Answer..
Definition Of polar molecules and nonpolar molecules please?
Answer:
Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.
Explanation:
When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

scientists have discovered a mutation that prevents the formation of which are responsible for separating chromosomes
The chromosomes are separated by a structure called the mitotic spindle. The mitotic spindle is made of many long proteins called microtubules, which are attached to a chromosome at one end and to the pole of a cell at the other end. The sister chromatids are separated simultaneously at their centromeres
elect the correct statement regarding the lungs. Select one: a. The left lung is larger than the right lung. b. Only the right lung has a hilum. c. The left lung contains three lobes while the right lung contains two lobes. d. The left lung has more bronchopulmonary segments than the right lung. e. The left lung contains two lobes while the right lung contains three lobes.
Answer:
The right lung is smaller than the right to make room for the heart.
Explanation:
so the answer is A :)
The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.
The statement that the left lung contains two lobes while the right lung contains three lobes is correct.
The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.
This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.
Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.
Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

Answer: different species
Explanation: They live in the same community like a Gouldian finch and a Double-Barred finch but are different species
However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.
What shows the low light in the evening?The hours of low light in the evening shows that it would be when humans would be most at risk from dangers. Species might make sense to seek shelter during this period.
As a result of their divergent evolutionary paths, various species have evolved in various ways to adapt to their habitats. The reason a certain species is nocturnal or diurnal has a variety of different potential causes. Perhaps at night, when light levels are low, when humans would be most exposed to dangers. The decision to seek sanctuary during this time may therefore be justified. Considering the various predatory dangers that mice and rats encounter, it is possible that being active at night reduces the threat posed by predators like birds who utilize their visual senses to identify prey.
Therefore, However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.
