Anthropods have exoskeletons
DNA is unzipped by helicase at the origin of replication. There are several origins of replications in eukaryotic DNA replication, while only one in prokaryotic replication.
Answer:
economic and everything
Explanation:
If one population dies out, all the populations that depend on that species for food may also die out. A change in one population affects the entire community because all the populations of a community depend on each other. ... A population is all the members of one type of organism living in an ecosystem.
As a population grows in an area, a population may experience the effects of increased densities. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).
Chemically straightening hair changes the shape of disulfide bonds, which alpha keratin protein; this is the second protein structure. However, as the hair continues to grow out, this keratin protein grows with it, thus outlasting the effects of the chemicals which change the shape of the protein.
Stem cells arise from the inner mass of the cell
Signalling factors trigger differentiation in stem cells
Genes that lead to the production of undifferentiated blood cells are activated
Signalling factors cause undifferentiated blood cells to produce red blood cells
Explanation:
Red blood cells are formed in the bone marrow. The precursor to the RBC is stem cell which is undifferentiated and pluripotent. The stem cell gets differentiated to form immature RBCs. Immature RBC then gets divided and becomes mature. Stem cell giving rise to RBC is called Haemoctytoblast. The process of erythropoiesis takes 2 days to form new red blood cells
