Explain how tillage has negative effects on the environment.

Sergeeva-Olga [200]

Answer:

Soil Erosion

Explanation:

Basically, tillage breaks soil up, destroying its overall structure. It encourages surface runoff and therefore soil erodes more easily. In some cases soil erosion is beneficial, but in most cases, it is not. Tillage has also been found to cause the emissions of more toxic gases such as N20.

Which population is limited by density-dependent factors?

dedylja [7]

Answer: (c) A local wolf population experiences a lethal epidemic of parvovirus.

Explanation:

A limiting factor is one which is capable of limiting the population of the species. It can be a living factor or a non-living factor.

The density dependent limiting factor is a factor which affects the population of a species depending upon the size of the population. There are many density dependent limiting factors such as disease, migration, predation and food.

C is the correct option, this is because of the fact that the epidemic outbreak can spread over to the large number of members of the population. If larger the population size more likely will be the chances of spreading.

Lady bird [3.3K]

Answer:

Aldehyde has C=O bonded to atleast one H atom while Ketone has C=O bonded to two carbon atoms

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses

Explanation:

Similarity

Both the aldehyde and ketone have C=O group

Difference

In aldehye the C=O group require atleast one hydrogen atom or the functional group in aldehyde is -CHO

while in ketone the function group is C=O only that is bonded to two carbon atoms.

Example

Aldehyde - galactose, glucose, glyceraldehyde, fructose

Ketone - Trioses, Tetroses, Pentoses, Hexoses
