You now find new cells which contains 200 mM CaCl2 and 15 mM glucose. The cell membrane is permeable to Ca ions, impermeable to Cl- ions, impermeable to Na ions and impermeable to glucose. You transfer these cells into a solution which has 140 mM (NaCl) and 150 mM glucose. What happens to the cells after the solution and cell have come to equilibrium
Answer:
The correct answer would be - ions will move from solution 1 to solution 2 so the cell will shrink.
Explanation:
The concentration of CaCl2- = 200mM
CaCl2 dissociates in the three different ions in a solution and each has the same osmolarity
The concentration of glucose = 15 mM
So, the osmolarity of solution 1 would be:
3 × 200 + 15= 615 mM
Similarly, the osmolarity of the second solution would be
The concentration of NaCl = 140 mM
The concentration of glucose = 150 mM
NaCl dissociates in the two different ions in a solution and each has the same osmolarity
140×2+ 150= 430 mM
The solution has more concentration of ions than solution two so the movement of the calcium ion of the CaCl2- would be possible only and therefore, the cell in solution 1 will shrink.
Which tier do ecologist studying when looking at communities of different species
interacting with each other and the abiotic factors of their environment?
ecosystem
biome
O
biosphere
community
Answer:
ecosystem
Explanation:
An ecosystem refers to the interaction/relationship between the biotic parts of a habitat with one another and also the abiotic parts. The biotic parts refers to organisms that possess life in them e.g plants, animals, microbes etc while the abiotic parts refers to the inanimate things e.g rocks, sea, land, soil etc.
Therefore, according to this question, an ecologist looking at communities of different species interacting with each other and the abiotic factors of their environment is studying ECOSYSTEM.

What process is carried out by RNA to produce a protein?
Answer:
During transcription, DNA is used as a template to make a molecule of messenger RNA. The molecule of mRNA then leaves the nucleus and goes to a ribosome in the cytoplasm, where translation occurs. During translation, the genetic code in mRNA is read and used to make a protein

Choose THREE examples that correctly predict the effect of a change on the ecosystem.
А
A decrease in the kangaroo rat population will cause a decrease in the coyote
population
B
A decrease in the desert tortoise population will cause a decrease in the
rattlesnake population
Wc
A decrease in the rattlesnake population will cause an increase in the kangaroo
Answer:
The answer is option A "A decrease in the kangaroo rat population will cause a decrease in the coyote population"
Explanation:
Climate is a significant ecological impact on environments. Changing Climate influences biological systems in an variety of ways. For example, warming may constrain species to relocate to higher scopes or higher rises where temperatures are more helpful for their endurance.
Environmental change not just influences biological systems and species straightforwardly, it likewise communicates with other human stressors, for example, advancement. Although a few stressors cause just minor effects when acting alone, their combined effect may prompt emotional natural changes. For example, environmental change may worsen the pressure that land improvement puts on delicate water front zones. Also, as of late logged forested zones may get defenseless against disintegration if environmental change prompts increments in substantial down pour storms.
Satellite imaging allows scientists to observe _______.
a.
where deforestation has removed the trees
b.
where deforestation has occurred but is recovering
c.
where deforestation has not occurred
d.
all of the above
Answer:
the answer is D. all of the above
Explanation:
i got 100% on my quiz :)
Satellite imaging allows scientists to observe where deforestation has removed the trees, where deforestation has occurred but is recovering, and where deforestation has not occurred. Thus, the correct option for this question is D, i.e. all of the above.
What is Deforestation?Deforestation may be defined as the process of cutting down trees or the clearance of forests for the purpose of urbanization and industrialization. It can involve the conversion of forest land to farms, ranches, or urban use.
According to the context of this question, satellite imaging may be defined as a type of technology that gathers or collects information across the world with the help of satellites. The activity of deforestation is analyzed by this process along with recovering the surface.
Therefore, the correct option for this question is D, i.e. all of the above.

Diffusion in membrane cell
Answer:
when small molecules pass through the lipid bilayer of a cell membrane simple passive diffusion occurs
Explanation:
Diffusion is one form of passive transport that doesn't require the expenditure of cellular energy. A molecule can diffuse passively through the cell membrane if it's lipid-soluble, uncharged, and very small, or if a carrier molecule can assist it. ... The assisted process is known as facilitated diffusion.
5. On vacation at a lake, Saira's mom sees an interesting-looking rock formation. Saira just learned
about rocks in geology class and tells her mom that the formation is made of gneiss, a type of
metamorphic rock. How did this metamorphic rock form?
Answer:it was heated and under pressure
Explanation:
Metamorphic rocks are formed from existing rocks, under high temperature and high pressure. This process is called metamorphism.
What is a metamorphic rock?Metamorphic rocks are those rocks that are formed from different kinds of rock like igneous, sedimentary, or gneiss rock under high pressure and intense temperature. They are rigid in nature.
In the formation of metamorphic rocks, firstly existing rock is broken down into small particles by physical, chemical, or biological agents. The process of breaking down rock is called weathering. Then erosion and transportation of these particles take place by the wind, water, or any biological agent.
The next step involves compaction after sedimentation. Thus, metamorphic rocks are formed from existing rocks.

How was the rotation rate of Jupiter's core determined?
-by observing the Great Red Spot
-by watching lo move across the disk of Jupiter
-by radio observations of Jupiter's rapidly spinning magnetosphere
-by measuring the oblateness of Jupiter's disk
Answer:
C. by radio observations of Jupiter's rapidly spinning magnetosphere
Explanation:
Jupiter refers to one of the planetary bodies in the solar system. It is considered to be the largest (twice as large or big as every other combined) planetary body and the fifth (5th) from the Sun.
Jupiter is a planet that rotates rapidly and as a result it is referred to as being noticeably oblate. It has the fastest rotation rate among the planets of the solar system because it completes a rotation about an axis in 9.9 hours.
The rotation rate of Jupiter's core was determined by radio observations of Jupiter's rapidly spinning magnetosphere.

Why postharvest physiology is important to maintain sustainable food supply on this planet. Please give named examples and discuss various biological factors associated with produce deterioration after harvest
Answer:
Postharvest physiology plays a fundamental role in extending the shelf-life and quality of plant products. An example of postharvest physiology methodologies is by reducing the temperature to improve shelf-life before consumption
Explanation:
Postharvest physiology refers to the methodologies used for extending shelf-life and quality, thus being a critical issue in food systems. Postharvest approaches include chemical treatments, temperature reduction, cleaning and disinfection methods, etc. Crop varieties are genetically selected in order to maintain nutritional qualities of stored seeds for a long time after harvest. These seeds are also controlled during storage by using postharvest handling practices (e.g., chemical and enzyme inhibitors that extend shelf life).

What are 5 different types of heterotrophs, what do they eat, and give an example of an organism for each category.
Answer:
Five different types of heterotrophs are carnivores, herbivores, omnivores, scavengers, and detritivores.
Carnivores eat the meat of other animals. Example: Bear
Herbivores eat vegetation. Example: Deer
Omnivores eat a combination of both meat and vegetation. Example: Humans
Scavengers eat things left behind by carnivores and herbivores. Example: Raccoon
Detritivores eat small bits of organic matter, such as soil. Example: Worms
Edit: If you'd rather substitute one of those for a decomposer, Decomposers break down dead or decaying organisms. Example: Mushroom, or fungi.
