Which of the following is a requirement for a population to be in Hardy-Weinberg equilibrium? A.Immigration must outpace emigration. B.One allele must provide a benefit.
C.No mutation can take place.
D.The population must be very small.

Answers

Answer 1
Answer:

The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection.

The correct answer is C.No mutation can take place.

What are the 5 Hardy-Weinberg rules?

A low rate of mutations would help keep a population in equilibrium. The five assumptions of Hardy-Weinberg equilibrium are:

  • large population size,
  • no natural selection
  • no mutation rate
  • no genetic drift
  • random mating

What conditions are required for the Hardy-Weinberg model to apply?

No gene flow can occur to increase variability in the gene pool. A very large population size is required to ensure allele frequency is not changed through genetic drift. Mating must be random in the population. Natural selection must not occur to alter gene frequencies.

Movement of dissolved particles across a semipermeable membrane from *high* to *low* concentration

Answers

Passive transport, or diffusion. Moves form high to low.

Final answer:

Osmosis is the movement of water through a semipermeable membrane from high to low concentration. It is driven by the imbalance in water concentration and facilitated by aquaporins. Osmosis plays a crucial role in the functioning of red blood cells and the kidneys.

Explanation:

Osmosis is the movement of water through a semipermeable membrane according to the water's concentration gradient across the membrane, which is inversely proportional to the solutes' concentration. While diffusion transports material across membranes and within cells, osmosis transports only water across a membrane and the membrane limits the solutes' diffusion in the water. Not surprisingly, the aquaporins that facilitate water movement play a large role in osmosis, most prominently in red blood cells and the membranes of kidney tubules.

Compared with formerly depressed people, those who are currently depressed are more likely to recall their parents as rejecting and punitive. this best illustratesa. the spacing effect.
b. mood-congruent memory.
c. the misinformation effect.
d. source amnesia.

Answers

b. mood-congruent memory.

Final answer:

The best option that illustrates the scenario described in the question is mood-congruent memory.

Explanation:

The best option that illustrates the scenario described in the question is mood-congruent memory. Mood-congruent memory refers to the tendency to recall information that is congruent with one's current mood. In this case, currently depressed individuals are more likely to recall memories that align with their negative mood, such as perceiving their parents as rejecting and punitive.

check my answer When you notice something using your sense of smell, taste, touch, sight or hearing you are making which of the following? A hypothesis An experiment <--- my answer A conclusion An observation

Answers

That sounds like you are observing your surroundings to me, or making an observation.

Answer:

The correct answer will be option-an observation.

Explanation:

The scientific method to explain a natural phenomenon takes place in various steps which begins with making an observation.

The step of observations involves the use of sensory organs of the body which help them observe nature.  The sensory organs involve the sense of smell, touch, sight, hearing and taste which allow the person to observe.

Thus, option- observation is the correct answer.
