Answer:
Letter A
Explanation:
From the description you make, it's likely that the structure with letter A is the chloroplast. It is round and small and it's free because of the pigment needed for photosynthesis (chlorophyll). It is located inside the cell, suspended in the cytoplasm.
As humans we can do whatever to gentically modify trees, but trees take over 100 years to grow back, to fix this, we could prevent unessecary tree cutting and plant new trees for the next generations , they're renewable because they can be replenished over a course of time
Answer:
B. transporting substances in a cell
Explanation:
Endomembrane system is basically a system or organelles and membranes in eukaryotic cells, which is involved in packaging, modifying and transporting the proteins and lipids across the cell.
Many organelles and membranes play role in this system like lysosomes, endoplasmic reticulum, Golgi bodies and nuclear membrane.
Note: Chloroplasts, Mitochondria and peroxisomes are not part of endomembrane system.
You can see figure depicting endomembrane system for better understanding.
Answer:
Genotype of the offspring: 4 CC is equal ratio. Phenotype will be 4 yellow cocoons. (CC)
Explanation:
The inheritance of cocoon color in silkworm is a classic illustration of mono-hybrid cross. Mono-hybrid because the color of cocoon is determined by single gene. The yellow color of cocoon is dominant and the homozygous dominant allele is represented as CC. While the white color of cocoon is represented as cc homozygous recessive alleles. As per punnett square method the offspring cocoon color will follow the above mentioned genotypic and phenotypic ratios respectively.
