If there will be changes on trophic levels, what will be the effects on the ecosystem?
Answer:
It can significantly alter the homeostasis of the ecosystem
Explanation:
The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.

6. In general, as both the force and velocity of impact increase, what happens to the diameter of
the resulting blood droplets?
Answer: depending on viscosity, mass and velocity of impact, if droplet integrity is maintained, as velocity increases, diameter will increase from
Approximately d*sqrt(2) to 2*sqrt(d^3/6a) where d is original diameter and a is thickness when the droplet flattens into a disc.
Explanation:
This applies generally to any liquid droplet, which by inference falls and impacts a solid surface. The impact force is mgh where m= mass, g= acceleration due to gravity, h= initial height.
A liquid droplet deforms on impact. Assume the drop is sperical, then the deformation distance, d= diameter of the droplet then the average impact force = mgh/d.
The droplet may spread, splash or bounce, depending on viscosity and force, which depends on mass and velocity immediately before impact.
All than can be said is that if the droplet maintains integrity it could achieve the shape of half a highly flattened oblate spheroid. Approximating this with a flattened disc of thickness a, and an original volume of 4/3pi(d/2)^3, the volume as a disc =a*pi*r^2 so the horizontal diameter = 2*sqrt(d^3/6a)
It is not really possible from the available data to determine whether the droplet would remain its integrity, but at sufficiently low force/velocity, the droplet could retain a near-hemispherical shape, giving a horizontal diameter of the hemisphere = d*sqrt(2)
As velocity increases, if integrity is maintained, the diameter will increase from the second approximation to the first

In Labrador retrievers, the allele for black coat color (B) is dominant to the allele for brown coat color (b). However, if a lab has two copies of the recessive allele for a pigment-depositing gene (e), it can only have yellow coat color. In a cross of two doubly heterozygous black labs (BbEe x BbEe), what fraction of the next generation would one expect to be yellow
Answer:
4/16 or 1/4
Explanation:
This question involves two genes; one coding for coat color and the other for pigment color. The allele for black coat color (B) is dominant to the allele for brown coat color (b) while two copies of the recessive allele for a pigment-depositing gene (e) can only have yellow coat color.
In a cross between two heterozygotes (BbEe), the following gametes will be produced by each parent: BE, Be, bE and be. Using these gametes in a punnet square (see attached image), the fraction of the next generation (F2) expected to be yellow i.e. have the genotype (__ee) will be 4/16 or 1/4.
What would be the expected response to a skin injury if the involved tissue had lost the normal cell characteristic of contact inhibition
Answer:
uncontrolled excessive growth of cells in the tissue
Explanation:
Contact inhibition is a cellular mechanism where cell growth is arrested when adjacent cells are in contact with each other. Contact inhibition serves to arrest further cell growth beyond a monolayer, by limiting the migration and/or proliferation of cells in a tissue or organ. In consequence, contact inhibition is critical for normal cells to stop proliferating. When contact inhibition is disrupted, cells undergo uncontrolled growth, which leads to the development of cancer and tumor progression.
What causes ocean tides to reach higher up on a shore at certain times of day than at others? A. The moon's gravity and Earth's rotation B. The ocean's conveyor belt and refraction C. Earthquakes and volcanoes O D. Temperature and salinity differences
Answer:
A
Explanation:
I read about ocean tides. the Moon has an effect on the ocean which causes the ocean to bulge toward the Moon. When the Moon is in alignment with the sun the ocean bulges out more because of the added gravity. The Moon though smaller than the sun has more gravitational pull than the sun.
Long-term activation by nuclear receptors differs from the more transient membrane receptor signaling for what reason
what animal kingdoms were divided
Answer:
The scheme most often used currently divides all living organisms into five kingdoms: Monera (bacteria), Protista, Fungi, Plantae, and Animalia. This coexisted with a scheme dividing life into two main divisions: the Prokaryotae (bacteria, etc.) and the Eukaryotae (animals, plants, fungi, and protists).

You have been tracking an adult female otter who weighs 25 kg. How many kilocalories must she
consume each day to maintain her body weight? Show your work
Answer:
The correct answer is - 6250 kcal.
Explanation:
Otters are carnivorous mammals that depend on the different types of organisms for their food including snails, insects, and fishes or birds. An otter requires 250 Kcal/kg to maintain its body weight for survival so,
Given:
weight of otter = 25 kg
Requirement 250 kcal per kg
Therefore,
The daily calory consumption of otter: weight * required calories
250*25= 6250 kcalories

A patient with chronic venous insufficiency comes to the doctor's office complaining of leg pain. The physician prescribes two thigh-length gradient compression stockings, 45 mmHg each. HCPCS code(s):______-
Answer:
What class is this?
Explanation:
(Also if you look it up on gooogle there is an answer.) cannot answer this for you though.
The correct HCPCS Level II codes for two below the knee gradient compression stockings, 18-30 mmHg each, are A6530 x 2.
The HCPCS Level II code A6530 is used to report gradient compression stockings, below knee, 18-30 mmHg, each. The code is divided into two parts: the first part identifies the type of stocking (gradient compression), and the second part identifies the location of the stocking (below knee). The mmHg value indicates the level of compression.
In this case, the patient was prescribed two below the knee gradient compression stockings, 18-30 mmHg each. This means that the physician ordered two stockings, each of which is designed to provide a compression level of 18-30 mmHg.
The correct HCPCS Level II code for this prescription is A6530 x 2. The "x 2" indicates that two stockings are being ordered.

2. How is primary succession different from secondary
succession? Giveanexampleofaneventthat may lead primary
succession.
Answer:
Primary succession is basically the start of a brand new ecosystem. This is when pioneer species form and grow like lichens and some grasses. Secondary succession is when the ecosystem is already started and it's continuing to grow. During this time populations of other species begin to inhabit the ecosystem like shrubs and trees and some animals. Both of these processes take years to complete. An example of an event would be a volcanic eruption, and a wild fire.

Energy of activation ________. a. is the energy required for molecules to react with each other b. requires the use of enzymes c. allows for feedback inhibition d. acts on the products of metabolic reactions
Answer:
a. is the energy required for molecules to react with each other
Explanation:
Activation energy may be defined as the extra energy required to start a reaction and the conversion of reactants into its products. It is the energy required to energize or activate molecules or atoms to undergo a transformation or a chemical reaction.
It is necessary for all types of chemical reaction to proceed. With the help of a catalyst the reaction rate increases as the energy of activation lower for the reaction to start.
