Rachel ate a piece of fruit and happened to drop the seeds in her backyard. After a few weeks, she saw a small plant with flowers growing in the backyard. Which group does this plant belong to?
Answers
Answer:
Angiosperms group
Explanation:
Angiosperms or commonly referred to as "flowering plants" are the most advanced and diverse group of plants in the Kingdom Plantae. They are a plant group characterized by the possession of a reproductive structure called FlOWERS, which develop into fruit and seeds when fertilized.
Therefore, if Racheal ate a fruit and drop its fruits in the backyard, where she later noticed the growth of a flower-producing plant, it means that plant that Rachel ate is an ANGIOSPERM because it produces FLOWERS. Flower is a distinguishing factor for Angiosperms.

Answer:
10 + √10
Explanation:
Assume your triangle is like the one below.
The coordinates of the vertices are
A = (-2,-4), B = (-2,-1) A = (-2,-4)
1. Calculate AC
AC = 3 - (-2) = 3 + 2 = 5
2. Calculate AB
AB = AC = 5
3. Calculate BC
We can use the Pythagorean theorem:
BC² = BD² + CD² = 3² + 1² = 9 + 1 = 10
BC = √10
4. Calculate the perimeter
p = AB + AC + BC = 5 + 5 + √10 = 10 + √10
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.

Soil conservation is important for human agriculture because it is easier to prevent degradation of old soil than to generate new soil.
What is soil conservation?Soil conservation is a set of agricultural principles and techniques aimed at the proper management of arable land, preventing erosion in all its forms. Its objective is to make the most of the land per unit of planted area. Thus, the physical, chemical and biological degradation of the soil is avoided.
With this information, we can conclude that soil conservation is important for human agriculture because it is easier to prevent the degradation of old soil than to generate new soil.

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.

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.What can you do to prevent or lessen the generation of hazardous wastes?

Which of the following would not reduce the carrying capacity of an ecosystem for a particular prey species? a. drought b. fewer primary producers c. habitat destruction d. fewer predators
Answers
Answer:
Fewer Predators
Explanation:
.
The only thing that would not reduce the carrying capacity of an ecosystem for a particular prey species is fewer predators, which are present in Option D, as the carrying capacity refers to the maximum number of individuals present in the ecosystem.
What is carrying capacity?Various factors can affect the carrying capacity of an ecosystem for a particular prey species, such as drought and habitat destruction, which can decrease the availability of resources such as food, leading to a reduction in the carrying capacity of the ecosystem, which can result in a decrease in plant growth and food availability for herbivores, which in turn reduces the carrying capacity for predators.
Hence, the only thing that would not reduce the carrying capacity of an ecosystem for a particular prey species is fewer predators, which are present in Option D.

Answers
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.
