1.- Embrión se desarrolla dentro del sistema reproductor femenino.
2.- Formación de un organismo a partir de huevos
Answer:
1. Vivíparo
2. Ooviparismo
Explanation:
Viviparismo se define como el proceso de desarrollo de un animal en el cual el embrión crece dentro dentro del sistema reproductor femenino en una estructura acorde que le permite obtener alimento y oxígeno hasta su nacimiento. El viviparismo placentario es el tipo de desarrollo más extendido entre mamíferos (por ejemplo, perros, caballos, gatos, conejos, etc), a excepción de mamíferos que son ovíparos (por ejemplo, el ornitorrinco) y los mamíferos marsupiales que no poseen placenta y donde feto se desarrolla en una bolsa externa llamada marsupio (por ejemplo, los canguros). Por otra parte, el oviparismo es un mecanismo de desarrollo en el cual el embrión crece dentro de un huevo desde el momento que la hembra lo expulsa hacia el exterior. Cuando se produce este suceso, los embriones se encuentran muy poco desarrollados y por lo tanto deben cumplir su ciclo de crecimiento (hasta eclosionar del huevo) fuera del vientre materno. Algunos ejemplos de animales ovíparos incluyen anfibios, reptiles, aves, insectos, etc.

An amino acid analyzer is an instrument used to determine a. the sequence of amino acids in a polypeptide chain b. the presence of modified amino acids in a protein c. the identity of N-terminal and C-terminal amino acids in a protein d. the identities and relative amounts of amino acids in a protein
Answer:
d. the identities and relative amounts of amino acids in a protein
Explanation:
An amino acid analyzer is an automated machine that is used to determine the identities and quantities of amino acids in a given protein, peptide, and cellular samples. It makes use of the ion-exchange chromatography principle to determine the presence of amino acids. When the chromatogram is obtained, the relative amounts are then determined by the analyzer.
Since proteins are made of sequences of amino acids, the identities of proteins can also be obtained through this method. Ninhydrin, in the chromatographic column, reacts with the present amino acids under an ultra violet detector and is then observed at a wavelength of about 440 - 570nm.
If Darwin knew of Mendel's work, how might it have influenced his theory of evolution? Do you think this would have affected how well Darwin's work was accepted?
Answer:
See explanation
Explanation:
According to Darwin, the determinant of the ability of species to thrive in their environment is their ability to develop favourable characteristics which enable them to survive in their environment. This ability to develop favourable characteristics is called natural selection.
These favourable characteristics are passed on from parents to offsprings and are responsible for the perpetuation of organisms having these favourable characteristics in comparison to other members of the same species.
In relation to Mendel's theory, these favourable characteristics could be regarded as Mendel's factors (currently identified as genes). These factors are units of inheritance passed on from parents to offsprings.
If Darwin had an idea of Mendel's work when he propounded his evolution theory, he could have modified his idea of favourable characteristics to imply genes. This would have made his idea more empirical than speculative and led to a faster world wide acceptance of his ideas.

In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. In a well-fed human eating a Western diet, the richest source of stored chemical energy in the body is ________. glucose in the blood fat in tissue calcium phosphate in bone glycogen in muscle cells protein in muscle cells
Answer:
fat in tissue
Explanation:
Biomolecules like carbohydrates, fats etc. are well known for their energy storing abilities. Glucose, as a carbohydrate, is the most used source of energy but is stored in excess as glycogen in the muscle and liver cells.
However, fats are far more efficient in storing energy than carbohydrates or proteins because they give more ATP per molecule. Fats are stored in tissues of the body called ADIPOSE tissues. Hence, the richest source of stored chemical energy in the body is FATS IN TISSUES.
In what ways is a eukaryotic cell similar to a city?
Answer: In many ways, the eukaryotic cell is kind of like a city. I will tell you what each of the organelles in a cell does. Your job will be to try to match each of the cell parts to the parts of a city and explain why they are similar. a) Golgi Apparatus: packages up proteins and labels them for distribution to other parts of the cell.
Each one, like the organs inside your body, fulfills a particular function that is required for the cell to stay alive. Consider the cells to be a miniature city. Because they all do similar jobs, the organelles could represent companies, places, or parts of the city.
What is a cell?Cells are the fundamental building blocks of all life. Gazillions of cells make up the human body.
They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.
Each one, like the organs in your body, performs a specific function that is required for the cell to survive. Think of the cells as a miniature city.
Because cell city has jobs that a plant cell does not, it represents an animal cell. In cell city, we believe that a waste disposal plant performs the same function as lysosomes, an organelle found only in animal cells.
Thus, this way, a eukaryotic cell similar to a city.

What factor is described as sexual
selection?
A, non-random mating
B. migration
C. small populations
D. natural selection
Answer:
The correct answer is - D. natural selection.
Explanation:
Sexual selection takes place due to competition between individuals of the intraspecies same-sex and of mate choice which driving the evolution of reproductive traits.
Sexual selection is a mode of natural selection as it leads to the evolution of specific traits. Other examples or options are not related to sexual selection directly and are not affected by sexual selection.
Cell specialization is important during the growth and development of
a multicellular organism. This process is most directly regulated by
Answer:
Protein
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms.
Cell specialization is also referred to as cell differentiation and it can be defined as a biological process through which generic cells transform into specific cell types, so as to enable them perform certain functions within the body of a living organism.
Simply stated, it's the special function or job in the body of a living organism that are associated with cells.
Generally, cell specialization plays a significant role in the development of embryos.
Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell specialization is fundamental and key for the growth and development of a multicellular organism.
Furthermore, cell specialization as a process is most directly regulated by protein; one super regulating protein encourages cell differentiation while the other tries to stop or prevent the process. These proteins are referred to as master regulating proteins or Helix-Loop-Helix proteins.

Nitrogen is the most common element in the air. Why do bacteria play a role in the nitrogen cycle?
Explanation:
Bacteria play a role in the nitrogen cycle because:The bacteria’s helps in breaking down the organic materials which has nitrogen in it, and helps in giving the nitrogen back to the cycle. Bacteria helps in breaking down of the leaves and then it diffuses the nitrogen to the soil. Prokaryotes also plays an important role in the nitrogen cycle. The nitrogen fixing bacteria present in the root zone of plants basically in the soil, helps in conversion of the nitrogen into ammonia. Then the nitrifying bacteria converts the ammonia to the nitrites or can say nitrates.

Fruit trees in a forest are an important habitat for a bird species and were historically a major source of food for a rodent species. Over time, the rodent species shifted their feeding behavior from fruit trees to nut trees. As rodent behavior changed, the density of fruit trees decreased, which caused significant decreases to the bird population. What kind of effect did the change in rodents exert on bird population size?
Answer:
The bird population might have to migrate in search for food or may decline in numbers.
Explanation:
This is a concept of primary producers that is trees and secondary consumers that is mouse and bids. Due to the decline in raw material available the mouse population declines and this also affects the secondary consumers that are birds of prey like hawks, owls etc.what is photosynthesis
