Skepticism is based off of invalid data or an experimental error, but in this case the scientist is being biased.
B) savanna
C) taiga
D) tundra
Answer:
[B]
Explanation:
The savanna biome makes up half of the surface of Africa. The biome is mabe up of mostly grasses and few scatted trees. Since the desert has nlittle to no grass and the taiga biome is the smallest in Africa and has little grass, while tundra biome is also small to non-existent in Africa. The perfect answer is B for savanna biome.
When you heat up an object, the particles in the object move away from the heat source. The heat energy form the source transfers to the particles which causes them to be excited to move and go in any direction away from the source. It increases the kinetic energy of the particles.
Answer:
a
Explanation:
if a cell is without water it has a high salinity while fresh water doesnt so the water rushes in and burst the cell
The right answer is Change in color, production of gas, formation of precipitate.
Chemical changes alter the nature and characteristic properties of matter. New substances are formed as a result of the reaction.
It is said that a pure substance has undergone a chemical change if it has been transformed into one or more new pure substances which do not have the same properties as the starting substance.
The characteristic properties of the substances disappear and the products formed have new properties.
There are several (even more than three) that can recognize the presence of a chemical change.
* The formation of a gas (effervescence)
* Production or absorption of heat
* The production of bright light
* A significant color change
* A change of smell
* The formation of a precipitate
Answer:
Metaphase
Explanation:
The M phase of the cell cycle is the phase during which the nuclear content and cellular content is distributed. The distribution of the nuclear content takes place in four phases: prophase, metaphase, anaphase and telophase.
The homologous chromosomes are aligned at the equatorial plate during the metaphase after which the chromosomes separate. The phase during which the separation of the chromosomes takes place is known as anaphase so the phase before the anaphase is the phase during which the chromatids are not separated that is the metaphase.
Thus, metaphase is the correct answer.
In mitosis, the last phase where chromatids are together is the metaphase. After this, during the anaphase, sister chromatids separate and move towards opposite poles.
In mitosis, the last phase where chromatids are together is the metaphase. During this stage, chromosomes line up across the centre of the cell and each chromosome is connected to a spindle fibre at its centromere. This ensures equal division of chromosomes into each of the two new cells. After the metaphase, during anaphase, the centromeres of each chromosome separate and the sister chromatids move away from each other towards opposite poles.
