Agroup of scientists sequence and identify various regions of an organism’s genome and find that 92% of the genome (a circular chromosome and a plasmid) is comprised of protein-coding genes. the organism is most likely a?

Bacteria

Explanation:

Bacteria contain all their DNA in a single circular chromosome. Bacteria also contain other smaller circular DNA molecules called plasmids, which can be obtained from other bacteria -through a process called conjugation- or from the environment.

Bacterial genomes are smaller than eukaryotic genomes, and unlike eukaryotes, most of the bacterial genome is coding.  In most species of bacteria there is no non-coding regions between exons.

the level of progesterone is low at the pre-ovulatory phase of the cycle but it gradually increases and the levels are high at the luteal phase. if pregnancy occurs, the level of progesterone will be high throughout the pregnancy.

if egg is fertilized and the mother gets pregnant, progesterone starts preparing the uterus for the implantation. it starts building up the lining of uterus and make it hostile of the period of pregnancy.

he forelimbs below belong to four species that descended in a direct line from the ancestral mammal shown above. of the four descendants shown, which species most likely appeared earliest in evolutionary history?
