The tropical rain forest biome has some of the highest biodiversity on earth how would a decrease in the biodiversity due to deforestation or other factors affect the large biosphere
Answer:
Negatively.
Explanation:
A decrease in biodiversity can cause a large chain reaction within the ecosystem. A loss of species can be detrimental, especially if they're key stone species. This negative impact can cause the food chain to be disrupted which ends up affecting every organism within the environment. Every organism plays a role within the ecosystem and when one or more are removed it causes extreme disarray.
The decrease in biodiversity due to deforestation and other factors in the tropical rainforest biome will negatively affect the biosphere. Thus, the effect will be negative.
What is the biosphere?The biosphere also called the ecosphere is the sum of the total life or the ecosystem. It includes the part of the planet where life is inhabitants. It may include a mountain, roots, dessert, oceans, etc. It is interrelated to biodiversity.
If the biodiversity of a place gets declined due to factors like deforestation, pollution, poaching, natural disasters, etc. then it will affect the ecosystem. If the stone species are lost then it will have a detrimental effect on the ecosystem.
These negative consequences disrupt the food chain and will result in affecting every organism. This chain of disruption will cause an overall loss to the biosphere.

States of matter:There are three states of matter which are;
SolidLiquidGasParticle motion in the states of matter:The degree of motion of particles in the three states of matter differs. The particles of matter in a solid are compacted hence a solid has no space between particles. Particles are less compacted in the liquid phase but are very free in the gas phase.
Hence, model 1 must be the correct representation of a liquid.

this mannitol salt plate was inoculated with an unknown staphylococcus species. what can you conclude about this unknown organisms
Complete question: Analyzing Mannitol Salt Agar (MSA): An MSA plate was inoculated with an unknown Staphylococcus species. What can you conclude about this unknown organism?
A. It can ferment mannitol.
B. It produces acid during fermentation, leading to a lower pH in the medium.
C. It can tolerate higher salt concentrations.
D. It could be S. aureus.
E. All the above
Answer: The correct option is E ( all of the above)
Explanation:
Culture medium is a growth medium that is used in microbiology which permits the growth of microorganisms. It can be in a gel or liquid form. There are different types of culture medium which includes:
--> Differential medium
--> Selective medium
--> Enriched medium
Mannitol Salt Agar( MSA) is a type of selective culture media that is used in microbiology for the identification and isolation of staphylococcus species from biological samples. A typical MSA includes essential growth factors and trace nutrients such as nitrogen, vitamins, minerals and amino acids essential for growth. The medium contains sodium chloride( salt) with mannitol which is the fermentable carbohydrate source
Staphylococcus aureus organisms are capable of fermenting mannitol, produces acid during fermentation leading to a lower pH in the medium, and can tolerate higher salt concentrations. Therefore the unknown organism is POSITIVE to mannitol salt agar analysis. Thanks and I hope it helps!

I WILL GIVE BRAINLIEST Pretend you're riding the bus to school on a very cold and snowy day. List 3 different phases changes you might see along the way.
While riding the bus to school on a very cold and snowy day three different phases changes you might see along the way are mentioned below:
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3. melting(snow turning the water)
What is precipitation, evaporation, and melting?Evaporation is the process in which liquid changes in vapour or gas and it can be easily observed during hot summer days when there is raining and when wet clothes dry in the presence of sunlight. Evaporation is directly proportional to temperature and when rate of evaporation increases the temperature also increases.
Precipitation is the water that is falling from the sky and it occurs when a portion of atmosphere becomes saturated with water vapour.
Melting is the process in which solid is converted into liquid like ice cube converted into liquid water and this is one of the example of melting.
Therefore, the mentioned below are three phases changes :
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3. melting(snow turning the water)

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection
Answer:
C. group
Explanation:
Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.
What is group selection?A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.
Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.
The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.
Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.
The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing
