Which organelle packages and distributes proteins that are received from the endoplasmic reticulum?

2 answers:

8 0

<span>The Golgi-Apparatus is the organelle that packages and distributes proteins that are received from the endoplasmic reticulum. It can be found in most eukaryotic cells, and was named after the Italian scientist Camillo Golgi who identified it in 1897. It is an important organelle whose function is also to process proteins for secretion, among other things. </span>

T or F: Addiction is a condition of compulsive drug seeking and use, even with negative

valkas [14]

Addiction is a condition of compulsive drug seeking and use, even with negative consequences is a <u>true</u> statement.

Explanation:

Addiction to drugs is a chronic and a relapsing condition or disorder which results in compulsory drug seeking behavior and its continuous use despite knowing about or having negative consequences it can cause to the brain and the body systems.

This is both a medical and a mental illness due to repeatedly misusing drugs or other substances and a severe form of a spectrum of substance abuse disorders.

Addiction is classified under substance use disorder and is categorized as mild, moderate or severe according to the symptoms. The symptoms or the negative consequences of addiction are generally grouped as impaired control, risky use, social impairment, pharmacological criteria for drug tolerance or withdrawal.

Peat is a mixture of partially decomposed plant and animal material found in waterlogged, acidic, anaerobic environments. people

Verizon [17]

because the total time for restoration is lengthy, peat can be considered a fossil fuel. The correct option is B.

<h3>What exactly are fossil fuels?</h3>

Fossil fuels are fuels derived from the remains of dead plants and animals that decomposed over time under intense heat and pressure.

Because their replenishment time is longer than a human lifetime, fossil fuels are non-renewable energy sources.

Some examples of fossil fuels are petroleum, coal, etc.

The missing options of the question are:

peat is a fossil fuel because rewetting it takes only 3-5 years.
peat is a fossil fuel because the total time for restoration is lengthy.
peat is not a fossil fuel because it has biologic origins, making it a biofuel.
peat is not a fossil fuel because humans can promote the replenishment of peat.

The restoration process of peat takes a long time of more than 100 years. As a result, because the total time for restoration is lengthy, peat can be considered a fossil fuel.

Thus, the correct option is B.

Describe the amount of respiratory membrane surface area in healthy adults:

kirill115 [55]

Answer: The respiration is a process, which occurs in all living organisms. In respiration a food or substrate present in the body is broken down into components in the present or absence of oxygen.

Explanation:

The respiratory membrane surface area is marked by the surface acquired by the small bronchi that branches into small bronchioles. Further the bronchioles extent to the alveoli for respiratory gas exchange.

In case of a human adult there are 300 million bronchi which cover an area of 180m². So, the total amount of respiratory surface area in healthy adult is 180m².

22. A plant geneticist is investigating the inheritance of genes for bitter taste (Su) and explosive rind (e) in watermelon (Cit

mylen [45]

Answer:

See the answer below

Explanation:

Using the formula for calculating Chi square ( $X^2$ ):

$X^2$ = $\frac{(O - E)^2}{E}$ where O = observed frequency and E = expected frequency.

The observed frequencies for the four phenotypes are 88, 62, 62, and 81 respectively.

For the expected frequency, the phenotypes are supposed to assort in 9:3:3:1 according to Mendel ratio.

Hence, expected frequencies are calculated as:

phenotype (1) = 9/16 x 293 = 164.81

phenotype (2) = 3/16 x 293 = 54.94

phenotype (3) = 3/16 x 293 = 54.94

phenotype (4) = 1/16 x 293 = 18.31

The $X^2$ is calculated thus:

Phenotype O E $X^2$

1 88 164.81 $\frac{(88 - 164.81)^2}{164.81}$ = 35.80

2 62 54.94 $\frac{(62 - 54.94)^2}{54.94}$ = 0.91

3 62 54.94 $\frac{(62 - 54.94)^2}{54.94}$ = 0.91

4 81 18.31 $\frac{(81 - 18.31)^2}{18.31}$ = 214.64

Total $X^2$ = 35.80 + 0.91 + 0.91 + 214.64 = 252.26

To the nearest tenth = 252

Degree of freedom = n - 1 = 4- 1 = 3

$X^2$ tabulated = 7.815

<em>The calculated </em> $X^2$ <em> exceeds the critical value, hence, the null hypothesis is rejected. The two genes did not assort independently. </em>
