what is metabolism definition in biology?
Answers
Metabolism is a term used in biology to describe the chemical processes that occur within an organism to maintain life. It involves a complex series of chemical reactions that convert nutrients and other substances into energy and new molecules needed for growth and repair.
In simpler terms, metabolism is the process by which living organisms convert food into energy and the building blocks for growth and repair. This process involves several interconnected biochemical pathways, including the breakdown of molecules such as glucose and fatty acids, the synthesis of new molecules such as proteins and nucleic acids, and the generation of energy in the form of ATP (adenosine triphosphate).
Metabolism is essential for all living organisms, from the smallest bacteria to the largest mammals, and it plays a critical role in maintaining homeostasis, or the balance of biological systems. Disruptions in metabolism can lead to a wide range of health problems, including metabolic disorders such as diabetes, obesity, and heart disease

most blood from the brain flows down the internal jugular veins and then into
Answers
Most blood from the brain flows down the internal jugular veins and then into the heart.
This process is essential for the proper functioning of the body. What is the Internal Jugular Vein? The internal jugular vein is a vein in the neck that drains blood from the brain and face. It is one of the primary veins that connect the brain to the rest of the body. When blood is no longer required in the brain, it flows down the internal jugular vein into the heart. Blood flows in veins because of the pressure gradient between different parts of the body. Blood in the veins is under low pressure, so it relies on a system of one-way valves and muscle contractions to move it towards the heart. When the muscle contracts, it pushes blood towards the heart, while the valve prevents blood from flowing backward and keeps it moving forward. This ensures that the blood reaches the heart to be recirculated to the rest of the body. Importance of Blood Flow from Brain to Heart: The process of blood flow from the brain to the heart is crucial for the proper functioning of the body. Blood carries oxygen and nutrients to the brain cells and removes waste products from them. This process ensures that the brain receives an adequate supply of oxygen and nutrients, which is essential for its proper functioning. It also helps in maintaining the blood pressure in the brain, preventing the brain cells from getting damaged.

Which energy pathway is dominant when the body is at rest or during low-intensity, long-duration activity?Anaerobic glycolysisATP/CPOxidative energy pathwayLactate
Answers
The dominant energy pathway depends on the intensity and duration of the activity being performed. For low-intensity, long-duration activities, the oxidative energy pathway is dominant, while for high-intensity, short-duration activities, the anaerobic glycolysis pathway is dominant.
When the body is at rest or during low-intensity, long-duration activity, the oxidative energy pathway is dominant. This pathway utilizes oxygen to produce ATP (adenosine triphosphate), which is the energy currency of the body. This process involves the breakdown of glucose and fatty acids through a series of reactions that occur in the mitochondria of cells. The oxidative energy pathway is highly efficient, producing large amounts of ATP per glucose molecule compared to the anaerobic glycolysis pathway. Anaerobic glycolysis, on the other hand, is dominant during high-intensity, short-duration activities such as sprinting or weightlifting. This pathway does not require oxygen but instead uses glucose to produce ATP through a series of reactions that occur in the cytoplasm of cells. This process produces lactate as a byproduct, which can cause fatigue and muscle soreness.

based on the second law of thermodynamics, how much biomass of phytoplankton would be needed to produce 1kg
Answers
Approximately 100 kg of biomass of phytoplankton would be needed to produce 1 kg of organic matter, based on the second law of thermodynamics.
According to the second law of thermodynamics, when energy is converted from one form to another, some of it is lost as heat.
The maximum theoretical efficiency of any energy conversion process is determined by this law.
The second law of thermodynamics states that the amount of entropy (disorder or randomness) in a closed system will always increase over time.
This principle applies to all systems, including biological ones, as they all consume and convert energy to maintain their existence.Photosynthesis is the process by which phytoplankton convert sunlight and carbon dioxide into organic matter.
This organic matter is then consumed by other organisms in the food chain.
Biomass refers to the total mass of living organisms in a particular area.In order to determine how much biomass of phytoplankton would be required to produce 1 kg of organic matter, we must first understand the efficiency of photosynthesis.
Photosynthesis is known to have an efficiency of approximately 1%, which means that for every 100 units of sunlight absorbed, only 1 unit of organic matter is produced.
Therefore, to produce 1 kg of organic matter, approximately 100 kg of phytoplankton biomass would be required.

During the Anaphase of the m phase chromatids are separated and sorted so that each daughter cell eventually receives the same complement of chromosomes.
What happens during Anaphase?The real nuclear and cell division that occurs during mitosis, also known as the M phase, occurs when the duplicated chromosomes are equally divided between two progeny cells.Sister chromatids separate and centromeres split during anaphase. The shortening of the spindle fibers causes the sister chromatids to separate. This is similar to using a shorter fishing line to reel in a fish.

How does a lack of dissolvable oxygen in waterways affect aquatic biodiversity?
Answers
Answer:
I think ‘there will be less oxygen available for the aquatic life due to the microbial activity’. Too much microbial activity utilizes the oxygen dissolved in the water hence making the waters anoxic. This occurs especially after algae blooms. When the algae grow exponentially and later die, microbes that oxidize the organic matter for energy utilize the oxygen and cause dissolved oxygen in the water to deplete. This hence suffocates other aquatic life.
(This is what my sister sayed so I put it down)
Explanation:
answers: When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive.
explanation: The colder water is, the more oxygen it can hold. As the water becomes warmer, less oxygen can be dissolved in the water.

in bridges' experiments on drosophila, he found that rarely, among progeny from matings between white-eyed females and red-eyed males, he would observe unusual white-eyed daughters and red-eyed sons. he further found that these white-eyed females had an xxy genotype while the red-eyed males were xo. what did bridges conclude from these observations?
Answers
Bridges concluded that the gene responsible for eye color in drosophila is located on the X chromosome, and that the rare white-eyed daughters resulted from a non-disjunction event during meiosis in which the X chromosomes failed to separate properly.
This resulted in the daughters inheriting two X chromosomes and no Y chromosome, leading to an XXY genotype. The red-eyed sons resulted from a normal separation of the X and Y chromosomes during meiosis, leading to an XO genotype. These findings helped to establish the chromosomal theory of inheritance and the importance of sex chromosomes in determining genetic traits.
Bridges' experiments on Drosophila led him to important conclusions about sex determination and chromosomal inheritance. By observing the unusual white-eyed daughters (XXY) and red-eyed sons (XO) among the progeny of white-eyed females and red-eyed males, Bridges concluded that:
1. The eye color gene is located on the X chromosome. This explains why the white-eyed females (XXY) and red-eyed males (XO) exhibited different eye colors, as they inherited different X chromosomes with the respective eye color gene.
2. Sex determination in Drosophila is based on the presence of specific sex chromosomes (X and Y). In this case, the XXY genotype produced females, while the XO genotype produced males. This observation suggests that the number of X chromosomes is critical in determining an individual's sex.
These conclusions provided strong evidence for the chromosomal theory of inheritance and helped establish the role of sex chromosomes in determining an organism's traits and sex.
