list three reasons why phytoplankton cannot survive at a hydrothermal vent
Answer:
1. phytoplankton and other organisms harness sunlight , to create photosynthesis , near hydrothermal vent there is no sunlight
2. Phytoplankton need nutrients to grow, so when there's none at the surface they can't thrive, and there's no surface in hydrothermal vent
3. The ocean's increasing acidity will most likely kill them.
Hope that helps
Explanation:
Algae called phytoplankton need sunshine to perform photosynthesis.Additionally, they need particular minerals like nitrates, phosphates, and silicates, which come from the upwelling of nutrient-rich deep waters.The varying of the seasons has an impact on both of these variables.
Why are phytoplankton cells found close to the ocean's surface?
Similar to plants on land, phytoplankton use photosynthesis to absorb energy from the sun's rays, turn it into fuel, and make oxygen from carbon dioxide.Phytoplankton are found close to the water's surface since they require the sun's energy. Similar to terrestrial plants, phytoplankton uses photosynthesis to convert solar energy into chemical energy by using chlorophyll to absorb light.They exhale oxygen while consuming carbon dioxide. Photosynthesis, the process of generating energy from chlorophyll and sunlight, is how phytoplankton obtains its energy.Phytoplankton absorb carbon dioxide and expel oxygen, just like other plants. The winter phytoplankton blooms are caused by the northeast monsoon's upwelling of subsurface water rich in nutrients to the surface layer. The phytoplankton is then moved northward by the surface flow, which displaces the center of the bloom from the upwelling centerFor photosynthesis, phytoplankton needs sunshine in addition to nutrients and a suitable environment.Only the topmost ocean layers, known as the epipelagic or euphotic zone, allow light to pass through.Few phytoplankton below this zone receive the requisite sunlight for photosynthesis.To learn more about phytoplankton refer

Answer:
The correct answer is - C. protein - Millons' test - red precipitate is formed.
Explanation:
The iodine test is the test that is used for the identification or presence of the starch in a food sample, in this test if starch present in the food then the solution of iodine and KI will turn to deep blue color. Therefore the given result is incorrect
The benedict test for confirming if glucose present in the sample, it is a mixture of sodium carbonate, sodium citrate, and copper(II) sulfate pentahydrate which starts as aqua blue in color but after adding sample and gradually heating it turns from yellow to orange as per the concentration of the glucose. Thus, it is incorrect.
The emulsion test also produces the milky precipitate or emulsion in presence of fat or lipid in the sample. so, it is incorrect.
Millon's test for protein is the test that results in the red solution or red precipitate in the presence of the protein in the sample.

make a list of all the non photosynthetic parts of a plant that need a supply of sucrose and amino acids
Answer:
The non-photosynthetic parts of the plant include any parts that lack chlorophyll, such as the roots, woody stems, fruits, and seeds. These parts of the plant do not contain chlorophyll, and thus are unable to capture light energy from the Sun. They rely on photosynthetic parts of the plant, such as the leaves and parts of the stem to do photosynthesis. In vascular plants, the nutrients produced during photosynthesis are transported to non-photosynthetic parts of the plant through the phloem. Phloem is a vascular tissue designed to transport glucose and other nutrients produced during photosynthesis to parts of the plant that are non-photosynthetic, such as the roots.

The process by which a cell copies its DNA before it divides is
1.
mutation
2.
diffusion
3.
replication
4.
respiration
Answer:
Replication
Explanation:
Replication is the process of making copies of dna
It's obviously not respiration or diffusion, they are both completely different processes that have nothing to do with cell division
Mutation is also the wrong answer because it's a process that results a new/different type of dna

if someone sitting at the other end of a restaurant smokes a cigarette, you may still breathe some in some of the smoke. The movement of smoke through the air of the restaurant is an example of what type of transport?
a. osmosis
b. diffusion
c. facilitated diffusion
d. active transport
Answer:
C.facilitated diffusion
Explanation:
Because it have some chemicals did you breathe from the person who using cigarettes.
You may still breathe some of the smoke in because The movement of smoke through air is an example of ; (b) diffusion
Diffusion is the movement of airborne particles/substances across ( the restaurant air ) from a region of with high concentration to an area experiencing a lower concentration.
The diffusion of the smoke from the cigarette with some chemicals contained in it from the smoker to the region where you breathe in some of the smoke. is an example of diffusion
Hence we can conclude that the movement of smoke through air is an example of diffusion.
