A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage. Which type of selection will this population of plants most likely experience? directional selection disruptive selection species selection stabilizing selection
Answers
Answer: D
Explanation: A population contains short plants and tall plants. The short plants are not able to compete with tall plants for sunlight. The tall plants, however, are more susceptible to wind damage.
Which type of selection are the plants experiencing?
directional selection
disruptive selection
If tall and small plants coexist in a population. Short plants are unable to compete for sunlight with tall plants. However, tall plants are more vulnerable to wind damage, it experiences stabilizing selection, hence option D is correct.
What is stabilizing selection?A form of natural selection when genetic diversity declines as a population stabilizes on a given trait value.
Disruptive selection's opposite is stabilizing selection. It favors the intermediate variants rather than people with extreme traits.
The more severe phenotypes are typically eliminated through stabilizing selection, which leads to the reproductive success of the average or typical phenotypes.
Therefore, stabilizing selection this population of plants most likely experience.

What happens to water in the atmosphere as it rises? a. It evaporates. b. It condenses and forms clouds. c. It combines with other gases in the air. d. It is used up. Please select the best answer from the choices provided A B C D
Answers
Answer:
b. It condenses and forms clouds
Water in the atmosphere of the Earth evaporates into water vapor that rises into the sky and condenses to form a cloud that will dissipate with the wind, returning water to Earth, hence option B is correct.
How water condenses?Water travels everywhere over the Earth on a motorway in the sky called the atmosphere. Mist is created when a water molecule condenses on airborne particles.
It is typical in exhaled air in the cold, cold air over warmer water, and in a sauna's steam chamber. The process is the opposite of evaporation, in which liquid water turns into a vapor.
Therefore, as the air surrounding the atmosphere can cool, the water vapor reaches its dew point and condenses into liquid drops of water, hence option B is correct.

someone please calculate the ratio of offspring please help pleaseeeeeeeeeeeeeeee
Answers
Answer:
2. 1 Pink : 1 white
3. 1 Red : 1 Pink
4. 1 Red : 2 Pink : 1 White
Explanation:
This question involves a single gene coding for flower colour in snapdragon plants. The alleles of the gene exhibits incomplete dominance i.e. the red allele (R) ia not completely dominant over the white allele (W), hence an intermediate pink phenotype (RW) is formed. Based on this, a red snapdragon will have genotype, CRCR while a white one will have genotype, CWCW. The intermediate pink phenotype will have a genotype, CRCW.
The image attached to this question shows four crosses between different traits.
In the second cross between a pink (CRCW) and white offspring (CWCW), 2pink and 2white offsprings will be possibly produced in the ratio 1:1.
In the third cross between a red (CRCR) and pink (CRCW) snapdragon, 2 red and 2 Pink offsprings will possibly be produced in a ratio 1:1.
In the fourth cross between a pink (CRCW) and pink (CRCW) snapdragon, red, pink and white offsprings will be produced in the ratio 1:2:1.
See attached image for the complete punnet square. Note that, there was a mistake in the Genotype of the last cross i.e. pink has genotype CRCW not CWCW.

Use your calculated discharge results to estimate the probability of flooding, using the following procedure: 1. Use the Annual Exceedance Probability Chart below (also in the Chapter 16 Investigation in your textbook or on the worksheet that corresponds to this exercise). Find the position of your calculated discharge to fill the notch on the vertical axis of the plot. 2. Draw a horizontal line from that value to the right until you intersect the probability line. 3. From the point of intersection, draw a vertical line down to the horizontal axis of the plot, read off the corresponding probability of exceedance, and choose the best answer below. The probability to fill the notch is: Now determine the probability of flooding of the middle terrace, using the same approach as before. Remember you must use the total amount of discharge required to fill the notch and bottomland up to the level of the middle terrace. Choose the best answer below. The probability of flooding the middle terrace is:
Answers
Answer:
1) The probability to fill the notch is greater than 95%
2) The probability to fill the middle terrace is 5 to 25 percent
Explanation:
1) The calculated discharge, [tex]D_{ca}[/tex], to fill the notch is given by the relation;
[tex]D_{ca}[/tex] = Width × Depth × Velocity = 8 × 5 × 0.5 = 20 m³/s
From the Annual Exceedance Probability chart, the exceedance probability is greater than 95%, therefore, the probability to fill the notch is greater than 95%
2) The calculated discharge, [tex]D_{mt}[/tex], to fill the middle terrace is given by the relation;
[tex]D_{mt}[/tex] = Width of middle terrace × Depth of middle terrace × Velocity of middle terrace + [tex]D_{ca}[/tex] = 35 × 2 × 1.4 + 20 = 118 m³/s
From the Annual Exceedance Probability chart, the probability to fill the middle terrace is 5 to 25 percent.

Sequence the steps, 1–4, in the order required to create a permanent slide of human cheek cells. [1 mark] Specimen dehydrated Specimen embedded in wax Specimen cut into thin 'sections' Staining
Answers
Answer:
The correct order is dehydration, embed in wax, cut into sections, staining
Explanation:
There are certain proceedings needed to obtain stained sections of vegetable or animal tissues for their microscope observations.
These steps are:
Obtention of the material: The tissue is cut to an adequate size.Fixation: When tissues are extracted from the organism, they suffer autolysis and putrefaction, so they need to be fixated in order to keep their cells in the best state possible. Fixation involves preserving the original morphological and molecular characteristics of the tissue. Fixation avoids autolysis, putrefaction, distortion, and retraction of cells and the tissue that could affect its volume or morphology. Dehydration. Once fixated, the fixator must be eliminated and the tissue is dehydrated by using a gradual series of solutions with alcohol in ascendant concentrations. Dehydration must be gradual to avoid tissue deformation. Inclusion. To obtain thin cuts that can be observed under the optic microscope, the tissues must be included in a consistent, firm substance, that might be either hydrophilic or hydrophobic. A hydrophobic medium is paraffin wax, that provides hardness and plasticity. Cut. The tissue included in wax must be cut in slides or sections thin enough to allow the diffusion and penetration of light. A microtome is used to perform these cuts. When using paraffine for tissue inclusion, the cuts are about 5 to 20 micrometers of thickness. Stain. Once the cuts are performed, paraffin wax must be eliminated. This can be done by using an organic solvent. Then the tissue must be stained. Hematoxylin and Eosin are the most common dyes. Animal tissues in general do not have any natural color, so they need to be stained to be observed.humans and plants have the same type of cells?
