Which describes a way in which phosphorus may enter into the phosphorus cycle?
Earthquakes release phosphorus.
Phosphorus is carried in the rain that was evaporated from lakes.
Human use of fertilizers release phosphorus into the groundwater.
Phosphorus is transpired from the leaves of plants.

Answers

Answer:

I think the correct answer from the choices listed above is option C. A way in which phosphorus may enter into the phosphorus cycle is that when human use of fertilizers release phosphorus into the groundwater. Hope this answers the question. Have a nice day.

Human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle. Therefore, the correct statement is option C.

What is the use of phosphorus?

Phosphorus is a nutrient needed by plants to grow, and it is added to soil in the form of fertilizers. When it rains, the phosphorus is washed away from the soil and carried into nearby rivers, lakes, and groundwater.

The phosphorus is then taken up by plants or become part of the sediment at the bottom of bodies of water.

Phosphorus can be transformed from there and recycled through the different parts of the phosphorus cycle, such as weathering, erosion, and sedimentation. Phosphorus can also be released from the decomposition of organic matter.

Therefore, human use of fertilizers releases phosphorus into the groundwater is a way in which phosphorus may enter into the phosphorus cycle.

Which statement best explains how sewage systems help fight the spread of disease?A.They carry antibiotics that kill pathogens in the air.B.They add chlorine to drinking water before it is transported to homes.C.They kill the animals that spread pathogenic bacteria.D.They carry human waste to treatment facilities away from cities.

Answers

Answer:

D.They carry human waste to treatment facilities away from cities.

Explanation:

Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.

Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.

name of a gland which act as mixed gland __
​

Answers

Answer:

PANCREATIC ISLETS

Explanation:

Since the pancreas has both endocrine and exocrine functions, it is therefore a mixed gland. Its endocrine secretions are the hormones insulin and glucagon

Pancreas is a heterocrine gland as it acts both as endocrine and exocrine gland. It secretes insulin hormone into blood and act as endocrine gland and when it secretes digestive enzymes and juice through pancreatic duct, it acts as exocrine gland.
Hence, pancreas is a mixed gland.
So, the correct answer is 'Pancreas'.

Answers

Answer:

The correct answer is - the amount of neurotransmitter released and the amount of calcium that enters the axon terminal.

Explanation:

The intensity of the signals or stimulus depends on the amount of the neurotransmitter such as acetylcholine, dopamine and the amount of calcium that enters the axon terminal.

A neurotransmitter is a chemical that carries, boost or balance a signal and send stimulus or signals throughout the body. When an action potential reaches the nerve terminal calcium channels open and enters.

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.

Answers

Answer: The color of the moths will become light.

Explanation:

Due to industrial exposure of smoke and dust the white color moths adapted a phenotypic trait of dark brown feather color which used to mimic the color of the tree trunk so the moth population was able to camouflage the predatory birds as these moths remain undetected. But due to reduction in pollution the tree trunk color regain its lighter color and these dark colored moths were detected by the predators so the dark color moth population decline and the white color of feather became the phenotypic trait passed in the next generation enabling the moth population to survive in reduce pollution conditions.

During the light reactions of photosynthesis, plants convert light energy into energy the plant can use. Where is the energy stored

Answers

Answer:

Photosynthesis is a process where plants and other organisms convert energy from the sun into a chemical energy that through cellular respiration can be later released in order to fuel the organism's metabolic activities.

The energy which is stored in the form of sugar is broken down into starch entering the mitochondria to produce energy. The energy is stored in the chemical bonds. To obtain the energy, organisms take energy-rich compounds such as glucose and breaks them down to release their energy. The organism traps the released energy and stores it in a form of adenosine triphosphate or ATP.

Explanation:

Workout the path taken by a carbon molecule as it moves from being part of the co2 in the air to being part of a starch molecule in a plant

Answers

Answer: The conversion of carbon dioxide occurs into glucose via photosynthesis.

Explanation:

The plants absorb carbon dioxide gas from the atmosphere. This is one of the reactants of the photosynthesis process. The water and carbon dioxide are the reactants of the photosynthesis process in the presence of sunlight the molecule of water splits into hydrogen and oxygen gas is liberated as byproduct and carbon dioxide becomes the product of the glucose. The monomers of glucose combine to form starch molecule which is stored as energy reserve in plants.

Answers

Answer:

you gotta put the small "b" for the female and all the the box will be "Bb"

The dominant allele (black fur) has alleles B and b for the recessive allele (white fur), so the offspring will all have bodies with black fur.

What is phenotype?

Phenotype is the physical appearance of characters which is the result of genes which express in the cell to give a particular trait in the diagram black is dominant over white so all the offspring show a black phenotype.

Male genotype: BB

Female genotype: bb

Cross: BB X bb

Gametes: B, B, b, b

All progeny will be black having genotype Bb, Bb, Bb, Bb.

The Cross is uploaded in the image below.

Genotype is the genetic appearance of the allele which shows the gene is responsible for a particular trait.

Therefore, the dominant allele (black fur) having allele B and b for the recessive allele is crossed, and all progeny will be black having genotype Bb, Bb, Bb, Bb.
