Answer:
Advantage of cell walls
It protect and support the cell .
To give difinite shape for the cell.
Having cell walls surrounding cell membranes provides several advantages to plants, including structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture.
The cell wall is a rigid structure located outside the cell membrane in plant cells. It is composed primarily of cellulose, a complex carbohydrate. Here are the advantages of having cell walls:
Structural Support: Cell walls provide mechanical support to plant cells and help maintain the overall shape and structure of the plant. They allow plants to stand upright and withstand environmental forces such as wind or gravity. The cell walls of adjacent plant cells are interconnected, forming a strong network that provides stability to the plant as a whole.
Pathogen Protection: The cell wall acts as a physical barrier against pathogens such as bacteria and fungi. It prevents the entry of pathogens into the plant cells, reducing the risk of infection. Additionally, the cell wall can contain antimicrobial compounds and other defense molecules that provide further protection against pathogens.
Water Regulation: The cell wall plays a crucial role in regulating water balance within plant cells. It helps maintain turgor pressure, which is essential for cell expansion and overall plant growth. The cell wall allows water to enter and exit the cell in a controlled manner, preventing excessive water uptake or loss.
Cell Rupture Prevention: The rigid cell wall helps prevent cell rupture or bursting when the internal pressure within the cell increases. It provides strength and stability to the cell, allowing it to withstand internal pressure changes without bursting.
Overall, the presence of cell walls in plant cells offers significant advantages in terms of structural support, protection against pathogens, regulation of water balance, and prevention of cell rupture. These advantages contribute to the overall health, growth, and survival of plants in diverse environmental conditions.

The F2 generations of dihybrid crosses of Labrador retrievers are expected to produce the recessive epistatic ratio of 9 black: 3 chocolate: 4 yellow dogs. A random sample of 80 dogs was taken from F2 crosses. What is the expected number of yellow labs in the sample and what number of degrees of freedom is needed for a chi-square test of recessive epistasis

food scraps from the shark.
E)
Answer: A, E
Explanation: I took the USA Test Prep and the person above me who commented said so.
An animal engaging in commensalism is as basic as a bird building a nest in a tree. Without being considerably injured or influenced by the bird, the tree offers the bird shelter and protection. Thus option A, E is correct.
What defines about Commensalism symbiotic relationship?A symbiotic relationship known as commensalism occurs when one species benefits while the other is unaffected. Usually, one species exploits the other for something outside food. For instance, mites will cling to larger flying insects to “hitch a ride.” Hermit crabs live in the dead snails' shells.
A relationship between members of two species when one species receives food or other benefits from the other without endangering or helping the latter. Commensalism.
Therefore, A bird builds a nest in a tree and A remora attaching itself to a shark obtaining transportation, shelter, and food scraps from the shark.

Explain how temperature and amount of precipitation can affect the type of plants and animals found in the desert biome?
Answer:
A influência da vegetação sobre o clima acontece de diferentes formas, influenciando tanto no albedo quanto na umidade e nas variações de temperatura. Isso significa dizer que alterar a cobertura vegetal de um dado local é também propiciar alterações climáticas no local da intervenção e também em outras partes do planeta. A consequência de uma maior umidade do ar é a menor amplitude térmica (a diferença entre a maior e a menor temperatura), ou seja, a ocorrência de médias de temperaturas mais constantes. Isso ocorre em razão do calor específico da água, responsável por conservar o calor por mais tempo.
Explanation:
Answer: In the desert biome the temperature's are extreme. They could get to over 100 degrees. Plants and animals adapted to their environment over man centuries. The amount of precipitation a plant or animal get can effect how they grow. Plants need lots of water so the can grow and flourish and animals need it so they can live. If the don't get enough then they could die. Th plants there need to endure long-spread drought. So they need deep roots so they can soak up lots of water. animals like the coyote go out in the night. when it's cooler. they hunt lizards.

Inhibitors of the electron transport chain exert their effects through a variety of mechanisms.
____________ blocks electron transport and proton pumping via inhibition of Complex IV.
____________ blocks electron transport and proton pumping via inhibition of Complex I.
____________ blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.
Answer:
Azide and Carbon monoxide block electron transport and proton pumping via inhibition of Complex IV.
Rotenone blocks electron transport and proton pumping via inhibition of Complex I.
Atractyloside blocks electron transport and ATP synthesis by inhibiting the exchange of ATP and ADP across the inner mitochondrial membrane.
Explanation:
The mitochondrial electron transport chain is composed of different complexes integrated into the inner mitochondrial membrane, which function to generate an electrochemical proton (H+ ions) gradient that is then used to drive the synthesis of ATP, the energy coin of the cell. The mitochondrial complex I catalyzes the electron transfer from nicotinamide adenine dinucleotide (NADH) to ubiquinone and then transports H+ ions across the inner mitochondrial membrane. Moreover, the mitochondrial complex IV, also known as Cytochrome c oxidase, receives electrons via the cytochrome pathway in order to complete the reduction of oxygen (O2) into two molecules of water (H2O). Azide is a selective inhibitor of the complex IV which acts as an uncompetitive inhibitor with regards to O2, while carbon monoxide (CO) binds to the cytochrome c oxidase enzyme, thereby suppressing its activity and thus disturbing ATP synthesis. Rotenone is a potent inhibitor of the mitochondrial complex I that inhibits electron transfer from the iron-sulfur centers in the complex I to ubiquinone, thereby blocking ATP synthesis. Finally, atractyloside is a competitive inhibitor that inhibits the transport of ADP across the mitochondrial inner membrane by blocking the ADP/ATP translocator, thereby preventing ADP from entering mitochondria.

How does the population of red-tailed hawks affect the population of prairie dogs living in the meadow? How does the population of prairie dogs affect nonliving parts of the meadow, such as soil? Help, please.
Answer:
Explanation:
Red tailed hawks will often prey on prairie dogs. The hawks will eat the prairies dogs so they will lessen the population. Prairies dogs create more fertile soil, so this allows plants to germinate, or grow. This results in more food for prairie dogs and thus more food for hawks.
