The vertebrate lung first appeared in ___________.
Answer:
fishes
Explanation:
A progenitor feature found in early boney fish served as the basis for the development of the vertebrate lung.
What are vertebrate lungs?The lung of modern vertebrates evolved from a structure that was present in the ancestors of early boney fish.
Lungs in vertebrates originated as extra air-breathing organs in primordial fishes and were ventilated by buccal pumping when they first appeared. In more modern fishes, the organ formerly known as the lungs has been replaced with the hydrostatic swimbladder. This fundamental kind of unicameral lungs and the buccal pumping ventilation observed in these lungs can also be found in more modern amphibians.

Identify the RNA bases that would pair up with the DNA sequence TGCACT
A. TGCACT
B. ACGTGA
C. UCGUGA
D. ACGUGA
RNA and DNA are two nucleic acids that differ in nitrogen bases. ACGUGA is the RNA base pair that will pair with TGCACT, of DNA. Thus, option D is correct.
What is complementary base pairing?The complementary base pairing has been defined as the pairing of the nucleotides with each other to form the RNA or DNA structures. The base pairs with each other through hydrogen bonding where the reaction occurs between the purines and pyrimidines.
The RNA and DNA structure differs as RNA is made of ribonucleic acid with four nitrogen bases, A, U, G, and C, whereas DNA is made of deoxyribonucleic acid with bases, A, T, G, and C. Both differ in sugar and one nitrogenous base.
According to Chargaff's base pairing rule the purines (adenine and guanine) pair with pyrimidines (cytosine, thymine, and uracil). A forms a double bond with T in DNA and U in RNA, and G forms triple bonds with C.
The given DNA sequence is: TGCACT
The RNA bases for the sequence will be: ACGUGA
Therefore, option D. ACGUGA is the complementary base pair.

If you are experiencing Na channels deactivating the plasma membrane which hyperpolarizes the membrane which sense is being activated?
The options are missing from the question,below are the options.
A) touch
B) smell
C) hearing
D) sight
The correct answer to the question is option D
SIGHT.
If one is experiencing Na channels deactivating the plasma membrane,the sense that is being activated is SIGHT,
this is because in the red blood cell,the light induced isomerization of the moiety retinal rhodoesin produce activated opsin which goes ahead to activate the signal transducing G-protein transducin,this it does by catalyzing exchange of GTP (Guanosine triphosphate) for bound GDP(guanosine diphosphate) on the subunit.
This GTP in turn activates the level of CGMP (Cyclic guanosine monophosphate) phosphodiesterase and it further acts to lower the level of CGMP.
Upon this reduction,it leads to the closing of CGMP-gated Na+ channels and hyperpolarization of the membrane.

Explanation:
Shifting biomes could have consequences for the regions in which the shifts occur. Read the two cases below and decide which consequences would apply to one or both cases.Case 1: The biome of a small agricultural community in the western United States changes from grassland to desert. A species of migrating duck, which can carry bird flu, goes locally extinct.Case 2: The biome in northern Russia changes from tundra to taiga. Timber harvesting in the region becomes possible. Arctic foxes go locally extinct and are replaced by red foxes that commonly carry rabies.Sort each consequence based on whether it would apply to Case 1, Case 2, or botha. increased risk of wildfiresb. local economy suffersc. carbon storage decreasesd. agricultural production decreasese. carbon storage increasesf. disease vector range changesg. decreased water availabilityh. local economy thrivesi. species range changesCase 1Case 2Cases 1 and 2
Answer:
increased risk of wildfires- both
local economy suffers- Case 1
carbon storage decreases - Case 2
agricultural production decreases - Case 1
carbon storage increases - Case 1
disease vector range changes - Case 2
decreased water availability - Case 1
local economy thrives - Case 2
species range changes - Case 2
Explanation:
Fires are common to taiga biomes. Owing to the fact that the biome in case 1 changed from an agricultural community to a grassland and subsequently to a desert, agricultural productivity will decrease, the local economy will suffer, water availability is decreased and local economy suffers as a consequence of desertification.
On the other hand, in case 2, the diseases vector range as well as species range changes due to the change in the species of foxes from Artic foxes to red foxes that carry rabies. Carbon storage decreases as the taiga biome acts as a carbon sink. The local economy thrives due to timber production.
Lastly, species range changes both in case 1 and case 2 since there is a loss of species. Species range is the area where a particular species can be found during its lifetime. Certainly, the range of area where species are found changed in cases 1 and 2.
The consequences from the given cases are sorted as:
case 1: b. the local economy, c. carbon storage decreases, d. agricultural production decreases, f. disease vector range changes, i. species range changes, g. decreased water availability
Case 2: a. increased risk of wildfires, e. carbon storage increases, f. disease vector range changes, i. species range changes, h. the local economy thrives
Case 1 and 2 both: f. disease vector range changes, i. species range changes.
Consequences by shifting biomes?Case 1:
The shifting of biome from the agricultural community in the United States changes from grassland to desert result in consequences like decrease in the carbon storage and local economy suffers because of reduction in the agricultural production.
Also since the biome changes to the desert, it results in decreased water availability. Also since the biome changes, a species of migrating duck that carries flu goes locally extinct which implies that there will be a change in the range of species as well as the disease vector changes.
Case 2:
Since the biome in Russia changes from Tundra to Taiga now harvesting becomes possible and due to which carbon storage increases which in turn results in the flourishing of the local economy.
As an increase in the forests, there will be an increased risk of wildfires. Since the c foxes go locally extinct and are replaced by red foxes which carry rabies which implies that species range changes and the disease vector range changes.

What foods below would test positive for starch in the presence of iodine?
Question 8 options:
a steak
a hard boiled egg
noodles, bread, or crackers
chicken
The group of foods that would test positive for starch in the presence of iodine would be noodles, bread, or crackers.
Noodles, bread, or crackers consist largely of starch. Starch has the capacity to turn the brown color of iodine to blue-black because the iodine molecules insert themselves in the structure of the amylose content of the starch.
Foods like steaks, hard-boiled eggs, and chicken are essentially made of proteins and will, therefore, fail the iodine test for starch.

A plant is the most balanced need for water within its need for carbon dioxide and oxygen. It’s too much water is lost, the stomata will close. How does this affect the plants ability to regulate levels of carbon dioxide and oxygen?
Answer:
it helps regulate them and keep them level going through the state of transpiration
Explanation:
to prevent too much water lost a plant will close it's stoma to store that water, this process is called transpriation. if the stoma is open it will dry out the plant.
so a plant losing water in reaction they will close their stoma which is homeostasis, homeostasis is balance. so for example u go through homeostasis when it's hot outside it results in u sweating, why? cause your body is trying to cool down and regulate it's self.

a group of students found the specific gravity of a pice of galena to be 7.8. The accepted value for the specific gravity of galena is 7.2 find the % of error in the student's work
Answer:
Percent error = 8.3%
Explanation:
Given data:
Accepted value of specific gravity = 7.2
Measured value of specific gravity = 7.8
Percent error = ?
Solution:
Percent error = measured value - accepted value / accepted value × 100
Now we will put the values in formula.
Percent error = 7.8 - 7.2/7.2 × 100
Percent error = 0.6/7.2 × 100
Percent error = 0.083 × 100
Percent error = 8.3%
