qué ventajas le trajo al ser humano el poder andar en 2 patas.

Answers

Answer:

The advantage that hominids had when they developed bipedalism is truly great. Walking on two legs instead of four allowed hominids to free up their arms. Using their arms they could now make tools, stretch trees, and use their hands for social communication. The development of bipedalism also allowed for long-distance walking and eventually endurance running. Bipedalism, basically, was a key step for hominids' "brains to grow".

Which organism, roadrunner or the owl, competes more for its food?
Support your answer with evidence from the food web.

Answers

The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.

What do you mean by predators ?

Predators are animals that hunt, kill, and consume other animals (known as prey) for their sustenance. Predation is a common form of interaction between different species in many ecosystems. Predators come in many different forms, such as mammals, birds, fish, insects, and reptiles.

Predators are typically characterized by certain physical and behavioral adaptations that help them hunt and capture prey. For example, many predators have sharp teeth, claws, or beaks that are used to kill and consume their prey. Others may have specialized hunting techniques or strategies that make them highly effective predators.

The roadrunner and the owl are both predators and compete for similar prey, such as small mammals, birds, reptiles, and insects. However, the extent to which they compete for food depends on various factors such as their habitat, size, behavior, and hunting techniques.

Roadrunners are known to be opportunistic hunters and can feed on a wide range of prey items. They are ground-dwelling birds and use their speed and agility to catch their prey. Roadrunners are also known to eat eggs and young of other birds, including owls.

Owls, on the other hand, are nocturnal predators that are known for their exceptional hearing and vision, which enables them to hunt in low light conditions. They are also skilled hunters and can catch a variety of prey, including rodents, small mammals, and birds.

Therefore, both roadrunners and owls are capable of competing for food, but the level of competition depends on the availability of prey, habitat, and other factors. In general, the competition between these two species is likely to be limited, as roadrunners are diurnal (active during the day) and owls are nocturnal (active at night).

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend less time?
A. Interphase
B. R phase
C. M phase
O
D. Prophase

Answers

The cell spends less time in the M phase, also known as the mitotic phase, where the actual division of the cell takes place.

What does happen during M phase?

During this phase, the cell undergoes mitosis or meiosis, depending on the type of cell, resulting in the formation of two daughter cells. In contrast, the interphase is the longest phase of the cell cycle, where the cell grows and carries out its normal metabolic activities.

The R phase, also known as the S phase, is a sub-phase of interphase where DNA replication occurs. Prophase is the first phase of mitosis and is relatively short compared to the M phase as a whole.

During prophase, the chromosomes condense, the nuclear envelope breaks down, and the spindle fibers form. In metaphase, the chromosomes align at the metaphase plate.

During anaphase, the sister chromatids separate and move towards the opposite poles. Finally, during telophase, the spindle fibers disassemble, the nuclear envelope reforms, and cytokinesis occurs, resulting in the division of the cytoplasm and formation of two identical daughter cells.

In terms of the amount of time spent in each phase, interphase is the longest, accounting for about 90% of the cell cycle. M phase, on the other hand, is relatively short, accounting for only about 10% of the cell cycle. Therefore, a cell spends less time in M phase than in interphase.

O B. Some iguanas are better swimmers than others.

O C. The species arrived on the islands in different ways.

OD. The species adapted to each island's unique habitat.

Answers

OD because they acquired adapted traits to better suit them in their environment

The statement that explains each island in the Galapagos has unique kinds of iguanas is that the species adapted to each island's unique habitat. The correct option is D.

What is adaptation?

Adaptation is defined in biology as a heritable behavioral, morphological, or physiological trait that has evolved through natural selection and maintains or increases an organism's fitness under a given set of environmental conditions.

To survive, all organisms must adapt to their surroundings. This entails adapting to the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space.

The marine iguana is the only lizard in the world that can live and forage at sea, and it is only found in the Galapagos Islands.

There are eleven very similar subspecies found on various islands, with Isabela and Fernandina having the most. The species adapted to the distinct habitats of each island.

Thus, the correct option is D.

Many of the D-amino acids found in nature have been discovered in bacterially produced peptides that have antibiotic properties. Bacteria secrete these peptides into their environments to kill competitor bacteria and thereby gain a selective advantage. Given your answer to part (a) of this question, what potential advantages might D-amino acids confer to a secreted peptide toxin

Answers

Answer: D-amino acids are less likely to be recognized by proteolytic enzymes thereby they are not degradated.

Explanation:

Peptides are a type of polymers formed by joining several amino acids by means of peptide bonds. They are responsible for a large number of important cellular functions for the organism. Amino acids are thus the monomers that make up peptides and consist of an amino group (-NH2) at one end of the molecule and a carboxyl group (-COOH) at the other end.

Antibiotics are chemical substances produced by a living being (although they can also be synthetic derivatives made in laboratories), which kill or prevent the growth of certain kinds of sensitive microorganisms and are generally drugs used in the treatment of bacterial infections.

All amino acids, except glycine, are stereoisomers which means that there are nonoverlapping mirror images of their structure. These are labeled L (left-handed) and D (right-handed) to distinguish mirror images. A mirror image, for example, compares a right foot with a left foot. They are similar, but not exactly the same, they are like mirror images of each other. However, we could not, for example, put a right shoe on a left foot and vice versa. The same analogy applies to stereoisomers, they are similar but not superimposable, which means that not all compounds will act in the same way in an L or D molecule. For some reason, the amino acids that make up the proteins in human bodies are all L-amino acids.

To distinguish an L-amino acid from a D-amino acid, we must look at the α-carbon, which has four substituents forming a tetrahedron. then we must identify the hydrogen bonded directly to this carbon. In this way they are numbered and following the numbering order, they are classified as L or D.

Bacteria that secrete D amino acids kill other bacteria in the environment that might compete with them for resources, because they have antibiotic properties. These D amino acids are not usually recognized by proteolytic enzymes in organisms that degrade peptides or proteins. So the amino acid remains in the environment fulfilling its function, which is an antibiotic function to fight against other bacteria. Peptide toxins also fulfill this function, however, if they are destroyed by proteases.

El pelaje negro de los borregos se debe a un alelo recesivo n frente a su alelo N que determina el pelaje blanco. Si cruzamos un individuo homocigótico blanco con un homocigótico negro, ¿de qué color serán los descendientes de la primera generación filial? GENOTIPO-FENOTIPO

Answers

Answer: Los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.

Explanation:

Un gen es un segmento de ADN que codifica para una proteína. Para cada gen, hay distintas versiones, conocidos como alelos. Por ejemplo, el gen que codifica para el pelaje tiene los alelos para el color blanco y para el color negro. Considerando que los organismos diploides tienen dos copias de cada gen (dos alelos), un alelo dominante solo necesita una copia para expresarse. Mientras que un alelo recesivo, necesita dos copias.

En este ejemplo, el borrego homocigota blanco tiene un genotipo (conjunto de genes) de AA ya que el color blanco es dominante y al ser homocigota indica que ambos alelos son iguales. El borrego homocigota negro tiene un genotipo de aa ya que se necesitan dos alelos recesivos para mostrar ese fenotipo (características visibles).

Los borregos producen gametos, los cuales son células sexuales (espermatozoide u óvulo) haploides, es decir que solo poseen un alelo de cada gen. Entonces el borrego AA solo produce gametos con genotipo A, mientras que el borrego aa solo produce gametos con genotipo a. Estos gametos son los que se cruzan, es decir que la descendencia solo puede tener un genotipo Aa (con un alelo de cada padre)

El genotipo Aa posee un alelo dominante A (que codifica para el color blanco) que enmascara los efectos de el alelo recesivo a (que codificaría para el color negro) Entonces, los descendientes de la primera generación filial tendrán un genotipo Aa y un fenotipo color blanco.
