Answer:
Without the evaluation of sexual stages, fungi can be classified according to the type of colony they present, the speed of growth, the formation of pigments and the type of coloration.
Explanation:
Although the observation of sexual stages is extremely efficient for the classification of fungi in the laboratory. This type of analysis is not always possible to be carried out. In that case, scientists need to find other methods that allow for the classification of fungi. These methods are carried out with the help of a microscope, where scientists observe the morphology of the fungi and are able to classify them according to the type of colony they present, the speed of growth, the formation of pigments and the type of coloration.

What is the role of DNA polymerase enzymes in replication?
(A) unzipping the double helix by breaking down the hydrogen bonds
(B) adding the free nucleotides to the complementary strand of DNA
(C) splitting the DNA molecule
(D)connecting the fragments on the lagging strand of DNA
Answer:
A
Explanation:
the function of DNA polymerase is to unzip the double helix structure of DNA by breaking down the weak hydrogen bond
Answer:
(B) adding the free nucleotides to the complementary strand of DNA
Explanation:
A DNA polymerase is an enzyme capable of creating new DNA molecules by sequentially adding nucleotides to the three prime (3')-end of a DNA strand. A DNA strand is a polynucleotide chain composed of a linear series of nucleotides, each consisting of a deoxyribose sugar, and phosphate, and a base (i.e., thymine, guanine, cytosine and adenine). Before a cell starts to divide, it needs first to replicate its genetic material by using DNA polymerases that duplicate the cell's DNA during the interphase (S phase). During this process (DNA replication), an enzyme known as helicase unwinds the DNA molecule, which is made up of two antiparallel strands oriented in opposite 3′-5′ directions to each other. Subsequently, each strand is used as a template for its replication through DNA polymerases that can add nucleotides (one at time) to an existing short fragment of RNA, i.e., the primer sequence, which is paired with the template DNA strand.

2. cleavage and color
3. hardness and streak
4. greasy feel and composition
The physical properties of graphite which makes it good for pencils is ;
( 3 ) hardness and streak
Graphite is made up of carbon atoms which are held together by van der waals forces ( weak force ). They are soft and slippery which is why graphite is used in the manufacture of lubricants. while graphites are used for the manufacture of writing materials such as pencils because of its hardness and streak
Hence we can conclude that the physical properties of graphite which makes graphite good for the production of pencils are hardness and streak

g An Hfr strain is produced when Select one: A. an F episome is transferred to a new cell. B. an F episome leaves the E. coli chromosome. C. an F episome leaves the host chromosome and removes some of the host chromosome. D. an F episome integrates into the E. coli chromosom
Answer:
A. an F episome is transferred to a new cell.
Explanation:
Hfr strains arise from the integration of the plasmid into the bacterial cell in one of several ways such as the recombination of events. Most commonly are formed by the UV-induced integration of E coil F factor. It tries to transfer a copy of the F factors as well the entire chromosome to the recipient bacterium.Describe how oxygen is transported in blood, and explain how temperature, pH, BPG, and affect oxygen loading and unloading.
Solution :
The flow of oxygen in the blood is been transported by two ways :
1. in plasma 1.5%
2. bound to hemoglobin 98.5%
As the oxygen loads in the body, affinity of the Hb makes the oxygen loading very efficient in the blood. The Hb molecule gets saturated when all the 4 hemes are oxygen binded.
The decreased pH weakens the hemoglobin oxygen binding in the tissues.
Higher temperatures in the oxygen means a lower affinity and thus more oxygen is released and so the oxygen unloads.
Increase in the temperature, the BPG and the modification of the structure in the hemoglobin decreases the affinity for the oxygen and further enhances the unloading of the oxygen in the blood.
Sigmoidal plots of activity versus substrate concentration are exhibited by a. holoenzymes. b. Michaelis-Menten enzymes. c. allosteric enzymes. d. monomeric enzymes. e. isozymes.
Answer:
The correct answer is C
Explanation:
Allosteric enzyme is an enzyme that has more than one active site on the surface of the enzyme. Generally, the binding to one of these active sites affects the affinity of the other active sites on the enzyme; this causes the enzyme not to follow the Michaelis-Menten's enzyme kinetics. Thus, when the activity versus substrate is plotted on a graph, a sigmoidal curve shown instead of an hyperbolic curve (like other enzymes).

Respuesta corta: Produciendo un sentimiento de satisfacción.
Explanation
En el texto se hace referencia a una investigación para analizar la relación entre las redes sociales y el cerebro de los adolescentes. Para ello los investigadores utilizaron imágenes magnéticas del cerebros de los 32 adolescentes estudiados. Una vez terminaron el estudio se dan cuenta que "una estructura del cerebro, llamada núcleo accumbens, se activa más cuantos más likes tuviera una imagen". Además, el autor del texto agrega que "Esto es interesante si se tiene en cuenta que este órgano nervioso es el responsable de que experimentemos momentos de placer intensos al ganar un premio, comer helado, etc". De acuerdo a lo anterior se puede interpretar que las redes sociales influyen en el cerebro de los adolescentes debido a que produce en ellos un sentimiento de satisfacción o reconocimiento a recibir "likes" de otras personas. Además, este sentimiento se puede interpretar como aprobación por parte de las demás personas.

Albinism is a recessive trait where an individual does not produce the pigment melanin. A man and woman who both produce melanin have one child out of three who has albinism. What are the genotypes of the man and woman
Albinism is a recessive trait where an individual does not produce the pigment melanin. Albinism is an autosomal disease where the gene which is expressed here is having albinism which is the cause of heterozygous condition.
What is the heterozygous ?
Heterozygous is the condition where the genes in the alleles are different to each other where one has a dominant character and one has a recessive character. The genotypes of the woman and man decide the genotype of the offspring.
The genotypes of the man and woman is heterozygous where the dominant once out of 3 will have the dominant traits for the albinism. The condition will have to be heterozygous as in the Ia Ii gene where the gene for the albinism will be i gene.
The same genotype for the male where the Ib i gene in which i i the albinism carrying gene here the ii condition of the gene will express the albinism.

Group of answer choices
perfusion
percolation
ventilation
diffusion
Answer:
ventilation
Explanation:
Breathing, also known as ventilation, is the process of moving air or water in order to facilitate the gas exchange between the external and internal (body) environment, mostly to eliminate carbon dioxide (CO2) and bring in oxygen (O2). For example, fish are aquatic animals that need to run water over their gills to get the O2 that they need to survive (gills are organs that create a large surface area for ventilation). Moreover, insects ventilate their tracheal system to get O2. Finally, terrestrial vertebrates (i.e., amphibians, reptiles, birds, and mammals) use organs called lungs to exchange O2 and CO2 between their cells and the external environment.
