Answer:
plant organisms can alternate between diploid sporophyte and haploid gametophyte phases.
Explanation:
Once mature, the gametophyte produces male and female gametes. When haploid gametes unite, they form a diploid zygote. The zygote grows via mitosis to form a new diploid sporophyte,Thus unlike in animals.
Answer
During transcription, the enzyme RNA polymerase (green) uses DNA as a template to produce a pre-mRNA transcript (pink). The pre-mRNA is processed to form a mature mRNA molecule that can be translated to build the protein molecule (polypeptide) encoded by the original gene.

Answers
1. True, trees shed their leaves during winter to survive the harsh winter.
2. True, some trees have leaves that are pointed needles to survive the cold.
Explanation
Trees lose their leaves during winter , during this period, the ground freezes making the soil to be dry as in desert, hence to reduce loss of moisture through transpiration that occurs via the leaves, the trees shed all leaves until warmer springs start. For example deciduous trees in temperate forest shed leaves every winter.
Needle like leaves can survive ice and snow during cold. Insects will not be able to feed on such leaves because of their toughness. In addition to that, needle shaped leaves have lower wind resistance thus can not easily make a tree fall over during big storms.
Objects in a solid stay in a a fixed position and have no freedom to move.<span>The particles of the solid (the atoms or molecules) are attracted to each other. </span><span>The atoms vibrate and the electrons fly around in their orbitals, but the entire atom does not change its position. This is the reason why solids hold their shape and don't flow.</span>
Answer:
Option B) Serine-Phenylalanine-Aspartic acid
Explanation:
mRNA codons AGC code for the amino acid, serine while UUC code for phenylanine and GAU code for aspartic acid.
Thus, the resulting amino acid sequence after translation will be a tripeptide containing Serine-Phenylalanine-Aspartic acid
