What do dna microarray assays allow scientists to study regarding gene expression?
Allisa [31]

DNA microarray assays allow scientists to identify networks of gene expression across an entire genome.

The microarray is scanned to determine the expression of each gene printed on the slide after hybridization. The associated spot on the microarray turns red if a particular gene's expression is higher in the experimental sample than in the reference sample.

The DNA microarray is a technology that is used to identify whether a specific person's DNA has mutations in genes like BRCA1 and BRCA2. The chip is made up of a tiny glass plate that is enclosed in plastic. A few businesses use techniques resembling those employed to create computer microchips to produce microarrays.

Which is the order of airflow during inhalation?
Brums [2.3K]

The correct answer is B. Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli

Explanation

The breath of living beings is divided into two processes, the first is inhalation and the second is exhalation. Regarding the first, it is the process in which the air is taken by the beings to be conducted to their lungs through their noses, passing through the nasal cavity, larynx, trachea, bronchi, bronchioles and finally alveoli where gas exchange occurs. The second process is the opposite, in which the air inside the lungs converted into CO2 is expelled, passing through the same places in an inverted manner, that is, alveoli, bronchioles, bronchi, trachea, larynx and nasal cavity. So, the correct answer is B. Nasal cavity, larynx, trachea, bronchi, bronchioles, alveoli.

Oxygen is formed from carbon dioxide in _____(1)_____, while carbon dioxide is formed from oxygen in _____(2)_____.
g100num [7]

Answer:

Oxygen is formed from carbon dioxide in <u><em>photosynthesis</em></u>, while carbon dioxide is formed from oxygen in<u> </u><u><em>respiration. </em></u>

Explanation:

Photosynthesis can be described as the process by which plants make glucose and oxygen from carbon dioxide and water in the presence of sunlight. By this method, plants are bale to make their own food. Cellular respiration can be described as a process by which plants convert oxygen and glucose into water and carbon dioxide along with the release of ATP.  The process of photosynthesis and cellular respiration are opposite of one another and are equally essential.
