Describe the water cycle in a brief paragraph. Use terms that you know are associated with the water cycle.
Answer:
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... As clouds move up and over mountains, the water vapor condenses to form precipitation and freezes.
Assume that plant height is determined by a pair of alleles at each of two loci (A and a, B and b) that are additive in their effects. Further assume that each allele represented by an uppercase letter contributes 6 feet to height and that each allele represented by a lowercase letter contributes 2 foot to height. If a plant with genotype AaBB is crossed to a plant with genotype aaBb, what heights are expected in the progeny
Answer:
16 feet, 20 feet, and 12 feet
Explanation:
Uppercase allele = 6 feet
Lowercase allele = 2 feet
First, let us look at the outcome of the cross between AaBB and aaBb.
AaBB x aaBb
Progeny:
4 AaBB = 6+2+6+6 = 20 feet
4 aaBB = 2+2+6+6 = 16 feet
4 AaBb = 6+2+6+2 = 16 feet
4 aaBb = 2+2+6+2 = 12 feet
The heights expected in the progeny are 16 feet, 20 feet, and 12 feet.

Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

Answer and Explanation:
Variable: dissolved oxygen
Title: Oxygen variation as a water quality indicator.
Purpose: To study how dissolved oxygen varies with depth
Hypothesis: The percentage of dissolved oxygen will decrease as depth increases.
Procedure/Method:
Selection of sampling spots, according to the morphometry of the lake, different depth, water currents inputs and outputs, aquatic vegetation, and lake type of use. In each spot water samples will be taken using a Niskin bottle. The sample will be taken from different depth: 5 meters deep, 10 meters deep, and 15 meters deep (photic zone). Dissolved oxygen (DO) will be measured in each sample, by using a multiparameter sensor. In a field sheet to evaluate the parameter, the %DO by site and depth will be recorded.Observations:
%DO in each site and depth will be recorded in order to analyze how it varies with depth.
Data analysis:
According to different indicators of water quality in a lake, the observed %DO will be compared and analyzed to evaluate the sanity state of the lake water. Example of valuation scale,
NORMAL index: Oxygen concentration in the water column is found to be sufficient for the fish survival
REGULAR: Decrease in oxygen concentration at greater depth, values below saturation in the background
CRITICAL: Null oxygen concentration in all or part of the column profile of water. Probable fish mortality events.
According to the taken data, observations on the study site will be taken, such as the variation in oxygen concentration as it gets deeper, until reaching hypoxia level, where fishes can not survive. Data can be presented in tables and in graphs, in both cases comparing sampling sites and depth, making a focus on the valuation scale.
Conclusion:
Association of the oxygen variation with the sanity state of the lake, microbiology decomposition processes at different depths, eutrophication state, among others.

You are doing lab work with a new species of beetle. You have isolated lines that breed true for either blue shells and long antenna or green shells and short antenna. Crossing these lines yields F1 progeny with blue shells and long antenna. Crossing F1 progeny with beetles that have green shells and short antenna yields the following progeny: Phenotypes Number Blue shell, long antenna 82 Green shell, short antenna 78 Blue shell, short antenna 37 Green shell, long antenna 43 Total 240 Assuming that the genes are linked, what is the map distance between them in m.u.
Answer:
The map distance = 33.3 cM
Explanation:
Let us take,
BBLL as blue shell, long antenna .........Parent 1
bbll as green shell, short antenna .......... Parent 2
Then, cross between parent 1 and parent 2, which is
BBLL X bbll
The F1 generation will be heterzygous
BbLl as blue shell, long antenna ...... F1 offspring
By the test cross,
BbLl X bbll :
given,
BL/bl = 82 : Parental
bl/bl = 78 : Parental
Bl/bl = 37 : Recombinant
bL/bl = 43 : Recombinant
Total = 240
Recombination frequency = { [tex]\frac{Number of recombinants}{Total offspring}[/tex]}*100
= (80/240)*100 = 33.33 %
Thus, the map distance = 33.3 cM

How the coin flip relates to the probability of inheriting genetic condition?
Answer:
A coin represents a diploid, heterozygous cell with its heads and tails sides. The act of tossing the coin to land on heads or tails, provides an apt representation of the segregation of alleles during meiosis in the formation of gametes.
or i guess you could just say its all by chance ;P
peace :)

The population in a 50 square mile area is 200 people. What is the population density?
Answer:
[tex]\rho _{population}=4\frac{people}{mi^2}[/tex]
Explanation:
Hello.
In this case, since the population density is computed by dividing the amount of people by the space (area) where they are in:
[tex]\rho _{population}=\frac{people}{area}[/tex]
For 200 people living in a 50-mi² area, the population density is:
[tex]\rho _{population}=\frac{200people}{50mi^2}\\\\\rho _{population}=4\frac{people}{mi^2}[/tex]
It means that 4 people live per square mile area.

Answer:
These are locking like staphylococcus...!
Explanation:
Meristamatic cells of onion root tip are displayed in the picture. This renders the most desirable and suitable raw material to study the different stages of mitosis.
What are meristematic tissue?A meristem is a particular kind of tissue that can be found in plants. It is made up of cells that have not undergone differentiation and are able to divide. Meristematic cells have the potential to differentiate into all of the other types of tissues and organs that can be found in plants. These cells will continue to divide until they reach a certain point, at which point they will begin to differentiate and will no longer be able to divide.
Additionally, meristematic tissue is responsible for the generation of secondary tissues like wood and cork. Both primary growth (expansion) and secondary growth (thickness) contribute to the plant's overall development.
Apical meristems are the cells that are responsible for the growth of the plant's primary body as well as the extension of its roots and shoots. Because they are the cells that are responsible for secondary growth, also known as an increase in stem girth and thickness, lateral meristems are also referred to as secondary meristems.

Explain why habitats with high biodiversity tends to contain narrow ecological niches and white habitats?
Answer:
because they reduce interspecific competition
Explanation:
Narrower niches are known to be more specific and limited compared to broader niches, which are generally less specific and less limited. The species that live in broad niches are named generalists because they are able to withstand different conditions. A narrow niche is often correlated with reduced overlap and thus tends to reduce interspecific competition. For example, coral reefs consist of a wide variety of species (including anemones, sea sponges, sea fans, brain corals, etc) which have narrow niches, thus showing high biodiversity.
