Hope this helps
D. Tides. Tides are full of water and thus less likely to always be changing from wind erosion.
Answer:
Option b.) propulsion: physical breakdown of ingested food in the GI tract
Explanation:
The physical breakdown of ingested food in the GI tract is called Mechanical digestion, and it breaks the food into smaller parts, to have more surface area for digestion, also to increase mobility. An example of Propulsion is the act of swallowing, which objective is to move the food through the digestive tract.
The correct order of functions is: Ingestion, Propulsion, Mechanical digestion, chemical digestion and Absorption.
Answer:
The estimated number of green seeds in the F2 generation is 2007, approximately.
Explanation:
<u>Available data:</u>
- Cross of a true-breeding plant that produced green seeds with a true-breeding plant that produced yellow seeds
- The entire F1 generation produced yellow seeds.
- Cross of the F1 offspring with each other to produce the F2 generation
- From the F2 generation, there were 6022 yellow seeds.
<u>1st Cross:</u>
Parental) YY x yy
gametes) Y Y y y
F1) 100% Yy
<u>2nd Cross</u>
Parental) Yy x Yy
Gametes) Y y Y y
Punnet square) Y y
Y YY Yy
y Yy yy
F2) 75% yellow, Y-
25% green, yy
What is a likely estimate of the number of green seeds he collected from the F2 generation?
From the whole F2 generation (100%), 75% are yellow seeds, which means that the remaining 25% are green seeds. According to this, 75% of the seeds, equal 6022 seeds. So we need to know how many seeds equal the 25% of green seeds. This is:
If 75% of the F2 generation ------- 6022 seeds
then 25% of the F2 generation -----X = 2007.333 seeds
<em>The estimated number of green seeds in the F2 generation is 2007, approximately. </em>
