Answer: 1, 2, and 4

Explanation: I know I'm REALLY late, but maybe future people will look at this and need the actual answer. I mean, look at me now. I tried looking at this years after it was asked. Anyways, it's 1, 2, and 4 because I had the answer key

Statements 1, 2, and 5 correctly describe potential changes in the carbon cycle model. Statement 4 could also be correct depending on the specific context, while statements 6 and 7 are incorrect.

1 - Deforestation indeed results in a decrease in the carbon sink because it reduces the amount of vegetation that can absorb carbon dioxide during photosynthesis. Hence, this statement is correct.

2 - Increased use of alternative energy sources like solar and wind energy would likely reduce the amount of carbon released into the atmosphere because these sources do not involve the combustion of fossil fuels. This statement is also correct.

4 - The model would not necessarily remain the same for non-industrialized countries because they rely less on fossil fuels and more on natural resources, potentially impacting the carbon cycle differently.

5 - With global warming, it may be expected that the amount of carbon found in the ocean reservoir would change due to alterations in temperature, salinity, and circulation patterns. So, this statement could well be correct.

6 - The combustion of fossil fuels acts as a carbon source, not a sink, because it releases more carbon into the atmosphere. This statement is incorrect.

7 - Not all carbon in the atmosphere is made by humans. Much of it is natural, resulting from activities like respiration and volcanic eruptions. Hence, this statement is incorrect.

Answer:

75 %

Explanation:

If we take the genotype of both parents who are both heterozygous, the resulting cross would be:

Hh x Hh

Punnett square:

      H       h

H   HH    Hh

h   Hh     hh

As you can see thre are 3 possible genotypes and 2 phentypes:

HH      1  Cloven hooves

Hh      2  Cloven hooves

hh      1    Mule hooves

Because cloven hooves is dominant, it will be expressed even with the presence of the recessive allele.

So the probability is 3 out 4 or 75%

C. Inbreeding

Explanation:

It says that the parents' recessive gene came from the exact same lineage, meaning they are related. The continued inbreeding made the recessive gene more popular.

Answer:

C. inbreeding

Explanation:

Inbreeding is mating between the individuals which are closely related. Because of inbreeding, heterozygosity is reduced while homozygosity is increased in a population. Because of inbreeding a deleterious or recessive trait becomes more popular in a population. This condition is also known as inbreeding depression. Since the two individuals are closely related so their lineage also remains the same.

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.

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.

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.

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.

Answer:

ideal conditions with unlimited resources

Answer: Increased runoff carries fertilizers.

Explanation:

Increased runoff carries fertilizers describes the negative impact of human water use. The fertilizers are used to improve the quality of the soil by increasing the concentration of the minerals essential for the growth of the plants. The use of water in excess will remove the fertilizers from the agricultural land and will take them to the nearby water body. Hence, causing water pollution.

Increased runoff carries fertilizers describes the negative impact of human water use.

The increased runoff of water due to human activities, such as agriculture and urbanization, can carry fertilizers and other pollutants into water bodies, leading to water pollution and ecosystem degradation. Fertilizers used in agriculture contain nutrients like nitrogen and phosphorus, which, when washed into rivers and lakes by runoff, can cause excessive algae and plant growth (eutrophication).

This disrupts the balance of aquatic ecosystems, depletes oxygen levels, and harms aquatic life, ultimately negatively impacting water quality and biodiversity. Managing runoff and implementing sustainable agricultural practices are essential to minimize the negative impacts of human water use on water bodies and the environment.

"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.

The paper would appear black because it absorbs all colors of the visible light spectrum and reflects none back to the viewer's eyes.

If a piece of paper contains pigments that absorb the wavelengths of red, orange, yellow, green, blue, indigo, and violet, then it means all of the visible wavelengths of white light are absorbed. According to the principles of color and light, when an object absorbs all colors and does not reflect any, it will appear black to the human eye since no wavelengths are being reflected back to be detected.

Let's consider some examples to further clarify this concept. When white light shines on a yellow paper, yellow is reflected and the paper appears yellow. However, if the paper absorbed all colors of the spectrum, no light would be reflected and the paper would appear black. Similarly, if yellow light shines on a white paper, the paper would still appear yellow because white paper reflects all colors and the yellow light will be predominant. With complementary colors, such as red and green lights shining on a white paper, the combination would result in the paper appearing yellow because these two colors of light mix to create yellow on a white surface.

Hope this helped and I hope I answered in time!

~ Destiny ^_^

Final answer:

The structure of Earth's crust is such that there are high plateaus for continents and deep ocean basins, contributing to why little of Earth’s surface is far above sea levels. Geological processes such as plate tectonics have shaped mountains and plains mainly on continents, which cover less of Earth's surface compared to oceans. The distribution of mass and elevation is also influenced by gravitational variations.

Explanation:

So little of Earth's surface is found far above sea levels because of the way our planet's crust is structured. The surface of the Earth consists of high plateaus, which make up the continents, averaging around 2,750 feet (840 meters) above sea level, and the ocean basins, averaging 12,100 feet (3,700 meters) below sea level. The continents and their submerged continental shelves would appear as gigantic plateaus with steep slopes down to the deep ocean basins if you looked at Earth with the water removed.

Various geological processes such as plate tectonics and erosion contribute to the formation of Earth's topography. Mountains, canyons, and plains are shaped by these forces and are found mainly on continents, which cover a smaller portion of Earth's surface. In contrast, the vast ocean basins take up the majority of the surface area, leading to the fact that much less land exists far above sea level. Furthermore, the mass and relative impact of Earth's materials influence the gravitational pull at different points on the planet's surface, contributing to the differing elevations.

Phenotype

Explanation:

Final answer:

Zebra stripes are an example of a phenotype, the observable characteristic, which is determined by the zebra's genetic makeup or genotype. The genotype is the set of genes responsible for a trait, while the phenotype is the physical expression of that trait.

Explanation:

The question of whether zebra stripes are a genotype or a phenotype deals with fundamental concepts of genetics. In essence, a genotype is the set of genes in our DNA which is responsible for a particular trait, while a phenotype is the physical expression, or characteristics, of that trait. Zebra stripes are an example of a phenotype because they are the visible expression of the genetic information contained within the zebra's DNA. Genotypes determine what traits are possible, and the environment can influence the expression of these traits, resulting in the observed phenotype.

Another interesting aspect involves the inherited nature of these stripes. The specific pattern of stripes a zebra has is determined by its genetic makeup or genotype, but the stripes we see are its phenotype. It's worth noting that while genotypes can influence phenotypes directly, environmental factors can also impact the expression of a phenotype, albeit this is more relevant to other traits than to the fixed genetic patterns such as zebra stripes.

Answer:D

Explanation:

Because the plant would get alot of light

The plant needs carbon dioxide to live and moderate temp because its not to hot and not to cold

Answer:

D. High intensity of light, high levels of carbon dioxide, moderate temperature level​

Explanation:

The rate at which photosynthesis occurs, or whether it can occur at all,  is highly dependent on the environment of the photosynthetic organism.  Three of the most important determinants of the rate of photosynthesis  are as follows:

1.  Light intensity

2. Amount of carbon dioxide present

3. Temperature

1. Light intensity is important. As the intensity of light increases, the rate of  photosynthesis will gradually increase as well. The photosynthetic rate  will continue increasing in relation to the intensity of light until it reaches  a peak. Once the photosynthetic rate peaks, photosynthesis can't go  any faster regardless of any increase in the intensity of light. If the  intensity of light decreases, photosynthesis will also decrease.

2. The amount of carbon dioxide present can also influence the rate of  photosynthesis. Like the relationship between light intensity and  photosynthetic rate, more carbon dioxide in the environment allows for a  faster rate of photosynthesis. As the amount of carbon dioxide  increases, the photosynthetic rate increases as well. Once the rate of  photosynthesis reaches its peak, however, further increases in carbon  dioxide levels are irrelevant, as photosynthesis can't proceed any faster.  

3. Temperature is also an important factor in photosynthetic rate.  Photosynthesis proceeds faster at higher temperatures. However, if the  temperature becomes too high, the rate of photosynthesis will decline  steeply.

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.
