Answer:
The African savanna ecosystem is a tropical grassland with warm temperatures year-round and with its highest seasonal rainfall in the summer. The savanna is characterized by grasses and small or dispersed trees that do not form a closed canopy, allowing sunlight to reach the ground. The African savanna contains a diverse community of organisms that interact to form a complex food web.
Answer:
Option D
Explanation:
Cyanobacteria preserve its photosynthetic pigments in the thylakoids which allows masking of green of chlorophyll a and other accessory pigment i.e phycobiliproteins (phycocyanin, allophycocyanin and phycoerythrin).
Chlorophyll a is mainly responsible for harvesting light for photosynthesis. Phycocyanin is blue in color, allophycocyanin is blue in color and phycoerythrine is red in color. These together harvest light in the green, yellow and orange part of the spectrum which cannot be used by other phytoplankton species
Hence, option D is correct
Answer:
Well you have to tell the child that genetics is the study of how traits(characters) are passed on from parent to offspring. Such traits include height, weight, facial features etc.
Chromosomes are the cells that carry those traits in the body. Human beings usually have 46 chromosomes but during reproduction, the chromosomes are halved to give 23 which is in its haploid state so that each parent gives 23 chromosomes each to get 46 chromosomes which is the standard number of chromosomes for humans and animals.
Haploid means a single set of these chromosomes donated by the parent during reproduction while the 46 chromosomes which is achieved after reproduction is referred to as Diploid which means 2 set of the chromosomes from both parents.
