Captive-bred trout reduce the fitness of wild populations, Relative fitness Wild Captive Captive Wild Wild Captive What statement best summarizes the results?A) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.B) The gene flow between hatchery-reared and wild populations is increasing the fitness of the wild populations.C) The gene flow between hatchery-reared and wild populations is neither helping nor hindering the fitness of the wild population.D) This data does not help us understand effects of gene flow on fitness.
Answer:
A) The gene flow between hatchery-reared and wild populations is leading to a decline in fitness of wild populations.
Explanation:
we have relative fitness at its greatest in trouts whose parents are wild x wild. crossing the wild with hatchery reared causes a decrease in the fitness of the troutgene flow is the exchange of genes between two different breeds. the wild is a greatly diverse breed and it is highly adaptive. while the hatchery reared is less adaptive.when these two breed less fit alleles will then be transferred to the wild
therefore option a answers the question

What foods below would test positive for starch in the presence of iodine?
Question 8 options:
a steak
a hard boiled egg
noodles, bread, or crackers
chicken
The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.
Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.
Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

How are polymers formes
Answer:
Polymers are formed by two main ways called addition and condensation polymerization. In addition, polymerization, an initiator (or catalyst) reacts with a starting monomer. The result of this initiation reaction is a monomer attached to the initiator with an unsatisfied bond

A student applies 55 N of force to a box on four types of surfaces. Each surface has a different value for Ffric-
On which surface is the student not able to move the box?
A. A
B. C
C. D
D. B
Answer:
D
Explanation:
The surface is the student not able to move the box is D.
What is force?Force is defined as an outside force that has the potential to alter how a body is moving or resting. A force is not something an object "has in it" or that it "contains." One thing experiences a force from another. The idea of a force encompasses both living and non-living things. The body can change its size, shape, and direction when force is applied. As we discovered in a previous session, forces are significant because they induce modifications to motion.
Net force is defined as all of the forces pulling on a thing combined. The net force, which is a single force, replaces the original forces' influence on the particle's motion. The top 5 words that are similar to "net force" in terms of this word similarity engine are resultant force, force, acceleration, physics, and rotation.
Thus, the surface is the student not able to move the box is D.

Energy for active transport comes from a cell’s _____________________? a. Golgi complex b. Nucleus c. Mitochondria d. Lysosomes
Energy for active transport comes from a cell’s Mitochondria. Thus, the correct option for this question is C.
What is Active transport?Active transport may be defined as a type of transport that occurs against the concentration gradient. This type of transport is generally mediated by carrier proteins. Metabolic energy is utilized in order to migrate ions or molecules against a concentration gradient.
This energy for facilitating the process of active transport is derived from mitochondria. This is because it is considered the powerhouse of the cell. The energy required for each metabolic event is provided by this cell organelle. This energy is generated by the process of cellular respiration.
Therefore, energy for active transport comes from a cell’s Mitochondria. Thus, the correct option for this question is C.

Question 28
A person who has PKU, a recessive genetic disorder,
А
inherited the allele for the trait from one parent.
B
inherited the allele for the trait from both parents.
С
is heterozygous for the trait.
ОО
D
will not pass the allele for the trait to his or her offspring.
Answer:
B
Explanation:
In order for one to have a recessive trait, both parents must carry the trait.
XX Xy= XX XX Xy Xy
Xy Xy= XX Xy Xy YY
XX XX= XX XX XX XX
yy yy= yy yy yy yy
Only the options in which both parents have the allele can pass it on. Only if there is no dominant allele will the trait be expressed, which can only be a yy recessive (since heterozygous would be dominant). Therefore, he will pass the allele on to his/her offspring.
How do heterotrophs make energy? How do autotrophs make energy?
Answer:
Heterotrophs obtain energy by eating plants and animals. Plants are autotrophs, absorbing the sun's energy through photosynthesis and making glucose. Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose.

More than 90% of plants have mycorrhizal associations with fungi. How might this association have evolved (include mechanisms)
Answer:
It is a symbiotic relationship and it evolved because of the benefits both plants and fungi derive from the association.
Explanation:
Mycorrhizal association is a symbiotic association between fungi and plants where both of the benefits from the relationship. The fungi inhabit the root system of plants which increase the ability of the plant's root system to absorb water for it own use and the fungi benefited from it by carbohydrates from plants which is produced as a result of photosynthesis.

which do all cells need in order to function?
a: oxygen
b: water
c: carbon dioxide
d: offspring
Answer:
A. Oxygen ( for animals )
B and C ( for plants )
Explanation:
Cellular nutrients come in many forms, including sugars and fats. In order to provide a cell with energy, these molecules have to pass across the cell membrane, which functions as a barrier — but not an impassable one. During cellular respiration, oxygen is needed. Carbon dioxide is the product of cellular respiration.
In the event you are referring to plants, then both water and carbon dioxide are needed for photosynthesis.
Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
What are Cells?Cells may be defined as the building blocks of living organisms. They are considered the basic structure and functional unit of life. All living beings are made up of cells.
Antony von Leeuwenhoek discovered the living cell for the very first time in 1674 with the help of an improved microscope in Pond water.
Cells require oxygen because they have the ability to break down food particles in the presence of oxygen to derive energy for metabolic activities. This process of breaking down food in the presence of oxygen is known as cellular respiration.
This is because oxygen functions as a final electron acceptor in the electron transport chain to synthesize an energy molecule known as ATP.
Therefore, Oxygen is required by all cells in order to function properly. Thus, the correct option is A.
