Which term do biologist use to describe the number of individuals a species requires to reproduce successfully and prevent it from going extinct
Minimum viable population is the term that biologists use to describe the number of individuals a species requires to reproduce successfully and prevent it from going extinct. Minimum viable population is the minimum number of discrete organism required to reproduce between these organisms in the species and maintain that species from going extinct.
If the minimum viable population is maintained, then the species is capable of reproducing but has to compete with other organism when the limiting factor plays its role.

Barnacles and whales have a commensalistic relationship in which barnacles benefit. What would most likely happen to the whale population if the barnacle population decreased?
Answer:
There will be no impact on the whale’s population.
Explanation:
Barnacles and whales have a commensalistic relationship which is a kind of symbiotic relationship. In this kind of symbiotic relationship, two species live in association with each other where one species gets the benefit of this relationship while the other is neither harmed nor benefited.
In the case of barnacles and whales, barnacles are the species which gets benefited from this relationship as they attach to the belly or back of a whale’s body and then feed on the microorganisms while whales are neither befitted nor harmed by this association. Thus, if barnacles population decreases there would be no impact on the whale’s population.

A shift in climate changes a forested area with little annual snowfall to an area with snowfall most of the year. Natural selection would most likely favor a rabbit with which adaptation
A) increased body fat
B) more powerful legs fur burrowing
C) large ears to release body heat
D) dark coat color
A) increased body fat because they will be adapting to keeping there self warm during the snowfall
Final answer:
In a colder climate with more snowfall, natural selection would favor rabbits with a white coat color, providing camouflage against predators in the snowy environment. The correct answer from the given options is A) increased body fat.
Explanation:
The student's question relates to how a shift in climate to a colder environment with more annual snowfall would affect the natural selection of rabbits. In such conditions, natural selection would most likely favor a rabbit with the adaptation that increases its survivability in a snowy environment.
A rabbit with increased body fat or thicker fur would have better insulation against the cold, much like polar bears do. However, considering the specific adaptation to snowy environments, the most advantageous trait would be a white coat color, as it offers camouflage against the snow. This makes it harder for predators to spot the rabbit, increasing its chances of survival, and thus it can pass this beneficial trait onto its offspring over time.
Tsunamis are _____.
waves that are produced by tidal forces
waves that cannot cause damage on land
often generated by movements of the ocean floor
also known as tidal waves
Answer:
often generated by movements of the ocean floor
Explanation:
The tsunamis are the most devastating waves that occur on our planet. They are enormous and have great power, and once they reach the coastline they continue into the land and destroy pretty much everything on their way. These waves are mostly generated by movements, disturbances on the ocean floor. They occur at places where there's subduction zones. When an adjustment occurs between the crust of the plates, it creates an earthquake. That adjustment of the crust also creates gaps, through which the water is sucked in, and than as the crust continues with the adjusting and shuts the gap, the water is pushed back with lot of force. That creates the tsunamis, enormous, high speed, very powerful waves, that are devastating for everything on their way.
Answer:
option C. often generated by movements of the ocean floor

what are the two types of eukaryotic cells
Answer:
There are two types of cell, prokaryotic (bacteria) and eukaryotic (animal, plant, fungi and protoctista (unicellular organisms)). Prokaryotes have no nucleolus – the DNA is in the cytoplasm, and it can from small circular strands of DNA called plasmids. Eukaryotic cells all have their DNA enclosed in a nucleus.
Explanation:
Answer:
There are four types of eukaryotes: animals, plants, fungi, and protists. Protists are a group of organisms defined as being eukaryotic but not animals, plants, or fungi; this group includes protozoa, slime molds, and some algae. Protists and fungi are usually unicellular, while animals and plants are multicellular.

what is the result of the fertilization of an egg?
"The result of fertilization is a cell (zygote) capable of undergoing cell division to form a new individual. The fusion of two gametes initiates several reactions in the egg. ... The most important result of fertilization is egg activation, which allows the egg to undergo cell division."
The result of the fertilization of an egg is the formation of a zygote.
Fertilization is the process by which a sperm cell from the male combines with an egg cell from the female, resulting in the fusion of their genetic material. This fusion forms a single cell called a zygote, which contains the complete set of chromosomes (half from the father and half from the mother) that will eventually develop into a new individual.
The zygote undergoes rapid cell divisions through the process of mitosis, leading to the formation of an embryo, which eventually develops into a fetus and, ultimately, a new organism. Fertilization is a crucial step in s.e.x.u.a.l reproduction and the beginning of the life cycle of most multicellular organisms.

A change in the allele frequency of a population over time is called
Evolution is the change in allele frequency of a population over time.
Explanation:Evolution, in the context of biology and population genetics, refers to the change in allele frequencies within a population over successive generations. This change is a fundamental process that underlies the diversity of life on Earth.
Specifically, evolution is defined as a change in the frequency of alleles, which are different versions of a gene, within a population. This change reflects how the proportion of a particular allele within the population shifts relative to all the other alleles of the same gene that are present. These shifts in allele frequencies can occur due to various mechanisms, including natural selection, genetic drift, mutation, migration, and more.
Understanding the dynamics of allele frequency changes over time is central to the study of evolution and how species adapt to their environments and diversify.

How is the density of ocean water affected by temperature and water?
Answer:
There are two main factors that make ocean water more or less dense than about 1027 kg/m3: the temperature of the water and the salinity of the water. Ocean water gets more dense as temperature goes down. So, the colder the water, the more dense it is. Increasing salinity also increases the density of sea water.
Density can be affected by temperature and water in the following way: the warmer the water, the more space it takes up, and the lower its density.
What is density of water?Density is a unique feature of water. Water in a solid state (ice) is less dense than liquid form (water).
The higher the temperature of a water body, the lower the density of the water while the lower the temperature of the water, the higher the density.
Therefore, it can be said that the warmer the water, the more space it takes up, and the lower its density.

Sulfur dioxide is released into the air but ends up in lakes and streams as acid rain. Based on your knowledge of the water cycle, explain how this happens.
As water evapo-transpires into the atmosphere from the biosphere and hydrosphere, it cools and condenses. The water droplets in the atmosphere dissolve the sulfur dioxide molecules in the atmosphere forming sulphuric acid;
SO2(g) + H2O(l) --> H2SO3(aq)
The precipitation will, therefore, have a low pH because it is acidic. The runoff from the precipitation end up in rivers and ultimately in lakes.
Answer:
When human beings burn fossil fuels they release, sulfur dioxide, nitrogen oxides into the environment.
Those air pollutants release in the atmosphere reacts with water, oxygen and some other gases to form nitric acid and sulfuric acid.
With the help of wind the substances are spread to hundreds of miles. When the acid rain reaches the earth, it flows through lakes and other ways to enter the water system.
Plants can reproduce
A. constantly. B. only by cutting or budding. C. sexually and asexually. D. only using pollination.
Answer: C. sexually and asexually.
Explanation:
Plants are the eukaryotic organisms which can reproduce by asexual as well as sexual modes of reproduction. In asexual reproduction the plant reproduce by vegetative propagation in which a part of a plant gives the birth to numerous plantlets. In sexual reproduction the plant reproduce by fertilization of male and female gametes that are pollen and eggs to form seeds. These seeds germinate to give birth to new plants.
What factor contributed to the near extinction of the sea otter?
Answer: oil spills, shark attacks, conflict with humans, Pollution and habitat degration.
Explanation: all of these almost cause the sea otter population to die out completely hope this helps u out :)
The near extinction of sea otters was mainly due to increased predation by killer whales, which shifted their diet because of overfishing, habitat loss, and climate changes that affected their usual prey. Over-hunting history and subsequent ecological impacts like kelp forest destruction also played a role in the sea otters' decline.
The factor that contributed to the near extinction of the sea otter was a complex chain of ecological interactions, which included increased predation from killer whales. This shift in the whale's diet occurred as their preferred prey, Stellar sea lions and Harbor seals, declined due to overfishing of their food sources, higher ocean temperatures, and habitat loss. The reduction in sea otter populations caused a ripple effect, leading to the overpopulation of sea urchins and the subsequent destruction of kelp beds, which are essential for marine biodiversity.
Another significant factor was over-hunting of sea otters during the 18th and 19th centuries, which drastically reduced their numbers. This loss of a key predator in the ecosystem allowed sea urchin numbers to increase uncontrollably, resulting in the depletion of the kelp forests. It was the legal protection of sea otters in the 20th century that facilitated partial recovery of the ecosystem.
Furthermore, climate changes such as periods of glaciation followed by warming, as well as speculative causes like gamma-ray bursts from supernovae, have been suggested as contributing factors to historical extinction events related to marine species, illustrating the complexity of ecosystem changes and their impact on species like the sea otter.
The diploid chromosomal number of a cat is 38. If one of the homologous chromosome pairs does not separate during Meiosis I, how many chromosomes can be found in the gametes?
Answer:
25 and 21
Explanation:
if a homologous pair does not separate, then the homologous pair (when the spindle fibers are dragging it over to the other pole), then that chromosomes DNA will be the exact same as the paternal and maternals' DNA. During Meiosis I, there is the stage where the homologous pairs are lined up and pulled apart (where an exchange tends to happen), but if there pair doesn't mix, then the exact same DNA is duplicated, and thus, the same traits can be found in the daughter cell. If you are talking about an entire homologous pair being pulled over to one side of the nucleus, depriving the other side of a chromosomal pair, the daughter cells would then have 21 chromosomes, and the other one would have 25 chromosomes. The gametes, similarly, would have 21 chromosomes and 25 chromosomes.
25 and 21 chromosomes can be found in the gametes.
How many chromosomes can be found in the gametes?If the homologous pair does not separate, then the homologous pair when the spindle fibers are pulling it to the other pole will have the same chromosome DNA as the paternal and maternal DNA.
Therefore, during meiosis I, when there is a phase where the homologous pairs which line up and separate are where an exchange occurs, but if the pair does not match, the exact same DNA is replicated, so, the same characteristics can be found in the daughter cell.
If we are talking about a complete homologous pair on one side of the nucleus, while a chromosomal pair is being deprived on the other side, then the daughter cells will have 21 chromosomes, and the other will have 25 chromosomes. The gametes, similarly, would have 21 chromosomes and 25 chromosomes.
Thus, 25 and 21 chromosomes can be found in the gametes.

How does temperature affect electrical resistance?
A. As temperature increases, electrical resistance decreases.
B. Temperature and electrical resistance are unrelated.
C. As temperature increases to approximately water’s boiling point, electrical resistance decreases. Beyond this, it increases.
D. As temperature falls, electrical resistance decreases.
Answer:
Temperature affects metal in numerous ways. A higher temperature increases the electrical resistance of a metal, and a lower temperature reduces it. Heated metal undergoes thermal expansion and increases in volume. so the answer is C
Electrical resistance typically increases with increased temperature in conductors due to increased atomic vibrations that cause more electron collisions, thus increasing resistivity. Conversely, in semiconductors, resistance typically decreases with increased temperature.
The correct answer is that electrical resistance generally increases with an increase in temperature for conductors. This is because, as temperature rises, atoms in a conductor vibrate more rapidly and over larger distances. This increased atomic vibration causes more collisions for electrons moving through the material, thereby increasing resistivity. For most conducting metals, this effect results in an increase in resistance with temperature. The relationship can often be modeled linearly for small temperature changes, using a temperature coefficient in the resistivity equation: (ρ = ρο (1 +αΔΤ)), where ρο is the original resistivity, α is the temperature coefficient of resistivity, and ΔΤ is the change in temperature. For semiconductors, however, the situation is different. As temperature increases, their resistivity decreases because thermal agitation increases the number of free charges, making them better conductors at higher temperatures.
