Explanation:
Energy is released from ATP when every phosphate bond is broken. the last phosphate bond is broken. all three phosphate bonds are formed. the last phosphate bond is formed.
Answer:
the last phosphate bond is broken
Explanation:
ATP, is a chemical molecule with the name, Adenosine triphosphate. It is the energy currency of a living cell usd to drive many cellular processes in the body. ATP is produced during the process of cellular respiration.
Adenosine triphosphate (ATP) has an Adenosine molecule (Adenine base and a ribose sugar) and three phosphate groups. However, the energy in ATP is harnessed for utilization when the bond that binds the third phosphate group is broken.
The breaking of the last phosphate bond releases a phosphate group and an Adenosine diphosphate (ADP) molecule.

When people have their gallbladders removed, their bodies no longer have a place to store bile, and the bile flows from the liver continuously. What effect might this have on their ability to digest fats?
A. There will be very little change since bile will still be present to emulsify fats.
B. Fats will be emulsified more efficiently with the constant flow of digestive enzymes.
C. It will be unlikely that they will be able to emulsify and digest fats.
D. Only small amounts of fats will get digested since high concentrations of bile enzymes are needed for efficient digestion.
Answer:
A. There will be very little change since bile will still be present to emulsify fats.
Explanation:
The gallbladder is a pear-shaped storage sac present in the alimentary canal of humans and functions to store excess bile in between meals. The bile is a greenish-yellow substance composed of different substances like salts, bile pigments, cholesterol etc. The bile is produced in the liver and aids in the digestion of fats.
The gallbladder serves as an intermediary between the organ of bile production (liver) and its destination (intestine). According to the question, once the gallbladder is removed, there is no longer a place to store bile. However, bile will still be produced by the liver and released directly into the intestine instead.
Hence, the bile will still be present to perform its function of emulsifying fats with little changes in the way it is released into the intestine. Note that, the gallbladder only regulates the speed at which the bile is released into the intestine.

Which of the these do plants NOT obtain using Active transport?
A. Phosphorus
B. Carbon dioxide
C. Potassium
D. Nitrogen
Active transport is the system that requires energy to transport the macro and micronutrients. Carbon dioxide is not transported through active transport. Thus, option B is correct.
What is active transport?Active transport is the mechanism to transport the molecules and the ions from regions of low concentration to higher concentration with the help of the energy as the movement are opposite the gradient.
The macronutrients like phosphorus, nitrogen, and potassium are transported with the help of the transporter molecules across the membrane and utilize ATP. While carbon dioxide diffuses directly and requires no energy.
Therefore, carbon dioxide is transported by passive transport.

HELP!! Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?
Answer:
The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
Decrease in available resources lead to decrease in carrying capacity of an environment for a population. The rainforest's bee population is a limiting factor for orchid population, decrease in bee population will lead to decrease in orchid population.
Hence, the carrying capacity will decrease due to decrease in limiting factor as the number of orchids that can be sustained by the environment would decreases.

Which best explains a primary reason for the inability of life to exist in Earth’s early atmosphere? There was insufficient energy from material collisions to change their density. High temperatures during Precambrian time caused surface water evaporation. Volcanic eruptions and comet collisions added different gases to the atmosphere. Available oxygen was used to help create an ozone layer within Earth’s atmosphere.
Answer:
c
Explanation:
on edge
The sentence that best explains the primary reason for the inability of life to exist in Earth’s early atmosphere is " Volcanic eruptions and comet collisions added different gases to the atmosphere".
During the early years of the Earth volcanic eruptions were much more common than they are today. When these volcanoes erupted, they spewed many gases into the atmosphere, including:
Carbon dioxideWater vaporNitrogenHydrogenwhich was directly responsible for the composition of the early atmosphere.
Due to these gases being released into the atmosphere by Volcanic eruptions, causing a severe lack of oxygen, life on Earth was almost unsustainable. It was not until solar radiation and photosynthesis produced oxygen that life became sustainable.

There are a few different steps we can take to protect the ozone layer. As you know, the ozone layer is the layer that protects us from the sun’s powerful UV rays and it also protects us from other harmful things roaming in space. The first thing we can do to protect the ozone layer is reduce the use of natural gases. The gases produced from the natural gases had torn holes in the ozone layer. A way to prevent emissions of hazardous gases Is to switch to renewable energy. Renewable energy is not only easier to access and replace, solar panels and wind energy dont give off harsh and hazardous gases that mess with the ozone layer and the climate.

What is the function of the nucleus?
O A. To store the cell's genetic material
OB. To combine amino acids to make proteins
O C. To control what enters and leaves the cell
D. To provide the cell with energy
Answer:
A. To store the cell's genetic material
Explanation:
The nucleus stores DNA which is the genetic material.
A chromosome’s structure is what it is made of and how it is organized. Its function is what it does. How does knowing about the structure and function of chromosomes help to explain variation in sexually reproducing organisms?
Answer:
Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6.5 feet) in length. The compactness of chromosomes plays an important role in helping to organize genetic material during cell division and enabling it to fit inside structures such as the nucleus of a cell, the average diameter of which is about 5 to 10 μm (1 μm = 0.00l mm, or 0.000039 inch), or the polygonal head of a virus particle, which may be in the range of just 20 to 30 nm in diameter.
