Is biotic?
Does that help? What are the answer choices?
Answer:
The chloroplast is involved in both stages of photosynthesis.
Explanation:
The light reactions take place in the thylakoid. The dark reactions then occur outside the thylakoid. In these reactions, the energy from ATP and NADPH is used to fix carbon dioxide (CO2).
Answer:
Classification
Explanation:
Classification is the grouping of living organisms based on their structural similarities. Those with similar structures are put under one group referred to as a taxon. The grouping also takes into account the evolutionary relationships since all living organisms at one time had a common origin.
B. Kingdom
Kingdom is the largest Taxon in the Taxonomic Hierarchy
Answer:
I. The nuclear membrane breaks up.
II. Sister chromatids condense.
III. Sister chromatids align on the metaphase plate.
IV. The cleavage furrow forms.
V. Sister chromatids separate.
Explanation:
Mitosis is divided into 5 stages:
- Prophase
- Metaphase
- Anaphase
- Telophase
- Cytokinesis
The prophase stage is marked by two main events
- <em>Dissolution or breakage of nuclear membrane</em>
- <em>Condensation of genetic materials</em>
Metaphase is marked by
- <em>Alignment of chromosomes (made up of two sister chromatids) on the metaphase plate</em>
- <em>Attachment of spindles to aligned chromosomes at the centromere</em>
Anaphase is marked by
- <em>Initiation of cleavage furrow formation</em>
- <em>Shortening of spindle fibers results in the separation of sister chromatids</em>
- <em>Sister chromatids begin migrating to opposite poles</em>
Telophase
- <em>Chromatids completes their migration to the poles</em>
Cytokinesis
- <em>Nuclear membrane reforms</em>
- <em>Sister chromatids decondense</em>
- <em>Cytoplasm divides</em>
