can you explain to me what the answer is
Answers
Answer:
D. Lungs
Explanation:
Just from reading this question, I was able to gather that the answer would be Lungs because it is the one body part that would allow amphibians to survive on land. If they just had gills, they would not be able to survive on land because the gills would always require water. Most amphibians do not have fins, and they (particularly frogs) lose their tails after they grow to be adults. So, that is why my answer would be lungs.

:)
The first trophic level in every ecosystem is autotroph.
WHAT IS TROPHIC LEVEL:Trophic level is the position of an organism in the flow of energy within an ecosystem. In an ecosystem, energy flow begins with a set of organisms called producers or autotrophs. Examples of autotrophs are green plants, algae etc.Therefore, the first trophic level in every ecosystem is autotroph.

What is cellular respiration?Cellular respiration is the process by which biological fuels are oxidized in the presence of an inorganic electron acceptor such as oxygen to produce large amounts of energy, to drive the bulk production of ATP.
Cellular respiration is the process that occurs in the mitochondria of organisms (animals and plants) to break down sugar in the presence of oxygen to release energy in the form of ATP.
Cellular respiration is used to generate usable ATP energy in order to support many other reactions in the body.

List four uses of lactic acid fermentation. List four uses of alcoholic fermentation.
Answers
Answer:
The most commercially important genus of lactic acid-fermenting bacteria is Lactobacillus, though other bacteria and even yeast are sometimes used. Two of the most common applications of lactic acid fermentation are in the production of yogurt and sauerkraut.
Lactic acid fermentation happens in our muscle cells when we are exercising feverishly, while alcoholic fermentation is used in yeast cells and is what leads to beer, bread, and wine.

Describe an adaptation of the bull kelp for gathering sunlight
Answers
Answer:
They have gas filled bulbs in order to stay at the top of the water
Explanation:
hope it helps
Bull kelp has evolved to capture sunlight because they have gas-filled bulbs that allow them to float at the surface of the ocean.
What are Bull kelps?Bull kelp is an annual seaweed, meaning it takes a year to develop from a spore to maturity. It can grow by as much as 10 inches (25.4 cm) in a single day. Bull kelp produces spores in reproductive patches (sori), which are mature enough to fall to the ocean floor.
Bull kelp was particularly useful for making lines for fishing nets, harpoons, and anchors. Dogfish oil, saltwater, and freshwater were used to cure the solid portion of the stipe (the stem portion) close to the bottom, sometimes for as long as a year. Because bull kelp can float at the ocean's surface thanks to gas-filled bulbs, they have developed to absorb sunlight.
Thus, Bull kelp has evolved to capture sunlight because they have gas-filled bulbs that allow them to float at the surface of the ocean.

In humans blood type is determined by the A B, and O alleles. The A and B alleles are codominant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes?
A. O only
B.A or B only
C A, B, or O only
D.A, B, AB, оr O
Answers
Answer:
d. A, B, AB, or O
Explanation:
The parent genotypes are AO and BO. Make a punnett square to see the genotypes of the offspring. I tried to make an example one below, but I suggest you draw one out for yourself.
A O
B AB BO
O AO OO
The four genotypes would be AB, BO, AO, and OO. Because A and B are dominant over the O allele, the phenotypes would just simply AB, B, A, and O.
When An individual with the AO genotype and an individual with the BO genotype can produce offspring so the phenotypes should be A, B, AB, or O.
What is Alleles?It is considered as the two or more genes that are available on the same locus of the chromosome.
Since
A and B are codominant genes.
O is a dominant gene, which can be masked by A and B alleles.
So here The genotype of the offspring can be A, B, AB, or O. It is because of the co-dominance of alleles.
Therefore, the option d is correct.

The glaciers of the Antarctic and Greenland ice sheets cannot be spoken of differently than mountain glaciers, as they form ice plateaus that rise high up to 4000 m (with individual peaks up to 5140 m) in Antarctica and 3700 m in Greenland, where the ice overlaps with plateaus and mountain ranges. Antarctic ice cover reaches a thickness of over 4300 m (average 1720 m), Greenland 3400 m (average 2300 m).

It is determined that Elsa is experiencing beta-thalassemia major. Which of the following statements is not true regarding this diagnosis?
A) The cause of beta-thalassemia is genetic.
B) Beta-thalassemia major is a grave condition and has a high mortality rate.
C) Beta-thalassemia major is often treated with blood transfusions.
D) Because beta-thalassemia is an x-linked trait, it affects males more often than females.
Answers
Answer:
The correct option is D
Explanation:
Beta-thalassemia major is a hereditary disorder that usually causes severe anaemia. This mutation/disorder eventually leads to death if untreated especially during in the first two years of infancy. The treatment usually involves the transfusion of blood to clear the phenotypic blockage caused by the mutation. However, it requires both alleles to have the thalessemia mutation for a patient to be said to have beta-thalassemia major. Hence, it is not true that it involves just the x allele and thus affects males more often than females.

Answers
Answer:
TCA
Explanation:
Deoxyribonucleic acid (DNA) is a molecule composed of two polynucleotide strands that coil to form a double helix structure. These DNA strands are antiparallel (i.e., they run in opposite directions) and complementary because the nucleotide sequence in one DNA strand determines the sequence in the other DNA strand. According to the base pair rules, Adenine (A) always pairs with thymine (T), and Guanine (G) always pairs with Cytosine (C). Therefore, if a DNA strand has the sequence AGT, then the other DNA strand will have the complementary sequence TCA.

Why do kokanee salmon spawn only once?
Answers
Answer:
A
Explanation:
Constructing passage ways near the dams to allow to salmon to swim around blocked rivers. The construction of dams in rivers has blocked the path of some salmons returning to spawning grounds. The best way to overcome this is to make the passage ways near the dams to allow salmons to swim in areas which have blocked due to dams. So that salmons can returned to the spawning ground and can spawn which leads to increase in their population.
Answer:
Salmon change color to attract a spawning mate. Pacific salmon use all their energy for returning to their home stream, for making eggs, and digging the nest. ... Unlike Pacific salmon, Atlantic salmon do not die after spawning, so adults can repeat the spawning cycle for several years.
