Approximately one out of every 2,500 caucasians in the united states is born with the recessive disease cystic fibrosis. According to the hardy-weinberg equilibrium equation, approximately how many people are carriers?.
In the US, 4% of white people are carriers of cystic fibrosis.
Explanation: If q2 = 1/2,500, then q =.02, p =.98, and 2pq = roughly.04, or 4%, according to the Hardy-Weinberg equilibrium equation.When the population keeps its genetic variety constant, the Hardy-Weinberg equilibrium equation is applied.
How is the prevalence of cystic fibrosis determined?The disease cystic fibrosis is autosomal recessive. Hardy Weinberg Equilibrium states that q2, which in this case equals 1/2500 and q = 1/50, is the frequency of an autosomal recessive disease in a population. P = 49/50 1 because the frequency of the two alleles (p & q) must be equal to 1.

The hypoxemia , hypercapnia and decreased serum pH is responsible for respiratory failure in case of pneumothorax.
The respiratory failure occur only when partial pressure of PO₂ is less than 50 mm Hg or hypoxemia. It can also be marked when PCO₂ is >50 mm Hg or hypercapnia condition and decreased serum pH below 7.3.
With each exhalation, more and more air becomes trapped in the pleural cavity, compromising the unaffected lung and ultimately leading to the failure of both lungs. This condition is known as pneumothorax.

chloroplasts were only examined and labeled in the spirogyra slide. relate the function of these organelles to explain why they were not present in the onion root tip slide.
The onion fruiting body (bulb), which is utilized for storing energy rather than photosynthesis, is the reason why the clear epidermal cells are found in a single layer and lack chloroplasts.
A big vacuole, cytoplasm, cell wall, cell membrane, and nucleus are all components of a plant cell. Because they are underground, the roots are shielded from the sun. As a result, they are independent of chloroplasts. Organelles found in plant cells called chloroplasts use the photosynthetic process to change light energy into relatively stable chemical energy. They ensure that life on Earth continues.
The two membranes that surround chloroplasts also include a third complex membrane system called the thylakoids, which includes grana and lamellae. In addition, key chloroplast structures include starch grains, plastoglobules, stromules, eyespots, pyrenoids, etc. It is largely agreed that a free-living, photosynthetic cyanobacterium gave rise to chloroplasts before being absorbed by a eukaryotic cell. The majority of the chloroplast proteins are encoded by nuclear genes, and the gene products are carried into the chloroplast through complicated import machinery. Chloroplasts retain a limited genome. The biogenesis and dynamic three-dimensional structure of chloroplasts depend on these activities.

The findings imply that the presence of mania contributes to frontal grey matter loss in bipolar disorder.
The amygdala, hippocampus, and dorsomedial thalamus are the primary subcortical limbic brain areas associated with depression. Depression has been associated with both structural and functional abnormalities in these regions.
Hippocampal volumes have been found to be smaller in depressed people (10, 25). It is generally accepted that bipolar disorder is caused by chemical imbalances in the brain.

If you are neither relaxing or contracting a specific muscle, the amount of ATP is A. staying the same or increasing.
Muscle cells require ATP as a source of energy for contraction and muscle movement. Even when you are setting your muscle to a relaxing mode, you are using some ATP to do so.
However, if a muscle is set in such a state that it is neither relaxing not contracting, hence there is no work being performed by the muscle. At this stage the ATP amount inside this muscle will remain the same and can increase if the neurons bring some extra ATP for the muscle cells to store here.

a key characteristic of aquatic dead zones is . group of answer choices a low concentration of keystone species a low concentration of oxygen a high concentration of urban development a lack of water low concentrations of nitrogen and phosphorus
An important characteristic of aquatic dead zones is a low concentration of oxygen.
Dead zones are areas of water where aquatic life cannot survive due to a lack of oxygen. Dead zones are typically caused by significant nutrient pollution and are especially problematic in bays, lakes, and coastal waters because they receive excess nutrients from upstream sources. Excess nitrogen and phosphorus cause an explosion of algae in a short period of time, a phenomenon known as algae blooms. Algae growth consumes oxygen and blocks sunlight from reaching underwater plants. When the algae dies, the oxygen in the water is depleted.
Aquatic life is unable to survive due to a lack of oxygen.Elevated nutrient levels and algal blooms can also cause drinking water problems in communities near and upstream of dead zones. Toxins released by harmful algal blooms contaminate drinking water, causing illnesses in both animals and humans.

The dominant allele A results in green leaves, aa plants have purple leaves. The dominant allele Dresults in tall plants; dd plants are dwarfed. The dominant allele results in ragged leaf margin; rr plants have smooth leaf margins. A triple heterozygote is test-crossed and the following phenotypes of progeny were observed. # of plants 265 140 90 Phenotype green, tall, ragged green, tall, smooth green, dwarf, ragged green, dwarf, smooth purple, tall, ragged purple, tall, smooth purple, dwarf, ragged purple, dwarf, smooth TOTAL 16 24 70 120 275 1000 1. 16 2. 20 3. 30 What is the distance between D and R? 4. 26 5. 50 What's the distance between A and R? 6. 54 What is the order of the genes? 7.

The dominant allele A results in green leaves and aa plants have purple leaves. The dominant allele Results in tall plants; dd plants are dwarfed. The distances between A and R, R and D, and A and D will be,20 cM, 30 cM, and 50 cM respectively.
We can calculate the recombination frequency (RF) by using the following formula.
RF between 2 genes = (single cross-overs for the two genes + double cross-overs) / total number of organisms
Total number of organisms = 1000
d between the two genes = (RF × 100)
Calculate the RF and distance between A & R
RF = (90 + 70 + 24 + 16) / 1000
RF = 0.2
d among A & R = 0.2 × 100
d among A & R= 20 cM
Calculate the RF and distance between R & D
RF = (120 + 140 + 24 + 16) / 1000
RF = 0.3
d among A & R = 0.3 × 100
d among A & R= 30 cM
The distance between A & D is equal to the sum of A & R + R & D
d among A & D = 20 + 30
d among A & D = 50 cM

What is test cross?
Gregor Mendel used the test cross experiment for the first time in his research on the genetics of characteristics in pea plants. According to Mendel's idea, which is still valid today, every creature has two copies of each characteristic. One was a dominant characteristic, while the other was recessive. If existent, the dominant characteristic would dictate the phenotype, or the phenotypical makeup of the organism.Mendel intended to take these steps to ensure that he was working with a homozygous dominant organism, or one that solely contained dominant alleles. However, the genotype of an organism cannot be determined only from its phenotype. The organism could be concealing a non-expressed, recessive gene. Mendel devised the method of mating this individual with a homozygous recessive individual for the same trait in order to identify this unknown allele.Examples of test cross:

Humans can synthesize 13 of 21 basic amino acids; the remaining 8, which must be included in the diet, are called essential amino acids.
Essential amino acids are those that must be obtained through diet because the body "CAN NOT" produce them. Nine amino acids out of a total of twenty are thought to be essential. An essential amino acid, also known as an indispensable amino acid, is an amino acid that cannot be synthesized by the organism quickly enough to meet its demand and must therefore be obtained from the diet.
Nonessential amino acids, like essential amino acids, can be resynthesized in your body to build new proteins as your cells require.

The two kinds of synthetases catalyze the same global process, the attachment of an amino acid to the tRNA, but differ in where the amino acid is put on the terminal adenosine of the tRNA: Class I enzymes prefer 2' hydroxyl groups, whereas class II enzymes prefer 3' hydroxyl groups.
ARSs catalyze the ligation of amino acids to their corresponding transfer RNAs (tRNAs), and so play a crucial role in protein synthesis. These enzymes can be found in free form or as part of a multi-tRNA synthetase complex in eukaryotic cells (MSC).
