what did not occur in the Proterozoic eon?
A. The oxygen level increased greatly in the atmosphere
B. The emergence of Eukarya
C. Multi-celled eukaryotic organism began to diversify
D. anaerobic bacteria kept thriving with more oxygen
Answer:
C. Multi-celled eukaryotic organisms began to diversify
Explanation:
The Proterozoic is an eon in which numerous important things occurred. There were multiple organisms that appeared in this eon. They were able to perform the process of photosynthesis which resulted in gradual pilling up of oxygen into the atmosphere, thus changing the composition of the atmosphere, and setting up the terrain for the future development of other organisms. It is an eon though in which there were only single-celled organisms, while the diversification of multi-celled eukaryotic organisms occurred in the next eon, the Phanerozoic.
During the Proterozoic Eon, the increase in atmospheric oxygen from cyanobacterial photosynthesis led to the extinction of many anaerobic bacteria; thus, D ('anaerobic bacteria kept thriving with more oxygen') did not occur in the Proterozoic eon.
The Proterozoic Eon was a period of significant atmospheric changes, including the Great Oxygenation Event (GOE). This event was characterized by the rise in atmospheric oxygen due to the photosynthetic activity of cyanobacteria, which transformed Earth's anoxic atmosphere. This increase in oxygen led to drastic environmental changes and affected different organisms in various ways.
Answering the question, what did not occur in the Proterozoic eon, option D (anaerobic bacteria kept thriving with more oxygen) is incorrect. As the oxygen levels increased, many anaerobic bacteria were decimated because they could not survive in the presence of free oxygen. On the other hand, aerobic organisms thrived and evolved under these new oxygen-rich conditions.

what is the main difference between animal cell and plant cell?
There are a few differences between plant and animal cells. One major difference is their structure; animals are enclosed by a cell membrane, but plant cells have a cell membrane and a cell wall to give them a more solid form. Another major difference is that plant cells have chloroplasts for photosynthesis whereas animal cells do not because they do not undergo photosynthesis.
Hope this helps!!
The main difference between animal and plant cells is that plant cells have a cell wall, chloroplasts, and a large central vacuole, which are absent in animal cells. However, animal cells have centrioles and lysosomes, not usually found in plant cells.
Explanation:The main difference between an animal cell and a plant cell lies in a few key structures. Plant cells have a cell wall, chloroplasts, and a large central vacuole, which are not found in animal cells. The cell wall provides additional support and protection to the plant cell. Chloroplasts are where photosynthesis takes place, and the central vacuole stores water and maintains the cell's turgor pressure.
On the other hand, animal cells have centrioles and lysosomes, which are usually not found in plant cells. Centrioles help in cell division, and lysosomes help in digestion and waste removal.

A study has shown that Scotland's river otter population is increasing after falling
sharply over the last 40 years.
Otters live along the banks of rivers, usually in reeds and gaps between tree roots.
Fish are their main food.
What term is used for the place where otters live?
Answer:
An otter's den is called a holt or couch.
Explanation: Otters are found almost all over the world and in many wet habitats, such freshwater rivers, lakes, oceans, coastlines and marshes. Most otters live in dens — built by other animals, such as beavers — that are dug into the ground that have many channels and dry inner chambers
Final answer:
The place where otters live is called their habitat, which includes river banks with reeds and spaces between tree roots.
Explanation:
The term used for the place where otters live is habitat. River otters typically inhabit environments along the banks of rivers, which provide essential resources such as food, shelter, and a suitable place for raising their young. The main food for otters is fish. Otter habitats include areas with abundant reeds and spaces between tree roots where they can hide and rest. The health and stability of otter populations, like that in Scotland, indicate the overall health of the ecosystem, including the availability of clean water and sufficient prey like fish in kelp beds, and the absence of excessive predation or environmental stressors.

Which of these is a disadvantage of hydropower?
Answer:
Fish populations can be impacted if fish cannot migrate upstream past impoundment
dams to spawning grounds or if they cannot migrate downstream to the ocean. Upstream fish passage can be aided using fish ladders or elevators, or by trapping
and hauling the fish upstream by truck. Downstream fish passage is aided by
diverting fish from turbine intakes using screens or racks or even underwater lights
and sounds, and by maintaining a minimum spill flow past the turbine.
Hydropower can impact water quality and flow. Hydropower plants can cause low
dissolved oxygen levels in the water, a problem that is harmful to riparian
(riverbank) habitats and is addressed using various aeration techniques, which
oxygenate the water. Maintaining minimum flows of water downstream of a
hydropower installation is also critical for the survival of riparian habitats.
Hydropower plants can be impacted by drought. When water is not available, the
hydropower plants can't produce electricity.
New hydropower facilities impact the local environment and may compete with other
uses for the land. Those alternative uses may be more highly valued than electricity
generation. Humans, flora, and fauna may lose their natural habitat.
Hope This Helps! Have A Nice Day!!
Final answer:
Hydropower has disadvantages such as loss of forest habitat, decomposition of plant material increasing water acidity, and blocking species dispersal which can degrade ecosystems and harm migratory fish.
Explanation:
Disadvantages of Hydropower
One of the disadvantages of hydropower is the environmental impact associated with dam construction and maintenance. Hydropower dams cause loss of forest habitat as extensive areas, including tropical rainforests, can get flooded. This not only destroys the home for many tropical organisms but also affects other land uses and indigenous communities. The decomposition of plant material in reservoirs can increase the water's acidity, leading to erosion of turbines and reducing their lifespan. Additionally, issues like blocking species dispersal, particularly for migratory fish, and sediment buildup behind dams can degrade the ecosystem and lower the beneficial use of these structures.

The Krebs cycle and electron transport processes take place within the _____.
mitochondria
lysosome
vacuole
cytoplasm
The answer is Mitochondria
Answer:
The correct answer is: mitochondria.
Explanation:
The Krebs Cycle and the Electron Transport processes are part of a much bigger process with the intent to generate energy for the cell, Cellular Respiration. Cellular Respiration is basically a series of metabolic reactions that produce ATP molecules using glucose as a substrate.
Both the Kreb Cycle and the Electron Transport Chain occur inside the mitochondria. The first two steps of Cellular Respiration, Glycolysis and Pyruvate decarboxylation, happen in the cytosol and the mitochondria, respectively.
Mitochondria are the organelles responsible for ATP synthesis, though they also function as a calcium reservoir, and participate in processes like apoptosis and synthesis of steroids.
Lysosomes are organelles that contain hydrolytic enzymes that break down polymers. Vacuoles (mostly found in plant cells) are vesicles filled with water that also contain materials that can be harmful to the cell. The Cytoplasm is all the material within a cell except for the nucleus.

17. The enzyme DNA polymerase works only in the 5' to 3' direction. How does this affect the leading strand and the lagging strand?
O A. DNA polymerase can use only the leading strand as a template. A different enzyme is used to synthesize DNA on the lagging strand
O B. DNA polymerase can work on both the leading and the lagging strand but is much faster on the leading strand
O C. DNA polymerase can work continuously on the leading strand but must flip the lagging strand around before it can work on it
O D. DNA polymerase can work continuously on the leading strand but works discontinuously on the lagging strand, creating Okazaki fragments.
Answer:
D
Explanation:
This is because the two DNA strands run antiparallel to each other. This means that as the DNA polymerase replicates the leading strand from 5’ --> 3’, the lagging strand is oriented in the 3’ --> 5’ which makes it difficult for a continuous replication like that of the leading strand. The DNA polymerase has evolved a mechanism to replicate the lagging strand discontinuously using many primers. This generates many fragments called Okazaki fragments that are ligated together to form one complete strand.
