Answer:
The stage of mitosis in which the cell divides in two is at the end of the telophase, through a process called cytokinesis.
Explanation:
Telophase is the final stage of mitosis and implies completion of cell division, in which the cellular structures are distributed and take their rightful place in each daughter cell.
In the telophase stage, the mitotic spindle also disappears, the cell nucleus has divided and distributed for each cell and the process of restructuration of cell membranes and endomembrane systems begins.
When the daughter cells are ready, cytokinesis occurs, with the distribution of the cytoplasm and each daughter cell is independent, surrounded by its respective cell membrane.

How are amphibians different from reptiles?
a) They do not breathe using lungs.
b) They cannot be fully terrestrial.
c) They do not have a backbone.
d) They are not ectothermie.
Answer: b) They cannot be fully terrestrial
Explanation:
I took the test
Amphibians are different from reptiles because the amphibians do not breathe using lungs however reptiles have lungs which help them breathe on land. Thus, the correct option is A.
What are the characteristics of Amphibians?
Amphibians are the four-limbed, ectothermic vertebrates who belongs to the Amphibia class of Phylum Vertebrata. All the living amphibians belong to the group Lissamphibia. They inhabit a wide range of habitats, with most of the species living within terrestrial, fossorial, or freshwater aquatic ecosystems.
Amphibians are different from reptiles in characteristics such as amphibians lay eggs in the water, and their young ones have gills which help them to survive in the water. They venture onto land only when fully mature. Reptiles, on the other hand, have adapted to live completely on the dry land. They are viviparous and breathe through lungs and not gills.
Therefore, the correct option is A.

How does increasing thermal energy affect kinetic energy AND the rate of particle movement?
I'm in first grade so please answer this question as a 7-year-old would. thanks
The particles gather kinetic energy and accelerate as the temperature rises. The actual average speed of the particles is influenced by both their mass and temperature; at a given temperature, larger particles travel more slowly than lighter ones.
What is the kinetic energy?A particle or an item that is in motion has a sort of energy called kinetic energy. When work, which entails the transfer of energy, is done on an object by applying a net force, that object acquires kinetic energy.
The relationship between a substance's temperature and its average particle kinetic energy is direct. These particles must move more quickly as the temperature rises because their mass is constant.
Therefore, increasing thermal energy affect kinetic energy AND the rate of particle movement.

in the phase of wound healing, collagen closes the gap between tissues and scar tissue forms
In the phase of wound healing, collagen closes the gap between tissues, and scar tissue forms. This phase is called the Remodelling phase because collagen continues to increase, and the tissue begins to contract with the help of fibroblasts, which adds strength to the new tissue.
However, gradually excessive collagen in the fibrin framework can cause scar tissue formation.
Therefore, at the injury site, the fibrin in blood stops the blood flow and provides mechanical support to the collagens, a protein that helps close the gap between injured tissues and gives strength to the newly formed tissue. This phase continues for six or more months. Thus, it is called as remodel or remodelling phase.

Explain over production and reproduction
Explanation:
Overproduction in Natural SelectionNatural selection occurs in specific populations of organisms because of several factors. It begins with overproduction. Overproduction by definition, in biology, means that each generation has more offspring than can be supported by the environment. Because of this, competition takes place for limited resources. Individuals have traits that are passed down to offspring. Some of these traits give individuals an advantage when it comes to surviving to reproduce. The organisms with these traits are more likely to live and have offspring who will inherit the helpful traits.

patterns and location of velopharyngeal valving problems: atypical findings on video nasopharyngoscopy
In 246 consecutive nasopharyngoscopy examinations, patterns of velopharyngeal (VP) valving and the location of velopharyngeal gaps were examined.
Velopharyngeal: What is it?Normal speech production depends heavily on the velopharyngeal valve. The structures that make up this valve are as follows:
Velum (also called soft palate) The side walls of the throat are called lateral pharyngeal walls. The back wall of the throat is known as the posterior pharyngeal wall.The coronal pattern of closure predominated (68%) and was followed by circular (23%), circular with a Passavant's ridge (5%) patterns, as well as sagittal (4%) patterns. In 181 patients, gaps were discovered, in 121, they were deemed typical (centrally located), in 28, they were in one of the lateral aspects of the valve, and in 32, they were attributed to abnormalities in the anatomy or function of the posterior border of the soft palate or to the shape of the adenoid tissue. Patients with a coronal valving pattern tended to have abnormal results. These findings highlight additional concerns regarding the care of patients with unusual valving issues.

The increased heart failure risk and sudden cardiac death are associated with Pathological cardiac hypertrophy.
Many transcription factors and miRNAs were implicated in cardiac hypertrophy, and In gene expression regulation their high combinatorial action is becoming more clear. Parallel expression profiles for messenger RNA (mRNA) and miRNAs were integrated from an in vitro model of cardiac hypertrophy with experimentally validated interactions from seven curated databases in order to build the cardiac hypertrophy-related transcription factors -miRNA regulatory network. Based on Borda count aggregation of distinct network-based properties they suggested a completely unsupervised technique to identify core regulatory elements.
By combining node scores derived from active pathways, motif-based centrality, and k-shell index which was able to prioritize biologically meaningful transcription factors and miRNAs as central nodes in the point potential active and network regulatory pathways in cardiac hypertrophy. Moreover, we identified recurrent associations in the crosstalk feed-forward loop motifs between transcription factors and miRNAs.Most transcription factors and miRNAs were immersed in specific interconnection patterns.

A scientist has been tracking and studying a population of deer in Yellowstone National Park. He surveys the population every six months. Usually, the population is thriving and has a gene pool with a wide variety of traits. But during one six-month period, an event occurred that affected the population, and when the scientist returned, the amount of genetic variation had decreased significantly. Which of the following is most likely the event that occurred to change the population? Yellowstone National Park expanded its borders. A population of wolves was introduced into Yellowstone National Park. The amount of disease in the deer population decreased. More grass and shrubs were planted in Yellowstone National Park.
Answer:
[tex]\boxed {\boxed {\sf B. \ A \ population \ of \ wolves \ was \ introduced \ to \ Yellowstone \ National \ Park }}[/tex]
Explanation:
Let's evaluate each choice. Remember we are looking for an event to decrease the genetic variation and population.
A. Yellowstone expanded its borders
If the park expanded, it's likely the population would increase. There would be more space and resources for the deer.B. A population of wolves was introduced
A wolf is a predator that preys on deer. If they were introduced, they would use the deer as a food source and decrease the population.B seems like a good answer, but let's check the others.
C. The amount of disease in the deer population decreased.
This would help the deer population. Less disease means fewer deaths and a greater population.D. More grass and shrubs were planted in Yellowstone
Deer are herbivores, so grass and shrubs would provide more food. This would keep the deer nourished and healthy, meaning a greater population.The best answer choice is B: A population of wolves was introduced into Yellowstone National Park

inhibition of proteolysis enhances aluminum-induced perikaryal neurofilament accumulation but does not enhance tau accumulation
AlCl₃-induced aberrant phosphorylation of Tau is degraded by the ubiquitin-proteasome pathway (UPP), however this process is site-specific and varies in different types of cells.
Why does aluminum cause an increase in perikaryal neurofilaments but not tau accumulation?Phosphorylated neurofilament (NF) epitopes are typically clustered within the axonal cytoskeleton of NB₂a/d₁ cells, as has been seen for neurons in situ. However, following exposure to aluminum salts and proteolysis inhibition, accumulations of phosphorylated NFs form in NB₂a/d1 perikarya. In the current study, we found that perikarya of cells exposed to both aluminum and the protease inhibitor C₁ (also known as "AllNal") were more strongly labeled by monoclonal antibodies directed against both non-phosphorylated and phosphorylated epitopes than cells treated with either aluminum or the protease inhibitor alone.
We also immunostained cells treated under these conditions with monoclonal antibodies targeted against phosphate-insensitive (5E2) and phosphorylated (PHF-1) tau epitopes because these monoclonal antibodies cross-react with tau. A rise in 5E2 immunoreactivity indicated that aluminum therapy, but not C₁ treatment, caused an accumulation of total tau isoforms. PHF-1 immunoreactivity was not increased by either medication, whether used alone or in combination. According to these results, changes in immunoreactivity with SMI antibodies corresponded to a rise in NF epitopes. Analyses using an immunoblot confirmed this. These findings suggest that deficiencies in proteolytic mechanisms contribute to the development of neurofibrillary pathology and highlight the possibility of multiple etiologies for human neuropathological conditions because proteolysis is apparently essential for maintaining the normal distribution patterns of phosphorylated NF epitopes.
