If you observed pathological lung sections, record your observations. also record how the tissue differed from normal lung tissue. complete the table below using your answers.
Comparing pathological lung sections with normal lung tissue involves identifying unique abnormalities and signs of illnesses such as asthma and pneumonia, which alter the normal structure and function of lungs.
Explanation:Observing pathological lung sections involves identifying abnormalities in the lung tissue that differ from the normal lung tissue. Normal lung tissue does not have the characteristics of lung tissue during an asthma attack, typified by thickened mucosa, increase in mucus-producing goblet cells, and eosinophil infiltrates. A comparison to normal lung tissue allows for identification of pathological states, such as in asthma or pneumonia.
In the case of pneumonia, lungs may fill with mucus, show shadows in radiographic images, and produce a crackling sound during breathing. Furthermore, hypoxemia, a lower-than-normal level of oxygen in the blood, can be detected which is indicative of lung pathologies.

Widespread hunting of predators may result in _____.
a safer environment
overpopulation of prey
the arrival of new predators
an abundance of vegetation
Answer: Option B
Explanation: The population of prey inversely depends on the population of predators.
Predators are the organism that prey on other organism for their survival.
As they are inversely proportion to each other, more is the number of predators less is the number of prey and less is the number of predators more is the number of prey.
for example snake eat mouse, as here mouse is the prey and snake act as predator, if the population of snake decreases then the population of mouse will increase.
Thus, the correct answer is option B.
Teddy is afraid of needles and injections. whenever the nurse attempts to give him an injection, he screams and flails his arms and legs wildly. his heart rate increases, and he begins to sweat profusely, which indicates activation of the
Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system is responsible for changes in the body in stress or emergency situations. This leaves the individual on alert, ready for fight and flight reactions.
Since Teddy is terrified of needles, taking a shot is a very stressful time for him, so when he finds himself facing a needle in the syringe, his sympathetic nervous system is activated and his body goes into a fight and flight state, so , he begins to have reactions such as shouting and shaking his arms and legs wildly. In addition his heart rate increases and he begins to sweat profusely.

What observations and evidence have jonathan losos and his colleagues gathered to support the theory of natural selection?
A phenotypically normal woman with an abnormally long chromosome 13 (and a normal homolog of chromosome 13) marries a phenotypically normal man with an abnormally short chromosome 11 (and a normal homolog of chromosome 11). what is the probability of producing an offspring that will have both a long chromosome 13 and a short chromosome 11? if such a child is produced, what is the probability that this child would eventually pass both abnormal chromosomes to one of his or her offspring?
Final answer:
A child has a 25% chance of inheriting both an abnormally long chromosome 13 and abnormally short chromosome 11. If such a child is born, there is again a 25% chance that they would pass both abnormal chromosomes to their offspring.
Explanation:
The probability of producing an offspring with both an abnormally long chromosome 13 and abnormally short chromosome 11 depends on the inheritance patterns of these chromosomal abnormalities. Assuming each parent has one normal and one abnormal chromosome (long chromosome 13 in the mother, short chromosome 11 in the father), and that these abnormalities do not affect the gametes' viability, each child has a 50% chance of inheriting the abnormal chromosome from each parent. Therefore, the probability of a child inheriting both the long chromosome 13 and the short chromosome 11 is 25% (0.5 x 0.5 = 0.25).
If such a child is produced, the probability of this child eventually passing both abnormal chromosomes to one of his or her offspring follows the same logic. Each abnormal chromosome has a 50% chance of being passed on, so the probability of a child inheriting both abnormal chromosomes is also 25%.

What is the importance of the stop codon uag?
The importance of the stop codon UAG lies in its role in protein synthesis within cells. During translation, the process by which messenger RNA (mRNA) is decoded to produce a specific protein, the UAG stop codon serves as a signal to terminate the elongation of the polypeptide chain.
In the genetic code, each set of three nucleotides, called a codon, corresponds to either an amino acid or a stop signal. The UAG codon is one of the three stop codons (the others being UAA and UGA). When the ribosome, which is the machinery that reads the mRNA, encounters the UAG codon, it recognizes this as a termination signal. This triggers the release of the newly synthesized polypeptide chain from the ribosome, effectively ending the translation process for that particular mRNA molecule.
The accurate recognition of stop codons is crucial for the proper functioning of cells. If a stop codon is not recognized, or if it is mutated to encode an amino acid instead, the result can be an abnormally long protein or a nonfunctional one, which can lead to cellular dysfunction and disease.
Moreover, the UAG stop codon has gained attention in the field of synthetic biology. Researchers are exploring ways to repurpose UAG and other stop codons to incorporate non-standard amino acids into proteins, expanding the diversity of protein structures and functions that can be engineered.
In summary, the UAG stop codon plays a critical role in protein synthesis by signaling the end of translation, ensuring that proteins are made with the correct sequence and length, and it holds potential for future applications in the field of genetic engineering.

A solid keeps its shape due to which of the following factors?
A. Space between particles
B. Attractive forces between particles
C. The type of element in the solid
D. The container it is placed in
Answer:
Attractive forces between particles
Explanation:
There are three states of matter i.e solids, liquids and gases. All three states have different properties. A solid keeps its shape due to attractive forces between particles. These forces are called inter molecular forces. The particles of solid keeps with this force. There are few types of inter molecular forces
Ionic bondsVan-der-Waals dipole-dipole interactionsHydrogen bondingVan-der-Waals dispersion forces.Hence, the correct option is (b) "Attractive forces between particles".
A solid keeps its shape due to the attractive forces between particles.
Solids have their own shape and volume.
The particles that compose them are very ordered and the attractive forces between them are very large, so they do not flow and are very rigid.
About solids:
Its particles are oscillating around "fixed" positions of maximum stability.These positions or distances between atoms, of maximum stability are those that present the maximum attractive forces and the minimum repulsive forces.
The forces between the particles of a solid are high enough so that the cohesion of the crystal is maintained.This is due to the fact that the attractive forces are very intense and the particles are only free to carry out small vibrations and that is why solids have constant shape and volume.
Therefore, we can conclude that a solid keeps its shape due to the very intense attractive forces between particles.

How do the roots of most plants obtain food for survival?
A)They store food within them.
B)The phloem tissue carries food to the roots.
C)They survive by absorbing water from the soil.
D)They make their own food, like the rest of the plant.
ITS B The phloem tissue carries food to the roots.
Answer:
B)The phloem tissue carries food to the roots.
Explanation:
As you may already know, plants produce their own food through photosynthesis. However, these foods are produced in the leaves, but need to be distributed throughout the plants, including must reach the roots. Who distributes the products produced during the photosynthesis is Floema.
Phloem is an important tissue related to the conduction of elaborate sap (produced in photosynthesis) in the body of the plant. This means that it is through this tissue that substances such as water, sucrose, amino acids, nucleic acids, vitamins and inorganic ions are transported to all parts of the plant, including the roots.
is the number of deer on the island a density-dependent or density-independent limiting factor for the wolf ?
Answer:
It is density dependent.
Explanation:
Limiting factors, according to ecologists, are those that influence the size of a population. These factors are divided into dependent and independent. Dependent factors are those that influence mortality and birth rates in a population, in which case we can state that the number of moose on an island is a dependent limiting factor for the density of a wolf population.
This is because, wolves feed on moose, if the number of moose is small, the density of the wolf population will decrease because they will have difficulty feeding and consequently die. On the other hand, if the moose population is large, wolves will have abundant food and this will increase the density of the wolf population.

what type of bond keeps each individual DNA strand together?
Each DNA strand is held together internally by covalent bonds, while hydrogen bonds keep the two strands of the double helix joined, enabling them to unzip easily during DNA replication and repair.
The type of bond that keeps each individual DNA strand together is the covalent bond, which connects the sugar-phosphate backbone within each strand. Meanwhile, the two strands of the double helix of DNA are held together by hydrogen bonds. These hydrogen bonds are relatively weak, allowing the two strands to unzip during DNA replication, where each strand serves as a template for creating a new complementary strand.
The base pairing rules, Adenine (A) to Thymine (T) and Guanine (G) to Cytosine (C), are facilitated by these hydrogen bonds. Each base pair is connected by multiple hydrogen bonds - A and T by two hydrogen bonds, and G and C by three - to maintain the double helix structure of DNA.
In summary, the double-stranded structure of DNA is an artistic yet accurate portrayal of the hydrogen bonding holding the two strands together. This bond provides great strength when all are connected and allows for the necessary unzipping that occurs during DNA replication and repair processes.
Both external and organization factors shape internal pay structures.
