Retina allows the eye to regulate how much lint can enter.
Answer: Question 1 answer: Skin cells continually replicate
Explanation: The cells in the superficial or upper layers of skin, known as the epidermis, are constantly replacing themselves. This process of renewal is basically exfoliation (shedding) of the epidermis. But the deeper layers of skin, called the dermis, do not go through this cellular turnover and so do not replace themselves.
Question 2 answer: Heart cells undergo terminal differentiation
Explanation: Different cell types (e.g., neurons, skeletal and heart myocytes, adipocytes, keratinocytes) undergo terminal differentiation, in which acquisition of specialized functions entails definitive withdrawal from the cell cycle.
Question 3 answer: DNA replicates in the nucleus
Explanation: DNA replication occurs in the cytoplasm of prokaryotes and in the nucleus of eukaryotes. Regardless of where DNA replication occurs, the basic process is the same. The structure of DNA lends itself easily to DNA replication.
Question 4 answer: The ability to reverse terminal differentiation might affect gene expression in a complex organism
Question 5 answer Cytoplasm replicates during mitosis
Explanation: This process involves replication of the cell's chromosomes, segregation of the copied DNA, and splitting of the parent cell's cytoplasm. ... The outcome of binary fission is two new cells that are identical to the original cell.
Answer:
1. Make sure there are lots of bike paths
2. Design roads that work well with the area's public transportation
3. Include an HOV lane in the design
Explanation:
Green transportation planning is a form of planning in which roads are designed such that individuals are discouraged to drive alone on the road and at the same time utilized more environmentally friendly means of transportation. It also includes designing adequate lanes or paths for specific kinds of traffic or transportation.
Hence, in this case, the correct answers are:
1. Make sure there are lots of bike paths
2. Design roads that work well with the area's public transportation
3. Include an HOV lane in the design
