Which two macromolecules contain nitrogen? A. Proteins and nucleic acids
B. lipids and vitamins
C. Carbohydrates and proteins
D. Carbohydrates and lipids
Answer: Option A) proteins and nucleic acids
Proteins are made up of multiple amino acids with positively charged amino groups in their side chains. These amino groups (NH2) have nitrogen atoms.
Nucleic acids also have nitrogen atoms in the nitrogenous bases present in their structure. For example, DNA and RNA have adenine molecules with two nitrogen atoms in their structure.
I'll do my best and give you five stars if you answer this question correctly. Why does a cell have to grow and copy its DNA before cell division begins? Justify your answer with more than one answer
Answer: Because two or more daughter cells are formed and each must contain the parent chromosome
During the healthy development of a living organism, cells undergo cell division (mitosis or meiosis). Before dividing, during the resting phase (interphase), the cell makes two copies of all its organelles, including the nucleus, so it would make two daughter cells (in mitosis) or four daughter cells (in meiosis).
Are coyotes dying?
Where are coastal areas unlikely to host a kelp forest ecosystem? Why do you think this might be?
When algae thrive in clear water where sunlight can penetrate because these "plants" participate in photosynthesis.
What is a forest ecosystem?
Kelp forests thrive in both peaceful coastal and polar regions. They are rare in the tropics because the seawater is warmer at these lower latitudes. Kelps do well in seawater with a temperature between 5 and 20 °C. This is because cold water is rich in nutrients and has a higher concentration of dissolved oxygen than warm water. The algae in the complex thrive in clear water that sunlight can penetrate because these "plants" are photosynthetic.
More information about the forest ecosystem can be found here:

What molecules make up most of the cell membrane bilayer? A. Phospholipids
C. Carbohydrate chain
Answer: A). Phospholipid
Explanation: The cell membrane is a phospholipid bilayer. Phospholipids consist of two components: the fatty acid chain and the phosphate head group. The phosphate groups of phospholipids are polar while the fatty acid chains are nonpolar. The non-polar fatty acyl chains face each other and form a bilayer, while the phosphate head group faces outward and interacts with the environment. The cell membrane contains other components such as proteins and carbohydrate chains, but in smaller amounts, so phospholipids are the main component of the cell membrane.

How does carbon exit an animal? ›
For example, animals exhale carbon dioxide when they breathe and release carbon dioxide when they decompose. The oceans also exchange carbon with the atmosphere by absorbing carbon, which then sinks as it cools. In addition, carbon is stored in rocks and other geological deposits.How does carbon enter and leave animals? ›
Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too. Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground.Where does carbon go after animals? ›
When the animals die, they decompose, and their remains become sediment, trapping the stored carbon in layers that eventually turn into rock or minerals. Some of this sediment might form fossil fuels, such as coal, oil, or natural gas, which release carbon back into the atmosphere when the fuel is burned.How do animals decrease carbon in the atmosphere? ›
Mammals and their interactions increase the amount of carbon stored in soils and trees. When carbon is stored, this helps to slow down climate change, because that carbon is removed from the atmosphere. But animal populations worldwide are decreasing.How does carbon exit? ›
Carbon is released back into the atmosphere when organisms die, volcanoes erupt, fires blaze, fossil fuels are burned, and through a variety of other mechanisms.Do animals breathe out carbon? ›
All animals breathe to obtain oxygen for their bodies and to expel carbon dioxide, but there are many different ways of breathing.How do animals get rid of the carbon dioxide? ›
Ask: What gases do animals breathe in and breathe out? What gases do plants take in and release through photosynthesis? (Answer: Animals' bodies use oxygen and produce carbon dioxide; breathing out, or exhaling, releases carbon dioxide.How does carbon return from animals into the water? ›
animals (organisms) decay or by the waste products from animals. carbon from dissolved carbon dioxide in the water. This CO2 is released into the water by aquatic animals due to cellular respiration.How does carbon leave and enter our bodies? ›
In the human body, carbon dioxide is formed intracellularly as a byproduct of metabolism. CO2 is transported in the bloodstream to the lungs where it is ultimately removed from the body through exhalation.Do animals release carbon through photosynthesis? ›
Animals, during respiration, take in oxygen and release carbon dioxide gas. Plants, on the other hand, utilize this carbon dioxide gas in the process of photosynthesis to produce food and release oxygen in the atmosphere.
What process removes carbon from the atmosphere? ›
Photosynthesis removes CO2 from the atmosphere and replaces it with O2. Respiration takes O2 from the atmosphere and replaces it with CO2.Where do animals get their carbon atoms from? ›
Animals get carbon by eating plants or by eating other animals. Different products produce differing amounts of greenhouse gases. Common greenhouse gases include carbon dioxide, carbon monoxide and methane.How do animals take in oxygen and get rid of carbon dioxide? ›
Oxygenated air, taken in during inhalation, diffuses across the surface of the lungs into the bloodstream, and carbon dioxide diffuses from the blood into the lungs and expelled during exhalation.What body system is involved with removing carbon dioxide from animals? ›
The Respiratory System
This is how the body gets rid of carbon dioxide. The blood collects carbon dioxide from all over the body and carries it back to the air in the alveoli.
Whales | Deep sea climate solutions
As Earth's largest mammal, whales absorb an average of 33 tons of carbon each throughout their lifetimes. When they die, their carcasses fall to the bottom of the ocean and remain there for centuries, keeping that stored carbon out of the atmosphere.
Some carbon dioxide makes its way out of the atmosphere through the carbon cycle, but we are emitting so much that the amount of carbon dioxide in the air keeps increasing.What happens when carbon is released? ›
Carbon dioxide molecules provide the initial greenhouse heating needed to maintain water vapor concentrations. When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapor drops.Do animals let out carbon dioxide? ›
Animals and plants need oxygen. When an animal breathes, it takes in oxygen gas and releases carbon dioxide gas into the atmosphere. This carbon dioxide is a waste product produced by the animal's cells during cellular respiration.Do all animals release carbon dioxide? ›
It is produced by almost all living organisms (both plant and animal). It is given off, (exhaled) into the air every time we breathe. Even organisms without lungs or gills release carbon dioxide into the environment.Do dead animals emit carbon? ›
In addition, dead animals rotting in the environment also emit greenhouse gases such as Nitrous oxide (N2O), Carbon dioxide (CO2) or Methane (CH4) into the atmosphere (Dalva et al., 2015, Sakata et al., 1980, Zeng, 2015).
How do animals get rid of the carbon dioxide quizlet? ›
Carbon cycle: -Plants take in CO2 by photosynthesis. -Animals eat the plants. -Animals breath out carbon dioxide after the plants give off oxygen that was converted from the carbon dioxide.What gas do animals breathe out? ›
Animals breathe, oxygen and give out carbon dioxide.How does carbon get trapped in ocean by ocean animals? ›
Carbon gets incorporated into marine organisms as organic matter or structural calcium carbonate. When organisms die, their dead cells, shells and other parts sink into deep water. Decay releases carbon dioxide into this deep water.
As her cells create energy from glucose, they produce waste products such as carbon dioxide, which she exhales. During respiration, glucose plus oxygen yield carbon dioxide, water, and energy. This way of generating energy from glucose in animals, mirrors what occurs during photosynthesis in plants.Which part do animals use to breathe out carbon dioxide? ›
-Here oxygen is diffused into the cells from the blood capillaries and simultaneously carbon dioxide from the cells moves into the blood through which it is taken to the lungs to get released into the atmosphere. -The oxygen in cells is used to burn food to get energy released as ATP.How do animals obtain oxygen? ›
While humans and terrestrial animals breathe oxygen from the air, aquatic animals use oxygen that is dissolved in water. An aquatic animal breathes by absorbing free oxygen into its blood through its gills or directly through its body surface.What animal absorbs the most carbon dioxide? ›
Whales accumulate carbon in their bodies during their long lives. When they die, they sink to the bottom of the ocean; each great whale sequesters 33 tons of CO2 on average, taking that carbon out of the atmosphere for centuries. A tree, meanwhile, absorbs only up to 48 pounds of CO2 a year.What happens to the carbon when animals eat? ›
When an animal eats a plant, carbon from the plant becomes part of the fats and proteins in the animal. Decomposers and some animals, called detrivores , feed on waste material from animals, and the remains of dead animals and plants. The carbon then becomes part of these organisms.What absorbs the most carbon? ›
Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a huge role in the world's carbon cycle - absorbing about as much carbon as all the plants and trees on land combined.Do animals leave a carbon footprint? ›
And the production of pet food emits huge amounts of planet-warming gases. According to a 2017 study, feeding dogs and cats creates the equivalent of around 64 million tons of carbon dioxide in the US each year. That's roughly the same impact as 13.6 million cars on the road.
What are two ways carbon returns from animals? ›
Animals that eat plants digest the sugar molecules to get energy for their bodies. Respiration, excretion, and decomposition release the carbon back into the atmosphere or soil, continuing the cycle.How is carbon returned back to the soil after an animal or a plant dies? ›
Carbon is returned to an inorganic state in a number of ways. As an animal breathes (respires), it exhales carbon dioxide, returning it back to the atmosphere. When an animal or plant dies, it is broken down by bacteria and fungi and again the carbon is released (this process is called decomposition).What happens to the carbon dioxide released by aquatic animals? ›
All aquatic organisms release this gas into the water. Some of it bubbles to the surface, some of it dissolves (mixes in) with the water, but most of the carbon dioxide found in the water is produced by organisms (bacteria mostly) that carry on decomposition of dead material.What is the source of carbon for animals? ›
Animals release water as a waste product from the oxygen respiration. Animals, like all heterotrophs, use organic materials as their sole source of carbon.Is animals give off carbon dioxide? ›
Animals breathe, oxygen and give out carbon dioxide.Does animal waste produce carbon dioxide? ›
About 44 percent of livestock emissions are in the form of methane (CH4). The remaining part is almost equally shared between Nitrous Oxide (N2O, 29 percent) and Carbon Dioxide (CO2, 27 percent).
