Answer:
Replicated chromosomes at metaphase I = 66
Sister chromatids at metaphase I = 66 x 2 = 132
Sister chromatids at prophase II = 66
Chromosomes in each sperm cells = 33
Explanation:
Metaphase I of meiosis I would have 66 replicated chromosomes in the testicular cells of the bird. Each of the replicated chromosomes would have two sister chromatids. So, a total of 66 replicated chromosomes would have 66 x 2 = 132 sister chromatids.
Due to segregation of homologous chromosomes towards opposite poles in anaphase I, each daughter cell formed by the end of meiosis I would have 33 replicated chromosomes. So, each of the daughter cells would have a total 33 x 2 = 66 sister chromatids at prophase II.
Since meiosis II maintains the chromosome number, each sperm cell formed by the end of meiosis II would have 33 chromosomes.
Answer:
- Both processes form minerals.
- Volcanic eruptions form precipitates and shifting of tectonic plates form minerals.
Explanation:
Both volcanic eruptions and the shifting of tectonic plates form minerals. Volcanoes and their eruptions can directly or indirectly lead to the formation and/or deposit of minerals such as diamonds and zinc. Shifting also forms minerals due to the forces of compression the plates apply on each other as they move past.
Volcanoes are known the cause precipitates because when the erupt, the ash that is released mixes with water vapor which then becomes rain eventually.
The limitations in designing and building an eco-friendly home in Illinois will be climate constraints and social limitations.
<h3>What are eco-friendly homes?</h3>
Eco-friendly homes are homes which are designed such that they do not pose any danger to the envrionment.
Eco-friendly homes are compatible with the environment and make use of available environmental resources to design an environmental-friendly home.
The limitations in designing an eco-friendly home in Illinois will be:
- Climate constraints - due to hot climatic conditions
- Social constraints - due to its dense population
Therefore, the limitations in designing an eco-friendly home in Illinois will be climate constraints and social limitations.

Answer:
In trees, most savanna adaptations are to drought--long tap roots to reach the deep water table, thick bark for resistance to annual fires (thus palms are prominent in many areas), deciduousness to avoid moisture loss during the dry season, and use of the trunk as a water-storage organ (as in baobab).
The answer is B) Amoeba
