An organism that creates its own food is called:
A) a producer
B)a consumer
C)a carnivore
D) a decomposer
Answer:
a
Explanation:
Answer:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria.

Describe the biome in which you currently live, or one in which you want to live, or have lived. What are the atmospheric conditions (wind pattern, humidity level, etc), solar intensity, and geographic/oceanographic features that have produced this unique ecosystem
Answer:
Southern Texas
Explanation:
The Wind pattern often is represented by the westerlies, which are the winds that flow in the northern latitude of the world. The humidity level in this zone varies from 10-20%, since we are in the desert we do not have much humidity, the solar intensity is high, often found in the 9-10 uv range, it is not advised to spend more than 10 minutes on direct sun without solar protection. We have the Rio Grande to the south and some spare mountains.

Any event or an occurrence that happens on its own without any human intervention is termed as a natural phenomena.
Natural phenomena harms the nature as well as life on earth.
Common examples of natural phenomena include thunder storms, earthquakes, landslides, volcanic eruptions, hurricane etc.
Some majestic natural phenomena include blood rain, Northern lights and luminous water in the world.
Natural phenomena can sometimes be destructive in nature and are therefore responsible for loss of lives and property.
It is almost impossible to predict the occurrence of any natural phenomena.
However, the negative outcome of natural phenomena can be managed with special disaster management operation
Thus, natural phenomena could only be observed and understood in science.

Two different enzymes catalyze the same reaction and both exhibit the same Vmax. When Enzyme A was run with a 40 uM substrate, the initial rate (Vo) was 10 uM/min, and when g it was run with a 4 mM substrate, the Vo was 20 uM/min. Estimate the approximate Vmax and Km of Enzyme A. When Enzyme B was run with 80 uM substrate, the initial rate (Vo) was 10 uM per minute. Estimate the Km of Enzyme B.
Answer:
a) k_m = 4.08 uM
V_{max} = 20.07 uM/min
b) k_m = 8.16 uM
Explanation:
Given that:
For Enzyme A:
the substrate concentration [S] = 40 uM
the initial velocity rate v = 10 uM/min
when it was 4mM, v = 20 uM/min
i.e.
at 4mM = 4000 uM;
Using Michealis -menten equation;
when v = 10
[tex]V = \dfrac{V_{max}[S]}{k_m+[S]}[/tex]
∴
[tex]10 = \dfrac{V_{max}\times 40}{k_m + 40}[/tex]
[tex]10 (k_m + 40) = V_{max}40[/tex]
[tex]40V_{max} -10k_m = 400 --- (1)[/tex]
when v= 20
[tex]20= \dfrac{V_{max}\times 4000}{k_m + 4000}[/tex]
[tex]20 (k_m + 4000) = V_{max}4000[/tex]
[tex]4000V_{max} -20k_m = 8000 --- (2)[/tex]
equating equation (1) and (2):
[tex]40V_{max} -10k_m = 400 --- (1)[/tex]
[tex]4000V_{max} -20k_m = 8000 --- (2)[/tex]
let multiply equation (1) by 100 and equation (2) by 1
4000V_{max} - 1000K_m = 4000
4000V_{max} - 20 k_m = 8000
0 -980k_m = 4000
k_m = 4000/-980
k_m = 4.08 uM
replacing the value of k_m into equation (1)
40{V_max } - 10(4.08) = 400
40{V_max } - 40.8 = 400
40{V_max } = 400 + 40.8
40{V_max } = 440.8
V_{max} = 440.8/40
V_{max} = 11.02 uM/min
b)
Since V_{max} of A ie equivalent to that of B; then:
V_{max} of B = 11.02 uM/min
Here;
[S] = 80 uM
V = 10 uM/min
∴
[tex]10 = \dfrac{11.02 \times 80}{k_m + 80 }[/tex]
10(k_m +80) = 881.6
10k_m = 881.6 - 800
10k_m = 81.6
k_m = 81.6/10
k_m = 8.16 uM

In a Nitrogen metabolism study, the following data were obtained over the test period:
Nitrogen consumed 175 grams
Total Fecal N 35 grams
Metabolic Fecal N 10 grams
Total Urinary N 80 grams
Endogenous Urinary N 10 grams
Calculate:
a. Apparent Nitrogen digestibility (%)
b. True Nitrogen digestibility (%)
c. Nitrogen Balance (g)
d. Apparent Nitrogen Retention (%)
Answer:
a. 80%
b. 86%
c. 60 g
d. 34.29%
Explanation:
From the given information:
The apparent nitrogen digestibility (AD) is the ratio of the difference between the consumed nitrogen and fecal nitrogen to the consumed nitrogen.
Mathematically:
[tex]AD = \dfrac{consumed \ nitrogen - fecal \ nitrogen }{consumed \ nitrogen }[/tex]
[tex]AD = \dfrac{175 -35 }{175}[/tex]
AD = 0.8
To percentage, the apparent Nitrogen digestibility = 80%
b. True Nitrogen digestibility is calculated by the formula:
[tex]=\dfrac{consumed \ nitrogen - (fecal \ nitrogen -metabolic \ fecal)}{consumed \ nitrogen}[/tex]
[tex]= \dfrac{175 -(35-10)}{175}[/tex]
[tex]= \dfrac{175 -25}{175}[/tex]
= 0.86
= 86%
c. Nitrogen Balance = consumed Nitrogen - Fecal nitrogen - total uninary
Nitrogen Balance = (175 - 35 - 80) grams
Nitrogen Balance = 60 g
d. Apparent Nitrogen Retention (ANR) is computed as follows:
[tex]ANR = \dfrac{(consumed \ nitrogen-fecal\ nitrogen - total \ uninary )}{nitrogen \consumed }\times 100\%[/tex]
[tex]ANR = \dfrac{(175-35- 80 )}{175 }\times 100\%[/tex]
[tex]ANR = \dfrac{(60 )}{175 }\times 100\%[/tex]
ANR = 34.29%
At her initial evaluation, Ms. Jones reports that she has lost 25 pounds over the past eight months despite an increase in her appetite. She complains of extreme fatigue, heart palpitations and irritability. Clinical observations reveal a protrusion of the eyeballs and hand tremors. You suspect that she might have:
a. hypothyroidism
b. diabetes mellitus
c. hypopituitarism
d. hyperthyroidism
Answer:
d. hyperthyroidism
Explanation:
Hyperthyroidism is a condition that occurs when the thyroid gland in our body secretes too much of the thyroxin hormone. Thyroid gland is a butterfly shaped gland that is located in our neck and it produces the hormone called thyroxin. Excess production of thyroxin leads to a condition named hyperthyroidism.
A person's metabolism increases when he or she is suffering from hyperthyroidism. One's weight is lost but the appetite increases. Other symptoms are extreme fatigue, irritability, heart palpitations, sweating and puffy eyes.
Thus in the context, Ms. Jones is suspect to have hyperthyroidism as she she is showing all the above symptoms.
