The Nervous System is one of the first systems to develop during the embryonic period. Why do you think this is?

The nervous system can be very important. Example: if your finger got caught on a door, your nervous system reacts and sends a message to the brain and then the brain would do the work and tell what to do and send a message back to the finger that got caught and then the finger will pull out.

I mean the nervous system is the one that feels the pain so...

Drag the tiles to the correct boxes to complete the pairs.

Yuki888 [10]

Answer:

1st field: linguistic intelligence

2nd field: visual-spatial intelligence

3rd field: bodily-kinesthetic intelligence

Explanation:

There is a theory called multiple intelligence theory, which suggests that there are several types of intelligence differently proportionally distributed in every person. One of them is linguistic intelligence. Persons who possess it are extraordinary at using and understanding words, written or spoken. On the other hand, persons with visual-spatial intelligence show ability to memorize images, faces, details, also, they're aware of their surroundings and find it easy to orient in new and unknown spaces. Also, there is a bodily-kinesthetic intelligence. People who possess it have great motor abilities, especially fine movements, muscle coordination, body shape and strength which makes them great in using their body movements for expressing ideas, opinions, emotions.

How are abiotic factors are impacting the biotic factors of the Norway arctic ecosystem?

Maintaining the integrity of the stock reagents is a constant concern in the lab environment. Read the situations and decide if

Anarel [89]

Answer:

Question is incomplete i have added full question at the end of this answer because im not able to add it in ask for detail section.

Answer:

1. Contaminate (Because NaOH is a base while H2SO4 is an acid. If student mix both this will result in chemical reaction.)

2. Contaminate (Because returning regents are used already id used regents put back in the bottle it will contaminate the fresh reagents.)

3. Contaminate (Using same spatula without sanitation results in mixing of one reagent into other regents which results in failure of experiments.)

4. Does Not Contaminate (It does not have any effect on the reagent because solid reagents are weighted that can be cleaned off when poured into reaction flask.)

5. Does Not Contaminate (Because washing flask after each experiment will wash off the left reagents present in flask.)

6. Contaminate (This will result in contamination because potassium iodide (KI) solution will be mixed with waste)

FULL QUESTION

Maintaining the integrity of the stock reagents is a constant concern in the lab environment. Read the following situations and decide if each represents a valid contamination concern.

1. A student uses a pipet designated for the NaOH solution to pipet the H2SO4 solution.

2. Several students have left-over reagents after the completion of an experiment and decide to return the excess reagents to their original containers.

3. Only one spatula is available to measure out several different white powders.

4.Rather than wasting multiple weigh boats, a student decides to wash and dry a single weigh boat in-between uses.

5. A group of students must use the same 500 mL volumetric flask to make solutions. Between each use they wash and dry the flask.

6. At the end of the day, the waste bottle is so full that a student decides to dump his waste into an almost empty bottle of stock KI solution.

Identify the major structures within the brain associated with generating and coordinating motor signals for body/skeletal muscl

Temka [501]

Answer:

2Major Structures and Functions of the Brain

Publication Details

Outside the specialized world of neuroanatomy and for most of the uses of daily life, the brain is more or less an abstract entity. We do not experience our brain as an assembly of physical structures (nor would we wish to, perhaps); if we envision it at all, we are likely to see it as a large, rounded walnut, grayish in color.

This schematic image refers mainly to the cerebral cortex, the outermost layer that overlies most of the other brain structures like a fantastically wrinkled tissue wrapped around an orange. The preponderance of the cerebral cortex (which, with its supporting structures, makes up approximately 80 percent of the brain's total volume) is actually a recent development in the course of evolution. The cortex contains the physical structures responsible for most of what we call ''brainwork": cognition, mental imagery, the highly sophisticated processing of visual information, and the ability to produce and understand language. But underneath this layer reside many other specialized structures that are essential for movement, consciousness, sexuality, the action of our five senses, and more—all equally valuable to human existence. Indeed, in strictly biological terms, these structures can claim priority over the cerebral cortex. In the growth of the individual embryo, as well as in evolutionary history, the brain develops roughly from the base of the skull up and out ward. The human brain actually has its beginnings, in the four-week-old embryo, as a simple series of bulges at one end of the neural tube.
