The autonomic nervous system is divided into the sympathetic and parasympathetic subdivisions.
<span>In liver, the most intensively studied transmembrane and intracellular signal transduction pathways are the Janus kinase signal transduction pathway, the mitogen-activated protein kinases signal transduction pathway, the transforming growth factor β signal transduction pathway, the tumor necrosis factor α signal transduction pathway and the recently discovered sphingolipid signal transduction pathway. All of them are activated by many different cytokines and growth factors. They regulate specific cell mechanisms such as hepatocytes proliferation, growth, differentiation, adhesion, apoptosis, and synthesis and degradation of the extracellular matrix. The replication cycle of hepatitis C virus (HCV) is intracellular and requires signal </span>
Answer:
Plants have two distinct stages in their lifecycle: the gametophyte stage and the sporophyte stage. After reaching maturity, the diploid sporophyte produces spores by meiosis, which in turn divide by mitosis to produce the haploid gametophyte. The new gametophyte produces gametes, and the cycle continues.
Explanation:
Jan Ingenhousz discovered photosynthesis
With the sequence of the gene-coding regions of the human genome in hand and the development of newer sequencing methods, scientists are able to
1. develop new forensic tests that can help in the identification of the convict.
2. diagnose genetic diseases before their onset.
3. develop customised medicines based on the genetic profile of the patient.
4. therapeutically target the cancer causing genes (oncogenes) in the patients.
5. understand the inheritance of genes especially the rare mutations in a population.
