A Three-leaf clover is dominant (T) to four leaves (t). What is the probability of an offspring having 4 leaves when you cross a heterozygous clover with a four-leaf clover?
O 25%
O 50%
O 75%
O 0%
Answers
Answer:
%50
Explanation:
Heterozygous = 2 different alleles (Tt)
4 leaf clover = 2 recessive alleles (tt)
T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves
For a recessive trait (four leaves) to show 2 recessive alleles are needed
To find the percentage of the offspring to have four leaves a punnet square should be created
To find the percentage divide the number of four leaf offering with 4 and multiply by 100
2÷4×100=50
= 50%

8. The graph below shows the reaction rates of two different reactions. Which of the following statements could explain the difference in the two reactions?
Answers
Answer:
These two reactions have different reactants, bonding and catalysts.
Explanation:
The two reactions are different from one another due to fusion of different reactants as well as different products. These two reactions may have different types bonding i.e. covalent, ionic or metallic bond etc between their atoms.

at what point did the climate began to fluctuate more severely ? (2 points )
Answers
Answer:
Due to greenhouse gases.
Explanation:
When the high emission of greenhouse gases occurs, the climate began to fluctuate more severely because greenhouse gases such as carbondioxide gas and methane etc block the solar radiation that is reflected back to space which is responsible for the change of climate. If there is more greenhouse gases are emitted in the atmosphere so there is more fluctuation in the climatic condition of earth atmosphere so we can conclude that greenhouse gases leads to fluctuation of climatic conditions more severely..

Resuelve el problema relacionado con las etapas del ciclo menstrual: "Si el día fértil de la polola de Luciano es el 09 de noviembre y ella tiene un ciclo de 28 días ¿ Cómo puede calcular el primer día de menstruación de su polola en ese mes y el período fértil? En la respuesta debes registrar: Primer día de menstruación, Día de ovulación y período fértil.
Answers
Answer: El primer día de la menstruación comenzaría el 26 de octubre y el período fértil es desde el 6 de noviembre hasta el día 9 (fecha de ovulación)
Explanation:
El ciclo menstrual está compuesto por cuatro fases: menstruación, fase folicular, ovulación y fase lútea.
Menstruación: Eliminación del revestimiento engrosado del útero (endometrio) del cuerpo a través de la vagina. El flujo menstrual contiene sangre, células del revestimiento del útero (células endometriales) y moco. La duración media de un periodo es de entre tres días y una semana.Fase folicular: Comienza con la menstruación y termina con la ovulación. La glándula pituitaria libera la hormona estimulante del folículo (FSH), estimulada por parte del hipotálamo. Esta hormona estimula al ovario para que produzca entre cinco y 20 folículos (nódulos o quistes diminutos), que se acumulan en la superficie. Durante la fase folicular, el folículo en desarrollo provoca un aumento del nivel de estrógenos. El hipotálamo, en el cerebro, reconoce este aumento y libera una sustancia química llamada hormona liberadora de gonadotrofina (GnRH). Esta hormona hace que la hipófisis produzca niveles elevados de hormona luteinizante (LH) y FSH. En el plazo de dos días, los altos niveles de LH desencadenan la ovulación. Ovulación: El óvulo es conducido hacia la trompa de Falopio y hacia el útero por medio de ondas de pequeñas proyecciones similares a pelos. La vida del óvulo típico es de sólo unas 24 horas. A menos que se encuentre con un espermatozoide durante este tiempo, morirá. Entonces, la ovulación consiste en la liberación de un óvulo maduro desde la superficie del ovario. Suele producirse en la mitad del ciclo, unas dos semanas antes de que comience la menstruación.Fase lútea: Durante la ovulación, el óvulo se desprende de su folículo, pero el folículo roto permanece en la superficie del ovario. Durante las dos semanas siguientes, aproximadamente, el folículo se transforma en una estructura conocida como cuerpo lúteo. Esta estructura secreta progesterona y estrógeno. Esta combinación de hormonas mantiene el revestimiento del útero engrosado, a la espera de que se adhiera un óvulo fecundado (implante). Si el óvulo fecundado se implanta en el revestimiento del útero, éste produce las hormonas necesarias para mantener el cuerpo lúteo. Esto incluye la gonadotrofina coriónica humana (HCG), la hormona que se detecta en un análisis de orina para detectar un embarazo. El cuerpo lúteo sigue produciendo los niveles elevados de progesterona necesarios para mantener el grosor del revestimiento del útero. Si no se produce el embarazo, el cuerpo lúteo se marchita y muere, normalmente alrededor del día 22 de un ciclo de 28 días. El descenso de los niveles de progesterona hace que el revestimiento del útero se desprenda (menstruación)La duración media del ciclo menstrual es de 28-29 días, pero puede variar entre las mujeres y de un ciclo a otro. La duración del ciclo menstrual se calcula desde el primer día de la menstruación hasta el día anterior al inicio de la siguiente.
Si consideramos que el primer día fértil es el 9 de noviembre y el ciclo es de 28 días, el primer día de la menstruación comenzaría el 26 de octubre y el período fértil es desde el 6 de noviembre hasta el día 9 (fecha de ovulación) Esto es porque la menstruación ocurre aproximadamente 14 días luego de la ovulación si el ciclo es de 28 días. Los días más fértiles son aproximadamente desde 3 días antes de la ovulación. Aunque en algunos casos, la fertilidad puede durar hasta dos días después de la ovulación.

A symbiotic relationship in which one species benefits and the other is harmed is known as mutualism. predation. commensalism. parasitism.
Answers
Answer:
Parasitism
Explanation:
Example: Mosquitoes feed off the blood of a human and is benefitted, the human is harmed because the mosquitoe exposed he/she to malaria.
A symbiotic relationship in which one species benefits and the other is harmed is called parasitism. The parasite lives on the food of the host. Fourth option is correct.
What are different types of symbiotic associations?In symbiosis, two organisms are present in close contact. There are different types of relationships seen in nature, such as mutualism, commensalism, parasitism, etc.
Mutualism occurs when two organisms, such as lichen, benefit from one another. Lichen is an association of algae and fungi. Algae makes food that is consumed by fungi, and fungi provide algae for a place to live.
In parasitism, one is the host, and the other is the parasite. An example is the tapeworm in the human intestine. Tape worms consume digested human food and harm humans by spreading their population. Here, the host is negatively impacted by the presence of parasites.
In predation, both are harmed as both are involved in the fighting. In commensalism, one party gets benefits while the other is not harmed by the association.
Hence, the fourth option is the correct answer, which is parasitism.
