Answer:
genetic material is exchanged between nonsister chromatids, resulting in new combinations of alleles.During crossing-over, the genetic material is exchanged between non-sister chromatids, resulting in new combinations of alleles. Thus, the correct option is C.
What is Crossing-over?Meiosis is the cell division in which crossing-over takes place. Crossing-over results into formation of recombinants with genetic material which is different from the parental cells. Crossing-over takes place in the pachytene stage of prophase I of Meiosis I. This is responsible for the production of variations in the organisms.
Crossing over or chromosomal crossover is the exchange of genetic material during the sexual reproduction between the non-sister chromatids of two homologous chromosomes which results in recombinant chromosomes.
Therefore, the correct option is C.

Most of the planets that have been discovered using the transit method have had large diameters. Why?
Answer:
Most planets discovered using the transit method have large diameters because planets having large diameters results in a more pronounce (noticeable) dimming effect during their transit between a star and an observer and are therefore readily discovered using the transit method than planets that have a smaller diameter
Explanation:
The transit method involves the detection of a transit (dimming) during the motion of an object between a star and an observer such as the motion of Mercury or Venus between an observer on Earth and the Sun
A large planet gives a higher dimming effect than a small planet and they are therefore more easily detectable using the transit method
The transit method is the method used to discover most of the known exoplanets which are planets that revolve around a star which is not the Sun
As the planet transits in front of a star in an observer's line of sight, it results in the dimming of the stars light by an amount equivalent to the ratio of the planet's to the star's circular areas
Example of planets discovered using the transit method includes the planet HD209458b.

What are the inputs and outputs of cellular respiration and photosynthesis?
Answer:
Respiration is the reverse reaction of photosynthesis.
Explanation:
The inputs of cellular respiration are oxygen and glucose and the outputs of cellular respiration are energy in the form of ATP, water and carbondioxide while on the other hand, the inputs of photosynthesis are water and carbondioxide and the outputs of photosynthesis are glucose and oxygen. Glucose is stored in the body whereas some oxygen is used in the process of respiration while the rest is released in the atmosphere.

What is the difference between carnivores and herbivores?The three diets of animals include creatures that eat only plants, those that eat only meat, and animals that eat both plants and meat. Animals that eat plants exclusively are herbivores, and animals that eat only meat are carnivores.
Herbivores animals have broad, flat and short, teeth to grind and chew plant leaves, grains, and seeds. Carnivores animals possess long, sharp, and curved incisors and canines to tear flesh.
Teeth are suited for eating plants as well as meat. Deer, goats, zebras, etc. are the examples of the herbivores. Carnivores animals are lions, tigers, dogs, etc.

One letter from each parent are combined to create a genotype of one possible offspring. Example: G (from one parent) + g (from the other parent) = Gg (genotype of offspring)
Capital letters are dominant and lowercase letters are recessive
Dominant traits mask recessive ones so when the genotype of the offspring is Gg, it will be green because green is dominant over yellow

Answer:
Rainforests are the Earth's oldest living ecosystems.
They are so amazing and beautiful.
These incredible places cover only 6 %of the Earth's surface but yet they contain MORE THAN 1/2 of the world's plant and animal species!
A Rainforest can be described as a tall, dense jungle. The reason it is called a "rain" forest is because of the high amount of rainfall it gets per year. The climate of a rain forest is very hot and humid so the animals and plants that exist there must learn to adapt to this climate.
Rainforests basically have four layers to them.

As many as 30 million species of plants and animals live in tropical rainforests.
At least two-thirds of the world's plant species, including many exotic and beautiful flowers grow in the rainforests.
This pink plant grows on rainforest trees - it is an epiphytic air plant which means it grows on the tree but is not a parasite.

Riscuess what kind of georgespgic barries would have led to the flinch speciation in the Galapagos
Answer:
Rivers change course, mountains rise and continents drift.
Explanation:
Rivers change course, mountains rise and continents drift are the geographic barriers that have led to the flinch speciation in the Galapagos because these barriers separated finch species from one another. Due to these geographic barriers, finch species have different body structure and features. These geographic barriers prevent two finch species from interbreeding with one another which leads to flinch speciation.

How does the shape of vomerine teeth help it preform its function?(holding prey) This question is about frogs in case there is any confusion
Answer:
The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.
Explanation:
In frogs, we can distinguish maxillary teeth, premaxillary teeth, and Vomerine teeth.
Vomerine teeth are projections of the vomer bone, located in the anterior part of the paladar and between the internal nares.
Vomerine teeth are specialized structures that help frogs catch and hold their prey. They are not involved in chewing or killing (frogs swallow the entire prey alive), just holding the creature before swallowing it.
These projections are covered by soft tissue. When the frog catches the prey, presses the tongue against the roof of your mouth. The vomerine teeth hook the prey and prevent it from slipping or wandering away.
The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.

Answer:
The Meiosis Cell Cycle
Explanation:
Cell cycle is the process if cell division. The end product of cell cycle is two genetically identical daughters cells produced by cell division.
What is cell cycle?Cell cycle is the process occurring through different stages by which a cell divides to form its daughter cells. Various enzymes have significant roles in cell cycle.
A large number of DNAs in the chromosome of a cell undergo division where, the double stranded DNA separate and and each strand forms two new DNAs.
Therefore, at the end of a cell cycle through proper cell division, two genetically identical daughters cells are produced.
