What structure is most important in forming the tetrads?

Vladimir79 [104]

Answer:

The correct answer will be option- synaptonemal complex.

Explanation:

The tetrad arrangement of the genetic material in an organism is mediated by a highly conserved structure known as the synaptonemal complex. The synaptonemal complex is formed during the prophase I of the meiosis I which attaches the chromatin of the homologous chromosomes.

The synaptonemal complex is a proteinaceous structure which is formed by the two lateral ladders like elements with a central portion composed of the central element. The chromatin gets attached to the lateral elements while the central a portion bridge space between the two ladders thus help in the formation of the tetrad.

Thus, option- synaptonemal complex is the correct answer.

Why virus, virions, prions have no place in five kingdom classification

Ainat [17]

Hey, there!!

There is no place for virus, virions, prions in kungdom classification. The reason is they show both living and non living characters, which don't define them whether they are living beings or non living things.

As in 5 kingdoms, the only living organisms are classified.

Kingdom Monera mostly deals with the organism which contains prokaryotic cells.
Kingdom Protista deals with the organism which have eukaryotic cells.
Kingdom Fungi deals with various fungal organism.

So, you can see that there is non of the kingdoms which deals with the organism which have similar characteristics like viruses, virions and prions.

A seasonal color change helps animals in the taiga to _______.

lianna [129]

The answer is a. evade predators.

Animals that live in taiga had to adapt to seasonal changes, by changing their fur or feather color. For example, snow-show hare and ermine live in taiga and their fur color changes with environmental conditions. To effectively camouflage, their fur is white during the winter. That helps them blend into the snow. In the summer, where there is no snow, their fur is brown and similar to the soil color. This way it is more difficult for their predators to spot them.
