7. How does the plant lichen quicken the weathering process? *

34kurt

Answer:

The correct answer is - They secrete acid that breaks away rocks

Explanation:

Lichen causes chemical weathering to break the rocks quickly which is the excretion of various acids like oxalic acid and many more organic acids that can cause a significant impact on the rock by dissolving minerals.

By breaking the rocks it forms the ground for the plant that will come later in place of the bare rocks by this chemical weathering process. An example of chemical weather is a change of the granite to clay with the help of hydrolysis.

Uma evidente diferença entre as anáfases da mitose e as anáfases I e II da meiose é que os cromossomos em migração para os pólos

vaieri [72.5K]

Translated with google translation, and my knowledge of Portuguese.

An evident difference between anaphases of mitosis and anaphases I and II of meiosis is that the chromosomes migrating to the cell poles are: for the cell poles are: (0.5) *

a) brothers in anaphases I and II and counterparts in anaphase of mitosis.

b) homologous in anaphases I and II and brothers in anaphase of mitosis.

c) homologous in anaphase I and children in anaphase II and anaphase of mitosis.

d) siblings in anaphase I and anaphase of mitosis and counterparts in anaphase II.

e) brothers in anaphases I and II and anaphase of mitosis.

Answer:

C.homologous in anaphase 1 and brothers in anaphase 11 and anaphase of mitosis.

Explanation: for moderator

This simply refers to the differences between the anaphase stage of Mitosis and Meiosis.

At Anaphase of Mitosis,there is centromere division.Therefore the homologous chromosomes separated into sister chromatids at the centromere, with each migrating to opposite poles of the cells.

At Anaphase i of meiosis, there is no centromere division. Homologous chromosomes migrates together to opposite poles lead by centromere.

At Anaphase ii, the homologous chromosomes undergo centromere division into sister chromatids, each migrating to opposite poles, thus behaving independently of one another.

thus Anaphase ii and anaphase of mitosis are the same.(children-Filho sister chromatids, but at Anaphase i, they are homologous since no centromere division..

Explanation for the student in Portuguese

so se refere simplesmente às diferenças entre o estágio anafásico da mitose e da meiose.

Na Anáfase da Mitose, há divisão centrômero. Portanto, os cromossomos homólogos se separam em cromátides irmãs no centrômero, cada um migrando para pólos opostos das células.

Na Anáfase i da meiose, não há divisão centrômero. Os cromossomos homólogos migram juntos para os pólos opostos liderados pelo centrômero.

Na Anáfase ii, os cromossomos homólogos passam pela divisão do centrômero em cromátides irmãs, cada uma migrando para pólos opostos, comportando-se independentemente um do outro.

portanto, a anáfase ii e a anáfase da mitose são as mesmas (cromátides irmãs filhos-filho )mas na anáfase i, elas são homólogas, pois não há divisão do centrômero.

The fruit of a certain plant is sweet and fleshy. The seeds of this plant have a seed coat that is

Ann [662]

Answer:

Animal

Explanation:

The fact that the seed is sweet and fleshy means it attracts animals who ingest it due to its palatability. The animals get to diperse the plant seeds. The acidic environment of the digestive tract of the animals helps soften the seed coat. When the seed is finally excreted by the animal, is can easily germinate.

Onsider the generalized cladogram of fish.

jok3333 [9.3K]

The fossilized fish which is found has jaws but no true bones belonging at point B on the Cladogram. Thus, the correct option is B.

<h3>What is Cladogram?</h3>

A cladogram may be defined as a phylogenetic tree that is based on the classification of evolutionary relationships.

In the given cladogram, D is any ancestral point from which speciation occurs. Point C is a basal taxon while A and B are sister taxons.

The organisms of point B have only jaws bu,t not true bones, while the organisms at point A have both jaws and true bones.

Therefore, it is well described above.
