Which of the following statements is false? - DNA polymerase joins nucleotides in one direction only. - The leading strand of DN
stiv31 [10]

DNA replication proceeds in one direction around the bacterial chromosome.

Explanation:

Replication of DNA is preserved across most of life. Therefore, even bacteria DNA replication occurs bidirectionally. During replication of DNA, A primer is required in the initiation complex before DNA polymersae can begin replication. This is because this enzyme works by adding DNA nucleotides at the 3’ end of an existing strand. DNA can have several replication forks on one double strand in which replication occurs. For every fork, there is a leading strand whereby the replication process by DNA polymerase is continuous and the lagging strand whereby the replication is done in bits by the same polymerase enzymes. The lagging strand will, therefore, require many primers. This is becaue strands of DNA are antiparallel yet the DNA polymerase has to move in one direction. Since replication can only occur in the 5’⇒3’ direction, the antiparallel strand will be done in 5’⇒3’ chunks that will later be joined into one strand.

Compare and contrast the effects of inavasive species, speciation and extinction biodiversity
andreyandreev [35.5K]

Answer:

Modern invasive species are characterized by broad environmental tolerances, which contribute to their ability to survive during both the transport and establishment phases of invasion. Studies of modern and invasive species have demonstrated that invader species regularly displace native species through higher resource efficiency or competitive ability. A striking feature of the biogeographic pattern is the differential survival of species with large geographic ranges. Species with larger geographic ranges tend, on average, to have broader ecological tolerances than those with small ranges.

Sperm are created through meiosis in an area of the testes called the seminiferous tubules. Through which structure do the sperm
Alborosie

Answer:

Epididymis

Explanation:

From the testes, the sperms travel to the epididymis. These structures can be found resting on top of each testes. Fresh out of the testes, sperms are not yet matured and this is where the epididymis takes over. The sperm are stored here and this is where sperm matures. From here, the sperm moves into the vas deferens.
