The hypothesis that is supported by these observations is that the dsRNA inhibited the translation of mRNA into protein (third option).

In this experiment, the C. elegans worms were transcribing eaf-1 into mRNA but not producing the eaf-1 protein. This phenomenon shows that dsRNA inhibited the translation of mRNA into protein related to the action of E. coli on the worms.

This also explains why the worms affected by this bacteria had fewer offspring and the offspring were smaller.

Answer:

It provides nutrients and gases to cell.

Explanation:

Osmosis is very important for the survival of a cell because due to osmosis, nutrients, water and gases enters in the cell. Osmosis is a type of diffusion in which solutes enters inside the cell through a semi-permeable membrane. This semi-permeable membrane only allows micromolecules such as glucose while does not allow to enter macromolecules such as carbohydrates and proteins due to small size of the holes of semi-permeable membrane.

Osmosis is important to the survival of a cell because it's the primary means through which water is transported in and out of cells.

Osmosis refers to the net movement of solvent molecules from a side of a semi-permeable membrane to another side.

Osmosis is important in living organisms as it helps in influencing the distribution of nutrients. Also, osmosis is vital for the release of metabolic waste products.

The plasma membrane defines the boundary of the cell and determines the nature of contact with the environment.

The plasma membrane is the outermost layer of an animal cell. It is composed of peptidoglycan and has a lipid bilayer with proteins embedded in it.

The plasma membrane is also known as cell membrane and is a selectively permeable membrane. It allows certain molecules and solutes to enter into the cell and go outside of the cell whenever necessary.

Plasma membrane plays a vital role in the communication between two consecutive cells as it is selectively permeable. The plasma membrane also maintains the concentration of the cell, by releasing or allowing certain solutes to enter and go out of the cell.

Motility characteristics of a free-living bacteria have mitochondria lost over time

A mitochondrion is a kind of organelle present in the cells of most eukaryotes, including mammals, plants, and fungi. Mitochondria have a double membrane structure and employ aerobic respiration to produce adenosine triphosphate (ATP), which is used as a source of chemical energy throughout the cell. Albert von Kölliker identified them in the voluntary muscles of insects in 1857 .

Carl Benda invented the name mitochondrion in 1898. The mitochondrion is commonly referred to as the "powerhouse of the cell," a term originated by Philip Siekevitz in a 1957 essay of the same title.

Answer:

\(pH=2.9\)

Explanation:

Hello,

In this case, the pH is computed by:

\(pH=-log([H^+])\)

Whereas the concentration of hydrogen ions equals the concentration of the acid for strong acids such as hydrochloric acid (HCl) due to its complete ionization in solution, which means that such concentration is 0.00125 M. Thus, the pH turns out:

\(pH=-log(0.00125)\\\\pH=2.9\)

Regards.

By definition, the pH of a 0.00125 M HCl solution is 2.90.  

You need to know that pH is the Hydrogen Potential. It is a measure of acidity or alkalinity that indicates the amount of hydrogen ions present in a solution or substance.

Mathematically, pH is calculated as the negative base 10 logarithm of the activity of hydrogen ions:

pH= - log [H⁺]

The numerical scale that measures the pH of substances includes the numbers from 0 to 14. The pH value 7 corresponds to neutral substances. Acidic substances are those with a pH lower than 7, while basic substances have a pH higher than 7.

On the other side, a strong acid is an acid that dissociates completely in solution at constant temperature and pressure. Under these conditions, the concentration of a strong acid is equal to the concentration of hydrogen ions (Hydronium or H₃O⁺).

In this case, HCl is a strong acid. Then: [HCl]= [H⁺]= 0.00125 M

Reeplacing in the definition of pH:

pH= - log 0.00125 M

Solving:

pH= 2.90

Finally, the pH of a 0.00125 M HCl solution is 2.90.

The two pieces of evidence that support the theory of the expanding universe are the red shift of light from distant stars and the existence of cosmic background radiation.

The correct answer is option B.

1. Red shift of light from distant stars: The observation of redshift in the light coming from distant galaxies provides evidence for the expansion of the universe. Redshift occurs when the light waves from an object moving away from an observer are stretched, causing a shift towards longer wavelengths. This phenomenon is consistent with the Doppler effect, where the wavelength of light appears to stretch as the source moves away. The redshift of light from distant stars indicates that galaxies are moving away from us and from each other, supporting the idea that the universe is expanding.

2. Existence of cosmic background radiation: The discovery of cosmic background radiation further supports the theory of the expanding universe. Cosmic background radiation is a faint, uniform microwave radiation that permeates the entire universe. It is believed to be residual radiation from the Big Bang, the initial event that is thought to have initiated the expansion of the universe. The presence of cosmic background radiation provides strong evidence for the hot, dense early stages of the universe and its subsequent expansion.

Here is an analysis of the changes in vegetation and species diversity based on the data:

In the first years after logging, the area was dominated by grasses, with 32 species present after 1 year. Shrubs and trees were initially absent. This indicates that grasses rapidly colonized the disturbed area after logging.

Over time, the number of grass species declined as shrubs and trees became established. Shrubs first appeared after 5 years and gradually increased, with 18 species present after 45 years. Trees were absent for the first 15 years but then increased to 24 species after 45 years.

The total number of species showed a steady increase over the 45 years, from 32 species initially to a maximum of 77 species after 45 years. This indicates that species diversity was low immediately following the disturbance but gradually recovered and surpassed the original diversity levels.

The pattern of changes suggests that after the initial disturbance of logging, grasses were the first vegetation to recover and colonize the open area. Then over time, shrubs and trees established and the plant community transitioned from grasses to shrubs to trees. This successional progression from early to later species resulted in an overall increase in species diversity as different types of plants colonized the area.

In summary, the key conclusions supported by the data are:

Answer:

Photosynthesis is a process whereby plants uses sunlight to prepare their own food using sunlight and without energy such as heat cannot perform its functions.

The contradiction arises from the fact that vitamin D and PTH both have different roles in calcium metabolism.

Vitamin D is necessary for calcium absorption from the intestines and for calcium transport from the kidneys to the blood. PTH, on the other hand, is responsible for mobilizing calcium from the bones. Therefore, when PTH is present, vitamin D helps to stimulate the mobilization of calcium from the bones, leading to bone loss. This is why a balanced intake of both vitamin D and PTH is important for maintaining healthy bones.

What is PTH?

Parathyroid hormone (PTH) is a hormone secreted by the parathyroid glands in the neck. It plays an important role in calcium metabolism by controlling the release of calcium from the bones into the bloodstream. It also helps to regulate the absorption of calcium from the intestines and its excretion in the kidneys. PTH also helps to stimulate the production of vitamin D, which is also necessary for calcium metabolism.

In conclusion, vitamin D and PTH are both important for maintaining healthy bones, but they have different roles in calcium metabolism. Vitamin D is necessary for calcium absorption from the intestines and for calcium transport from the kidneys to the blood, while PTH is responsible for mobilizing calcium from the bones. When PTH is present, vitamin D helps to stimulate the mobilization of calcium from the bones, leading to bone loss. Therefore, it is important to maintain a balanced intake of both vitamin D and PTH for healthy bones.
