If you could genetically engineer any species of organism, what would it be? Would it be a unicorn? A
dog-cat hybrid? Your own personal pet giant? Choose any species--real or not--that your imagination
desires!
Write a paragraph describing your species, what it looks like, and where it lives. Think of any inherited
traits the species has that might help it survive in its environment. Thinking of these traits now can help
you come up with allele combinations in the next step. Now describe your species in the answer space.
Answer:
the species I would combine would be a trapdoor spider and a eel yeah its a unusual mix but at the same time it would be interesting to see because image a eel having 8 legs and spider fangs and armored skin it would most likely also be twice the size of a normal eel or even might have a mutation but who knows

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
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.

Explanation:
sun is the biggest source of heat energy
electric heater is also an example of heat energy as it warms us
1. A cup of fresh coffee is very hot because the water particles are vibrating very rapidly giving the coffee heat energy.
2. A fire is a chemical reaction that is releasing energy as bonds are being broken, this energy is felt as warm or hot and is a release of heat energy.
The picture below represents which
stage of photosynthesis?
A. Dark reactions
B. Calvin Cycle
C Glycolysis
D Light reactions
It represents Glycolysis, a key metabolic route that produces energy and generates precursors for the production of primary metabolites in plants. Thus, option (C) is correct.
Green plants and certain other organisms convert light energy into chemical energy through a process called photosynthesis. Light energy is gathered and utilised during photosynthesis in green plants to change water, carbon dioxide, and minerals into oxygen- and energy-rich organic molecules.
The first method of breaking down glucose to release free energy is called glycolysis .Two molecules of pyruvate, two molecules of ATP, two molecules of NADH, and two molecules of water are produced during glycolysis.
Hence, the picture depicts the process of gylcolysis , stage of photosynthesis i.e option (c)

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
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.

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

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