energy-related CO2 emissions in 2019 shows that it was 1.8% greater than in 1990.
