Plants move water from the roots of the plant to the leaves through transpiration. As water evaporates from the leaf, cohesion pulls water up from the roots. Suggest a relationship between transpiration and stomata density.
Answer:
Stomata are the organs present on the stem and leaves of the plant and help in the gaseous exchange and evaporating water present in the aerial parts of the plant. Mainly leaves stomata plays role in gaseous exchange and transpiration which is the evaporation of the aerial water of plants by opening and closing the stomata. Stomata are small pores mostly and normally present under the leaves and regulated by the guard cells, dum bell shaped cells to close or close it.
Other than closing and opening the stomata, stomata density also can affect the rate of gas exchange as well as transpiration. Stomata density is the presence of the numbers of the stomata per unit area. In heat or sunny area the stomata density is higher than the shady or dark area to increase the transpiration in order to cool down the leaves of the plant which prevent the chloroplast proteins to denature.
The higher stomatal density should increase the total number of stomata per plant.
Consider our yeast CRISPR-Cas9 experiment: yeast are transformed with the PML 104-9RNA1 plasmid + HDR1 template to edit the ADE2 gene. Enter your answers below.
a. In yeast, what is the template from which the gRNA is transcribed?
b. The HDR fragment must enter the of the yeast cell to be used for homology directed repair.
c. The Cas9 gene is transcribed from the ____________as template, the transcript is transported from the _______to the ____________of the cell, and then the protein is translated.
d. After translation of Cas9, what happens? Explain in ONE sentence.
Answer:
a. The guide RNA (gRNA) is transcribed from the PML 104-9RNA1 plasmid vector
b. It is correct. The homology-directed repair (HDR) fragment of interest enters into the cell and is then inserted at the site of the original double-strand breaks (DSBs) via the HR DSB repair pathway.
c. plasmid, nucleus, cytoplasm
d. Once Cas9 is transcribed, this nuclease forms a complex with the gRNA and cuts the target DNA, thereby inducing a DNA double-strand break (DSB) which is repaired either by non-homologous end joining (NHEJ) or homology-directed repair (HDR)
Explanation:
The clustered regularly interspaced short palindromic repeats (CRISPR)-Cas (i.e., CRISPR-associated protein 9) is a natural prokaryotic defense mechanism against foreign viral invaders. In genome engineering, this system has been adapted to create a versatile RNA-programmable genome editing technique. Cas9 is an RNA-guided endonuclease capable of recognizing and cleaving a target DNA complementary to the guide RNA (gRNA). The gRNA is a specific RNA sequence formed by two small RNAs (crRNA and tracrRNA), which binds to the Cas nuclease enzyme and guides the gRNA-Cas9 complex to the target DNA sequence.
Choose the correct problem for the fraction 25/20. 25 x 20 20 ÷ 25 25 ÷ 20 20 ÷ 20
Answer:
25 divided by 20
Explanation:
for example: 1/4 = 1 divided by 4 which is equivalent to 0.25 or 1/2 = 1 divided by 2 which equals 0.5/0.50
these to give you the amount so 1/4 is equivalent to 25% and 1/2 is equivalent to 0.50% of the whole so now if we do 25 divided by 20 it would be equal to 1.25.
which of the following best explains the purpose of photosynthesis?
In photosynthesis, oxygen is used to make sugar.
In photosynthesis, sunlight is used to make ATP
in photosynthesis, sunlight is used to make sure
in photosynthesis glucose is used to make energy
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Answer:
The livestock waste fertilizes the grasses
Explanation:
A negative ecological impact is one that is detrimental to the ecosystem or that results in a disadvantage to organisms in the ecosystem.
When livestock graze on rangelands, it would result in both positive and negative impacts to the rangeland.
Some of the negative impacts includes those listed in the options. For example:
1. The weight of the grazing cattle as they move around to graze will compact the soil. This compaction of the soil will reduce aeration of the soil as well as the fertility of the soil.
2. The livestock may eat too much grass which is known as overgrazing. Overgrazing will not give the plants enough time to regrow before they are eaten. this will eventually result in too few grasses growing in the rangeland.
3. Increased wind and water erosion due to overgrazing. as the livestock graze, they remove grasses which help to reduce wind and water erosion on the soil. This results in loss of soil fertility.
However, an advantage of grazing on the rangeland as the livestock graze is that the wastes of the livestock serves as a source of manure for the grasses which fertilizes the soil and makes the grasses grow.
a. Make a list of as many traits as you can think of that could be used to classify a new species.
b. Which of the traits in the list above would be most useful for classification at high levels (e.g. classifying things into different kingdoms or phyla) , which would be more helpful at lower levels (e.g. family or genus)
Answer:
a. My list is the following:
1. presence of photosynthetic pigments
2. presence of cell wall
3. body symmetry pattern
4. presence of cell nucleus
5. presence of specialized organelles
6. presence of hair
7. presence of mammal glands
8. niche (e.g., terrestrial or marine habitats)
9. diet (food habits)
10. position of a particular muscle
Explanation:
b. In the list above, traits such as the presence of a cell nucleus or specialized organelles can be used to classify organisms at the kingdom level (since these phenotypic features are observed in eukaryotic organisms but not in prokaryotes). In a similar mode, animals may exhibit two different body symmetry patterns: radial (around the central axis) and bilateral (two sides: left and right), thereby symmetry body can be used to classify organisms within the animal kingdom. Other features used to classify species at high levels include the presence of photosynthetic pigments in green plants (chlorophyll) and bacteria (xanthophyll), presence of cell walls in plants (composed of cellulose,) and fungi (composed of chitin), presence of hair and mammal glands (mammals), etc. On the other hand, ecological differences (e.g., food habits, niche) and minor anatomical differences (e.g., the position of a particular muscle) are helpful to classify species at the family/genus level.

he G-protein-linked receptor is located ___________________. When GDP is attached to the G protein the messenger is considered _______. GTP replaces GDP and now the messenger is considered _______. The G protein carrying the GTP leaves the receptor and _______ and enzyme which causes a cellular response. All of this is brought on by a _______ ________ attaching to the G-protein-linked receptor and will shut down quickly when the ___________ ____________ is no longer there.
Answer:
located... on the plasma membrane
is considered... inactive
the messenger is considered... to be active
All of this is brought on by a.... signal molecule
will shut down quickly when the.... signal molecule
Explanation:
The G protein-coupled receptors (GPCRs) are transmembrane proteins found on the plasma membrane. GPCRs are considered to be the most diverse group of transmembrane receptors in eukaryotic cells. These proteins (GPCRs) bind to signaling molecules to trigger signaling pathways through Guanine nucleotide-binding proteins (G-proteins). G proteins are signaling proteins (for example, Ras protein) that bind both GTP and GDP. After the signaling molecule binds to GPCR, GTP is hydrolyzed by the G-protein in a process that triggers specific signaling pathways (for example, activation of the production of second messengers).
Unlike transcriptional termination in prokaryotes, termination in eukaryotes (by RNA polymerase II, anyway): depends on a specific sequence of RNA. depends on a protein, Rat. involves cleavage of the pre-mRNA. involves exonuclease activity. All of the above.
Answer:
involves cleavage of the pre-mRNA
Explanation:
In eukaryotic organisms, the mechanism of transcription termination of protein-coding genes involves two different processes: 1-the site-specific cleavage of the precursor messenger RNA (pre-mRNA) sequence in the 3'-untranslated region (3'-UTR), and 2- the separation of RNA polymerase II (Pol II) from the DNA template. In regard to the cleavage of the pre-mRNA, it is a process followed by the polyadenylation (polyA) of the upstream cleaved product. The main function of the polyA tail is to protect the mRNA from enzymatic degradation. Moreover, the mechanism of transcription termination is accompanied by dephosphorylation of the C-terminal domain (CTD) of the large subunit of the RNA Pol II.

Laura says that wave A has more energy since it is louder, but Jessica disagrees.
Jessica says that wave A is louder, but has the same amount of energy as wave B since
the wavelength is the same. Who is right and why?
O Neither is right because energy depends on the medium that the waves are traveling through.
Jessica is right. Wave A is louder and wave B is softer.
Laura is right because wave A has a higher amplitude and therefore more energy.
Jessica is right because wave A and B both have the same wavelengths.
Answer:
wave A is louder then wave B
how do waves affect landforms
the pressure and the force of waves produce more rocks
pressure and force of ways can break Cliffs Apart
waves can cause rocks to change it what it is made of
Answer:
Waves erode the bedrock along the coast largely by abrasion. The suspended sediment particles in waves, especially pebbles and larger rock debris, have much the same effect on a surface as sandpaper does. Waves have considerable force and so may break up bedrock simply by impact.
Which discovery supported the endosymbiotic theory?
The discovery of independent DNA (from the host) in mitochondria and chloroplasts supports the endosymbiotic theory.
The endosymbiotic theory is the theory that mitochondria and chloroplasts, two important organelles found in eukaryotic cells, originated from bacteria that were engulfed by larger cells.
What is this theory?The presence of DNA in mitochondria and chloroplasts. Mitochondria and chloroplasts have their own DNA, which is separate from the DNA in the nucleus of the cell. This suggests that they were once independent organisms.
The similarity of mitochondrial and chloroplast DNA to bacterial DNA. The DNA in mitochondria and chloroplasts is similar to the DNA of bacteria. This suggests that they share a common ancestor.
The presence of ribosomes in mitochondria and chloroplasts. Mitochondria and chloroplasts have ribosomes, which are structures that are used to make proteins. Ribosomes are also found in bacteria.

Lions and Tigers are the most similar of the "Big Cats". Why are Lions and Tigers so similar?
Big Cats | Big cats art, Wild cats, Big cats
Question 4 options:
because lions and tigers both need to hunt
because lions and tigers have many of the same genes
because lions and tigers have the same type of cells
because lions and tigers share the same organelles
Answer:
B. Because lions and tigers have many of the same genes.
Explanation:
You can rule out A, since all big cats and other predatory animals must hunt to survive.
C can be ruled out, as all animals have roughly the same cells.
D can be ruled out as well, since all animal cells have the same organelles (essentially the same reason C can be ruled out.)
That leaves us with option B. B is the most likely answer, as lions and tigers share most of their DNA with one another.
