Answer:

C. Photoautotrophs-oxygenic.

Explanation:

LUCA is an abbreviation of the ‘Last Universal Common Ancestor’. The LUCA was a microorganism which lived around 4 billion years ago. The evidence had shown that the LUCA was lived deep underground in hydrothermal vents. These vents were rich in iron-sulphur. It did not use air but made its food from the metal-rich environment surrounding it. It made organic compounds such as ammonia for its metabolism from elements such as hydrogen, carbon dioxide and nitrogen.

To help sort out those bacteria that have the vgp gene, scientists first attempt to grow the bacteria both in a medium with ampi
ella [17]
Bacteria with no plasmid will ONLY grow in medium without ampicillin. This is because bacteria without any plasmid do not have the gene for ampicillin resistance (ampR). Therefore they can only survive and grow in medium without ampicillin.
Bacteria with nonrecombinant plasmid will grow in both media.According to the image, this type of bacteria has the gene for ampicillin resistance (ampR) in their plasmid. Therefore, they are not affected by the presence of ampicillin in their environment and they can grow in both media.
Bacteria with recombinant plasmid but no vgp gene will grow in both media. These bacteria also have the gene for ampicillin resistance in their plasmid, therefore they can survive and grow in both media.
Bacteria with recombinant plasmid with vgp gene will grow in both media. These bacteria, apart from having the vgp gene in their plasmid, they also have the gene for ampicillin resistance. The vgp gene does not affect the expression of the ampR gene, therefore these bacteria are also ampicillin resistant.

JulijaS [17]

Answer:

The correct answer is "34".

Explanation:

The ant Myrmecia pilosula is a special case of sexual reproduction, where the females produce gamete cells with half the chromosomes of the somatic cells and the males are haploids that transmit the whole number of chromosomes in their gametes. Therefore, the somatic cells of the hybrid female offspring that results from the cross of a female ant with 48 chromosomes and a male with 10 chromosomes would have 34 chromosomes. This result from half the number of chromosomes of the female (24) plus the total number of chromosomes of the male (10).
