15. Meiosis II occurs to reduce the number of chromosomes and become gametes.
16. False, chromosomes do not form pairs in prophase II.
17. True, sister chromatids split up in anaphase II.
What happens in anaphase II?Sister chromatids separate and are pulled to opposite poles of the cell during anaphase II. At the centromere, the chromatids split. They are then referred to as non-replicated chromosomes. Spindle fibers transport chromosomes to the poles. Each pole receives 23 chromosomes.
Since meiosis generates cells that will become gametes (or reproductive cells), this reduction in chromosome number is critical; without it, the union of two gametes during fertilization would result in offspring with twice the normal number of chromosomes.

Answer:
Not a copy and paste answer
Explanation:
When resources are limited in an habitat, organisms with heritable traits favor more survival and reproduction will tend to leave more offspring then other organisms only because of their heritable traits.

PHET Energy Skate Park Simulation .Consider this equation: gravitational potential energy = mgh. Which of those variables is changing as the skater moves up and down the track?
Answers
Answer:
h - height
Explanation:
gravitational potential energy = m * g * h
m stands for mass. Mass doesn't change in physics
g stands for gravitational acceleration. It is a constant.
h stands for height. When the skater moves up and down the track the height from the ground changes. Therefore this variable does change.
In the equation gravitational potential energy = mgh, the variable that is changing as the skater moves up and down the track is the variable h, which represents the height or vertical position of the skater.
As the skater moves up the track, the height increases, resulting in a higher value for h. Conversely, as the skater moves down the track, the height decreases, leading to a lower value for h.
The other variables in the equation, m (mass) and g (acceleration due to gravity), typically remain constant unless specified otherwise. Therefore, the changing variable in this equation as the skater moves up and down the track is the height (h).

New World monkey D. Old World monkey
Answers
Answer:
C
Explanation:yeah
The correct answer is New World monkey as is observed in South America. It has a prehensile tail, spends most of its time in the trees, and is fairly small.
On one hand, a few species of New World monkeys own prehensile tails, which means they are able to use their tails to understand or maintain directly to objects (2). Their tails can resource those monkeys in locating and consuming meals withinside the cover in addition to transferring among the trees, as their tails offer greater help and balance.
The formal time period for the taxonomic organization containing all of the New World Monkeys (NWMs) is Platyrrhini. The NWMs diverged from the Old World monkeys and apes (Catarrhini) round forty million years ago (Perelman et al. 2011). Ancestral species are idea to have migrated to the Americas on rafts of plants or through island hopping (Fleagle 2013). The extant species of NWMs are presently labeled into 5 families, twenty genera, 156 species, and 204 taxa. However, the taxonomy of numerous taxa is debated withinside the literature and, therefore, this type is concern to change.
What is the New World monkey living area?
Many of the monkeys scampering across the forests of Central and South America have some thing unique on their butts-- a further hand. Well, now no longer exactly. It's a prehensile tail-- a greedy appendage that enables the animals navigate the tall and treacherous cover on the lookout for end result and leaves .
Hence concluded that the New World monkey have a prehensile tail, spends most of its time in the trees, and is fairly small.

Taking into account the definition of Avogadro's number, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.
Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance.
Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of moles in this caseIn this case, you have 2 moles of Fe(NO₃)₂.
Then you can apply the following rule of three: If 1 mole of the compound contains 6.023×10²³ molecules, 2 moles of the compound contains how many molecules?
amount of molecules= (6.023×10²³ atoms× 2 moles)÷ 1 mole
amount of molecules= 1.2046×10²⁴
Finally, 2 moles of Fe(NO₃)₂ contains 1.2046×10²⁴ molecules.

the connection between limiting factors and invasive species
Answers
Answer:
Biology, Ecology, Earth Science, Climatology, Geography
Explanation:
A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. Others are abiotic, like space, temperature, altitude, and amount of sunlight available in an environment. Limiting factors are usually expressed as a lack of a particular resource. For example, if there are not enough prey animals in a forest to feed a large population of predators, then food becomes a limiting factor. Likewise, if there is not enough space in a pond for a large number of fish, then space becomes a limiting factor. There can be many different limiting factors at work in a single habitat, and the same limiting factors can affect the populations of both plant and animal species. Ultimately, limiting factors determine a habitat's carrying capacity, which is the maximum size of the population it can support
