Explanation

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.

Lets do numbering of the labels to make labelling clear.

1. The Colorado River carves land in Arizona to form the Grand Canyon.

2. Cracks form in a sandstone wall surrounding a house.

3. A marble statue near the science museum is changing color due to rainfall.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Answer:

Weathering:

2. Cracks form in a sandstone wall surrounding a house.

3.A marble statue near the science museum is changing color due to rainfall.

Erosion:

1. The Colorado River carves land in Arizona to form the Grand Canyon.

4. After a rainstorm, soil and rock pieces litter the roadways.

5. The sand dunes in the Sahara Desert are changing shape.

Explanation:

Weathering and erosion, in both the processes rocks are broken down into particles but both the processes are different from each other. Weathering can be physical, chemical or biological process in which rock particles degrade without any movement while erosion is purely a movement of sediments in which particles move from one place to another under the influence of water and wind.

So, on the basis of this difference we can classify each label to the correct location:

Weathering (no movement of particles after degradation):

2. Cracks in a sandstone wall of a house.

3. Changing color of marble statue due to rainfall.

Erosion (Movement of particles from one place to another):

1. Formation of Grand Canyon, when the Colorado River carves land in Arizona.

4. Soil and rock pieces litter on roadways after rainstorms.

5. Changing shape of dunes in sahara desert.

Answer:

weathering - colorado river carves land in arizona to form the grand canyon. cracks form in a sandstone wall surrounding a house. a marble statue near the science museum is changing color due to rainfall

erosion - after a rainstorm, soil and rock piees litter the roadways. the sand dunes in the sahara desert are changing shape.

Answer:

Negative feedback

Explanation:

Negative feedback is produced when a mechanism is amplified through an inverse loop, which tends to reduce the fluctuations in the system. In this case, the negative feedback mechanism represents a homeostatic response of the body where the release of a target hormone (hormone C) decreases in response to the increase of a protein (protein Q) upstream in the signaling pathway. Therefore, in this scenario, it is expected that negative feedback causes a decrease in hormone function.

Answer:

Answer:

B

Explanation:

Answer:

The water striders are the species, which are about half an inch in length and exhibiting a thin body with three legs set. The legs of water striders exhibit small hairs, which helps in repelling water and holding air. The water striders by repelling water stand on the surface of the water and the captivated air permit them to float and move readily.  

The legs of water striders are coated with hydrophobic substances, which helps in repelling water and assists in keeping the terminals of the legs from getting coated with water. In case, if the legs of the species were coated with a hydrophilic substance, then water would be drawn up by the legs and would make the striders break through the surface and thus would have a tough time to walk on water.

Explanation:

The question is not clear, so the clear question is as follows:

A cell has a 5 percent salt concentration. It is placed into a solution with a 0.5 percent salt concentration. What will happen to the cell?

Answer:

Cell will get swelled and burst

Explanation:

When a cell is placed in a solution with less concentration, then the solvent particles move from lower concentration to higher concentration through a semipermeable membrane and the process s called osmosis.

In this case also, the cell has higher concentration and the solution has less, so water will move into the animal cell, causing it to swell and burst after some time.

Hence, the correct asnwer is "Cell will get swelled and burst".

Answer:

Water will move into the cell, causing it to swell.

Explanation:

The cell has higher concentration of solute and a lower concentration of water than the solution it is placed in. This means that water will move into the cell, causing it to swell and ultimately burst.

There are many ways by which humans can positively impact Earth's resources. These include reforestation, reducing pollution, protection of endangered species, and mindful use of water and attempts to replenish the water bodies, etc.

The resources present on earth which were not formed due to any kind of human intervention are called earth's resources or earth's natural resources. There are various natural resources found on earth.

Energy resources like petroleum and natural gas, metallic resources like iron, copper, and gold, and nonmetallic resources like granite, sandstone, etc are some of the examples of various resources found on earth.

However, due to the rise in consumerism, these resources are being overexploited by humans which have resulted in their depletion.

But, the awareness of this is spreading fast and humans have adopted various measures to prevent negative impacts and induce positive impacts on the resources of the earth.

Therefore, humans can have a positive impact on Earth's resources.

Answer:

Answer:

Emerging properties may arise by transient interactions such as individual organisms building a population. Human interaction in populations leads to the emergence of language, poetry, musical composition, and art. When populations of different species interact, communities form. Many emergent properties are the result of interactions between species in communities.

Emergent properties are characteristics of a system that do not exist in any of its constituent parts individually but originate as a result of interactions between those parts.

These characteristics are frequently intricate and challenging to forecast. Emergent characteristics are a crucial idea in several disciplines, including physics, chemistry, and biology.

Emergent qualities in biology can be observed in an organism's behaviour. For instance, a flock of birds' behaviour is an emergent characteristic of the individual birds that make up the flock.

The behaviour of the flock is a product of interactions among the individual birds and is not exhibited by any one individual bird. Similar to this, a school of fish's behaviour is an emergent characteristic of each fish.

Emergent features in chemistry can be observed in how molecules behave. An emergent attribute of a substance's individual molecules, for instance, is the substance's boiling point. The boiling point is not a property of any one molecule, but rather the outcome of interactions between the molecules.

Particle behaviour in physics exhibits emergent features. An emergent attribute of a material's individual particles, for instance, is the material's electrical conductivity.

The interactions between the individual particles produce the electrical conductivity, which is not a property of any one of the individual particles. As a result, emergent properties are characteristics of a system that develop.

Options

A. Mitosis

B. Meiosis

C. Apoptosis

D. Phagocytosis

Answer:

A

Explanation:

Mitosis is a type of cell division which takes place in living  organism during growth and development.Therefore it is ensures  the regenerations of cells and tissues during healing.

Therefore the restoration of new cells to the skin following injuries is due to mitosis.Since this is a multiplication division(2n) in which the daughter cells are exactly like the parents' cells the new tissues of the skin by mitosis, look exactly like the previous one that was injured.

In cases where the mitotic growth control is lost, the scare tissues of the injured part overgrows with granulation tissues and this leads to Kaloids.

      Its is a mass of Collagen Type 1.(Collagen is an  fibrous proteins  which has largest proportion in mammals).

Keloids  is characterized with pink or red coloration and elevation of the area,excessive growth of the area, with irritating  patch skin

Explanation:

Piaget proposed the theory of cognitive development, which talks about how human intelligence is developed. Piaget worked with Children because he believed they played a significant role in the development of cognitive intelligence. Based on his work, he proposed four stages of cognitive development viz: sensorimotor, preoperational, concrete operational and formal operational stages.

However, in the preoperational stage, Piaget described children between ages 2-7 as being in this stage of cognitive development where they are yet to comprehend mental logic. One characteristics of this stage is CONSERVATION, which is the ability to know that changing a substance's appearance doesn't change the properties of that substance. Piaget proposed that Children between the ages of 2-7 lacked this conservative characteristics.

He performed an experiment where he used two beakers with the same amount of liquid. He then emptied the contents of one of the previous beakers into a new beaker with different shape (longer). Piaget was able to notice that Children at the pre-operational stage were unable to understand that the contents of the two beakers (longer one and previous beaker) were still the same despite the beaker has been changed.

Hence, according to Piaget, a child has acquired the cognitive skill of conservation when he/she is able to understand that six ounces of liquid in a jar and six ounces in an elongated tube are equal.

Answer:

A. Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes

Explanation:

Endosymbiont theory deals with how eukaryotic organisms were formed from prokaryotic organisms. Prokaryotes such as Bacteria were documented as the first form of life on earth through fossil records before eukaryotes came into light.

Organelles such as Chloroplasts and mitochondria replicate in a similar manner as some prokaryotes. This supports the endosymbiont theory that present-day eukaryotic cells are descendants of a successful symbiotic relationship between a host cell and an engulfed prokaryote

Answer:

Cardiac arrest is the abrupt loss of heart function in a person who may or may not have been diagnosed with heart disease. It can come on suddenly, or in the wake of other symptoms. Cardiac arrest is often fatal, if appropriate steps aren’t taken immediately.

Each year in the United States, more than 350,000 cardiac arrests occur outside of a hospital setting.

These two distinct heart conditions are linked. Sudden cardiac arrest can occur after a heart attack, or during recovery.  Heart attacks increase the risk for sudden cardiac arrest. Most heart attacks do not lead to sudden cardiac arrest. But when sudden cardiac arrest occurs, heart attack is a common cause. Other heart conditions may also disrupt the heart’s rhythm and lead to sudden cardiac arrest. These include a thickened heart muscle (cardiomyopathy), heart failure, arrhythmias, particularly ventricular fibrillation, and long Q-T syndrome.

Cardiac arrest is reversible in most victims if it's treated within a few minutes. First, call 911 for emergency medical services. Then get an automated external defibrillator if one is available and use it as soon as it arrives. Begin CPR immediately and continue until professional emergency medical services arrive. If two people are available to help, one should begin CPR immediately while the other calls 911 and finds an AED.

Sudden cardiac arrest is a leading cause of death – over 320,000 out-of-hospital cardiac arrests occur annually in the United States. By performing Hands-Only CPR to the beat of the classic disco song “Stayin’ Alive,” you can double or even triple a victim’s chance of survival.

Explanation:

The question asks to pick the question that is least likely to lead to a scientific investigation based on these findings. The question states that the HGP identified sequences of base pairs in human DNA as well as many genes. The other questions were very likely to have arisen bases off of these findings. Criminal identification based on DNA is not the focus of the Human Genome Project.
