what would you if cell membrane became impermeable instead of selectively permeable could cell remain alive
natali 33 [55]
If a cell membrane became impermeable, instead of selectively permeable, the cell would not remain alive, though certain organisms would be able to stay alive longer than others. This is because the cell membrane allows essential molecules and substances such as oxygen into the cell, while allowing harmful substances, like waste, out of the cell.

What are the negative consequences of improper disposal of electronic waste?​
Gre4nikov [31]

Answer:

1) Increased probability of hazardous chemical contamination.

2) Air, water, and soil pollution.

3) Mortality in both terrestrial and aquatic organisms.

4) Development of diseases in humans.

Explanation:

The improper disposal of electronic waste can have detrimental consequences for the environment and, as a result, to all living beings including humans.

If electronic waste is thrown away in an open area, it warms up and releases hazardous chemicals that are detrimental for the health of living beings. This occurs because <u>electronic objects contain toxic chemicals such as lead, mercury, cadmium, amongst others</u>.

These chemicals will eventually enter both soil and water, harming thousands to millions of terrestrial and aquatic organisms. Moreover, these chemicals will enter the food chain and, as humans consume these affected organisms, we are also affected in numerous ways. For example, ingesting these chemicals could cause reproductive issues, damage to both the nervous and digestive systems, the development of cancer, etc.

2. Trust - trust is one of the most important and essential ingredients of healthy relationships
3. Commitment - how can you be in a healthy relationship if you are not commited?

Suppose a population of flour beetles has 10,000 individuals. There are two alleles possible for the gene that determines body c
miss Akunina [59]

Answer:

0.75

Explanation:

Given frequency of the two alleles i.e "B" and "b" are equal .

As per Hardy–Weinberg equilibrium, sum of frequency of the two alleles is equal to one.

i.e p+ q= 1\\

Since p=q\\

p and q will be equal to 0.5

Frequency of genotype "BB"

= p^{2} \\= 0.5^{2} \\= 0.25

Frequency of genotype "bb"

= q^{2} \\= 0.5^{2} \\= 0.25

As per second equation of Hardy–Weinberg equilibrium,

p^{2} + q^{2} + 2pq=1

Substituting the values of p and q in above equation we get -

0.25+0.25+2pq=1\\2pq = 1-0.25-0.25\\2pq = 0.5

Red beetles have genotype BB and Bb

number of red beetles with genotype (BB)

= 0.25 * 10000\\= 2500

number of red beetles with genotype (BB)

= 0.5 * 10000\\= 5000

Total red beetles

2500+ 5000= 7500\\

Frequency of red beetles

= \frac{7500}{10000} \\= 0.75
