Answer:
D) homologous pairs of chromosomes form tetrads
Explanation:
During prophase I, the homologous chromosomes condense and become visible as the x shape we know, pair up to form a tetrad, and exchange genetic material by crossing over.
The answer is; D
The porous rock is able to absorb water from precipitation. The water resides in the pores of the rock. The impermeable rock later, which does not allow water to pass through it, allows more water to hold in the porous rock and making the local water table to rise. The water in the porous rock, therefore, can be accessed through wells or a water spring can develop.
<span><span>There are choices for this question namely:
A. Its photons have the shortest wavelength in the visual spectrum
B. Its photons have the highest energy in the visual spectrum
C. Its photons have the longest wavelength in the visual spectrum
D. It is not considered a part of the visual spectrum
The correct answer is that </span>its photons have the longest wavelength in the visual spectrum<span>. Chlorophyll, being green in color (around 495 to 590 nm wavelength), reflects this wavelength; not absorbed. Mostly, the chlorophyll absorbs longer wavelengths of light such as red (around 680 nm wavelength) and blue to violet (around 400 to 480 nm wavelnegth). </span></span>
