Answer:
In endothermic reactions, more energy is absorbed when the bonds in the reactants are broken than is released when new bonds are formed in the products. Endothermic reactions are accompanied by a decrease in temperature of the reaction mixture.

Explanation:
What step occurs in the cristae?
The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.
What is mitochondria?Mitochondria are cell organelles that generate the maximum of the chemical energy required to power the cell's biochemical reactions (mitochondrion, singular).
The mitochondrial energy is stored in a small molecule known as adenosine triphosphate (ATP).
The crista of mitochondria, formed by invaginations of the inner mitochondrial membrane, is where oxidative phosphorylation occurs.
Thus, the process name is oxidative phosphorylation.

Which statement is an accurate description of genes? SC.912.L.16.3
Proteins are made of genes and code for DNA
Genes are made of proteins that code for nitrogen bases
DNA is made of carbohydrates that code for genes
Genes are made of DNA and code for proteins
Answer:
B
Explanation:
Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.
What are genes made up of?Genes are made of DNA and code for proteins.This is because genes contain the genetic information needed for expression of characteristics in a living organisms. Therefore, genes contain DNA which is the genetic material. Genes are housed in chromosomes located in the loci.
DNA molecule forms a chromosome, and part of the same DNA molecule produce the genes on that is found in that chromosome. The information that is present in each gene codes the production of proteins and alsothe synthesis of RNA.
Genes are the molecules responsible for containing the genetic information that determines specific characteristics or features of an individual. Genes are housed in chromosomes, in specific locations called locus.
A DNA molecule forms a chromosome, and fragments of that same molecule form the genes on that chromosome. The information contained in each gene codes the synthesis of proteins, as well as the synthesis of RNA.
Therefore, Genes are made of proteins that code for nitrogen bases. This is the description of genes. Thus, option C is correct.

Calculate the molarity of 0.75 L of a solution containing 0.83 g of dissolved KCI. A 0.015 M B 0.75 M C 1.1 M D 6.2
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M

Which of the following statements about muscles and the muscular
system is true?
O The three types of muscle tissue are skeletal muscle, smooth muscle, and involuntary
muscle.
O Muscles always work independently to move parts of the body.
All muscle action is voluntary, or able to be consciously controlled.
OSmooth muscle moves food through the digestive system.
Smooth muscle moves food to the digestive system, which is the true statement about the muscle and muscular systems. Hence, the fourth option is the correct answer.
What are different types of muscles?In the human body, there are three types of muscles: skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle is called voluntary muscle.
Voluntary muscles move in response to commands. Examples are the muscles of the hand and legs. They move when an organism wants to move. Cardiac muscle and smooth muscle are involuntary in nature.
The contraction and relaxation of involuntary muscles don't depend on the individual's wish. Smooth muscles are present in the internal organs such as the intestine, stomach, etc. When food reaches the stomach, the stomach muscle contracts and relaxes to digest the food. The cardiac muscle is present in the heart. It always works.
Hence, option 4 is the correct answer, as smooth muscle moves food through the digestive system.

Why is it important for the cells produced in meiosis to be haploid?
Answer:
The overall process of meiosis produces four daughter cells from one single parent cell. Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell. ... Unlike in mitosis, the daughter cells produced during meiosis are genetically diverse.
Answer:
A.) Because bacteria only need half the DNA to survive and they are the only ones that do meiosis.

what impact do you think the flooding river will have on the surrounding landscape
Explanation:
erosion
lossing of fine sidement
Floods Cause Sedimentation and Erosion riverbanks and forcing them to collapse, for instance, floodwater also can change the terrain. Floodwater suspends silt within the water as it drags debris from the eroding banks, which may deteriorate the water's quality and cause toxic algae blooms.
What about floods?Floods, the foremost common sort of natural disaster, happen when an more than water submerges normally dry ground.Floods are typically caused by lengthy, intense rain, rapid snowmelt, storm surges from tropical cyclones, or tsunamis in coastal areas.Flooding often happens when heavy rain falls for an extended period of your time over a short period of time, or when a river or stream overflows due to an ice or debris trap. Flooding also can happen when a levee or other water-controlling structure, sort of a dam, fails. Loss of human life is one among the negative outcomes of flooding. Infrastructure and property destruction. Dangers of landslides, erosion, and road closures. Damage of crops and loss of livestock.The most vulnerable areas to flooding are river floodplains and coastal regions, although flooding can also happen in places with exceptionally lengthy periods of heavy rain. These have the potential to harm coastal food supplies, limit coastal production, and deteriorate aquatic habitats.Learn more about floods here:

The heart beats and organs are formed during the first trimester.
Teeth and fur develop during the second trimester.
Three-quarters of all growth occurs during the third trimester.
Answer:
Three-Quarters of all growth occurs during the third trimester.
Explanation:
D is the only option that has anything to do with the last trimester which is what the question was asking about. Furthermore, because so much growth is occurring during this time the cow will need more food to support this growth. So, D is the best option.

Explain why a coyote might be grouped into Level 3 in one food web and Level 4 in another.
Answer:
This situation might happen depending on the ecosystem that it takes place in.
Explanation:
For example, in one ecosystem, where there are no serious predators trying to get the coyotes, they could be in a higher level because there is no immediate danger to them. However, in another ecosystem where there are predators trying to hunt them, they would be in a lower level because there, they are not at the top of the food web. Basically, it all depends on the ecosystem.
