All offspring will have red eyes because red is dominant and white eye color is a recessive trait.
What are dominant and recessive alleles?In genetics, when one allele is overriding the effect of another allele of the same gene, then it is called a dominant allele. While recessive alleles are those alleles that can not express themselves in the presence of a dominant allele.
Recessive traits can be expressed only when both alleles are recessive and homozygous, while dominant alleles can express themselves in both homozygous and heterozygous conditions.
In Drosophila melanogaster commonly known as the fruit fly, red eye color is dominant, and white eye color is recessive. So, Whenever a gene contains one red allele and one white allele, then red color dominates white eye color. Hence, all offspring will have red eyes.

tundra how it moves with carbon through the geosphere ?
Northern tundra and boreal ecosystems typically gain carbon (carbon sink) stored in plant biomass and new soil organic matter during the short summer growing season when plant photosynthesis and growth is greater than carbon respired by plants and soil back to the atmosphere.
How does carbon reach the geosphere?Carbon enters the geosphere through the biosphere when dead organic matter (such as peat or marine algae) becomes incorporated into fossil fuels like coal and organic-matter-rich oil and gas source rocks, and when shells of calcium carbonate become limestone through the process of sedimentation briefly described above.
What is carbon dioxide?Carbon dioxide is a chemical compound made up of two oxygen atoms and one carbon atom. The chemical representation is CO₂. Carbon dioxide was discovered by Scotsman Joseph Black in 1754. Structurally, carbon dioxide is made up of molecules of linear geometry and non-polar character.

A vibration fork that is tapped along sections of the spinal nerve system can be used to evaluate spinal nerve injury. Vibrations are detected by tactile receptors, a type of sensory receptor.
What is a spinal nerve?In order to modulate motor and sensory information from the body's periphery, spinal nerves, which are mixed nerves, directly communicate with the spinal cord. Each nerve is made up of fila radicular, or nerve fibers, that originate from the ventral and dorsal roots of the spinal cord. A spinal nerve is a mixed nerve that connects the spinal cord to the body and conveys motor, sensory, and autonomic signals. There are 31 pairs of spinal nerves in the human body, one on per side of the vertebral column. The combination of nerve fibers from the dorsal and ventral roots of the spinal cord creates each spinal nerve. Efferent motor axons are carried via the ventral roots.To learn more about spinal nerve, refer to:

© Gieagen is a protein, and insulin is a protein,
© Gynogen is a carbohydrate, and insulin Is a lipld,
O Ghoogen is a carbohydrate, and insulin is a protein.
Glycogen is a carbohydrate and insulin is a protein. So the correct option is D.
What are glycogen and insulin?
Glycogen is a stored form of glucose composed of several linked glucose molecules. Glucose (sugar) is the primary source of energy in your body. It is derived from carbs (a macronutrient) found in certain meals and fluids. When your body does not require glucose from the food you consume right away for energy, it stores it as glycogen in your muscles and liver for later use.
The process through which your body generates glycogen from glucose is known as glycogenesis. Glycogenolysis is the process through which your body breaks down glycogen for usage.
Your body converts the food you eat into glucose (sugar), which serves as your body's primary source of energy. Glucose enters the circulation, signaling the pancreas to produce insulin.
Insulin allows glucose in your blood to reach muscle, fat, and liver cells, where it can be used for energy or stored for later use. When glucose reaches your cells and levels in your circulation fall, your pancreas signals to stop generating insulin.
Therefore the correct option is D.

Target proteins are useful biomolecules that biologically active substances interact with and regulate. They are utilized during the transduction, transformation, and conjugation processes. An developing therapeutic approach known as targeted protein degradation (TPD) has the potential to address disease-causing proteins that have hitherto been very difficult to target with traditional small molecules. Proteases, kinases, G protein-coupled receptors (GPCRs), and nuclear hormone receptors are currently the protein targets for which effective medicines have been produced.Typically bioactive small compounds are coupled onto solid supports and then used to separate target proteins from the entire proteome for target protein identification.

On what basis are enzymes and proteins with allosteric properties different from those without allosteric properties?
Enzymes and proteins with allosteric properties different from those without allosteric properties are different based on their different dependence on substrate concentration.
Enzymes with an extra binding site for effector molecules outside of the active site are referred to as allosteric enzymes. Its catalytic capabilities change as a result of conformational changes brought on by the binding. Either an inhibitor or an activator may be the effector molecule.
When compared to other enzymes, allosteric enzymes stand out because of their distinctive features, which enable them to adapt to a variety of environmental situations. The unique characteristic of allosteric enzymes is the presence of an additional, substrate-binding allosteric site on top of their active site. Also, allosteric enzymes and protein enzymes can be distinguished on the basis of their dependency on the substrate as the allosteric enzymes can undergo conformational changes too and can bind to different substrates but those with protein structure will depend on one only.
