Answer:

You drove through Iowa in the spring and noticed that along a stretch of several kilometers, every third fence post had a male red-winged blackbird perched on it defending its nesting territory. This is an example of <u>uniform dispersion.</u>

Explanation:

There are usually three dispersion patterns :

Clumping
Uniform dispersion
Random dispersion

Clumping is the most common.

Uniform dispersion occurs when

resources are scarce
Individuals are evenly spaced in a habitat
Due to competition or territorial behavior

While Random dispersion occurs when resources are plentiful.

The pictures show close-up views of a fir tree and a cactus.

Akimi4 [234]

The fir tree can be found in the coniferous forest biome, and the cactus can be found in the desert biome.

Option C.

<h3><u>Explanation:</u></h3>

Both the cactus and fir trees are having modified tree leaves due to the same purpose - saving water.

The fir trees are found in the coniferous forests which are mainly seen in mountains or in the temperate region. Both the regions face very cold climates and frequent snowfalls in every years. This is why there's a lack of water in the surroundings. This is why they need to save water and minimize transpiration.

Whereas the cacti are found in desert or semi arid regions where water is itself very scarce and temperature is either very high or very low. So they have their leaves converted into spines which help to reduce transpiration.

Answer:

27:9:9:9:3:3:3:1

Explanation:

The gametes of the parental genotypes would be

ABC, ABc, AbC, aBC, Abc, aBc, abC, abc

The cross between AaBbCc and AaBbCc will result into following offspring (image is also attached)

ABC ABc AbC aBC Abc aBc abC abc

ABC AABBCC AABBCc AABbCC AaBBCC AABbCc AaBBCc AaBbCC AaBbCc

ABc AABBCc AABBcc AABbCc AaBBCc AaBbcc AaBBcc AaBbCc AaBbcc

AbC AABbCC AABbCc AAbbCC AaBbCC AAbbCc AaBbCc AabbCC AabbCc

aBC AaBBCC AaBBCc AaBbCC aaBBCC AaBbCc aaBBCc aaBbCC aaBbCc
