A 20.0 gram sample of a certain radioisotope decays over a
period of 19.2 hours. After that time, only 2.50 g of the isotope
remains. Calculate the half-life.
quantity of the substance remaining = initial quantity of the substance * (.5)^(time elapsed/half life of the substance)
2.50 = 20 * (.5)^(19.2/x)
The half-life period of the given sample of the radioisotope is equal to 6.41 hours.
What is the half-life period?The half-life of a radioactive substance is defined as the time that is required to reduce the original quantity of a radioactive element to half after decay.
Half-life of a radioactive element is the characteristic of the element and does not depend upon the initial amount of the radioactive substance.
Given, the original amount of the radioisotope, N₀ = 20.0 g
The remaining amount of the radioisotope, N = 2.50 g
The time for which decay occurs, t = 19.2 hours
Consider that k is the rate constant of the decay of radioisotope,
[tex]k =\frac{2.303}{t} \times log \frac{N_0}{N}[/tex]
[tex]k =\frac{2.303}{19.2} log \frac{20}{2.50}[/tex]
k = 0.108 hr⁻¹
The half-life time of radioisotope can be calculated from the below mentioned formula:
[tex]t_{\frac{1}{2}} =\frac{0.693}{k}[/tex]
[tex]t_{\frac{1}{2}} =\frac{0.693}{0.108}[/tex]
[tex]t_{\frac{1}{2}} =6.41 hrs[/tex]
Therefore, the half-life period of the given sample of the radioisotope will be to 6.41 hours.

B. It removes essentials nutrients from organisms’ habitats.
C. It prevents animals from catching prey or escaping predators.
D. It increases the body temperatures of organisms to harmful levels.
C. It prevents animals from catching prey or escaping predators is the correct option.
What is noise pollution?Noise pollution also understood as environmental noise or sound pollution, exists as the propagation of noise with ranging consequences on the activity of human or animal life, most of them detrimental to a degree. The source of outdoor noise worldwide exists mainly caused by machines, transport, and propagation techniques.
Noise pollution also understood as environmental noise exists as the propagation of potentially “damaging” sounds via the environment. The impacts of noise pollution tend to be seen as a nuisance rather than an environmental concern for decades.
Noise pollution harm wildlife by preventing animals from catching prey or escaping predators.Due to noise pollution the prey organisms do not come out from their habitat. It becomes difficult for the predator to catch their prey if they do not comes out. Also prey organisms gets frightened and fails to escape from their predators.

Select the events that are a consequence of activating mutations in the ras gene. The ras proto-oncogene is converted into an oncogene. Specific transcription factors are activated by phosphorylation. The signal transduction cascade of the MAP kinases is repressed. Abnormally rapid cell growth and proliferation is induced. Malignant transformation of normal cells is inhibited.
Answer:
- The ras proto-oncogene is converted into an oncogene
- Specific transcription factors are activated by phosphorylation
- Abnormally rapid cell growth and proliferation is induced
Explanation:
The Ras genes are proto-oncogenes, i.e., genes with oncogenic potential that may induce cancer. These genes (Ras) encode GTPase proteins involved in transducing survival and growth signals. When Ras genes suffer mutations, the resulting Ras proteins may remain in an active state that prevents the hydrolysis of GTP, thereby the Ras pathway remains constitutively activated. In consequence, mutated Ras genes function as oncogenes by constitutively activating MAP kinases which in turn activate transcription factors that control the expression of target genes involved in critical cellular processes and whose expression is associated with cancer-specific events (eg., increased angiogenesis, increased cell proliferation, reduced apoptosis, etc).

Which description accurately describes the cell membrane?
a. a single permeable layer of phospholipids that have hydrophobic heads and hydrophilic tails
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
c. a single permeable layer of phospholipids that have hydrophilic heads and hydrophobic tails
d. a semi-permeable double layer of phospholipids that have hydrophobic heads and hydrophilic tails
e. a barrier of polypeptides that prevents molecules from entering or leaving the cell
Answer:
b. a semi-permeable double layer of phospholipids that have hydrophilic heads and hydrophobic tails
Explanation:
B is correct as the cell membrane is selectively semi-permeable. It is selectively semi-permeable because this quality allows it to control what can and can't enter the cell, and how it does so.
The cell membrane also has a phospholipid bi-layer comprised of a double layer of phospholipids which have hydrophilic head and hydrophobic tails. This is because the heads are made of phosphate and are polar and are therefore attracted to water (hydrophilic), while the tails are made of lipids (i.e. fats, oils) which do not mix with water and are therefore hydrophobic.
The properties of each phospholipid is also why they form the double layer structure, the hydrophilic heads naturally face outwards into the water and protect the hydrophobic tails on the inside.
