Although the liver and the pancreas are not part of the digestive tract, they are important to the process of digestion because: a. Secretions they produce help to digest food b. They absorb nutrients into the bloodstream c. They eliminate wastes from the body d. All of the above
Answer:
The correct answer is - d. all of the above.
Explanation:
The liver and pancreas are not part of the digestive tract but they play a very major role in the process of digestion. The liver and pancreas both produce and secretes the enzymes and bile to breakdown the food into nutrients. Bile digests the fat while enzymes of the pancreas break down protein, carbohydrates, and fats.
The liver helps in absorbing the fats and some vitamins and minerals to the bloodstream from the nutrient from digested food. They also help in the removal of toxins and wastes from the digested food or the waste products of breaking down into nutrients through the feces or filtered from the blood by the kidneys.

O Solar energy seeped through the atmosphere,
O The eruption caused sunspot activity to increase.
O The volcano released a lot of sulfur dioxide and ash,
O Greenhouse gases caused the cooling of Earth's surface.
Answer: this is easy, i think
Explanation:
The volcano released a lot of sulfur dioxide and ash
According to question, "C" which is the volcano released a lot of sulfur dioxide and ash.
What is a volcano and what causes its eruption?When magma builds up in the magma chamber, it forces its way up to the surface and erupts, often causing volcanic eruptions.
In the ocean, volcanoes erupt along cracks that are opened in the ocean floor by the spreading of two plates called a mid-ocean ridge.
Thus, the volcano released a lot of sulfur dioxide and ash is correct.

The presence of many alleles for the trait to be expressed is called "multiple allelism," the presence of two alleles for the trait to be expressed is called "recessive," and the presence of a single allele for the trait to be expressed is called "dominant."
What are the dominance and multiple allelic patterns?There are different types of genes in animals and plants, such as some that have two copies of alleles, but if one is present, it can express itself in a heterozygous state, which is called a dominant gene because it can suppress the other allele, but some genes can only express themselves when there are many alleles, which are called multiple alleles.
Hence, the presence of many alleles for the trait to be expressed is called "multiple allelism," the presence of two alleles for the trait to be expressed is called "recessive," and the presence of a single allele for the trait to be expressed is called "dominant."

I need help with my science question Which molecules do cells need to release energy? Here is the choices.Claim 1: Cells need glucose to release energy. Claim 2: Cells need amino acids to release energy. Claim 3: Cells need oxygen to release energy. Claim 4: Cells need glucose AND amino acids to release energy. Claim 5: Cells need glucose AND oxygen to release energy Claim 6: ALL?
Answer:
Claim 5: Cells need glucose AND oxygen to release energy.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP). Therefore, the intermediary products are produced at the glycolysis and citric acid cycle stage through the breathing of oxygen used to obtain energy from the food ingested.
Hence, cells need glucose and oxygen to release energy.
The statement 'cells need glucose AND oxygen to release energy' is correct (Claim 5).
Cellular respiration is a series of metabolic reactions by which aerobic cells used oxygen and the energy stored in the chemical bonds of foods (e.g., glucose) to produce ATP.
Cellular respiration has three main stages: glycolysis, the citric acid cycle and oxidative phosphorylation.
During glycolysis, a molecule of glucose is used to create two molecules of pyruvate, which enter into the citric acid cycle.
Oxygen is the last acceptor of electrons in the electron transport chain of oxidative phosphorylation.
In conclusion, cells need glucose AND oxygen to release energy.
