Classifying things by observation can best be done by using a dichotomy wedge key taxon

Answers

Answer 1
Answer:

Classifying things by observation can best be done by using a  : Taxon

Taxon divided organisms into different groups based on their unique similarities, and these similarities can be recognized by observing parts and behavior of the organisms. For example, Organisms generally divided into two groups. Those who have a backbone (vertebrata,  such as mammals and reptiles ) and those who don't have backbones (such as arthropoda)

This is the best way to classifying the organisms because the similarities between them do not exist in their backbones alone. This give more room/possibilities for the classification. For example, The organisms could also be classified by other similarities (such as how they obtain food, their body structure, how they reproduce, etc)

Answer 2
Answer:

The correct answer is Taxon.

Taxon - a unit of classification; element taxonomy group classification level taxonomic rank used in the biological classification. The concept is used mainly in biological taxonomy, where the group of organisms taxon understand, united on the basis of generally accepted methods of classification, interconnected by a degree of kinship, and sufficiently isolated from other groups that it could assign certain taxonomic category ( taxonomic rank) - species, genus, family, and so on.

Which of the following is True for valence electrons?A) Valence electrons are always located in the innermost energy level
B) Each element in the periodic table has a different number of valence electrons.
C) Valence electrons may be lost or gained by an atom when bonding occurs with another atom
D) When atoms collide with other atoms, they bond automatically

Answers

Answer: Option (C) is the correct answer.

Explanation:

Electrons present in the outermost shell of an atom are known as valence electrons.

For example, atomic number of calcium is 20 and its electronic configuration is 2, 8, 8, 2. This means that there are 2 valence electrons in a calcium atom.

These valence electrons can be lost or gained by an atom according to the octet rule and ability to gain stability.

Hence, we can conclude that the statement valence electrons may be lost or gained by an atom when bonding occurs with another atom, is True for valence electrons.

Valence electrons may be lost or gained by an atom when bonding occurs with another atom. The correct option is C.

Valence electrons are the electrons in the outermost energy level, also known as the valence shell, of an atom. These electrons are involved in the bonding behavior of atoms, determining how they interact with other atoms to form chemical compounds.

When atoms come into contact and form chemical bonds, valence electrons can be shared, transferred, or rearranged between the atoms.

This process occurs to achieve a more stable electron configuration for each atom involved.

In some cases, atoms may lose valence electrons to become positively charged ions.

This occurs when an atom has fewer valence electrons than the stable, full outer electron shell configuration. These positively charged ions are called cations.

Thus, the correct option is C.

A woman who has blood type A positive has a daughter who is type O positive and a son who is type B negative. Rh positive is a trait that shows simple dominance over Rh negative and is designated by the alleles R and r, respectively. A third gene for the MN blood group has codominant alleles M and N. Which of the following is a possible partial genotype for the son?
A) IBIB
B) IBIA
C) ii
D) IBi
E) IAIA

Answers

The answer is D) IBi

A mother has either AA or AO genotype. Since her daughter has OO genotype, the one O allele is from a father and one is from the mother.  Thus, mother must have allele O. So mother's genotype is AO.

A mother with AO genotype will pass to her son either A or O allele. Since son is type B negative, it could inherit from mother only O allele. Son's genotype is BO. This means that he inherited from the father B allele.

Talking of Rh, her son is type B negative. A negative Rh phenotype contains both recessive alleles r.
Therefore, the son genotype is BOrr. 
In terms of the alleles for the I locus, it can be represented as I^(B)i.

Which element is found in nucleic acids but not in proteins?

Answers

Phosphorus is the element found in nucleic acids but not in proteins.

Further Explanation

Proteins  

  • Proteins are one of the major biomolecules that exists in nature.
  • They are made of amino acids which are the building blocks. Amino acids contain four different elements which include;
  1. Hydrogen  
  2. Oxygen  
  3. Nitrogen
  4. Carbon
  5. Some amino acid contains sulfur element.

Nucleic acids

  • Nucleic acids are one of the four major bio-molecules in nature. Nuclei acids is divided into two; RNA and DNA.
  • The building blocks of nucleic acids are Nucleotide bases which are made by a nitrogenous base, a sugar and a phosphate group.

DNA  

  • DNA is a nuclei acid that is responsible for carrying genetic information in living organisms.
  • It is through DNA that genetic information is passed from one organism to another through the process of DNA replication.
  • Additionally, it carries the information that is used to make proteins which performs various functions in living cells.
  • Each Nucleotide in DNA contains a nitrogenous base, a deoxyribose sugar, and a phosphate group.
  • DNA molecules are made up of nitrogenous bases; Adenine, Guanine, Cytosine and Thymine.

RNA

  • Ribonucleic acid (RNA) is a type of nucleic acid, a molecule that plays a major role in the flow of information from the DNA to the proteins. For a gene to be expressed information has to be passed through the RNA.
  • Each nucleotide in RNA contains a nitrogenous base, a ribose sugar, and a phosphate group.
  • Nitrogenous bases in RNA includes; Adenine, Guanine, Cytosine and uracil. Thymine in DNA is replaced with Uracil.

The element is found in nucleic acids but not in proteins are the Phosphorous.

Nucleic acids are polynucleotides, which are long chainlike polymers made up of essentially identical nucleotide building components. Each nucleotide is made up of a nitrogen-containing aromatic base that is linked to a pentose (five-carbon) sugar, which is then linked to a phosphate group.

Proteins are composed of hundreds or thousands of smaller units known as amino acids that are linked together in lengthy chains. A protein is made up of 20 different types of amino acids that can be mixed. The sequence of amino acids determines each protein's distinct three-dimensional structure and function.

Thus, Phosphorous is the element which is found in nucleic acid but not in proteins.

In which ways does the body respond when its temperature is too high?

Answers

Vasodilation , when your body is to hot. Blood capillaries dilate and increase their diameter. More blood flows near the body surface. Excess heat in the body is lost through the conduction and radiation to the environment. Your arm hair also rises. 


The body can respond by :nose bleeds heat flashes passing out sweating.
