Answer:
sperm cells which are modified to perform fertilisationWhy is carbon so important for living things
Answer:
Organic compounds make up the cells and other structures of organisms and carry out life processes. Carbon is the main element in organic compounds, so carbon is essential to life on Earth. Without carbon, life as we know it could not exist.
Explanation:
Answer:
Carbon is the most important element to living things because it can form many different kinds of bonds and form essential compounds.

When a genotype of a guinea pig is "Hh" (select all that are true)
One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair
Both chromosomes in the homologous pair carry the genetic sequence to make hair
Answer:
One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair
Explanation:
Hairy is dominant over hairless. If there was a hairless guinea pig here instead, we would know its genotype. It would be hh. Remember any time a dominant allele is present it is expressed in the phenotype, so if the phenotype is not the dominant one, we know the genotype must contain two recessive alleles.
These are the factors that is true, When a genotype of a guinea pig is "Hh"
• One chromosome of the homologous pair has a sequence that results in hair and one chromosome has a sequence that results in no hair
• One copy of the "H" allele on the homologous chromosome is enough to make the guinea pig have hair since both alleles are transcribed and translated
• Only one of the chromosomes in the homologous pair carry the genetic sequence to make hair

How does bacteria cause disease?
Answer:
Bacteria cause disease by secreting or excreting toxins (as in botulism), by producing toxins internally, which are released when the bacteria disintegrate (as in typhoid), or by inducing sensitivity to their antigenic properties (as in tuberculosis).

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.

Comparing the four most common types of power plants in Alberta (coal, natural
gas, wind, and hydroelectric), which has the lowest efficiency in electricity
generation? and why?
Answer:
Coal.
Explanation:
Steam power plant has the lowest efficiency in electricity production which can only be run with the use of fossil fuels such as coal. The efficiency of this power plant is the lowest because large amount of coal is converted into smoke and other gases and very less amount of coal into heat energy. This coal is used to produce heat energy which can be used in the heating of water to produce steam. This steam is used to move turbines which turn mechanical energy into electric energy.

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:
