When a child is born with a faulty gene that causes a serious disease, it means that they have inherited a mutated gene from one or both parents. The mutated gene contains incorrect or incomplete instructions for making a protein, which can cause a variety of problems in the body. The severity of the disease depends on the specific gene that is affected and the degree to which it is mutated.
Some faulty genes can cause diseases that are present from birth, while others may not cause symptoms until later in life. In some cases, a person may inherit a faulty gene but not develop the disease themselves, while still being a carrier of the gene and able to pass it on to their children.
Answer: a child born with faulty gene that causes a serious disease is result of "gene change or a mutation"
Explanation:
Gene change cane sometimes cause health conditions such as cystic fibrosis and sickle cell disease. A gene change also can cause birth defects, like heart defects. A gene can change on its own or it can be passed from parents to children.

Any given area of the retina relays its information to a corresponding location in the visual cortex at the back of your brain.
The retina is a very thin layer at the back of the eyeball that can capture light which is then processed so that humans can see objects clearly. In the retina there are rod cells which receive colorless rod light and cone cells which are capable of receiving strong and colored light rays.
The visual cortex, located in the occipital lobe, is the first to process image impulses received from the retina. There are two visual cortices, namely the primary visual cortex and the extraestriated cortex. The information we receive from the eyes to the visual cortex is passed on until it finally reaches the cerebral cortex to be processed so that we can recognize colors, shapes, and movements.

Construct a scientific explanation about how glucose is used in a tree to help it grow. Focus on answering the question: How do the internal structures of the tree function together to help a tree take in and lock up carbon atoms from carbon dioxide in the wood of the tree as it grows? Make sure to cite the relevant evidence from this lesson (and others as needed) and the way this connects to how the structures inside the tree work together to help the tree lock up carbon atoms (originally taken in as CO2 from the air) within the wood of the tree
The internal structures of a tree work together to take in carbon dioxide (CO2) from the air and convert it into glucose through the process of photosynthesis.
During photosynthesis, the chloroplasts in the mesophyll cells of the leaves use energy from sunlight to convert CO2 and water into glucose, releasing oxygen as a byproduct.
The glucose produced during photosynthesis is used by the tree as a source of energy and as a building block for the formation of cellulose, hemicellulose, and lignin, the main components of the cell walls in the tree's trunk, branches, and leaves.
The glucose is transported from the mesophyll cells of the leaves to the other parts of the tree through the phloem, a tissue that functions as a network of tubes for the transport of sugars and other nutrients from the leaves to the rest of the tree.
The cellulose, hemicellulose, and lignin produced by the tree help to reinforce the cell walls, giving the tree its structural integrity. As the tree continues to grow, more glucose is produced and used to build the cell walls, and the tree is able to lock up more and more carbon atoms within its wood.

What are the functions of tube feet in a starfish?
Answer:
Tube feet in echinoderms have a few functions. The obvious one is locomotion. The feet are powered by the water vascular system. They are also important for absorbing oxygen (remember that the body of sea stars and their relatives are covered in bony plates called ossicles), for eliminating nitrogenous waste products of metabolism, and grasping prey. Sea stars are capable of pulling a bivalve apart by exerting pull on the two shells and essentially tiring the prey out as the muscles the prey eventually tire. Once there is an opening, the sea star everts its stomach into the prey.
If you've ever picked up a sea star and turned it over, you probably noticed the hundreds of tube "feet" lining its arms. It is these suction-bottomed tubes that the sea star uses to move about. It draws in water and channels it to canals that run throughout its body, usually ending in the tube feet.
Tube feet function in locomotion, feeding, and respiration. The tube feet in a starfish are arranged in grooves along the arms. They operate through hydraulic pressure. They are used to pass food to the oral mouth at the center, and can attach to surfaces.

The curve represents an enzyme's reaction velocity without any inhibitor present is the curve where the reaction rate reaches its maximum level,
The curve represents the velocity in the presence of a noncompetitive inhibitor is the curve where the reaction rate does not reach its maximum rate
the curve represents the velocity in the presence of a competitive inhibitor isthe curve where the reaction rate is inhibited at the start and manages to reach its maximum level.
Enzymes are biomolecules that function as catalysts, namely compounds that accelerate the process of a chemical reaction. Cells produce enzymes which are generally in the form of proteins as catalysts to help metabolism in cells which are concentrated in certain organelles where reactions take place. Enzymes will accelerate the rate of chemical reactions, namely changes in the concentration of reactants or products in a unit time. Without an inhibitor, the chemical reaction rate curve will run quickly to reach its maximum to form a new product as a result of the reaction.
Inhibitor is a chemical substance that can inhibit or slow down a chemical reaction. In non-competitive inhibitors the reaction inhibiting molecule will attach to the active site of the enzyme so that the substrate cannot attach. Therefore the reaction rate will decrease so that the curve will show the reaction will run slowly because it does not reach its maximum. Noncompetitive inhibitors slow down the overall rate of a chemical reaction.
While competitive inhibitor molecules will compete with the substrate for attachment to the active site of the enzyme. So the enzyme cannot produce the enzyme substrate complex. The curve will show that competitive inhibitors only inhibit at the beginning of a chemical reaction, in the end the reaction rate will reach its maximum level with the addition of many substrates.

Based on this information, water would move across the selectively permeable membrane from solution a (containing 50 percent glucose) to solution b (containing 25 percent glucose). There would be a net movement of water from solution A to solution B.
This is because of the osmosis principle, which states that water moves from a high-concentration area to a low-concentration area to balance the concentration of solutes on each side of the membrane.
Water would move from solution a to solution b to dilute the glucose in solution b and balance the concentration of solutes on both sides of the membrane because solution b has a lower glucose concentration than solution a.

Describe the change in the percentage of light colored moths and dark colored moths between 1850 and 1900. Please describe the change in the percentage between 1950 and 2000 as well.
Answer:
Explanation:
The change in the percentage of light colored moths and dark colored moths between 1850 and 1900 is a result of industrial melanism, a phenomenon in which the frequency of dark-colored individuals increases in a population over time in response to increased levels of pollution and soot. During this period, the population of light colored moths, which were once abundant, began to decline as the dark colored moths, which were previously rare, began to increase in number. This change was due to the increased visibility of the dark colored moths, which were better able to blend in with the dark soot-covered trees and avoid being preyed upon by birds.
Between 1950 and 2000, the trend of industrial melanism continued, but at a slower rate. The dark colored moths remained more numerous than the light colored moths, but the difference between the two populations became less pronounced as environmental regulations reduced the levels of pollution and soot in the environment. The decrease in industrial melanism is a testament to the effectiveness of environmental regulations in protecting biodiversity and restoring the balance of ecosystems.
In conclusion, the change in the percentage of light colored moths and dark colored moths between 1850 and 1900 was a result of industrial melanism, while the change between 1950 and 2000 was a result of both industrial melanism and the success of environmental regulations.
