Which of the following is a major trend in land plant evolution? Group of answer choices the trend toward a gametophyte-dominate

Leviafan [203]

Answer:

trend toward a sporophyte-dominated life cycle

the trend toward larger gametophytes

Explanation:

<em>The major trend in the evolution of land plants is the domination of the sporophytic phase in the life cycle and alternation of generation. It also moves towards a larger gametophytes</em>

In lower plants, the gameophyte phase was dominant in the life cycle while in bryophyte, both gametophyte and sporophyte phase are co-dependent.

The sporophyte phase is the diploid phase while the gametophyte phase is the haploid phase.

Also, the gameotyptic stages are quite microscopic (usually in the form of spores) in lower plants while they become bigger in land plants (in the form of ovary and pollen) although with fewer cells.

Answer no 1:

sW sW sw sw

Sw SsWw SsWw Ssww Ssww

sw ssWw ssWw ssww ssww

The genotype of the parents will be Ssww and ssWw.

About 4/16 offsrings will have the genotype SsWw, 4/16 will have the genotype Ssww. 4/16 will have the gentype ssWw. 4/16 will have the genotype ssww.

About 25% will have the phenotye, smooth and wooly. About 25% will have the phenotype smooth and non wooly. About 25% will have the phenotype non- smooth and wooly. About 25 % will have the phenotype non-smooth and non- wooly.

Answer No 2)

bT bT bT bT

Bt BbTt BbTt BbTt BbTt

The genotype of the parents will be BBtt and bbTT.

As seen in the punnet square, the phenotype of all the offsprings born from such a cross will be black trotter.

Answer No 3)

wd wd wd wd

WD WwDd WwDd WwDd WwDd

The genotype of the parents will be WWDD and wwdd.

The results of the punnet square illustrate that all of the offsprings will have white flower colour and disc shaped fruit.

Answer No 4)

The phenotypes of the rabbits will be as follows:

Ggbb - Gray hair and red eyes.

ggBB- White hair and black eyes

ggbb - White hair and red eyes.

GgBb - Gray hair and black eyes

Answer No 5)

Gb Gb Gb Gb

gB GgBb GgBb GgBb GgBb

gb Ggbb Ggbb Ggbb Ggbb

8 out of 16 offspring will have Gray fur and black eyes.

8 out of 16 will have gray fur and red eyes.

0 out of 16 will have white fur and black eyes.

0 out of 16 will have white fur and red eyes.

Griffin performed experiments demonstrating that when live, nonpathogentic, S. pneumoniae (which produce rough-surfaced colonies

bekas [8.4K]

Answer:

Transformation

Explanation:

The experiment of Griffith on S. pneumoniae leads to the conclusion that the bacteria can take the DNA from the surrounding environment by the process of "Transformation".

He selected the two strains of bacteria, the smooth pathogenic strains (S strains) and the rough non-pathogenic strain (R strains). When he injected the dead S bacteria and live R bacteria, he obtained the live S bacteria from the mice.

He was amazed at how the dead S strain bacteria became alive and concluded that the dead S strain bacteria were transformed into the live S strain bacteria and named the process transformation. The transformation process refers to the uptake of the DNA material from the surrounding environment.

Thus, transformation is the correct answer.
