Answer:
All cells contain a nucleus and a nuclear envelope and the liver cell is no exception. It has exactly the same control over the cell as the palisade nucleus does. To keep it all together, it is surrounded by a cell membrane.
Explanation:
Since a liver cell is an animal cell, it lacks chloroplast. Below the epidermis of the leaves is a palisade cell. It participates actively in photosynthesis, chloroplasts are present.
What structures are found in liver cells?Liver cells lack a cell wall but do have a nucleus and a cell membrane. It receives blood from two main sources: The Hepatic Portal Vein, which delivers blood from the digestive tract that is nutrient-rich.
The nucleus and nuclear envelope are components of every cell, including liver cells. The cell is under the exact same management that the palisade nucleus is. It is encased in a cell membrane, which serves to keep everything together.
Therefore, as an animal cell, the liver lacks the cell wall, chloroplast, and big vacuole that are often seen in plant cells.

what is the first structure to emerge from a germinating seed
Answer:
The radicle is the first structure to emerge
The root apical meristem produces a root cap to protect the radicle, which emerges first from the seed to improve water uptake.
What is germination?Germination is the process through which a seed, spore, or other reproductive body typically breaks dormancy and begins the process of sprouting.
The embryo absorbs water and expands cells during seed germination. After water intake, or imbibition, respiration increases and metabolic functions, paused or greatly decreased during dormancy, resume. These processes are linked to structural changes in embryo cell organelles (metabolic membranes).
The radicle, which is the primary embryonic root, emerges from the seed first in order to maximize the plant's capacity to absorb water. The root cap, which is produced by the root apical meristem, serves to shield the radicle.

Tyrone and Valerie wanted to determine what feature of a paper airplane would cause it to fly the farthest. Tyrone made his airplane with wider wings than Valerie's airplane. Valerie's airplane had shorter wings than Tyrone's. After testing the two airplanes several times, the data shows that wider wings help airplanes fly farther than shorter wings.
Which characteristic of science is missing from this experiment?
The question is not testable because paper airplanes are always changing.
The phenomenon is not observable because air resistance changes.
The experiment is not replicable because controlled variables are not included.
The results are not reliable because the airplanes were only tested one time.

ОА.
True
OB.
False
Answer:
True
Explanation:
Answer:
True
Explanation:
Wandering. When overpopulated animals are starving, their innate survival instincts cause them to wander into unnatural places in search of food. In many cases, overpopulated animals will wander into areas populated by humans. The outcome is animals killed on the highway, property damage and human injury.

Cellular respiration occurs in a sequential order, this allows the cell to extract the energy it needs from glucose.
Cells need a constant supply of energy to preserve the biological order that keeps them alive, this energy comes from chemical bonds in food molecules, which are fuel for cells.
Cellular respiration is one of the most important processes that occur within living cells, it is constituted by a series of oxide reduction reactions, which allow obtaining energy through the degradation of an organic substance, glucose.
The cells that make up the body take advantage of the energy of chemical bonds, contained in glucose, when the molecule is degraded and oxidized to carbon dioxide (CO2) and H2O.
This energy is stored in the form of high-energy bonds (covalent bonds that release large amounts of energy when hydrolyzed) in ATP and NADPH molecules.
In turn, these carrier molecules are like portable sources of the chemical groups and electrons necessary for biosynthesis.
Therefore, we can conclude that cellular respiration occurs in a sequential order, this allows the cell to extract the energy it needs from glucose.
