what are some outcomes of nuclear fusion?
A.produce larger materials from the collision of smaller materials
B.Release energy
C.produce smaller materials from the collision of larger materials
Answer:
A. produce larger materials from the collision of smaller materials
Explanation:
The outcome of nuclear fusion reaction is that it produces larger materials from the collision of smaller materials.
Nuclear fusion is the combination of small atomic nuclei into larger ones with the release of a large amount of energy. The energy released provides the needed temperature for another set of atoms to fuse. This process in turn yields a bulkier material accompanied with the release of a lot of energy.The method animals use to attract mates to reproduce

How can humans influence traits in dogs or other organisms?
Answer:
In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.
Dog breeding is another prime example of artificial selection. Although all dogs are descendants of the wolf, the use of artificial selection has allowed humans to drastically alter the appearance of dogs.
Explanation:
Humans can influence traits in dogs or other organisms by the process of artificial selection through which desired characters can be added to the offspring.
How can humans influence traits in other organisms?Humans can influence the process of natural selection by the process of artificial selection, or selective breeding. In artificial selection, humans can select a specific set of desirable traits in the agricultural plants or animals, and thus produce desirable offspring (products) for benefit.

The function of the cork cambium is to produce
Answer:
The cork cambium produces cork and phelloderm.
Explanation:
Cells' structural components decide their function. Cells arrange themselves into tissues, where specialized cell types carry out their functions in tandem. As cells mature, their function may even change over time, as they undergo certain subcellular changes in protein expression and signaling.
In larger plants, rigid tissues are needed to help support their modified stems, and transport water, minerals, other nutrients and food to different regions. Cork cambium is an unspecialized tissue found in the outermost plant layers. These act as meristematic regions; here, new tissues arise, growing outwards- these include:
phelloderm- they mature into inner secondary cortex cork- dead air-filled cells called cork that form a strong protective layer on the stems of woody vascular plants.Describe the different body senses and how they function.
Those senses are sight, smell, hearing, taste, and touch. We see with our eyes, we smell with our noses, we listen with our ears, we taste with our tongue, and we touch with our skin.

Which statement best describes the human respiratory system?
The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs, and blood vessels. The muscles that power your lungs are also part of the respiratory system. These parts work together to move oxygen throughout the body and clean out waste gases like carbon dioxide.
Answer: It is composed of a network of moist passageways that permit air to flow from the external environment to the lungs.

Answer:
Gamete cell
Explanation:
Because I just got the question wrong and it showed me the right answer.
A gene alteration that takes place in a parent's reproductive cells (egg or sperm) and has an impact on the child's genetic makeup is known as a “germ line mutation.”
What is mutation?A more or less permanent change to the genetic code (the genome) of a cell in a living thing or of a virus that can be passed on to the offspring of the original cell or virus. Unlike viral genomes, which can be either DNA or RNA, all creature genomes are made of DNA.
Somatic mutation: A variation in a gene that takes place in the developing embryo that may evolve into a child after conception. All cells in the developing organism have these, except for the sperm and egg.
Therefore, a “germ line mutation” is a gene change that occurs in a parent's reproductive cells (egg or sperm) and affects the child's genetic composition.

During cellular respiration, the electron transport chain is coupled to the generation of an electrochemical gradient across the mitochondrial inner membrane.
The statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.In cellular respiration, an electrochemical gradient is created by pumping ions (e.g. H+) against a concentration gradient from the mitochondrial matrix into the intermembrane space.Subsequently, this gradient is used by a protein complex known as ATP synthase to generate ATP (the energy coin of the cell) from ADP and monophosphate.In conclusion, the statement 'the movement of motor proteins is powered by the formation of ADP and inorganic phosphate from ATP' describes an energy-releasing process that is coupled to the energy-requiring process in the cell.

definition of hypotonic solution isotonic solution and hypertonic solution
Answer: hypotonic solution- a lower concentration of solutes than another solution
isotonic solution- a solution that contain equal concentrations of impermeable solutes on either side of the membrane and so the cell neither swells nor shrinks.
hypertonic solution- A solution that contains more dissolved particles (such as salt and other electrolytes) than is found in normal cells and blood.
Explanation: searched it up for you
Answer:
Hypotonic solution: lower concentration of solutes compared to a medium or reference solution.
Isotonic solution: same concentration of solutes compared to another solution.
Hypertonic solution: higher concentration of solutes compared to another one.
Explanation:
A solution is a mixture where a solute is diluted in a solvent that is usually homogeneous, and the solute and solvent do not interact through chemical reactions.
In biology, we speak of hypertonic, isotonic and hypotonic solutions when comparing intracellular and extracellular media at a given time. Taking as reference the cellular cytoplasm:
Hypotonic: lower concentration of solutes in the extracellular space Isotonic: the same concentration of solutes, with respect to the cytoplasm Hypertonic: higher concentration of solute in the extracellular space.The difference in concentrations given by the hypotonic and hypertonic solutions define the dynamics of the movement of solutes or water through the cell membrane, forming gradients, where a solute passes from the place of highest concentration to the place of lowest concentration, or the water passes from the medium with the lowest concentration of solutes to the one with the highest concentration.

Explanation:
How might an individual lose their sight or their hearing but not have direct damage to their eyes or ears
An individual can lose their sight and hearing ability without any direct damage to their eyes or ears due to the condition known as Usher syndrome, which is a genetic disease.
• Usher syndrome is the most common syndrome that influences both vision and hearing.
• The prime signs of the syndrome are hearing loss or deafness and an eye disease called RP or retinitis pigmentosa.
• In Usher syndrome, hearing loss can take place due to the unusual growth of hair cells within the inner ear.
• The RP at the beginning results in night blindness and a loss of side vision due to the progressive degeneration of retina cells.
• With the advancement in RP, the field of vision becomes more narrow till the central vision remains, the condition is termed tunnel vision.
Thus, it is the Usher syndrome, which can lead to loss of sight or hearing, however, does not cause direct damage to the ears and eyes.
