Answer:
An ionic bond is formed between a metal and a non-metal. Covalent bonding is a form of chemical bonding between two non metallic atoms which is characterized by the sharing of pairs of electrons between atoms and other covalent bonds.
Explanation:
There are two types of atomic bonds - ionic bonds and covalent bonds. They differ in their structure and properties. Covalent bonds consist of pairs of electrons shared by two atoms, and bind the atoms in a fixed orientation. Relatively high energies are required to break them (50 - 200 kcal/mol). Whether two atoms can form a covalent bond depends upon their electronegativity i.e. the power of an atom in a molecule to attract electrons to itself. If two atoms differ considerably in their electronegativity - as sodium and chloride do - then one of the atoms will lose its electron to the other atom. This results in a positively charged ion (cation) and negatively charged ion (anion). The bond between these two ions is called an ionic bond.

phenotype and genotype of this punnet square?
Answer:
Phenotype: whatever the capital P is
PP and Pp
Explanation:
So the genotype is PP 1/2 Pp 1/2
and so in your question it should have whatever the "PP" and "Pp" stand for in your question would be it. So lets say red flower = PP and Yellow flower = Pp so it would be Red Flower 1/2 and Yellow Flower 1/2
Hope it helped!

plant cell
label the boxes with words from the word bank
Answer:
Explanation:
cell wall – provides rigid structure and protection; made of cellulose (dark green)
cell membrane – surrounds the internal cell parts; controls passage of materials in and out of the cell cytoplasm – everything inside of the cell membrane except for the nucleus (light green)
nucleus – control center of the cell; contains DNA (light pink)
nucleolus – composed of protein and RNA; involved in ribosome production (dark pink)
cytoskeleton – provides strength and shape to the cell; network of protein fibers (orange)
endoplasmic reticulum (ER) – passageways that transport proteins within the cell (purple) mitochondria – produces energy (rust or red)
chloroplast – uses the energy of sunlight to produce glucose during photosynthesis (medium green) vacuole – vesicle that provides storage of water and other materials; full vacuoles provide support (blue) lysosome – vesicle that contains substances that break down materials (navy)
Golgi body – packages and transports proteins from the ER to other parts of the cell (gold)
ribosomes (the dots) – where proteins are made in the cell

What do cells need to complete aerobic cellular respiration
Answer:
Cellular respiration is the aerobic process by which living cells break down glucose molecules, release energy, and form molecules of ATP. Overall, this three-stage process involves glucose and oxygen reacting to form carbon dioxide and water.
Explanation:
Cells require Oxygen and glucose to complete aerobic cellular respiration
During Aerobic Cellular respiration, glucose and water reacts with each other to release energy in the form of ATP that is used/stored up in the cells of the organisms. below is the cellular respiration reaction
cellular respiration :
[tex]C_{6} H_{12} O_{6} + 6O_{2} ---->6CO_{2} (gas) + 6H_{2} O + energy[/tex]
Hence we can conclude that Cells need Oxygen and glucose to complete aerobic cellular respiration

What organelle(s) gives plant cells their shape?
O A chloroplasts
O Blarge central water vacual
O C cell wall
O D both B and C contribute to the plant cells shape.
Answer:
A. Chloroplasts
Explanation:
Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, which are not found within animal cells. The cell wall is a rigid covering that protects the cell, provides structural support, and gives shape to the cell.

theory?
A) Plants and animals are made up of structural
units known as cells.
B) Mitochondria and chloroplasts contain genetic
material and can replicate.
C) All cells arise from preexisting cells.
D) The cell is the basic functional unit of all living
things.
The statement describes an exception to the cell theory - B) Mitochondria and chloroplasts contain genetic material and can replicate.
The cell theory is the theory that is given by German researchers Theodor Schwann, Matthias Schleiden, and Rudolph Virchow. This theory states three major principles:
All living organisms are composed of one or more cells.The cell is the basic unit of structure and organization in organisms.Cells arise from pre-existing cells which means cells divide and pass on hereditary informationenergy flows within cells.Thus, the statement describes an exception to the cell theory - B) Mitochondria and chloroplasts contain genetic material and can replicate.

What unique features do you notice about the shape of these cells? How might this improve their ability to absorb materials?
Cells are the functional and structural units of life. The cells make up the tissues, organs, and organ systems. The cells based on the shapes and properties differ in their functions.
In the given image, the special features of the cells of the digestive tract are microvilli.
Villi are the finger-like projections present on the intestinal wall. These will function in increasing the surface area to enhance the digestion process.
On the surface of the villi, numerous micro-hair-like projections are presently known as microvilli. The microvilli are the help in increasing the surface area of the villi.
These finger-like projections create a wave or brushing-like movement for the increased absorption and surface area.
Therefore, the given image is of microvilli that helps in increasing the surface area.
