Answer:
A) Mitotic spindles form
Explanation:
The mitotic spindle begins to develop during prophase. As the cell's two centrosomes move toward opposite poles, microtubules gradually assemble between them,
Answer:
a
Explanation:
Answer:
Vital capacity can be defined as the maximum volume of air a person can breathe in after a forced expiration. It is equivalent to the sum of expiratory reserve volume (ERV), tidal volume (TV) and inspiratory reserve volume (IRV).
Now, the vital capacity of John would be = 450 + 2600 + 900 ml
= 3950 ml or 3.95 L.
Answer: Dominant: red, recessive: white.
Explanation:
Alleles are different forms or versions of a gene, and they can be described as either dominant or recessive.
Dominant traits are those that are seen in a heterozygous genotype. It means the organisms has two different alleles for a gene, one is dominant while the other one is recessive. A dominant allle dominates over the recessive alleles and it masks the effects of this recessive allele. This means, the offspring only needs to inherit one dominant allele to have a dominant trait.
In the example, a red-flowered plant is crossed with a white-flowered plant. And all plants on the next generation are red. If each plant from this offspring inherites one allele of each parent, they have one red allele and one white allele. Since they are all red, we can say red color is dominant and white color is recessive. Because red allele has a dominant phenotype.
Answer: Condensation.
Explanation:
The process by which the water vapor becomes liquid is known as condensation. The water vapors from the water bodies reaches the sky and then it condenses to form clouds.
The clouds contains water and falls on the earth in the form of precipitation. The precipitation can be in the form of solid(ice) or liquid( rain).
Answer: Forces like wind and water move the rock pieces. They mix with matter like sand to become sediment. Weathering and erosion help shape Earth's surface. They are part of a process called the rock cycle.

Answer: to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.
Explanation:
Answer:
Homeostasis is maintained by a series of control mechanisms functioning at the organ, tissue or cellular level. These control mechanisms include substrate supply, activation or inhibition of individual enzymes and receptors, synthesis and degradation of enzymes, and compartmentalization. For example, to regulate temperature, you will sweat when you get too hot or shiver when you get too cold.
