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.

the solutes in the solution have a lower concentration than the solute concentration inside the plant cell.
the water is moving down its concentration gradient from high to low. the water is moving down its concentration gradient from low to high.
Answer:
The correct answer is -
the water in the solution moves into the plant cell
the solutes in the solution have a lower concentration than the solute concentration inside the plant cell
the water is moving down its concentration gradient from high to low.
Explanation:
The hypotonic solution consists low concentration of solutes and a higher concentration of water as compared to the concentration of solutes and water of other solutions or cells. Water tends to move from a higher concentration of water to a lower concentration of water therefore the cell swell and then ultimately burst.
Water movement in such conditions is known as the movement down the concentration gradient as it moves from its higher concentration to a region of its lower concentration.
Compare and contrast the shape of
a solid, liquid and mass.
Answer: See below
Explanation:
A solid will retain its shape, Liquid matter is made of more loosely packed particles and will take the shape of its container. Mass, or form, refers to a shape or three-dimensional volume that has or gives the illusion of having weight, density or bulk. They compare because mass and solid have their respective shape yet liquid matter takes shape of its container

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

how does our water use affect the bay-delta ecosystem?
Answer:The Sacramento-San Joaquin Rivers Delta and San Francisco Bay (hereinafter “Bay-Delta”) is an important economic and environmental resource benefitting all of California and the nation. The Northern California Water Association (NCWA) and Sacramento Valley water resources managers recognize the importance to California’s future of a healthy Bay-Delta and providing high quality and reliable water supplies for all beneficial uses. For the past several decades, NCWA has been a strong and constructive participant in the various processes designed to help solve the challenges in the Bay-Delta. We will continue to play a constructive role in implementing necessary solutions to Bay-Delta problems, as long as the actions do not affect the ability to serve water for multiple beneficial uses in the Sacramento Valley, including cities and rural communities, fish, farms, birds and recreation.
NCWA and Sacramento Valley water resources managers have supported the state’s co-equal goals–providing a more reliable water supply for California and protecting, restoring and enhancing the Delta ecosystem–and have encouraged success in Voluntary Agreements as a new way forward in California.

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
