Pls help me A population of ducks lives in an area that floods many times each year. Some of the ducks are better at finding food on dry land, while other ducks are better at finding food in wet, muddy areas. Eventually, the land around the lake permanently changes from dry soil to wet, marshy mud.

How will this change to the land most likely affect the duck population?

The population will remain stable because the ducks will not be affected by this kind of change.
The population will eventually balance out so that there are equal numbers of both types of ducks.
The population will evolve so that most ducks survive no matter how they find food.
The population will evolve so that most ducks are better at finding food in wet, muddy areas.

Study the image.

Point 1 is beneath water moving toward land. Point 2 is next to an erupting vocano. Point 3 is beneath Earth apostrophe s crust moving toward the water. Point 4 is the same layer as Point 1 moving down below Point 3.

At which point is subduction occurring?

1
2
3
4

The diagram shows a shell fossil.

Which type of fossil is shown?

mold
cast
trace
imprint

In which era did mammals emerge?

Cenozoic
Mesozoic
Paleozoic
Precambrian

The picture shows two different species of mammals that use wings to glide among tree tops. However, scientists theorize that these mammals are not closely related.

Which best explains why these two animals look so similar if they are not closely related?

They have analogous structures that developed for different functions.
They have homologous structures that developed for different functions.
They live in similar environments and have analogous structures adapted to them.
They live in similar environments and have homologous structures adapted to them.

thanks if you know these

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
