1. Although the state of Florida receives a lot of rainfall, about 61 percent of that water leaves the ground by evaporation and transpiration, and another 38 percent is ‘lost’ into the Atlantic Ocean & Gulf of Mexico, thus leaving only 1 percent of the rainfall water available for drinking and other human use.

2. Florida has a very vast underground water system, known as the Floridan aquifer system; for this reason, Florida is the source of drinking water to four other states. These states are South Carolina, Georgia, Alabama, and Mississippi. The Floridan underground water system is made up of the Upper and Lower Floridan aquifers.

3. Residents of the state of Florida wanted to get rid of the water in certain areas of the state because there was too many wetlands, they experienced frequent flooding which posed a great measure of difficulty in navigating the state.

4. One negative result of the changes made by people in order to get rid of the ‘excess’ water in Florida was groundwater depletion which has led to the drying up of wells, decrease in water level in streams and lakes, reducing quality of water and land subsidence.

5. One thing that has been done to try and improve those mistakes is Rainwater harvesting; a method which is often used to replenish ground water. Using the rainwater harvesting approach, an outlet pipe is connected from the rooftop and used to divert the rainwater to existing wells.

For the following question, match the key event of meiosis with the stages listed below. I. Prophase I V. Prophase II II. Metaph

Andrei [34K]

Answer:

VII. Anaphase II

Explanation:

During metaphase II, fibers of the spindle apparatus drive chromosomes to the cell equatorial plane, where they line up. Sister chromatids are holden together until they reach <u>Anaphase II</u><u>,</u> during which specialized enzymes break the bonds between chromatids and separate them. Each chromatid migrates to one of the poles. In telophase II, the new chromosomes are already in the corresponding poles, and the nuclear membrane forms again in each pole

Match the items: a. Heart b. Blood Vessels c. Capillaries d. Lungs e. Kidney 1. Regulates blood volume 2. Can decrease blood pH

Assoli18 [71]

<h2>Answer:</h2>

I believe the correct answer is:

a: 4

b: 3

c: 5

d: 2

e: 1

<h2>Explanation:</h2>

a: Heart - Can increase blood pressure by beating faster

b: Blood vessels - Can lower blood pressure by dilating

c: Capillaries - Exchange oxygen/carbon dioxide with tissues and alveoli

d: Lungs - Can decrease blood pH by increasing respiratory rate

e: Kidney - Regulates blood volume

<h2>Further Explanation:</h2><h3>a: Heart - Can increase blood pressure by beating faster</h3>

The heart is a fist sized organ in the center of the chest cavity and is lying on a wider base that is longer than its height and an apex that elongates to the left side of the chest. It functions to circulate and distribute blood to different regions of the body using blood vessels. The heart has several baroreceptors that sense a decrease in the volume of blood or pressure and it adjusts by beating faster. It also is controlled autonomously by the autonomic nervous system that will also adjust its pace when it recieves signals to do so in the case of low bloo pressure or in cases of high demand such as in a scary activity.

<h3>b: Blood vessels - Can lower blood pressure by dilating</h3>

Blood vessels are hollow tissues that have elastic walls which control the size of its luen. They function to supply blood to tissues in every region of the body. In cases when the blood pressure is too high, it recieves signals from the brain to its muscles that have beta cholinergic receptors that instruct it to dilate/relax so that blood will have inimal resistance hence less pressure as it is passing through it.

<h3>c: Capillaries - Exchange oxygen/carbon dioxide with tissues and alveoli</h3>

These are the smallest of all blood vessels and they are distributed in every region of the body. They have elastic and permeable walls which allow red blood cells carrying oxygen to move into the tissues they are moving through and also nutrients while at the same time they pick up waste and red cells that have collected carbon dioxide from the tissues. They also are densely populated in alveoli to perform the same function during respiration.

<h3>d: Lungs - Can decrease blood pH by increasing respiratory rate</h3>

CO2 is acidic while O2 is a Lewis base. In cases where the blood has a pH that is more basic than the required pH of 7.3, the body either undergoes a metabolic compensation through retaining more bases such as chloride ions. In case there is a problem with the kidney, the body triggers the respiratory system to increase the respiratory rate so that oxygen is not exposed to the alveoli for a longer time to be absored fully hence it will be in blood at a lesser percentage compared to acidic CO2 which will have a higher percentage making the blood more acidic. To understand how these work using a diagram, look at the table below for arterial blood gas.

<h3>e: Kidney - Regulates blood volume</h3>

The kidney filters blood to remove and balance fluids. In the afferent arteriole that supplies the kidney with the blood to be ultrafiltrated there are specific baroreceptrs that sense a rise or a fall in blood volume. The kidney if the volume is low will retain more ions so that it can draw water back into the vasa recta and increasing the blood volume. If the volume is too high, it will lose more ions into urine and so water will be lost as part of urination until the volume stabilizes to the correct volume.
