If the cell is green, that would mean that it contains the pigment of chlorophyll (suggesting that it is a plant cell). In addition, a rigid cell wall means the cell is part of a stronger structure, so it is likely a plant cell.
First answer is A
Second answer is C
Absence of oxygen means anaerobic respiration ; which has 2 different pathways.
First Pathway ; Alcoholic fermentation which takes place in yeast.
Pyruvate is decarboxylated into ethanal releasing co2 as waste product.
Ethanal is toxic , so its reduced by help of NADH to ethanol in presence of alcohol dehydrogenase enzyme , and Free NAD is released to continue glycolysis.
2) The second pathway is Lactic fermentation which takes place in mammalian muscles.
Pyruvate accepts hydrogen and is converted to lactate by the help of enzyme lactate dehydrogenase , again free NAD is released to continue glycolysis.
Hope I made it clear enough :)
Answer:
Insecurely attached.
Explanation:
Infants that are insecurely attached have learned that adults are not to be trusted. Children who have had negative encounters with their caregivers tend to develop insecure attachment.
Children with insecure attachment refuse to associate with others, show fear and anger.
Answer:
Azidothymidine
Explanation:
Azidothymidine (AZT) is one of the nucleoside analogs that is used in the treatment of AIDS as it inhibits the process of reverse transcription of HIV (Human immunodeficiency virus).
The HIV replicates by making DNA copies of RNA through the process of reverse transcription. The process is driven by enzyme reverse transcriptase. Azidothymidine (AZT) serves to inhibit the activity of reverse transcriptase enzyme and thereby does not allow HIV to reproduce.
