Answer: There can be a ton of damage done if water lilies overgrow.
Explanation:
Water lilies protect the organisms under the body of water and provide shade to the plants and organisms underneath. These are very important for organisms, as they also provide a place to rest. But if the entire water surface were to be covered with water lilies, this would be a major problem, because sunlight would have no way of reaching below the surface, and this would decrease oxygen levels for plants and organisms. Without air and sunlight, plants will start to die and organisms of the body of water will also start to die because of no air to breathe. Also, overgrowth of water lilies causes water stagnation and leads to excessive algae blooms. The stagnant water attracts insects like mosquitoes, cockroaches, termites, and more pests which can harm plants and organisms.

In corn, red kernel color (R) is dominant to yellow (r) and smooth kernel texture (W) is dominant to wrinkled (w).
Corn heterozygous for kernel color and kernel texture are interbred resulting in the following offspring.
330 red smooth
97 red wrinkled
101 yellow smooth
32 yellow wrinkled
Perform a Contingency Chi-Square analysis and determine if kernel color is independent of kernel texture.
a. Show your DF, chi square value, and p value
b. Do you reject or fail to reject the null hypothesis?
c. Is kernel color independent of kernel texture?
Answer:
a. df = 3, chi-square = 1.7333, p value = 7.815
b. we fail to reject null hypothesis
c. it is independent of kernel texture
Explanation:
h0; there is independence
h1; no independence
9:3:3:1 this is the phenotypic ratio
9+3+3+1 = 16
330 red smooth + 97 red wrinkled + 101 yellow smooth + 32 yellow wrinkled
total observed = 560
1. the degree of freedom = n-1
n =4, 4-1 = 3
to get the chi square computation
(O-E)²/E
expected value for red smooth,
9/16 x 560 = 315
chisquare = (330-315)²/315 = 0.7143
expected for red wrinkled
3/16*560 = 105
chisquare = (97-105)²/105 = 0.6095
expected for yellow smooth
3/16*560 = 105
chisquare = (101-105)²/105 = 0.1524
expected for yelow wrinkled
1/16 * 560 = 35
chisquare = (32-35)²/35 = 0.2571
total chisquare = 0.7143+0.6095+0.1524+0.2571
= 1.7333
with probability = 0.05, df = 3, the value of the chi square from x² table = 7.815
1.7333 < 7.815
so we fail to reject the null
c. we conclude that kernel color is independent of kernel texture
One weakness of the human microbiome project is its use of Sanger Sequencing instead of modern metagenomic techniques. it's underrepresentation of non-US born people. it's inclusion of multiple lifestyle attributes. its sampling of people with a wide variety of diets preventing analysis of risk groups. the lack of information sharing from the project's findings.
Answer:
The correct answer is - It's a sampling of people with a wide variety of diets preventing analysis of risk groups.
Explanation:
The correct answer among the given option would be that people with more diverse diet variety would be preventing the analyzing the risk groups. It is known that the human microbiome project believes that every individual experiences a specific and unique effect of the microbiome.
Even in the case of two distinct organisms have the same microbiota will experience different effect and show different characteristics to one another due to varieties and difference in their diet.

9. How did life on Earth change from one period of geologic time to the next?
Answer:
Scientists use the geologic time scale to illustrate the order in which events on Earth have happened. ... They used relative dating to divide Earth's past in several chunks of time when similar organisms were on Earth. Later, scientists used absolute dating to determine the actual number of years ago that events happened.
Life on Earth greatly change from one period to the next of geologic time.
The life on Earth change from one period of geologic time to the next because major changes appear on the surface of earth. Great changes in the environmental conditions leads to the change in the distribution of organisms as well as extinction of various organisms on which other organisms depend.
Due to this extinction of different organisms imbalance occurs within the ecosystem so we can conclude that life on Earth greatly change from one period to the next of geologic time.

short note on occurrence of water in different source and state
Answer:
Water circulates in nature through a continuous and permanent process called the hydrological cycle or the water cycle. In this process the physical and biological elements of nature intervene, atmosphere, rain, water from lakes, rivers and seas, soil and vegetation. Water is in several states: solid state, which is ice. Liquid state, includes groundwater, which is found in the deep layers of the soil, and surface water, which includes innumerable rivers, and a gaseous state, which is found in air and clouds.
Explanation:
Water covers 71% of the earth's surface. The water cycle comprises three phases: Evaporation, filling the atmosphere with large amounts of water vapor (gaseous state). Condensation, forming water droplets in the form of a cloud or mist. Precipitation: the water vapor that is the clouds cools and precipitates in the form of rain, hail or snow. When the rain falls, some of the water is retained in the dense foliage and branches of the trees. Another seeps into the ground, forming the layers of underground water and the other part drains superficially forming streams, rivers or increasing their flow. All water, through evaporation, can change back to the gaseous state, restarting the water cycle. On our planet, water is located mainly in the oceans where 96.5% of total water is concentrated, glaciers and polar caps have 1.74%, underground deposits in (aquifers), and continental glaciers represent the 1.72% and the remaining 0.04% is distributed in decreasing order between lakes, soil moisture, atmosphere, reservoirs, rivers and living beings. Water is found in nature in three different forms or states in: solid state, such as ice, hail or snow, liquid state, such as the water we consume and the water of the seas, rivers and lakes and in the gaseous, when it forms clouds or steam that comes out of boiling water.

Petrus brings his 87-year old grandmother to the emergency department where you work. His grandmother has a fever, is dehydrated and confused, and complains of pain when urinating. Petrus reports that she has not been eating or drinking, but she has no signs or symptoms of gastrointestinal distress. You request blood samples and also a urine sample. You decide to keep Petrus' grandmother in the hospital so that she can be given intravenous fluids. You also want to wait for the lab test results before you decide whether she required additional treatment or if she can return home.
1. When Petrus' grandmother's test results are sent to you, you discover that while her blood work is normal, her urine has Gram-negative bacilli in it. Based on this, you know that the cells are:______.
a) stained blue and are cylindrical in shape.
b) stained purple and are cylindrical in shape.
c) stained pink and are spherical in shape.
d) stained pink and are cylindrical in shape.
e) stained green and are oval in shape.
2. Petrus asks you what the Gram-negative result means and you explain that the bacteria causing his grandmother's UTI:____.
a) have a thin cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
c) have no cell wall but they have a thick outer membrane which makes the cells less sensitive to the antibiotic penicillin.
d) have a thin cell wall and an inner cell membrane which makes the cells less sensitive to penicillin.
e) have no cell wall which makes the cells more sensitive to the antibiotic penicillin.
Answer:
d) stained pink and are cylindrical in shape.
b) have a thick cell wall and an outer membrane which makes the cells less sensitive to the antibiotic penicillin.
Explanation:
Gram-negative bacteria are bacteria that do not retain the crystal violet stain. So they stain in pink and they have an outer cell membrane unlike gram positive bacteria.
