What is the biological impact of minimum catch sizes on a population of fish? a. The population comes to be dominated by smaller, slower-growing individuals. b. Older, less productive adults are removed, improving the population’s health. c. It applies a selective pressure for larger, faster growing fish. d. The fish in the population produce more and healthier eggs to compensate.
Answer: The population comes to be dominated by smaller, slower-growing individuals
Explanation:
The minimum catch size simply refers to the shortest allowed length that is required for a caught fish. It should be noted that the minimum catch ensures sustainability with regards to the use of fish stocks and also helps in the promotion of the recovery of some fish.
Lastly, a biological impact of minimum catch sizes on a population of fish is that population comes to be dominated by smaller, slower-growing individuals.
Answer:
Explanation:
The answer is A.) The population comes to be dominated by smaller, slower-growing individuals.
Rates of extinction tend to be higher on islands than on the mainland.
O True
O False
Answer:
True.
Explanation:
In biogeography, extinction is the ending of the existence of some species or other taxonomic group. It is a normal natural phenomenon. Species are becoming extinct because the factors that keep the population small, such as diseases or predators, are increasing, because their living environment is changing drastically due to climate change, for example, or because competition is increasing.
Thus, if these species are enclosed in small and dead-end territories, such as an island, their extinction will be easier, since they will not have the possibility of migrating (except for birds) or expanding territorially.
Which of these would be an example of cultural bias in profiling?
a) Investigators are sure that their suspect is a tall male because they have found large footprints in the mud.
b) Investigators conclude that the victim allowed the suspect to enter the home, so they knew each other.
C) Investigators say that the suspect must be of a certain minority because that is who usually commits the crime in their precinct.
d) Investigators look for all the people leaving the crime scene to see if they are possible suspects.
Answer:
C) Investigators say that the suspect must be of a certain minority because that is who usually commits the crime in their precinct.
Explanation:
Cultural bias is the action where by someone holds a bias about a particular group of people or ethnicity due to the negative information which he or she had been feed with while growing up.
For example, when someone believes that, all crimes committed in America is done by African American people is a typical example of cultural bias. In the scenario given above, for the investigator to believe that, the suspect to be a certain minority rather than having an open view that it could have been anyone shows cultural bias and profiling of the investigators.
1) You can see two moths in this image, Living on the bark of trees. They
are the same species of moth; they differ in color. If the habitat of the
two moths does not change, predict what will happen to the moth
population in this area and explain why.
A)
If the habitat does not change there should be no
change in the moth population.
B)
The lighter moth population will have better chance
of survival due to camouflage. Light moths will
increase: dark moths will decrease.
C)
The population will shift to the to favor the light
moth. The light moth population will increase
because the dark moths will leave the area.
D)
As the seasons change, both moths will be hidden by
foliage growing on the trees. We would predict no
big change in the moth populations, light or dark.
The Correct answer Is B.
this is because of natural selection
hope this helps !
The lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease due to industrial melanism. Therefore, option B is correct.
What is industrial melanism?Industrial melanism is a phenomenon in which the frequency of dark-colored or melanistic individuals in a population of organisms increases as a result of environmental pollution.
This phenomenon was first observed in the 19th century in industrialized regions of England, where the population of peppered moths shifted from mostly light-colored to mostly dark-colored in response to pollution from industrial activities.
Thus, the lighter moth population will have a better chance of survival due to camouflage. Light moths will increase and dark moths will decrease. Therefore, option B is correct.

The two major sources of energy for the rock cycle are the sun, which provides energy for surface processes such as weathering, erosion, and transport, and the Earth's internal heat provides energy for processes like subduction, melting, and metamorphism. And Magma, when it is allowed to cool, it crystallizes, much the same way that ice crystals develop when water is cooled. We see this process occurring in places like Iceland, where magma erupts out of a volcano and cools on the surface of the Earth, forming a rock called basalt on the flanks of the volcano
----------------------------------------
how each source of energy causes the rock to change forms:
Over many thousands of years, energy from the Sun moves the wind and water at the Earth’s surface with enough force to break rocks apart into sand and other types of sediment. When sediment is buried and cemented together, it becomes a sedimentary rock such as sandstone or shale.
Magma is a hot liquid made of melted minerals. The minerals can form crystals when they cool. Igneous rock can form underground, where the magma cools slowly. Or, igneous rock can form above ground, where the magma cools quickly.

A population of raccoons is thought to be in Hardy-Weinberg equilibrium for a tail-length gene. The frequency of the dominant allele (long tails) is 0.8. When a certain forest was surveyed, the scientist was able to tag 25 animals, which were all long-tailed. Does the lack of short-tailed animals suggest that the population is out of Hardy-Weinberg equilibrium in this forest?
A. Yes, because the survey shows 100% AA individuals, so the short tils must have been selected against.
B. No, because you would only expect 4 of the surveyed racoons to be short-tailed, so they may have been missed by chance.
C. Yes, because 20% of the surveyed raccoons should have been short-tailed.
D. No, because you would only expect 4% of the raccoons to be short-tailed, so they may have been missed by chance.

A plant species live in an area with limited sun.Which physiology adaptation would be most useful to the plant?
Answer:
The correct answer is - large leaves.
Explanation:
Chlorophyll is the green pigment present in the chloroplast found in the plant cells that is used to make food or glucose from sunlight. These pigments are present in a high amount on the leaves of the plant.
If a plant lives in an area with limited sun then there will be a limited amount of sunlight for that plants adapt accordingly and big leaves are one of them. Big leaves have more chlorophyll and the more the pigment higher the amount of energy is trapped by the plant for food production.
Two pea plants heterozygous for the characters of pod color and pod shape are crossed. Assume that G allele stands for green pod color, g allele−for yellow pod color, I allele−for inflated pod shape, and i allele−for constricted pod shape. Complete the Punnett square for this cross.
Answer:
Please find the punnet square in the attachment section
Explanation:
This question involves two different genes; one coding for pod color and the other for pod shape. The allele for green pod color (G) is dominant over the allele for yellow pod color (g) while the allele for inflated pod shape (I) is dominant over the allele for constricted pod shape (i).
According to this question, two pea plants heterozygous for both of the characters or traits are crossed i.e. GgIi × GgIi. Each heterozygous parent will produce the following possible gametes:
GgIi - GI, Gi, gI and gi.
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
- Green, inflated pods (G_I_) = 9
- Green, constricted pods (G_ii) = 3
- Yellow, inflated pods (ggI_) = 3
- Yellow, constricted pods (ggii) = 1

A consistent response in many organisms to changing environmental temperatures is the restructuring of cellular membranes.In some fish, phosphatidylethanolamine (PE) in the liver microsomal lipid membrane contains predominantly docosahexaenoic acid, 22:6 at C-2 of the glycerol-3-phosphate backbone and then either a saturated or monounsaturated fatty acyl group at C-1. Which of the following statements are False?
a. At 10 degrees Centigrade a lower percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
Ñ. At 30 degrees Centigrade a lower percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
e. The purpose of membrane restructuring with a change in temperature is to maintain fluidity of the membrane.
Answer:
The false statements are :
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
Explanation:
The false statements are :
b. At 10 degrees Centigrade a higher percentage of PE molecules contain saturated fatty acyl groups at C-1 when compared to fish acclimatized at 30 degrees Centigrade.
d. At 30 degrees Centigrade a higher percentage of PE molecules had monounsaturated acyl groups at C-1 compared to that observed at 10 degrees Centigrade.
Reason -
When temperature decreases, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases that also decreases the fluidity of the membrane and thereby make it stiff.
When temperature increases, the proportion of unsaturated fatty acids decreases and saturated fatty acids increases that makes the cell membrane more fluidic.
So, the temperature changes restructures the membrane with respect to fluidity of membrane.
Therefore,
At 10° Celsius, at C-1 of glycerol, the proportion of unsaturated fatty acids increases and saturated fatty acids decreases.
At 30° Celsius, the proportion of unsaturated fatty acid decreases and saturated fatty acid increases.
