A testable question is B. If a plant is turned upside down, which way will the roots grow?
The other options are incorrect because you cannot create some kind of experiment to prove them right or wrong.
Hope that helped you.
Plants use sugars and mineral from the sail to make food and use the energy from the sun to create the sugars used to make the food. They also use the carbon dioxide from the air to help create the food.
Answer:

Answer:
The direct conversion of mesenchymal tissue into bone is called i<u><em>ntramembranous ossification</em></u> .The process by which a cartilage intermediate is formed and replaced by bone cells is called <em>endochondral osssification.</em>
Explanation:
Intramembranous ossification is one of the two essential process during the fetal development of the gnathosome skeltal system by which rudimentary bone tissue is created. It is the process of bone development from fibrous membranes. It is involved in the formation of the flat bones of the skull, mandible and the clavicle. This type of ossification also helps in healing of bone fractures.
Endochondral Osssification: Method of forming a bone through cartilage intermediate. It is also involved in the formation of long bones.
Answer:
Four
Explanation:
Let the allele for black fur be B (the alternate will be b), the allele for active behavior be A (the alternate will be a), and the allele for light eyes be L (the alternate will be l).
<em>Heterozygous dominant for black fur = Bb</em>
<em>Heterozygous dominant for active behavior = Aa</em>
<em>Homozygous recessive for light eyes = ll</em>
Hence, the genotype for a male that is heterozygous for the dominant traits of black fur and active behavior but is homozygous recessive for light eyes will be BbAall.
Bb Aa ll
Possible Gametes
<em>BAl, Bal, bAl, and bal</em>
Therefore, the number of different types of gametes produced by the male mouse is four.
