Answer:
The answer is D
Explanation: This is because fungus are Eukaryotic unlike bacteria.
Answer:
The correct answer will be option D.
Explanation:
Fungal infection are the infections caused by the fungi which are less common than infection caused by bacteria.
Fungi attack animals by direct colonizing and destroying the tissues and result in mycosis. Many fungal infections occur on the animal's skin.
Although rare, they are very difficult to treat as they are closely related to eukaryotic organisms and the compound that kill the fungi also harms the eukaryotic animal host. Additionally, antibiotics target only prokaryotic cells and not eukaryotic organisms. So, this limits the medical treatments that can be used against them.
thus, option D is the correct answer.
in general, characteristics that help an organism survive and reproduce become more common in a population over time. what mechanism of evolution cause this change?
Answer:
Natural selection.
Explanation:
Natural selection means that those with good phenotypes are more likely to survive and reproduce. On the other side of the same coin, organisms with less beneficial characteristics are less likely to survive. Because of this, they can't pass their genetic information down, making it less common, and vice versa.
Natural selection is characteristics that help an organism survive and reproduce become more common in a population over time.
Who proposed the theory of natural selection?
The theory of natural selection was explored by 19th-century naturalist Charles Darwin. Natural selection explains how genetic traits of a species may change over time. This may lead to speciation, the formation of a distinct new species

1. Explain how an ice cube left out on a counter becomes a small puddle of water.
Final answer:
An ice cube left on a counter melts into water due to heat transfer from the surrounding environment. This causes the water molecules within the ice to gain energy, move faster, break their bonds, and ultimately change from a solid to a liquid state.
Explanation:
When an ice cube is left out on a counter, it turns into a puddle of water through the process of melting. This occurs because heat is transferred from the surrounding environment, such as the warmer air in the room or the heat from the counter, to the ice cube. As the ice absorbs heat, the water molecules gain energy and begin to move faster, breaking the hydrogen bonds holding them together in the solid structure of the ice.
The transfer of heat causes the ice cube (H₂O(s)) to undergo a physical change to become liquid water (H₂O(l)), as represented by the thermochemical equation: heat + H₂O(s) → H₂O(l). The energy transfer increases the entropy of the system, as the water molecules in the liquid state are more disordered than when they were in the solid state.
Even if the room temperature is below the freezing point, an ice cube can still transform into water due to the phenomenon of sublimation, where the solid ice directly converts into water vapor without becoming liquid first. However, this process is very slow and isn't the primary method of transition when an ice cube melts on a counter. Understanding these changes at a molecular level illustrates the fascinating properties of water and its phase transitions.
what must happen before meiosis can begin
Answer:
The correct answer is option C.
Explanation:
Before meiosis, DNA that is stacked into chromosomes must replicate. Before replication, the sex cell has two copies of each chromosome, one from mother, and one from father.
DNA replication takes place in the same manner as it does during mitosis. After the chromosome replication, the homologs are double in number, and each chromosome now has a homologous pair of chromosomes.
Thus, the correct answer is option C.
Before meiosis can begin, chromosomes must replicate.
Before meiosis can take place in a cell, such a cell must go through the interphase stage of the cell cycle.
During the interphase, the cell grows in size and volume (G1 phase) and chromosome replications occur (S phase). Thereafter, the cell synthesizes protein (G2) before being ready to undergo meiotic cell division.

What kind of erosion causes soil and rocks to fall?
A. Wave
B. Wind
C. Chemical
D. Gravity
Answer:
It's probably going to be D. Gravity
Explanation:
Because the question says "fall" it is safe to assume that gravity is the answer.
Gravity erosion is the type of erosion that causes soil and rocks to fall. This can occur through landslides, rockslides, and other slope movements influenced by factors like steepness and soil or rock type.
Explanation:The kind of erosion that causes soil and rocks to fall is D. Gravity. Gravity erosion, also known as mass wasting or slope movement, occurs when the force of gravity is strong enough to make soil, rock or debris on a slope slide down. An example might be a landslide, where soil and rock on a steep mountainside become unstable and tumble downwards, or smaller rockslides along a highway cutting. This type of erosion is interconnected with factors such as slope steepness, type of soil or rock, and the amount of water in the soil, which can add weight and decrease friction.

Explanation:
Hydrocarbon-containing natural resources burned for energy
Answer fossel fuels
Explanation:
Hydrocarbon-containing natural resources burned for energy include fossil fuels such as coal, oil (petroleum), and natural gas.
Fossil fuels are hydrocarbon-containing natural resources that have formed over millions of years from the remains of ancient plants and organisms. They are rich in carbon and hydrogen atoms and are the primary source of energy for electricity generation, transportation, industrial processes, and heating in many parts of the world.
When these fossil fuels are burned, they undergo combustion, combining with oxygen from the air to release energy in the form of heat. This energy is harnessed to produce electricity in power plants or to power engines in vehicles and machinery.
However, the burning of fossil fuels for energy also has significant environmental consequences. The combustion process releases carbon dioxide (CO₂) and other greenhouse gases into the atmosphere, contributing to the greenhouse effect and global warming. These emissions are a major driver of climate change and its associated impacts, such as rising sea levels, extreme weather events, and shifts in ecosystems.
Additionally, the burning of fossil fuels releases other pollutants into the air, including particulate matter, nitrogen oxides (NOx), sulfur dioxide (SO₂), and volatile organic compounds (VOCs). These pollutants can lead to the formation of smog and contribute to air pollution, which can have adverse effects on human health, particularly on respiratory and cardiovascular systems.
Due to the environmental concerns associated with burning fossil fuels, there is an increasing global emphasis on transitioning to renewable and cleaner energy sources, such as solar, wind, hydroelectric, and geothermal power, to reduce greenhouse gas emissions and mitigate the impacts of climate change.

A chemical reaction takes place in which erlergy is released. Arrange the reaction's characteristics in order from start to finis
lower energy of reactants
higher energy of products
higher energy of reactants
transition state
SD
lower energy of products
Answer:
lower energy of reactants lower energy of products transition state higher energy of reactants higher energy of productsExplanation:
As you may already know, a chemical reaction refers to the "mixing" of some chemical compounds called reagents, which will have the atoms rearranged among themselves, transforming them into other chemical compounds. This rearrangement of atoms is done with energy expenditure that can be perceived by the reactions that happen with temperature changes, light release, among others.
In summary, a chemical reaction occurs when energy is released, at which time the energy levels between reagents and products follow the following order:
lower energy of reactants lower energy of products transition state higher energy of reactants higher energy of productsIn an exothermic reaction, c) reactants have higher energy at the start. After reaching the transition state by absorbing activation energy, energy is released, and products have lower energy than reactants.
Reactants in an exothermic reaction c) begin higher energy of reactants . Energy is released and products have less energy than reactants after absorbing activation energy to achieve the transition state. In a chemical reaction where energy is released, this is known as an exothermic reaction. Here are the energy characteristics in sequential order:
Higher energy of reactants: Reactants start with a higher energy level.Transition state: The reactants absorb activation energy to reach the transition state or activated complex.Lower energy of products: Energy is released when new bonds form in the products, and the products have lower energy than the reactants.These steps explain the energy changes as bonds are broken and new bonds form, resulting in a net release of energy.

If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase.
Independent variable: _______
Dependent variable: _______
The independent variable is the number of sharks in a coastal region, and the dependent variable is the number of shark attacks on humans. The inverted pyramid indicates an unusual predation level, and ecological interactions are complex, involving numerous influencing factors. Human population changes will likely impact marine ecosystems and coastal morphology.
When considering the statement "If the number of sharks swimming in a coastal region increases, then the number of shark attacks on humans will also increase," the independent variable is the number of sharks swimming in a coastal region, and the dependent variable is the number of shark attacks on humans.
Biology often involves studying relationships between different factors in an ecosystem. An increase in the number of sharks could be influenced by various factors such as population growth of seals, their primary prey, which is typically represented with years on the x-axis as the independent variable and the number of seals on the y-axis as the dependent variable.
In a study showcasing the relationship between different trophic levels like sharks, their prey, and phytoplankton, an inverted pyramid is used to illustrate a top-heavy biomass distribution where higher trophic levels have larger biomass than the lower levels, which is an unusual situation and could convey to readers that there is an unusually high amount of predation in this region, affecting population dynamics.
Examining ecological interactions between two species, such as predator and prey, highlights the complexity and potential variances in population sizes. For instance, while seal deaths may increase due to predation by sharks, an increase in births could balance the population size. Thus, direct correlations may not always be straightforward, and factors like time of year or external influences can affect the apparent relationships between variables.

Answer:
TRADITIONAL CLASSIFICATION: based on similar appearance ; known as Linnaean classification
MODERN CLASSIFICATION: based on evolutionary relationships; known as Cladistics
Explanation:
The older classification systems were based on the morphological similarities between the organisms. One such classification was given by Linnaeus who classified plants based on the morphology of flowers and fruits.
On the other hand, the present day classification system lay more stress on evolutionary relationships of organisms. Cladistics is the system of classification that classifies organisms based on their common ancestry and does not take into consideration of morphological similarities.

Four locations on Earth receive sunlight at different angles. At which of the following angles will the intensity of sunlight received be the least? 90° 75° 50° 25°
Answer:
25°
Explanation:
The Intensity of sunlight is greatest when the sun is overhead, that is when the sun is directly above, thus the rays strike the surface at right angles. In this way the intensity of sunlight will be concentrated over a smaller region compared to when the rays strike the surface at a much smaller angle like 25 degree.
Answer:
25°
Explanation:
The intensity of solar reaches the earth with greater intensity when the sun is in a position that allows the sun's rays to reach the earth at right angles. This is possible when the sun is well above the earth, at a 90º angle. The farther from this angle, the lower the intensity of the sun's rays on the earth, in that house, when the sun is at 25 ° the intensity of the sunlight received will be less.
