Describe how flowering plants reproduce.
Answer:
Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.

In the hierarchy of organisms, the ecosystem
level is the first that includes which of the
following?
A. biotic factors
B. abiotic factors
C. niches
Answer:
B
Explanation:
In the hierarchy of organisms, the ecosystem level is the first that includes abiotic factors. The correct option is B.
What is a hierarchy of organisms?
The systemic classification of organisms into levels, such as the Linnaean taxonomy, is referred to as biological hierarchy (a biological classification set up by Carl Linnaeus).
It arranges living things into kingdoms, phyla, classes, orders, families, genus, and species in order of decreasing complexity. The eight levels of the present taxonomic hierarchy, from lowest to highest, are as follows: species, genus, family, order, class, phylum, kingdom, and domain.
A multicellular organism's body is organized at many levels, beginning with the cell. Organs are formed from tissues, which are composed of cells. Organs are arranged into organ systems, and then an organism is formed.
Therefore, the correct option is B. abiotic factors.

What is the effect of climate change on polar regions?Climate change causes melting of ice caps in colder regions where polar bears live. This change has made it harder for polar bears to successfully hunt seals. This situation will lead to extinction of polar bears in this location because they can't get their food which leads to their death.
So we can conclude that extinction occurs due to the climate change in the polar regions of the earth.

an engine cut-off lanyard helps to reduce the risk of what?
An engine cut-off lanyard helps to reduce the risk of striking a person in the water with a propeller. The correct answer is option 2.
A propeller is a device with rotating blades that is used to propel a vehicle through a fluid, such as air or water. In the context of boating, a propeller is a rotating device that is attached to an engine and used to propel a boat through the water.
An engine cut-off lanyard is a safety device that is attached to the operator of a boat and to the engine's kill switch. If the operator is thrown from the boat, the lanyard will pull the kill switch, stopping the engine and preventing the propeller from causing injury to the operator or others in the water.
Therefore, an engine cut-off lanyard is an important safety feature that can help prevent accidents and injuries on the water. Option 2 is the correct answer.

3. What is the difference between saponifiable and nonsaponifiable lipids?
Answer:
the difference is that unsaponifiable lipids do not contain fatty acids at least not as a component of the fundamental structure whereas saponifiable lipids do have fatty acids.
Explanation:
As a further explanation unsaponifiable lipids are lipids that do not contain fatty acids as components of the fundamental structure. On the other hand, complex also known as saponifiable lipids do contain fatty acids, and those fatty acids can be released in a process called saponification which is caused by alkaline hydrolysis.

Which result would be expected from comparing ATP yield in cellular respiration in plants and animal cells?
There would be no difference
There would be 50% more in plant cells
There would be 25% more in animal cells
O Plant cells make 38 ATP for every 4 ATP made by animal cells
The result that will be expected from comparing ATP yield in cellular respiration in plants and animal cells is : ( B ) There would be 50% more in plants cells
Difference between ATP yield in plant and animal cellsATP is produced in the mitochondria during cellular respiration of plant and animal cells. Given that plants possess chloroplast which performs photosynthesis, this helps with an increase in the ATP yield in plant cells.
Therefore the 50% more of ATP yield will be present in plant cells when compared to ATP yield in animal cells.

Explain the DNA Replication diagram above with all the great terms from this chapter. This is a BIG ANSWER.
DNA replication or duplication is the process of making copies of DNA by the cell. It involves a series of steps and various enzymes required for the completion of the process.
What is the process of DNA replication?DNA replication has several steps along with some proteins called replication enzymes as well as RNA.
The process of replication is as follows:
Replication fork: It is made by unzipping DNA into two strands. It is done by break of the purine and pyrimidine bond accomplished by an enzyme called DNA helicase.Primer binding: After this unzipping, a short piece of RNA which is called as a primer binds to the 3' end of the DNA strand. The primer bound is the starting point for replication. Primers are generated by the enzyme referred to as DNA primase.Elongation: DNA polymerase aids in the elongation process in DNA replication. As the replication moves in the 5' to 3' direction on the leading strand, the newly formed strand will be continuous. But in the case of the lagging strand replication starts by binding with multiple primers which involve DNA polymerase and then adds pieces of DNA, called Okazaki fragments, to the strand between primers. Termination: On the formation of both the strands, Exonuclease removes all RNA primers followed by proofreading and then the adhesion of the Okazaki fragments by enzyme DNA ligase.Thus, these were the steps involved in the process of DNA replication.
