Answer:
La biomasa (energía) se refiere a la biomasa «útil» en términos energéticos formales: las plantas transforman la energía radiante del Sol en energía química a través de la fotosíntesis, y parte de esa energía química queda almacenada en forma de materia orgánica; la energía química de la biomasa puede recuperarse quemándola directamente o transformándola en combustible.
Explanation:
Warmer, colder
Convection is the transfer of heat by the movement of a fluid (liquid or gas) between areas of different temperature.
Warmer fluid is less dense so it rises and colder fluid is more dense so it sinks.
Answer:
begins even before the introduction of photography
Explanation:
cameras evolved from the camera obscura though many generations of photographic technology
Answer:
If there is homologous chromosomes (metaphase I) or duplicated chromosomes/sister chromatids (metaphase II) in the middle of the cell.
Explanation:
Meiosis involves two series of nuclear divisions grouped into meiosis I and meiosis II. Each division has the same number of stages i.e prophase, metaphase, anaphase, telophase etc. Meiosis I involves the separation of homologous chromosomes i.e similar but non-identical chromosomes from each parent.
On the other hand, meiosis II involves the separation of sister chromatids (duplicated chromosome). Since METAPHASE is generally characterized by the alignment of chromosome at the middle of the cell for separation in the anaphase stage, it means that the difference between metaphase in meiosis I and II will be whether it is homologous chromosomes that are in the middle or sister chromatids.
Therefore, according to this question, I would know if the cartoon is in metaphase I or II if:
- there are homologous chromosomes in the middle of the cell (metaphase I)
- there are sister chromatids in the middle of the cell (metaphase II).
Answer:
I believe "B"
Explanation:
In the Sun, the flows of hot plasma in the convection zone create the solar magnetic field. This is sustained by nuclear fusion in the Sun. ... The number of sunspots on the sun increase and decrease over time in a regular, approximately 11-year cycle, which is, in fact the solar magnetic activity cycle.
