Answer: The dead plants form the organic part of the soil.  This is because when plants die off they become dirt and mulch which is good for the plants. This is why people make a big deal out of compost. It is because it is healthy and organic for plants.

<u>Answer</u>:

<em>Dead plants form the organic portion of the soil. </em>

<u>Explanation</u>:

<em>Plant bodies and animal bodies are rich in carbon compounds and when they die their body remains will contain these compounds.</em> Soil contains various microbes that act on the dead remains and break down the organic compounds within the remains.

The decomposition process releases <em>carbon, nitrogen, phosphorous etc that make up the organic compounds. </em>

Decomposition of plant bodies is termed as composting. Composting releases carbon in greater amounts into the soil. The <em>inorganic substances released after decomposition can be used by plants and other autotrophs for nutrition. </em>

State the major processes of the urinary system and describe the activity of each process.
Dennis_Churaev [7]

Answer:

The urinary system removes excess substances and waste products from the metabolism from the body through the urine, contributing to the maintenance of homeostasis, the chemical composition of the internal environment. Urine is produced in the kidneys, passes through the ureters to the bladder, where it is stored and is released into the exterior through the urethra.

The kidneys perform the main work of the urinary system comparing with the other parts of the system, acting primarily as passageways and storage areas. With the filtration of blood and the formation of urine, the kidneys contribute to homeostasis of body fluids in a number of ways, such as: Regulation of the ionic composition of blood; Maintenance of blood osmolarity; Regulation of blood volume; Blood pressure regulation; PH regulation of blood; Hormone release; Regulation of blood glucose level; Waste excretion and toxic substances.

Ureters - They are two tubes that carry urine from the kidneys to the bladder. The ureters are capable of performing rhythmic contractions called peristalsis. Urine moves along the ureters in response to gravity and peristalsis.

Bladder - The urinary bladder acts as a temporary reservoir for urine storage. It is a hollow, elastic muscular organ that in men is directly anterior to the rectum and in women, is located in front of the vagina and below the uterus.

Urethra - is a tube that conducts urine from the bladder to the outside, being lined with mucosa that contains a large amount of mucus-secreting glands. The urethra opens outwards through the outer ostium of the urethra.

Semenov [28]
Hey there!

I think you mean the Finches. Each Finch has a beak that is very similar to other beaks on the other islands. This shows that they are related. Their beaks change so that they can live better in their environment. They all had a common ancestor.

I hope this helps!
