Which statement accurately describes how genetic information is transferred during meiosis?
Meiosis creates four daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates two daughter cells that have half the number of chromosomes that are present in the parent cells.
Meiosis creates four daughter cells that have identical genetic information to the parent cells.
Meiosis creates two daughter cells that have identical genetic information to the parent cells.
Meiosis is the reductional division which creates four daughter cells that have identical genetic information to the parent cells. Thus, the correct option is C.
What is Meiosis?Meiosis is a special type of cell division which is also called as reductional division. This division takes place in the germ cells in sexually reproducing organisms which results into production of gametes, such as sperm or egg cells. Meiosis involves two rounds of division which ultimately result in the formation of four cells with only one copy of each chromosome or half genetic content.
Meiosis is divided into two divisions: Meiosis I and Meiosis II. In which, Meiosis II is similar to Mitosis and Meiosis I involves the reduction of genetic material to half.
Therefore, the correct option is C.

• What does the Human Genome Project decode?
• How is that code represented?
• What has the project revealed about the differences between humans and bananas?
• What questions does the Human Genome Project raise for you?
• What are outliers, and what is their value in understanding disease?
• How can a genetic mutation be advantageous?
• How is the knowledge of mutations being used to combat the HIV virus?
In this activity, students learn about the Human Genome Project. They do an interactive Web activity which simulates the process scientists use to determine the sequence of chromosomal DNA bases. Then they learn how two teams of scientists raced to decode the human genome. Next they explore a stretch of sequenced DNA on the Web to learn about the function of different sections of DNA code. They learn how knowledge of the human genome is being applied to medicine. They also learn about genetic variation among humans and between humans and other species. Finally, they assess what they have learned about the Human Genome Project by playing a game of Jeopardy.
Objectives
Learn about the purpose and work of the Human Genome Project
Describe the process of sequencing human DNA
Understand the functions of different stretches of code on a chromosome
Recognize the similarity in the genetic code among humans and between humans and other species
Learn how the Human Genome Project can contribute to curing diseases

Before the Lesson
Review the concepts of and relationships between DNA, genes, proteins, chromosomes, and traits.
After the Lesson
Do a wet lab in which students extract their own DNA from a cheek cell (see Extract Human DNA from Cheek Cells activity).
The Lesson
Part I
1. Show the Human Genome Project video. Discuss the following:
What does the Human Genome Project decode?
How is that code represented?
What has the project revealed about the differences between humans and bananas?
What questions does the Human Genome Project raise for you?
2. Now have students explore the DNA sequencing process by doing the Web activity Sequence for Yourself. Use the following questions to elicit student responses, either in writing or as part of a whole-class discussion:
Why does the DNA have to be cut into pieces? How is this done?
How are DNA copies made in the lab?
How do primers and special fluorescent nucleotides help determine the DNA sequences?
How does the overlapping of DNA segments allow the entire sequence of a DNA molecule to be read?
3. Show video The Sequencing Race Begins. Ask:
What is the process for sequencing the human genome?
How has the way scientists read the genetic code changed in recent years?
Why is the map of the human genome considered only the beginning of the Human Genome Project?
4. Have students Explore a Stretch of Code and take notes as they do it. Then ask the following and discuss as a class:
What does the majority of the DNA in chromosomes code for?
What is the role of gene promoters like TATA boxes?
How does the "machinery" of the cell know where to begin reading the gene?
What are exons, and what is their function in the chromosomes?
What are introns, and what do they do? What happens to them when DNA is transcribed into mRNA?
What are the roles of "hitchhiking" and ancient code in human DNA, and where did they come from?
How alike is the DNA from two different humans?
What is a gene, and what role do genes play in the human body?
5. Show the video HIV Immunity to examine some of the benefits of mapping the human genome. Ask:
What are outliers, and what is their value in understanding disease?
How can a genetic mutation be advantageous?
How is the knowledge of mutations being used to combat the HIV virus?
6. Show the video Genetic Variation and discuss the following:
Whose genes are being sequenced in the two human genome projects?
Are these genes representative of the human species? Why or why not?
What is the percentage of genetic difference between any two humans?
What does the similarity of basic functions between different organisms indicate?
7. Finally, have students read the Genome Facts document. Have students use these facts and what they have learned about the Human Genome Project to create a series of answers and questions for a Jeopardy quiz show. (

Purple flower color (P) is dominant over white flower color (p) in pea plants. A heterozygous pea plant with purple flowers is crossed with another heterozygous pea plant with purple flowers.
What will be the phenotypes, and probabilities of their offspring?
Question 11 options:
75% purple and 25% white
100% purple
100% white
50% purple and 50% white
Answer:
75% purple and 25% white
Explanation:
When a punnett square is drawn to predict the phenotypes of the pea plants offspring:
- only 1 out of the 4 squares gave the result for the offspring to have white flowers (1/4 = 25%)
- 3 out of the 4 squares gave results for the offspring to have purple flowers (3/4 = 75%)

Question 9 options:
Box 1
Box 1 and box 2
Box 1 and box 3
Box 2 and box 3
Answer:
Box 1 and box 3
Explanation:
[tex]\huge\boxed{\textbf{Box 1 and Box 3}}[/tex]
_____________________________________[tex]\Large\textbf{Phenotype:}[/tex]
It is the physical appearance of the trait, whether the plant has Long stem or short stem.
[tex]\Large\textbf{Genotype:}[/tex]
A genotype refers to the genetic characteristics of an organism's trait, if it is heterozygous or h o m o-zygous, recessive or dominant. This question is basically based on the Genotype, asking for the heterozygous plants which is a genotypic characteristic.
_____________________________________Alleles:Allele Long stem A is dominant over short stem a
Genotype of Parent Pea PlantsPea Plant 1 has genotype Aa
Pea Plant 2 has genotype aa
_____________________________________[tex]\Huge\text{Question:}[/tex]The question asks for how many heterozygous plants are present in the punnet square of pea plant 1 and pea plant 2.
Heterozygous PlantsHeterozygous Plants means those plants which have two different alleles that means One dominant allele (i.e. A here) and One recessive allele (i.e. a here). These Organisms inherit a different version from each parent. In a heterozygous genotype, the dominant allele overrules the recessive one.
If we look at the punnet square given in the attachment, the Box 1 and 3 have genotype Aa which is a HETEROZYGOUS DOMINANT PLANT while box 2 and 4 have a genotype aa which is a HOMO-ZYGOUS RECESSIVE PLANT thus the answer is Box 1 and 3

Freshwater can be renewed, but environmentalists consider it nonrenewable. Why is there a contradiction in classification?
Freshwater is recycled through the use of irrigation, bathing, and everyday use.
Freshwater is easily polluted or depleted before it can be replaced.
Freshwater evaporates and condenses, and then precipitation returns it to the lakes.
Freshwater is highly affected by global warming, and is quickly evaporating.

A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?
Answer:
1.49 m/s; 5.367 × 10⁶ m/hr
Explanation:
Calculations: (This was my thought process, sorry)
386400 km ÷ 72 hr ≈ 5367
5367 × 1000 = 5.367 × 10⁶
5.367 × 10⁶ ÷ 3600 ≈ 1.49 m/s
About 5367 km/hr or 5.367 × 10⁶ m/hr or 2.592 × 10⁵ m/s
Have a great day!
