In a classic experiment using pea shape, mendel conducted two separate genetic crosses. in the first cross the parent plants
were true breeding" for pea shape; one had round peas ( r )and the other had wrinkled (1). the first cross produced a filial 1
generation of all round peas. in the second cross, mendel bred plants from the filial 1 generation. this cross produced different
results. out of approximately 1000 plants, about 75% were round and 25% were wrinkled.
from these experiments, mendel developed four hypotheses. they include all but
one heritable factor may be dominant and mask the other factor
any organism that shows a heritable factor must be homozygous.
an organism has two "heritable factors", now called genes, one from each
parent
perm or egg carries only one heritable factor for each trait in the
offspring

answer: the exterior temperature of commercial jet planes as they leave the stratosphere and return to the ground increases steadily.

explanation:

the lower most layer of atmosphere is troposphere which extends from 0 to 12 km above the surface of the earth. the temperature initially decreases as distance is increased from the earth's surface. commercial jets fly in lower part of the stratosphere. the stratosphere extends upto 50 km. the temperature in stratosphere starts rising again due to presence of ozone which traps the uv rays.

thus, when the planes leave the stratosphere and return to the ground, the exterior temperature increases steadily.

the box does not move because you need to use a force greater than 300 n. you are only using 50 n. it needs to at least be 301 n for the box to move because then it is an unbalanced force and it will move the way that the greater force is pushing it. if you use only 300 n it will be a balanced force and will not move because the force you are exerting on the   box is the same as its force.

hope this !

im sorry if i went too in depth, i am going to include a link to a video on khan academy that will explain this.   hope that you like the video and that it explains more in detail to you.

that is the link.
