What valuable information was gained from Mendel's dihybrid crosses?
Select all that apply.
1. Not all traits are controlled by genes. In most plants, genes only determine traits that affect
flower color.
2. Statistical and probability methods can be used to determine how likely an offspring is to inherit
certain traits.
3. Genes are inherited differently in plants than they are in animals.
4. Inheritance of one trait does not affect inheritance of another.
Answers
Mendel's dihybrid cross proves that the inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.
What is a dihybrid cross?When two different traits are crossed together then it is called a dihybrid cross. These two different traits are regulated by two different genes.
In Mendel's dihybrid cross, he did cross between round yellow and wrinkled grees. There are two traits, color, and shape. In the F1 generation, all seeds were round yellow but they were heterozygous. Round shape and yellow color are dominant traits.
Then he self-pollinated F2 generation and found four types of seeds that were round yellow, round green, wrinkled yellow, and wrinkled green in the 9:3:3:1 ratio. The cross is attached in the image below.
Inheritance of one trait does not affect the inheritance of another trait. Hence, option 4 is correct.

Answer:
Plant cell
Explanation:
Cell wall: cell wall is only found in plant cell . it is made up of cellulose. it's function is to give shape to the cell and protect the delicate inner parts of the cell. this cell is fully permeable. it means it will allow all substance to pass in. cell membrane is made up of protein and lipids. it's function is to control what comes in and out of the cell. this membrane is selectively permeable. it means it allows some substance to pass in and others don't. cytoplasm is large sac like structure. most chemical process occur here. chromoplast are the green pigments.
cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .

Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Which phase of the cell cycle is helicase most likely active?
A) S
B) М
C) G1
D) G
Answers
Helicase is an enzyme responsible for unwinding the double helix of the DNA by breaking apart the hydrogen bonds between each of the base pairs. Helicase is more active in the S phase of the cycle. Option A is the correct answer.
What are the events of the cell cycle?
The cell cycle consists of the interphase and the cell division phase, where the cell division takes a little time in comparison to the interphase. The parent cell spends the majority of its time in the cell cycle's interphase and less time in the cell division phase.
There are three phases in the cell cycle's interphase: G1, S, and G2. The cell grows in both the G1 and G2 phases, while the DNA replicates in the S phase.
Hence, helicase is an enzyme that is responsible for unraveling the double helix of DNA by breaking apart the hydrogen bonds between each base pair. Helicase is more active in the S phase of the cell cycle. Option A is the correct answer.

Women gives birth to a baby boy. A few years later she gives birth to another baby boy. What is the probability that her third child will be a girl? Play your reasoning
Answers
Answer:
50 %
Explanation:
It is given that a woman gives birth to a baby boy. Her second child is also a baby boy. Now she is about to give birth to her third child. We have to determine the probability of the child to be a girl.
Here, the probability of the child to be a girl would be 50 % or 1 out of 2.
There are two possibilities and the possibilities would result a boy child or a girl child. So there are two possible outcomes and is equally likely with each child birth.
Also each child birth is an independent event, so the probability that the one results will occur do not depend on the previous births.
Use signal words from the passage to determine

This water usually flows into rivers or streams. Precipitation can occur as rainfall, snow, hail or sleet and falls from clouds when condensation occurs. Transportation is the process by which trees release water vapor into the atmosphere via stomata in the leaves.
