Answer: The correct answer for the fill in the blank is- They try to share the same niche.
According to competitive exclusion principle, two species when present in the same area, try to compete for the same limiting resource like food. The species having better advantageous trait over the other survive and exclude the other one. In other words, the second species is either eliminated or shifts to some other niche.
This principle is also called Gause's principle.
Thus, competition occurs between two species when they try to share the same niche.
Answer:
they try to share the same niche

where are the proteins of the electron transport chain located
The proteins of the electron transport chain are located in the inner mitochondrial matrix in eukaryotic cells and in the cytoplasmic membrane in prokaryotic cells. Here they play a crucial role in the production of energy for the cell through the formation of ATP
Explanation:The proteins of the electron transport chain are located in the inner mitochondrial matrix in eukaryotic cells, and in the cytoplasmic membrane in prokaryotic cells. The electron transport chain is a series of electron carriers and ion pumps that help in the production of ATP, which is vital for cellular energy. Key components include multiple large, multi-protein complexes, one of which is cytochrome c, involved in various chemical reactions that create a proton gradient across the membrane. The location of these protein complexes on the inner mitochondrial membrane in eukaryotes enables the effective pumping of protons from the mitochondrial matrix to the intermembrane space of the mitochondria. The proteins embedded in the prokaryotic plasma membrane perform a similar function, facilitating the production of ATP through oxidative phosphorylation.

If a mother carries a recessive allele for a genetic disorder, such as cystic fibrosis, under what circumstances will her children inherit the disorder?
A. The children must be female like the mother to inherit the disorder.
B. The paternal grandfather must also carry the recessive allele.
C. The children's father must also carry the recessive allele.
D. The mother's father must also carry the recessive allele.
I think the answer is A, is that correct?? ...?
Children will inherit an autosomal recessive disorder like cystic fibrosis if both parents carry the recessive allele. The father must also be a carrier for the children to potentially inherit the disorder.
If a mother carries a recessive allele for a genetic disorder, such as cystic fibrosis, the circumstances under which her children will inherit the disorder is if the children's father must also carry the recessive allele. The correct answer to the question is C. This is because cystic fibrosis is an autosomal recessive condition, meaning that it occurs on one of the non-sex chromosomes and an individual must inherit two copies of the defective allele, one from each parent, to express the disorder. The gender of the child does not affect inheritance of autosomal recessive disorders; thus, male and female offspring have the same likelihood of inheriting the disease.
Furthermore, having a paternal grandfather or a mother's father who also carries the allele does not affect the child's chances of inheriting the condition unless the father himself is a carrier. This can be determined using a Punnett square, which can predict the probability of offspring inheriting the disorder based on parental genotypes.
What natural methods removes carbon dioxide from the atmosphere?
In which phase(s) of cellular respiration is water made
Water is made in the electron transport chain, which is the third and final phase of cellular respiration.
What is cellular respiration?Living organisms undergo respiration, which involves a sequence of chemical reactions occurring within their cells. This crucial process converts glucose and other nutrients into energy.
Within the membrane of the mitochondria there exists a chain of proteins known as the electron transport chain. This chain facilitates the transfer of electrons, from NADH and FADH2 to oxygen resulting in the release of energy.

Arteries carry oxygen-rich blood to capillaries. True or False? Arteries carry oxygen-rich blood to capillaries. - is true. ***The arteries deliver the oxygen-rich blood to the capillaries where the actual exchange of oxygen and carbon dioxide occurs. [ The capillaries then deliver the waste-rich blood to the veins for transport back to the lungs and heart. ]
The given statement is true.
The arteries are the blood vessels, which carry the oxygenated blood away from the heart. The arteries carry the oxygenated blood to the capillaries. the capillaries are highly branched thin walled blood vessels.
In the capillaries, the actual exchange of the gases between the blood and the body tissues takes place through the diffusion process. In the process of gaseous exchange, the capillaries become rich in carbon dioxide and other wastes, which they pass down to the veins and the veins carry the blood to heart.
Arteries carry oxygenated blood is a true statement.
Further Explanation:
Heart is a major central organ of the circulatory system. This helps the organism to use up the oxygen taken by the process of respiration by channeling to different organs. This process is undertaken by the help of blood vessels. Heart pumps the blood to different organs by means of blood vessels. Arteries are a type of blood vessel. The blood vessel is generally divided into three types;
a. Arteries
b. Veins
c. Capillaries
They vary in shape, size, structure and function. The blood vessel which is generally responsible to carry blood away from the heart to the body organs is artery. Artery carry oxygenated blood. This blood reaches the capillaries and the process of diffusion occurs. Diffusion is the process that brings about the gaseous exchange in the body. The waste material and other not required components are filtered and is excreted out of the body.
Thus, artery carry oxygenated blood away from the heart.

The right ventricle pumps blood to the___ while the left ventricle pumps blood to the___ .
Answer: Lungs and body
Explanation:
The right ventricle pumps blood into the lungs as it is deoxygenated blood and it needs to be oxygenated before it is circulated inside the body.
The deoxygenated blood is oxygenated and then it is circulated so that every cell of the body gets oxygen.
The left ventricle from the lungs pumps blood to the aorta that is circulated to the body.
The following graph is representative of what type of population growth?
a.
logistic
b.
exponential
c.
linear
d.
triangular
The correct answer is Logistic growth.
In logistic growth the per capita growth of organism decreases as the population size increases and it is due to the limited resources in the environment. The limited resources in the graph is known as carrying capacity(k). Logistics curve always gives a S-shaped graph. The logistic graph depends on the size of the population. Large population will require more resources and less population will require less resources and more time to reach the carrying capacity of the curve. Mostly yeast growth shows this type of graph.
Answer:
Option a. Logistic
Explanation:
We will analyze every option one by one
a. Logistic graph
Logistic graph is a typical S-shaped graph showing three curves.
Starting curve shows a less growth because less number of species.
Then a steep curve showing fast growth because of good number of species then curve showing less growth because of limited resources in the environment.
This option is the correct option.
b. Exponential graph
Exponential graph shows a steep growth in its curve so this option doesn't match the graph.
c. Linear graph
Linear graph shows a straight line so this option is not correct.
d. Triangular
Triangular graph is a three dimensional graph having three vertices. So this option is again not correct.
Therefore Option a. Logistic graph is the correct one.

Which of these is a significant effect of vascular plants? They were the first plants to colonize land. They gave rise to mosses. They help maintain ecological balance by preventing desertification.
Answer: They maintain ecological balance by preventing desertification.
Explanation:
Vascular plants are plants that have conducting tissues, phloem and xylem. These tissues are responsible for transporting water and nutrients from the soil to the ground.
Xylem is responsible for transporting water and phloem is responsible for transporting nutrients from the soil to the plants. They have leaves, stems and roots.
Vascular plants produce seeds and fruits. Because of the fruits they produced, they can be grown or can multiplied by sowing their seeds therefore enhancing their multiplications and preventing desertification. They maintain ecological balance by reproducing by seeds and multiplying.
Examples are angiosperms.
Biomes on Earth have exhibited changes throughout history that have been caused by a variety of factors. Over the past 50 years, the amount of tropical rainforest acreage found throughout the world has decreased from 14.8 billion acres to 8.6 billion acres due to deforestation. What factor is likely most responsible for the changes observed in the world’s rainforests?
Human activity is probably most responsible for the modifications witnessed in the world's rainforests.
The humans thrive in the rainforests and affect it extremely. The activities like logging have resulted in the loss of almost 137 animal and plant species each day due to deforestation. The activities of humans like the production of toxic by-products, oil spills, and mining incidents, and the continuous dumping of wastes are endangering the rainforests and the species living in there.
The humans also practice the slash and burn agriculture that then results in infertility of the soils and makes vegetation to stop growing. The lack of plants eventually results in an increase of carbon dioxide in the atmosphere, thus, causing global warming.
Enzymes can be denatured (unfolded) by what environmental factors?
Enzymes can be denatured unfolded by the environmental factors including heat or chemicals.
What are enzymes?Enzymes are proteins found in living organisms that can speed up chemical reactions while remaining unchanged at the end of the reaction.
Heat and chemicals are two factors that can denature enzymes. This is due to:
Higher temperatures distort the shape of the active site, reducing or eliminating its activity. Denatured enzymes are those that have lost their shape.These environmental factors can cause the enzyme's pH to change.As a result, for an enzyme to function properly, the external factors that influence its activities must be normal and favorable.
Thus, heat and chemicals are some factors that can denature enzyme.
