Answer: answer B Mercury

Explanation: Mercury and Venus dont have a natural satellite

Answer:

See the explanation below.

Explanation:

Marinades serve two different functions: as a tenderizer and flavor enhancer.

Depending on the cut and type of meat, it may need a little assistance to bring it to a palatable range of tenderness. Certain plant and fungi enzymes and acids can break down muscle and connective proteins in meats.

As far back as pre-Columbian Mexico, cooks found that wrapping meats in papaya leaves before cooking made for more tender results. The active enzyme in the papaya leaves is papain, now refined from papayas and commercially available. The connective tissue that comes in direct contact with the protein-digesting enzymes gets broken down. These tenderizing enzymes also reduce the capability of the meat to hold its juices, resulting in greater fluid loss and thus drier meat.

Skin color and height are examples of polygenic traits, which means that they are influenced by multiple genes. A polygenic trait is a trait that is controlled by two or more genes, and the effect of each gene is small.

Skin color is determined by the amount and type of pigments, such as melanin, produced in the skin. This polygenic trait is controlled by several genes, each with a small effect on the final outcome. Height is also a polygenic trait, Skin color is influenced by multiple genes and environmental factors. Many genes have been identified that play a role in determining height, but the exact number and Skin color they interact is not yet fully understood. In addition to genetics, environmental factors, such as nutrition and overall health, also play a role in determining polygenic trait an individual's height. Both Skin color and height, are complex traits and can't be determined by a single gene but by a combination of multiple genes and environmental factors.

A loose hypothesis birds evolved suggests that the ancestors of birds probably ran and jumped to catch prey, and evolved flight to improve on this and return safely to the ground.

Birds evolved from theropod dinosaurs in the Jurassic period (about 165-150 million years ago), and their classic small, light, feathered, and winged body shape was not a spurt of innovation, but rather Gradually assembled over tens of millions of years of evolution. Modern birds descended from a group of two-legged dinosaurs known as theropods, including the towering Tyrannosaurus Rex and the smaller Velociraptor. Some of the similarities between birds and humans are because they shared a common ancestor millions of years ago. This ancestor was a primitive reptilian creature that resembled neither humans nor birds, but shared features of both.

The organ the tissue sample was collected from is a reproductive organ such as testes or ovary.

Metaphase is a stage of mitosis and meiosis, that follows prophase and comes before anaphase, during which condensed chromosomes become aligned before being separated.

Metaphase occurs once in mitosis but occurs twice in meiosis, which gives it the suffix metaphase I and II.

Meiosis is a kind of cell division of a diploid cell into four haploid cells, which develop to produce gametes. In essence, meiosis is for reproductive purposes solely.

According to this question, a scientist studying a tissue sample from a sheep under a microscope finds some cells in metaphase II. This means that the tissue sample emanated from a reproductive organ.

Answer:

a. Marigold with no fertilizer

Explanation:

An experiment contains variables including independent and dependent variables. The independent variable is the variable that is changed by the experimenter, which is the TYPE OF FERTILIZER in this case, while the dependent variable is the measured variable, which is the GROWTH OF MARIGOLDS in this experiment.

However, a control group is a group that does not receive any experimental treatment. In other words, the independent variable is unchanged in the control group. The control group is regarded as the "normal" used to compare with the experimental group (group that receives treatment). In this experiment, the group of marigolds that DOES NOT RECEIVE FERTILIZER is the control group.

The property of mercury that accounts for its biomagnification in certain types of fish, resulting in high levels of mercury, is its ability to accumulate and concentrate as it moves up the food chain.

Mercury is a toxic heavy metal that can be found in various environments, including bodies of water. In aquatic ecosystems, certain types of fish can accumulate high levels of mercury through a process known as biomagnification. This occurs due to the property of mercury to accumulate and concentrate as it progresses up the food chain. Small aquatic organisms may absorb low levels of mercury from their surroundings. When larger fish consume these smaller organisms, they not only ingest the mercury present in their prey but also accumulate additional mercury over time. As larger predatory fish consume smaller fish, the mercury concentration continues to increase. This biomagnification process results in higher levels of mercury in the top predators of the aquatic food chain, such as large fish species. Therefore, the property of mercury to accumulate and concentrate as it moves up the food chain is responsible for the high mercury levels found in certain types of fish.

The morphological tree structure for the word "inflammable," which means "able to catch on fire easily," can be represented given below.

The morphological tree structure for the word "inflammable" reflects its composition and meaning. The word can be divided into two morphemes: "in-" and "-able." The prefix "in-" functions as a negation, indicating the opposite or absence of a particular characteristic. In this case, it negates the meaning of "flammable" which denotes the ability to catch fire easily. The suffix "-able" is added to the base form "flammable" to indicate the capability or possibility of the root word.

                            inflammable

                                  /      \

                            in-            -able

                             /                  \

                          not              capable

The morphological tree structure represents the hierarchical relationship between the morphemes in the word. Starting from the root node "inflammable," the tree branches out into two branches: one for the prefix "in-" and another for the suffix "-able." The prefix "in-" leads to the morpheme "not," indicating the negation of the base word "flammable." The suffix "-able" leads to the morpheme "capable," signifying the ability or possibility of the root word.

By breaking down the word "inflammable" into its constituent morphemes, the morphological tree structure helps to understand the formation and meaning of the word.

Cells of the body mainly use receptor mediated endocytosis for the selective endocytosis of most macromolecules.

Receptor mediated endocytosis is also known as clathrin-dependent endocytosis because of involvement of the membrane-associated protein clathrin in forming membrane vesicles that become internalized into the cell. Clathrin plays a major role in formation of clathrin-coated pits and coated vesicles.

Receptor-mediated endocytosis plays an important role in the selective uptake of proteins at the plasma membrane of eukaryotic cells. Endocytosis regulates many processes of cell signaling by controlling the number of functional receptors on the cell surface. Receptor mediated endocytosis is a very fast process. Invagination and vesicle formation take about 1 min. One single cultured fibroblast cell can produce 2500 coated pits per minute.

Answer:

The reactants and enzymes required for a particular biological process are concentrated in a particular organelle.

Slower

Explanation:

Enzymes are usually localized in organelles to make it easier for cellular processes to occur. Enzymes are NOT randomly distributed in the cell. Each organelle is capable of a specific function and uses specific enzymes to do these processes. Enzymes are very specific and only work for certain organelles, so they are appropriately distributed throughout cells to ensure biological processes can proceed appropriately. This is also why processes would run slower if they were just in the cytoplasm, because organelles have reactant-specific enzymes to do certain biological processes, which cannot be effectively done in the cytoplasm in the cell.
