Explain how wildfires help restore soil nutrients to forest ecosystems.
Answer:
Wildfire help restore soil nutrients - Wildfire kills off the soil organisms that consume soil nutrients. Wildfires restore soil nutrients by decreasing the amount of underbrush in forests that contribute to nutrient loss. Wildfires break down organic material faster than decomposition, thus renewing soil nutrients more quickly.
Explanation:
Wildfire help restore soil nutrients by eliminating soil organisms that consume soil nutrients and decomposition of materials that help to renew soil nutrients.
What is soil nutrients?
Soil nutrients are essential ingredients needed by plants for growth, they include nitrogen (N), phosphorus (P) and potassium (K).
Some factor can impact on soil nutrients thereby reducing it.

A local ecosystem includes a variety of grasses that grow on spongy soil. In spring, heavy rainfall and melted snow cover the soil in a few inches
of water. The ecosystem dries up by late summer. What term BEST describes this ecosystem?
A. pond
B. estuary
C. wetland
D. stream bed
Answer:
The correct answer is C. Wetland.
Explanation:
A wetland is a generic name for habitats located between hard ground and open water. Wetlands include, for example, wet and waterlogged shallow land, shallow lakes and seas, marshes, floodplain forests, and flowing waters.
Wetlands provide a breeding ground for many animal and plant species and can act as a buffer in flood areas and prevent severe and sudden floods. Rainfall, waters entering the catchment area, soil and ground elevation differences in the area, and water evaporation form the hydrological conditions of the wetlands. Wetlands are one of the most valuable and endangered habitats on Earth. Swamps, overgrown lakes, flood-prone areas, shallow bays, water-covered beach areas and mangrove beaches are all endangered habitats.

Which of the following bones are considered to be the MOST proximal?
metatarsals
clavicle
ulna
olecranon
Answer:
Of the group of bones mentioned, the most proximal is the clavicle, which is part of the shoulder girdle.
Explanation:
Proximal is a reference term used in anatomy to indicate the structures that are closest to the center of the body.
The bones mentioned -clavicle, olecranon, ulna and metatarsals- are related to the function of the limbs. The clavicle is the closest bone to them, located between the neck and the thorax, on each side of the midline of the body.
Regarding the other options, other bones are distal, as they move away from the center of the body. In order from less distal to more distal they are found:
Olecranon, which is a bone eminence of the ulna, in the upper limb. Ulna or cubitus, which is part of the bones of the forearm. Metatarsals are the bones that form part of the foot.Grapes growing on a vine are observed to shrink slightly during the day and increase in size at night. This is because:
a. developing fruits, such as grapes, transpire a lot of water to stay cool.
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
c. in leaves, phloem flow to growing sinks only occurs when the stomata are closed, because the transport capacity of the xylem is too small to supply water for both transpiration and phloem flow.
d. during the day, transpiration pulls on the water in the whole plant, causing the grapes to shrink slightly.
Answer:
b. photosynthesis to produce sugar occurs in the light, but respiration and, therefore, the growth of new cells occurs mostly in the dark.
Explanation:
Photosynthesis is the means by which green plants produce their foods by the use of sunlight, chlorophyll and carbon dioxide.
During the day, the grape make use of the process, photosynthesis, to get its sufficient food, thus the reason for the slight shrink. But at night, it respire well and new cells are produced. So that its size increase a bit.

Answer:
C
Explanation:
Laboratory techniques for randomly linking together amino acids typically generate an insoluble polypeptide, yet a naturally occurring polypeptide of the same length is usually soluble. Explain.
Answer:
The answer has been explained below
Explanation:
The polypeptide has a natural selection due to an optimized sequence. It folds properly. At the outside it has hydrophobic residues. Inside it has polar residues. Now the random sequence of the synthetic peptide is going to be unable to give a good direction to a folding process. This will cause aggregation of hydrophobic side chains on various molecules. Bringing about the polypeptides precipitation from solution. Polypeptides that occur naturally have have the same length when they are in aqueous solution because of amino acid side chains that are present and are large with reactive functional groups.
If two fruit flies, heterozygous for a gene that codes for eye color , were bred together and had 200 offspring , about how many would have the dominant phenotype
Answer:
75%
Explanation:
Assuming that eye color follows mendellian inheritance, two heterozygous parents would breed as follows:
Ee x Ee
Punnett sqaure
E e
E EE Ee
e Ee ee
All organisms possessing allele E will express dominant phenotype.
From two fruit flies, 75% would have the dominant phenotype.
What do you mean by phenotype?The phenotype is the set of observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes.
Phenotype refers to an individual's observable traits, such as height, eye color and blood type. A person's phenotype is determined by both their genomic makeup (genotype) and environmental factors.
Examples of phenotypes include height, wing length, and hair color. Phenotypes also include observable characteristics that can be measured in the laboratory, such as levels of hormones or blood cells.

Aristotle's ladder of nature, and the Great Chain of Being, were concepts suggesting __________.
a) life evolved on other worlds and was later transported to Earth down a celestial ladder
b) the accurate evolutionary view that all species are related, with each providing an evolutionary link (i.e. step in the ladder) to its immediate ancestor
c) the mystical teleological view that all species were created in a fixed order, from least to most perfect
d) life is a painful and purposeless experience of endless steps, but death brings release from the ladder of life
Answer:
c) the mystical teleological view that all species were created in a fixed order, from least to most perfect
Explanation:
The teleological argument states that God created all living things, this belief is also known as intelligent design or creationism. This belief might be considered to be opposed to the mechanism of natural selection proposed by Darwin to understand how species evolve, which can explain the complexity of living things. The creationism was firstly proposed by Socrates in ancient Greece. Subsequently, Plato (who was a student of Socrates) and Aristotle (who was a student of Plato) substantially enhanced the arguments of the intelligent design.

Compare transitional aquatic ecosystems. Identify two types in the organizer below and describe the environments each type combines. 9th grade Biology
Answer:
The correct answer is -
wetlands - land and water
estuaries - freshwater and salt water
Explanation:
There are three types of aquatic ecosystems that are lentic, lotic, and wetlands. Lentic ecosystems include slow-moving or non-moving water systems like pools, lakes, or ponds. The Lotic system on the other hand is aquatic systems with faster-moving water systems like the ocean or river also known as estuaries.
Wetlands are the system that has unique properties of having vegetation adapted according to the condition or situations on the water in saturated soil flood with water seasonally or permanent.

The fungus Melampsora lini causes a disease known as flax rust. Different strains of M. lini cause varying degrees of the rust disease. Conversely, different strains of flax are resistant or sensitive to the various varieties of rust. The Bombay variety of flax is resistant to M. lini-strain 22 but sensitive to M. lini-strain 24. A strain of flax called 770B is just the opposite; it is resistant to strain 24 but sensitive to strain 22. When 770B was crossed to Bombay, all F1 individuals were resistant to both strain 22 and strain 24. When F1 individuals were self-fertilized, the following data were obtained:
43 resistant to strain 22 but sensitive to strain 24
9 sensitive to strain 22 and strain 24
32 sensitive to strain 22 but resistant to strain 24
110 resistant to strain 22 and strain 24
Required:
Explain the inheritance pattern for flax resistance and sensitivity to M. lini strains.
Answer:
Explanation:
Using the Mendelian approach to solve this question, we will understand that the mendelian approach has a pattern for inherited traits.
From the data set given, the total number of the population is:
43+9+32+110 = 194
However, their ratio are being calculated as follows:
43/194 = 0.22
9/194 = 0.05
32/194 = 0.16
110/194 = 0.57
After comparison with the Mendelian's approach, we realize that these results seem to be similar to the 9:3:3:1 ratio.
i.e.
3/16 = 0.18
1/16 = 0.06
3/16 = 0.18
9/16 = 0.56
The inheritance pattern obviously dictates that the flax experiment proceeds in the pattern found in the Mendelian's Approach and the resistance of the two different strains were arbitrated by two traits.

If a cell does not go through the Sphase of the cell cycle before mitosis, what might be wrong with the daughter cells?
Answer:
Synthesis is the phase of the cell cycle in which DNA is replicated, occurring between G1 phase and G2 phase. Since accurate duplication of the genome is critical to successful cell division, the processes that occur during S-phase are tightly regulated and widely conserved.
Explanation:
If a cell has not properly copied its chromosomes or there is damage to the DNA, the CDK will not activate the S phase cyclin and the cell will not progress to the G2 phase. The cell will remain in S phase until the chromosomes are properly copied, or the cell will undergo programmed cell death.
Each step in the cell division is controlled and regulated by proteins like Cyclins. If a cell does not go through the S phase, it can not go to the G2 phase until the replication process is completed, or until it's programmed cell death.
-----------------------------------------------
As the cell passes through different steps of cell division, there are auto control mechanisms to ensure that the step was correctly performed and the cell is ready to go to the next step.
Many regulator molecules act during the different stages of the mitosis process to make it possible.
There are too many factors interacting, activating, and deactivating to pass from one stage to another.
Cyclins are proteins that regulate the whole cell cycle. There are different types of cycling, each of them acting on a different stage.
When the cell is going through one of the stages, the only cyclin in high levels is the one that is regulating that cycle.
Once that stage is over, that cyclin concentration decreases, and the following one increases.
But if any step was not correctly performed, the cell can not pass to the following one.
During the S stage of the interphase occurs the DNI replication process.
At this point, also occurs the synthesis of histones and other associated proteins.
This is the only stage where the DNI molecule is replicated.
S phase cyclins are in charge of regulating the stage of DNA replication.
If the cell does not go through the S phase, the cyclins of this stage are not activated. And if S phase cyclins are not active, the cell can not go to the G2 phase.
The cell remains in the S phase until the DNA replication process is correctly done. And if it does not occur, the cell suffer programmed cell death.
