Answer:
Soils play a key role in the carbon cycle by soaking up carbon from dead plant matter. Plants absorb CO2 from the atmosphere through photosynthesis, and pass carbon to the ground when dead roots and leaves decompose. This net release of carbon to the atmosphere contributes to global warming.

Describe a cause of aerosol (particulate matter) pollution; then briefly explain its effect on human health.
A major cause of aerosol pollution is the burning of fossil fuels, such as coal, oil, and natural gas for transportation, energy production, and industrial processes.
What is aerosol pollution?Aerosol pollution is also known as particulate matter pollution. It refers to the presence of tiny solid and liquid particles which are known as particulate matter, in the air. These particles can come from a variety of sources, including vehicle exhaust, industrial processes, construction activities, wildfires, and dust storms.
Aerosol pollution can various harmful effects on human health, as the tiny particles can easily penetrate deep into the lungs and bloodstream when inhaled. Exposure to high levels of aerosol pollution has been linked to a range of health problems, including respiratory and cardiovascular diseases, cancer, and premature death.

List and briefly describe the chemical sequence of events in the fight-or-flight response to a threatening situation from the binding of epinephrine at the receptor site to readiness for another situation.
Answer:
Binding taking place at the receptor site
G protein activates in the cell membrane
Conversion of GDP → GTP
Activation of adenylate cycles
Cyclic production of AMP → ADP
Initiation of the desired reaction in regard to the original message
Cyclic restoration of AMP → ATP
Explanation:
The description of the mechanism:
Right off the bat, epinephrine attaches to a molecule called a receptor (beta-adrenergic protein).
G protein, which is found on the inner side of the plasma membrane, is activated when epinephrine binds to it.
The GDP-carrying Alpha subunit of G protein is isolated during activation. After that, the GDP is translated to GTP.
Adenylate cyclase is then activated by GTP.
The only enzyme that can catalyze the transformation of ATP to CAMP is adenylate cyclase (Cyclic adenosine monophosphate). As a result, the CAMP molecule (secondary messenger) is produced.
CAMP stimulates protein kinase A, and the cycle repeats till the glycogen phosphorylase enzyme is triggered.
After that, the cyclic amp is brought back and restored.

Maintaining high global biodiversity is important to provide ecosystem services to humans. Describe one cultural ecosystem service provided by diverse ecosystems.
Answer:
Ecosystem services of provision or supply
Explanation:
Ecosystem services
When talking about ecosystem services, we are referring to the benefits that ecosystems provide us. There are four types of ecosystem services:
Provision or supply:These are the products obtained by nature to be used or consumed, directly or with previous processing. Among them, we might mention food, clear freshwater, fertile soils, geotic materials (such as salt), raw materials (that can be used for clothing, construction), renewable fuels, biochemical compounds, pharmacological/medicinal resources, among others. Provisioning service has an impact on the economy, as many of these products are used to commercialize.
Regulation:Refers to ecological processes that improve life. Among others, we might mention climate regulation, CO² absorption, water purification, air purification, erosion control, natural disaster avoidance such as flooding, soil fertility maintenance, waste recycling, pests/plagues control, etc.
Cultural:Refers to not the material benefits. Ecosystems also provide a recreational place or area to spend time, to learn, provide a spiritual/religious space, are a source of inspiration. Ecosystems are considered to be cultural patrimony. Ecosystems are the source of scientific knowledge.
Support:Involves ecological processes needed for the production of the other three previously mentioned services. There are five different support services:
→ Soil formation
→ Photosynthesis
→ Primary production
→ Nutrients cycles
→ Water cycle
Under certain circumstances, regulation services can also be considered support services.
Support service affects human beings indirectly, or direct but causing an effect in a long-term period.
g Cells called ________ influence development by controlling the fate of other cells in their local environment
Answer:
Neighboring Cells
Explanation:
Neighboring Cells are known to be the type of cells that influence development by controlling the fate of other cells in their local environment.
Typically Neighboring cells through the process often referred to as Induction simply influence the development of other cells nearby or in their local environment. This process of cell influence is either by direct cell-cell contact or through the release of practice chemical signals.
Hence, in this case, the correct answer is "Neighboring Cells."

A stem cell that has the potential to differentiate into any cell derived from either the endoderm, ectoderm, or mesoderm lineage or into extraembryonic tissues, such as the placenta, has the property of being:
Answer:
Totipotential.
Explanation:
There are different cell potencies. A totipotent cell is a stem cell that can divide itself and differentiate in any cell that the organism needs. That is to say, endodermal cells, ectodermal cells, mesodermal cells, or extra-embryonic tissues. As cells differentiate themselves, they can gradually lose their potential. The cell's category that follows is pluripotent cells. These are stem cells that can only differentiate into ectoderm cells, endoderm cells, or mesoderm cells. Then we have multipotent cells, which differentiate into tissue cells. The next category is oligopotent cells. They give a limited number of specific cells, and lastly unipotent cells, only differentiate in one type of cell.

Suppose we have one true-breeding strain of tomato that produces red fruit. Suppose we also have a true-breeding strain of tomato that produces yellow fruit. We KNOW that a single gene is responsible for fruit color, and that the red allele is dominant to the yellow allele. If you make an F2 cross, what proportion of those fruits would you expect to be yellow
Answer:
1/4 or 25%
Explanation:
Let us assume that the fruit color trait in the tomato is represented by R and r. The dominant color red would be represented by R while the recessive color yellow would r.
If a true-breeding red fruit tomato (RR) is crossed with a true-breeding yellow fruit tomato (rr), the F1 would be thus:
RR x rr
Rr Rr Rr Rr
Since R is dominant over r, all the F1 offspring would produce red fruits with the genotype Rr.
At F2:
Rr x Rr
RR Rr Rr rr
RR and Rr = red
rr = yellow
Hence, the proportion of the F2 offspring expected to be yellow would be 1/4 or 25%.
A biologist grows bacterial cultures to see if there is a relationship between time and growth rate. Here are the data. Which hypothesis test would you use to see if there a relationship between growth rates and time
Answer:
Direct relationship.
Explanation:
There is direct relationship between growth rates and time which means growth rate of organism increases with the passage of time. Direct relationship means if one increases the other automatically increases and if one decreases, the other also decreases. The growth of bacteria becomes double when more time passes and vice versa. After every 20 minutes, the population of bacteria becomes double.

a species with a fast reproduction rate and lots of genetic variation living in a changing environment
a species with a fast reproduction rate and lots of genetic variation living in a stable environment
a species with a slow reproduction rate and very little genetic variation living in a changing environment
a species with a slow reproduction rate and very little genetic variation living in a stable environment
Extinction of the species refers to the death of the total species from the planet. The species with a slow reproduction rate and little hereditable variability habiting changing conditions will extinct first.
What factors influences the extinction rate?Many biological factors affect the survival of the organism as they play the most crucial role in the life and death of the species. The organism's reproduction rate, genetic modification and variability affect the survival of the organism.
The species that have a high rate of reproduction and high genetic variation can survive and continue their lineage when the surrounding habitat or the environment is altered or modified as they have better traits and characters.
The species in a changing environment with slow reproducing capability and very less genetic modification and variation will reduce the survival and adaptation chances of the organism and are more likely to go extinct first compared to the other organisms.
Therefore, option c, slow reproduction and less genetic variation in the species will go extinct first.

A group of researchers wants to determine the most effective antibiotic for killing the disease causing bacteria E. coli. They select 5 different antibiotics and determine how many cells were killed at the end of the experiment. The dependent variable in this experiment would be
Answer:
Number of cells killed at the end of the experiment
Explanation:
In research, the dependent variable is one whose value is dependent on another variable - a variable that is supplied by the researcher during the course of the experiment which is also known as the independent variable.
In this case, since the main objective of the research was to determine the most effective antibiotic against the E. coli, the variable that is supplied by the researcher (the independent variable) is, therefore, the different antibiotics while the variable whose value varies based on which of the antibiotics is introduced is the number of dead bacterial cells.
Therefore, the dependent variable is the number of cells killed by each antibiotic.
