Answer:
Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.
Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.
Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.
Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.

What makes Protists different from the Bacteria kingdoms?
A. They are easier to find.
B. Their cells have a nucleus.
C. They are bigger.
Answer:
B. Their cells have a nucleus.
Explanation:
The primary difference between them is their cellular organization. Bacteria are single-celled microbes and are prokaryotes, which means they're single-celled organisms lacking specialized organelles. ... In contrast, protists are mostly single-celled eukaryotic organisms that are not plants, fungi, or animals.
Answer:
B. Their cells have a nucleus.
Explanation:
Protists are different from the Bacteria kingdom because, their cells have a nucleus.
Cells created by meiosis can be
represented by which of the following?
A.2B
B.B
C.2N
D.N
Answer:
D. N
Explanation:
Meiosis is a kind of cell division which produces daughter cells that are genetically different from the parent cell and have a reduced number of chromosomes (by half).
Meiosis occurs only in reproductive cells to produce gametes. If a diploid (2n) cell undergoes meiosis, a haploid (n) daughter cell will result. This means that the chromosome number has been reduced by half in order to maintain the chromosomal number of the next generation.
During strenuous exercise, lactic acid fermentation begins because the muscle cells are not getting enough
water
glucose
oxygen
ATP
Answer:
oxygen
Explanation:
Without oxygen aerobic respiration cannot occur. Therefore ATP is produces by anaerobic reparation which is from glycolysis only. Lactate/ lactic acid is formed when glycolysis is the only production of ATP.
A circular ring of DNA that typically exists in bacteria and that codes for certain traits is known as a/n
Answer is Plasmid.
A plasmid is a small, circular, double-stranded DNA molecule that is distinct from a cell's chromosomal DNA. Plasmids naturally exist in bacterial cells, and they also occur in some eukaryotes. Often, the genes carried in plasmids provide bacteria with genetic advantages, such as antibiotic resistance.
how does natural selection impact the way a population adapts?
Answer:
The organisms with the more desirable traits will survive and pass on their genes.
Explanation:
"Natural selection" is pretty much "survival of the fittest." This means that the organisms who have a better chance of surviving and reproducing will control the way a species adapts. For example, there may be a mutation in a species of moths that make their wings more brown instead of yellow (just threw a random color out there). Well, the moths born with the mutation that turns their wings brown will likely live longer and be able to reproduce more because they can blend in with their environment better. So, as a result, their mutation can get passed on and the species will adapt to have more moths with brown wings.
3) In order for an ecosystem to thrive, it needs to exist in a form of harmony and balance between its biotic and abiotic factors. Describe how small changes to both biotic and abiotic components can have major effects on an ecosystem.
Answer:
Changing temperature causes extinction or removal of organism from that place.
Explanation:
Small changes to both biotic and abiotic components can have major effects on an ecosystem because these are the factors on which the ecosystem depends. For example, if the temperature of the ecosystem increases from its limit, it makes the environment unfavourable for the organism so due to this change, the organism migrated to other location otherwise they will die due to unfavourable environment.

Answer:
They are elaborate network of channels running through the cytoplasm. There are two types of endoplasmic reticulum. They are; Rough and smooth endoplasmic reticulum. Rough endoplasmic reticulum are rough because of the presence of ribosomes. Smooth endoplasmic reticulum are smooth because they dont have ribosomes.
meaning:an extensive intracellular membrane system whose functions include synthesis and transport of lipids and, in regions where ribosomes are attached, of proteins
Study the diagram of gametogenesis where egg cells and sperm cells
undergo meiosis I and meiosis II. Note the number assigned to each cell.
Identify the number of chromosomes in the different cells, represented
by a circle, by writing the symbol N for haploid and 2N for the diploid.
Write your answers on a separate sheet of paper.
A diploid cell undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.
What happen during the egg formation?During egg formation in the ovary, Primary oocyte (diploid) having 46 chromosomes undergoes meiosis I to form one secondary oocyte and one first polar body.
Both the secondary oocyte and one polar body are haploid having 23 chromosomes. Both daughter cells then undergo meiosis II, the first polar body divides to give two polar bodies and the secondary oocyte divides by meiosis II to form one ovum.
Therefore, during egg formation in the reproductive system, a diploid cell (a primary oocyte) undergoes meiosis to produce one egg and 3 polar bodies with 23 chromosomes each.

Read the following selection and answer the question. On a September day in 1999, people began to notice that Lake Jackson in the Panhandle region of northern Florida was shrinking. Within a few days, it was almost gone. A sinkhole had opened beneath the lake and drained it, along with all of its inhabitants including fish and alligators. As aquifers lose water, rock and soil layers can become weaker and less capable of supporting overlying layers of earth and any human structures built upon them. In such cases, the land surface above may subside, or sink. Sometimes subsidence can occur locally and suddenly in the form of sinkholes, which are areas where the ground gives way with little warning. Once the ground subsides, soil becomes compacted, losing the porosity that enabled it to hold water. Recharging a depleted aquifer may therefore become more difficult. Sinkholes occur when?
Answer:
Sinkholes occur when water from the groundwater has been removed in excess.
Explanation:
Sinkholes are empty spaces in the ground that occur due to the landslide of large volumes of land, creating craters of different sizes. This landslide takes with it everything that is on top of it, such as houses, animals, streets and even entire buildings. While these holes can occur due to engineering flaws, the most common reason is the excessive use of groundwater, which creates an empty space in the interior of the soil and causes the earth to sag.

how might a country run out of water
Answer
Along with decreasing rainfall comes rising temperatures. By 2050 the U.S. could be as much as 5.7°F warmer, and extreme weather events, such as heatwaves and drought, could be more intense and occur more frequently. As temperatures warm, evaporation increases, further decreasing water in lakes, reservoirs, and rivers.

Need help asap just answer write the article the first 1 i already answered just copy pasted the questions
Answer:
We got a chance to speak to Noah the Ark builder. Many people of the town have been wondering what Noah has been building lately. We asked him what was his objective and he said "A great flood like no other will come, water from the sea will fall from the air. Whoever is in the ark shall be safe. Two of each type of animal on earth shall come to my ark for shelter. The storm will be so great it will knock out all who does not inhabit the ark."It is hard to understand what he means by these statements but who knows maybe his boat will take him somewhere. The people of the town have been calling him insane, since no one would need a boat that big.
(I'm guessing that you mean the interview was before the flood since everyone died after.)
