Analogous structures have a different evolutionary ancestries but they have the same function
while homologous structures are the opposite; they have similar ancestries and common traits but maybe not have the same function in an organism
Explanation:
The opening and closing of stomata are controlled by the guard cells. When water flows into the guard cells, they swell up and the curved surface causes the stomata to open. When the guard cells lose water, they shrink and become flaccid and straight thus closing the stomata
Guard cells regulate the passage of water vapor, oxygen, and carbon dioxide into and out of the leaf. When the guard cells are very turgid, they pull apart, opening the stoma. When the guard cells lose water and become flaccid, they collapse, closing the stoma.
Answer:
D. Mendel's law of independent assortment is being violated.
Explanation:
For independently assorting genes, a dihybrid test cross gives progeny in 1:1:1:1 ratio. Here, a dihybrid (BbGg) is crossed with a double homozygous recessive individual (bbgg). If the genes were assorted independently, four types of progeny would have been produced in 1:1:1:1 ratio.
However, the progeny has more proportion of offspring with black eyes, green skin, and orange eyes, white skin. This means that the genes for orange eyes and white skin are linked. Likewise, the genes for black eyes and green skin are linked. Linked genes do not assort independently and are one of the exceptions for Mendel's law of independent assortment.
Yes this is right. You post questions on here just like you do now and then people will come and answer it in this box here.
