Answer:
What's the question here?
Explanation:
Explanation:
The phase of Prophase I of meiosis is very long and divided into 5 subphases: Leptotene, Zygote, Pachytene, Diplotene, and Diakinesis. During a phase of the Diplotene, the degree of condensation is high, which allows individualizing the sister- chromatids that remain attached by the cohesins. The synaptonemal complex disintegrates, and from the centromeres begins a repulsion between homologous chromosomes, which remain associated only with the places where they occur as permutations.
These sites are called chiasmas (Greek, crossed) because they show the crossover of homologous chromatids. Chiasmas represent the cytological finding of the occurrence of permutation. The presence of at least one bivalent chiasm is essential to ensure the correct segregation of the homologous chromosomes in anaphase I.
Answer:
i think its the first one because i found this information that makes sence
Explanation:
Restriction enzymes are used in biotechnology to cut DNA into smaller strands in order to study fragment length differences among individuals. This is referred to as restriction fragment length polymorphism (RFLP). They're also used for gene cloning.
Given the fact that plants went extinct i would say overpopulation of the rabits did that cus if there are less rabits then there are more plants.
<span>A cell can only grow so large in size, because its surface area to volume ratio decreases as the cell becomes larger. The correct option is A. When a cell is growing, its volume increases at a greater rate than its surface area, therefore its surface area to volume ratio decreases.</span>
