Concentration cell based on the Ni2 -Ni cell reaction.
(a) Concentrations of Ni2 (aq) in the two half-cells are unequal, and the cell generates an electrical current and a voltage.
(b) The cell operates until [Ni2 ] is the same in the two half-cells, at which point the cell has reached equilibrium and the emf goes to zero.

Answers

Answer:

Explanation:

The missing diagram contained in this question is first attached in the image below.

The objective of this question is to determine how ions migrate when the cells are operating by assuming the solutions are composed of Ni(NO3)2.

From the information provided:

In this instance, the ions tend to move first from cathode to anode in terms of raising the concentration of Ni(2+) at the anode, resulting in the development of a dead cell. The initial concentration of [Ni(2+)] in the anode solution is 1.00 × 10⁻³ M, which gradually increases to 0.5 M, during which both the cathode and the anode possess the same concentration at the same point.

This causes Q(equilibrium constant) to equal  1 as well as log(Q) to equal 0, indicating that the cell is dead.

As a result, the cell will cease to operate, and nothing will migrate from the left to the right side.

Which plants are most likely to adapt successfully to a climate change in their environment?
O A) plants that grow rapidly
O B) plants that reproduce asexually
O C) plants that are cross-pollinated
OD) plants that do not rely on wind-pollination

Answers

Answer:

A

Explanation:

plants that grow rapidly

The plants that are most likely to adapt successfully to a climate change in their environment are ; ( B ) plants that reproduce asexually

The change in climate favors some plant species while negatively affecting other plant species. most plants depend on the climate/weather like the wind for its reproduction/survival.

Most plants are cross-pollinated while some are wind pollinated therefore they will require the right weather/wind conditions to adapt and survive in their environment, plants growing rapidly can be hindered by changes in climate conditions.

But plants that reproduce asexually do not rely on the climate conditions to carry out their reproductive activities which makes them the most likely to adapt successfully to a climate change in their environment.

Hence we conclude that The plants that are most likely to adapt successfully to a climate change in their environment are  plants that reproduce asexually

a. True
b. False

Answers

Answer:

Plasma estrogen levels reach their peak at the end of the luteal phase of the ovarian cycle.

a. True

Explanation:

A woman's estrogen levels become highest towards the end of her ovulation.  At this point, the woman is naturally prepared for a possible pregnancy.  The occurrence of the highest estrogen levels coincides with the luteal phase, a stage of a woman's menstrual cycle, which occurs after ovulation (or the release of eggs from the ovaries), and before the start of the normal period. This luteal phase has been observed to be within 14 days for all women.  By the end of the luteal phase, the corpus luteum function declines.

would occur if we were suddenly thrown back into the “Dark ages” with no use of technology

Answers

So there are a lot of people who say that the Dark Ages, lasting about 1,000 years, set humans back technologically. However, some say that since the Dark Ages really only affected Western Europe, and not the Middle East or Asia, it wouldn't make a difference.

If there had been no "Dark Ages" there would have been no Renaissance. Historians actually argue about when Renaissance started, and the answer is than it is not possible to pinpoint a date. The Crusade did more to bring the eastern world to western Europe than they did to divide.

Answers

A county has recently evolved from underdeveloped to developed and the birth and death rate have stabilized, This is known as Demographic transition. Thus, the correct option is B.

What is Demographic transition?

Demographic transition is a phenomenon and the theory which refers to the historical shift from the high birth rates and high death rates in the societies with minimal technology, education especially of the women of the society and the economic development, to the low birth rates and low death rates in the societies with advanced technology, education and economic development of the whole society, as well as the different stages between these two scenarios.

The rise in the demand for human capital and its impact on the decline in the gender wage gap of the society during the nineteenth and the twentieth centuries period have contributed to the onset of the overall demographic transition of the society as a whole.

Therefore, the correct option is B.

Which type of cell division causes a puppy to grow into an adult dog?
meiosis
mitosis
eukaryotic
O homeostasis

Answers

Answer is mitosis

Meiosis is for sexual reproduction and for producing offspring, whereas mitosis is the cell division for cell reproduction so it has to be mitosis as it is the cause of cell growth, allowing the puppy to grow into an adult dog

It wouldn't be eukaryotic or homeostasis since they're not types of cell division.

Mitosis is the kind of cell division which allows a puppy to develop into an adult dog. So, the correct option is B.

What is Mitosis?

In eukaryotic cells, a process called mitosis produces two daughter cells, each of which has the same amount of chromosomes as the parent cell. Multicellular organisms, like dogs, go through a process called mitosis during which cells divide and differentiate into different cell types.

The process of meiosis, on the other hand, produces gametes with half as many chromosomes as the parent cell and is only able to occur in specialised cells, such as the ones involved in sexual reproduction. Contrarily, homeostasis has nothing to do with cell division and instead refers to the preservation of a constant internal environment within an organism.

Therefore, the correct option is B.
