An ecosystem is a community of living organisms in conjunction with the nonliving components of their environment, interacting as a system. ... By feeding on plants and on one-another, animals play an important role in the movement of matter and energy through the system.
Answer;
Medulla.
When you run to catch a ball, your movements are planned and controlled from the Medulla.
Explanation;
The Medulla directly controls certain autonomic (involuntary) responses, such as heart rate, breathing, blood vessel dilation, swallowing, sneezing and vomiting.
It is located in the brain stem, anterior to the cerebellum.
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
∴
when v= 20
equating equation (1) and (2):
let multiply equation (1) by 100 and equation (2) by 1
4000V_{max} - 1000K_m = 4000
<u>4000V_{max} - 20 k_m = 8000 </u>
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
∴
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
Antibodies is the correct answer because they form bonds
Answer:
Explain, using the concept of genetic inheritance, how a complex like a mammal acquires it’s physical traits form both its parents?
Using the genetic inheritance, mammals acquire its physical traits from both parents due to phenotypic traits reflected from the dominance gene over the recessive gene. Phenotypic traits are inherited from parents but only appears physically in offspring
