Answer:

Secondary structure proteins folding

Explanation:

Alpha helix and pleated sheets are basically two types if secondary structure of Proteins.

In 1964, Bell Labs scientists Arno Penzias and Robert A. Wilson were conducting experiments with the Holmdel Horn Antenna, an extremely sensitive device originally used to detect radio waves that were bounced off Echo balloon satellites, and later Telstar, the first active communications satellite. These radio waves were so weak, that it became critical to eliminate all possible interference in order to detect them.

Despite taking all conceivable steps to eliminate interference, they continually detected a strange, buzzing noise that was coming from all parts of the sky at all times of day and night. They did a range of additional testing on the equipment, and even removed some pigeons that were nesting in the antenna and their associate detritus. Still, the sound persisted. They ultimately determined that the noise was coming from outside of our galaxy

Almost by chance, they later learned that researchers and astrophysicists Robert H. Dicke, Jim Peebles and David Wilkinson at nearby Princeton University were looking for a way to detect residual radiation that they believed would have resulted from the Big Bang. As it turned out, the radiation detected by Penzias and Wilson was a perfect match for what the Princeton researchers had predicted, and hence made history.

Arno Penzias (left), Robert Wilson (center) and Keith Jefferts (right) look through a model of the universe to the constellation Orion where, for the first time, they discovered carbon monoxide in outer space.

From the archives

An audio recording of the CMBR noise was captured and narrated by Robert A. Wilson. This discovery in 1964 by Penzias and Wilson, announced in a Bell Labs press release, earned the researchers a Nobel Prize in Physics and provided the basis for future astronomical discoveries.

The correct answer to this open question is the following.

The assumptions that the author makes when presenting the information are that the author makes a comparison of what could have happened on Easter Island to other places in the world that suffered a similar fate.

There is practically no other historical data that should be considered before making such claims. Indeed, what happened on Eastern Island, also called RAPA NUI by the natives, is a mystery. Yes, there are legends and oral tradition stories that refer to what could have happened, but nothing based on scientific terms that could be demonstrated. Theories varied form the possible scenario of the sinking of the Lemurian continent. Due to that incident, many natives decided to leave and sail to other regions of the planet such as Hawaii, the Polynesian islands, and of course, Easter Island.

Answer: In contrast to a mitotic division, which yields two identical diploid daughter cells, the end result of meiosis is haploid daughter cells with chromosomal combinations different from those originally present in the parent. In sperm cells, four haploid gametes are produced.

The product of meiosis is four haploid daughter cells with genetically different as compared to their parents.

Meiosis may be defined as the type of cell division in which a parent cell is able to synthesize four daughter cells that are haploid in nature. These daughter cells are genetically dissimilar with respect to their parents. It is also known as reductional division.

The process of meiosis generally occurs in the germ cells (sex cells) of males and females. The division of cells occurs twice in meiosis. Meiosis is generally completed in two steps that are as follows:

These steps are further divided into Prophase, Metaphase, Anaphase, and Telophase. Overall, it significantly determines the nature as well as the characteristics of a cell

Therefore, the product of meiosis is four haploid daughter cells with genetically different as compared to their parents.

Explanation:

Answer:

D. Plants grow best in sunlight.

Explanation:

The other answers can't be scientifically proven, therefore they would not make a good hypothesis. A hypothesis is a statement that can be tested and verified.

Plant will grow best in sunlight. So, the correct option is (D).

According to the evolution-immunity hypothesis in ecology, fast-growing plant species should suffer more from herbivores and pathogens than slow-growing species. Tests of this hypothesis have focused on above ground plant tissues, herbivores and pathogens. This should also apply to route defense.

When the amount of fertilizer applied to the plants is increased, the growth which is the height of the plant increases. As the amount of fertilizer increases, plant growth increases.

Plant growth shall be considered as an increase in plant volume and/or mass with or without the formation of new structures such as organs, tissues, cells or cell organelles that grow in the presence of sunlight.

Thus, plant will grow best in sunlight. So, the correct option is (D).

As water moves from the roots up through the stem of a plant adhesion is a property of water that enables this to happens. The characteristic of water causes adhesion is hydrogen bond. Thus, option D is correct.

Water has been defined as the water present in the underground water below the soil as well as in the crack of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are known as hand-dug wells, springs, and drilled boreholes.

The water stored under the ground has been obtained from rain and stored in ground so that it can be used later. Ground water has observed very clean and fit for drinking and the reason has been the soil present on top and work as filter and the groundwater is free from all microorganisms.

The use of groundwater is just to wash dishes and cooking utensils in cold, soapy water,Use a disinfectant wash cloth to clean the refrigerator. Rinse and wash contaminated clothing separately.

Explanation:

I got this answer correct when I took it.

The disruption which is not a major cause of a high extinction rate is: C. The use of animals in scientific research and experiments.

Extinction can be defined as a process or situation in which a species, family, or other taxonomic group of living organisms such as animals or plants become extinguished, destroyed, exterminated or dead.

This ultimately implies that, extinction literally means the extermination or dying out of a species, family, or other taxonomic group of living organisms.

Basically, the extinction of living organisms is mainly caused due to the effect of environmental forces and evolutionary changes such as:

In conclusion, the disruption which isn't a major cause of a high extinction rate is the use of animals or plants in scientific research and experiments because often times they are not killed and only a sample of the population is used.

so cell is part of matter cause matter compose everything int the universe

cells are the basic small and structural units of living matter and composed of organelle mostly made up of biomolecules.

Cell is the basic structural unit of any living system, present in animal, plant, microbes etc where Bacteria are unicellular in nature as it is composed of single cell, higher eukaryotic organisms are multicellular like plants and animal cell as it is made up of multiple cells.

The prokaryotic cells are simplest cell which have a cell membrane, cytoplasm and other cell organelles where the metabolic processes occur, ribosome is the organelle where protein synthesis occur, and nucleoid carry genetic information, reproduce by binary fission.

The eukaryotic cells are more complex which have cell membranes, cytoplasm, ribosomes, and nucleus, rough endoplasmic reticulum, smooth endoplasmic reticulum for lipids, Golgi apparatus for protein sorting and exporting.

Explanation:

This can be clarified with the idea of induced resistance. it is the capacity of a plant to react to the specific compound delivered from the damaged body parts, The dispersion of the synthetic animates all different plants parts and different plants to be less delectable and thusly not wonderful to eat. In this manner the more the degree of harm to the plant, the higher the volume of synthetic compounds delivered, and consequently the less delicious the plants and lower the harms negative criticism instruments. Since this reestablished the plants to moderately consistent inner environments, this is homeostasis.

Hornworm caterpillar harms tomatoes plants leaves, leaving holes. When a tomato plant is eaten, it discharges a compound substance called methyl jasmonate. The last would be gotten by adjoining plant parts or other tomato plants. The open tomato plants hence turn out to be less scrumptious. Subsequently, the caterpillar in the wake of crushing the underlying aspect of the tomato plants would not have the option to proceed with the taking care of and in this manner feed on each other prompting their death, turning them to cannabis caterpillars.  

Since trying to keep up the generally consistent interior condition plant discharges methyl jasmonate to forestall further harm and in this manner guarantees the soundness of the plant.
