Answer:
The circulatory and respiratory systems interact to transport carbon dioxide to the lungs, where it is expelled from the body.
Explanation:
Carbon dioxide produced by the cells and tissues during cellular respiration is removed from the body through the interaction of the circulatory and respiratory system. The medium of transport of carbon dioxide is the blood which carries to the lungs, where it is expelled from the body in ordernto maintain homeostasis in the body.
Carbon dioxide molecules are transported in the blood from body tissues to the lungs in three ways:
1. Dissolution directly into the blood - due to its greater solubility in blood than oxygen, carbon dioxide is dissolved in blood plasma. On reaching the lungs, it leaves the blood by diffusion and is then expelled out of the body.
2. Binding to hemoglobin - carbon dioxide binds reversibly with haemoglobin in the red blood cells to form a molecule called carbaminohemoglobin. When it reaches the lungs, the carbon dioxide freely dissociate from the hemoglobin and is expelled from the body.
3. Carried as a bicarbonate ion - the majority of carbon dioxide molecules are carried as part of the bicarbonate buffer system. In this system, carbon dioxide diffuses into the red blood cells. The enzyme carbonic anhydrase within the red blood cells quickly converts the carbon dioxide into carbonic acid (H2CO3) which then dissociates into bicarbonate and hydrogen ions. The bicarbonate ions leaves the red blood cells in exchange for chloride ions in the plasma. The bicarbonate ions then travel in plasma to the lungs, where they enter the red blood cells again. It combines with hydrogen ions from the haemoglobin to form carbonic acid. Carbonic anhydrase breaks carbonic acid down into water and carbon dioxide which is then expelled from the lungs.
The independent variable is the one that causes an effect on the dependent variable. In this case, the independent variable is <u>depth.</u> Different depths lead to a variation in temperature. 2)<em> depths</em>.
<h3>What are de dependent and independent variables?</h3>
- Independent variables are those modified or changed by the researcher to study how this change affects another variable and hence the results.
This variable is not affected by any other one but influences or causes a reaction in other variables.
- The dependent variable is the one influenced by the independent variable, and is affected by any change on this last one.
Its response might be either directly proportional or inversely proportional to the change in the independent variable.
Now let us answer the question.
The aim of the study was probably to analyze how temperature changed with depth.
So, according to this, depth influenced on the temperatureof water.
- The independent influencing variable is <u>depth</u>.
- The <u>dependent affected variable</u> is water temperature.
The correct option is 2. depths.

Students measured the temperature of the water at different depths in Lake Skywalker and found that the temperature varied. Which is the independent variable?
- Lake Skywalker
- depths
- temperature
- depths and temperature
Answer:
Because a food chain is very limited and only follows one path while a food web consists of many food chains made into one food web
Explanation:
The offspring that can be described by the genotype is
Gg while for the phenotype is
green pod color
The cross between GG and gg give a heterozygous offspring that Gg offspring. The offspring are have a green pod color since the green pod color is dominant over yellow pod color and therefore the offspring have a green pod color. The cross is as the punnet square below.
