A flask filled with water and organic molecules was left open to the air for an hour and then was tightly stoppered. After being allowed to sit for a week, the flask was reopened and checked for living organisms. Only anaerobic bacteria were found living in it. Which of the following can be assumed about the conditions within the flask during the week it sat tightly stoppered? (4 points)
Group of answer choices
There were carbon-based gases in the water.
There was abundant oxygen in the flask.
There was no oxygen in the flask.

Which of the following describes Mendel's law of segregation?
During DNA replication, the alleles separate into haploid daughter cells
Alleles of a trait can never be separated from each other.
During meiosis, the two alleles for a trait separate into different gametes
During meiosis, two alleles that were separated come back together

1. How does your DNA differ from other peoples?how is it similar
2.How does your DNA differ from a strawberries DNA? How is it similar
Answer:
1.DNA is more than 99% similar between any two people. All the differences in how we look, feel, behave and the differences in our health are due to less than 1% difference
2.In humans each of these cells have 2 copies of the DNA, but in strawberries each of these have 8 copies of the DNA that means strawberries have 4 times as many copies of DNA as humans, making it 4 times easier to see.
Explanation:
Which best describes the relationship between digestion and cellular respiration? O A. Digestion breaks foods down to simple sugar molecules, and respiration uses the sugar molecules to produce energy. O B. Digestion creates nutrients from food particles, and respiration uses the nutrients to produce energy. O C. Digestion releases oxygen molecules from food, and respiration uses oxygen molecules to produce energy. D. Digestion produces waste materials, and respiration uses the waste materials to produce energy.
Answer:
Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and then release waste products
For this cell division, you can see that 4 daughter cells are made that have half the genetic information as the original. What type of cell division is this?
a) Diffusion
b) Mitosis
c) Meiosis
d) Photosynthesis
Answer:
The cell division where 4 daughter cells with half of the genetic information of the original are obtained is meiosis (option c).
Explanation:
Meiosis is a type of cell division through which sex cells or gametes are obtained. It is a reductive division, since the daughter cells resulting from the process contain half of the chromosomal charge with respect to the original one.
In the process of meiosis, four haploid cells are obtained from a diploid cell, each of which is involved in the reproduction of the species. This mechanism of division occurs in two stages, called meiosis I and II.
The other options are not correct because:
a) Diffusion: it is a passive trans-membrane transport mechanism.
b) Mitosis: is the cellular division of somatic cells, where the result is two daughter cells identical to the original.
d) Photosynthesis: is the mechanism by which plants obtain energy and nutrients, from solar energy.

Explanation:
Dr. Sanchez and her team have observed an unusual star in the Andromeda galaxy. Their data suggests that the star is being consumed by a nearby black hole. They write a scientific paper about their work and submit it to a scientific journal. Other scientists read their paper and look for the unusual star as well. The other scientists are participating in which activity?
Answer:
so the answer is peer review
Explanation:
Yes, other scientists are participating in this activity not in a direct way but in an indirect way. The scientists are participating in peer review.
What is galaxy?The scientific paper was written by scientists which provide the data and conclusion of entire experiments. To write scientific experiments we need to collect data, frame hypotheses, research methodology, and find out the conclusion are some of the steps to writing a scientific paper.
Testing hypotheses often involves designing experiments. In the given experiment Dr. Sanchez found that star is consumed by a nearby blackhole. But other scientist found the unusual star as well.
This suggests that both scientist thought on different aspect. This suggest peer review.
Therefore, Yes, other scientists are participating in this activity not in a direct way but in an indirect way.

3. If tall eyeballs (T) are dominant to short eyeballs(t),
give the genotypes that are possible for members of Mr.
Krabbs' family.
Tall eyeballs =
1
Answer:
Tt, TT
Explanation:
Dominant genes are genes that express themselves over recessive genes. This are expressed on such individual and are visible phenotypically. While recessive genes are genes whose effect are masked and not expressed. They may be present in the genome of an individual but are not usually expressed.
For an individual with a dominant tall eye ball(T)over short eye ball(t), Tall eye ball will always be expressed as TT having similar allele or Tt with a different allele but in a dominant form.
