Explanation:
A missense mutation is when the change of a single base pair causes the substitution of a different amino acid in the resulting protein. This amino acid substitution may have no effect, or it may render the protein nonfunctional.
What type of biological molecule is an exonuclease.
Answer:
Enzyme (protein)
Explanation:
Exonucleases are enzymes that catalyze the removal of nucleotides in either the 5-prime to 3-prime or the 3-prime to 5-prime direction from the ends of single-stranded and/or double-stranded DNA. Removal of nucleotides is achieved by cleavage of phosphodiester bonds via hydrolysis.

Identify the stages of the cell cycle using the drop-down menus. Label A-E
Picture attached
Answer:
A - G1 phase
B - G2 phase
C - S phase
D - Mitosis
E - Interphase
Explanation:
Interphase is all the parts of the cell cycle excluding mitosis, and encompasses G1, S, and G2 phases. Cells spend most of their lives in interphase
G1 is the first gap phase, where the cell is growing and making checks in preparation for mitosis. During S phase (the synthesis phase), the DNA is replicated. This is so a full copy of the DNA can be passed on to the daughter cells.
During the G2 phase, the final checks are made before the cell undergoes mitosis, which is where the cell divides.
Answer:
A. G1 phase
B. S phase
C. G2 phase
D. Mitosis
E. Interphase

Which of these is an example of an independent
variable and its effect on a dependent variable?
A. age and race
B. burgers and hotdogs
C. the Sun and the temperature outside
D. cooking at home and ordering takeout
The independent variable is the one that causes a response in the dependent variable. Option C. the Sun and the temperature outside
What is an independent variable?Refers to all the variables in an experiment that provoke a response in another variable.
An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable.
What is a dependent variable?Refers to the variable, which response depends on any change in the independent variable.
It represents a quantity of something whose value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable.
In the exposed example, the correct option is C. the Sun and the temperature outside.
The Sun ⇒ Independent variable ⇒ According to how its proximity fluctuates it provoke a temperature change.Temperature ⇒ Dependent variable ⇒ It depends on the Sun

How could the origin of organisms such as dinosaurs, whose gait allowed them to move without compressing their lungs, have led to emergent properties?.
The ability of dinosaurs to move without compressing their lungs helped them to effectively produce more energy requited for other emergent properties.
What was the advantage of being able to breathe with lungs?The lung is a special organ in the body of higher animals such as mammals and birds whose function is for gaseous exchange.
Possession of the lung gave an evolutionary advantage to organisms that have lungs as it enabled them to occupy various habitats on land as they could effectively use oxygen to produce energy.
Therefore, the ability of organisms such as dinosaurs to move without compressing their lungs helped them to effectively produce energy for other emergent properties.

What types of cells perform photosynthesis
Answer:
Photosynthetic cells are quite diverse and include cells found in green plants, phytoplankton, and cyanobacteria. During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
Explanation:
i hope this helps :)
Green plants, phytoplankton, and cyanobacteria all have cells that can synthesize oxygen.
Thus, Photosynthetic cells are highly diverse. Cells create sugar molecules and oxygen during the process of photosynthesis by using carbon dioxide and energy from the sun.
Chloroplasts, specialized cells present in plant cells, are principally responsible for photosynthesis.
The cells of the leaves of plants, notably the specialized structures known as mesophyll cells, are where photosynthesis mostly takes place within plant cells. Numerous chloroplasts, where photosynthesis occurs, are present in the mesophyll cells.
Thus, Green plants, phytoplankton, and cyanobacteria all have cells that can synthesize oxygen.
