The nurse is observing a set of new parents to ensure that they are bonding with their newborn. What displayed behavior would indicate that the parents bonding is maladaptive?
Answer:
Neglecting the child
Explanation:
Maldatives behaviors are the behaviors that do not facilitate the parent-infant bonding, meaning that they are those behaviors that are hindering the process. And the best way of removing that is to encourage the behaviors that counter them.
The process of pointing out the responsiveness of the infant is a positive strategy for facilitating parent-infant attachment. Telling the mother that she must pay attention to her infant may be perceived as derogatory and is not
appropriate. Educating the mother in infant care is important; however, pointing out the responsiveness
of her baby is a better tool for facilitating mother-infant attachment. .

Explanation:
A wolf kills a deer that is infected with ________ of Echinococcus granulosis in its liver and eats it. After consuming the deer, the wolf's intestine becomes filled with a number of ________ produced from scoleces. These eventually release eggs into the wolf's intestines, which are released in its feces.
Answer:
The deer is infected with the parasite taenia Echinococcus granulosis, which is in the development stage of the fertile hydatid cyst. The wolf's intestine becomes filled with adult parasites, that eventually release eggs from their proglottids.Explanation: Echinococcus granulosis biological cycle.
The adult form of the parasite Echinococcus granulosis inhabits the intestines of canids, such as the dog or in the wolves, as in the exposed example. They might be 2 to 7 millimeters long, and in their anterior extreme, there is a segment known as scolex or head. The invertebrate attaches to the intestine wall by using its scolex. In the posterior extreme, there are the fertile segments of the animal, formed by three or four proglottids. The proglottides, carry the eggs and release them in the canid´s intestine. These eggs can get out of the animal´s body when it defecates. The parasite´s eggs are now in the feces of the canid.
Once on the ground or in the water, these eggs might be ingested by an intermediate host. In general, these hosts are animals such as sheep, goats, horses, pigs, and even humans. In the exposed example, the intermediate host is the deer.
The eclosion of the parasite´s eggs occurs in the thin intestine of their host, during digestion. The invertebrate penetrates the intestinal wall, from where it migrates to other organs, especially the liver and the lungs. At this point, the organism known as the oncosphere, turn into hydatid cysts. In its interior, it starts the protoscolex formation, making the size of the cyst to get bigger. When the protoscolex is completely formed, the fertile cyst is now infectious to the final host.
The final host (wolves) becomes infected when it feeds on the intermediate host. After ingestion, protoscolex gets released in the interior of the duodene. Their free state is known as scolex. At a certain point, scolex gets attached to the intestine wall where they stay until they become adults. And the cycle starts again.

it transmits information between different parts of nervous system.
Answer:
C. It transmits information between different parts of the nervous system.
Explanation:
The nervous system has two parts, the central nervous system and the peripheral nervous system.
The central nervous system includes the brain, and the peripheral nervous system includes the spinal cord.
The spinal cord is a long, thin, tubular structure that consists of nervous tissue. The spinal cord extends between medulla oblongata in the brain to the lumbar region. It is protected by the spinal column made up of bones, called vertebrae.
One function of the spinal cord is to receive and transmit signals to the entire body and back to the brain.
The spinal cord recieves nerve impulses from the body and transmits it to the brain. It also receives orders in form of nerve impulses which are transported to receptors for response.

lant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life processes where does it occur?.
Answer:
Two processes were described in this question, hence, the location of the two processes are as follows:
synthesize energy-rich organic molecules- CHLOROPLAST
Break them down to extract energy- MITOCHONDRIA
Explanation:
Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.
However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.

How could a scientist use the scientific method to learn more about the Cretaceous era?
First, it is necessary that this scientist decide on what point of the Cretaceous period he wants to study. Among several points he may want to study the evolution of microorganisms of that time, the life of a dinosaur species, or the evolution of dinosaurs, the flora that was established during this period, among others. This is the phase of the scientific method called Observation.
After that, he must enter the phase called "Elaboration of hypotheses" where he will raise questions about the point he decided to study. "How many flower species existed in that period?", "How many of these flowers can we observe today?" among others.
After that, he will enter the phase called "Experimentation", where he will establish a type of experiment and all the experimental factors and variables that will allow the hypotheses to be answered.
After the experiment he will collect the data that will be analyzed and that will give results that will answer the hypotheses previously established. This is the phase called "Analysis of the results".
At that moment, he will be able to reach the last phase of the scientific method, the phase called "conclusion", where he will show the conclusions that the experiment allowed to be established.
The Cretaceous period was a prehistoric period that took place between about 140 and 60 million years ago. If a scientist wanted to use the scientific method to learn more about this time, he should implement the following steps:
Identify an unresolved issue or problem that you would like to address. Make a hypothesis that raises answers to these questions or problems. Carry out a series of investigations and experiments dedicated to verifying the hypotheses raised. Finally, having verified the hypotheses, propose a law or rule for the investigated questions.Learn more in https://brainly.com/question/19496416
Briefly describe two ways in which the Hardy-Weinberg equation can be used to get information about a population.
Answer:
The Hardy-Weinberg equation can be used to gather valuable information about a population in the following two ways:
1) Estimating allele frequencies: The Hardy-Weinberg equation allows scientists to estimate the frequency of specific alleles within a population. By comparing the observed frequencies with those predicted by the equation, researchers can determine if the population is in genetic equilibrium, meaning that the allele frequencies are stable and not evolving over time.
2) Identifying evolutionary forces: If a population deviates from the expected Hardy-Weinberg equilibrium, it suggests that one or more evolutionary forces, such as natural selection, genetic drift, gene flow, or mutation, are at play. By analyzing these deviations, scientists can gain insights into the factors influencing the genetic makeup of the population and better understand the evolutionary processes driving changes in the population's gene pool.

How is the growth of land plants proof that there is carbon in the atmosphere? How does carbon exist in the atmosphere, biosphere, and geosphere all at the same time? (Site 1 )
Plants take the CO2 from the atmosphere which is used in Calvin's cycle to synthesize organic compounds that end up building the plant. This fact can be proved by marking the atmospheric CO2 with radioactive isotopes of carbon, afterwards using a Geiger counter the plant will present radioactivity.
The carbon in the atmosphere is most commonly found in the form of CO2
it has a concentration of 0.04%.CO2 is a byproduct of aerobic respiration
or combustion, for example, C6H12O6+6O2-->6CO2+6H2O. The CO2 is then used by plants in photosynthesis as mentioned earlier.
Carbon is present in the biosphere because all life is made of carbon.
Carbon is present in the geosphere most commonly under the form of hydrocarbons like methane(CH4). The carbon present in geosphere is a result of organisms decay and metabolic byproducts. For example, methanogen bacteria synthesize methane in anaerobic conditions reducing hydrogen in the presence of CO2(CO2+4H2⇒CH4+2H2O). Carbon in the geosphere can also be found in coal that becomes diamond under extreme pressure and temperature.
Carbon element exists in various parts of the atmosphere in the form of gases such as carbon dioxide. The growth of land plants proof that there is carbon in the atmosphere as they perform photosynthesis.
What is Atmospheric carbon?The atmospheric carbon refers to the carbon dioxide which is present in the atmosphere. The main source of this carbon dioxide is respiration in animals.
There is an exchange of carbon from the atmosphere, vegetation, soils and the organic matter of the atmosphere, ocean and fossil fuels all of these are continually changing. The carbon cycle is the cycle through which carbon is exchanged among the various parts of the globe that is the biosphere, geosphere, and atmosphere of the Earth.
The growth of land plants is a proof that there is carbon present in the atmosphere because the land plants use carbon dioxide and water to grow. Carbon dioxide and water are both the gases and important part of the atmosphere, so when they are combined they usually form a liquid. This liquid is then absorbed by the plants and they use it to make their own food through photosynthesis.

If a plant has a high concentration of minerals inside its root cells, but does not have enough energy for active transport, what could happen to the minerals?
Answer:
The minerals will not be move or transported to other part of the plants because active transport require energy.
Explanation:
Active transport is a process where molecules and ions are move against a concentration gradient by using energy.
This process require energy, for ions or molecules of minerals to be taken up by plants, it is first moved to the root hairs where they are in high concentration against in dilute concentration on soil Active Transport then occur in the roots where it is taken up to the plants with the use of energy.
If there is not enough energy, active transport will not occur and the minerals will remain in the root hair and will not be move to other part of the plant.
