Answer:
false
Explanation:
You are studying the genomes of deep sea organisms when you come across a brand new species of lantern fish. In the lab, you measure the percent of nucleotides in the nucleus that contain adenine as their base and that percent is 30%. 10. Calculate the percent of thymine nucleotides: _______________ 11. Calculate the percent of guanine nucleotides: _______________ 12. Calculate the percent of cytosine nucleotides: _______________
Answer:
Thymine = 30%
Guanine = 20%
Cytosine = 20%
Explanation:
DNA is a double-stranded molecule made up of long chains of nucleotides (A, T, G, C). Each chain is the strand. However, According to Chargaff, the amount of adenine in a DNA is equal to the amount of thymine while the amount of guanine equals the amount of cytosine. That is:
(A = T) + (G = C) = 100%
All together, they all make up 100%. According to this question, the percent of nucleotides in the nucleus was measured to contain adenine as their base which is 30%.
If Adenine is 30%,. Then Thymine is 30% as well.
A = T = 30+30 = 60%
Hence,
60% + G + C = 100%.
G + C = 100 - 60
G + C = 40%
Since, G = C, 40/2 = 20%. Hence, G = 20% while C = 20%
All together,
A = 30%
T = 30%
G = 20%
C = 20%

Answer: A
Explanation:
Ligand gated means controlled by the _______ or signal molecule. If the door is closed, certain ____ are blocked from entering the cell. When the ___________ or signal molecule is attached, the door is open for certain _____ to enter the cell. These types of receptors are important in the __________ _____________.
Answer:
ligand; molecule; ligand; molecule; nervous system
Explanation:
Ligand-gated ion channels are membrane proteins that interact with ligands (molecules) and open in response to this binding. In the nervous system, these channels are activated by neurotransmitters (ligands) that regulate synaptic transmission between nerve cells (neurons). Neurotransmitters are signaling molecules clustered close to the cell membrane of axon terminals in presynaptic neurons. For example, glutamate is a ligand neurotransmitter that binds to ion channels and thus stimulates synaptic activity in the mammalian brain.
Why is evolution against religion?

Explanation:
identify the individual who most likely exhibits symptoms of cystinuria
Answer: Individuals with a high concentration of cysteine in their urine, show symptoms of cystinuria.
Explanation:
Cystinuria is an hereditary and rare disease in which stones of an amino acid called cystine form mostly in the kidney but also in the ureter and bladder. This is a dimeric amino acid which is formed by two cysteine molecules linked by a disulfide bond. L-cysteine is a non-essential sulfuric amino acid found in a wide variety of foods, some of which are proteins. This condition is passed from parents to children so it is hereditary, the person must inherit the defective gene from both parents.
Cystinuria is caused when there is a high concentration of cystine in the urine. Normally, most cystine dissolves, enters the kidneys and returns to the bloodstream. However, people with cystinuria have the genetic defect that interferes with this process. This condition is due to a defective transport of cystine in the apical membrane of the intestinal epithelium and proximal renal tubule. The result is an absence of cystine reabsorption in the renal proximal tubule producing an excess of cystine in urine and with the consequent formation of kidney stones. Cystine stones are very difficult to remove by lithotripsy unlike the rest of the stones. Therefore, a non-invasive therapy should be carried out to prevent the recurrence of stone formation. This therapy would be based on a high intake of liquids, alkalization of urine, and use of chelating agents. In order to preserve kidney function, a combination of these three therapeutic measures is necessary to reduce both the recurrence and the morbidity of the disease.

Describe: UAG (as well as UAA and UGA) is an example of a stop codon. Molecules called release factors bind to stop codons. Place the release factor on the mRNA molecule.
Answer and Explanation:
UGA, UAG and UAA are the stop codons in the genetic code. During translation, these stop codons signal the end of the polypeptide chain. These codons do not code for an amino acid. Therefore they are called termination codons or nonsense codons. These stop codons have been called as ochre (UAA), amber (UAG) and umber or opal (UGA). Richard Epstein and Charles Steinberg revealed Amber (UAG). They named it amber while remaining two stop codons named as ochre (UAA) and opal (UAG) to maintain the theme of ‘colors names’. Stop codons release the new polypeptide chain from the ribosome, during protein synthesis. This happens because there are no tRNAs with anticodon corresponding to the stop codon.

write a short note on gender issues and mites associated with female infanticide
Answer:
gender issues include all aspects and concerns related to women's and men's lives and situation in society, to the way they interrelate, their differences in access to and use of resources, their activities, and how they react to changes, interventions and policies.
female infanticide is the deliberate killing of newborn female children. In countries with a history of female infanticide, the modern practice of sex-selective abortion is often discussed as a closely related issue. Female infanticide is a major cause of concern in several nations such as China, India and Pakistan. It has been argued that the low status in which women are viewed in patriarchal societies creates a bias against females.
In 1978, anthropologist Laila Williamson, in a summary of data she had collated on how widespread infanticide was, found that infanticide had occurred on every continent and was carried out by groups ranging from hunter gatherers to highly developed societies, and that, rather than this practice being an exception, it has been commonplace. The practice has been well documented among the indigenous peoples of Australia, Northern Alaska and South Asia, and Barbara Miller argues the practice to be "almost universal," even in the West. Miller contends that female infanticide is commonplace in regions where women are not employed in agriculture and regions in which dowries are the norm. In 1871 in The Descent of Man, and Selection in Relation to Sex, Charles Darwin wrote that the practice was commonplace among the aboriginal tribes of Australia.
In 1990, Amartya Sen writing in the New York Review of Books estimated that there were 100 million fewer women in Asia than would be expected, and that this amount of "missing" women "tell[s] us, quietly, a terrible story of inequality and neglect leading to the excess mortality of women." Initially Sen's suggestion of gender bias was contested and it was suggested that hepatitis B was the cause of the alteration in the natural sex ratio. However it is now widely accepted that the numerical worldwide deficit in women is due to gender specific abortions, infanticide and neglect.
In seventh-century Arabia, before Islamic culture became established, female infanticide was widely practiced. This is attributed by scholars to the fact that women were deemed "property" within those societies. Others have speculated that to prevent their daughters from a life of misery, the mothers would kill the child. With the arrival of Islamic rule the practice was made illegal.

In addition to the movement of carbon through Earth's systems, Francine also wants her model to show how much carbon is stored in reservoirs or sinks. Which of these aspects of the carbon cycle could she add to her model to start building a more quantitative model? Select all that apply. A. The process of photosynthesis moves carbon from the atmosphere to the biosphere. B. About 550 gigatons of carbon is stored in plant biomass. C. The ocean is the greatest carbon sink, storing about 38,000 gigatons of carbon per year. D. Geologic processes such as eruptions move carbon from the geosphere to the atmosphere.
Answer:
A. The process of photosynthesis moves carbon from the atmosphere to the biosphere.
The ocean is the greatest carbon sink, storing about 38,000 gigatons of carbon per year.
D. Geologic processes such as eruptions move carbon from the geosphere to the atmosphere.
Explanation:
Photosynthesis is a process in which carbondioxide gas that is present in the atmosphere moves into the plant body for the production of food in the presence of sunlight. Volcanic eruption releases high amount of carbondioxide and carbonmonoxide gases in the atmosphere. The ocean is the greatest storage of carbon, storing about 38,000 gigatons of carbon per year.

Dancing lemurs have an upright posture with legs that are much longer than their arms. They are great aerial acrobats as they swiftly leap from tree to tree. On the ground, they are not able to walk on their four legs instead they perform a sideways bounce on their two legs while holding their arms out for balance, mimicking their leaps from tree to tree. This is an example of ___________.
Answer:
Suspensory locomotion (suspensory behavior)
Explanation:
Suspensory locomotion, also known as suspensory behavior, is a concept that refers to several specialized forms of locomotion observed in some primates, and in other arboreal mammals, which involves hanging the body among tree branches, thereby distributing the body weight to different branches of the trees. Suspensory locomotion includes three specialized types of locomotion: brachiation, climbing, and bridging. It is an adaptive strategy that enables suspensory animals to travel faster and avoid predators during arboreal movement and foraging. Some examples of suspensory primates include, among others, lemur, spider monkey, Bornean orangutan, etc.

Answer:
The allele combination for a trait.
Explanation:
the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes.
In microscopy, the term resolution In microscopy, the term resolution refers to the ability to distinguish fine structure and detail in a specimen. is only observed in stained specimens. refers to magnification when using the electron microscope. is the same as the total magnification of a specimen. is improved when longer wavelengths of light are employed.
Answer:
refers to the ability to distinguish fine structure and detail in a specimen
Explanation:
Resolution can be defined as the capacity of a microscope to distinguish detail. Resolution can be measured as the minimum distance between two distinct objects of a specimen which can still be observed as separate entities. Some important factors influencing microscope resolution include 1- objective numerical aperture, which is related to the angles of light that are collected by a lens (can be improved by using immersion oil), 2- degree of aberration correction, 3-magnification (i.e., degree of visual enlargement of an observed object), 4- contrast methodology, etc. In a light microscope, for example, the maximum resolution that can be reached is 200 nanometers (nm), being this limited by the wavelength of light waves due to diffraction, while the maximum magnification is generally x1500.
