The competitive exclusion principle states that two species cannot occupy the same niche. When two species compete for the same habitat and resources, the end result is that one species eliminates the other.
Explain why a trait inherited by incomplete dominance is not a blend of two alleles.
Answer:
The trait is inherited by incomplete dominance is not a blend of two alleles because both are equal and appear on the phenotype therefore it is not a blend of two alleles.
Explanation:
A trait which is inherited by Incomplete dominance is not a blend of two alleles as both the alleles show their effect as both are dominant however not completely but character appears in the phenotype of the person.
What is incomplete dominance?
Incomplete dominance results from the cross in which each of the parent is genetically unique and gives rise to progeny whose phenotype is in between the two parents. Incomplete dominance is also known as semi-dominance and partial dominance.
Incomplete dominance resembles with the idea of blending inheritance of characters, but can still be explained through Mendel's laws with some modifications. The alleles here do not exert full dominance and the offspring produced resembles a mixture of the two phenotypes of parents.

water droplets forming on the inside of a cold windshield is an example of
The forming of water droplets on the inside of a cold windshield is an example of condensation. This process happens when warm, moist air comes into contact with a cold surface and the water vapor in the air transforms into liquid water droplets.
Explanation:Water droplets forming on the inside of a cold windshield is an example of the physical process of condensation. This occurs when water vapor present in the air comes into contact with a surface that is colder than the air's dew point temperature. The warm, moist air inside the vehicle is cooled when it contacts the cold windshield, causing the water vapor in the air to transform into liquid droplets.
As another example, condensation can be seen when a glass filled with a cold beverage gets covered with water droplets. The cold glass cools the surrounding air, and if the cooled air can no longer hold all of its vapor as a gas, the excess turns into visible droplets of water on the outside of the glass. In essence, condensation is the process by which water vapor in the air is cooled enough to form liquid water.

Members of The same community always belong to The same
Final answer:
Community membership is characterized by shared norms and values that facilitate a sense of solidarity and unity within a group. The concept of 'Gemeinschaft' highlights how communal bonds are formed, transcending individual self-interest for the good of the group. Individuals often belong to multiple communities concurrently, based on various facets of their lives.
Explanation:
Members of the same community often have a shared set of values or priorities, which serves as the basis for their association. This concept, known as Gemeinschaft, describes a social group where individuals are connected through common norms due to shared experiences, physical space, or beliefs. These communities can include family, ethnic groups, religious congregations, or national communities, and they reflect a strong sense of togetherness and mutual bonds, forming a collective identity.
In these communities, such as those formed around hobbies like sports or music, age, career, or even shared geography, members are often more oriented to the will and good of the group than their own self-interest. They participate and contribute based on common mores or beliefs about appropriate behavior and responsibilities, nurturing a sense of solidarity and unity.
Ultimately, members of the same community do not always belong to just one community; they are part of multiple groups in different contexts of their lives, which can include political parties, sports teams, and various societal groups. It's their shared culture and experiences that help solidify their membership within a specific community, as they work in unity and support the collective goals of the group.

Answer:
B) open ocean
Explanation:
The open ocean ecosystems have the least available nutrients and lowest productivity. The limiting factors in an marine habitat are light and nutrients. Coastal ecosystems, estuaries and coral reefs have much higher nutrient availability and high productivity because plants are in shallow water and receive plenty of sunlight.
which of the following is not involved in controlling buoyancy in fishes
Buoyancy in fishes is regulated by the swim bladder, not by gills which are used for breathing and are not involved in controlling buoyancy.
The student asked which of the following is not involved in controlling buoyancy in fishes. Buoyancy control in bony fishes is primarily handled by a specialized structure called the swim bladder, a gas-filled organ that allows the fish to maintain its position at different water depths without expending energy swimming. The swim bladder functions by varying the amount of gas it contains, which alters the fish's buoyancy. Additionally, gills are used for breathing by drawing water over them, which are covered by a muscular flap known as the operculum. Thus, gills, while crucial for gas exchange, are not directly involved in controlling buoyancy.

if meiosis did not occur during the formation of gametes, sexual reproduction would result in
Answer:
the chromosome number would double with every generation.
Explanation:
The formation of haploid gametes occurs through a process of cell division called meiosis, which occurs in two consecutive stages called meiosis I and meiosis II.
Meiosis I is also called the reductive phase (R!), Because a diploid cell (2n) will give rise to two haploid cells (n).
In meiosis II, the two haploid cells (n) formed during the first stage (meiosis I) continue the division, giving rise, each one, to two more haploid cells (n) which will, at the end of the 2 stages, a total of four haploid cells (n). Meiosis II is called equational division (E!), Because dividing cells form daughter cells with the same number of chromosomes.
In short, if meiosis did not occur during gamete formation, there would be no reduction in chromosomes, the result of which would be that the number of chromosomes would double with each generation.
Without meiosis, sexual reproduction would produce offspring with a doubled chromosomal content every generation and lead to potentially harmful mutations and reduced genetic diversity. Meiosis ensures each gamete carries the correct number of chromosomes and enhances genetic diversity, vital for species' adaptability.
Explanation:If meiosis did not occur during the formation of gametes, sexual reproduction would result in offspring with a doubling of genetic content over generations, potentially detrimental mutations, and reduced genetic diversity. This is because, during sexual reproduction, each parent contributes one set of chromosomes to their offspring. Meiosis plays a crucial role in halving the chromosomal number, ensuring that each gamete carries the correct number of chromosomes. Therefore, it is essential for maintaining the stability of species.
Without meiosis, gametes would be produced through mitosis. This means the offspring would inherit the full set of each parent's genes, resulting in a doubling of chromosomes every generation. Besides, the absence of crossover events and independent assortment during meiosis would lead to reduced genetic diversity. This is unfavorable as genetic diversity is essential for a species' adaptability to changing environments.

what process produces usable energy in cells
Final answer:
Cellular respiration is the biological process that converts glucose into ATP, the usable form of energy for cells, involving stages such as Glycolysis and the Krebs Cycle.
Explanation:
The process that produces usable energy in cells is known as cellular respiration. This biochemical process involves a series of chemical reactions that break down glucose molecules and convert the energy stored in their chemical bonds into a form that cells can use.
The most common energy currency that cells use for this purpose is ATP (adenosine triphosphate). Cellular respiration happens in multiple stages, including Glycolysis, the Transformation of Pyruvate, the Krebs Cycle, and Oxidative Phosphorylation.
Through these stages, glucose and oxygen are transformed into carbon dioxide and water, and ATP is produced. This metabolic pathway is essential for supplying energy for all cellular activities, from muscle contraction to active transport across cell membranes.
Which property would have the greatest percentage of runoff?
A. 75% of the area is vegetation and 25% is roofed or paved
B. 25% of the area is vegetation and 75% is roofed or paved
C. 50% of the area is vegetation and 50% is roofed or paved
D. All of the above will have the same runoff
Answer: The correct option is B. 25% of the area is vegetation and 75% is roofed or paved.
Vegetation can cause precipitation and reduce runoff. Leaves and stems are used in capturing rain and prevents the rainwater to reach the ground. Dense vegetation with higher surface area under vegetation absorbs water and prevents runoff. Pavements or roofs cause the runoff water by filling the waterways as there is no vegetation for water absorption which leads to overfilled waterways and in turn cause flooding.
why doesn't asexual reproduction result in variation among offspring and parents?
There is no mating or mixing of genetics in asexual reproduction. Asexual reproduction results in a clone of the parent; the offspring has identical DNA as the parent. There is usually no variation from generation to generation in a species population that relies on asexual reproduction.
One way for an asexually reproducing species to get some diversity is through mutations at the DNA level. If there is a mistake in mitosis or the copying of the DNA, then that mistake will be passed down to the offspring, thereby possibly changing its traits. Some mutations do not change the phenotype, however, so not all mutations in asexual reproduction result in variations in the offspring.
On most ocean shorelines, the water rises slowly and covers the land twice a day. Then it slowly falls back. What is this movement called?
Final answer:
The twice-daily movement of ocean waters, known as tides, is caused by the Moon's gravitational pull on Earth, leading to two high tides and two low tides each day due to the rotation of Earth through tidal bulges.
Explanation:
The movement of water rising slowly and covering the land twice a day, then falling back is called tides.
This phenomenon is caused by the Moon's gravitational pull on Earth, which varies in different locations.
Tides are significant as they demonstrate the dynamic nature of Earth's oceans, resulting from the gravitational forces exerted by the Moon and, to a lesser extent, the Sun.
These tidal forces create two tidal bulges on opposite sides of the Earth.
As the Earth rotates, any given point on the Earth's surface experiences these bulges, leading to two high tides and two low tides every day.
This movement is crucial for coastal marine ecosystems and affects human activities such as fishing and navigation.

The answer is D. Many types of resources are unevenly distributed across the world or Some resources are plentiful only in a few areas.
both for apex just depends on which answer choices you are given
i took the test so i hope it helps
Answer: D. Many types of resources are unevenly distributed across the world.
Natural resources are those material or entity obtain from natural environment sources. Based on their origin resources can be classified into: Abiotic Resources (non- living resources like water, soil etc) and Biotic Resources (living resources like plants, animal, humans etc). Resources can be classified on the basis of their availability: renewable and non-renewable resources. Renewable resources are those which can be replenished and reproduced relatively quickly. For example, agricultural crop. Non-renewable resources are those which are produced after millions of years and they cannot be reproduced and replenished quickly. For example, fossil fuels. Resources can be classified on the basis of their distribution: Ubiquitous resources (these are abundantly present in the world example air, water, light) and Localized resources (these are only found in certain parts of the world example coal, copper, iron ore etc). Therefore, resources are found unevenly distributed across the world.
