How did the evolution of photosynthetic organisms lead to changes in the hydrosphere?
Answer:
This cycle of water moving through the atmosphere and the energy changes that accompany it, is what drives weather patterns on earth. ... This water is needed in photosynthesis, the food production process in plants. Transpiration (evaporation of water from the leaf surface) then returns water back to the atmosphereExplanation:
All the water on the surface of the world, including seas and lakes, as well as water above the surface of the globe, including clouds, are collectively referred to as the hydrosphere.
What role of photosynthetic organisms in hydrosphere?During photosynthesis, plants use carbon dioxide from the environment to create the nutritional components of food. In lakes and the ocean, carbon is dissolved in the hydrosphere.
Weather patterns on Earth are governed by the cycle of water passing through the atmosphere and the corresponding changes in energy.
For plants to produce food through photosynthesis, they need this water. Water is then returned to the atmosphere by transpiration, the evaporation of water from the leaf surface.
Therefore, evolution of photosynthetic organisms lead to changes in the hydrosphere.

list one example of a falsifiable scientific hypothesis about oreo cookies.
Answer:
Oreo cookies are healthy for us
Explanation:
Look at the nutrition label
Example of Falsifiable Scientific Hypothesis about Oreo Cookies:
"The presence of a specific ingredient in Oreo cookies contributes to increased shelf life."
The example hypothesis presented is falsifiable because it proposes a specific claim that can be tested and potentially proven false through experimentation and observation. In this case, the hypothesis suggests that the presence of a particular ingredient is linked to an increased shelf life of Oreo cookies.
To test this hypothesis, a series of experiments can be designed. One approach might involve preparing batches of Oreo cookies with and without the specific ingredient, then storing them under controlled conditions that simulate real-world storage conditions. The cookies' freshness, texture, and other relevant factors could be monitored over time. If the cookies with the ingredient do not consistently show a prolonged shelf life compared to those without the ingredient, the hypothesis could be rejected.
Falsifiability is a key criterion of a scientific hypothesis because it ensures that the hypothesis can be empirically tested and either confirmed or disproven. In this case, the hypothesis about the ingredient's impact on shelf life can be subjected to experimental investigation, allowing for objective assessment and potential modification of our understanding based on the outcomes. Science relies on falsifiable hypotheses to advance knowledge through evidence-based testing and analysis.

What characteristics of an organism can affect gene function?
The genetic makeup of an organism at fertilization determines only the
Genes are encoded with different traits. Each of these traits carry different functions to the new offspring that is developing. ... The genes that an organism inherits can affect gene function. For example they can have a recessive gene for something thatmight affect them. I hope that this helps you out, have a fantastic day!!If an organism has an ‘n’ of 32, how many chromosomes are in its somatic cells? How many chromosomes are in its gametes?
[tex]n[/tex] represents the haploid number of an organism. We know that gametes are haploid, therefore there will 32 chromosomes in each gamete. A somatic cell on the other hand is what we know as a body cell, which is a product of mitosis. Mitosis produces diploid cells which is represented by [tex]2n[/tex]. In order to find this value, simply multiply the [tex]n[/tex] value by 2 and you should get 64 chromosomes in each somatic cell.
If a cell that has 8 chromosomes goes through mitosis, how many chromosomes will each new cell have?.
Answer:
8 chromosomes
Explanation:
The daughter cells will have the exact same amount of chromosomes as the parent cells. Cells that go through mitosis make two exact copies of each other, so they would have the same amount of cells. (I hope this helps and I'm so sorry if it's wrong)
How does water shape the Earth? Choose all that apply?
Answer:
The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.
Explanation:
A brown-eyed man with a blue-eyed mother marries a brown-eyed woman with a blue-eyed father. What is the probability that their first child will be brown-eyed
This is based on my assumption that brown is dominant over blue.
Since both parent have parents who are homo_zygous recessive, this tells us that both parents will be hetero_zygous.
When you cross two hetero_zygous parents, it can produce these genotypic and phenotypic ratios:
Genotypic
BB : Bb : bb
1 : 2 : 1
Phenotypic
brown : blue
3 : 1
Therefore there is a 75% chance that they will produce a brown-eyed offspring.
Which lipoprotein carries cholesterol to the cells in your body, but can get stuck in arteries while traveling in the blood, depositing cholesterol that eventually leads to plaque formation?.
LDL (low-density lipoprotein) carry cholesterol from the liver to the tissues and can contribute to the formation of plaque that builds up in the arteries.
What are lipids?Lipids are soluble in fat and to circulate in the blood, which is an aqueous medium, they form lipoprotein complexes called lipoproteins, these constitute a transport medium and circulating reservoir for lipids.
Characteristics of LDL (low-density lipoprotein)Low-density lipoproteins, composed of 50% triglycerides, are the ones that transport the lipids synthesized in the liver to other parts of the body.LDL, composed mainly of cholesterol, when in excess, also deposits it on the walls of the arteries, contributing to the formation of plaque.Therefore, we can conclude that excess LDL (low-density lipoprotein) poses a health risk because it facilitates the accumulation of fat in the arteries.

What could happen if negative feedback inhibition did not signal the pancreas to stop producing insulin when blood sugar levels drop to normal levels?
Answer:
the pancreas releases the hormone glucagon. This moves/goes to the liver in the blood and causes the break-down of glycogen into glucose. The glucose goes into the blood stream and glucose levels increase back to normal.
Explanation:
the pancreas releases the (chemical produced by the body) glucagon. This moves/goes to the liver in the blood and causes the break-down of glycogen into glucose. The glucose goes into the blood stream and blood sugar levels increase back to normal(usual/ commonly and regular/ healthy).

What is the importance of the perichondrium that surrounds cartilage?.
Answer:
The perichondrium located around the cartilage has many important and vital functions. The cartilage is a dynamic structure which remains in constant rigorous motion and highly prone to wear and tear. The perichondrium contains an outer layer of fibrous elastin which resists excessive outwards expansion of the cartilage. Also, a large number of nascent and dividing cartilagenous cells are located in the inner part of the perichondrium which help in growth, repair and wear and tear along with repair and maintenance of the cartilages.
