Answer:
The two chromosomes in a homologous pair are very similar to one another and have the same size and shape. Most importantly, they carry the same type of genetic information: that is, they have the same genes in the same locations. However, they don't necessarily have the same versions of genes.
Explanation:
Hope this helped, can i get a brainlest please? :)
Answer: Option A, B and D are correct.
Explanation:
ATP or adenosine triphosphate can be defined as the high energy molecules that is used by all the living organism.
This molecule is released by the combustion of carbohydrates in the presence of oxygen.
The energy is stored in the phosphate bonds and adenosine triphosphate contains 3 phosphate molecules.
The answer is <span>d. homologous structures.
Homologous structures are </span><span>similar structures shared by different species. For example, the anatomy of joints in bones of birds and dinosaurs, support the idea that these two groups have a common ancestor. But since these two groups are different enough to be separated into different classes, it can be concluded that they evolved from the common ancestor.</span>
Prokaryotes and eukaryotes both have a plasma membrane, mitochondria, golgi apparatus, and endoplasmic reticulum in common. But, prokaryotes have cell walls, chloroplast, and larger vacuoles because they are plant cells and animals don't need chloroplast since they don't undergo photosynthesis and don't need to hold as much water in their vacuoles.
A constitutive gene is unregulated, which means that its expression level is relatively constant. The expression of a
regulated gene varies under different conditions. In bacteria, the regulation of genes oftentimes occurs at the level
of transcription by combinations of regulatory proteins and small effector molecules. In addition, gene expression
can be regulated at the level of translation or the function of a protein can be regulated after translation is
completed.
<span>An inducible gene is a gene whose expression is either responsive to environmental change or dependent on the position in the cell cycle.</span><span>The rapid activation of gene expression in response to stimuli occurs largely through the regulation of RNA polymerase II-dependent transcription</span>
