What kind of letter is used to represent a recessive allele?
A. Capital
B. Lowercase
Answer:
is B) lowercase
Recessive alleles are denoted by a lowercase letter (a versus A). Only individuals with an aa genotype will express a recessive trait; therefore, offspring must receive one recessive allele from each parent to exhibit a recessive trait.

Trastorno alimenticio caracterizado por una gran pérdida de peso, que el propio paciente se provoca y que puede conducir a un estado de inanición.
Answer: Anorexia nerviosa.
Explanation:
La anorexia nerviosa es un trastorno o desorden alimenticio en donde se produce un rechazo de la comida debido a un temor excesivo a subir de peso, llegando a un estado de inanición serio. Entonces, se produce un deterioro en la salud y una debilidad causada por una ingesta insuficiente de nutrientes causando una desnutrición que altera diversas funciones del organismo. Es mas común en mujeres jóvenes o adolescentes aunque se reportan casos en ambos sexos y a cualquier edad. No debe confundirse con otro trastorno llamado simplemente anorexia, que es un síntoma que se caracteriza por una falta de apetito debido a alguna causa orgánica.
Este trastorno puede ocurrir por diversas causas que vienen acompañadas por una distorsión de la imagen corporal propia, en donde la persona considera que debe perder más peso de lo que se considera saludable y normal para su edad y estatura, llegando a estados raquíticos. También hay muchos casos en donde además de una dieta extrema, se realice ejercicio de manera excesiva o que utilicen otros métodos para bajar de peso como el abuso de laxantes u otros medicamentos.
Algunos factores de riesgo para el desarrollo de la anorexia nerviosa pueden ser:
Personalidad perfeccionistaImagen propia negativa o baja autoestimaPresiones socialesPadecer algún trastorno de ansiedadAnyone know the answer?

How do mutations and the genetic
reshuffling that occurs during sexual reproduction benefit an organism? Select one:
They reduce the chances the organism will develop lethal diseases.
They cause loss of useless traits from the entire population.
They can make the organism better suited to the environment
They prevent the offspring from becoming prey for predators.
Answer:
they can make the organism better suited to the environment.
Explanation:
often when an organisms environment changes, the organism will change with it in order to survive...it's the survival of the fittest theory...you either adapt to your changing environment or the species will die off. this is shown in the way that different species of birds have differently shaped beaks based on the types of seeds and flowers available for them to eat. some eat big seeds and some eat small ones ...the humming bird has a certain flower it collects nectar from as food....when the flower gets larger, making the near further down and harder to reach, the humming birds beak will become slightly longer over a few generations making the better equipped to reach the nectar again ....

What happens during interphase? (Check all that apply)
A. General Cell Processes
B. Growth
C. DNA Replication
D. Mitosis
Answer:
A. General Cell Processes
B. Growth
C. DNA Replication
Explanation:
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells.
During interphase, the cell grows and makes a copy of its DNA. During the mitotic (M) phase, the cell separates its DNA into two sets and divides its cytoplasm, forming two new cells. So, the option A, B and C are correct.
What do you mean by interphase?Interphase is the portion of the cell cycle that is not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA and prepares for mitosis.
A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
Interphase is the longest part of the cell cycle. This is when the cell grows and copies its DNA before moving into mitosis. During mitosis, chromosomes will align, separate, and move into new daughter cells.

How are environment and development interrelated?
explain in brief.
How does polyploidy allow speciation to occur in a single generation? Polyploid offspring produce gametes earlier in the mating season than than their diploid parents, causing reproductive isolation between the two generations. Polyploid offspring produce smaller gametes that disperse farther than the gametes of diploid parents, causing geographic isolation between the two generations. Physiological differences between polyploid offspring and their diploid parents allow them to thrive in different environments, causing geographic isolation between the two generations. Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Answer:
Genomic differences between polyploid offspring and their diploid parents prevent them from successfully interbreeding, causing reproductive isolation between the two generations.
Explanation:
Speciation is an ecological and biological process through which new species are formed due to isolation.
In plants, polypoidy involves the possession of two complete sets of chromosomes and it leads to the origin of new species. Also, the two sets of chromosomes comprises of triploidy (69 chromosomes) and tetraploidy (92 chromosomes).
As a result of the genomic differences between polyploid offspring and their diploid parents, this usually prevent them from successfully interbreeding and consequently causing reproductive isolation between the two generations.
