Your body is kept warm in your home primarily by two ways: by direct contact with the air around you and by absorbing infrared light that is radiated from the walls. As you have seen in this activity, the light that is radiated from an object depends almost solely on the temperature of the object. Based on what you have learned here, what is one reason for feeling warmer in your house on a summer day versus a winter day even though your thermostat is set the same?a - The walls of the house are warmer during the summer. Therefore, they radiate more infrared light that can serve to warm our body.
b - The walls of the house are warmer during the summer. Therefore, they radiate more visible light that can serve to warm our body.
c - The walls of the house are warmer during the summer. Therefore, they radiate more ultraviolet (UV) light that can serve to warm our body.
d - The temperature of the walls of the house has no effect on the light they radiate.

In the nineteenth century, gregor mendel first determined some basic rules of genetics that have been observed throughout all types of life. no observations have disproved these basic rules of genetics. charles darwin developed the idea of biological evolution around the same time, but he was unaware of mendelâs discoveries in genetics. over a century later, darwinâs idea of evolution was modified in order to incorporate mendelâs rules of genetics along with the other evidence that darwin had used. what is most likely the relationship between mendelâs rules of genetics and darwinâs idea of biological evolution? a.)mendelâs genetics states laws that are now part of the theory of biological evolution.b.)biological evolution states laws that are part of mendelâs theory of genetics.c.)mendelâs genetics replaced darwinâs entire concept of biological evolution.d.)biological evolution is a law that explains why all genetics exist.
