how has the change in land use affected the balance of photosynthesis and respiration? how could we change land use to stabilize or reverse this trend?
If there is a change in land use, it will cause the plant to decrease so that the reduction in carbon storage is also reduced, so it becomes a contributor to global climate change. To stabilize this situation, we can use land with go-green innovations.
The by-product of respiration is CO₂ which will be released into the atmosphere. The process of photosynthesis in plants requires CO₂ from respiration. When there is a change in land use, it will cause a decrease in vegetation so the reduction in carbon storage is also reduced. So, the atmospheric concentration of CO₂ (carbon dioxide) from respiration will increase thereby contributing to global climate change.

What is the regulatory gene cascade triggered by bicoid that leads to the differentiation of segments along the anterior-posterior axis of the fly embryo?.
The bicoid starts a regulatory gene cascade that leads to segment differentiation along the fly embryo’s anterior-posterior axis.Hox, segmentation, and effector genes are among these genes.
There are numerous genes that encode transcription factors, and these transcription factors in turn cause the production of more transcription factors, causing cascades of gene expression that amplify the initial signal via various signalling pathways.In fruit flies, approximately 25 genes control the differentiation of the embryo into discrete segments, resulting in changes in the number and organisation of the segments. Mutations in these genes frequently result in the disruption of entire groups of segments.Hox genes, a family of homeotic transcription factors, play a crucial role in controlling the body design along the craniocaudal axis.The Bicoid and Nanos gene products can be used to identify the anterior-posterior axis in Drosophila. Nurse cells are responsible for transcription of the bicoid gene’s mRNA. The unfertilized egg contains the bicoid mRNA close to its anterior pole. As a result, the anterior morphogen is the bicoid gene product. After fertilisation, the bicoid mRNA begins to be translated.
