The image below shows part of the surface of a leaf.
0.1 mm x 0.1 mm
The length and width of this piece of leaf surface are both 0.1 mm
Calculate the number of stomata per mm of this leaf surface.
Answers
Explanation:
You didn't attach a picture so i'll just explain how to find the number of stomatas/mm^2.
first you find the surface by multiplying the length by the width
0.1*0.1=0.01mm^2
now you count the numer of stomatas in the picture
in0.01mm^2 you have.........................x stomatas
in 1mm you have ...............................y stomatas
y=100x
Which of the following characteristics of a population will make it better able to adapt to environmental changes?
A.Rapid production of many offspring.
B.Specialization in one type of food source.
C.Large amount of inherited genetic variation.
D.Isolation to a limited geographic range.
Answers
Answer:
C
Explanation:
Answer: C. Large amount of inherited genetic variation.
If you had a population where the genetic variation wasn't as high or practically non-existent, then that population is likely suited to that very narrow specific environment. If the environment doesn't change, then the population wouldn't have a problem. However, the environment isn't likely to stay static. Things change all the time and this change will bring challenges to the population that was suited for the old environmental conditions.
Populations with high genetic variability will have some individuals thrive while some unfortunate members will perish. The members that die off are likely the ones who cannot adapt to the changes. As the environment changes, the individuals who survive will pass on their DNA to their offspring, allowing for natural selection to reinforce those favorable traits. Since the environment is constantly changing, whether that change is slow or fast, this means the process is continued indefinitely. So that's why high genetic variability is favored.

For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?
a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis
Answers
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) Diffusion: it is a passive trans-membrane transport mechanism.
b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.

Dr. Sanchez and her team have observed an unusual star in the Andromeda galaxy. Their data suggests that the star is being consumed by a nearby black hole. They write a scientific paper about their work and submit it to a scientific journal. Other scientists read their paper and look for the unusual star as well. The other scientists are participating in which activity?
Answers
Answer:
so the answer is peer review
Explanation:
Yes, other scientists are participating in this activity not in a direct way but in an indirect way. The scientists are participating in peer review.
What is galaxy?The scientific paper was written by scientists which provide the data and conclusion of entire experiments. To write scientific experiments we need to collect data, frame hypotheses, research methodology, and find out the conclusion are some of the steps to writing a scientific paper.
Testing hypotheses often involves designing experiments. In the given experiment Dr. Sanchez found that star is consumed by a nearby blackhole. But other scientist found the unusual star as well.
This suggests that both scientist thought on different aspect. This suggest peer review.
Therefore, Yes, other scientists are participating in this activity not in a direct way but in an indirect way.

Would the distance from the Sun to the next closest star be more or less than
39.4 Astronomical Units? Why or why not?
Answers
Answer: The distance from the sun to the closest star would be less. I dont know why, but their is a star that is close to the sun. The average distance between them is about 23 astronomical units. 23 is of course less then the 39.4. Also the 23 is a little more than the distance between the sun and Uranus.
Explanation: ( This is new information, not old.)
The distance from the Sun to the closest star cannot be less than 39.4 AU because both stars will start attracting each other.
Astronomical Units:An astronomical unit is equal to the distance between the earth and the sun.The nearest star from our sun is Alpha Centauri which is 4.367 light-years away from our sun.If a star is just 34 astronomical units away from our sun, the sun and the closest star will start attracting each other due to the high gravitational force. This event results in the destruction of the solar system.Therefore, the distance from the Sun to the closest star cannot be less than 39.4 AU.
