glycolosis that starts with glycogen instead of glucose can be considered to have a higher energy yield because
Glycolysis that starts with glycogen instead of glucose can be considered to have a higher energy yield because, phosphorylase produces a glucose phosphate without spending any ATP to do it.
How does glycogen affect glycolysis?Glycogen degradation in myocytes provides the energy needed for muscle contraction by introducing glucose-6-phosphate for glycolysis reaction. Phosphorylase kinase is an enzyme that activates glycogen phosphorylase, which releases glucose-1-phosphate from glycogen.Glucose phosphate is the initial intermediate of glucose metabolism and is essential for the liver's energy metabolism. It serves as a metabolic connector for glycolysis, the pentose phosphate route, glycogen synthesis, de novo lipogenesis, and the hexosamine pathway.The presence of glycogen as a glucose source in muscle cells allows ATP to be produced for a longer period of time during exercise. During glycolysis, the majority of other carbohydrates enter the cellular respiration pathway.Learn more about phosphorylase here: brainly.com/question/23078927

In E. coli bacteria, the lac operon contains genes that code for enzymes that break down lactose. Which statement describes when the genes in the lac operon are expressed?
The genes in the lac operon are expressed when lactose is present and the repressor protein is unable to bind to the operator region.
In E. coli bacteria, the lac operon contains genes that code for enzymes involved in lactose metabolism. The lac operon is a regulatory system that controls the expression of these genes. The expression of the genes in the lac operon is tightly regulated and depends on the presence or absence of lactose and glucose in the environment.When lactose is present, it binds to the repressor protein (lac repressor), causing a conformational change in the repressor. This change prevents the repressor from binding to the operator region of the operon. As a result, RNA polymerase can bind to the promoter region and transcribe the genes, leading to the production of the enzymes that break down lactose.In the absence of lactose, the repressor protein binds to the operator region and blocks RNA polymerase from initiating transcription. This prevents the expression of the genes in the lac operon.For more questions on protein

A student astronomer went outside and made two observations of the Moon that were several days apart. Her observations are shown in the diagram above. The light part of the Moon appeared to get smaller over time. Why did this happen?
Answer:
The light part of the Moon appeared to get smaller over time because of the change in the relative position of the Moon, the Sun, and the Earth. This is known as the lunar phase. The changing appearance of the Moon from the Earth's perspective is caused by the Moon's orbit around the Earth and the position of the Moon and Sun relative to the Earth. The Moon's phases are caused by the angle between the Moon, Earth, and Sun changing, as the Moon orbits the Earth. When the Moon is between the Earth and the Sun, the side facing the Earth is not illuminated by sunlight, so it appears dark, and this is called a new moon. When the Moon is on the opposite side of the Earth from the Sun, the entire side of the Moon facing the Earth is illuminated by sunlight, so it appears full, and this is called a full moon. As the Moon moves in its orbit, the angle between the Sun, Earth, and Moon changes, causing the illuminated portion of the Moon visible from the Earth to change, leading to different lunar phases.

Heart cells produce the protein cardiac myosin, which is critical in allowing for muscle contractions of the heart. Liver cells do not produce cardiac myosin.
Which statement explains this difference between heart cells and liver cells?
Heart and liver cells express different genes.
Heart cells rely on , R N A, , while liver cells rely on , D N A, .
Heart cells contain different genes from liver cells.
Liver cells destroyed the gene for myosin, but heart cells did not.
The most accurate statement that explains the difference between heart cells and liver cells in terms of their production of the protein cardiac myosin is "Heart and liver cells express different genes."
In multicellular organisms, different cell types have specific functions and characteristics that are determined by the genes they express. Genes are segments of DNA that contain the instructions for producing specific proteins. Each cell type expresses a unique set of genes that enable them to carry out their specialized functions.
In the case of heart cells and liver cells, they have different gene expression profiles. Heart cells specifically express the genes responsible for producing cardiac myosin, a protein essential for the contraction of the heart muscle. This allows the heart to effectively pump blood throughout the body.
On the other hand, liver cells do not express the genes for cardiac myosin production, as the liver has different functions unrelated to heart muscle contraction. The statement that heart cells contain different genes from liver cells is essentially expressing the same idea. Heart cells and liver cells have distinct gene expression patterns, leading to the production of different proteins and ultimately different cellular functions.
Both heart cells and liver cells utilize DNA as the genetic material that contains the genes responsible for protein production. RNA molecules are transcribed from DNA and play a crucial role in protein synthesis, but the distinction between heart and liver cells lies in the specific genes they express, not the reliance on different genetic materials.

What role have nitrates and phosphates played in damaging Muddy Creek?
Answer:
Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.
Explanation:
Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.
Nitrates and phosphate found in water are usually from plants that have been washed off by rain water and also from vehicles' exhaust.
When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).
This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a swamp and eventually a meadow
