does not use oxygen but tolerates it.
Explanation:
The term aerotolerant anaerobe refers to an organism that. does not use oxygen but tolerates it.
Answer: B. False
Explanation:
“Hox” genes are a highly conserved group of genes, all of whose products are transcription factors bearing a specific domain (called a ”homeodomain”). The transcriptional activity of a large amount of genes relevant to embryonic development is controlled by regulatory sites which are able to bind to this domain. Changes in the transcriptional activity of even a single Hox gene may thus have dramatic downstream effects on the phenotype, as this will result in several further genes having their transcription either enhanced or suppressed.
Flowering plants are the most successful land plants because theri seeds are protected in fruits
The answer is upside-down. Mud cracks spread downward keen on soft sediment. When more sediment is eroded in, this second layer will seal the cracks underneath. Later, after the layers have toughened, the rock may be rotated upside-down and then the layers cracked. If you see edges in a mud-crack pattern, you are seeing at the side of the second layer that initially was down. You can tell that this shows edges, and not holes, through the shadow, the edges have a well-lit on one side and a shadow on the other, while holes have light and shadow on the similar side.
