Complete question:
Which of the following statements is NOT correct about the flatworms?
A. There are three complete tissue layers.
B. Flatworms may be either free-living or parasitic.
C. Flatworms have a sac body plan, with only a mouth and no anus.
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
E. Most planaria are found in marine environments, but some dwell in freshwater and moist terrestrial environments.
Answer:
D. Parasitic flatworms have a well-developed head with eyespots and nerves concentrated into a brain.
Explanation:
Flatworms are inferior organisms, meaning that they do not have nerves concentrated in a brain. Their nervous system is, in general, composed of nerve cords forming a net. The arrangement depends on each of the groups. They have one or more pairs of primitive eyes, which function is to find the light. These eyes cup-shaped and are composed of pigmentary cells.
Flatworms have bilateral symmetry. Their body is plane dorsoventrally and can be divided into two specular halves by the sagittal plane. This plane crosses through the body from the anterior extreme to the posterior extreme. The frontal plane divides the body into two different halves, the ventral one with the mouth and the dorsal one.
These organisms only have one opening in their bodies directed to the digestive system, which is the mouth.
Flatworms are aquatic and, most of them are marine animals, although there can be a few groups that inhabit freshwater. Some species might even be terrestrial. Most of them are free-living organisms, but there are also some parasitic forms.

The outcome of protein synthesis is ______.
A. A glucose molecule
B. An mRNA molecule
C. A protein
Answers
Answer:
C. A protein
Explanation:
The outcome of protein synthesis is a protein.
The process of protein synthesis is crucial to cellular function. Protein synthesis is the procedure used by cells to generate proteins. Thus, option C is correct.
What is the role of protein synthesis in the cell?Protein synthesis, sometimes referred to as protein biosynthesis, is an essential biological process that occurs inside of cells to replace lost proteins (due to export or degradation) with new proteins.
Proteins have a wide range of vital biological functions, including those as enzymes, hormones, and structural proteins.
Cells are made of proteins, and the word “synthesis” simply means “to make.” Thus, the process of producing proteins is known as protein synthesis.
Creating a polypeptide, or protein consisting of a chain of amino acids, is the sole goal of protein synthesis. Keratin, a protein, is produced in the cells of the hair follicle.
Therefore, The outcome of protein synthesis is a protein.

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".

A. asexually buy the process of MEIOSIS
B. sexually by the process of MITOSIS
C. sexually by the process of MEIOSIS
D. asexually by the process of MITOSIS
Answers
Answer:
D.
Explanation:
You can rule out B and C because offspring produced sexually are not identical to their parents. The amoebas reproduce by binary fission, which is a form of asexual mitosis.
Answer:
D. asexually by the process of MITOSIS
Explanation:
Mitosis is a form of asexual reproduction in simple living organisms. The outcome of each cell cycle is two identical cells. Mitotic checkpoints happen at certain stages of mitosis to ensure that each cell receives the same amount of DNA.

Explanation:
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.

Proteins secreted by Gram-negative cells face multiple obstacles, including _____. Multiple choice question. moving across the periplasmic space underlying the thick peptidoglycan layer of the cell wall moving across the plasma membrane moving across the plasma membrane and the thick peptidoglycan layer of the cell wall moving across both the plasma membrane and the outer membrane
Answers
Answer:
moving across both the plasma membrane and the outer membrane
Explanation:
Gram-negative bacteria are bacteria that have a plasma membrane, a thin peptidoglycan layer, and an outer membrane (the space between the plasma membrane and the outer membrane is known as periplasm). Moreover, Gram-positive bacteria exhibit neither outer membrane nor periplasmic space and are surrounded by thick layers of peptidoglycan. Gram-negative bacteria have developed different protein secretion systems (types I–VI and type VIII) in order to secrete proteins into the extracellular space. For such purpose, the XcpQ protein (which is an outer membrane protein from the secretin family) participates in different transport processes in Gram-negative bacteria.
