True or False?
which scenario brakes the law of segrigation
Answer:
In any trisomy disorder, a patient inherits 3 copies of a chromosome instead of the normal pair. This violates the Law of Segregation, and usually occurs when the chromosomes fail to separate during the first round of meiosis. A heterozygous pea plant produces violet flowers and yellow, round seeds.

Hoagland found that some ions were absorbed only if oxygen was bubbled through
the pond water. Explain this observation.
Answer:
needed for respiration for active transport
Explanation:
oxygen is needed for respiration which provides energy for active transport of the ions into the plant.
active transport is needed to move the ions into the plant as there are higher levels of concentration already in the cell sap.

Hoagland found that some ions were absorbed only if oxygen was bubbled through the pond water needed for respiration for active transport.
What is the role of oxygen in respiration?Oxygen has been needed for respiration which provides energy for active transport of the ions into the plant and active transport has needed to move the ions into the plant as there are higher levels of concentration already in the cell sap.
During aerobic cellular respiration, glucose reacts with oxygen, forming ATP ( Adenosine triphosphate) that can be used by the cell. Carbon dioxide and water are created as byproducts. The overall equation for aerobic cellular respiration is in cellular respiration, glucose and oxygen react to form ATP ( Adenosine triphosphate).
Adenosine triphosphate has an organic compound which gives energy to living organisms to drive many operations in living cells. such as muscle contraction, muscle pumps, nerve impulse propagation, condensate dissolution, and chemical synthesis.
Therefore, Hoagland found that some ions were absorbed only if oxygen was bubbled through the pond water needed for respiration for active transport.

identify which conditions are necessary for hardy–weinberg equilibrium, and which conditions lead to evolution.
Answer:
The conditions to maintain the Hardy-Weinberg equilibrium are: no mutation, no gene flow, large population size, random mating, and no natural selection. The Hardy-Weinberg equilibrium can be disrupted by deviations from any of its five main underlying conditions.
Hope that help
Explanation:
For the principle of Hardy Weinberg where the principle is saying that the genetic variations remain constant until any disturbing factors come up. The conditions are like no gene flow, natural selection and many more.
What is the theory of fittest ?The theory of fittest says that the species that are able to adapt the variations and able to adapt to the changes that are taking place in nature are selected by nature for the survival and are fit to live.
The conditions are necessary for hardy–Weinberg equilibrium, and conditions lead to evolution are as following :
The species should not have the mutations that the species should have the same copy of the genome with no change in the genome.
Random mating that is the individuals that are selected by the nature or who randomly mate make no change in the nature.
The population size should be bigger that is the individuals should be bigger in size and the change thus is small in size.
No selection
No gene flow are the various conditions that need to be followed in order to maintain the equilibrium as per the law.

Explanation:
Blood cells move throughout the body in veins and arteries, carrying oxygen to cells and carrying carbon dioxide waste away. The lungs take in oxygen from the environment to be diffused into blood cells and exhale the carbon dioxide waste. If you stop breathing, even momentarily, the amount of oxygen in your blood will drop, your brain will quickly increase its messages to your lungs, and you will inhale, increasing the amount of oxygen in your lungs.

Answer:
Cell
Explanation:
Hi there!
A cell is the smallest unit of a living thing. However, a cell, much like a person, must have other parts inside of it in order to function (it can't function by itself).
The nucleus, ribosomes, and mitochondria are all structures inside of a cell; they are some of the organelles inside of a cell, which help the cell do specific jobs, a bit like how a machine needs special pieces in order to do certain tasks.
Therefore, a cell is the structure that includes all of the others, since the other structures are organelles that help the cell function, and they are all inside of the cell.

The double helix model of DNA explained Chargaff's rules because
A.
adenine could hydrogen-bond with thymine and guanine could hydrogen-bond with cytosine to hold the helix together.
B.
a helix repeats itself many times over, so the four bases in DNA can repeat themselves many times.
C.
adenine and thymine are found in one strand of the double helix and guanine and cytosine are found in the other strand.
D.
adenine could change places with thymine while guanine could change places with cytosine.
The double helix model of DNA explained Chargaff's rules because adenine and thymine are found in one strand of the double helix and guanine and cytosine are found in the other strand. Therefore, the correct option is C.
Since adenine (A) always associates with thymine (T) and guanine (G) always associates with cytosine (C), the double helix model of DNA provided an explanation for Chargaff's rules. This complimentary base pairing allows the two strands of the DNA double helix to fit together. According to Chargaff's criterion, DNA contains an equal number of A and T as well as G and C atoms.
The DNA molecule can be stabilized by hydrogen bonds formed between A–T and G–C base pairs, as shown by the double helix structure. Given that A and T are located in one strand of the double helix and G and C are found in the other, the double helix model of DNA provides a structural basis for understanding why Chargaff's rules are valid.
Therefore, the correct option is C.

Explain the method scientists use to study how Earth's atmosphere and climate have changed during the past million
years
Answer:
Scientists study Earth’s climate and the ways that it changes in a variety of different ways, using satellite, instrumental, historical, and environmental records. One challenge of using satellite and instrumental data is that their lifespans have been rather short when compared to Earth’s life. The satellite record is only a little over 20 years old and the instrumental record only extends back into the 19th century. Both of these records can be too short to study certain climate processes that occur over hundreds to thousands of years.
