Explanation:
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:
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.
What is the Hepatic Portal Vein?
Answer: The hepatic portal vein is one of the most important vein that receives blood from the body and transports it into the liver for filtration and processing. This vein is part of the hepatic portal system that receives all of the blood draining from the abdominal digestive tract, as well as from the pancreas, gallbladder, and spleen.
‘Hepatic’ means of or relating to the liver, therefore the hepatic portal vein is a blood vessel that sends nutrient-rich blood from the gastrointestinal tract and spleen to the liver, but also delivers toxins to the liver that will be chemically modified in the proces of detoxication
Answer:
Explanation:
hepatic portal vein is located in the upper right quadrant of the abdomen. It is typically 8 centimeters long in adults. The portal vein is responsible for carrying blood from the GI tract, gallbladder, pancreas, and spleen to the liver.The hepatic portal vein originates behind the neck of the pancreas and is usually formed by the convergence of the superior mesenteric vein and the splenic vein, referred to as the splenic-mesenteric confluence.

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.

Use this link to read about the tundra biome, then answer the question provided. Describe animal interactions that affect populations in the tundra ecosystem.
Answer:
Animals that are interact in tundra ecosystem are Owls, foxes, wolves, polar bears, caribou, lemmings, and hares.
Explanation:
Animals that are found in tundra ecosystem have some special adaptation to survive the extreme cool temperature. this ecosystem consist of producer, herbivores and carnivores. Owls, foxes, wolves, and polar bears are carnivores which are present in low population while caribou, lemmings, and hares are herbivores which present in large number. These herbivores are the food of carnivores. And these herbivores feed on grasses present in tundra ecosystem.
Answer:
Animals have adapted to the harsh weather conditions and long winters of the tundra.
Animals migrate to eat insects that live there year round.
Many animals in the tundra hibernate during the long, cold winter months.
Animals are most active in the short summer as the snow melts and shallow wetlands form.

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.

Which macromolecules provide instructions for growth? O A. Lipids O B. Nucleic acids O c. Carbohydrates O D. Proteins
Answer:
B
Explanation:
The macromolecule which provides instructions for growth is nucleic acids. The correct answer is option B.
Macromolecules are large molecules made up of smaller subunits called monomers. There are four main types of macromolecules found in living organisms:
carbohydrateslipidsnucleic acidsproteins.Nucleic acids are macromolecules that store and transmit genetic information. DNA (deoxyribonucleic acid) and RNA (ribonucleic acid) are the two main types of nucleic acids. DNA contains the genetic instructions for the development and function of all living organisms, while RNA plays a key role in the process of protein synthesis. When cells divide and grow, they must replicate their DNA so that each new cell receives a complete set of genetic instructions.

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

My mistress' eyes are nothing like the sun;
Coral is far more red, than her lips red:
If snow be white, why then her breasts are dun;
If hairs be wires, black wires grow on her head.
I have seen roses damask'd, red and white,
But no such roses seel in her cheeks;
And in some perfumes is there more delight
Than in the breath that from my mistress reeks.
I love to hear her speak, yet well I know

I grant I never saw a goddess go,
My mistress, when she walks, treads on the ground:
And yet by heaven, I think my love as rare,
As any she belied with false compare.

which words in the sonnet indicate that the tone is satirical ?
Answer:
"black wires"
"reeks".
Explanation:
William Shakespeare's "Sonnet 130" is a satire or mocking critique of the conventional sonnets that writers write. In this sonnet, he talks of a young lady who is short of conventional beauty ideals.
In the given lines from the sonnet, the poet/ speaker talks of his mistress whose "eyes are nothing like the sun" and he keeps on describing her features as opposed to one praising his lover. Rather, the speaker in this sonnet uses the negative descriptions in describing his mistress, like calling her hair "black wires" and her breath "reeks", far from the delightful perfumes that a lady is supposed to exude.
Thus, the two words that have a satirical tone in the sonnet are "black wires" and "reeks".
