Biology help A grown tiger began its life as a single fertilized egg. Explain why a tiger looks so much different as an adult than it did as a single fertilized egg.
Answers
A fertilized egg or zygote occurs just after the gamete union happened, at that moment the ploidy of the organism is restored, genetically all the genes are on, this means all are active and at that moment it will start cellular multiplication, now each cellular layer will start to differentiate by turning off certain genes, and genes like Hoax genes will start to guide the body plains, meanwhile in an adult animal no just tigers we have that the full-body plane has been already developed and each cellular line has been differentiated, DNA in every cell is methylated as differentiation already occurred, so even when genetically speaking of DNA the sequence is the same in the zygote as the adult tigger the DNA methylation pattern is totally different, without considering the total biomass increase directed by gene expressions.
when a sperm and an ovum fuse, a one-celled __________ is formed.
Answers
When a sperm and an ovum fuse, a one-celled Zyogte is formed. zygote, the fertilised egg cell produced when a female gamete (egg, or ovum) and a male gamete combine (sperm).
The zygote stage is brief and is followed by cleavage, when the single cell divides into smaller cells, in the embryonic development of humans and other animals. The zygote is the embryonic stage at which a genetically distinct organism emerges. The zygote is diploid because it contains genes from both parents (carrying two sets of chromosomes).
All organisms, with the exception of bacteria, reproduce sexually, and a common characteristic of this process is the combining of haploid gametes to create a diploid zygote.

Answers
The rain shadow is the dry slope of a mountain that is protected from predominant winds and rains. Usually, it is characterized by desertic conditions. The statement is false.
What is the rain shadow?A rain shadow is a meteorological event that occurs when dense clouds, driven by predominant winds, meet one side of a mountain. Rain occurs on this side, while the other side of the mountains remains dry.
The rain shadow is the dry slope of the mountain, which is protected from predominant winds in mountain chains. When referring to predominant winds, we mean the direction of winds that occurs more often in the affected region.
Usually, rain shadows are associated with desertic regions, because only dry winds reach these areas. Poor vegetation inhabits there.
According to this framework, the statmente is FALSE.

you must generate two examples below that make sense.
Answers
The statement that perceiving a stimulus involves perfectly transducing the stimulus from its form in the real world into an identical representation in the brain/mind is not entirely true.
Perception can be influenced by attention and selective processing. Our brain selectively processes incoming sensory information based on what we choose to focus our attention on. For example, when we are in a noisy environment, we can selectively attend to a specific conversation, while ignoring other conversations.
Perception can be influenced by the interpretation of the brain. Our brain uses prior knowledge, experiences, and expectations to interpret incoming sensory information. This means that the same stimulus can be perceived differently by different individuals. For example, a person who is afraid of dogs may perceive a barking dog as threatening, while a person who loves dogs may perceive the same dog as friendly.

Splicing is a procedure used to eliminate introns from the RNA molecule since they are not nitrogenous base sequences that can contribute to the creation of proteins. When the introns have been eliminated, the mRNA is prepared for exportation, which involves moving it from the nucleus to the cytoplasm. When the mRNA reaches the cytoplasm, it works with the tRNA, ribosomes, and other molecules to produce a polypeptide chain through a process known as translation, which converts nitrogenous bases into amino acids.The amino acids of the polypeptide chain are arranged in a straight line.

En el hombre el color negro de los ojos “A” domina sobre el color azul “a” Una pareja en la que el hombre tiene los ojos negros y la mujer ojos azules tienen dos hijos, uno de ellos de ojos negros y el otro de ojos azules. Averiguar:
a) El genotipo del padre.
b) Realizar el cruzamiento.
c) Porcentaje genotípico de los hijos.
Answers
El enunciado hace referencia a un caso de herencia monogénica y dominancia completa para el rasgo 'color de ojos', donde el padre es heterocigota y la madre es homo-cigota recesivo.
Las respuestas a estas preguntas son:
a) Genotipo del padre: Aa (ojos negros)
b) Cruzamiento: Aa (padre) x aa (madre)
c) Frecuencias genotípicas esperadas: 1/2 Aa; 1/2 aa
En genética, dominancia completa se refiere al proceso de herencia en la cual un individuo heterocigota, es decir, el individuo que presenta dos alelos diferentes para el mismo gen, presenta el mismo fenotipo que un individuo homo-cigota para el alelo dominante (el alelo dominante es aquel que enmascara la expresión del alelo recesivo en individuos heterocigotas).
En este caso, el carácter 'color de ojos' presenta un patrón de herencia monogénica, donde el alelo 'A' dominante codifica para el rasgo fenotípico ojos negros, mientras que el alelo 'a' recesivo codifica para el rasgo fenotípico ojos azules.
En el ejemplo, la pareja tuvo progenie en la cual uno de los hijos presenta el rasgo recesivo ojos claros, y por lo tanto el padre debe ser heterocigota y poseer un alelo recesivo 'a'; mientras que la madre expresa el fenotipo recesivo y por lo tanto su genotipo es 'aa'. En consecuencia, el cruzamiento de un padre heterozigota 'Aa' con una madre homo-cigota recesivo 'aa' producirá una descendencia con una frecuencia genotípica esperada de 1/2 (50%) de hijos con ojos 'color negro' de genotipo Aa y 1/2 (50%) de hijos con ojos 'color celelste' de genotipo aa >>
Cruzamiento: Aa (padre) x aa (madre)
Gametos padre: 1/2 A; 1/2 a
Gametos madre: 100% a
Cuadro de Punett (combinaciones gaméticas):

. Over what proportion of the earth’s history were there only single-celled living organisms? ______
Answers
The proportion of Earth's history that was dominated by only single-celled living organisms is 3 billion years.
The proportion of Earth's history during which only single-celled living organisms existed is vast. Single-celled organisms, such as bacteria and archaea, dominated the planet for the majority of its history. They first emerged around 3.5 to 3.8 billion years ago, shortly after the formation of the oceans and the stabilization of the early Earth's conditions.
For billions of years, these simple, unicellular life forms thrived and diversified in various environments. It was not until approximately 600 million years ago that complex multicellular organisms, such as algae and simple animals, began to appear in the fossil record.
This marked the transition from the exclusive reign of single-celled life to the emergence of multicellular organisms.
Considering that the Earth is estimated to be around 4.5 billion years old, single-celled organisms dominated for roughly 3 billion years or more, representing the vast majority of Earth's history.
Their evolutionary success and impact on shaping the planet were instrumental in laying the foundation for the complex ecosystems and diverse life forms we see today.

F- Explain the global carbon-climate cycle during the Cretaceous period. (Write only one paragraph describing what happened during the Cretaceous geological period in order to have good source rocks.)
Answers
During the Cretaceous period, high temperatures and abundant vegetation resulted in increased \(CO_2\) levels, leading to the accumulation of organic matter and the formation of good source rocks for oil and gas.
During the Cretaceous period, spanning from approximately 145 to 66 million years ago, the global carbon-climate cycle played a crucial role in the development of favorable conditions for the formation of good source rocks. The period was characterized by high global temperatures and abundant vegetation, resulting in increased carbon dioxide \((CO_2)\) levels in the atmosphere.
The elevated \(CO_2\) levels fueled vigorous photosynthesis, leading to the accumulation of organic matter in marine and terrestrial ecosystems. As this organic matter was buried and subjected to heat and pressure over millions of years, it transformed into oil and gas, creating potential source rocks. The warm climate and prolific vegetation during the Cretaceous, along with the subsequent geological processes, contributed to the formation of the rich hydrocarbon reserves that are vital to our energy resources today.
