A. A glucose molecule
B. An mRNA molecule
C. A protein
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.

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
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.

Explanation:
It could be that both the parents were heterozygous, meaning having a dominant and recessive allele for example Aa..after these are paired you would see that they will form a white fur offspring.
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.
How can a mutation get into a population?
Answer:
Some mutations do not result in changes in the amino acid sequence of the encoded protein and can be described as silent mutations. Other mutations result in abnormal protein products. Mutations can introduce new alleles into a population of organisms and increase the population's genetic variation.

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".
[tex]{\sf{\boxed{\boxed{\tt\green{Las \: ventajas}}}}}[/tex]
La gran cantidad de ventajas que trajo el bipedalismo significó que todas las futuras especies de homínidos llevarían este rasgo. El bipedalismo permitió a los homínidos liberar completamente sus brazos, lo que les permitió hacerEnglish:

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.
Amoebas make exact copies of themselves. Therefore, they reproduce
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
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.

Why do identical twins have some DIFFERENCES?
A. The same genes are expressed because of their environment.
B. Different genes are expressed due to their environment.
C. Their DNA is different.
Answer:
B. Different genes are expressed due to their environment.
Explanation:
I think it's this one because it makes the most sense, but I'm still not sure sorry
Answer:
B. Different genes are expressed due to their environment.
Explanation:
Some identical twins can have different heights and weights. This is because height and weight are controlled by what you eat as well your DNA. Differences in diet can start earlier than you might imagine. When the twins are growing inside the uterus, there can be differences in how well they connect to the placenta.

Without knowing the genetic differences of the birds, how can we know that cardinals and finches are likely more closely related to each other than cardinals and finches are to woodpeckers? Cardinals and finches live in more similar habitats. There is no difference in their relatedness; because they are all birds, they all evolved at the same time from a common ancestor. Cardinals and finches have more morphological similarities. Fossil records show that cardinals have been around longer than woodpeckers and sparrows.
Answer:
The correct answer is - Cardinals and finches have more morphological similarities.
Explanation:
To find out the relatedness of the different species or organisms one can use genetic mapping to find precise relatedness, however, if one can not find the genetic differences of the organism one can use the morphological similarities and differences to find out how closely they are related.
Homologous structures and analogous structures are two major morphological characters to find how closely related cardinals and finches are than cardinals and finches are to woodpeckers.

Which of the following does NOT affect the flow of groundwater through an aquifer ? a. porosity C. gradient b . chemical weatheringd. permeability
Answer:
b . chemical weathering
Explanation:
Chemical weathering is not affected the flow of groundwater through an aquifer but affect by the porosity and permeability. The rate of groundwater flow is controlled by two properties of the rock which are porosity and permeability. Porosity is the percentage of void space in a rock while on the other hand, Permeability is the quality of being permeable means able to be penetrated or passed through by a liquid or gas.
