Overfishing decreases the population of trout living in a river.
What would also decline because of the decreasing number of trout?
A mayflies that are part of the trout's diet
B. eels that compete with the trout for food
C. birds that use the trout as a source of food
D. fish that lay eggs that are eaten by the trout
Answer:
C. birds that use the trout as a source of food
Explanation:
Living organisms feed on one another in their natural environment in order to obtain energy for their various activities. According to this question, overfishing by humans decreases the population of trout living in a particular river.
This means that in that aquatic ecosystem (river), the population of organisms that feed on trout as a source of energy will also decrease. In this case, it is the birds. Hence, birds that use the trout as a source of food.
Answer:C
Explanation:
Because birds use that as a source of food.
All other things being equal, the size of a population will decrease if:
A
birthrate exceeds the death rate.
B
immigration rate exceeds emigration rate.
C
death rate exceeds birthrate
D
birthrate equals death rate
Answer:
C

Answer:
The question above is written twice, and without options attached. For comprehension, I would re-write the question with the options attached
Each of the following changes will result in increased blood flow to a tissue except
a. increased vessel diameter.
b. increased blood pressure
c. relaxation of precapillary sphincters
d. increased hematocrit
e. decreased peripheral resistance.
The correct answer is Option D (increased hematocrit)
Explanation:
An increase in vessel diameter would lower resistance, thereby increasing blood flow to the tissue.
An increase in blood pressure would increase blood flow to a tissue. This statement is true provided the blood pressure taking blood to tissue is not increased in the arteries.
The relaxation of precapillary sphincters which regulate the flow of blood through capillaries would cause increased blood flow to a tissue.
A decreased peripheral resistance, which means a decrease in resistance of the arteries to blood flow would increase blood flow to a tissue.
While increased hematocrit means increased red blood cells in the total volume of blood causing more thickened blood resulting in reduced blood flow to a tissue.

Amino acids with hydrophobic R groups are most often found in the interior of folded proteins. true false
Answer:
True.
Explanation:
Amino acids with nonpolar, hydrophobic R groups combine together inside the protein, thereby making hydrophilic amino acid that is outside to interact with the water molecules that surrond it. The hydrophobic molecules tend to avoid water by coalescing to form an oily or waxy droplet. This then make hydrophobic and amino acids to come together in the interior of proteins, which is far from the aqueous environment.
How is efficiency related to systems?
Answer:
The efficiency indicates the manner in which the inputs are used by the system. Being efficient means the system uses inputs in a `right' way. If the input-output ratio is adverse, we say that the system is inefficient though it produces the desired output.

The series of diagrams below represents a process carried out by a unicellular organism. This process is know as
Phagocytosis is a crucial mechanism by which cells engulf and absorb foreign substances. This method is how small, unicellular organisms like free-living amoebas obtain food. Thus, option B is correct.
What phagocytosis process carries by unicellular organism?Phagocytes, a type of living cell, devour or engulf other cells or particles through a process known as phagocytosis. An amoeba or other free-living single cell could make up the phagocyte, or it could be one of the body's cells, like a white blood cell.
In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes.
Therefore, Phagocytosis is a process used by some single-celled protists, such as amoebae, to absorb food particles.

Answer:
In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).
In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic. Neutrophils are small, granular leukocytes that quickly appear at the site of a wound and ingest bacteria.

BIO Quenching an MRI Magnet. Magnets carrying very large currents are used to produce the uniform, large-magnitude magnetic fields that are required for
magnetic resonance imaging (MRI). A typical MRI magnet may be a solenoid that is 2.0 m long and 1.0 m in diameter, has a self-inductance of 4.4 H, and carries a current of 750 A. A normal wire carrying that much current would dissipate a great deal of electrical power as heat, so most MRI magnets are made with coils of superconducting wire cooled by liquid helium at a temperature just under its boiling point (4.2 K). After a current is established in the wire, the power supply is disconnected and the magnet leads are shorted together through a piece of superconductor so that the current flows without resistance as long as the liquid helium keeps the magnet cold.
Under rare circumstances, a small segment of the magnet’s wire may lose its superconducting properties and develop resistance. In this segment, electrical energy is converted to thermal energy, which can boil off some of the liquid helium. More of the wire then warms up and loses its superconducting properties, thus dissipating even more energy as heat. Because the latent heat of vaporization of liquid helium is quite low (20.9 kJ/kg), once the wire begins to warm up, all of the liquid helium may boil off rapidly. This event, called a quench, can damage the magnet. Also, a large volume of helium gas is generated as the liquid helium boils off, causing an asphyxiation hazard, and the resulting rapid pressure buildup can lead to an explosion. You can see how important it is to keep the wire resistance in an MRI magnet at zero and to have devices that detect a quench and shut down the current immediately.
How many turns does this typical MRI magnet have?
(a) 1100;
(b) 3000;
(c) 4000;
(d) 22,000.
When current-carrying wire with many loops is connected across the battery, the magnetic field is created in the wire. A current-carrying wire with many loops is called a Solenoid.
What is current?The current is the stream of electrons flowing from positive terminal of the battery to the negative terminal so as to generate electricity. When the current flow through wire is bent into the shape of circle and continued making several loops. This wire form is called Solenoid.

If a man has type B blood and his sister has type A blood, which combination listed below is most likely the genotypes of their parents?
Answer:
type AB father and type O mother
hope this helps! :D
The genotypes of the parents are type AB father and type O mother.
How is the blood type of a child determined?Each parent contributes to one of the two alleles to their child. A mother with blood type O can only pass allele O to her child. A father with type AB can pass either the A or B allele to the child. So the child can either have a genotype as AO or BO giving the child either A blood group or B blood group.
There are mainly eight blood genotypes. The blood types are determined by the location of A and B antigens and the presence of a protein called Rh factor.
Individuals with type O blood have no antigens attached to the cell surface of RBCs. It contains A and B antigens in the plasma portion of the blood. O blood type is needed the most for blood transfusion and blood donations.
