Answer:

A. erosion of sediment by runoff

Explanation:

The formation of sinkholes involves natural processes of erosion or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion.

Answer:

A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. ... Water collects in these collapsed sections, forming sinkholes. Sinkholes also form when the roofs of caves collapse.

Answer:

Human use of land has negative impacts. Human activities contribute to the erosion and pollution of beaches. ... More of the rainwater runs off leading to increased erosion and drier soil. Deforestation of land can also lead to desertification and a loss of biodiversity.The burning of fossil fuels and the growth of animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. In turn, this drives climate change.Humans affect the quality, availability, and distribution of Earth's water through the modification of streams, lakes, and groundwater . ... The activities of humans have significantly altered the biosphere , changing or destroying natural habitats and causing the extinction of many living species.

Answer:

he special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of an adaptation. The spines on cycad leaves, keep animals from eating them.

Explanation:

Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

Answer:

%50

Explanation:

Heterozygous = 2 different alleles (Tt)

4 leaf clover = 2 recessive alleles (tt)

T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves

For a recessive trait (four leaves) to show 2 recessive alleles are needed

To find the percentage of the offspring to have four leaves a punnet square should be created

To find the percentage divide the number of four leaf offering with 4 and multiply by 100

2÷4×100=50

= 50%

Explanation:

The exoskeleton and molting

The success of arthropods derives in large part from the evolution of their unique, nonliving, organic, jointed exoskeleton (see figure), which not only functions in support but also provides protection and, with the muscle system, contributes to efficient locomotion. The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss. The procuticle consists of an outer exocuticle and an inner endocuticle. In the exocuticle there is cross-bonding of the chitin–protein chains (tanning), which provides additional strength to the skeletal material. The hardness of various parts of the exoskeleton in different arthropods is related to the thickness and degree of tanning of the exocuticle. In crustaceans, additional rigidity is achieved by having the exoskeleton impregnated with varying amounts of calcium carbonate.

Encyclopædia Britannica, Inc.

The formation of an exoskeleton required the simultaneous solution of two functional problems in the evolution of arthropods: If the animal is encased in a rigid covering, how can it grow and how can it move? The problem of growth is solved in arthropods by molting, or ecdysis, the periodic shedding of the old exoskeleton. The underlying cells release enzymes that digest the base of the old exoskeleton (much of the endocuticle) and then secrete a new exoskeleton beneath the old one. At the time of actual shedding, the old skeleton splits along specific lines characteristic of the group, and the animal pulls out of the old skeleton as from a suit of clothes. The old skeleton is usually abandoned but in some species is eaten. The new exoskeleton, which is soft and flexible, is then stretched by localized, elevated blood pressure augmented by the intake of water or air. Hardening occurs by stretching and especially by tanning within a number of hours of molting. In crustaceans, calcium carbonate is deposited into the new procuticle. (Soft-shell crabs are simply newly molted crabs.) Additional endocuticle may be added to the exoskeleton for some days or weeks following molting.

Molting is under hormonal control, and there is a long preparatory phase that precedes the process. The steroid hormone ecdysone, secreted by specific endocrine centres and circulated in the blood, is the direct initiator of molting. The actual timing of a molt, however, is regulated by other hormones and commonly by environmental factors. The interval between molts is called an instar. Because of the frequency of molts, instars are short early in life but grow longer with increasing age. Some arthropods, such as most spiders and insects, stop molting when they reach sexual maturity; others, like lobsters and crabs, molt throughout their lives. Most of the larger spiders of temperate regions, for example, molt about 10 times before reaching sexual maturity. As a result of molting, the length and volume of an arthropod display steplike increases over the life span, but internal tissue growth is continual as in other animals.

Loss of a limb is a common hazard in the life of many arthropods. Indeed, some arthropods, such as crabs, are capable of amputating an appendage if it is seized by a predator. The limb is then regenerated from a small, nipplelike rudiment formed at the site of the lost limb. The new limb develops beneath the old exoskeleton during the premolt period and then appears when the animal molts.

Haciendo almacenamiento y excavación en un área grande, mientras que los estanques son los sistemas utilizados para recolectar agua.

Explicación:

El sistema artificial que el hombre usa para recolectar agua es la construcción de un gran almacenamiento de concreto y la excavación de un gran terreno que recolecta agua de lluvia y puede ser utilizado por la gente para su uso diario, mientras que por otro lado, los estanques son el sistema natural donde el agua del la lluvia se acumula naturalmente. Esta agua es utilizada por la población que vive alrededor de ese estanque. Ambos sistemas proporcionan agua para el uso diario, como lavar, beber y cocinar, etc.

Answer:

Variation occurs in species with the genes resulting in the traits and physical characteristics that make it possible for them to be among the fittest for a number of reasons:

1. Mutation

2. Recombination and

3. Migration

Explanation:

Mutations:  A mutation is a deviation from the norm in a DNA sequence. It can be stimulated by errors during the DNA replication process which happens as the cell is dividing, or by exposure to ionizing radiation, chemicals, or viral infection (whether artificial or natural).

It is noteworthy that naturally, without any human intervention, the possibility of a spontaneous mutation is very low.

Recombination: This refers to the creation of new fusion of genes in the offspring that did not occur in the parents by the processes of crossing-over and independent assortment. Independent assortment meaning that the allele the gamete received for one gene was not influenced by the allele received for another gene.

Migration: Variation by migration here refers to the introduction of new genes from into one population by another. This could happen when a new population arrives at an existing one or when an existing one migrates to another population.

We can say for example that, genes from Americans have “migrated” into the population of African origin in America given the continuous immigration of Africans into America.

So in both populations, there are very fit species, but when their genes are mixed during cross-reproduction, variation arises.

Answer:

Not really sure about this question but what I think is,

So for example, metal..Metal has a very low specific heat capacity, but we use it pretty much in all our lifetime right? Things that have low heat capacity have very high capacity if that makes sense. Things like water and oil, they take more energy to get heat up or get hot. Its funny because its what makes our planet survivable. 70% of our planet is of course water and radiation (light and heat) from the sun strikes 70% of water. Meaning its not heating anything up so quickly. Hope this somewhat helps you out and gives you an idea on what the question is talking about :) Enjoy!

Virus-infected cells produce interferons that lead to the inhibition of viral replication and act as a nonspecific response of the immune system in fighting viral infections. Therefore, the correct statement is option D.

The immune system has two types of responses to viral infections: specific and nonspecific. Interferons are signaling molecules produced by virus-infected cells to activate antiviral defenses, such as apoptosis in infected cells. This refers to the nonspecific response of the immune system in fighting viral infections

Interferons function by alerting the immune system about the presence of a viral infection. Interferons can also stimulate the production of other immune cells, such as natural killer cells and macrophages to eliminate the infected cells.

Interferons have been also used to treat viral infections, such as hepatitis B, and are the nonspecific defenses that act as a first line of defense against viral infections.

Therefore, interferons that lead to the inhibition of viral replication are the nonspecific response of the immune system in fighting viral infections.
