Mitosis is the division of the _____ and begins with a stage called ____ . As the nuclear envelope finishes dissolving, the cells enter ____, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is ____ . As sister chromatids separate, cells enter ____ and they finish separating and a nucleus reforms around each set of new chromosomes in ____ . During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.
Answer:
cell; prophase. prometaphasemetaphase. anaphase, telophase.Explanation:
Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.

Why might more frequent prescribed burns be easier to control than less frequent burns?
Answer:
Wildfires that burn into areas where fuels have been reduced by prescribed burning cause less damage and are much easier to control. ... The time interval between fires can be as often as every year although a 3- or 4-year cycle is usually adequate after the initial fuel-reduction burn.

Highlighter portion is at the bottom of the brain, forming a connection between the center of the brain and the spinal cord.
Brain stem
Pituitary gland
Cerebrum
Cerebellum
Based on the description provided, the highlighted portion of the brain is the brain stem, which is the first option. The brainstem connects the brain to the spinal cord, and it is located at the base of the brain.
What is the brain?The brainstem is the part of the brain that connects the brain to the spinal cord. It is located at the base of the brain and is made up of three main parts: the medulla oblongata, the pons, and the midbrain.
The medulla oblongata is the lowest part of the brainstem and controls vital functions such as breathing, heart rate, and blood pressure. The pons is located above the medulla and is involved in functions such as sleep, respiration, and facial movements. The midbrain is the uppermost part of the brainstem and is responsible for controlling movements of the eyes and body, as well as processing sensory information.
Hence, based on the description provided, the highlighted portion of the brain is the brain stem, which is the first option. The brainstem connects the brain to the spinal cord, and it is located at the base of the brain.

Which of these is a difference between DNA and RNA?
DNA is found in the nucleus; RNA is never found in the nucleus.
DNA consists of five different nucleotides; RNA consists of four different nucleotides.
RNA is double-stranded; DNA is single-stranded.
DNA contains thymine; RNA contains uracil.
In DNA, adenine pairs with guanine; in RNA, adenine pairs with thymine.
Like DNA, RNA is made up of nucleotides. There are two differences that distinguish DNA from RNA: (a) RNA contains the sugar ribose, while DNA contains the slightly different sugar deoxyribose (a type of ribose that lacks one oxygen atom), and (b) RNA has the nucleobase uracil while DNA contains thymine.

During his first set of experiments, Mendel crossed true-breeding plants that
expressed different versions of a studied trait. For example, he crossed tall
plants with short plants. Based on his results, he said the tall plants exhibited
the dominant form of the trait, plant height. Which of the following best
describes the F1 offspring of this cross?
O A. All were tall.
O B. About 25% were short.
C. All were short.
D. About 25% were tall.
Answer: A. All were tall.
Explanation:
True-breeding plants are plants with completely dominant or recessive genotypes (TT (tall) and tt (short), for this example). He crossed one tall plant with genotype TT with a short plant with genotype tt. Set up a Punnett square with parents TT and tt.
All offspring will have the genotype Tt. T is dominant, so only one copy of it is needed for a plant to be tall. All of the offspring have one copy of T, so they're all tall.
