Answer:
Verdadero
Explanation:
Sabemos que los caracteres dependen de los genes. Y los genes pueden presentarse en forma de alelos dominantes, o alelos recesivos. La expresión de los alelos recesivos son enmascarados o escondidos por el alelo dominante. Es decir, que si ambos alelos se encuentran juntos en un heterocigota, solo el alelo dominante se expresará.
Entonces el alelo dominante expresa la característica que resulta dominante, mientras que el alelo recesivo expresa la característica recesiva.
Genotipo:
Homocigota dominante ----> Expresa caracter dominante (Solo el alelo dominante esta presente)Heterocigota -------------------> Expresa el caracter dominante (Ambos alelos estan presentes, pero el dominante es quien se expresa)Homocigota recesivo --------> Expresa el caracter recesivo (solo alelos recesivos estan presentes)Por ejemplo, si tenemos dos fenotipos rojo y amarillo, y sabemos que el color esta codificado por un gen dialelico llamado M. También supongamos que no sabemos qué alelo expresa qué color. Teniendo solo estos datos, no podemos decir si el rojo es el color dominante o si el amarillo lo es.
Sin embargo, si tenemos los siguientes genotipos acompañando esta información:
MM--> AmarilloMm--> Amarillomm --> RojoRecién ahora podemos deducir que el caracter dominante es el amarillo.

What would occur to the amino acid sequence if the following mutation (G --> C in bold below) were to take place?
DNA sequence 3' TAC GGG ACT CTT TCC ACT 5'
What type of mutation is this?
Explanation:
TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
Can't see the bold :/
Insertion mutation I believe.
A codon chart can be used to read the genetic code. To utilize this chart, start by finding the first codon nucleotide, then the second, and finally the third. The chart will then show which codon codes for the amino acid. Because the genetic code is degenerate, there are several codons for each amino acid.
What role of genetic code in DNA sequence?The genetic code serves as the body's language for converting the DNA instructions from our genes into the constituent parts of life. It is typically discussed using the “codons” found in mRNA since mRNA is the messenger that transmits information from the DNA to the site of protein production.
Therefore, TAC GGG AGT CTT TCC ACT -DNA
AUG CCC UCA GAA AGG UGA -mRNA
Met Pro Ser Glu Arg Stop -Amino acid sequence
Insertion mutation.

Answer:
Touch is, in several ways, seemingly different from these other senses, however. For one thing, touch does not seem to have a single sense organ. ... Instead, the skin contains many different sensory systems. Many of them, like those that code for pain and itch, do not seem to be tied directly to the sense of touch.

DNA is created by the DNA polymerase and unzipped by the DNA helicase.
What is DNA?DNA stands for deoxyribonucleic acid.
DNA is defined as a collection of molecules that are in charge of transporting and passing genetic information from parents to children.
It can also be defined as a sophisticated molecule that carries all the data required to create and maintain a creature.
There are basically two types of DNA.
Autosomal DNAMitochondrial DNAToday, DNA serves three unique purposes: genetic, immunological, and structural, all of which depend in different ways on the sugar phosphate backbone and the bases.
Replication, information encoding, mutation/recombination, and gene expression are the four functions that DNA performs.

Read the following summary, which describes blood flow and heart output in space. Then, answer the question.
The heart doesn't have to do as much work to pump blood when in orbit. After only one day beyond Earth's gravity, astronauts have a lower blood volume. They can lose as much as 20 percent of their blood volume while on a space mission. Since the body has less blood to push around and the heart is pushing more blood with each beat, an astronaut's heart rate also slows down to compensate.

A carrier mother (XHXh) of hemophilia marries a normal father(XHY). *Use allele letter H What are the mothers and fathers genotype?
Answer: The mother of the man can be either XHXH or XHXh and pass her normal allele to the son and his father can be either XHY or XhY, he only passes his Y chromosome. The mother of the woman can be XHXH or XHXh and the father could be XhY, then she could have inherited the normal allele from the mother and the affected allele from the father. But also, the mother of the woman could be XHXh or XhXh and the father could be XHY, so in this case she could have inherited the normal alele from the father and the affected allele from the mother.
Explanation:
Hemophilia is an inherited bleeding disorder in which the blood does not clot properly. This can cause bleeding either spontaneously or after an injury.
It is related to the X chromosome and it is recessive for females, this mean they need both affected alleles to develop the trait. Males only need one recessive allele because they only have one X chromosome. This means that females need both parents to be at least carriers (although one or both can also have the disease or both recessive alleles). While males inherit it only from the mother, either she is a carrier (one recessive allele) or she has the disease (both recessive alleles). Then the mother passes the X chromosome with the affected allele to the son, and that son only receives the Y chromosome from the father, which does not have the gene that determines this disease.
If the mother is a carrier, her genotype is XHXh, being XH the normal allele and Xh the affected allele. She does not have hemophilia because she has a dominant allele. The father is XHY, so he does not have the disease because his only allele is normal (dominant)
The mother of the man can be either XHXH (she can only pass a normal allele) or XHXh and pass her normal allele to the son (in this case, the recessive allele is not inherited by chance.) His father can be either XHY or XhY, he only passes his Y chromosome which is not related to the disease. The mother of the woman can be XHXH or XHXh and the father could be XhY, then she could have inherited the normal allele from the mother and the affected allele from the father. But also, the mother of the woman could be XHXh or XhXh and the father could be XHY, so in this case she could have inherited the normal alele from the father and the affected allele from the mother.

Guard cells are found in plants and white blood cells are found in animals.
What are guard cells?Guard cells are specialised plant cells that regulate gas exchange in the epidermis of leaves, stems, and other organs. They are created in pairs, with a stomatal orifice separating them. What are white blood cells?The immune system's white blood cells, also known as leukocytes or leucocytes, are responsible for defending the body against both infectious diseases and foreign invaders. All white blood cells are created and developed from hematopoietic stem cells, which are multipotent cells found in the bone marrow. All parts of the body, including the blood and lymphatic system, include leukocytes.Guard cells function to allow gaseous exchange and white blood cells are responsible for the functioning of the immune system.

release carbohydrates
The oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
What is the significance of respiration and photosynthesis?The photosynthetic process is the one that can make oxygen as a product, and later that oxygen is used by plants and other animals in the process of respiration, which is essential for life as the cell makes energy in this process. Plants and other chloroplast-containing photosynthetic organisms, such as blue-green algae, phytoplanktons, etc., can produce oxygen, which is then used in respiration to power the cell's activities.
Hence, the oxygen and carbon dioxide exchange that occurs during photosynthesis and respiration aid in the release of carbon dioxide and the utilization of oxygen produced by the photosynthetic process.
