In the state of washington, the prevailing winds blow eastward off the ocean and up and over two mountain ranges. biologists are
stepan [7]
The fern should be found on the west side of the mountain ranges at higher elevations because the prevailing winds are from the west off the Pacific Ocean so bring moisture in the clouds and as the clouds rise up over the westernmost mountains they cool off and precipitate so in the warm seasons rain would be concentrated in this area and higher up would be cooler.

Which parasitic protist evades the host immune system by altering its surface proteins with each generation?
aleksandr82 [10.1K]

Answer:

Trypanosoma brucei

Explanation:

T. brucei is a unicellular eukaryotic parasite that causes sleeping sickness. This organism has an elongated body, central nucleus, only an elongated mitochondria housing the kinetoplast, where the mitochondrial DNA is located; It has a scourge that gives it motility. Its undulating cell membrane, as a result of flagellar movements, is covered with glycoproteins that elicit little immune reaction, allowing this parasite to go unnoticed.

This organism infects the host by evading the host's immune system by altering its surface proteins with each generation.

d1i1m1o1n [39]

Answer:

Brown eyes = 0.5

Blue eyes = 0.5

Explanation:

Given, B ( brown eyes ) is dominant over b ( blue/light eyes ). So,

BB = Brown

Bb = Brown

bb = blue/light

Mr. O'Ryan = blue eyes = bb

Mrs. O'Ryan = heterozygous brown eyes = Bb

Their children: Bb X bb :

      B        b

b    Bb     bb

b    Bb     bb

Half of the children will have Bb genotype and brown eyes, other half will have bb genotype and blue eyes. Hence, Kellan O'Ryan has 0.5 probability of blue eyes and 0.5 probability of brown eyes.
