Answer: With the development of powerful microscopes, scientists discovered many single-celled organisms that didn't fit into any of Linnaeus' kingdoms. As a result, a new taxon, called the domain, was added to the classification system.
Explanation:
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.

A. The heart rate stops.
B. The heart rate gets slower.
C. The heart rate gets faster.
D. The heart rate stays the same.
Answer: C. The heart rate gets faster.
Explanation:
its true also give brainliest
The heart rate gets faster
Explanation:
C. Because when you are sitting your heart rate is chill put if you're moving really fast that means your heart rate is going up because you have to deep breaths over and over when you stop running.

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.
Explanation:
Hope it helps! Correct me if I am wrong!
I'm sure about my answer!

What is the difference between Gene Pool, Genetic Drift and Gene Flow?
Answer:
Genetic drift is referred to the changes in allele frequency in a gene pool. Gene flow is the process of alleles moving from one population to another.
Explanation:
How might a wildfire influence mass wasting? By drying out (removing the water) from the regolith on a slope, wildfires decrease the likelihood of a mass wasting event. A wildfire can dry out the regolith on a slope, making it less cohesive and more likely to travel downward. Wildfires burn only at the bottom of a slope, which oversteepens the slope and induces mass wasting. The ash from the wildfires lands on the slope, adding enough mass to instigate mass wasting. Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Answer:
Because plants on a slope bind the regolith with their roots and shield the soil surface from raindrops, a wildfire that destroys these plants would render the soil looser and more susceptible to the erosional forces of rain.
Explanation:
The plants present in a region, protect the soil from being eroded by the impact of rain or wind. This is because the roots of the plants leave the soil more aggregated, block the impact of the wind and allow water to infiltrate. This protection is increased on slopes, where the chances of erosion are greater. However, when a fire occurs and these plants are killed, the roots no longer provide protection to the soil, leaving it drier and looser. This causes the wind to break this soil apart, facilitating erosion. In addition, rainwater has difficulties in infiltrating the soil and ends up draining, taking parts of the soil with it and causing erosion.

Genetic Diseases are very common.
Answer:
Cystic Fibrosis is a chronic, genetic condition that causes patients to produce thick and sticky mucus, inhibiting their respiratory, digestive, and reproductive systems. Like Thalassemia, the disease is commonly inherited at a 25 percent rate when both parents have the Cystic Fibrosis gene.
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.

What part of the brain is highlighted in the diagram below?
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.

The moray eel and grouper fish hunt together. When both hunt together, prey barely stands a chance: hide in the reef, the eel eats you; dash for open water, the grouper grabs you. Which symbiotic relationship is described above?
A. Coevolution
b. Mutualism
c. Parasitism
d. Commensalism
Answer:
We can immediately cross-out C
We can also cross-out A.
Now we have B and D. Commensalism and Mutualism. Now, commensalism is an association between two organisms in which one benefits and the other derives neither benefit nor harm.
Mutualism is the doctrine that mutual dependence is necessary to social well-being.
I would say D: Commensalism. Both fish can survive without each other.
