What is the effect of the biogeochemical cycles?
Answer:
The effect is to promote a cycling of the elements, ensuring that they are used and later available again. This is an extremely important factor, as some elements are essential for living beings, and their constant use, without replacement, could lead to the extinction of species.
Explanation:Biogeochemical cycles are processes that occur in nature to ensure the recycling of chemical elements in the environment. It is these cycles that enable the elements to interact with the environment and living beings, that is, they ensure that the element flows through the:
atmosphere hydrospherelithosphere biosphereThe main biogeochemical cycles found in nature are the:

What is the rarest eye colour in the world? Please help, it's due today.
Answer:
Green eyes
Explanation:
The production of melanin in the iris is what influences eye color. More melanin produces a darker coloring, while less makes for lighter eyes. Green eyes are the rarest, but there exist anecdotal reports that gray eyes are even rarer.
The rarest eye color in the world is green, only 2% of the population in the world have green eyes. To find out more about the list.....
1. Green eyesOnly 2% of people in the world are believed to have this eye color. It is most easily found in northern and Southern Europe and Western Asia.
2. Amber eyesThey are reddish-brown, with a golden and coppery undertone. Among the clear and beautiful eyes in the world, and according to the survey, the most iris, all eyes and beautiful in the world are according to the study, all eyes are rare and specific.
3. Red or violet eyeIt is generated by the body thanks to some genetic changes. The most common is albinism, a disease that lowers melanin levels. Because of this, the hair and eyes can be distinguished.
With this information, we can conclude that there are several eye colors, but the most rare is the color green.

The fence around the school's garden is 22.6 m. If the garden is 7.5 m long, how wide is the garden? *
Answer:
Explanation:
22.6 is the perimeter because the question has the key words "fence" and "around" that let us know.
Perimeter equation is L+L+W+W
We know 7.5 is the length (could also be the width, it doesn't matter the order)
The length appears two times, so lets plug it in-
22.6= 7.5+7.5+W+W , Now you want to combine the like terms so.. 7.5+7.5=15
22.6= 15+W+W
Now subtract the 15 from 22.6
7.6= W+W , there are two W's left so divide 7.6 by 2
7.6/2= 3.8
It is 3.8 m wide

What factors could decrease the rate of photosynthesis in a plant?
Answer: light intensity, carbon dioxide concentration and temperature i think- maybe
Explanation:
Without enough light, a plant cannot photosynthesise very quickly, even if there is plenty of water and carbon dioxide, Increasing the light intensity will boost the rate of photosynthesis and for carbon dioxide even if there is plenty of light, the plant cant photosynthesise if there is insufficient carbon dioxide. and why temperature is because if it gets too cold the rate of photosynthesis will decrease, Plants cant photosynthesise if it gets too hot either

Answer:
B
Explanation:
Pharmacodynamic tolerance involves changes in neurons, while metabolic tolerance involves changes in enzymes.
What is pharmacodynamics?
"Pharmacodynamic interactions" are interactions in which substances directly affect one another's effects. Sedatives, for instance, typically potentiate one another.
Neurons are the cells of the nervous system the cell plants are branch-like structures like the roots of a plant, they contain absorb information using electrical impulses and transport it into different areas of the brain.
The central nervous system contains the brain and the hypothalamus, and the peripheral nervous system contains all the neuron cells.
Therefore, while metabolic tolerance affects changes in enzymes, pharmacodynamic tolerance involves changes in neurons.

Why do you have to determine the total magnification when observing a specimen under the compound microscope?
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.
As a metal, lithium will lose electrons to have a ful valence shell. How manyvalence electrons will it lose to have full valence shell? What will be the charge of the lithium ion?
please help me
Answer:
It will lose 1 electron
Its charge will be 1+, or simply (+)
Explanation:
Lithium it's located in the group one of the periodic table, the Alkali, and by rule, all Alkali are always gonna loose one electron during a chemical reaction to form a positive ion.
The charge is explained by the fact that, if lithium looses one electron, then it wi have less number of electrons than protons, meaning that, if there's a higher number of protons (positive charge), then the charge will be positive. And since the atom loosed one electron then its charge will be 1+
For example, during a chemical reaction calcium is always gonna loose 2 electrons, so its charge's gonna be Ca2+

explain how the information in this diagram indicates that an oxygen atom could bond covalently to two hydrogen atoms to form water
Answer:
because when oxygen atom bonds with two hydrogen atoms they form water
Explanation:
A water molecule is formed by covalent bonds between an oxygen atom and two hydrogen atoms. The bond between hydrogen and oxygen involves unequal sharing of electron – it is a polar covalent bond. This is because the nucleus of the oxygen atom is more attractive to electrons than the nuclei of the hydrogen atom.
Explain why some parts of a plant can act as both a source and a sink.
Answer:
Some organs are both a source and sink. Leaves are sinks when growing and sources when photosynthesizing. Rhizomes are sinks when growing but become sources in the spring when they provide energy for new growth.
hope this helps ☆☆☆
The leaves and rhizomes of the plant are found to act both as a source and a sink when growing and when they perform photosynthesis.
What are source and sink in plant?
Source organs are the organs which provide a net uptake of resources while sink organs are the organs which have a net drawdown of resources in the plant. Molecular mechanisms which are responsible for the regulation of the relationship between the sources and sinks. These molecular mechanisms include both the carbon and nitrogen-containing metabolites, plant hormones and genes.
Some organs in the plant are found to act both as a source and a sink. Leaves of the plant are sinks when growing and as source when photosynthesizing in the presence of sunlight during daytime. Rhizomes are the sinks when growing however they become sources in the spring season when they provide energy for the new growth.
