What does it mean that there is both unity and diversity of life?

Hi there!

By both unity and diversity in life, it means that animals and plants (and ecosystems) can be very different from each other but they can also have very similar characteristics. They can work together in harmony but become predator and prey at the same time.

Hope this helps!

Unity is: all life requires DNA, all like requires a source of energy whether it be autotrophic or heterotrophic, all life must must be able to reproduce. all living things consist of one or more cells

Diversity: many many many different forms of DNA, many different types or organisms divided in kingdoms, phylums and so forth. the are mammals the are insects their are clams all with very different anatonomys. Their are different habits an organism can survive in, some organisms live in the ocean some on land, the list gots on and on

I hope that helps

The chief force pushing things out of the blood, through the filtration membrane and into the nephron is:______.

GrogVix [38]

The hydrostatic pressure in the glomerular capillaries is the chief and force pushing the water and the solutes out of the blood and to across the filtration membrane.

The glomerulus was the filtering unit of the kidney, which s a unique bundle of the capillaries and lined by the delicate fenestrated and endothelia, a complex mesh of the proteins that serve as a glomerular the basement membrane and the specialized visceral epithelial cells that also form the slit diaphragms and in between the interdigitating foot processes

The glomerular capillaries are basically the barrier to the distribution of the large plasma proteins and into urine. the Large proteins such as the albumin and IgM are impeded by the capillaries whereas smaller proteins pass through the filtration barrier into the tubular fluid.

HELPP!!

I would say it is answer c.
- In gymnosperms (plants with “naked seeds”—such as conifers, cycads, and ginkgo), the ovules are not enclosed in an ovary but lie exposed on leaflike structures, the megasporophylls.

How could Flor explain why all three species share some body structures and have some differences? Why do only house geckos and

defon

The similarities in the structure of the three species is due to their sharing a common ancestor while the differences is due to adaptation.

<h3>What is divergent evolution?</h3>

Divergent evolution is evolution where individuals who shared a common ancient ancestor process to have differing structures due to differences in their habitats.

All three species that Flor observed having similar structures is because they had a common ancestor.

The species had differences because they evolved to adapt to their different environments.

Wall geckos and Pacific gulls have temporal holes in their skulls as adaptations to their habitat.

Assume DNA replication proceeds at a rate of 100. base pairs per second in human cells and origins of replication occur every 30

ivolga24 [154]

Answer:

The replication of DNA takes place at different frequencies on the basis of the kind of enzyme monitoring the process. There are five distinct enzymes that catalyze the reaction, these are, alpha, beta, gamma, delta, and epsilon. They all possess distinct rates of replication on the basis of the number of nucleotides.

If DNA replication progresses at a rate of 100 base pairs per second and the origin of replication is found at every 300-kilo base pairs. A diploid human genome comprises 6 × 10^9 base pairs of DNA. The number of replication forks can be determined by using the formula:

N = 6 × 10^9 nt/genome / 300 × 10^3 bp/origin

= 2 × 10^4 origins (2 replication forks / 1 origin)

= 4 × 10^4 replication forks

Here, N is the number of replication forks, nt are nucleotides. Thus, the number of replication forks found in the given length of the genome is 4 × 10^4 replication forks.

It has been assumed that the replication of DNA proceeds at a rate of 100 base pairs per second, then the rate of replication can be determined by:

t = 6 × 10^9 bp / 4 × 10^4 replication forks × 100 bp/sec

t = 1500 seconds

It has been assumed that there are two DNA polymerase molecules taking part per replication fork, then the number of DNA polymerases needed for 4 × 10^4 replication forks are as follows:

4 × 10^4 replication forks × 2 DNA polymerase/replication fork

= 8 × 10^4 DNA polymerase.

Thus, the cell would need a sum of 80,000 DNA polymerase molecules for the completion of replication in 4 × 10^4 replication forks.
