Answer:

yes

Explanation:

The answer is yes because there can be rocks changing or blocking the path of the water. While the water can erode the rocks over time it will take even more time to erode the other land and if the flow of the water stops the water will not be able to shape or erode the rest of the land.

Answer:

Earth's capacity

Many scientists think Earth has a maximum carrying capacity of 9 billion to 10 billion people. [How Do You Count 7 Billion People?]

One such scientist, the eminent Harvard University sociobiologist Edward O. Wilson, bases his estimate on calculations of the Earth's available resources. As Wilson pointed out in his book "The Future of Life" (Knopf, 2002), "The constraints of the biosphere are fixed."

Aside from the limited availability of freshwater, there are indeed constraints on the amount of food that Earth can produce, just as Malthus argued more than 200 years ago. Even in the case of maximum efficiency, in which all the grains grown are dedicated to feeding humans (instead of livestock, which is an inefficient way to convert plant energy into food energy), there's still a limit to how far the available quantities can stretch. "If everyone agreed to become vegetarian, leaving little or nothing for livestock, the present 1.4 billion hectares of arable land (3.5 billion acres) would support about 10 billion people," Wilson wrote.

The 3.5 billion acres would produce approximately 2 billion tons of grains annually, he explained. That's enough to feed 10 billion vegetarians, but would only feed 2.5 billion U.S. omnivores, because so much vegetation is dedicated to livestock and poultry in the United States.

So 10 billion people is the uppermost population limit where food is concerned. Because it's extremely unlikely that everyone will agree to stop eating meat, Wilson thinks the maximum carrying capacity of the Earth based on food resources will most likely fall short of 10 billion. [When Will Earth Run Out of Food?]

According to population biologist Joel Cohen of Columbia University, other environmental factors that limit the Earth's carrying capacity are the nitrogen cycle, available quantities of phosphorus, and atmospheric carbon concentrations, but there is a great amount of uncertainty in the impact of all of these factors. "In truth, no one knows when or at what level peak population will be reached," Cohen told Life's Little Mysteries.

Answer:

D. Plants, which release oxygen, live near the surface of the ocean,

where they receive large amounts of sunlight.

Explanation:

Plants are the multicellular and eukaryotic organisms which are autotrophic in nature. Autotrophic means they are able to prepare their own food in the process of photosynthesis. Stomata opens in daytime due to the presence of sunlight through which carbondioxide gas enters into the leaves through stomata and water is absorbed from the soil through roots. These two substances are the reactants of this process. When they combine with each other forming oxygen and glucose.

Answer:

Natural selection can be described as a phenomenon in which individuals of a population which are better adapted to survive in an environment are favored by nature as compared to the individuals of the population which lack better characteristics to survive in the environment.

Through natural selection, evolution occurs and the allelic frequency changes over a period of time. The process of evolution as well as change in the allelic frequencies does not occur just by a single individual, rather it is a collective effort which takes a lot of time. Hence, we say that natural selection changes the population and not a single individual.

Answer:

Its covering the Epidermis

The upper epidermis of a leaf is covered by a waxy cuticle that serves as a waterproof barrier, reducing water loss and protecting the leaf.

The upper epidermis is the top layer of the leaf that functions as a protective barrier. This layer is usually one cell thick, but can become thicker in harsh environmental conditions. The upper epidermis is covered by a waxy, waterproof cuticle, which helps to prevent water loss from the leaf due to evaporation and transpiration.

Additionally, some leaves have trichomes, which are small hairs that further aid in reducing water loss and can deter herbivores by storing toxic compounds or by physically impeding insects.

Answer:

No

Explanation:

It is not a solid and it is not inorganic.

Natural Gas is not a mineral because it does not meet the necessary criteria; it is not solid at room temperature and does not have a crystalline structure. It is a gaseous mixture mainly composed of methane and arises from biogenic or thermogenic processes.

No, natural gas is not considered a mineral. While natural gas does arise from geological processes, the definition of a mineral is a naturally occurring inorganic element or compound having an orderly internal structure and characteristic chemical composition, crystal form, and physical properties. To be classified as a mineral, a substance must be solid and stable at room temperature, which natural gas is not as it is a gaseous fossil fuel. Natural gas is mainly composed of methane (CH₄), with smaller amounts of other hydrocarbons like ethane (C₂H₆), propane (C₃H₈), and butane (C₄H₁₀), and sometimes contains impurities such as hydrogen sulfide.

As a gaseous mixture that lacks a definite crystal structure and is not solid at room temperature, natural gas does not meet the criteria for a mineral. Additionally, it is biogenic or thermogenic in origin, meaning it forms from the decay of organic matter or from the compression and heat treatment of organic material deep underground, respectively.

Chemosynthesis is a biological process that takes place in some bacteria and derives energy from the inorganic chemicals, in the absence of solar light. It involves oxidation of inorganic molecules to make organic molecules, such as glucose.

Cnidarians uses arm-like parts called tentacles to sting.

Explanation:

Animals belonging to genus Cnidaria use arm-like structures called tentacles to sting. The cnidarians tentacles are present with specialized stinging cells called cnidocytes.

These cnidocytes are responsible for the stinging action which is done by the cnidocyte organelle called the nematocysts or the stingers.

Nemotocyts contain coiled thread or barb-like or hair-like structures which fires the toxin out while stinging.

The opening or the mouth-like parts on the tentacles contain numerous cnidocytes which releases toxin when the tentacles are touched by another organism or when the cnindarian touches its prey.

Explanation:

Gravity is the cause of glacier motion; the ice slowly flows and changes in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster.

Answer:

No, they could not interbreed.

Explanation:

When a group of squirrels separate from each other and develop its unique characteristics, this is known as speciation. One type of speciation is allopatic speciation in which one squirrel's species separate into two separate groups and isolated from each other because of the physical barrier. This physical barrier can be a mountain range or waterway and makes it impossible to breed with one another. Each squirrels species develop unique genetic characteristics due to change in habitat  and genetic variations are transferred to their offspring.

Answer:

Forest land becomes developed land

Explanation

Just took the test

As the human population increases, the main change in land use involves forestland being transformed into developed land for housing, infrastructure, and farming. Natural habitats may be destroyed due to this process. Usually, urban land is not primarily converted to cropland.

As the human population increases, land use significantly changes to accommodate the growing needs. Predominantly, Forestland becomes developed land. This is primarily due to the necessity for more housing, infrastructure (like roads and schools), industrial developments, and farming land to feed the increasing population.

Due to this conversion of land, natural habitats and ecosystems are often disrupted or destroyed. Therefore, the notion that more land becomes available for preserves can sometimes be misleading since the total amount of undisturbed land globally actually shrinks as the human population grows.

Urban land may sometimes be converted into cropland, but this is not the primary trend. Typically, rural areas and forests are cleared for farming before utilizing urban lands.

Answer:

there is 30,000 chromosomes in the human body

Explanation:

An ameba is called so because of its ability to move and feed by extending pseudopodia, characteristic of organisms classified under the Amoebozoa supergroup. These organisms, which include both free-living and parasitic species, exhibit diverse adaptations such as bacterial endosymbiosis or multicellular stages in slime molds.

The unicellular organism is called an "ameba" due to its amoeboid movement and structure. Its body, often described as a blob of jelly, possesses the ability to change shape by extending and retracting pseudopodia (false feet) which allows it to move and ingest food through a process called phagocytosis. Ameba belongs to the Amoebozoa supergroup, which includes a variety of protozoans that exhibit similar amoeboid movement. The movement and feeding mechanism are facilitated by actin microfilaments within the cell that extend the cell membrane to form pseudopodia. Amebas are found in various environments and can exist as free-living organisms or parasites. The genus Entamoeba, for instance, includes species that can be harmful to humans, such as E. histolytica, the cause of amoebic dysentery.

Diverse amoebas exhibit specialized adaptations according to their habitat and lifestyle. The Gymnamoeba or lobose amoebae, including the well-known Amoeba proteus, show significant variation in size and complexity, from single to multinucleate forms. Their capability to host bacterial endosymbionts in place of mitochondria is a fascinating aspect of some amoebas, indicating a complex relationship with their environment. Another remarkable adaptation is observed in slime molds, especially cellular slime molds like Dictyostelium discoideum, which transition between unicellular and multicellular life stages, demonstrating cell differentiation and collective behavior.

The cell cycle phases in order consist of interphase (divided into G1, S, and G2 phases), followed by the mitotic phase which includes mitosis (with stages prophase, prometaphase, metaphase, anaphase, and telophase) and concludes with cytokinesis.

Phases of the Cell Cycle

The cell cycle is an ordered series of events involving cell growth and cell division that result in two new daughter cells. The cycle can be divided into two main components: interphase and the mitotic phase. Interphase itself consists of three stages:

The mitotic phase follows interphase, beginning with mitosis (karyokinesis), which includes the stages: prophase, prometaphase, metaphase, anaphase, and telophase. Finally, cytokinesis occurs, where the cell's cytoplasm is divided, concluding the cell cycle and resulting in two genetically identical daughter cells.

Answer: The concentration of the cytoplasm of red blood cells will be 0.5m.

Explanation: Red blood cells that are bathed in blood neither shrink nor swell and burst because the concentration of the surrounding blood is equal to the concentration inside the cytoplasm of the red blood cells. This means that the two solutions are isotonic. Since the two solutions are isotonic, there will not be movement of water molecules across the red blood cell membrane. Osmosis do not occur between two solutions of equal concentration, for osmosis to occur water molecules must move from a region of high water concentration to a region of low water concentration through a selectively permeable membrane.

Answer: Local recombination rate is expected to affect baseline diversity (grey dotted line). ... This mixing is called recombination, and it results from crossover events, where pairs of chromosomes swap genetic material. Evolutionary biologists have long known that recombination seems to increase genetic diversity.

Explanation: Natural selection attributes to increased genetic variation.

Answer: D). 100% of the females with red eyes, 100% of the males with white eyes.

Explanation: If XR represents the allele for red eyes and Xr represents the allele for white eye, and if the allele for red eyes is dominant and the allele for white eyes is recessive. Then the cross between the two will produce four offsprings, two females and two males. The females will be heterozygous for the trait having one dominant allele and one recessive allele XRXr while the males will have one allele for white eye and a Y chromosome XrY. Since XR is dominant, the females with genotype of XRXr will manifest red eye phenotype while the males with genotype of XrY will manifest phenotypically as white eyed because they have only one X chromosome.

Answer:

The amount of water that evaporates from earth is roughly equal to the amount that falls as precipitation.

Explanation:

In the hydrological cycle, evaporation consists of the conversion of liquid water into water vapor, which reaches the atmosphere. Once the water vapor condenses produces precipitation in the form of rain, snow or hail.

On the earth the amount of water that evaporates is proportional to the water that falls as precipitation. The mass of ocean water is substantially greater than the amount of land, so variations in the proportion of evaporated water and precipitation occur in the hydrological cycle:

This produces a certain grade of compensation in which, globally, the amount of water that evaporates from the earth is roughly equal to the amount that falls as precipitation.

Explanation:

A heterozygote advantage describes the case in which the heterozygous genotype has a higher relative fitness than either the homozygous dominant or homozygous recessive genotype. The specific case of heterozygote advantage due to a single locus is known as overdominance. Overdominance is a condition in genetics where the phenotype of the heterozygote lies outside of the phenotypical range of both homozygote parents, and heterozygous individuals have a higher fitness than homozygous individuals.

The correct phenomenon that occurs when oceanic crust collides with continental crust at a plate boundary is subduction.

When oceanic crust, which is denser and heavier, collides with continental crust, which is less dense and lighter, the oceanic crust is typically forced underneath the continental crust in a process known as subduction. This occurs at convergent plate boundaries, where two tectonic plates move towards each other.

As the oceanic crust descends into the mantle, it is subjected to increasing temperatures and pressures. This can lead to partial melting of the subducting plate, which in turn can produce magma that rises through the overlying continental crust. This magma can reach the surface to form volcanoes, or it can cool and solidify at depth to form intrusive igneous rocks.

The subduction process is also responsible for the formation of deep-sea trenches, such as the Mariana Trench, where the oceanic crust bends and begins its descent into the mantle. Additionally, the friction and heat generated by the colliding plates can lead to earthquakes and the formation of mountain ranges on the continental side of the boundary, as the crust is crumpled and uplifted.

In summary, when oceanic crust collides with continental crust, the denser oceanic crust is subducted beneath the lighter continental crust, leading to a range of geological activities including volcanic activity, earthquakes, and mountain building.
