Today where can continental glaciers be found in
Answer:
polar regions of Greenland and Antarctica
Explanation:
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).
List four uses of lactic acid fermentation. List four uses of alcoholic fermentation.
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.
Why do kokanee salmon spawn only once?
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.

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.
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.

Flask 1, 2 and 3
O Flask 1 and 3
O Flask 2 and 3
O None
Answer: Flank 1 and 3
Explanation:
The organisms in flask 1 and 3 undergoes cellular respiration.
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.

Describe an adaptation of the bull kelp for gathering sunlight
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.

Answer: Cycling of Matter and Energy Quick Check
1.While detritivores feed on dead organic matter, decomposers actually break down dead or decaying organisms.
2.Food webs are more complex than simple food chains.
3.heterotrophs
4.autotroph
5.Matter and energy are cycled through the ecosystem.
Explanation:
:)
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.
