Here is a chart that with the pairs

Explanation:

The base pairing in DNA and RNA involves the complementary pairing of nitrogenous bases. Adenine pairs with thymine in DNA and with uracil in RNA, while cytosine pairs with guanine in both DNA and RNA. Hydrogen bonds stabilize the base pairs.

The base pairing in DNA and RNA involves the complementary pairing of nitrogenous bases. In DNA, adenine (A) always pairs with thymine (T), and cytosine (C) always pairs with guanine (G). This is known as Chargaff's rule. Similarly, in RNA, adenine (A) pairs with uracil (U), and cytosine (C) pairs with guanine (G).

For example, if one strand of DNA has the sequence AGTGCCT, the complementary strand would have the sequence TCACGGA.

The base pairs are stabilized by hydrogen bonds, with adenine and thymine forming two hydrogen bonds, and cytosine and guanine forming three hydrogen bonds.

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.

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.

Answer:

B. precipitation

Explanation:

Bogs refer to the wet and muddy ground that mostly consist of dead plants and mosses undergoing the process of decomposition. Bogs receives its water from precipitation. Various sources of precipitation are rain, snow, hail, sleet etc. So, unlike swamps and marshes, all these forms of precipitation impart water to bogs.

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.

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.

Instantaneous speciation is a type of sympatric speciation which refer to the sudden development of new species from one generation which is isolated reproductively or ecologically from the parent species which has the ability to reproduce and establish new population. It occur by polyploid i.e producing two or three sets of homologues chromosomes.

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.

Answer: before 1850

Explanation:

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.

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.

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.

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.
