Gregor mendel concluyo que cada guisante tiene dos unidades para cada rasgo y cada gameto cotiene una unidad . Las unidades de mendel se conocen ahora como
Answer:
Las unidades de Mendel se conocen ahora como GENES
Explanation:
Durante sus experimentos, Mendel demostró que las características de las plantas de guisante (por ejemplo color de la flor, color de la semilla, forma de la semilla, altura de la planta, etcétera) eran heredadas, y denominó "elementos" a las unidades portadoras de dichas características. Es decir que cada elemento o unidad discreta, era el responsable de que la planta exprese una u otra característica. Estableció que estos elementos se redistribuían independientemente uno de otro, generación tras generación. Con el paso del tiempo y el avance de las investigaciones, estas unidades o elementos fueron denominados Genes.

In northern Canada, a population of rabbits was predominantly white in color. The allele for white color is recessive while the allele for gray color is dominant. Over the last several decades, the average annual temperature of this area has increased and the long-term deposits of ice and snow have become scarce. In this case, the frequency of a previously rare allele becomes more frequent in the population. This is an example of
Answer:
The options are
A) nonrandom selection.
B) disruptive selection.
C) directional selection.
D) stabilizing selection.
The answer is C)directional selection.
Explanation:
Directional selection is a type of natural selection and occurrence in population genetics. It involves a phenotype which is most extreme being chosen over forms of phenotypes. It occurs over a period of time when the allele frequency completely aligns in the pattern of the extreme phenotype.
This explains why the frequency of a previously rare allele becomes more frequent in the population after a certain period of time.

Exotoxins are Question 8 options: only released after a cell is damaged or lysed. proteins. lipopolysaccharides. secretions that always target nervous tissue. antiphagocytic factors.
Answer:
The correct answer is proteins.
Explanation:
The exotoxins are proteinaceous in nature, they are the toxins, which are discharged from a living bacterium and are also discharged at the time of bacterial lysis. The exotoxins harm humans, however, not all exotoxins generated harm human beings.
Some are even created to perform an essential function in bacteria physiology like regulating functions of the cell, resisting bacteriophages, or quorum sensing. The three prime kinds of exotoxins are type I exotoxins or superantigens, type II toxins or exotoxins that damage host cell membranes, and type III toxins or A-B toxins that interfere with the function of the host cell.

Answer:
Similar rock types are found across continents
Explanation:
Can I have brainliest?
Similar composition of rocks are present across continents that support the theory of continental drift.
Similar rock types are found across continents is the evidence that support the continental drift theory because at the boundaries of two continent there must be similar type of rock present. Scientist Alfred Wegener presented Continental drift theory in the early 20th century.
Wegener noticed similarities between two continents when he pieced together maps of Africa and South America. He noticed that mountain ranges present on both continents line up to each other which means they are made of similar type of rock so we can conclude that similar types of rock are present across continents.

In some parts of Africa, the frequency of heterozygosity for the sickle cell anemia allele is unusually high, presumably because this reduces the frequency of malaria. Such a relationship is related to which of the following?
a) Mendel's law of independent assortment
b) Mendel's law of segregation
c) Darwin's explanation of natural selection
d) Darwin's observations of competition
e) The malarial parasite changing the allele
Answer:
The correct option is C.
Explanation:
According to Darwin's Law of Natural Selection, a gene that benefits the organism and helps it produce healty offspring so that it can survive is supported by natural selection and will receive a positive feedback over.
The fact that the heterozygosity for sickle cell anemia helps with the survivability of malaria, which is a deadly disease, suggests that the heterozygosity is favored by the law of natural selection.

Damage to Schwann cells would result in Group of answer choices loss of the structural framework of the brain decreased speed of conduction ability to produce scar tissue at the site of an injury increased axoplasmic flow
Answer: decreased speed of conduction.
Explanation:
Schwann cells are type of cells of the peripheral nervous system that produce myelin sheath around neurosonal axons thereby increasing the saltatory function of neurons.
If Schwann cells are damaged it result in blockage of electric conduction which will produce secondary demeylination and resulting in shock or toxic immune shock.
Schwann cells produce myelin sheath will help to increase saltatory conduction but when it is damaged it will decrease conduction and result in shock.

Which of these would be considered a transgenic organism? a human treated with insulin produced by E. coli bacteria a rat with rabbit hemoglobin genes a bacterium that has been treated with a compound that affects the expression of many of its genes a fern grown in cell culture from a single fern root cell a houseplant propagated from the cuttings of another houseplant
Answer:
a rat with rabbit hemoglobin genes
Explanation:
When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.
This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.
Thus by transferring to rat ( the DNA for Hb) as the rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.
Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been modified to add certain vitamins to improve the nutritional values.
Genetically modified bananas as edible vaccines are another example

You are at a conference for a fellow scientist who is giving a lecture in a field you
are both researching: human evolution and ancestry. In his lecture, he compares
many of the behaviors of humans and Chimpanzees, and compares the
behaviors of humans and Orangutans. He concludes that we are more closely
related to Orangutans than Chimpanzees. Is he correct?
Answer:
incorrect
Explanation:
This is an incorrect statement as orangutans are the most distant relatives of humans among the Great apes and chimpanzees are the closest.
What is the evolutionary relationship?
The link drawn between different species of organisms considering their evolutionary history is the evolutionary relationship between these species. Genome sequencing is a method to study evolutionary relationship between the organisms of different species.
The humans, orangutans, gorillas and chimpanzees are grouped together in a family called as as the Hominidae. The Genome sequencing of humans, chimpanzees and orangutans revealed that humans and orangutans share about 97% of their DNA. This is much less than humans and chimpanzees which share 99% of their DNA.
Therefore, the statement that humans are more closely related to orangutans than chimpanzees is an incorrect statement.
