TLRs are Group of answer choices the coatings of pathogens by complement. present in intact skin, sebum, tears, etc. phagocyte receptors that detect PAMPs. nonspecific leukocytes that secrete toxins onto the surface of virally infected cells. molecules that damage cells, resulting in cell lysis.

Answers

Answer 1

Answer: Phagocyte receptors that detect PAMPs

Explanation:

TLRs or Toll-like receptors, are a family of proteins that are part of the innate immune system. TLRs are transmembranous and recognize pathogen-associated molecular patterns (PAMPs), which are groups of chemical characteristics common to certain types of pathogens. Patterns detected by TLRs include lipopolysaccharide, a compound found on the surfaces of Gram-negative bacteria, and double-stranded RNA, which is an integral part of the life cycles of many viruses. These PAMPs are generally important for the survival of the pathogen, so they are well preserved. Activation of these receptors induces inflammatory responses in leukocytes of myeloid lineage, signaling via NF-κB, which is a transcription factor that activates pro-inflammatory genes. Activated TLRs also increase the production of co-stimulatory molecules such as CD80, CD86 and CD40. These proteins, expressed on the surface of antigen-presenting cells, are necessary for the activation of T-lymphocytes by dentritic cells and macrophages already showing antigens in their MHC type II molecules (Major Histocompatibility Complex, they participate in the presentation of antigens to T lymphocytes)

In addition, TLR-mediated signaling on antigen-presenting cells (APCs) plays an important role in linking the innate and adaptive immune responses.

Suppose that you are in charge of designing a fracking job site. Which of these locations would be most ideal for the site?

Answers

Answer:

B. On a flat, vacant plot in the outskirts of the city

Explanation:

Fracking, also known as hydraulic fracturing is a drilling method used in the oil and gas industry of most countries. It is the process whereby natural gas and petroleum is extracted from deep down the Earth. A crack is made in the rock layers, followed by the injection of a liquid called fracking liquid, which is usually water, at a very high pressure.

The process of fracking has serious environmental side effects e.g. release of harmful gases, noise pollution, water contamination etc. and hence, when choosing a fracking site, environment's sustainability and safety of people should be taken into account. This is why a fracking site cannot be designed in a residential city or around a neighborhood. The site should rather be designed in a location where it would pose a minimal environmental threat to the people e.g flat, vacant plot in the outskirts of the city

What are intermediate species? in an easy way to understand. And some examples?

Answers

Answer:

An intermediate is a species which appears in the mechanism of a reaction, but not in the overall balanced equation. Examples: Amphibian/land vertebrate (Pederpes)- Intermediate form between primary aquatic Upper Devonian amphibians and early tetrapods. Lizard/snake (Pachyrhachis)—Intermediate form of snakes and an extinct lizard-like reptile. It was a primitive snake with limbs.

Explanation:

Answer: These are certain species that create “connecting links” or something like that, between the fossil record of life which help to show the slow process of speciatin.

[speciatin- the formation of new and distinct species in the course of evolution.]

The town in this image is near an inactive volcano. If the volcano were to violently erupt, which location would be least affected by volcanic ash and lava?

Answers

Answer:

i think it is the state park im not sure but lmk if im wrong or right

Explanation:

The correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc., and the plane is least about to be affected by the volcanic eruption.

What is a volcanic eruption?

A volcanic eruption is a natural phenomenon that occurs when magma, ash, and gases are expelled from a volcanic vent or fissure in the Earth's surface. Volcanic eruptions can range from relatively small and quiet to explosive and violent, and they can have significant impacts on the environment and on human populations. Volcanic ash and lava can be carried by the wind over large distances, so the direction of the wind and its strength are important factors in determining which areas will be most affected. Areas that are located upwind from the volcano are likely to be more affected by volcanic ash and lava than areas that are located downwind.

Hence, the correct answer is the plane, as it is flying in the sky, but the lava from the volcano after its eruption can easily flow down to the park, hospitals, etc.

Explanation:

When objects of two different temperature are in contact, what happens?

Answers

Answer:

The answer is C.

Explanation:

This is because the objects will exchange thermal energy, until thermal equilibrium is reached, i.e. until their temperatures are equal. We say that heat flows from the hotter to the cooler object.

Energy is transferred from a warmer to a cooler object through the phenomenon of heat. For instance, a large pan of lukewarm water will gain heat from a lit match (a higher temperature object) (lower temperature object). Thus, option C is correct.

What change in temperature when object are in contact?

It feels warmer in your hands to hold a hot cup. The heat is moving from one object to another, which is what you are feeling. Your hands receive the hot chocolate's thermal energy.

Heat is exchanged when two objects are at different temperatures. Up until the two items are at the same temperature, the cooler object warms up. Always, heat energy moves from a hot object to a cooler one.

The colder end will get energy from the hot end as it passes through the rod. The temperature will eventually equalize across the entire rod. Wearing gloves is crucial when working with hot metal, for this reason.

Therefore, The warmer object transfer heat energy to the cooler object.

In the labeled diagram the fossils comes from the oldest organism an index fossil from the Cambrian period is labeled at the point D. Thus, option D is correct.

What is the index fossil about?

Index fossils, which is also known as the key fossils or the guide fossils, are fossils of the organisms that are used to help determine the age of rock formations and sedimentary strata. Index fossils are typically chosen because they are easily recognizable, widespread, and existed for a relatively short period of time.

They are used as "markers" for specific time periods, and the presence or absence of certain index fossils can help scientists determine the relative age of rock formations.

In this scenario, the index fossil labeled A is from the Jurassic period, which lasted from about 201 to 145 million years ago. The index fossil labeled B is from the Permian period, which lasted from about 299 to 251 million years ago.

Therefore, In the labeled diagram the fossils comes from the oldest organism an index fossil from the Cambrian period is labeled at the point D. Thus, option D is correct.
