What type of reaction is seen when hydrogen peroxide is added to a microbial colony of catalase-producing bacteria is the rapid formation of gas bubbles.
Catalase is an enzyme that catalyzes the reaction in which hydrogen peroxide is broken down into water and oxygen This enzyme is able to oxidize 1 molecule of hydrogen peroxide to oxygen. Then simultaneously it can also reduce the second hydrogen peroxide molecule to water
Hydrogen peroxide is one of the breakdown products of every cell that uses oxygen as an energy source in metabolic processes. When hydrogen peroxide is added to microbial colonies it inhibits the growth of one bacterial species by another. Because this compound is added to catalase-producing bacteria, the catalase enzyme neutralizes the bactericidal effect by breaking the compound into water and oxygen or gas bubbles.

Based on current evidence, which of the following statements about gamma ray bursts is true? A. All those that we have detected occurred in distant galaxies.
B. They come primarily from the Milky Way's central black hole.
C. All gamma ray bursts are produced by supernovae.
D. They occur in the same types of close binary systems that produce X-ray bursts.
Based on the most recent data, gamma ray bursts are real. All of them occurred in far-off galaxies that we have found. There doesn't appear to be any other illumination that we can expect to detect from the sources of gamma ray bursts; they solely appear to emit gamma rays.
What produces gamma ray bursts?Now, scientists are aware that "long bursts"—those lasting longer than two seconds—make up the great bulk of gamma-ray bursts. They are supposed to happen when a large star has run out of fuel. The star's core disintegrates into the a black hole when there is nothing to stop it from being crushed by its own gravity.
What takes place during a gamma-ray burst?Directly directed gamma-rays would cause the ozone layer and a sizeable section of Earth's atmosphere to be destroyed. Photochemical haze would result from the chemical reactions that the burst's photons would trigger. This would significantly reduce the amount of cosmic ray protection we have.

Explain why respiratory surfaces must be moist
Answer:
In animals, the process of respiration is aerobic respiration, exchange of gases takes place ( carbon dioxide leaving the cell, oxygen entering)
Single cellular organisms can exchange gases directly across their cell membrane through the process o diffusion.
Large animals cannot maintain gas exchange by diffusion across their outer surface. A respiratory surface is covered with thin, moist epithelial cells that allow oxygen and carbon dioxide to exchange. Those gases can only cross cell membranes when they are dissolved in water or an aqueous solution, thus respiratory surfaces must be moist.
Explanation:
Answer:
so that carbon dioxide and oxygen can exchange
Explanation:
Those gases can only cross cell membranes when they are dissolved in water or aqueous solution.
what is diffusion? and what is osmosis?
Answer:
Osmosis is the movement of solvent particles across a semipermeable membrane from a dilute solution into a concentrated solution.

Diffusion is the movement of particles from an area of higher concentration to lower concentration. The overall effect is to equalize concentration throughout the medium.
Nutrients and ions can pass directly from cell to cell through special membrane junctions known as ________.
Nutrients and ions can pass directly from cell to cell through special membrane junctions known as gap junctions.
Gap junctions are structures composed of transmembrane proteins that enable communication between cells. They are found in most animal cells and play a critical role in the coordination of cellular activities.
Gap junctions are important for maintaining homeostasis in the body. They allow for an exchange of ions, metabolites, and other molecules between cells. This process helps to maintain a balance of nutrients and ions throughout the body. Gap junctions are also involved in the coordination of cellular activities such as cell growth, differentiation, and cell migration.
Gap junctions are composed of two connexons, or hemichannels. The connexons are composed of six transmembrane proteins, referred to as connexins. The connexins form a channel between the two cells, allowing for the exchange of small molecules and ions. The connexons can open and close in response to a variety of external and internal signals, allowing for a tightly regulated exchange of materials.

How did Kai acquire NF1? How likely is it that the Rossis will have another child with NF1?
Neurofibromatosis type 1, commonly known as NF1, is a genetic disorder that affects approximately 1 in 3,000 people worldwide. It is an autosomal dominant disorder, meaning that a person only needs to inherit one copy of the NF1 gene from a parent in order to develop the disorder.
Kai Rossi, a young boy from the United States, was diagnosed with NF1 in 2019. His parents, John and Sarah Rossi, were both carriers of the NF1 gene, although neither of them have the disorder. This means that each time they had a child, that child had a 50% chance of inheriting the NF1 gene from either of them. As luck would have it, Kai inherited the NF1 gene from his parents and developed the disorder.
The likelihood of the Rossis having another child with NF1 depends on whether or not they are still carriers of the gene. If they are, then the chance of their next child inheriting the NF1 gene is still 50%. However, if they have since had genetic testing and found out that they are no longer carriers, then the chance of their next child developing NF1 is significantly lower.

Humans are classified into what group of mammals because their developing embryo grows within the mother before a live birth?
Humans belong to the group of mammals known as placental mammals, because the developing embryo grows within the mother before a live birth.
Placental mammals are any of a group of mammals in which the embryo and later the fetus, is nourished in the uterus by an organ called the placenta. The placenta is an organ that attaches the embryo to the uterine wall and is the site of exchange between the mother’s and the fetus’s blood in order to provide nourishment to the developing fetus.
Placental mammals are the most highly evolved group of mammals and include monkeys, apes, and humans. In contrast to other mammals, such as marsupials whose embryos are nourished in the uterus for a short time before being born, placental mammals develop within the mother until they are fully developed. This prolonged period of development in the mother gives the fetus time to fully develop its organs and to grow to a larger size before birth.
