Answer:
Phosphate group
Explanation:
Each nucleotide consists of a heterocyclic base linked via a five-carbon sugar (deoxyribose or ribose) to a phosphate group. DNA and RNA each contain four different bases. The purines adenine (A) and guanine (G) and the pyrimidine cytosine (C) are present in both DNA and RNA. So both DNA and RNA have four nitrogenous bases each—three of which they share (Cytosine, Adenine, and Guanine) and one that differs between the two (RNA has Uracil while DNA has Thymine). One of the most significant similarities between DNA and RNA is that they both have a phosphate backbone to which the bases attach.
All nucleotides of DNA and RNA contain a phosphate group. Hence, option D is correct.
What do you mean by Nucleotides?Nucleotides may be defined as the components of nucleic acids. It is composed of a phosphate group, a nitrogenous base, and sugar.
Uracil base is present in RNA, thymine base is present in DNA, ribose sugar is found in RNA, while deoxyribose sugar is found in the DNA.
Therefore, all nucleotides of DNA and RNA contain a phosphate group.

How can landforms affect weather??
Answer:
hope it helps! love uuwu
Explanation:
These effects can cause huge changes in the temperature, precipitation, and humidity of a region. An example is when a storm encounters a mountain range. The clouds can not go over the mountains, so the upwind side receives plentiful rainfall while the downwind side gets little to no rain
Huge bodies of water absorbs and releases heat in a very slow cycle. ... This causes a large difference in temperature at night and day on land or around bodies of water. This constant heating and cooling affects wind and rain. Role of landforms to global temperature and weather.

Which of the following are biofuels? Select all that apply*
Coal
Petroleum
Natural gas
Ethanol
Biodiesel
Answer:
Biofuels have been around longer than cars have, but cheap gasoline and diesel have long kept them on the fringe. Spikes in oil prices, and now global efforts to stave off the worst effects of climate change, have lent new urgency to the search for clean, renewable fuels.
Our road travel, flights, and shipping account for nearly a quarter of the world's greenhouse gas emissions, and transportation today remains heavily dependent on fossil fuels. The idea behind biofuel is to replace traditional fuels with those made from plant material or other feedstocks that are renewable.
But the concept of using farmland to produce fuel instead of food comes with its own challenges, and solutions that rely on waste or other feedstocks haven't yet been able to compete on price and scale with conventional fuels. Global biofuel output needs to triple by 2030 in order to meet the International Energy Agency's targets for sustainable growth.

Explanation:
Answer:
Global warming and climate change are two of the most pressing issues facing our planet today. The increase in temperature and changes in weather patterns have caused a significant impact on the environment and the different regions of the world.
In the Arctic, the ice is melting at an alarming rate, leading to rising sea levels. This has devastating effects on the wildlife that depend on the ice for survival. Polar bears, for example, are struggling to find food as the ice they hunt on disappears.
In Africa, climate change is leading to droughts and food shortages. This is particularly devastating for the millions of people who depend on agriculture for their livelihoods. Without adequate rainfall, crops fail, leading to famine and displacement.
In Southeast Asia, rising sea levels and more frequent storms are causing coastal erosion and flooding. This is leading to the loss of land and homes, as well as damaging critical infrastructure such as power plants and hospitals.
Overall, global warming and climate change are causing significant damage to the environment and the people and animals that depend on it. Urgent action is needed to mitigate the effects of these phenomena and prevent further damage to our planet.

What do your muscle cells do when they run out of oxygen for respiration?
Explanation:
When your muscle cells run out of o2 4 respiration, it relies on stored fat or lipids for energy..(glycolysis) ...
Normally this transition does not last long because muscles also depend on glucose for energy..
When muscle cells run out of oxygen for respiration, they switch to anaerobic respiration, producing lactic acid as a byproduct.
When oxygen runs gone, muscle cells switch to anaerobic respiration. Aerobic respiration generates ATP from oxygen. Muscle cells switch to anaerobic respiration during severe activity or low-oxygen settings.
Muscle cells use glucose to respire anaerobically. Glycolysis generates ATP, although less efficiently than aerobic respiration. Lactic acid, a consequence of anaerobic respiration, can build up in muscles and cause tiredness, discomfort, and burning.
Anaerobic respiration offers short-term energy but is unsustainable. Muscle cells will resume aerobic respiration to efficiently create ATP and remove lactic acid once oxygen is available.

It takes 600 J of work to lifta crate straight up but 1,200 Jto pushthat crate up a ramp to the same height. What's the efficiency of the ramp?
Answer:
50 percent
Explanation:
The efficiency of ramp can be found by using this formula
(Output work/input work)*100.
Amounts of work to lift up = 600j
Amount of work bro take up to same height = 1200j
Efficiency of ramp = (600j/1200j) * 100
= 0.5 x100
= 50 percent
Therefore from the calculations above, the efficiency of this ramp is 50 percent

What is the relationship between force, mass, and motion?
Answer: If an object is accelerating, then Force = Mass x Acceleration. If it is moving at a constant speed, then Kinetic Energy = 1/2 mass x velocity squared but in this case, there is no force acting on the object. Perhaps this will help understand the relationship between force and mass. Force is anything that acts on an object, from a person pushing on something to gravity holding the Earth in orbit around the Sun, to cause it to change speed or direction. If there is no change in speed or direction, then no force is acting on it. This relates to mass in the following way. THE GREATER THE MASS, THE GREATER THE FORCE NEEDED TO MAKE THAT MASS CHANGE SPEED OR DIRECTION. Think of it like this; what takes more force to push up a hill, a car, or a bicycle. The bicycle has less mass and therefore requires less force to push it.
Force = Mass x Acceleration if an object is accelerating.
What is Motion?Kinetic Energy = 1/2 mass x velocity squared if it is moving at a constant pace, yet there is no force acting on the item in this scenario.
This will make the connection between force and mass more clear. Any action that exerts force on an object—from a person pushing something to gravity keeping the Earth in its orbit around the Sun—to change its speed or direction is referred to as force.
No force is acting on something if there is no change in its direction or speed. The following is how this relates to mass. The force required to cause a mass to change speed or direction increases with mass.
Therefore, Force = Mass x Acceleration if an object is accelerating.
