during respiration, does glucose become more oxidized or more reduced?
Answer:
During cellular respiration, glucose becomes more oxidized as it is broken down and releases energy.
Explanation:
During cellular respiration, glucose undergoes a process of oxidation. In other words, it becomes more oxidized as it is broken down into smaller molecules and releases energy.
Oxidation is a chemical reaction in which a molecule loses electrons, making it more positively charged. During cellular respiration, electrons are stripped from glucose and transferred to oxygen, which combines with hydrogen ions to form water. This transfer of electrons results in the conversion of glucose into smaller, more highly oxidized molecules, such as carbon dioxide and water.
T/F? Right renal artery longer than the left renal artery
The given statement "Right renal artery longer than the left renal artery" is true because in order to reach the right kidney, it needs to pass behind the inferior vena cava.
The renal arteries are basically the part of our circulatory system. They happen to carry large amounts of blood from the aorta (which is the heart’s main artery) all the way to the kidneys. Approximately half a cup of blood passes through the kidneys from these renal arteries every minute.
We have two renal arteries, one for each of our kidneys. The right renal artery basically connects to the right kidney whereas the left renal artery connects to our left kidney.

Rough endoplasmic reticulum is the system of membrane saccules that is studded with ribosomes and capable of producing proteins.
What do you mean by membrane?
A membrane is a thin, semi-permeable barrier that separates two environments, such as cells or organelles inside a cell, or the body and its environment. It is typically composed of lipids, proteins, and carbohydrates that are arranged in a phospholipid bilayer. Membranes allow certain substances to pass through while blocking others, thus regulating the movement of materials and energy.
Rough endoplasmic reticulum (ER) is a network of interconnected membranes within the cell that extends throughout the cytoplasm. It has a rough appearance due to the presence of ribosomes attached to the outer surface of the membrane. These ribosomes are responsible for the production of proteins. The ER is the site of protein synthesis as the ribosomes attached to the outer membrane of the ER synthesize proteins according to the instructions of the messenger RNA (mRNA). The proteins that are produced in this process are then transported to other compartments of the cell, such as the Golgi apparatus, for further processing. In addition, the ER also plays a role in the transport of lipids, carbohydrates and other molecules throughout the cell.

The microspore divides by mitosis producing two cells. The first of the cells (the generative cell) is small and is formed inside the second larger cell (the tube cell). The members of each part of the microspores separate from each other. A double-layered wall then develops around each microspore.
These steps occur in sequence and when complete, the microspores have become pollen grains. Microspore embryogenesis is said used in biotechnology to produce double haploid plants, which are immediately fixed as homozygous for each locus in only one generation. The haploid microspore is then stressed to trigger the embryogenesis pathway and the resulting haploid embryo then doubles its genome spontaneously.

Of the options given, red light (which has a wavelength range of 620 nm to 750 nm) would be the best choice to avoid in the experiment. This is because red light is absorbed strongly by chlorophyll a and b, which are the primary pigments involved in photosynthesis, and it may interfere with the measurement of activity at other wavelengths.
