What Is the Evidence for Evolution? Darwin used multiple lines of evidence to support his theory of evolution by natural selection -- fossil evidence, biogeographical evidence, and anatomical evidence.  Comparative embryology is the study of the similarities and differences in the embryos of different species. Similarities in embryos are likely to be evidence of common ancestry. All vertebrate embryos, for example, have gill slits and tails. ... In humans, the tail is reduced to the tail bone.  

Image result for Three lines of evidence that provide support for common ancestry and evolution are Similar embryology, Molecular homologies, and The Fossil Record.

Molecular similarities provide evidence for the shared ancestry of life. DNA sequence comparisons can show how different species are related. Biogeography, the study of the geographical distribution of organisms, provides information about how and when species may have evolved.

Cats having different fur colors is an example of biological variation within a species. Biological variation refers to the differences in traits or characteristics that exist within a population of organisms.

In the case of cats, there is variation in the color of their fur due to differences in the genes that control pigmentation. This variation is a natural occurrence that arises through genetic mutations and the shuffling of genetic information through sexual reproduction. Biological variation can have important implications for the survival and adaptation of species in changing environments. It can also be used to study evolutionary relationships among species and to inform conservation efforts aimed at preserving biodiversity. Cats have a thick, soft coat of fur that helps to regulate their body temperature and protect their skin.

Invasive species have the potential to extirpate native plants and animals, reduce biodiversity, compete with native creatures for limited resources, and change ecosystems. This has the potential to have significant fiscal consequences as well as basic changes to the coastal and Great Lakes ecosystems.

Rapid invasive species spread is a significant cause of world biodiversity loss. Through rivalry, predation, illness, parasitism, and habitat change, introduced species can have an impact on local species.

Invasive foreign species are the second most serious danger to biodiversity, after habitat loss, according to the World Conservation Union. Invading foreign species become predators, rivals, parasites, hybridizers, and diseases of our native and tamed plants and animals in their new habitats.

Wildlife may be impacted in a variety of ways, including reproduction and rapid dissemination.May decrease biodiversity by causing the loss of local creatures and plants. Direct risks include taking advantage of local animals and competing with them for food or other resources.

During the study of genetics and inheritance, it is important to observe the sexual cycle of fungi to determine the genetic variations within the offspring. In the 1920s, T. H. Morgan and his colleagues used fungal genetics to test the hypothesis of the existence of recombination. For instance, they observed the sexual cycle of the common bread mold, Neurospora crassa, to investigate how crossing-over occurs between homologous chromosomes during meiosis.

As a result of their investigation, Morgan and his colleagues discovered that, during meiosis, four haploid ascospores are produced within a specialized sac called an ascus. These ascospores are produced when two nuclei from two different hyphae (cells) combine and fuse together.

This fusion creates a cell with two haploid nuclei, which subsequently undergoes meiosis to create four haploid ascospores. Hence, an ascus will contain four haploid ascospores produced by a single diploid cell resulting from the fusion of two haploid cells.

The percentage of asci observed that resulted from the fusion of cells from different strains is 100%. This is because the fusion of haploid cells from different strains is essential for the production of a diploid cell that will then undergo meiosis to form four haploid ascospores.

Radial glial cells stretch between the MEDIAL and LATERAL surfaces of the developing nervous system.

Radial glial cells play a crucial role during the development of the nervous system. They act as a scaffold for neuronal migration and guide the growth of neurons. These specialized cells extend from the inner (medial) surface to the outer (lateral) surface of the developing nervous system.

The term "medial" refers to the central or middle region, while "lateral" refers to the outer or side region. In the context of radial glial cells, they span from the inner regions, such as the ventricular zone, towards the outer regions, such as the cortical plate or marginal zone. This arrangement allows radial glial cells to provide a structural framework for neurons to migrate along during brain development.

By extending from the medial to the lateral surfaces, radial glial cells facilitate the radial migration of neurons, ensuring proper organization and wiring of the developing nervous system. Their radial orientation serves as a guide for neurons to migrate from the proliferative zones to their final destinations, contributing to the establishment of the layered structure of the brain.

Answer:

Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.

Answer:

Latitude provides the location of a place north or south of the equator and is expressed by angular measurements ranging from 0° at the equator to 90° at the poles. Different latitudes on Earth receive different amounts of sunlight, and are a key factor in determining a region’s climate. For example, the higher the latitude of a given place (the farther away it is from the equator), the sharper the angle of the sun’s rays that reach it, meaning that the rays of the sun are spread across a broader area. Therefore, higher latitudes receive less heat than lower latitude areas nearer the equator.

The Earth’s axis is tilted 23.5° to the perpendicular, meaning that the amount of sunlight that a particular latitude receives changes with the seasons. From April to September, the Northern Hemisphere is tilted toward the Sun, where it receives more energy; the Southern Hemisphere receives this additional energy between October and March, when it is tilted toward the Sun.

Arctic

From 66.5N to the North Pole is the Arctic; from 66.5S to the South Pole is the Antarctic. Places within the arctic climate zones tend to be snow- or ice-covered year-round. This is despite the fact that they tend also to be exceptionally dry, sometimes receiving as little precipitation as the world’s driest deserts. Very little snow falls on these high-latitude regions, but even less melts due to the cold temperatures and scarce sunlight. The deep ice and snow that covers these regions has been built up over hundreds, indeed thousands, of years. In these regions, the Sun hovers above the horizon at midnight in the summer and never rises at all at times during the winter.

Temperate

The temperate zone is located between the arctic and tropic zones. However, ‘temperate climate’ is something of a misnomer since most regions located within the temperate climate zones experience distinct changes across four seasons. For example, in much of eastern North America – from the Ohio Valley in the United States to the southern shores of Hudson Bay in Canada – the ‘temperate’ climate can experience both arctic and tropical weather in the same year. These climate variations increase the further an area is from an ocean or another large body of water; they diminish in areas where oceans and other large bodies of water are able to influence the climate more strongly. Temperate regions are also affected by the direction of the air flow they receive. Areas in Canada, for example, have cool Arctic air passing through, while the southern United States receives warm air from the Gulf Stream.

Tropic

The tropical belt of land and sea extending around the globe on both sides of the equator – between 23.5S and 23.5N – receives the most sunlight, but it is not necessarily the hottest since it is covered extensively by oceans that use some solar energy for evaporation. This combination of high moisture and intensive solar heating results in a persistent zone of convection (the upward movement of moist, unstable air) known as a tropical low, which often results in generous cloud formation and frequent rainfall. These factors also help moderate the temperatures within this zone.

Most areas, however, are characterized by distinct sub-climates where average temperatures, precipitation, and other factors vary noticeably. Although there are different classifications of world climates, many of these sub-climates include low latitude tropical rainforest and tropical savanna; middle latitude maritime, mediterranean, and steppe; high latitude subarctic, tundra, and polar ice cap; as well as desert and highland areas.

The fungi mushroom has a type III survivorship curve to produce thousands of spores. Thus the correct answer is option (C) III.

If it weren't for their huge mushrooms, many species of fungi would be nearly completely invisible because the remainder of their tissue is concealed beneath the substrate they feed on, such as wooden logs or decomposing leaves. The majority of the ecosystems on Earth contain mushrooms, but they are more prevalent in moist locations where their fungal bodies are most suited for decaying.

A basidiocarp, a reproductive structure shared by all species of fungi in the subclass Basidiomycota, is an example. The pedestal-like structures of the fungi within the division are referred to as "basidium." They also get their popular name, club fungus, from their features.

Type III survivorship Curve

A Type III curve has a significant degree of concavity. When it comes to this form of survivorship, the survival rate is quite low in the early years of the individuals' lives and gradually rises as they get older. Once more, this suggests that their death rate is extremely high in their early years and may drop relatively in their older years. This is made up for by the fact that these creatures have a lot of progeny. The effect is that the children get relatively little parental attention. This approach taken by these people is referred to as the "r strategy."

The most important factors that lead to landslides are the declivity of the terrain and the type of soil.

Explanation:

Stony soils are more prone to landslides, especially on steep terrain and without any type of vegetation cover. During heavy rainfall, these two factors can promote landslides that cause major disasters, as water is able to drag this soil violently. To prevent this from happening and people from being harmed, NASA has developed satellites, which capture rainfall data and monitor the slope and composition of soils, being able to see in advance areas that could be landslides. In this way, it is possible to develop strategies that prevent the landslide from happening.
