Answer:
survival of fit individuals
Explanation:
I believe its survival of fit individuals because the animals with different horns are going to be able to find a mate or provide better depending on their horn and its kind of like natural selection in the sense those who have genetically better (??) horns are more likely to survive. Hope it helps but it might be a little bit of a confusing explanation.
Answer:
D. 2.5 × 10–4 M
Explanation:
Data given in the question are;
rate constant of 5.0 × 10–2 mol/L·s
[A]0 = 1.0 × 10–3 M
5 × 10–3 sec
It was mentioned that the reaction is a zero order reaction. One interesting charaacteristics about zero order reactio is that the rate of reaction is indepenedent on the concentrations of the reactants.
This means in zero order reactions, we have;
Rate = Rate constant
Rate = 5.0 × 10–2 mol/L·s
What is the concentration of B after 5 × 10–3 sec?
Concentration = Rate * Time
Concentration = 5.0 × 10–2 * 5 × 10–3
Concentration = 2.5 × 10–4 M
Correct option = D
Answer:
C₅H₈N₂O
Explanation:
The molecular formula denotes the various forms of atoms contained in a molecule at a particular fixed proportion.
The molecular ion M⁺ = 112.0499
and the exact mass values are given as follows:
C = 12.000
H = 1.0078
N = 14.003
O = 15.995
By assumption:
C = 12.000 × 5 = 60.0000
H = 1.0078 × 8 = 1.0078
N = 14.003 × 2 = 28.0060
<u>O = 15.995 × 1 = 15.9950 </u>
<u> = 112.0634 </u>
This is approximtely equal to 112.0499.
As such the Molecular formula for the compound = C₅H₈N₂O
Correct answer is <span>C. They have a full shell of valence electrons. </span>
Answer:
Tamoxifen is an irreversible, competitive inhibitor.
Explanation:
In order to binds to the active site of the estrogen receptor protein, tamoxifen have to compete with the other chemical compound, and inhibits the estrogen release, so it is a competitive inhibitor. Then, you said that when tamoxifen binds to the receptor, the protein is permanently deactivated, so it is also irreversible.
