1. Using Mendel's Law of Segregation and Law of
Independent Assortment, explain how meiosis leads to genetic variation.
Answer:
Homologous chromosomes can independently assort along the metaphase plate during metaphase 1, meaning it doesn't not matter the order in which they line up, making it have more diverse possibilities. The law of segregation says that one allele from a gene can go to either gamete randomly, therefore there are 4 genetically different gametes from each parent that can be formed and come together to form a genetically diverse person.

Do you think the vacuum hose is an effective way to remove sea urchins? Why? Explain at least one way this technology can be improved.
Answer:
No, or at least not yet. there small and dont do much improvment. If they were much bigger and sucked better, including some touch-ups here and there, they would have a bigger effect on removing sea urchins.
Explanation:
No
vaccum hoses are quite small in size.They don't suck sea urchins as per requirement.If they would be bigger and have more sucking power then it can be yes.Which tree would survive better if they had the same amount of oxygen, water, soil and sunlight, a redwood or a giant sequoia and why?
the Redwood would survive better
Explanation:
A sequoia would need more resorces to provide enough water high nutrients soil and lots of sunlight to survive yet again a sequoia can survive for thousands of years but they are huge and need lots of resources you get my point so the redwood haves a better chance to survive with the amount a resources redwood needs,

Karen has 47 chromosomes but no apparent abnormalities. What is true about Karen?
O A. She has aneuploidy.
O B. She has monosomy.
O C. She will die young.
OD. She has a cleft palate.
Answer:
A. She has aneuploidy.
Explanation:
remember doing this a while back, got it right.
The statement that is true about Karen's abnormality is that she has aneuploidy. Details about aneuploidy can be found below.
What is aneuploidy?Aneuploidy is a chromosomal abnormality whereby an organism possesses a chromosome number that is not an exact multiple of the haploid number of that organism.
In humans like Karen, the haploid number of chromosomes in each gamete cell is 23. This means that the number of chromosomes that is expected to be in the somatic cells is 23 × 2 = 46 chromosomes.
However, according to this question, Karen has 47 chromosomes but no apparent abnormalities. This suggests that she posseses aneuploidy.

Many farmers and gardeners compost their plant and animal waste. The living material naturally decays in compost bins, forming a dirt-like substance that’s rich in nutrients. The next season, farmers use this substance as a natural fertilizer for their crops.
A biology student has grown tomato plants for several years. Until now, he used an artificial fertilizer formulated for tomato plants. This fertilizer caused his plants to grow faster and taller than they grew in unfertilized soil. The student wants to know whether using natural compost will cause his tomato plants to grow faster and taller than his artificial fertilizer.
Answer the following questions to plan an investigation using the steps of the scientific method and help the student find the answer to his question.
Part B - Whats the students scientific question?
Part C - Construct at least two possible hypotheses for the students experiment
Part D - Choose one hypotheses to make a prediction

What drives subduction at a converging plate boundary?
Answer:
The geologic features related to convergent boundaries vary depending on crust types. Plate tectonics is driven by convection cells in the mantle. ... Subduction begins when this dense crust converges with less dense crust. The force of gravity helps drive the subducting slab into the mantle

Which THREE statements describe how the models of mitosis and meiosis demonstrate genetic continuity?
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.
In Metaphase (Metaphase II of meiosis) the chromosomes are lined up properly, indicating that the chromatids will separate evenly and provide the daughter cells with equal amounts of genetic material.
In Telophase (Telophase II of meiosis) the amount of chromatin present is equal to the amount present during Interphase, indicating that the daughter cells will receive the same amount of genetic material as the parent cell.
Answers: A,B,D
Explanation: :I took the test and got this question right .
The three statements that describes how the models of mitosis and meiosis demonstrate genetic continuity are listed and explain below.
In Anaphase, chromosomes line up in the middle of the cell while the spindle fibres pulls them apart.
Therefore the statement below about anaphase is correct.
Chromosomes are divided up evenly during Anaphase (Anaphase I of meiosis), ensuring that the daughter cells will have the correct number to reproduce.In interphase, the synthesis of DNA occurs where the chromosomes replicates forming two identical copies of DNA.
That is, the cell now has 92 chromosomes which is enough DNA for two cells.
Therefore the statement below about interphase is correct.
In Interphase the chromosomes have duplicated, indicating that there will be enough genetic material to separate into daughter cells capable of reproduction.In the prophase, the mitotic apparatus appears; this consists of two centrioles separated by the mitotic spindle which is formed from microtubules.
The formation of these mitotic spindle fibres indicates that the chromosomes will be split evenly.
Therefore the statement below about prophase is correct.
In Prophase (Prophase I and II of meiosis) the spindles form, indicating that the chromosomes will be split evenly, and the daughter cells will receive the appropriate amount of genetic material.Learn more here:
