Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.
However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.
Hence, Hydrogen is an element which does not want to have eight valence electrons.

Different types of cells can have certain organelles and structures in common. Which types of cells definitely contain cell walls?
SC.912 L 14.3
O plant and animal cells
0 plant and eukaryotic cells
o plant and prokaryotic cells
animal and eukaryotic cells
Answer:
plant and eukaryotic cells (B)
Explanation:
animal cells have a cell membrane but no cell wall and prokaryotic organisms lack a nucleus or any other membrane bound cell organelle.
Plant and prokaryotic cells definitely have a cell wall. So, the correct option is C.
What is Cell wall?Cell wall is defined as the structural layer that consists of polysaccharides and is present outside the plasma membrane which can be rigid, rigid and flexible. This provides protection to the cell from external factors that may be harmful to the cell and also provides structural support.
Plant and prokaryotic cells definitely have a cell wall. The cell wall of a prokaryotic cell is present under the capsule while the cell wall of a plant cell is a specialized form of extracellular matrix that surrounds each cell of a plant. This provides structural support to the cell and protects the cell against infection and mechanical stress
Therefore, the correct option is C.

Explanation:
oxygen aids in glucose production through respiration and supports the organism since glucose is the food for plants
The role of oxygen in photosynthesis and in cellular respiration - B Oxygen is released in photosynthesis and used in cellular respiration to produce energy.
Role of oxygen1. In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct.
6CO₂ + 6H₂O+ energy → C₆H₁₂O₆ + 6O₂
2. In respiration, the product of photosynthesis, glucose and oxygen are converted into carbon dioxide, water, and energy and oxygen is used to break down glucose
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O+ energy

In what way is surface area more important for cells than volume?
Answer:
As a cell grows in size, the surface area gets bigger, but the volume gets bigger faster. Thinking about this as a ratio (division), the volume is the denominator and the surface area is the numerator. If the volume is getting very big, then the ratio itself will be getting very small.

When the codon and anticodon connect.... What does it build ?
Answer: A tRNA with the complementary anticodon is attracted to the ribosome and binds to this codon. The tRNA carries the next amino acid in the polypeptide chain. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.
5. The model includes a wavy arrow to show light striking the thylakoids. Which
label for the wavy arrow would be MOST USEFUL for communicating the role of
light in photosynthesis?
a. Light is radiated from the chloroplast during the light-independent reactions.
b. Light energy is cycled within the thylakoid.
c. The chloroplast reflects the green wavelengths of light.
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Answer:
There is no model in this question but the question can be answered based on the provided information and general knowledge of photosynthesis. The answer is:
d. Light is the energy source for converting ADP to ATP, and NADP+ to NADPH.
Explanation:
Photosynthesis, which is being described in this question, is the process by which autotrophic organisms synthesize their food in the presence of sunlight. The photosynthetic process occurs in the CHLOROPLAST. However, photosynthesis occurs in two stages namely: light dependent and light independent reaction.
Light dependent reaction occurs specifically in the THYLAKOID of the chloroplast where the photons of light is absorbed by chlorophyll molecule (photosynthetic pigment). The light energy that hits the chlorophyll makes it excited, hence, providing the energy to produce ATP from ADP and NADPH from NADP+.
These products are pivotal in the next stage of photosynthesis (light independent stage). Hence, light plays a very crucial role in photosynthesis by providing the energy source for converting ADP to ATP, and NADP+ to NADPH.

If purple flowers are dominant in a plant and white flowers are recessive in that plant, then when purple-flowered
plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first
generation of offspring should have
A
100% white flowers
B
75% purple flowers and 25% white flowers
с
50% purple flowers and 50% white flowers
D
100% purple flowers
im pretty sure it would be c
If purple-flowered plants with two dominant genes are mated with white-flowered plants with two recessive genes, the first generation of offspring should have 100% purple flowers.
Genes are defined as units of inheritance that occur in the chromosomes. Usually, genes occur in pairs called alleles and these alleles control the expressed traits (phenotype) of an organism.
In this case, we have a flowering plant having a dominant gene for purple flowers (R) and a recessive gene for white flowers (r). Using a punnet square, we can see that the first generation will have all purple flowers since it is the dominant gene as shown.
