Which of the following is MOST directly involved in the motility and intercellular signaling in T-cells: W) filamentous actin X) 200-nanometer myosin fibrils Y) cathepsin-myosin complexes Z) microvilli

Answers

Answer 1

Answer:

W) filamentous actin

Explanation:

T cells are a type of white blood cells (leukocytes) that play a fundamental role in the immune system by determining the specificity of the immune response to specific antigens. In T cells, the remodeling of the actin cytoskeleton is critical for the movement of these cells through different tissue environments and for adjusting their behavior during the scanning of antigen-presenting cells. The actin cytoskeleton acts as a physical platform for intracellular signaling events that occur at the immunological synapse formed between a T cell and an antigen-presenting cell, thereby contributing to T cell activation.

There is a claim that lycopene, the reddish substance in tomatoes and peppers, is of value in protecting people from Alzheimer Disease, a neurological condition. How would you, as a Biomedical Research Scientist, go about to refute or substantiate this suggestion?

Answers

Answer:

Conduct a study to determine if lycopene obtained from tomato and pepper consumption is significantly associated with a decreased level of abnormally folded proteins in neurons of the cerebral cortex

Explanation:

Alzheimer's disease is an irreversible, progressive, brain disorder characterized by the loss of neurons (the main brain cells) and synaptic connections in the cerebral cortex and specific subcortical regions. It has been shown that Alzheimer's disease is associated with an abnormal folding of proteins such as amyloid and tau proteins in neurons, thereby leading to the loss of communication between brain cells. In consequence, in this case, it should be interesting to design a study in order to observe if lycopene obtained from tomato and pepper consumption can decrease the levels of abnormally folded proteins in neurons of the cerebral cortex, which is a pathologic hallmark of Alzheimer's disease. For this purpose, it is expected to form two groups of study: 1-one group composed of individuals that regularly consume tomatoes and peppers and 2-one group composed of individuals that do not consume these fruits, as well as a third 'control' group composed of individuals that obtain lycopene by consuming other plants (e.g., watermelon, pink grapefruit and redd carrots which are also high in lycopene). Subsequently, it should be necessary to experimentally determine if lycopene is significatively associated with a decreased level of abnormal amyloid and tau proteins in neurons of the cerebral cortex. Finally, the comparison between individuals that regularly consume tomatoes and peppers with the control group may result useful to determine if different lycopene sources may affect protein folding.

Many scientists claim that the facts support the belief that climate change is really happening. By examining scientific research and evidence, you will better understand issues and cut through the myths. As you read in the unit, it is important to carefully consider evidence because there is a lot of information in the public sphere that looks like science but it is not based on the scientific method. For this activity, you are going to do your own research on global warming and sort out the facts for yourself. Do research online to find evidence about global warming. To find reliable information, be sure that you use reliable websites, such as those from government organizations (.gov) or universities (.edu). You can also look at publications that are reputable, such as Popular Science, Discover, or National Geographic. Find a minimum of three sources that provide evidence about global warming.

Answers

Climate change is strong evidence of global warming. The data maintained by the concerned departments shows that as the graph of global warming rose, adverse changes in the climate occurred.

Therefore, an increase in global warming and change in climate is directly related. The increase in the speed of the melting iceberg can be seen as the temperature or global warming has increased.

What are the effects of climate change?

Climate is a very important factor in the lives of all living organisms, because it is one of the major factors that determine if a living organism is going to survive or not.

Climate change is said to occur when there are changes in the earth's climate system, which result in the formation of new weather patterns that last for a long time.

Climate change affects living organisms in different ways; while climate change is beneficial to some organisms, it is detrimental to some. For instance, in Europe, climate change (increase in temperature) has been found to have positive effects on some bird populations.

Thus, this could be the answer.

Answers

to be more resistant to that antibiotic

if an antibiotic eliminates 99.9% of the germs. It makes sense to assume that the new strain of bacteria will be more resistant to that drug than the old strain. Here the correct option is A.

The majority of the susceptible bacteria in the population are killed by the addition of a bactericidal antibiotic, while the resistant bacteria continue to exist. Only the resistant bacteria will continue to grow and multiply while being exposed to the antibiotic.

Antibiotic misuse, overuse, and ineffective infection prevention and control all contribute to the acceleration of antibiotic resistance. At all societal levels, actions can be made to lessen the effects and contain the spread of resistance.

Thus the correct opion is A.

If a rat required a high rate of insulin infusion to maintain a specific blood glucose level, then you could conclude that it is:_______

Answers

Answer:

The correct answer is: diabetic.

Explanation:

There are several species where diabetes can manifest, like rats, dogs, and humans. Diabetes Mellitus is a condition characterized by hyperglycemia (high blood sugar levels) and can lead to many complications that are life-threatening to the patients. This hyperglycemia can be caused by a variety of reasons, but they all include an insufficient reach of insulin (the most important hormone in blood sugar regulation) to the target organs - sometimes this occurs because the pancreas can't produce insulin, other times it's because the organs cannot receive it.

In patients in which insulin is NOT produced by the body, the administration of exogenous insulin is required for their survival - this seems to be the case with the rat mentioned in the case. This rat is an insulin-dependent diabetic.

They compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to sugar molecules. create an additional energy transfer when they these sugars or eat each other. As in other ecosystems, organisms in hydrothermal vent communities also transform into other forms, such as (energy of motion).

Answers

Answer:

- Hydrothermal vent ecosystems do not have sunlight available and hence there are no photoautotrophs.

- Instead, chemoautotrophs play the role of producers on which other organisms rely for energy. They oxidize compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to synthesize sugar molecules.

- Consumers create an additional energy transfer when they utilize these sugars or eat each other.

- As in other ecosystem organisms in hydrothermal vent communities also transforms chemical energy into other forms such as kinetic energy (energy of motion).

Explanation:

A hydrothermal vent is a geyser on the seafloor that is generated by underwater volcanoes or tectonic activity through which geothermally heated water erupts. Hydrothermal vent ecosystems contain hydrothermal microorganisms which are able to survive just outside the hottest waters. For example, Methanopyrus kandleri are hyperthermophile prokaryotic microorganisms that live in these ecosystems where they produce methane from reducing CO2. Chemosynthesizers are able to convert carbon molecules (e.g., CO2) and nutrients into organic matter by the oxidation of inorganic compounds such as hydrogen sulfide and/or ferrous ions. Moreover, hydrothermal vent ecosystems have the potential to support high biomass and productivity levels due to the establishment of symbiotic relationships between chemosynthesizers with respiring heterotrophs, which obtain energy from other organisms. Chemosynthesizers are eaten by other organisms (e.g., amphipods and copepods), whereas larger organisms (e.g., snails and crabs) form predator and prey relationships above these primary consumers.

Hydrothermal vent ecosystems do not have sunlight available and hence there are no photoautotrophs.

Instead, chemoautotrophs play the role of producers on which other organisms rely for energy. They oxidize compounds such as hydrogen sulfide to obtain energy for themselves. This energy is used to synthesize sugar molecules.

Consumers create an additional energy transfer when they utilize these sugars or eat each other.

As in other ecosystem organisms in hydrothermal vent communities also transforms chemical energy into other forms such as kinetic energy (energy of motion).

What is Hydrothermal ecosystem?

What is transaction between school and post school destination​

Answers

Answer:

The transition between school to a post school is a difficult phase in one's life because it opens a lot of adjustments whether it is socially, mentally and/or psychologically. Most students find it difficult to transfer because of these following reasons visit these links and see the answers below: brainly.ph/question/2641856, brainly.ph/question/2635171, brainly.ph/question/2627976

There are a bunch of strangers. Not all students are gifted with an extropersonal skills that allows them to make friends easily. Transition makes it difficult for introvert pupils to accept.

The new school is bigger than their previous school. Though in others the size of a place is not bothering their performance, there are individuals who find it difficult to adjust when it comes to the size of their environment. For example a student who studied in a small private school with only one section will find it difficult to adjust moving around a larger environment.

There are different teaching styles coming from the school's faculty. Learning styles are somewhat define by the teacher's teaching styles and strategies. In their previous school, some of the seniors might have already leaked the strategies used by the teacher in their school. But in a post school, some students are 100% newbie wherein they have no idea what is going on inside a class of a single professor or instructor. This is difficult since they do have to observe every single day and learn a new way to follow the lesson's phase.

Friends are not with the same post school. It is said that you can go through anything with your friends but most of the time you will never be with them when you transfer to a post school but still you need to move forward and learn to mix with the public.

Lessons are difficult and new. Most learners are not accustomed in learning quick in a new environment especially when the lesson is more difficult and new.

New policies are too intimidating to break. Some students are struggling when it comes to adjusting to rules whether it is inside the classroom or just a simple campus rule so they feel intimidated and and fearful in breaking one. But it must be remembered that rules keep the society moving forward peacefully.

Explanation:

There are different reason for an individual to fear and feel difficulty adjusting to a post school. But one must remember that humans are created with an adaptability skill that allows us to mix well with a new habitat and environment. Social skills are just part of our adaptability. You can just follow the wind and let the flow take you. Life is a constant change and all you have to do is to embrace it to make yourself belong anywhere you go.

fungsionalisme adalah?​

Answers

Answer:

Teori adalah suatu pendapat bagaimana dan kenapa sebuah fakta terjadi. (Macionis, 1997:15). Sedangkan Scupin dan De Corse (1995)mendefinisikan teori adalah kumpulan hipotesis yang tidak berhubungan yang menawarkan penjelasan secara umum untuk fenomena natural atau sosial. Salah satu teori Antropologi adalah fungsionalisme.

Teori fungsionalisme adalah teori dominan dalam antropologi. Teori ini memandang budaya sebagai satu kesatuan, dan mencoba untuk menjelaskan bagaimana hubungan antara bagian-bagian masyarakat yang tercipta dan bagaimana bagian ini fungsional (bermakan memiliki konsekuensi yang menguntungkan pada individu dan masyarakat) dan disfungsional (bermakna memiliki konsekuensi negatif). Teori ini memandang masyarakat sebagai sistem yang kompleks yang mana bagian tersebut bekerja bersama untuk mempromosikan solidaritas dan stabilitas; ini menandakan bahwa kehidupan sosia kita dituntun berdasar pada struktur sosial, yang pola perilaku sosialnya secara relatif stabil (Macionis, 1997)

Seluruh struktur sosial berkntribusi pada operasi masyarakat. Dua antropolog inggris terkemuka Radcliff Brown dan Bronslaw Malinowski, menggambarkan dua standar teori: Struktural fungsionalisme, yang menekankan pada keunggulan dari masyarakat dan menyusun para individu, dan bagaimana berbagai macam elemenfungsi struktur sosial untuk memelihara permintaan sosial dan keseimbangan. Dan Psikologi strukturalisme, yang mana menekankan pada kbutuhan individual untuk bertemu dengan masyarakat.

Kelemahan teori fungsional adalah gagalnya menjelaskan kenapa masyarakat itu berbeda atau justru memiliki kesamaan. Ontropolog fungsionalisme menganggap dunia tertib, memberi sedikit perhatian atau bahkan tidak memberi perhatian pada kompetisi dan konflik (Howard dan Dunaif-Hattis, 1992). Teori ini tidak berhubungan dengan sejarah, mengabaikan proses sejarah. (Scupin dan De Corse, 1995) teori ini juga tidak dapat menjelaskan perubahan sosial dan budaya, sebagaimana ia dulu memandang masyarakat sebagai sesuatu yang stabil dan tetap. meskipun memiliki kelemahan, teori fungsionalisme mempengaruhi perjanjian besar penelitian empirik dalam antropologi.
