Answer:
The three processes from left to right are:
<u>Replication</u> DNA <u>Trancription</u> RNA <u>Translation</u> Protein
Explanation:
The process in question in the diagram is called the central dogma of life which describes the flow of genetic information from DNA to RNA to Protein. The three processes involved are:
- DNA Replication
- Transcription
- Translation
DNA Replication:
DNA replication is the process by which DNA makes a copy of itself. Replication of DNA is semi-conservative. this means that each new helix is a combination of an old (parent) strands and a new (daughter strand). The parental strand is used as a template to generate a complementary daughter strand.
Transcription:
Transcription is the formation of an RNA transcript of the DNA template. This process yields a mRNA that is further used as a code to manufacture proteins in the process of translation.
Translation:
Translation decodes the mRNA formed in transcription to generate proteins with specific amino acid sequence.
Plant cell needs cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out . All cells have cell membranes, and the membranes are flexible. So animal cells can have various shapes, but plant cells only have the shapes of their cell walls.
Answer:
a) Myelinated nerve fibres
b) The white matter
c) gray matter
Explanation:
The three main parts of cerebral hemispheres are
a) Myelinated nerve fibers
b) The white matter
c) Gray matter
The nerve fibers of the white matter are responsible for connecting the functional parts of cerebral cortex while the gray matter is further divided into four surface folds/lobes with each lobe associated with a specific activity. Such as frontal lobe take cares of motor activity and speech, parietal lobe is responsible for touch and position sensation, occipital lobe for vision and temporal lobe for hearing.
Sponges are organisms that are members of phylum prolifera, they are simple multicellular animals without a mouth, muscles, heart or brain.Sponges's tissues contains collar cells and amoebaocytes in its tissues. They feed by drawing water in through their pores and filter out food particles. Sponge larvae are more animal-like than adult sponges because they are free-swimming organisms.
