Answer:
Algae and fungi are biotic: temperature and rainfall are abiotic
Explanation:
Abiotic factors include non-living environmental factors like wind, temperature and light, and chemical elements. These affect the biotic, living factors and shape their survival. For example high temperatures hinder the survival of organisms, and a lack of rainfall creates drought conditions where biotic factors die off due to food scarcity.
Biotic factors comprise the most important environmental components; bacteria, plants, animals, and fungi. The interaction between these living organisms can be classed into three groups; producers, like algae, plants, trees and grasses; consumers, which are plants that eat other animals or producers; and decomposers, that break down dead organic matter into soil.
Answer:
Third farthest
Explanation:
mercury and venus are both closer to the sun than earth is, and all other planets are farther than earth.
Discharge (Because it is influenced by velocity not the other way around)
Because there is no indication of what's the highlighted structure I'm going to tell you where all the four muscles of the quadriceps femoris originate from.
The vastus lateralis originates on the greater trochanter and the lateral lip of linea aspera. The vastus intermedius originates on the lateral and anterior surfaces of the femur's body. The vastus medialis originates on the medial lip of the linea aspera and the intertrochanteric line. R<span>ectus femoris originates, </span>superior to the acetabulum, on <span>the ilium.</span>
Answer:
polar microtubules contract, pulling attached chromosomes toward the poles.
Explanation:
Polar microtubules are one of the two types of microtubules that together make the mitotic spindle. The polar microtubules are the ones that extend from each pole to the cell's equator.
At the equatorial region, the polar microtubules from two poles overlap. Also known as non-kinetochore microtubules, the polar microtubules do not get attached to the kinetochores of chromosomes.
The function of the polar microtubules is to assist in chromosome separation during anaphase. The polar microtubules from two poles slide past each other. As they slide, the degree of overlap is reduced and the two opposite poles are pushed apart.
The reduced overlap between the polar microtubules indirectly moves the chromosomes apart as the kinetochore microtubules attach the chromosomes to the opposite poles.
