True/False: The Northern Hemisphere experiences winter when Earth is farthest from the sun.

Answers

when the earth is farthest from the sun, then the either the west or east hemisphere experience winter. The earth revolves around the sun which is the center of the solar system.Hence the answer to this problem must have to be false. There is no difference between the north hemisphere and the south hemisphere in this case,

Answer;

True.

When the northern part of the earth is farthest away from the sun it gets cold and the other side of the earth gets warm / summer

Explanation;

The Earth's orbit is not a perfect circle, but a bit lop-sided. During part of the year, Earth is closer to the sun than at other times. However, in the Northern Hemisphere, we are having winter when Earth is closest to the sun and summer when it is farthest away.

When it is Summer in the Northern Hemisphere, it is Winter in the Southern Hemisphere, because the Earth is tilted on its axis.

Explanation:

A chicken feed claims to produce more eggs. an experiment is to be conducted to determine whether the feed will lead to a higher egg production. it was determined the type of chickens impact egg production, but the amount of water a chicken drinks does not. how would blocking best be used? (1 point) a by blocking on chicken egg production b by blocking on chicken feed c by blocking on chicken water intake d by blocking on chicken type

Answers

Blocking would be best used 'by blocking on chicken type'. This means conducting separate trials for different types of chickens while testing the chicken feed because the type of chicken was determined to impact egg production.

In a scientific experiment where the aim is to conclude whether a certain chicken feed leads to higher egg production, blocking would be used to control the variables that might affect the result of the experiment. According to the information given, chicken's water intake is said to have negligible influence on egg production, however, the type of chicken does impact the production quantities.

Therefore, the ideal way to apply blocking to the experiment would be by differentiating the groups of chickens based on their type; this method is referred to as blocking on chicken type. The implication of this is, testing different chicken feeds on different types of chickens separately to ensure the accuracy of the experiment results by eliminating confounding factors.
