Answer:
Summary. Species interactions within ecological webs include four main types of two-way interactions: mutualism, commensalism, competition, and predation (which includes herbivory and parasitism). Because of the many linkages among species within a food web, changes to one species can have far-reaching effects.

1. According to Model 1, in what type of organs are the cells that enter meiosis I found? 2. Considering what you already know about mitosis in cells, what event must take place during interphase before a cell proceeds to division? 3. What two structures make up a single replicated chromosome? 4. In Model 1, how many replicated chromosomes does the cell contain during prophase? 5. At which stage in meiosis I do the pairs of homologous chromosomes come together? 6. Once the chromosomes have formed a pair, what are they called?
Answer:
1.) Sex organs
2.) DNA replication
3.) Sister chromatids
4.) Two identical daughter cells
5.) Late prophase 1
6.) Tetrads
Explanation:
Meiosis is a type of cell division that occurs in living organisms which involves the division of a single cell to produce four cells containing half the original amount of the parent genetic information. An example of organs that enter meiosis is the SEX CELLS.
Mitosis is another type of cell division that leads to the production of two daughter cells which are genetically identical to the parent cell. During interphase before a cell proceeds to division, DNA replication must occur. This is a process DNA uses to make a copy of itself during cell division.
Chromosomes are genetic material which occurs in pairs known as the SISTER CHROMATIDS
PROPHASE in the stage the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells
During late prophase 1 the pairs of homologous chromosomes come together to form two chromosomes and four chromatids, with one chromosome originating from each parent.
Once the chromosomes have formed a pair they are called TETRADS

Which of the following statements best explains why evolution by natural selection is considered a theory and not a hypothesis?
Natural selection provides the outline of an explanatory theory." Biologists consider it to be a scientific fact that evolution has occurred in that modern organisms differ from past forms, and evolution is still occurring with discernible differences between organisms and their descendants.

8. Ice erodes rock and deposits sediments to form
Answer:
glacial landforms
Explanation:
Glaciers cause erosion by plucking and abrasion. Glaciers deposit their sediment when they melt. Landforms deposited by glaciers include drumlins, kettle lakes, and eskers.
Answer:
Erosion and Deposition by Ice Key Concept Glaciers shape Earth’s surface by moving rock and sediment. What You Will Learn • As glaciers move, they form a variety of landforms by removing rock and soil. • Glaciers deposit rock material when they melt or retreat. Why It Matters Glaciers have formed many of the landforms on Earth.

examples.
Answer:producers are organisms that make their own food. Producers create food for themselves and also provide energy for the rest of the ecosystem. Any green plant, like a tree or grass, as well as algae and chemosynthetic bacteria, can be producers. Consumers are organisms that need to eat to obtain energy.

Explain how the fossil described above supports the idea of plate tectonics?
Answer:
Modern continents hold clues to their distant past. Evidence from fossils, glaciers, and complementary coastlines helps reveal how the plates once fit together.
This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.
Fossils tell us when and where plants and animals once existed. Some life "rode" on diverging plates, became isolated, and evolved into new species. Other life dispersed to new areas as continents reconnected, oceans narrowed, or chains of volcanic islands formed. Finding identical or similar fossils in areas separated by vast distances were some of the first clues that scientists used to reconstruct past plate movement. This distribution of fossils led to theories that the southern continents were once joined in a supercontinent called Gondwana.
Explain why it is necessary that gametes (egg cells and sperm cells) have half the DNA that normal body cells have.
Answer:Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

HURRYYYY PLEASEEEEEE FASTTTT
which trait is considered dominant?
The trait that is hidden or covered up by the recessive trait.
The trait that is the most specific.
The trait that masks or covers up another trait and appears
any time its allele is present at least once in the gene pair.
The largest trait someone can have.
Answer:
D. The largest trait someone can have
Explanation:
This option makes the most sense to me because the dominant trait is the largest trait you can have, that is used the most often in your genetic code.

Explain how the speed of light changes between a gas liquid and solid
Answer:
As a rule sound travels slowest through gases, faster through liquids, and fastest through solids. The speed of light as it travels through air and space is much faster than that of sound; it travels at 300 million meters per second or 273,400 miles per hour.
imagine what happens if materials are not send out of the body from time to time ?
Explanation:
excretory system is present in human body which discharge out the waste material time to time. basically when a cell in a body breaks down they produce various waste material like carbohydrates eliminates carbon dioxide while digestive system eliminates through feces. any malfunctioning can cause serious problem like constipitation kidney failure and kidney stones

Cells can be classified into two different categories: prokaryotic and
eukaryotic. Which of the following information is needed in order to
determine if an organism is prokaryotic?
Answer:
Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.
How do plants and humans help each other out?
Answer:
Photosynthesis and respiration are the two essential processes that allow life to sustain on earth. In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants "breathe" by providing them with carbon dioxide.

thrombocytes are essential for coagulation of blood comment
Answer:
Thrombocytes. Thrombocytes (platelets) play an important role in hemostasis, by plugging and repairing damaged blood vessels, thus preventing blood loss. They also participate in a cascade of events that leads to blood clotting by triggering the release of a series of coagulation factors
Answer:
Blood is a connective tissue.it has many cellular components.Thromobocytes or platelets are one of theme.<br> Thrombocytes of platelets are found in blood .There number in the blood is 250000 /cubic mL of blood .They are formed in bone marrow and their life span is one week <br> When an injuiry is caused in the blood vessele,bleeding starts ,and the platelets are disingrated to release the clotting factor 3 called thromboplastin .This in presence of
Ca2+
ions activats prothrombokinase.A series of reaction ultimately occurs which causes blood to clot and plugg the injured blood vessel thus preventing further loss of blood
