How does carbon end up accumulating in soil carbon pools?
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.

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.

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.

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.
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."

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%.
In a eukaryotic cell in mitotic S-phase, a spontaneous DNA double-strand break occurred due to replication fork collapse. Genetic analysis indicates that the break was repaired by a non-crossover mechanism resulting in a stable genome. The DNA repair process responsible for this outcome was:
Answer: The DNA repair process was called recombination repair.
Explanation: A sister or homologous chromatide is used to generate recombination and be repaired in this sort of cases.

what are the two ways mitosis and meiosis increases genetic diversity?
Answer:
crossing over, and mutations caused during crossing over.
Explanation:
Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase I.
A weed in your garden is flowering. When you look very closely, you notice that what you thought was a single flower is actually a very tightly clustered group of tiny yellow tubular flowers. Upon further inspection, you find that each one of these tiny tubular flowers has petals, sepals, stamens, and a single carpel. What is true about this plant
Answer:
It has complete flower.
It has perfect flower.
Explanation:
The weed flower is considered as complete and perfect flower because the flower of weed has petals, sepals, stamens, and carpel and both male and female reproductive parts are present on the same flower. Complete flower is a type of flower that is built with four parts which include the sepals, petals, pistils and stamens whereas A perfect flower is a type of flower in which both male and female reproductive structures are present.

Answer:
A) It has complete flowers.
B) It has inflorescences.
C) It has perfect flowers.
Explanation:
Complete flowers are composed of four structures. From the exterior to the interior, we can name the sepals, petals, stamens, and pistils -also known as carpels-.Inflorescences are branch systems destined for the formation of flowers. They might be more or less delimitated concerning the vegetative parts. They are composed of the main axis known as rachis with bracts. Flowers emerge from the axilla of these bracts. Perfect flowers: Those carrying stamens and carpels.I NEED HELP ASAP
