Which stage of mitosis occurs the least often and why?
Explanation:
The Anaphase stage is the shortest phase of mitosis. During this phase, disjunction occurs, and migration of sister chromatids away from each other to the poles of the cell occurs, leading to the formation of daughter chromosomes. Molecular motors use ATP to shorten the spindle fibers attached to each sister chromatid

A student prepares for a five-mile run so she eats a nutritious meal three hours before the run. Which correctly illustrates the transformation of energy from eating the meal to the five-mile run?
Answer: The transformation of energy from eating the meal to the five mile run is from
Chemical energy --> kinetic energy--> thermal energy.
Explanation:
In nature, energy exists in various forms. These forms are inter- convertible, that is, one form of energy can be transformed into another form. Such energy transformations are governed by the laws of thermodynamics.
The first law of thermodynamics states that energy cannot be created or destroyed but may be transformed from one form into another.
Living organisms which comprises the biotic components of an ecosystem are energy converters. For example:
--> plants convert solar energy into chemical energy during photosynthesis
--> animals convert chemical energy into kinetic energy when they move about. This in turn is lost as heat energy when highly complex organised food molecules are broken down.
From the question, the student ate a nutritious meal ( CHEMICAL energy) which is converted to KINETIC energy as she took a five miles run ( as she worked). 'Work' here refers not only to physical activities but also to the various metabolic processes necessary to maintain life. And each time work is done, kinetic energy is converted to heat( thermal energy)

Answer:
1a. To collect and remove waste materials from the body.
2c. Urinary bladder.
3d. Urea
4c. Remove urea and excess water.
Explanation:
The main function of our excretory system is to collect and remove waste materials from our body because these waste materials are toxic and cause damaged our body. Urinary bladder is the organ that stores urine. Urea is present in the urine under normal conditions of the body which is waste material produced our body. The main function of kidney is to remove urea and excess water from our body.

Which statement best explains how the gases of the atmosphere affect the temperature of Earth?
The atmosphere today contains more greenhouse gas molecules, so more of the infrared energy emitted by the surface ends up being absorbed by the atmosphere. Since some of the extra energy from a warmer atmosphere radiates back down to the surface, Earth's surface temperature rises.
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?
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).

Which statement is true regarding the taxonomic system?
Charles Darwin was the primary creator of the current taxonomic system.
All of the past, extinct species have been cataloged.
The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

Explanation:
how do organisms with many cell types develop from a single cell
Cell division, torso axis formation, tissue and organ development are all part of development, and cell differentiation refers to acquiring a final cell type identity.
What is cell division?The process by which a parent cell divides into two daughter cells is known as cell division.
Cell division is usually part of a larger cell cycle during which the cell grows and replicates its chromosomes before dividing.
Cell division occurs in two stages: mitosis and meiosis. When most people say "cell division," they're referring to mitosis, the process of creating new body cells.
Meiosis is the process by which egg and sperm cells are formed. Mitosis is a necessary process for life.
Multicellular organisms form in a variety of ways, including cell division and the aggregation of many single cells. Colonial organisms form when many identical individuals band together to form a colony.
Thus, this way, organisms with many cell types develop from a single cell.
