Algae growth produces a high concentration of oxygen on the surface, which decreases with depth. The less oxygen available in deeper strata, the fewer surviving forms of life. The correct option is C.
-----------------------------------------------------------------------------------------------------------
Available data:
Depth of Water Dissolved Oxygen Amount of Algae/sq. meter
(meters) (mg O₂ per liter) (kilogram)
1 9.2 550
5 9.0 535
10 8.5 404
15 7.0 155
20 5.5 45
25 4.2 12
According to this table,
On the surface, there is a higher amount of algae, and hence, more dissolved oxygen. As it gets deeper, algae amount decreases as well as dissolved oxygen.
If oxygen decreases with depth, it suggests that plants -oxygen producers- lack, probably due to the lack of sunlight reaching the bottom.
Other forms of life
Algae growth on the surface blocks the pass of light to the deeper strata.The lack of light in deeper strata affects plants' growth.If there are no plants in deeper areas, there is no dissolved oxygen.Since animals need oxygen, they probably can not survive in deep regions.With no oxygen, the bottom turns into an anaerobic environment, in which anaerobic bacteria can survive.
These conditions can be related to eutrophication.
Eutrophication is a biological process produced in water by an oversupply of nutrients or organic matter.
This oversupply, mainly of nitrogen or phosphorous, favors phytoplankton multiplication, especially cyanobacteria.
Cyanobacteria overgrowth leads to an enhance in primary productivity and reduces the pass of radiation to deeper strata. This fact affects biota in deeper zones.
Gradually sedimentation begins, caused by the death of some vegetable organisms that sink in the bottom.
These sediments suffer decomposition in the absence of oxygen. Anaerobic bacteria act and produce fermentation.
Phytoplankton overgrowth on the surface and fermentation process in the bottom, originate toxic compounds that can damage the animals in the water body.
Animals die, creating more sediments in the bottom where there are anaerobic conditions.
The continued increase in decomposition and fermentation produces a bad smell and toxicity.
The result of eutrophication is the stratification of the water mass:
First superficial layer, the overgrowth of blue-green algae, produces toxins and interrupts the pass of light to deeper areas. The surface then becomes warmer. The second layer might have oxygen available for the animals. In the third layer, there is no oxygen, so life is impossible for animals or plants. In the fourth layer, there are animals and plant remains in the process of sedimentation. At the bottom, there are organic matter and anaerobic bacteria in charge of decomposition and fermentation, through which they produce toxic gases and smell.Options:
A) All of the life forms in the lake can be found within the top 10 feet of water. FALSE. Depends on the conditions and the species.
B) As you increase in depth of water, plant density decreases while fish density increases. FALSE. Plant and animals density decrease, as available oxygen decrease.
C) Organisms in the lake rely on dissolved oxygen to survive. The lower the dissolved oxygen, the lower the survival rate. TRUE.
D) Plant survival is related to the amount of light (depth) but animal survival is related to the amount of oxygen available. The lower the amount of dissolved oxygen, the less animal life is present in the lake. FALSE. Light does not reach the bottom, so there are no plants there. Plants also depend on oxygen, not only animals.

Tropical rainforests have the greatest biodiversity of any type of land ecosystem how does biodiversity contribute to the sustainability of an ecosystem
Biodiversity contributes to the sustainability of an ecosystem in ways such as biodiversity, ecosystem stability, ecosystem resilience, nutrient cycling, pollination, and medicinal properties.
Biodiversity is crucial for the sustainability of an ecosystem as it plays a significant role in maintaining the functioning of ecosystems and providing a range of ecological services. In tropical rainforests, which have the highest biodiversity, the presence of numerous species of plants, animals, fungi, and microorganisms contributes to the sustainability of the ecosystem in the following ways:
Ecosystem Stability: Biodiversity helps to maintain the stability of an ecosystem by providing a balance between predator and prey populations, nutrient cycling, and decomposition.
Ecosystem Resilience: The greater the biodiversity of an ecosystem, the more resilient it is to disturbances such as climate change, natural disasters, and human activities.
Nutrient Cycling: Biodiversity helps in the efficient cycling of nutrients in the ecosystem. Different species of plants and microorganisms play a role in decomposing organic matter, recycling nutrients, and maintaining soil fertility.
In summary, biodiversity is essential for the sustainability of ecosystems. It provides ecological services that are critical for maintaining the functioning of the ecosystem and contributing to human well-being.

What is an exothermic reaction?When a chemical reaction takes place, energy is transferred to or from the surrounding in the universe. When the energy is transferred to the surrounding, there is a loss of energy, this reaction is called an exothermic reaction, and the temperature of the surrounding increases during this reaction.
The process of dissolving a substance is exothermic when more energy is released when water molecules bond to the solute particles in the solution than is used to break the solute particles apart. Because, more energy is released than is used in this process, the molecules which are present in the solution move faster, and thus results in an overall increase in temperature.
Therefore, the correct option is C.

What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

The different forms of the beef cattle color gene are called_
The different forms of the beef cattle color gene are called "alleles"
What are alleles?Alleles are alternative versions of a gene that arise from mutations and are located at the same position on a chromosome.
In the case of beef cattle, the color of the animal is determined by the interaction of multiple genes, including the color gene. The color gene can have different alleles that influence the color of the animal's coat. For example, one allele may result in a black coat color, while another allele may result in a red coat color.
The combination of alleles that an animal inherits from its parents determines its genotype, which in turn determines its phenotype or observed traits. Therefore, the different alleles of the beef cattle color gene can result in different coat colors, patterns, and markings in the cattle population.

B.water maintains temperature
C.what expands when it freezes
D.water dissolves many compounds
Answer:
Water has a neutral pH
Explanation:
None of the others exactly fit in with what this is saying, and water having a neutral pH allows the supplies and nutrients that it carries to stay safe within it throughout the way.
Sorry if this isn't correct or full-fledged explained like I normally do, I saw you said to hurry up and I didn't do my normal research and whatnot.
Anyways, hope this helped!
Sources: N/A
The characteristic of water that allows this process of carrying nutrients and gases is water has a neutral pH. Thus, the correct option for this question is A.
What are the characteristics of water?The characteristics of water are as follows:
It is a universal solvent. Due to the partial positive charge on hydrogen and partial negative charge on oxygen, it is a polar molecule. It has high heat capacity and high heat of vaporization. It has properties like cohesion and adhesion. Its solid form is less dense as compared to liquid.Due to having the property of neutral pH, water significantly performs movement across the entire body with the help of blood.
It does not form any barrier with the differences in the level of pH. So, along with blood, water carries nutrients and gases that must be required for proper survival throughout the body.
Therefore, water that has a neutral pH is the characteristic property that allows the carrying of nutrients and gases required for survival throughout the body.
