The difference between plant and animals is that plants take carbon dioxide while animals breathe in that oxygen and breathe back out carbon dioxide
Answer:
A. Mendel observed green and yellow pea pods in a 3:1 ratio because the F1 generation was heterozygous.
Explanation:
The two true breeding plants in the parental population were homozygous (that is what true breeding means). Therefore, their cross would lead to all heterozygous offspring (see attached punnet square). Green is the dominant characteristic, so all F1 plants had a green phenotype, but Gg genotype.
The F1 cross would therefore be Gg x Gg. See attached punnet square.
The genotypes in the F2 generation are 1 GG: 2 Gg: 1 gg 1
Therefore, the phenotypic ratio is 3 green pea pods (Gg or GG): 1 yellow (gg)
Answer:
The correct answer will be- Meiosis I, anaphase I
Explanation:
Alleles are the variant alternative forms of a gene which determines the trait of an organism. The trait or phenotype is expressed only when the two alleles controlling a single trait on separate chromosomes are aligned in a complementary position.
During gamete formation, the alleles controlling a trait segregate independently of each other. This segregation of alleles takes place during Anaphase I of meiosis I. During anaphase, the sister chromatids are separated by the mitotic spindles so that the chromosomes can reach the opposite poles.
Thus, Meiosis I, anaphase I am the correct answer.
A,B,D are correct so C , is the one that will change the cell theory
Seismic waves travel in all the directions and used to determine the magnitude of an earthquake. There are 3 types of seismic waves that move in different directions.
1. P wave: It is the fastest of all three waves that travel through the interior of the earth and are compressive waves.
2. S wave: Secondary waves generally follow the P waves and travel through the interior of the earth but are shearing waves.
3. Surface wave: This is the slowest of all three waves that moves close to the surface of the ground.
These waves affect the movement of other materials when they are passing through the interior or surface of the earth.
P waves can move through the solid rocks and even liquids. S waves do not travel through the liquids such as water and molten magma. Surface waves causes shaking of the ground and do not go deep inside the earth.
