Hello! Can someone explain Pollen Tube Germination to me?
Answer:
At the time of liberation, it becomes 2 celled, with a small generative cell and a vegetative cell. In the nutrient medium, the pollen grain germinates. The tube cell enlarges and comes out of the pollen grain through one of the germ pores to form a pollen tube. The tube nucleus descends to the tip of the pollen tube.
Explanation:
A high abundance of nutrients can cause which of the following? A.) heavy rainfall B.) an increase of crop production C.) aggressive competition between producers
Answer:
B) an increase of crop production

21. Which stage of aerobic respiration produces ATP and NADH and release CO2?
a Glycolysis
b. Krebs cycle
c Electron transport chain
d. Fermentation
stage of aerobic respiration produces ATP and NADH and releases CO2, which is the electron transport chain that is in option c, as the ETC has a role in the production of ATP in cellular respiration.
What is the significance of respiration in ATP synthesis?It plays an important role in respiration because it is formed by the oxidation of glucose or other organic molecules in the mitochondria of eukaryotic cells and in the cytoplasm. During respiration, glucose and oxygen are consumed, and carbon dioxide and water are produced, and then the mitochondria make ATP by taking the products of glucose.
Hence, aerobic respiration produces ATP and NADH and releases CO2, which is the electron transport chain that is in option c, as the ETC has a role in the production of ATP in cellular respiration.

Which statement about active transport is most accurate? Active transport utilizes energy from ATP molecules. Active transport utilizes energy from ATP molecules. Active transport is essential to move water into and out of a cell. Active transport is essential to move water into and out of a cell. Active transport is the only way to move ions into and out of a cell. Active transport is the only way to move ions into and out of a cell. Active transport is required to move ions into and out of a cell. Active transport is required to move ions into and out of a cell.
Answer:
I feel like you just answered your own question but I'm going to help you out anyway, active transport utilizes energy from ATP molecules.
Explanation:
The most accurate statement about active transport is active transport utilizes energy from ATP molecules.
Transport active is a type of transport used by cells to move substances against a concentration gradient across cell membranes.Active transport Is mediated by different membrane proteins known as carrier proteins coupled to an energy source such as, for example, ATP.During this process (active transport), hydrolysis of ATP provides the energy required to move molecules/ions against a concentration gradient.In conclusion, the most accurate statement about active transport is active transport utilizes energy from ATP molecules.

How does the human body obtain glucose? For BIOLOGY exam.
Answer:
When the stomach digests food, the carbohydrate (sugars and starches) in the food breaks down into another type of sugar, called glucose. The stomach and small intestines absorb the glucose and then release it into the bloodstream.
Which types of species tend to dominate river ecosystems? How do conditions between fast-moving 'headwaters' (or sources) of rivers differ from slow-moving 'mouths' of rivers? Where are the majority of producers in a lake located? Where would you expect to find the largest food webs - oligotrophic, mesotrophic, or eutrophic lakes? Explain. What characteristic defines a wetlands? Why are wetlands so ecologically productive, and what valuable ecosystem services do they provide to humans? Where are coral reefs generally found, how are they built, and why are they under heavy threat from bleaching? Do the vast open oceans areas deeper than ~200 meters and away from coastlines support much life? Explain
Answers with Explanation:
Q1) In faster moving rivers, salmon species dominate. In slower moving rivers, catfish dominate.
Q2) Fast moving rivers have high oxygen levels due to the rapid mixture of water and air. Slow moving rivers experience less mixing of air and water, decreasing their oxygen levels.
Q3) The majority of producers are found at the littoral zone. This is because it is shallow and allows easy penetration of light for photosynthesis.
Q4) Eutrophic lakes, this is due to their high level of productivity.
Q5) The wetlands are biomes that are submerged or saturated by water for at least part of each year, but shallow enough to support vegetation.
Q6) The wetlands are ecologically effective as they take in large amounts of rainwater and release it slowly, helps to prevent droughts , filter pollutants, and recharge the ground with clean water.
Q7) The coral reefs are found in warm, shallow waters beyond the shoreline. They're built by secreting a layer of limestone to form their external skeleton. They're under heavy threat of bleaching due to lower ocean pH and higher water temperatures.
Q8) The vast open oceans areas deeper than 200 meters and away from coastlines doesn't support much life due to decrease in light intensity for photosynthesis and oxygen levels. These zones includes: mesopelagic zone, bathypelagic zone and abyssal zone.

Why is it difficult for your body to return blood from your feet when you sit for too long?. Single choice. a. Blood has to travel a greater distance. B. Skeletal muscles are not squeezing the veins. c. Gravity makes the blood flow backward. d. The heart does not beat fast enough at rest.
Answer: Option C.
Gravity makes the blood flow backward
Explanation:
it difficult for your body to return blood from your feet when you sit for too long because gravity makes blood flow backward and this is because when you sit for long , it weakens the keg muscles because it is necessary for body movement so that blood will circulate or flow well. When the keg muscles becomes weak, it will slow blood flow in the leg and the force of gravity acting will make the blood flow backward and thus can cause a blood clot.
