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.

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.

Students in a science class visited four local ecosystems. The students observed the species present in each ecosystem and recorded their observations in the table.
Based on these observations, which ecosystem is likely to be the least sustainable?
A.Ecosystem 1, because it has the fewest species
B.Ecosystem 2, because it includes both aquatic and terrestrial species
C.Ecosystem 3, because it has few predators
D.Ecosystem 4, because it supports many animals
the answer is A
this is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem
This is because in ecosystem 1 there are only predators and no other species are observed. therefore predators have less food to eat thus they will die of hunger or move to another ecosystem.
What is Ecosystem?
An ecosystem is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.
Ecosystems contain biotic or living, parts, as well as abiotic factors, or nonliving parts. Biotic factors include plants, animals, and other organisms. Abiotic factors include rocks, temperature, and humidity.
Every factor in an ecosystem depends on every other factor, either directly or indirectly. A change in the temperature of an ecosystem will often affect what plants will grow there, for instance.

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.Why do thermos bottle keep cold beverages contained inside them from getting warm?
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.

Based on the data in the graph, how are cyanobacteria responsible for the rise in atmospheric oxygen? State your claim, then make sure to use evidence from biological processes and data from the graph to support your claim.
Answer:
They perform photosynthesis, releasing oxygen into the atmosphere as a by-product.
Explanation:
Around the time that cyanobacteria appear around 3.2 billion years ago, the oxygen levels rise sharply.
Cyanobacteria are photosynthetic organisms. They possess the photosynthetic pigment chlorophyll, meaning they can trap light energy and use it to power chemical reactions to synthesise glucose. They convert carbon dioxide and water into sugar, releasing oxygen into the atmosphere as a byproduct. This causes oxygen levels to rise.
Answer:
Cyanobacteria are microbes that live primarily in seawater. They are believed to have been the first organisms on Earth to perform oxygenic photosynthesis. In this process, they produce organic carbon, the building blocks of life's molecules, and release oxygen gas (O2).As oxygen photosynthesis starts,that's when the first O2 producing of cyanobacteria occurs.The graph reaches a peak at Cambrian explosion.

Distinguish between the different ways volcanoes cause damage.
Answer:
Hi! Your answer is:
The volcanic plume of an eruption is the pyroclastic flow which sends large amounts of ash and rock into the air and along the ground surrounding the volcano. When this ash and rock mixes with water it forms lahars which flows down the slopes of volcanoes like a landslide, clearing everything in its path. The rocks thrown into the air by the pyroclastic flow, tephra, fall to the ground causing damage where they strike. Toxic gases released through fumaroles can result in acid rain, air pollution and can deplete atmospheric ozone. And of course molten rock emitted from volcanoes as lava flows in streams down volcanoes destroying vegetation and property wherever it touches.
Explanation:
Volcanoes emit deadly gases, ash, lava, and rock. Volcanic eruptions kill. Floods, mudslides, power outages, drinking water poisoning, and wildfires can follow volcanic eruptions, posing health risks.
What are volcanoes?The pyroclastic flow that results after an eruption of a volcano is known as the volcanic plume. This flow transports significant quantities of ash and rock into the air and along the ground in the area surrounding the volcano. When this ash and rock combines with water, it generates lahars, which are similar to landslides and rush down the slopes of volcanoes like a river, sweeping away everything in their path.
When they hit the ground, the rocks that were thrown into the air by the pyroclastic flow, known as tephra, cause damage to the area where they land. Toxic chemicals that are emitted by fumaroles have the potential to cause acid rain, contribute to air pollution, and reduce the amount of ozone in the atmosphere.

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.
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.

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.
