Answer:
Options (C) and (D)
Explanation:
The oceanic crust is usually about 5-10 km thick and is comprised of rocks that are basaltic in nature. These rocks are primarily made of minerals such as iron (Mg) and magnesium (Mg) and a comparatively lesser amount of silicate materials. Much of the oceanic rocks are destroyed due to the constant plate tectonic movement. It has been found that the oldest oceanic rocks found on the earth's crust is about 180 million years old only. The new oceanic crust often forms along the mid-oceanic ridge in a divergent type of plate motion, where new materials are added to the crust. Those rocks that are present along the mid-oceanic ridge are the younger rocks and those that are away are the oldest rocks. These oceanic crust are comprised of the volcanoes that form adjacent to the convergent plate boundary.
Thus, the correct answer is options (C) and (D). Brainelst please

Answer:
LLgg, Llgg , two out of 16
Explanation:
Given,
Dominant - Long wings and Gray color
Recessive - Short wings and Brown color
Let the allele for long wings be "L" and the allele for short wings be "l".
Let the allele for brown color be "g" and allele for gray color be "G"
Genotype of parents
LlGg
Gametes of the parent
LG, Lg, lG, lg
Dihybrid cross is between LlGg and LlGg
The offspring produces will be as follows -
LG Lg lG lg
LG LLGG LLGg LlGG LlGg
Lg LLGg LLgg LlGg Llgg
lG LlGG LlGg llGG llGg
lg LlGg Llgg llGg llgg
Offspring with long wings and brown color – LLgg, Llgg , two out of 16
Answer: I think one observable adaptation of the redbud tree that makes it a member of the legume family is the shape of the fruit.
Explanation: Different species might look dissimilar but the unity among organisms becomes apparent from an analysis of internal structures, the similarity of their chemical processes, and the evidence of common ancestry
