Answer:
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Explanation:
Lethargy in infants can be seen in several ways. one of this is that the child may be sluggish and as if he or she has little or no energy. the child may find it difficult to be awake for feeding. And can lose alertness and pays less attention to sounds and the baby is always drowsy. The registered nurse has to assess this baby immediately because lethargy could happen because the baby may have an infection or probably have low blood sugar. Therefore the last option is the best option for the nurse to take.

Geomorphology studies landforms and their evolution. Qualitatively, landforms have been described, and numerically, forces acting on Earth's surface to create landforms and change them. Therefore, it's false.
What is geomorphology?The scientific study of the formation and development of topographic and bathymetric features formed by physical, chemical, or biological processes occurring at or near the surface of the Earth is called geomorphology.
Geomorphic processes are those that alter the way the earth's surface is arranged and are responsible for the field of study known as geomorphology. Endogenic geomorphic processes include both continental drift and volcanic activity. The processes of mass wasting, weathering, erosion, and deposition fall under the category of exogenic geomorphic processes.

can mercury diffuse in our body using simple diffusion ?
Answer:
No,mercury can't diffuse in our body using simple diffusion.
Explanation:
It is only slowly absorbed through the skin, although it may cause skin and eye irritation. Elemental mercury droplets may be absorbed through eye contact. Ingestion is not an important route of acute exposure as almost no elemental mercury is absorbed through the gastrointestinal tract.

This Roman snail, this cuttlefish, and this mussel have similarities and differences in their body structures. What does the information about these structures tell you about the ancestors of these species
Complete question:
This Roman snail, this cuttlefish, and this mussel have similarities and
differences in their body structures. What does the information about these
structures tell you about the ancestors of these species?
a) None share an ancestor population because different species cannot share an ancestor population. It is a coincidence that these species have some of the same body structures.
b) The Roman snail and the cuttlefish share an ancestor population, but they must not share an ancestor with mussels because mussels have no radula.
c) All three species share an ancestor population, but Roman snails and
cuttlefish share a more recent ancestor population. This is why they share
the radula structure.
d) We cannot make observations of ancestor populations from the past. It is
impossible to explain ancestors with only the information about the body
structures of different species.
Answer:
The correct answer is option C. All three species share an ancestor population, but Roman snails and cuttlefish share a more recent ancestor population. This is why they share the radula structure.
Explanation:
The three species belong to the mollusk phylum, and to the placophore group.
Each of them belongs to a different class.
The Roman snail belongs to the Gasteropod class, The cuttlefish belongs to the Cephalopod class, The mussel belongs to the Bivalve class.The tree classes share a common ancestor from which all the placophores evolved. Among them, we can mention the monoplacophore, gasteropod, cephalopod, bivalve, and scaphopods. Three branches diverged from this common ancestor. The first one originated the monoplacophore. The second one originated the common ancestor of gastropods and cephalopods. And the third one originated the common ancestor of bivalves and scaphopods. The tree-mentioned species inherited the mantle and the radula from their foreign common ancestor. But later in time, individuals that originated bivalves lost the radulla. This is why the three species have a mantle, but only gastropods and cephalopods have a radula. When each of these classes evolved, they developed their own traits,
Gastropods → muscular foot used for moving Cephalopods → pallial cavity for swimmingBivalves → byssal threads to attach to the rocksYou will find an image in the attached files that will help you understand this explanation.
How do the process of DNA replication and the laws of inheritance help cells and individuals pass on their
traits?
DNA copying is otherwise known as DNA replication which is the process of producing 2 identical copies of DNA from one original DNA molecule during cell division. DNA copying is important because it generates variation during sexual reproduction which leads to evolution. Also, DNA copying helps in transfer of information or characters from the parents to the offsprings.
Mendel studied traits with only one mode of inheritance in pea plants. The inheritance of the traits he studied all followed the relatively simple pattern of dominant and recessive alleles for a single characteristic. There are several important modes of inheritance, discovered after Mendel’s work, that do not follow the dominant and recessive, single-gene model.

How do white blood cells protect the body against infections
Answer:
White blood cells, which are also called leukocytes or white corpuscles, are a cellular blood component that does not include hemoglobin, have a nucleus, are motile, and protect the body from infections and diseases through ingestion of foreign materials and cellular debris, destruction of infectious agents and cancer cells or production of antimicrobials.
Explanation:
There are 4,500 to 11,000 cells in the white blood of a healthy adult person per cubic mm of blood. During the day, fluctuations in the number of white cells take place; lower values during rest and higher during exercise are attained. The quantity of white cells increases abnormally, while the number decreases abnormally, Leukopenia.
Intensive physical activity, seizures, extreme emotional response, pain, pregnancy, labor, and specific conditions such as infections and intoxications may increase the counting of white cells. In reaction to some types of infections or medication, or in conjunction with certain illnesses such as chronic anemia, malnutrition, or allergy, the number may drop.

¿Cuál de las siguientes opciones son adaptaciones de las plantas al desierto? a) Las raíces superficiales y extensas. b) Las hojas de color amarillas c) El cuerpo carnoso de las plantas d) Las hojas modificadas en forma de espina
Answer:
a) Las raíces superficiales y extensas
c) El cuerpo carnoso de las plantas
d) Las hojas modificadas en forma de espina
Explanation:
En biología, una adaptación refiere al proceso de cambio evolutivo mediante el cual los organismos de una especie/taxón hacen frente a determinadas condiciones ambientales. Las plantas han desarrollado diferentes adaptaciones en ambientes desérticos a fin de evitar al máximo la pérdida de agua, el factor más limitante en este tipo de ambientes. Las plantas capaces de soportar largos periodos de sequías se denominan xerófitas. En primer lugar, además de servir como una buena defensa contra herbívoros, las hojas en forma de espina le permiten a una planta almacenar agua durante los períodos de precipitaciones. En segundo lugar, las raíces de plantas desérticas pueden disponerse superficialmente con el objetivo de absorber la mayor cantidad de agua posible. En tercer lugar, las plantas suculentas o crasas son aquellas que tienen tejidos carnosos los cuales pueden almacenar agua en sus hojas, tallos o raíces. Durante los periodos de lluvia leve, las suculentas almacenan grandes cantidades de agua para sobrevivir durante la temporada seca (incluso existen especies vegetales que sobreviven solamente durante la temporada húmeda y producen semillas que toleran la temporada seca).

Phylogenetic trees are not subject to change. Classification can change with new discoveries and evidence. Classification does not change with more evidence. Phylogenetic trees are inaccurate.Answer:
2. Classification can change with new discoveries and evidence.
Explanation:
In phylogenetic trees, two species are more related if they have a recent common ancestor. On the other hand, two species will be less related if their common ancestor is not a recent one and is located far away in the tree.
The phylogenetic tree is composed of,
• Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches.
• Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor.
• Root → This is the older common ancestor that all lineages share. The first one in the tree.
Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
• Apomorphies
• Plesiomorphies
• Homoplasy
In the exposed example, we have two trees.
Tree 1 ⇒ based on physical characteristicsTree 2 ⇒ based on structure, genetics, and evolutionary historyTree 1 reflects that the three species share a common ancestor that is far away in history. From this common ancestor (the blue point in the image), the duck first diverged. Later in evolution, Platypus diverged, and finally, Opossum diverged. The three species are morphologically well-differentiated from each other.
Tree 2 suggests a common ancestor of the three species (the blue point in the image), placed far away in history. From this common ancestor, the duck first diverged. But later in evolution, there was a second branch that diverged, and later originated Platypus and Opossum. According to the information provided by structure, genetics, and evolutionary history, Platypus and Opossum share a most recent common ancestor (the red point in the image).
Both trees provide equally important information. However, tree 2 is more detailed about evolutionary events because it involves many aspects of the animals´ history. Using one of the trees or the other, or both, will depend on the goals of the experiment.
The conclusion we can get from this comparison is that as long as there are discoveries and scientific advances, there will be a constant influx of information useful to recreate or explain evolution. Classification will keep changing with discoveries and evidence.

Classification can change with new discoveries and evidence.

El efisema pulmonar,provocado princioalmente por el consumo de cigarro, es una lesion que genera destruccion de los alveolos y, por lo tanto, zonas en las que no se produce el intercambio de gases ¿que consecuencias puede tener esta lesion en el organismo?
Answer:
El enfisema pulmonar disminuye la cantidad de tejido pulmonar, disminuyendo de este modo la cantidad de oxígeno que llega a la sangre (hipoxemia). El enfisema está asociado a diferentes trastornos incluyendo infecciones respiratorias recurrentes, pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores.
Explanation:
El enfisema pulmonar es una enfermedad causada por la destrucción de los alvéolos pulmonares la cual está asociada a un aumento en la dificultad para respirar. Las principales causas de esta enfermedad son la exposición continua al humo del cigarrillo y otras sustancias nocivas para la salud, como así también a contaminantes presentes en la atmósfera. El enfisema pulmonar va progresivamente destruyendo las paredes alveolares pulmonares y los vasos sanguíneos que las recorren, disminuyendo así la elasticidad pulmonar, aumentando la proporción de aire que recorre los pulmones y de este modo también aumentando la distensibilidad pulmonar. Esta enfermedad disminuye la capacidad de oxigenar la sangre, generando una sensación constante de falta de aire (disnea) y cuadros progresivamente más severos de hipoxemia. Cuando el enfisema pulmonar se encuentra en grado avanzado, la única opción viable es el reemplazo del órgano dañado mediante un trasplante pulmonar. El enfisema puede estar asociado a infecciones respiratorias recurrentes (resfriados, gripe), pérdida de peso, debilidad muscular e hinchazón de los miembros inferiores (tobillos, pies y piernas).

Answer:
> The answer to your query is the Second Answer Choice, or “The Lacey Act”
Explanation:
> The National Park System Act installed the National Park System agency, and ensures that they keep the National Parks safe and as they are intended.
> The Lacey Act prohibits the transportation, trade, selling, or simply possessing, any illegally caught or killed wildlife.
> The EPA (Environmental Protection Agency) makes sure that people and the environment are kept safe from health risks (Pollution, etc). They also enforce regulations on things that may cause harm to people and the environment.
> CITES (Convention on International Trade in Endangered Species) makes sure that there is no INTERNATIONAL trade on endangered species. This is between other countries, and with species that are becoming (or at risk of becoming) exctinct.
> We can match our story to the descriptions and find that it matches up with the second one, or the Lacey Act. Since he had killed a wolf on National Park Territory, and transported and possessed it, he is responsible for breaking the law prohibiting just that.
> Once again, the correct answer is the Second Answer Choice (The Lacey Act).
