Which characteristic explains why algae blooms are more likely to grow out of control in lentic ecosystems instead of lotic ecosystems?
O Photosynthetic organisms can grow undisturbed in sunlit, nutrient-rich lentic ecosystems.
O More photosynthetic organisms are found in lentic ecosystems than in lotic ecosystems.
O Lotic ecosystems have lower nutrient and dissolved oxygen levels than lentic ecosystems.
O Lentic ecosystems have higher turbidity, which is preferred by photosynthetic organisms.
Answers
Given the characteristics of lentic ecosystems, we can conclude that algae blooms are more likely to grow out of control because photosynthetic organisms can grow undisturbed in sunlit, nutrient-rich lentic ecosystems.
Lentic ecosystems are those whose water is still. This kind of ecosystem includes bodies of water such as:
LakesPondsReservoirs SeepsPoolsand so on. These can be temporary or permanent and are found in a wide range of sizes.
Lentic ecosystems minimize the mixing of the water, allowing the water to absorb more sunlight and become warmer. Warmer water allows organisms such as algae to move easier, allowing them to float to the surface quicker and absorb more sunlight. This creates a chain reaction given that the sunlight absorbed by the algae heat the water even more, thus promoting more algae growth. For these reasons option one is correct.

HELP!!! A student observes that she's always sleepy shortly after eating lunch, and she wants to be able to pay better attention in her mid-afternoon class. She tried doing 10 jumping jacks just before the class, but still felt sleepy around the middle of the class. The next day, she tried sipping water throughout the class and found that she could pay attention until the end of the class. The student now brings a water bottle to class.
*Identify how this student applied the scientific method to solve her problem.*
Answers
Answer:
In this scenario, the student applied the scientific method to solve her problem in that she first established there was a problem, then formulated some hypotheses about why there was a problem, and then did experiments to test the hypotheses.
Explanation:
Hope This Helps!
It's essential for students (and everyone) to stay adequately hydrated throughout the day to maintain overall well-being and cognitive function. Bringing a water bottle to class is a practical and healthy habit that can help the student remain focused and attentive during the class and other daily activities.
Hydration and Cognitive Function: Proper hydration is essential for optimal cognitive function. When the body is dehydrated, it can lead to feelings of fatigue and decreased mental alertness. Drinking water helps maintain the balance of body fluids, and the brain relies on adequate hydration to function at its best.
Blood Flow and Oxygenation: Staying hydrated supports proper blood circulation, including to the brain. Sipping water can help ensure that oxygen and nutrients are efficiently delivered to brain cells, enhancing cognitive performance.
Thirst as a Sign of Dehydration: Feeling sleepy or fatigued after eating lunch could be a sign of dehydration, especially if the lunch is salty or doesn't contain enough fluids. By sipping water during the mid-afternoon class, the student is addressing any potential dehydration and its associated effects on attention and alertness.

how is the energy that earth absorbs different from the energy that earth emits
Answers
Answer: thats geology not biology
Explanation:
Energy that earth absorbs different from the energy that earth emits is called geology.
What is Geology?The word geology means 'Study of the Earth'.
It is also known as geoscience or earth science, Geology is the primary Earth science and looks at how the earth formed, its structure and composition, and the types of processes acting on it.
Geology is concerned with the history of the earth over the course of its 4.5 billion year life. By studying the structures of the earth we can unlock its hidden past and anticipate its future.
All levels of schooling include geology. The study of geology fosters analytical abilities, a global perspective on the globe and its interconnected systems, and a grasp of numbers and maps.
Therefore, Energy that earth absorbs different from the energy that earth emits is called geology.

Answer:
Explanation:
1. The Moon continues to spin away from the Earth, at the rate of 3.78cm (1.48in) per year, at about the same speed at which our fingernails grow. ... The migration of the Moon away from the Earth is mainly due to the action of the Earth's tides
2. Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. ... In addition, the exhaust from cars, trucks, and buses releases nitrogen oxides and sulfur dioxide into the air. These pollutants cause acid rain.
3. Formation. When the solar system settled into its current layout about 4.5 billion years ago, Earth formed when gravity pulled swirling gas and dust in to become the third planet from the Sun. Like its fellow terrestrial planets, Earth has a central core, a rocky mantle, and a solid crust.

9. Cause the core of the earth is trillions of degrees.
10. There would be mass flooding from sea levels rising, severe weather changes, deadly chemical releases, and mass greenhouse gasses that would leak into the atmosphere. Scientists say we need to stop the planet from rising in temperature by just 1° Celsius, or this could happen sooner than we think.
11. Differences in temperature, pressure, and structural formations in the mantle and crust cause magma to form in different ways. ... The rock then cools into new crust. Decompression melting also occurs at mantle plumes, columns of hot rock that rise from Earth's high-pressure core to its lower-pressure crust.

Q6.7. If a person is heterozygous for the triangle32 allele of the CCR5 gene, how many of the four daughter cells produced by have the3
Answers
Given the characteristics of hereditary genetics, if a person is heterozygous for a given allele, of the four daughter cells produced, the amount that would have the gene is dependent on the spouse's genetic makeup but ranges from 50-100%.
When we say that an individual is heterozygous for a given trait, we mean that of the two alleles that this individual possesses for the given trait, one is of the desired type and one is not. Whereas an individual who is hom-ozygous for a given trait will have both alleles of the same kind.
For example, if we were to look at the allele for blue-colored eyes, a heterozygous individual will have one allele which corresponds to blue coloration, and one allele that corresponds to another color, and a hom-ozoygous will have both alleles for blue eyes. In order to accurately predict the expression of the gene in the offspring of an individual, we use a punnet square (see attached image).
Assuming that the allele in question is dominant in nature, this allows us to see that of the four daughter cells of an individual that is heterozygous for the given allele, the number that will have the triangle32 allele are:
50% (2) if crossed with a spouse who does not have the allele75% (3) if crossed with a spouse who is also heterozygous for the allele100% (4) if crossed with a spouse who is hom-ozygous for the alleleIn conclusion, we can say that the outcome of the cross is entirely dependent on the genetic makeup of the spouse, as well as the dominant or recessive nature of the allele in question, but can accurately predict an outcome in the range of 50-100%.

What was Mendel's most significant conclusion from his research with pea plants?

Mendel's most significant conclusion from his research with pea plants is that Traits are inherited in discrete units and are not the results of blending.ʺ The correct option is B)
What was Mendel's law?Mendel Gregor was s scientist and a botanist. He gave three laws of inheritance. The three laws are of very importance to the field of genetics.
The law of inheritance and the law of segregation say that the traits in the other generation are always passed down segregated, not blended. The traits are just dominant and recessive in the generations.
