Let's calculate the difference in nucleotides. The number of difference multiplied by rate of mutations will help to determine how long ago these two species shared a common ancestor.
Species A: GTACCTAAGTTCACCGAATT
Species B: GAACCTAAGGGCACCGAACT
These species differ in 4 nucleotides.
This number should be multiplied <span>by </span>the rate of mutations
The answer would be A. a virus
The question states that the blood was filtered thru a porous material that prevented <u>all cells </u>from passing thru.
All of the options are cells except viruses.
Hope this helps:)
Its fossils or its nvm its definitely fossils
Dispersal helps different species to increase their range of places, thereby helping to increase their population size in different regions. Dispersal also helps to avoid crowding of diseases of a single location as species move to different locations.
<h3>What is dispersal?</h3>
- Dispersal is the act of distributing things over a large area. It is when the individuals or seeds move from one site to their growing site.
- Dispersal can be active (move by oneself) or passive (require dispersers).
- Seed dispersal is the mechanism of transport of plant seeds to new sites for germination and the establishment of new individuals and colonies.
- This depends upon the effectiveness of the seed dispersers.
- Seed dispersal occurs by wind, water, animals, bats, explosions or gravity of the earth.
- Dispersal of seeds is very important for the survival of plant species.
- If the plants of same type grow too closely, they have to compete with each other for light, water and nutrients from the soil.
- Seed dispersal allows plants to spread out from a wide area and avoid competing with one another for the same resources.
