1. “Some resources have economic value, some do not”. Give a example. 2. Human being are an important resource. Justify this statement.

3. Why do you think the use of resources should be sustainable? Explain.

4. Make a list of things that you see in your home and at school. Classify them into natural and

human-made resources. Then sub-classify the natural resources on the basis of their origin,

development, renewability and distribution. Also, trace the natural source from which the
human-made things are made.

5. Design a poster for the school display board to spread awareness on the need to conserve our natural resources.​

The dna in a cell’s nucleus encodes proteins that are eventually targeted to every membrane and compartment in the cell, as well as proteins that are targeted for secretion from the cell. for example, consider these two proteins: phosphofructokinase (pfk) is an enzyme that functions in the cytoplasm during glycolysis. insulin, a protein that regulates blood sugar levels, is secreted from specialized pancreatic cells. assume that you can track the cellular locations of these two proteins from the time that translation is complete until the proteins reach their final destinations.for each protein, identify its targeting pathway: the sequence of cellular locations in which the protein is found from when translation is complete until it reaches its final (functional) destination. (note that if an organelle is listed in a pathway, the location implied is inside the organelle, not in the membrane that surrounds the organelle.)

Compare and contrast region e in the illustration above with region d. describe the physical characteristics of each region.

Suppose you have monohybrid pea plants in your garden and find that they produce round seed to wrinkled seeds in the ratio of 3: 1. if the allele are designated (r & r) receptively. what is the probable genotypes of the round seeds which produced f 1 ? rr & rr rr only rr & rr rr only rr only
