Scientists are studying how the construction of a farm affects the blood diversity of insects in a forest before the Farm was constructed 186 insect species were present the scientist find out that after the farmers constructed the number of insect species decreased By 4% per month. Based on this trend which function could be used to calculate how many months, f(n) it Will take for the number of insect species to reach the value of N?
Answers
Answer:
The function [tex]f(n)=log_{0.96}(\frac{n}{186})[/tex]
Explanation:
Wherever we are studying logarithmic decrease or increase, we can construct our logarithmic function following the next recipe :
[tex]f(n)=log_{x}(\frac{n}{y})[/tex] (I)
Where [tex]''n''[/tex] is the value that we want to obtain (following a logarithmic decrease or increase).
Where [tex]''f(n)''[/tex] is the time needed to obtain that variation.
Where [tex]''x''[/tex] is the parameter related to the percentage decrease or increase
And where [tex]''y''[/tex] is known as the original population.
Now let's use the question to learn how to use the expression (I) :
In order to find the parameter [tex]''x''[/tex] we need to know how porcentual the population changes. We know that the number of insect species decrease by 4 % per month.
Therefore, for the initial month we will have the 100 % of the number of insect species. For the first month we will have a decrease of 4 % which can be written as the 96 % of the original population.
We write 100 % - 4 % = 96 % ⇔ [tex]1-0.04=0.96[/tex]
That's how we obtain the parameter [tex]x[/tex]. In this case we subtract 0.04 to the original population 1 because we have a decrease. Otherwise we would have added if we had had an increase. The number 0.96 represents that month by month we obtain the 96 % from the previous month. The value from the parameter is [tex]x=0.96[/tex]
Now the original population of insect species is [tex]186[/tex]. Therefore the value for [tex]y[/tex] is [tex]y=186[/tex]. Using the values obtained in the expression (i) we have :
[tex]f(n)=log_{0.96}(\frac{n}{186})[/tex]
For example,
We have [tex]186[/tex] number of insect species at the time origin. A decrease of 4 % can be calculated as
[tex](186)(0.96)=178.56[/tex] which is the value expected for the first month. Now if we use this value in the expression (I) :
[tex]n=178.56[/tex] ⇒ [tex]f(178.56)=log_{0.96}(\frac{178.56}{186})=log_{0.96}(0.96)=1[/tex] ⇒
[tex]f(178.56)=1[/tex]
This means that to obtain 178.56 number of insect species we need to wait one month to achieve this value. Which fits with the problem data.
Answer:
f(n)=log0.96(n/186)

It fertilizes soil
It contains carbon
It is only found in topsoil
It erodes the rocks in soil
Answers
It forms from dead plants
It fertilizes soil
It contains carbon
It is only found in topsoil (not sure abt this tho)
Humus forms from dead plants, fertilizes soil, contains carbon, and is only found in topsoil. The correct options are A, C, D, and E.
What is humus?When plant and animal debris decomposes in the soil, humus, a black, organic substance, is created.
Plants scatter leaves, twigs, and other debris to the ground, which accumulates. Leaf litter is the name of this substance. Animal carcasses contribute to the litter after they pass away.
Humus is a form of soil produced by decomposing organisms and plants.
The name was developed by a French soil expert named Muller and is based on the Latin word "soil". Humus is challenging to define and is still not completely understood.
Only found in topsoil, humus is a material that develops from dead plants, fertilizes the soil, and contains carbon.
Thus, the correct options are A, C, D, and E.

b) Skeletal developments leading to the amphibian movement onto land probably evolved from lobe-finned fishes.
d) The anterior gill arch formed the basis for the evolution of the vertebrate jaw.
Explanation:
The animals we know today have physical characteristics that are evolutionary adaptations of characteristics of their ancestors, which have undergone a series of evolutions and modifications over the years giving rise to new species that have resulted in the species we know today. This process of evolutions and adaptations also happened with the ancestral species of fish, which allowed that today, they had characteristics such as teeth and jaws. Many of these evolutions occurred even in different species, such as the evolution that allowed the amphibians to have a skeleton, which evolved from the spine fins of fish.

Answers
The introduction of invasive species is not a way to improve biodiversity.
• An organism, which causes economic or ecological harm in a new environment where it is not native is known as an invasive species.
• It can harm the natural resources in an ecosystem and at the same time can hamper human use of these resources.
• An invasive species can be a kind of plant, amphibian, insect, fungus, fish, bacteria, etc. and is not native to an ecosystem and results in harm.
• They possess the tendency to cause extinctions of native animals and plants, decline biodiversity, by competing with local species for limited resources, and changing habitats.
Thus, introducing invasive species is not a way by which humans can improve biodiversity.

What is photosynthesis?
Photosynthesis is the process whereby plants manufacture their own food with the use of sunlight and carbon dioxide.
When this occurs, (energy in form of glucose) and oxygen are produced. The oxygen is released for animals to use.
Thus, producers capture energy from the sun and use it to create simple organic molecules, which they use for food. Consumers constitute the upper trophic levels.
