Compare hypertonic, hypotonic, and isotonic solutions. When an environment is hypotonic, what happens to the cell?

algol13

When an environment is hypotonic, the cell has more solute so solvent move from outside the cell to inside causing the cell to swell.

WHAT IS TONICITY?

Tonicity is the ability of a solution to induce water loss or water gain in a cell. A solution can either be; hypertonic, hypotonic or isotonic

A hypertonic solution has more concentration of solute than its surroundings while a hypotonic solution has less concentration of solute compared to it's surroundings.

If a hypotonic solution has less solute, this means that it will have more solvent (water). Based on the principle of osmosis, water moves from a region of high concentration to region of low concentration.

Hence, water will move into a cell that is located in a hypotonic environment, causing it to swell.

DNA replicated. Genetic sameness. Genetic variation. Meiosis. Mitosis. Nuclear division. Produces gametes. Which one does it go

Oksana_A [137]

I don’t understand the question but here is what I understood:
DNA replication is for Both
Genetic Sameness is Asexual Reproduction
Genetic Variation is Sexual Reproduction
Meiosis is Sexual Reproduction
Mitosis is Asexual Reproduction
Nuclear division is both
Produces gametes is sexual reproduction.

I hope I answered your question properly. :)

Imagine that you've discovered a regulatory sequence thousands of base pairs away from the promoter and that when this sequence

Tresset [83]

Answer:

An Enhancer

Explanation:

Enhancers are the regulatory sequences and are generally located 80-160 base pairs upstream of the transcription start site. Enhancers have bidirectional elements that are involved in the initiation of transcription. Enhancers serve as the binding sites for activators to increase the concentration of activators in the vicinity of the promoter and thereby increase the rate of transcription of the gene.

According to the given information, the loss of a regulatory sequence led to a reduced level of transcription of the gene. This means that the regulatory sequence was involved in the upregulation of transcription. The presence of the sequence far away from the promoter makes it an enhancer.

What can you determine about mechanical energy from this graph?

Pachacha [2.7K]

Answer:

What can be determined from the graph includes;

a) The Mechanical Energy M.E. = 1.0

b) The initial K.E. = 1.0, The initial P.E. = 0

c) The period for the kinetic energy = The period for the potential energy = 0.25

d) The frequency of oscillation of the kinetic and potential energy = 4 Hz

e) The object starts with its maximum velocity

Explanation:

The equation between kinetic energy, K.E., potential energy, P.E. and total mechanical energy, M.E. is given as follows;

M.E. = K.E. + P.E. = Constant

From the graph, we have;

a) M.E. = K.E. + P.E. = 1.0

b) At time t = 0,

The initial K.E. = M.E. = 1.0, P.E. = 0

At time t = 0.125,

P.E. = M.E. = 1.0, K.E. = 0

c) The period for the kinetic energy, K.E. = The period for the potential energy, P.E. = 0.25

d) The frequency of oscillation of K.E. and P.E. = 1/T = 1/0.25 = 4 Hz

e) The object starts in motion with maximum velocity at time t = 0.

Which lobe of the cerebral cortex is most directly involved in touch and body position?

frosja888 [35]

The lobe in the cerebral cortex which corresponds to the touch and body position is the Parietal Lobe. It is placed in the middle portion of the brain. A part of the brain called somatosensory cortex is situated in this lobe which is important in dealing the body’s senses.
