Answer:species that colonize new surfaces

Explanation: pioneer species are species that first colonize an environment It could be a barren land or a distrupt land that has been abandoned for a long time. some of the environment or soil are usually poor and plants found around such areas have long root and hard to adapt to the environment. Pioneer plant forms the basis of diversity and the initial stage of sucession. Example includes Algae,mosses

Answer:

e) Lamarck

Explanation:

Lamarck stated that traits could be acquired due to the use or disuse of a certain structure, for example: if giraffes were trying to reach leaves this would cause their necks to elongate and the trait would pass onto the next generation in other words organisms could change by what organisms want or need. In the 1880s, the German biologist August Weismann disproved this theory.

How has shark skin been used to inspired materials that slide faster through the water?

sergey [27]

Answer:

Shark skin has been used by many cultures as sandpaper. It's kept shipmates safe in slippery-when-wet conditions. Swimsuits modeled on shark skin are said by Speedo to reduce drag by up to 4 percent. Now, research by two separate groups could lead to synthetic shark skin that would make ships and submarines faster and less expensive to operate.

Interpret the Punnett square. A Punnett square with four rows and four columns. The first row is labeled big-A, big-B. The secon

Naddika [18.5K]

Answer:

The genotypes shown represent gametes. False

One of the possible offspring genotypes is AABB. True

The parent genotypes are ABAbaBab×ABAbaBab. True

This cross shows two alleles for two traits. True

The gametes are diploid and the offspring are diploid. False

The genotypes shown are correct for a dihybrid cross. True

Explanation:

║ AB ║ Ab ║ aB ║ ab

AB║ABAB ║ ABAb║ABaB║ABab

Ab║ AbAB║ AbAb ║AbaB║Abab

aB║aBAB ║ aBAb ║aBaB║aBab

ab║abAB ║ abAb ║abaB ║abab

Drawing the Punnett square we can deduce that the genotypes shown do not represent gametes because there are more than 2 pairs of chromosomes.

As shown in the second column second row of the Punnett square one of the possible genotypes is AABB, it is distributed different (ABAB) but it is the same possible genotype.

The parents' genotypes are the ones that are written in the first columns and first row, they coincide with the ones in the statement.

A dihybrid cross shows the cross between two genes that have different traits.

The gametes are always haploid and the offspring are diploid because the two gametes come together.
