Explanation:
You have isolated and purified a new species of cells from the rain forest and you want to place this new species in the appropriate branch of the tree of life. You sequence the ribosomal RNA genes from these cells and discover that for one particular region of the ribosomal gene (the rRNA) the RNA sequence is AAUGAAGG. You have sequences from the same region of the ribosomal genes (the rRNA) from each of these species: bacteria, eukaryote and archaea, which are listed below.
bacteria AUAGAUGG
eukaryote AAAGAAGG
archaea AAUGGAGU
Based on these sequence results, to which branch of the tree of life should you assign this new species?
a. eukaryote
b. archaea
c. bacterial
d. bacteria and archaea
e. There is not enough information.
Answer:
The correct answer is: option A. eukaryote.
Explanation:
The sequence of the newly found rRNA is AAUGAAGG is similar to the sequence is given for the eukaryote which is AAAGAAGG, there is only one exception at 3thirs position of the sequence which is instead of uracil there is adenosine. However, this could be a result of the transversion mutation where A converted into U of the period of evolution.
On the other hand, the rRNA of bacteria and archaea have a very high difference in their sequence with a change in one than one base.
NaCl dissociates into 2 particles in water Na and Cl. If the solution in question 4 contained 0. IM NaCl instead of 0.IM sucrose, what is the of the solution, and in which direction would the net flow of water be?
Answer:
-4.87 (see image for further explanation)
Explanation:
Water potential of solution will be − 4.87 The direction of water potential will be out of root into salt solution.
What is water potential?ψ = iCRT
Where, i = −2,
T = 273+ 20
R= 0.831
ψ = ( −2 ) ( 1) (0.831) ( 273+ 20)
= − 4.87bars
Water potential of a substance is equal to pressure
Ψ = ΨS + ΨP
Ψ = 0 + ( 4.87)
= − 4.87bars
Therefore, Water potential of solution will be − 4.87 The direction of water potential will be out of root into salt solution.

The Earth remained a frozen snow ball until carbon dioxide levels in the atmosphere increased. Why did carbon dioxide from the volcanoes fill the atmosphere?
Answer:
Because the land surface was then largely covered in ice, continental weathering effectively ceased. This locked the planet into a 'Snowball Earth' state until carbon dioxide released from ongoing volcanic activity warmed the atmosphere sufficiently to rapidly melt the ice cover. This model does not, however, explain one of the most puzzling features of this rapid deglaciation; namely the global formation of hundreds of metres thick deposits known as 'cap carbonates', in warm waters after Snowball Earth events.
The Southampton-led research, published in Nature Geoscience, now offers an explanation for these major changes in ocean chemistry.
Lead author of the study Dr Tom Gernon, Lecturer in Earth Science at the University of Southampton, said: "When volcanic material is deposited in the oceans it undergoes very rapid and profound chemical alteration that impacts the biogeochemistry of the oceans. We find that many geological and geochemical phenomena associated with Snowball Earth are consistent with extensive submarine volcanism along shallo

There are two different types of cell transportation. Which of the following requires energy?
a. Facilitated Diffusion
b. Active Transport
c. Osmosis
d. Simple Diffusion
please help :))
Answer:
The type of cellular transport that requires energy is active transport (option b).
Explanation:
Active transport —unlike passive transport— involves the passage of molecules or substances through the membrane against a concentration gradient, a process that requires the use of energy.
In the case of active transport the energy for the process comes from the ATP molecule and the mechanism for this to be possible is by means of an ATPase incorporated into the transporter.
The transport of glucose and the sodium-potassium and calcium pumps are examples of this type of transport.
The other options are not correct because simple diffusion, facilitated diffusion and osmosis are passive transport mechanisms that do not require the use of energy.

what do you think causes different phenotypes in organisms how does the phenotype depend on its genes (genotype)
Answer:
They difference in phenotypes is dependent on the genes. The more dominant gene will overpower a recessive gene, or if there are two recessive genes together, that will be the phenotype. When things are cross breaded they introduce different genotypes that allow for different looking phenotypes.
Example: Dominant blue flower (Bb) mixed with recessive yellow flower (bb)
B b
b Bb bb
b Bb bb
There is a 50/50 chance the offspring will be either blue or yellow
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that. When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
What is phenotype?A "phenotype" is simply an observable trait. "Pheno" simply means "observe," and it derives from the same root as "phenomenon."
The differences in phenotypes are determined by genes. The more dominant gene will completely overwhelm a recessive gene, or if two recessive genes coexist, the phenotype will be that.
When things are crossbred, unique genotypes are introduced, allowing for different-looking phenotypes.
Thus, in this way, phenotype is dependent on genotype of the organism.

Describe the path that energy takes, from solar energy reaching earths surface to energy used to power cell processes in animals
The path that energy takes, from solar energy reaching the earth's surface to energy used to power cell processes in animals - Animals eat the grass that captures the energy from the sun which gives the animal nutrients
The Sun is the primary source of energy for organisms and the ecosystems of which they are part.
Producers, such as plants and algae, get their energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter.This process begins the flow of energy through almost all food webs.The energy present in these photosynthetic organisms store then transferred to various animals when they feed on these plants and algae and get their food and energy.Thus, the correct answer would be - Animals eat the grass that captures the energy from the sun which gives the animal nutrients
