Yes, C4 is a process used by plants to survive in hot dry climates along with the CAM cycle. Hope this helps!
Answer:
The answers to both parts (1 and 2) are given below.
Explanation:
1. The calorimeter is similar to the bomb calorimeter in a way that both measure the changes in heat that occur as result of the chemical reaction taking place inside them. They are different in the sense that a bomb calorimeter provides an isolated system with constant volume and pressure, whereas a regular calorimeter allows pressure to equalize with the environment.
2. Carbohydrates are the molecules that break down and provides energy for cellular functions. Whereas, proteins are not meant for the production of energy but for the production of amino acids to function as structural units for protein synthesis. Simply, the breakdown of protein is for the synthesis of more proteins by providing several units of amino acids rather than the production of energy.
Answer:
a. Odds ratio = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning
Explanation:
For case study
Let 'a' represent the total population of people with melanomia = 696
Let 'b' represent the total number of people with melanomia exposed to indoor tanning = 1107 – 696 = 411 people
For control study
Let 'c' represent the total population = 1500
Let 'd' represent the total number of people not exposed to indoor tanning = 1500 - (0.428 * 1500)
= 1500 - 723
Total number of people not exposed to indoor tanning = 777 people
a. Odds ratio = (a/b) / (d/c) = (696/411) / (777/723)
= 1.69 / 1.07 = 1.58
b. Inasmuch the odds ratio is greater than 1, this means that higher odds of melanoma exist in people exposed to indoor tanning, than in those not exposed to indoor tanning.
Answer:
1. DDT (
Dichlorodiphenyltrichloroethane) with molecular formula; C14H9Cl5
2. Lead
Explanation:
1. DDT (Dichlorodiphenyltrichloroethane) is an example of compounds that biomagnifies in the biosphere. DDT is used as pesticides. When DDT is sprayed on plants to kill their pests, part of it is accumulated within the plants.
However, when primary consumers feeds on the affected plants, DDT is passed on to them and then to the secondary consumer in that sequence until it get to the top of the trophic level.
Effects of DDT have been seen in many organisms including birds and humans. The effects seen in humans is quite minimal to that of insects and birds. DDT causes lost of many insects and young birds. In humans, it causes vomiting, seizures etc.
2. Lead: it enters the biosphere by absorption and consumption means. Humans through the use of lead paint, smoking of cigarettes, use of cosmetics and combustion of coal accumulates lead in their bodies. Lead can't be synthesize by human, therefore it accumulates and biomagnify within their systems.
The effects of lead in human include; vomiting, stroke and abdominal pains. In tough scenario, it causes immune system deterioration and cardiovascular diseases.
Answer:
all functions
