The conclusion is that water has moved from the beaker into the bag by osmosis because concentration of solute in the beaker is lower than that in the bag.
What is osmosis?Osmosis is the movement of water molecules across a semipermeable membrane from a solution of low solute concentration to one of high solute concentration.
The concentration of solute in the beaker is lower than that in the bag, therefore, water will move from the beaker into the bag by osmosis.
In conclusion, the solution in the beaker is of lower solute concentration than in the bag.

A scientist uses radioactive nitrogen to label the nitrogenous bases of the DNA of a cell. Then the DNA is allowed to replicate, and the new strands take up non-radioactive bases. Do one, both, or neither of the daughter cells have radioactive DNA? Explain.
I think yes, because from what i knew. When the DNA replicate, it will be same as the original/mother DNA. so it will both have radioactive DNA.
Just think, if only one DNA have radioactive then it wont be dangerous, but it affect the replication DNA, then its different case and will be dangerous for the body. You must've heard that radioactive can be dangerous for the body.
Sorry if im wrong
Answer:
I would say one..
Explanation:
It says the new strands take u non-radioactive bases.. if he only used the radioactive to label one of them then I would say one..

how is the law of mendelian inheritance violated in down's syndrome
Answer:
According to the Law of segregation presented by Mendel, each gamete receives just one copy of every allele randomly. Normally all the cells follow the Mendelian inheritance.
In Down's syndrome, an individual gets 3 copies of a chromosome instead of the normal chromosome pair. This is also known as trisomy 21. It does not follow the law of segregation of Mendelian inheritance as it gets three instead of two.

A variety of opium poppy (Papaver somniferum L.) having lacerated leaves was crossed with a variety that has normal leaves. All the F1 had lacerated leaves. Two F1 plants were interbred to produce the F2. Of the F2, 249 had lacerated leaves and 16 had normal leaves. Give genotypes for all the plants in the F1, and F2 generations. Explain how lacerate leaves are determined in the opium poppy. (Section 5.2)
Answer:
The correct answer is-
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)
2. Two genes, with a dominant allele at either or both loci.
Explanation:
The given information gives THE following data:
Dominant: Lancerate leaves - AABB
Recessive: normal leaves - aabb
F1 has - all Lacerated leaves - AaBb
F2 by selfing F1:
AB Ab aB ab
AB AABB AABb AaBB AaBb
Ab AABb AAbb AaBb Aabb
aB AaBB AaBb aaBB aaBb
ab AaBb Aabb aaBb aabb
Here, 15/16 = lacerate which is 0.94 which is equal to the value of lacerate given in the question - 249/265 = 0.94
And normal 1/16 = 0.062 is almost same as 16/265 = 0.060
Thus, the genotypes of -
F1 - AaBb (lacerate)
F2 - A_B_; A_bb; and aaB_ (lacerate)
- aabb (normal)

In the US, 1 in 1700 Caucasian children will be born with the monogenic hereditary disorder Cystic Fibrosis (CF), a pathology that results in an accumulation of abnormally sticky and thick mucus affecting the lungs and digestive system. Consider a small isolated community in Appalachia where most of the population lives below the poverty level and where adults have a higher rate of CF that the national average since the people tend to marry neighbors. The general practitioner for the county receives a Bill and Melinda Gates Foundation Grant to ascertain how many children in the community inherited cystic fibrosis from their parents. Out of 172 children tested, she finds 38 have CF. Remember that Mendel believed in diagnostic ratios for understanding inheritance outcome although other factors can come into play like assortative mating.

1. Tell what type of interaction is being performed by the following pairs of
organisms. (Commensalism, Mutualism, Competition, Parasitism and
Predation)
6. aphid and rose plant
9. butterflies and flowers
10. birds and worms
7. lion and buffalo
8. coral reefs and fishes
Answer:
6. Parasitism
9. mutualism
10. predation
7. predation
8. mutualism
Explanation:
Living organisms, in their natural habitat, forms certain relationships with one another. These relationships are as follows:
- Mutualism is the association of two organisms in which both organisms benefits from one another in the relationship. Example is butterfly and flower in this question, where the butterfly helps pollinate the flower while the plants provide food source for the butterfly. Another example is coral reefs and fishes where the fishes and coral depend on one another.
- Predation is the kind of relationship in which one living organism called PREDATOR kills and feeds on another called PREY. Examples are the relationship between birds and worms, lion and buffalo where the bird and lion are predators while worm and buffalo are preys.
- Parasitism is the relationship between two organisms in which one organism called PARASITE lives on and derive nourishments from another organism called HOST. In the example of aphid and rose plant where the aphid is the parasite and rose plant is the host.
The type of interaction that is being performed by the following pairs of
organisms include the following:
Aphid and rose plant - ParasitismButterflies and flowers - MutualismBirds and worms- PredationLion and buffalo - PredationCoral reefs and fishes - MutualismAphid and rose plant have a parasitic relationship due to the aphids taking
up vital nutrients from the rose plant thereby resulting in distorted growth.
Butterflies and flowers have a mutualistic relationship as the butterfly aids
pollination of the flowers and also derives food and juice in return.
Birds and worms have a predatory relationship as the birds eat worms for
food and survival.
Lion and buffalo have a predatory relationship as the Lions eat buffalos for
food and survival.
Coral reefs and fishes have a mutualistic relationship as the fishes aids
reproductive ability of the coral reefs while the fishes benefit food and habitat in return.

1. For today’s weather, it’s up to you to decide where the fronts are located. Draw the fronts on the map. Explain your reasoning.
As per the weather map of north America the regions of high and low pressure are given along with the cloudiness and range of temperatures
The warm and fold fonts are affected by the cloud covers and hence affect the temperature of the region. The cold front will be along the borer of 40 and 50°. The northeastern region shows maximum cloud cover and a low pressure. As compared to the western and southern region have have high temperatures and experienced high pressure. The winds will below from the high pressure to low pressure and hence create instability cover the north eastern parts.Hence the fronts are located north east and central zone.

what are the consequences of overdrawal of water?
Answer:
As the water table goes low, water may not be easily obtained leading to it scarcity. Overdrawal of water can also lead to sinking or lowering of the land surface that can make it prone to flooding. Streams and water bodies may also get disconnected due to over-withdrawal of water.
