Answer:
With decrease in pH of ocean water, the survival rate of corals, algae, and fish in coral reef reduces.
Explanation:
Coral reefs find difficulty in living in acidic ocean water. It is so because the coral’s shell that is made up of calcium carbonate is unable to sustain in acidic environment.
Not only this the skeleton of snails, clams, algae , fish etc is also made up of calcium carbonate. Increased acidity leads to death of these species.
Thus, the lower is the pH of ocean water, the higher is its acidity and hence the lower is the probability of survival of corals, algae, and fish in the coral reef
Answer:
When you decrease the pH in the simulation, the ocean’s acidity increases. What do you expect to happen over time to the population of the corals, algae, and fish in the coral reef as the pH of the ocean decreases?

What happens if a person goes into a black hole?
Explanation:
we all find ourselves confronted with the age-old question:
what happens when you fall into a black hole?
You might expect to get crushed, or maybe torn to pieces. But the reality is stranger than that.
The instant you entered the black hole, reality would split in two. In one, you would be instantly incinerated, and in the other you would plunge on into the black hole utterly unharmed.
Hope this helps you.. Good Luck

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
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.Which of the following is an

Based on the image what would an observer see at Location A? ------------------------
(A).partial lunar eclipse
(B).partial solar eclipse
(C)total solar eclipse .
(D)total lunar eclipse
At the location A, the moon is between sun and earth. Hence, the shadow of moon partially hide sun from that region. Therefore, we can observe partial solar eclipse at location A.
What is solar eclipse ?Solar eclipse is a spatial phenomenon where, the sun is eclipsed by moon when moon comes between sun and earth. The sunlight to the earth is hindered by the moon and a shadow comes in that region of earth.
The moon only casts the outermost portion of its shadow, known as the penumbra, on earth during a partial solar eclipse because the Sun, moon, and earth are not precisely lined up in a straight line. This appears to be the sun being bit into by the moon from our vantage point.
On occasion, the moon just partially obscures the sun's disc. Sometimes a partial eclipse can be mistaken for a total one. eclipse magnitude is a measurement of the eclipsed area's size. Hence, option B is correct.

someone please calculate the ratio of offspring please help pleaseeeeeeeeeeeeeeee
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.

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.

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:
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.

Answer:
D
Explanation:
Deforestation is when forests and trees are destroyed to create space for farming and buildings or collect wood.
Many different animals live in the forests, such as birds, squirrels, bears, deer and more. This means the forest is their habitat. If the forest is destroyed, then their habitats will be destructed. This leaves some animals without shelter and some without food. Therefore, the animals may die and biodiversity will decrease.
Therefore, the best answer is D. Destruction of habitats.
