Which correctly describes crossing over?
the process whereby non-sister chromatids exchange genetic material
the process whereby homologous chromosomes are pulled to opposite poles of the cell
the process whereby sister chromatids are pulled to opposite poles of the cell
the process whereby homologous chromosome pairs align randomly along the metaphase plate
The correct option is A ie the process whereby non-sister chromatids exchange genetic material
Between prophase I and metaphase I, a process known as crossing over occurs in which two homologous non-sister chromatids join up and exchange various pieces of genetic material to create two recombinant chromosome sister chromatids.When genetic material is switched between two chromosomes, this process is known as crossing over.It is in charge of causing genetic variation among members of a species.Only the reproductive cells known as gametes undergo this process.The steps involved in crossing over are as follows:1) Synapsis.
2) Chromosome duplication
3) Crossing over.
4) Terminalizataion.

what is potential energy
Answer:
The energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system.
Explanation:
Energy is a delicate notion that is extremely difficult to master. Energy is sometimes described as the ability to accomplish labor, that is, to push anything against a force. That isn't completely correct, since due to the Second Law of Thermodynamics and the fact that much energy is merely mass, there is a lot of energy that isn't accessible to do any work. We're on somewhat better ground with potential energy. When we say there is potential energy, we mean that there is something in a system that, if permitted to alter, has the capacity to accomplish work. Saying that there is potential energy is a form of abbreviation. Consider gravitational potential energy. If two masses are separated by a distance, we might let them fall together and accomplish some work, perhaps by pulling a rope tied to a wheel or whatever. We have the energy to get there. Of course, it is a fraction of the overall energy in the system. When we get to notions like that, we must count a lot more. Nonetheless, some cosmological models require a type of negative gravitational potential energy to make total energy conservation work. According to such views, nearly all of the universe's mass condensed out of the vacuum to offset the negative energy associated with the inflationary epoch. As a result, the universe's total energy is zero. It is not the sole hypothesis, but it is useful in that it answers the issue of why there is something rather than nothing. It would imply that there is nothing completely, but it is unevenly dispersed. One of the two major forms of energy is potential energy. Potential energy is the amount of energy that an object can hold. It is the power that a thing has while it is not in motion. The potential energy of a moving item increases as it slows down. The object's capacity strength reduces as it accelerates. Potential energy is the electricity that occurs as a result of the relative locations (configurations) of the components in a physical machine. This energy form has the capacity to modify the state of other things around it, such as the configuration or movement. Potential energy encompasses a wide range of energy kinds.

Which function of the cell cycle is especially important to burn victims? growth of existing cells repair of existing cells protection of new cells reproduction of new cells
Reproduction of new cells are the function of the cell cycle is especially important to burn victims. Hence option d is correct.
What is reproduction?Reproduction is defined as birthing is the process by which a living thing produces offspring. To reproduce is to reproduce. It is a biological procedure by which an organism creates a physiologically identical progeny. Generation after generation, reproduction makes possible and ensures the survival of species.
The phases of the cell cycle are G1, S, G2, and mitosis. In gap 1, the cell expands in size and copies the DNA during the synthesis phase. The cell goes through preliminary modifications in the gap 2 phase. The real division takes place during the mitotic phase, when the cell multiplies and grows in quantity to replace the burned victim's old and dead cells. It encourages the wounded area's growth and healing.
Thus, reproduction of new cells are the function of the cell cycle is especially important to burn victims. Hence option d is correct.

From about 450 to 300 million years ago, bryophytes dominated the earth's vegetation, and then about 300 million years ago, gymnosperms began to become more prominent.
Evolution of plantsAbout 450 to 300 million years ago, most of the plants as we currently have them are yet to evolve according to evolutionists.
Instead, seedless vascular plants such as bryophytes were around. Many years after, these seedless plants evolved into vascular plants with seeds that are not enclosed in fruits.
Vascular plants with seeds but without fruits are known as gymnosperms. Plants whose seeds are enclosed in fruits, angiosperms, evolved thereafter.

Each myofibril is attached at either end of the muscle fiber, when sarcomeres shorten, the muscle fiber Shortens
Mechanism :
Myofibrils are components of the animal skeletal muscles that are made up of sacromeres. They perform the muscular contraction and relaxation via the sliding filament model.
To produce motion, A cross-bridge forms between actin and the myosin heads triggering shortening of the sacromere. This shortening of the sacromere results in the contraction of the muscle fibers, which the net effect can be seen to be a shortening of the fibers.
