Answer:

A pteridophyte is a vascular plant that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails, and lycophytes are all pteridophytes.

Drag each Moon phase to the correct location on the image.

ruslelena [56]

The correct order of the given moon phases starting with new moon is new Moon, waxing crescent Moon, first quarter Moon, waxing gibbous Moon, full Moon, waning gibbous Moon, last quarter Moon.

<h3>What are Moon phases?</h3>

This cycle has been divided into four primary Moon phases: New Moon, First Quarter, Full Moon, and Last Quarter. Waxing Crescent, Waxing Gibbous, Waning Gibbous, and Waning Crescent are the four secondary phases.

The missing image of the question is attached at the last.

Thus, this way the lunar phases can be placed in the correct order.

Choose the true statement(s) about mutations. To be marked correct, you'll need to select all true statements, as there may be m

Kazeer [188]

Answer

All four options ( A,B,C,D ) are true about mutations.

Explanation:

A- <u>Mutation can provide an evolutionary benefits</u>

As mutation helps in creating DNA sequence ,new allele(variant of gene) for a specific gene , thus mutations is known to be the first step of evolution.

B-<u> Mutation leads to genetic and phenotypic variation within the species. </u>

In mutation, genetic variation (difference between individual/population) takes place as new alleles are created ,random matings ,fertilization and during meiosis , recombination of homologous chromosomes. One of the type of mutation called gene mutation give rise to genetic variations.

Its an exceptional case of phenotypic variations ,as mostly there is no effect of mutation on phenotypic variation. Very few mutations lead to phenotype variation and in case mutation takes place in phenotype variation ,making the organism well suited to the environment, the a rapid change in the characterstics of the individual species is seen.

C- <u>In humans, the somatic cell mutation are not passed in offsprings. </u>

Somatic cells are present in all over the body except in the cells that give rise to gametes( ie. egg and sperm cells) and produces offsprings . Thus somatic cells are absent in gametic cells ,therefore mutation cannot be passed to human's offsprings or children.

D- <u>Evolution rates are faster in bacteria than in humans because most mutations in human cells are silent. </u>

Due to their fast growth ,bacteria evolve quickly and share genes with each other and even between the species ,also the mutation that are helpful spread faster in bacteria.

In humans, the silent mutation in human cells cause many genetic disorders like Laron dwarfism. About 99.8% genes are silent mutation.
