with such a rich diverse array of life forms how are we able to live harmoniously with each other
Explanation:
Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms. Life on earth is incredibly diverse. Biological diversity is the variety of life on earth. This includes all the different plants, animals, and microorganisms; the genes they contain; and the ecosystems they form on land and in water. Biological diversity is constantly changing. The source of this diversity is evolution, the process of gradual change during which new species arise from older species. Evolutionary biologists study the evolution of living things in everything from the microscopic world to ecosystems. There are so much duversity in life on the Earth because there are great numbers of species on the earth, the present day organism are the end product of about 3.5 billion years of organic evolution on earth.
From a plant cell leucoplast is removed. What will its effect be on the cell functioning?.
Answer:
Leucoplasts (λευκός leukós "white", πλαστός plastós "formed, molded") are a category of plastid and as such are organelles found in plant cells. They are non-pigmented, in contrast to other plastids such as the chloroplast.
Leucoplasts, specifically, amyloplasts
Lacking photosynthetic pigments, leucoplasts are not green and are located in non-photosynthetic tissues of plants, such as roots, bulbs and seeds. They may be specialized for bulk storage of starch, lipid or protein and are then known as amyloplasts, elaioplasts, or proteinoplasts (also called aleuroplasts) respectively. However, in many cell types, leucoplasts do not have a major storage function and are present to provide a wide range of essential biosynthetic functions, including the synthesis of fatty acids such as palmitic acid, many amino acids, and tetrapyrrole compounds such as heme. In general, leucoplasts are much smaller than chloroplasts and have a variable morphology, often described as amoeboid. Extensive networks of stromules interconnecting leucoplasts have been observed in epidermal cells of roots, hypocotyls, and petals, and in callus and suspension culture cells of tobacco. In some cell types at certain stages of development, leucoplasts are clustered around the nucleus with stromules extending to the cell periphery, as observed for proplastids in the root meristem.
Etioplasts, which are pre-granal, immature chloroplasts but can also be chloroplasts that have been deprived of light, lack active pigment and can be considered leucoplasts. After several minutes exposure to light, etioplasts begin to transform into functioning chloroplasts and cease being leucoplasts. Amyloplasts are of large size and store starch. Proteinoplasts store proteins and are found in seeds (pulses). Elaioplasts store fats and oils and are found in seeds. They are also called oleosomes.
This is a question on the circulatory system. I don't understand how the pathway that the blood goes through in the heart makes it oxygenated. Could someone pleas explain to me what each part does and how when it goes to the lungs it gets oxygenated?
Answer:
deoxygenated blood is pumped back to the heart with the superior vena cava and inferior vena cava. Blood is then in the right atrium then it is pushed to the right ventricle in the heart. it is the pumped through the pulmonary artery to the lungs(the pulmonary artery is the only artery that carries deoxygenated blood). In the lungs blood is pumped to the cappilleries in the bronchus where oxygen in the air is passed through to the blood with heamoglobin and thus now the blood is oxygenated. The blood is the pumped brought back to the heart with the pulmonary vein(the pulmonary vein is the only vein to carry oxygenated blood).It flows into the left atrium where it is then pushed down into the left ventricle and is then pumped up through the aorta to the whole body.

A DNA microarray contains immobilized DNA that corresponds to different genes. The microarray is hybridized with fluorescently labeled DNA probes reverse transcribed from the control and experimental mRNA samples. The control probe is labeled with a red fluorochrome, while the experimental probe is labeled with a green fluorochrome. What will be the color of the spot representing a gene with moderately upregulated expression in the experimental sample relative to the control one
The color of the spot of a gene with moderately upregulated expression will be lime-green. A DNA microarray is a technique used to determine the expression level of many genes simultaneously.
A DNA microarray is a laboratory technique used to identify the genes that are being expressed in a cell.
A DNA microarray contains many tiny spots of specifically labeled cDNA samples referred to as probes, which can be hybridized by base complementarity to transcribed (mRNA) gene sequences.
In the DNA microarray, the probes can be fluorescently marked gene sequences.
After hybridization, the DNA microarray is then scanned in order to determine the level of gene expression of each mRNA that hybridizes with their corresponding probes on the slide.
In this case, green spots evidence genes that are being strongly expressed in the sample.

Explanation:
The element lithium has two common isotopes: Li–6 and Li–7 If the average atomic mass of lithium is 6.94004 u, determine its percent isotopic abundances. Step by step and explain.
First we need to determine the average atomic mass of these isotopes.
The atomic masses of Lithium-6 and Lithium-7 are 6.0151amu and 7.0160amu respectively.
Now that we have that, we need to set up the relative abundance problem.
We can do that using the formula (M1)(x) + (M2)(1-x) = M(E)
Because you asked for details, I'll explain what each variable stands for-
M1 = the mass of one isotope
x = the relative abundance
M2 = the mass of the second isotope
M(E) = the atomic mass of the element from the periodic table
Therefor all we do now is plug in our respective variable.
M1 = 6.0151amu (Lithium-6)
x = unknown relative abundance
M2 = 7.0160amu (Lithium-7)
M(E) = 6.94004amu
Now the formula plugged in will look like this:
6.0151x + 7.0160(1-x) = 6.94004
Now doing some quick math, we can determine that x=0.07589
For the last step we need to find the percent abundance of each element, which is quite simple. We take X and multiply it by 100 to find Lithium-6, so 0.076 x 100 = 7.6%
and since then we use 1 - X, so 1 - 0.076 = 0.924
We take that and also multiply it by 100, so 0.924 x 100 = 92.4%
Conclusion:
The abundance of the Lithium-6 isotope is 7.6%, and the abundance of the Lithium-7 isotope is 92.4%.

Which of the following is TRUE about ovarian cysts?
Answer:
d. All of the above
Explanation: is correct.
Answer:
ALL OF THE ABOVE
Explanation:
One variable not mentioned in the description of the experiment that could affect the results of the investigation is reduced canopy cover. Describe the effect that canopy cover would likely have on the results of the investigation.
The canopy cover can affect the results of an investigation because a higher canopy cover is accompanied by a decrease in the availability of sunlight.
The canopy cover is the proportion of the ground covered by vegetation when it is viewed from vertically above the planted area.
The level of canopy cover affects light availability on the ground and also its microclimate, thereby this feature can also alter any biological experimental procedure by affecting the level and type of biodiversity.
A reduced canopy cover may alter any experimental outcome by increasing the energy/light input in the ground cover stratum, thereby likely affecting biodiversity.

The toll-like receptors do NOT directly lyse bound pathogens (Option C). These protein receptors play fundamental roles in the innate immune system.
Toll-like receptors (TLRs) are single-pass membrane-spanning protein receptors that play fundamental functions in the innate immune system.
TLRs are differentially expressed on the surface of antigen-presenting cells (i.e., macrophages and dendritic cells) in order to recognize evolutionary conserved antigenic domains in different pathogenic microorganisms (e.g. bacteria).
TLRs initiate innate immune responses such as, for example, inflammatory responses, by identifying conserved pathogen-associated molecule patterns (PAMPs).
