Answer:
Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
Explanation:
Lichens can do photosynthesis in harsh habitats where plants cannot grow, such as on the surface of rocks, where there is no soil and little water. This is possible because
A) lichens have fungal hyphae that are efficient at absorbing water and minerals to support mutualistic cyanobacteria.
B) lichens are ingestive heterotrophs that can obtain ATP from the chemicals in rocks.
C) lichens have extensive, fibrous roots.
D) lichens are exceptionally efficient at capturing light from the sun.
E) lichens are microscopic and require very little in the way of raw materials.
Answer: A. lichens have fungal hyphae that are efficient at absorbing water and minerals to support mutualistic cyanobacteria.
Explanation:
Photosynthesis, is referred to as the process whereby there's transformation of light energy to chemical energy by green plants and some other other organisms.
We should note that for lichens, they can do photosynthesis in harsh habitats such as on the surface of rocks, where there is no soil and little water because they have fungal hyphae that are efficient at absorbing water and minerals to support mutualistic cyanobacteria.
Therefore, the correct option is A.

What regulates the amount of water in paramecium and amoeba?
Answer:
In Amoeba and Paramoecium, osmoregulation occurs through contractile vacoule. Osmoregulation is a phenomenon in which contractile vacuole plays an important role in maintaining the water balance of the cell. Paramoecium contains two contractile vacuoles which have fixed position.

1. Fill in the complementary DNA strand using DNA base pairing rules.
2. Fill in the correct mRNA bases by transcribing the bottom DNA code
3. translate the MRNA codons and find the correct amino acid using the codon table
4. Use the MRNA sequence to find the correct anticodon for the TRNA molecule
Answer:
PART 1: AAAGTTGCTGGTTG
PART 2:UUUCAACGACCAAC
PART 3:
UUU ---> Phe
CAA ---> Gln
CGA ---> Arg
ACC ---> Thr
AAC ---> Asn
PART 4: AAAGUUGCUGGUUG
Explanation:
Hello There!
PART 1: The first thing we want to do is find the complementary base pairs for the given DNA strand
Remember
The base pairs are
Adenine and Thymine
Cytosine and Guanine
The DNA strand given is
TTTCAACGACCAAC
Now we pair each nucleotide with its complementary base pair
T would change to A
A to T
C to G
and G to C
leaving us with
AAAGTTGCTGGTTG
PART 2: Now we want to transcribe the complementary DNA strand
IMPORTANT NOTE: Transcribing is pretty much like the first part, pairing each nucleotide with its complementary base pair except Adenine changes to Uracil not thymine
so adenine (A) changes to uracil (U)
thymine (T) to adenine (A)
guanine (G) to cytosine (C)
cytosine (C) to guanine (G)
AAAGTTGCTGGTTG
*transcribe*
and we're left with
UUUCAACGACCAAC
The next step is to pair the codons to its corresponding amino acid using the codon table provided below
The first thing we want to do is spread the codons out
Remember codons are a set of 3 nucleotides
Codon 1 (UUU) Codon 2 (CAA) Codon 3 (CGA) Codon 4 (ACC) Codon 5 (AAC)
Now we want to match each codon with its corresponding amino acid
Going from inside to outside using each letter we get that
UUU codes for Phe (Phenylalanine)
CAA codes for Gln (Glutamine)
CGA codes for Arg (Arginine)
ACC codes for Thr (Threonine)
AAC codes for Asn (Asparagine)
PART 4 Finally we want to find the anticodon of the mrna
Which is pretty much pairing each nucleotide base with its corresponding pair
Adenine to Uracil
Uracil to Adenine
Cytosine to Guanine
Guanine to Cytosine
So we'd go from UUUCAACGACCAAC to
AAAGUUGCUGGUUG

What role does competition play in the development of adaptations over time? Hint: Hawk
and Owl.
Answer:
Competition can lead animals to form new habits and adaptations they never had before this is all because of the diversity of animals in our environment and their needs to survive. :)
Explanation:
hawks and owls feed on similar prey. To avoid competition, owls have adapted to be nocturnal, hunting only at night, thus avoiding direct competition with the hawk.
