How are internal and external fertilization alike and different?

Answers

Answer 1
Internal fertilization is the process when the syngamy (union of male and female gamete) occurs inside the female body after insemination using copulation. In contrast, External fertilization is the syngamy outside the female body, that is in the outer environment especially in water bodies.
Answer 2

Answer:

Internal fertilization is the process when the syn-gamy "union of male and female gamete", occurs inside the female body after insemination using copulation. External fertilization is the syn-gamy outside the female body, that is in the outer environment especially in water bodies. Sorry if this is a late answer.

Explanation:

The main difference between organ and organelle is that organ is a large part of an organism, composed of tissues which perform similar functions whereas organelle is a specialized structure found inside cells, which carries out a specific life process. ...

Answers

Answer:

Darwin's theory its simple thus that do not evolve shall dissolve meaning if an organism cannot keep up with the environment around it it will die off and if it can it will evolve.

Explanation:being that there are many species of cat that prolly come from one organism they all evolved according to there needs

The idea of ​​evolution is one explanation for the similarities between living things and extinct ones, such as the Smilodon saber-toothed tiger and contemporary cats. Through the processes of natural selection, genetic drift, and gene flow, populations of species undergo evolution over time.

What is an Evolution?

Natural selection, genetic drift, and gene flow are three processes that allow populations of organisms to change over time. This process is known as evolution.

When populations of organisms diversify and some individuals have traits that are more beneficial to their environment than others, evolution occurs. This causes the evolution of new species over time that are more adapted to their surroundings.

For example, the evolution of modern cats from the Smilodon saber-toothed tiger probably occurred over a long period of time through a succession of small changes in the cat population. Eventually, the evolution of the contemporary cat was influenced by cats that had somewhat sharper teeth or a greater hunting ability because they were more successful at catching prey and passing on their genes.

Therefore, the idea of ​​evolution is one explanation for the similarities between living things and extinct ones, such as the Smilodon saber-toothed tiger and contemporary cats.

The Arecibo message and the beacon in the galaxy were broadcast in binary code because binary is a universal language that can be easily understood by any intelligent beings, regardless of their language or culture. Binary code consists of only two symbols, 0 and 1, which can be used to represent any information, including letters, numbers, and instructions. This makes binary an ideal choice for transmitting messages over vast distances, as it is less prone to errors and can be decoded with a high degree of accuracy.

Answers

A pedigree chart is used to track inherited traits through generations.

A pedigree chart is a visual tool that represents the inheritance patterns of specific traits or genetic conditions within a family. It helps to trace the occurrence of traits, diseases, or genetic conditions across multiple generations by depicting the relationships between individuals and their affected or unaffected status.

Pedigree charts are commonly used in genetics and genetic counseling to analyze patterns of inheritance, identify carriers of genetic disorders, determine the probability of passing on certain traits or diseases, and study the transmission of traits within families. By examining the patterns of inheritance in a pedigree chart, one can gain insights into the mode of inheritance, such as autosomal dominant, autosomal recessive, or X-linked inheritance, and make predictions about the likelihood of certain traits or conditions appearing in future generations.
