Chemists have determined that elements with atomic numbers greater than 92 are all
radioactive. In general, their half-lives are much shorter than the age of the universe. This
means that they no longer exist in nature and have all been artificially produced by
scientists in nuclear reactions.
Elements 93 through 105 in the periodic table have been created and named, and
scientists have claimed discovery of elements 106 and 107. The transuranium elements,
as they are called, become less stable as the atomic number and mass increase. For
example, element number 93, neptunium, has a half-life of two million years, while
element number 104, kurchatovium, has a half-life of 70 seconds.
The transuranium elements are the heaviest elements that exist and are readily
fissionable when subjected to nuclear bombardment. Chemists studying these elements
and the periodic table predict that stable elements may be found around atomic numbers
114 or 126.
According to the passage, what can we predict about the half-life of element number 105?
It is:
O
A. greater than 2 million years
B. incalculable (not capable of being determined)
C. measured in days or weeks
D. greater than the other transuranium elements
E. less than 70 seconds

Answers

Answer 1

Answer:

B. incalculable (not capable of being determined)

Explanation:

The passage states that elements with atomic numbers greater than 92 are all radioactive and that their half-lives are much shorter than the age of the universe. It also states that elements 93 through 105 in the periodic table have been created and named, but it does not provide any information about the half-life of element number 105 specifically, therefore it is incalculable.

proteins-large complex molecules-are major building blocks of all living organisms. discuss the chemical composition and levels of structures of protiens

Answers

Proteins' chemical composition and structural levels. Proteins are chemical macromolecules made up of monomeric components known as amino acids. Proteins are organized structurally as follows: Primary, secondary, tertiary, and quaternary education are available.

(b) DNA and RNA functions in protein synthesis

Ribosomal RNA, a kind of RNA found in ribosomes and important for protein synthesis, is produced from DNA. As a result, the significance of DNA in protein synthesis is critical: there are no proteins without DNA.

(c) Protein involvement in membrane structure and chemical transport across the membrane

Proteins can work by transporting ions in different ways.

(a) Proteins' chemical composition and structural levels.

Proteins are molecular macromolecules made by manomeric units called amino acids, which have a carboxyl group and an amino group connected to the same carbon in their structure. Proteins must be digested into the amino acids that make them up before they can be assimilated by the body.

Peptide bonds hold the amino acids together. The amino group of one amino acid reacts with the carboxyl group of the other in those linkages.

Proteins are organized structurally as follows:

Primary: The amino acid sequence in the chain with peptide bonds.

Secondary: The spatial organization of a protein's amino acids. They are held together by hydrogen bonds. There are two types: the propeller a and the folded blade b.

Tertiary: A three-dimensional arrangement of the polypeptide chain that is held together by van der Waals forces.

Quaternary: The formation of a protein complex by the union of weak links of arias polypeptic chains.

(b) DNA and RNA functions in protein synthesis

The most significant function of RNA is protein synthesis, in which it copies the genetic order contained in DNA and uses it as a standard in the manufacturing of proteins, enzymes, and other chemicals required by the cell and the organism. It gets to the ribosomes, which work as a kind of molecular protein factory, for this, and it does so in the pattern that the DNA prints on it.

Leber congenital amaurosis (lca) is a type of autosomal recessive hereditary blindness that causes individuals with this disease to lose their vision during childhood. the pedigree below shows the inheritance of lca throughout three generations of a family. True. LCA is an autosomal recessive genetic condition that is passed on to children by parents who have an abnormal copy of the gene.

Inheritance of traits is a decrease in traits that are passed on from parents or parents to their offspring. Some of the characteristics that are passed from parent to child are hair shape, eye color, blood type, and even congenital diseases.

LCA or Leber Congenital Amaurosis is a congenital eye disorder that is present from birth. Babies from birth will lose their eyesight due to an autosomal recessive genetic condition. Babies with LCA inherit two copies of the abnormal LCA gene from both parents. A grandmother who has the normal gene marries a grandfather who has half the abnormal LCA gene So that the child will have half the abnormal or carrier genes, if the child marries someone who has half the abnormal or carrier genes, then it is certain that the third generation will have 100 percent of the abnormal LCA gene so that he will experience blindness from infancy.

What was Dr. Kettlewell's conclusion on his experiment with bird predation on the moths?

Answers

Answer: Dr. Kettlewell concluded that the observed shift in moth coloration was the result of natural selection, with the darker moths being better adapted to survive in heavily polluted environments.

Explanation: Dr. Kettlewell's experiments on bird predation of the moths were conducted in the 1950s and 1960s and focused on the peppered moth, a species that occurs in both light and dark forms. The study found that birds were more likely to prey on the lighter, more visible moths when they rested on trees covered in soot and industrial pollution, while the darker moths were better able to camouflage and avoid predation. Dr. Kettlewell concluded that the observed shift in moth coloration was the result of natural selection, with the darker moths being better adapted to survive in heavily polluted environments.

Answer: wrong colored moths were eaten at twice the rate of the camouflaged moths.

Explanation: Kettlewell's overall position was that natural selection by bird predation on the white colored moths caused the change in moth ratios from 98% white to 98% dark.

Acetone molecules can position themselves similarly to ethanol molecules to form a tight surface with hydrogen bonding.

The body has the ability to detect change, activate mechanisms that oppose it, and maintain relatively stable internal conditions.

Internal conditions, like body temperatures, fluctuate within a specific range but are not completely constant.

Homeostasis is the propensity to maintain a steady, regular internal environment. In addition to temperature, the body regulates homeostasis for a variety of other variables. For instance, it's important to maintain the pH and glucose levels in your blood as well as the different ion concentrations there. You risk becoming seriously ill if these numbers fluctuate too much or too little.

Not simply at the level of the entire body as it is for temperature, but also at multiple levels, homeostasis is maintained.
