Answer:
Amoeba are unicellular eukaryotes found in aquatic environments. The organelle that is found in amoeba are nucleus, contractile vacuole and food vacuole and organelle found in plant cells are nucleus, endoplasmic reticulum, Golgi apparatus, vacuole, chloroplast, mitochondria, peroxisomes.
The organelles that are common in amoeba and plant cells are nucleus and vacuole. Both plant and amoeba have a membrane-bound nucleus in which their genetic material is packed.
The role of the vacuole in plant cell and amoeba is that it maintains the proper osmotic pressure in the cell and prevent cell from bursting. It also helps in the collection of waste material and its disposal.

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.

As discussed in the introductory passage, the normal human microbiota has coevolved with humans. this microbiota consists of a wide variety of organisms interacting with each other and with their human host. for a normal, healthy human host, how is/are the majority of these relationships described?
The vast majority of the relationships that can be observed between humans and microbiota are commensalism and mutualism. These relationships are the reasons to why these organisms thrive in their environment because the microbiota living inside humans are able to obtain food and energy immediate to their cellular process. Consecutively, humans are able to metabolize some food consumed through these organisms as long as they are regulated and monitored.
Describe how the articulating bones of the elbow prevent hyperextension
The articulating bones of the elbow prevent hyperextension through the support of ligaments and the articular capsule. The ulnar collateral ligament and the radial collateral ligament resist hyperextension, while the articular capsule prevents side-to-side movements.
Explanation:The articulating bones of the elbow prevent hyperextension through the support of several ligaments. The ulnar collateral ligament, located on the medial side of the elbow, is the strongest and resists hyperextension. The radial collateral ligament on the lateral side of the elbow also helps prevent hyperextension. Finally, the articular capsule of the elbow, which is thickened with intrinsic ligaments, prevents side-to-side movements, including hyperextension.

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.

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.
How does the use of assistive biomedical technology in children differ from the use of assistive biomedical technology in adults?
The use of assistive biomedical technology differs in children than in adults due to the following reason:
Children suffering from disorder like Down syndrome needs help to cope with that is learning how to adjust to the disorder. Adults suffering from this disorder need support to cope up with it, there is very less scope of learning.
Further Explanation:
The main term referred as biomedical technology is a combination of technology and engineering to solve the medical or biological issue in humans. The major difference between the use of the assistive biomedical technology in adults and children is mainly depending upon how the technology is modifying for the use of the particular age group. There are many different types of assessment devices for biomedical technology:
Cosmo-Bot Cosmo’s learning system Stroke rehab glove Tap-tap rehabilitation Learning for children
For example, in children, cognitive devices may assist in classroom learning, on the other hand, for an adult, a cognitive device may focus on the rehabilitation therapy post-stroke. Thus, mainly children require coping up from the disease and adults just require support.

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.
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.
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.
