A new microorganism is isolated from a lake and is placed into a solution of KCl. The voltage difference across its membrane is measured at 120 mV. How much energy is required to move a proton from the negative side of the membrane to the positive side?
Answers
Answer: [tex]\Delta U=[/tex] 1.922x10⁻²⁰ Joules
Explanation: Electric Potential Energy (U) is the energy a charged object has due to its location in an electric field and it will only exist with the object is charged.
Voltage or Electric Potential Difference (V) is external work done to move a charge from one point to another in a electric field.
These terms have a relationship, which is given by:
[tex]\Delta U=q\Delta V[/tex]
where
q is the charge
Proton is positive and has a charge of 1.6x10⁻¹⁹C.
Unit for potential energy is Joule (J). The relation between mV and J is
1mV = 10⁻³J
Then:
V = 120x10⁻³
V = 0.12
So, for a proton to move from the negative side of a membrane to the positive:
[tex]\Delta U=q\Delta V[/tex]
[tex]\Delta U=1.6.10^{-19}.0.12[/tex]
[tex]\Delta U[/tex] = 1.922 x 10⁻²⁰
Energy necessary to transport a proton from negative side of the membrane to the positive is 1.922 x 10⁻²⁰J.

Vacunas
Explanation:
Las vacuna son preparaciones seguras obtenidas mediante numerosos ensayos clínicos, cuyo objetivo es generar inmunidad contra una enfermedad mediante la producción de anticuerpos. Basicamente, existen tres tipos de vacunas: vacunas atenuadas, vacunas de ARN mensajero y vacunas de terapia genética. En primer lugar, las vacunas atenuadas están desarrolladas usando fragmentos del virus que provoca la enfermedad, lo cual se conoce como vacunas atenuadas porque están fabricadas con virus atenuados/inactivados. Por otra parte, en los últimos años, han sido desarrolladas vacunas derivadas de ARN mensajeros (ARNm) las cuales permiten sintetizar una proteína específica del virus (antígeno) y de este modo generar una respuesta inmune que permanecerá ante una posible infección. Finalmente, las vacunas de terapia génica utilizan como vector un virus que no se integra al genoma pero que es altamente estable, como por ejemplo un adenovirus (un virus del resfriado común), el cual permite introducir en las células la información genética del patógeno a fin de generar proteínas virales específicas capaces de desencadenar una respuesta inmune, es decir, generar anticuerpos específicos, contra el virus.

Most species of deer are known to eat many different types of plants. Other than being herbivores, identify the category of species that explains how deer are very adaptable to new environments.
Answers
Answer:
they are invasive species
Explanation:
Invasive species can be defined as a category of non-indigenous species that may cause environmental harm. Invasive species have a high fecundity rate, an important dispersal capacity, highly plastic phenotypes, general habitat preferences, ability to circumvent biological controls (i.e., competitors, predators, diseases), etc. In consequence, these features become invasive species practically impossible to eliminate after introduction into a certain area and highly adaptable to new environmental conditions.
The category of species that describes how most species of deer can adapt to new environments is: invasive species.
Note the following about Invasive species:
Invasive species are usually non-native species in a new environment.They have high fecundity rate, meaning they reproduce faster.They have variety of food they can become adapted to feeding on.They have high survival rate.They can invade an habitat and disrupt the ecosystem.They are pretty difficult to control.Most species of deer is are typical examples of invasive species.
Therefore, the category of species that describes how most species of deer can adapt to new environments is: invasive species.

List and describe the different types of connective tissue. What similarities and differences did you observe?
Answers
Answer:
There are three types of connective tissues, loose connective tissues, dense, and hyaline.
Explanation:
The difference between them is the composition of the extracellular matrix that surrounds the fibroblast, that is to say that in loose connective tissue, the function will be of support or filling, and the fibroblast is immersed in an extracellular matrix with a high content of water and proteins. collagen.
On the other hand, in dense connective tissue, the amount of collagen fibers is greater, the protein structure as well, and the interlacing between proteins is more complex, and they may also have the ability to calcify as in the case of bone tissue or cartilage.
Finally, we have the hyaline connective tissue, which is very rich in hyaluronic acid and is found in the joints forming the discs, which are shock absorbers and protectors from bone wear due to friction between surfaces, hyaluronic acid, proteinglycans and glycoproteins are the main protagonists of all connective tissues together with the fibroblast, but even more so in the hyaline connective.

Question 6 options:
How they formed; intrusive rocks formed from lava and extrusive rocks are form from magma
How they formed; extrusive rocks formed from lava and intrusive rocks formed from magma
Where they are found; extrusive rocks are only found above ground
Where they are found; intrusive rocks are only found above ground
Answers
Answer:
The correct answer is - Where they are found; extrusive rocks are only found above ground
Explanation:
Intrusive and extrusive rocks are the two formed in Yellowstone natIonal park but there is how and where they formed that makes them different from one another. they both are igneous rocks.
The major difference between extrusive rocks and intrusive rocks is that extrusive rocks are formed on the surface or above the earth's surface from the lava that is magma thurst out from underground. Intrusive rocks are formed within the crust from the magma after cooling down and solidify.

Acceleration(a) :- 4m/s2
Time Taken(t) :- 50 Seconds
{ok a formula is there —->>> s = ut + 1/2 at2(it is ‘t’ square)….. now we will write like this and yeah don’t write this}
We Know,
s = ut + 1/2 at2
s = (15*50 + 1/2 *4*50*50)m
s= (750 + 5000)m
s = 5750 m
Therefore distance traveled is 5750 meters.

The axial skeleton includes the bones that form the skull, laryngeal skeleton, vertebral column, and thoracic cage. The bones of the appendicular skeleton (the limbs and girdles) “append” to the axial skeleton.
The appendicular skeleton is the portion of the skeleton of vertebrates consisting of the bones that support the appendages. There are 126 bones. The appendicular skeleton includes the skeletal elements within the limbs, as well as supporting shoulder girdle pectoral and pelvic girdle.

What was the result of using drainage blocks to keep water in the field level during the growing season?
Answers
Answer:
This question is incomplete
Explanation:
This question is incomplete. However, it should be noted that the idea of blocking the drainage, which could cause waterlogging (since the water will not be able to leave the field), is a type of irrigation that ensures there is sufficient amount of water for the plants to grow during a growing season. Although, some plants do not grow well in environments like this (in the case of waterlogging) because this environment lowers oxygen level in the root o the plant (caused by the water at the top of the soil).

Why were some of Schwann and Schleiden’s ideas about cells incorrect
Answers
Answer:
One of Schwann and Schleiden’s ideas was that cells were originated by spontaneous generation, which was later rejected by Virchow.
Explanation:
Schwann studied animal tissues, and by observing them, he concluded that tissues were made of cells.
Simultaneously, Schleiden arrives at the same conclusion when studying vegetable tissues.
Around 1830, they met and together proposed the first cell theory. The theory stated that:
Every living being is made of cells.Cell is the basic unit of life. Cells are originated by spontaneous generation.Virchow, who studied human tissues, during his observations sow the cell in its dividing process. He then proposed that cells were not originated from spontaneous generation, but they were the product of other pre-existing cells and were originated by cellular division. He rejected the third state of Schwann and Schleiden’s ideas.
