Answer and Explanation:
A few characteristics shared by all cockroach species might be useful to identify them.
Their body shape is flattened, wide and oval. Pronotum: There is a big plaque joined to the thorax, composed of three segments. The first segment covers and protects the small head.Head: Small heads carrying two typical long, thin, and flexible antennae used to sense the environment. They also have two big composed ocellus or eyes. The oral structures are adapted to bite, chew, and absorb. Abdomen: The abdomen is composed of 10 segments. Exoskeleton: Their whole body is covered by a hard, resistant exoskeleton, covered with a cerous substance. Receptors: They have many thermal, tactile, and gustatory receptors to sense the environment. Wings: Two pairs of wings. The tegmens are the hard front pair that protects the body and the second pair of wings. The second pair is membranous and used to fly. Legs: Three pairs of robust legs joined to the thoracic segments. The last pair of legs are much longer than the others. All of them have ornaments that look like spines, and might have a sensory function and help the insect to displace through different fields.Related Questions

Answers
Answer:
Protein
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms.
Cell specialization is also referred to as cell differentiation and it can be defined as a biological process through which generic cells transform into specific cell types, so as to enable them perform certain functions within the body of a living organism.
Simply stated, it's the special function or job in the body of a living organism that are associated with cells.
Generally, cell specialization plays a significant role in the development of embryos.
Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell specialization is fundamental and key for the growth and development of a multicellular organism.
Furthermore, cell specialization as a process is most directly regulated by protein; one super regulating protein encourages cell differentiation while the other tries to stop or prevent the process. These proteins are referred to as master regulating proteins or Helix-Loop-Helix proteins.

Answer:
Aerobic metabolism of amino acid requires deamination
Explanation:
Living system can be defined as the internal systems of organisms and how materials circulate within organisms.
Generally, these living systems are self-organized life forms and are known to be very much interactive with their surroundings or environment. Also, living systems are dependent on the flow of information, matter and energy at various levels.
Some examples of living systems in organisms are respiratory system, nervous system, digestive system, and circulatory system.
Additionally, living systems comprises of the following components; cells, organs, muscle, tissues, blood, etc., which are typically used for carrying out various bodily functions such as respiration, digestion, metabolism, etc.
Metabolism can be defined as a set of chemical processes carried out by a living organism such as humans, plants and animals, in order to sustain life.
Aerobic (oxygen-using) metabolism can be defined as a biological process that typically involves the extraction of energy from any carbohydrate source such as amino acids, fatty acids, etc.
Basically, an aerobic metabolism of amino acid is a process that requires deamination.
Generally, proteins comprises of amino acids and it is responsible for maintaining the proper functioning of the body system.
Transamination can be defined as a biochemical process which typically involves the removal of amino groups from amino acids and transferring them to a ketoacid (amino acid without an amine group), so as to form new amino acids.
Basically, transamination is a reversible oxidation-reduction reaction that is responsible for the deamination of amino acids.

An amino acid analyzer is an instrument used to determine a. the sequence of amino acids in a polypeptide chain b. the presence of modified amino acids in a protein c. the identity of N-terminal and C-terminal amino acids in a protein d. the identities and relative amounts of amino acids in a protein
Answers
Answer:
d. the identities and relative amounts of amino acids in a protein
Explanation:
An amino acid analyzer is an automated machine that is used to determine the identities and quantities of amino acids in a given protein, peptide, and cellular samples. It makes use of the ion-exchange chromatography principle to determine the presence of amino acids. When the chromatogram is obtained, the relative amounts are then determined by the analyzer.
Since proteins are made of sequences of amino acids, the identities of proteins can also be obtained through this method. Ninhydrin, in the chromatographic column, reacts with the present amino acids under an ultra violet detector and is then observed at a wavelength of about 440 - 570nm.
In what ways is a eukaryotic cell similar to a city?

Your partner has a cardiac muscle cell and you have a skeletal muscle cell. Which one of you will use your electrode more times in one minute
Answers
Answer: I will use the electrode on the skeletal muscle cell more times in a minute than my partner will.
Explanation:
Based on the information given, an electromyograph tracing can be used on order to know when to use the electrode for the scenario explained.
An electromyograph is simply a machine that is used for the detection and the recording of the electrical potential that's been generated by muscle cells when such muscle cells are activated.
Due to the fact that a skeletal muscle cell while my partner has a cardiac muscle cell, I'll have to use the electrode on the skeletal muscle cell more times in a minute than my partner will.

Suppose D were dominant and d were recessive, and you could label the D allele in the P generation with a radioactive substance that could be inherited over several generations. You create hybrids by mating your radioactive DD individuals to dd individuals. Finally, you cross two F1 individuals (with the Dd genotype). In 1,000 offspring, how many would you predict would be radioactive?
Answers
Answer:
750 offspring
Explanation:
The correct answer would be 750 offspring.
The D allele has been labeled with radioactive substance.
If you cross Dd and Dd:
Dd x Dd
DD Dd Dd dd
3/4 of the resulting offspring would have, at least, the D allele.
Hence, out of 1000 offspring,
3/4 x 1000 = 750
750 would possess the radioactive label.
If Darwin knew of Mendel's work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin's work was accepted?
Answers
Answer:
See explanation
Explanation:
According to Darwin, the determinant of the ability of species to thrive in their environment is their ability to develop favourable characteristics which enable them to survive in their environment. This ability to develop favourable characteristics is called natural selection.
These favourable characteristics are passed on from parents to offsprings and are responsible for the perpetuation of organisms having these favourable characteristics in comparison to other members of the same species.
In relation to Mendel's theory, these favourable characteristics could be regarded as Mendel's factors (currently identified as genes). These factors are units of inheritance passed on from parents to offsprings.
If Darwin had an idea of Mendel's work when he propounded his evolution theory, he could have modified his idea of favourable characteristics to imply genes. This would have made his idea more empirical than speculative and led to a faster world wide acceptance of his ideas.

14). Clonal selection and differentiation of B cells activated by antigen exposure leads to the production of ________. A) large quantities of the antigen initially recognized B) vast numbers of B cells with random antigen-recognition receptors C) long-lived erythrocytes that can later secrete antibodies for the antigen D) short-lived plasma cells that secrete antibodies for the antigen
Answers
Answer:
The correct answer is D) short-lived plasma cells that secrete antibodies for the antigen
Explanation:
Each B lymphocyte has an antigen receptor (BCR: B cell receptor), a surface immunoglobulin (IgM or IgD), that binds to specific domains of the antigen called antigenic determinants or epitopes. Only B lymphocytes with a high antibody affinity for the antigen, and which are capable of processing and presenting it, will be positively selected. In this contact between the two cells, an exchange of chemical signals takes place that leads to the activation, clonal proliferation and differentiation of B cells into two sister subclones: one of antibody-secreting plasma cells, and the other of memory primed B cells. Therefore, only these last positively selected B lymphocytes will survive, proliferate and differentiate into plasma cells, synthesizing and secreting antibodies of a single isotypic class, with a unique specificity and high affinity, improving the ability to adhere to the antigen and, thus , neutralize and destroy pathogens.
