Answer:
pollen is important in fertilization because pollen carries male gamete and it helps in transportation of male gamete during fertilization in mainly gymnosperms and angiosperms.
The Lithosphere contains all of the cold, hard, solid rock of the planet's crust, the hot semi-solid rock below the crust, the hot liquid rock near the center of the planet, and the solid iron core. The biosphere is the sphere that contains all of the Earth's living organisms. The organisms and crust interact through events between spheres, such as natural events like floods, shifts in the Earth's crust. Some event as such could create soil erosion resulting in decreased vegetation and increase death of organisms. <span>

Answer:
Brown is the dominant gene and white is the recessive gene.
Explanation:
If brown were to be dominant then the mice would most likely all be brown unless the got both a white from mom and dad which is most likely due to brown being recessive the dad could be part white you just wouldn't see it. And since the mother is white all of the mice get a white gene from the mom and since the dad most likely has a white gene hidden inside of him only tow mice became fully white while the siblings were brown.
Hope this helps.
<span>If each of the pairs of
chromosomes was heterozygous (what gives you the highest potential
number of different gametes), then the number of possible gametes
increases from 4 to 8 for a diploid organism. To figure out how many
are possible, raise the number of homologous chromsomes (2 for a diploid
organism) to the power of the number of chromosomes. So if you have
two different chromosomes (A and B), raise 2 to the 2nd power (or
multiply 2 x 2) and you have 4. If you have chromosomes A, B, and C,
then you have 2^3, or 2 x 2 x 2 = 8.
To show possible combinations, AaBb gives you AB, Ab, aB, or ab. AaBbCc
gives possible gametes of ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc. </span>
Answer:
The given image shows - the Stomata that helps in maintaining homeostasis in the plants.
Explanation:
Stomata are the small structure resemble as tiny or pinholes that found on the underside of the leaves and play many roles in the plant. Stomata help in the gas exchange and also helps in transpiration. It allows oxygen a gas and water in vapor form from the leaves to the outer environment and let carbon dioxide inside the cell.
This system also helps in transpiration by closing and opening stomata with the help of their guard cell by becoming turgid and flaccid by osmotic pressure.
