Explain how dna polymerase chooses which nucleotides to put into the new strand. Be specific and detailed in your explanation of how this selection is accomplished to make the correct dna molecule
DNA polymerase adds nucleotides at the 3' primer end of the DNA. This DNA polymerase checks the newly added base has correctly paired with the base in the template strand or not. Based on this it adds the new nucleotide.
What is nucleotide?Nucleotide is the nucleoside with a phosphate group. It generally stack or link with each other to make a polynucleotide chain.
DNA polymerase adds these nucleotides one by one to the 3' primer end on the DNA strand.
It usually checks the correct pairing of the base with the template strand and then adds the new nucleotide to it.
Thus, by this step DNA polymerase choose nucleotides to put into the new strand.

Why do large-scale convection currents occur in the atmosphere?
Explanation:
Convection drives the circulation of air in the earth's atmosphere. The sun heats the air near the earth's equator, which becomes less dense and rises upward. As it rises, it cools and becomes less dense than the air around it, spreading out and descending toward the equator again.

Describe the relationship between a thermal inversion and pollution.
Answer:
With a stronger inversion (greater thermal difference between inversion and mixing layers), less pollution can disperse into higher atmospheric levels. Likewise, the longer an inversion lasts, the more pollution will build up, and the worse the air quality in the mixing layer will be

The illustration shows an ocean food chain and the concentrations of the toxin DDT at each trophic level. What conclusions can be made as to how DDT impacts this food chain? Include where the concentration of DDT is likely to be lowest, and where it is likely to be highest
DDT increases as it moves up a food chain.
Explain how?DDT increases or biomagnifies if we look at a food chain. DDT is fat-soluble, which means animals store it in fatty tissues. It also takes a relatively long amount of time to break down.
Thus, if a predator consumes multiple organisms and each organism has a small amount of DDT, the amount of DDT in the predator is going to be the result of all of those small amounts combined.

n this experiment, you need to examine the idea of thermal energy transfer. Using a controlled experiment, what might a good question about the variables that affect thermal energy transfer be? Thermal energy transfer depends on many properties, but limit your question to only two.
The thermal conductivity and temperature difference between the surrounding plays a crucial role in the transfer of thermal energy between the materials.
What are the three modes of thermal energy transfer?The three modes of thermal energy transfer include conduction (direct contact of atoms), convection (migration of warm particles), and radiation (migration of electromagnetic waves).
The first property is thermal conductivity. Examples include a cube of ice when positioned in the hand of a man. It causes the ice to melt via the thermal conduction from men's hands.
The second property is the temperature difference. Examples include when a hot cup of tea mingled with a cold glass of water. It changes the temperature to a new value which is different from the exact temperature of both initial fluids.
Therefore, it is well described above.

why osmosis is special case of diffusion?
Answer:
Diffusion can be called as osmosis in some cases because if the substance is liquid and passes through a semi-permiable membrane then its osmosis.
WELCOME!
Answer:
Osmosis is a special kind of diffusion because in both cases there is a movement of particles from a higher concentration region to a lower concentration region. The only difference is that osmosis is applicable to the movement of the solvent only through the semi-permeable membrane where the solvent is water.

Write a paragraph explaining how genetic variation, reproductive strategies and environmental pressures have impacted the survival of populations. Identify a specific example for each in your discussion.
Answer: Genetics and Pressures
Explanation:
For natural selection to occur, a population must have a wide variety of individuals with different traits. For example, natural selection would not influence fish body color if all individuals in a population were exactly the same color. Variation of scale color can help a fish species have a higher chance of survival by confusing predators as to what species they are.
Reproductive strategies represent a set of behavioral, morphological, and physiological adaptations that facilitate access to potential mates, improve the chances of mating and fertilization, and enhance infant survival. Male peacocks have bright, big tail feathers, for example, to attract females. If an organism has a high appeal, this will make them more likely to be able to meet and continue the survival of the species.
Environmental pressures, such as plant death, could influence the survival of herbivorous organisms. Say a small land creature consisted off grass, and an epidemic killed all the grass in their region. They would either die off, or they would evolve to find different types of food. The former could reduce population, while the latter could increase it.
Why is knowing agricultural statistics, background information, and soil characteristics about the territory in which your farm is located important?
Knowing the agricultural statistics of where your farm is located is important because it can help a farmer to identify the efficiencies that will lead to more productivity and profitability, less input costs, and optimized fertilizer use. The background information is important to farmers because it helps a farmer know whether or not the ground is good for growing crops, if something had happened to the land before their use. Soil characteristics are important to farmers because fertile soil is important for crop growth. The soil needs to be able to allow water and air to infiltrate, roots to be able to move more, and for biota to be able to thrive.

Almost 40% of the world population and many ecosystems are suffering from water scarcity. Many actions taken in the past have led to the water shortage being experienced today. Evaluate each of the factors listed below. All of these have led to water scarcity EXCEPT: A) sea-level rise B) population growth agricultural demand D) climate change, including drought
Answer:
Water scarcity already affects every continent. Around 1.2 billion people, or almost one-fifth of the world's population, live in areas of physical scarcity, and 500 million people are approaching this situation. Another 1.6 billion people, or almost one quarter of the world's population, face economic water shortage (where countries lack the necessary infrastructure to take water from rivers and aquifers).
Water scarcity is among the main problems to be faced by many societies and the World in the XXIst century. Water use has been growing at more than twice the rate of population increase in the last century, and, although there is no global water scarcity as such, an increasing number of regions are chronically short of water.
Water scarcity is both a natural and a human-made phenomenon. There is enough freshwater on the planet for seven billion people but it is distributed unevenly and too much of it is wasted, polluted and unsustainably managed.

Which of the following is NOT a result of global warming?
(societal conflicts)
(sea-level rise)
(loss of biodiversity)
(ozone depletion)
Ozone depletion is NOT a direct result of global warming. While both global warming and ozone depletion are environmental concerns, they are caused by different factors and have distinct impacts.
Global warming is primarily caused by the increased concentration of greenhouse gases in the atmosphere, trapping heat and leading to a rise in global temperatures. It results in a wide range of consequences, including the melting of polar ice caps, rising sea levels, extreme weather events, shifts in ecosystems, and the potential loss of biodiversity as species struggle to adapt to changing conditions.
On the other hand, ozone depletion is mainly caused by the release of certain chemicals known as ozone-depleting substances (ODS) such as chlorofluorocarbons (CFCs) and halons. These substances break down ozone molecules in the stratosphere, leading to the thinning of the ozone layer. Ozone depletion primarily affects the stratospheric ozone layer, which shields the Earth from harmful ultraviolet (UV) radiation. The thinning of the ozone layer can have detrimental effects on human health, ecosystems, and agricultural productivity.
Therefore, while global warming and ozone depletion are both significant environmental issues, ozone depletion is not a direct result of global warming.
