Answer:
many humans have been destroying these biomes over the years.
Forest biome: It gives us medicinal plants, woods for commercial purpose. Forests provides us rubber and fibers that is very important for the industries for making various products. They also contribute to perform ecological functions such as carbon storage, nutrient cycling, water and air purification. It also provides habitat to the wildlife.
Freshwater biome: We use fresh water for drinking water, irrigation, sanitation systems, and in industrial factories. Water used from groundwater, rivers and lakes is regained by rain and snowfall.
Marine biome: It serves huge amount of oxygen into the environment and absorbs the atmospheric carbon dioxide.
As a result of the activity of human there is a significant decrease in the number of trees. The products now used are synthetically made which were made up of natural fibers previously. The water source such as rivers, lakes, and ponds are polluted due to which many water borne diseases are increasing day by day. The accumulation of waste which are found in marine biome are reducing the number of flora present inside marine ecosystem.
The forest biome, freshwater biome, and marine biome are vital to living organisms because they provide food, oxygen, and medicines, among other things. Human activities are destroying the biomes and having many negative impacts in these biomes.
What are the negative impacts on the biome?biome, such as the plants present in the forest biome, take carbon dioxide and make glucose and oxygen with the help of sunlight, and this is the major source of food for all heterotrophs (both animals and humans). Humans use those raw materials and convert them into usable products; animals and plants are used for medicines, food, etc.
Because water makes up the majority of the Earth, oceanic plankton and animals are responsible for the majority of carbon fixation. The freshwater biome is important for drinking water, for edible fish and shrimp, for factories, for bathing, etc., but human activities induce forest fires and make the water polluted.
Hence, although all these are important, humans negatively affect them.

Which type of soil is most likely to be found in horizon E?
A. A layer of bedrock
B. A layer of decayed plant matter
C. A layer of parent material
D. A layer of pale, Sandy soil lacking clay and iron
Answer:
D. A layer of pale, sandy soil lacking clay and iron
Explanation:
The soil is complex, composed of multiple layers/horizons all of which have different characteristic that make every horizon to have its own special role in it. The horizon E is the third horizon from the top. This horizon is characterized by being mostly sandy, and because the water manages to go through it very easily it is a horizon in which there's heavy leaching going on. Because of the leaching, this horizon loses the clay, iron, and aluminium from it, thus they accumulate in the horizon below it. As a horizon it is very important, especially for the trees, as their root systems manage to develop very well in this horizon because it is loos and sandy.
Answer:
D. A layer of pale, sandy soil lacking clay and iron

why would imbalance hormone levels cause a male to be unable to reproduce
Answer:
Many Reasons
Explanation:
For starters, low T - or low Testosterone can lead to low libido, which may physically cause him not to want to reproduce. Low T can also have detrimental effects to the fidelity or health of sperm cells, as testosterone is necessary for the proper maturation of sperm. That means then, that at the cellular level if you have unhealthy sperm then they may not be able to fertilize an egg.

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.
Which statement accurately describes the movement of Earth's plates due to convection currents?
Material near the core cools as heat is transferred toward the crust.
Heated materials become denser, causing them to rise toward the surface.
As heated material gets closer to the surface, it begins to cool,
As materials cool, they become less dense and sink back toward the core.
Answer:
As heated material gets closer to the surface, it begins to cool
Explanation:
The core and surface have very different temperatures where the core is extremely hot as compared to the surface. When mantle gets heated as it passes near the core, it rises towards the surface. When it reaches the surface, it begins to cool and becomes more dense. The cooled magma then starts to sink down back near the core where it gets heated again and rises. This is what drives convection currents.
The Earth's plates move as a result of convection currents, with hot material rising towards the crust, cooling, becoming denser, and sinking back towards the core; a continuous cycle that drives plate tectonics.
Explanation:The movement of Earth's plates is largely driven by convection currents within the Earth's mantle. Material near the core becomes heated and becomes less dense, causing it to rise towards the crust. This is reflected in the statement 'Heated materials become less dense, causing them to rise toward the surface'. Once this heated material gets closer to the surface, it begins to cool and becomes denser. This is referred to in the statement 'As heated material gets closer to the surface, it begins to cool'.
As it cools, the material becomes denser and sinks back towards the core, as referenced in the statement 'As materials cool, they become less dense and sink back toward the core'. This continuous cycle of heating, rising, cooling, and sinking causes the movement of Earth's plates.

Answer:
economy
Explanation:
Whichever country do we look at, there is a strong relationship between the quantity of energy that the country uses and the size of its economy. The more developed and the larger the economy of a country is, the more energy is demanded for the economy to be driven. This leads to high demand for certain natural resources that produce energy, as the industry needs power in order to function. We can easily see this if we take in consideration the biggest economies in the world, USA, China, Japan, Germany, UK, France, and then if we see how much energy each of them uses, so we will come to a conclusion that the biggest economies are the biggest users of energy.

Drinking water is example of maintaining homeostasis.
Explanation:
Homeostasis is the ability of a system to remain in equilibrium in terms of temperature or to maintain other physiological features. Since the sweating is responsible for cooling down the elevated body temperature hence drinking water can help in maintaining homeostasis. Homeostasis is a state where the proper functioning of body can take place. If the body is out of homeostasis or equilibrium then the function of the body will not be able to execute properly.
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.

Archaebacteria are the prokaryotic anaerobic bacteria.
Explanation:
Archaebacteria are the prokaryotic bacteria. They live in an extremely harsh environment. They are different from the other bacteria with some characters like their habitat. Their cell wall don't have peptidoglycan like other bacteria. Archaebacteria are resistance to penicillin and some other antibiotics. These are of three groups such as methanogens, Halophiles, and thermoacidophiles.
Methanogens are methane-producing bacteria and used as fuel. Halophiles are found in saline water and heavy salt concentration. They contain red carotenoid pigment in the cell. So they appear red. Thermoacidophiles can live in extremely high temperatures and high acidity.
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.
