Explanation:
Phenotype, all the observable characteristics of an organism that result from the interaction of its genotype (total genetic inheritance) with the environment. Examples of observable characteristics include behaviour, biochemical properties, colour, shape, and size.

Explanation:
Golden algae
Diatoms
None of the above
Answer:
The correct answer will be diatoms.
Explanation:
Diatoms are photosynthesizing micro-algae found in both marine and freshwater usually hard and rough in appearance due to deposition of silica in their cell walls.
They live in both photic and planktic region of the ocean and in both unicellular to colonial forms and form the major part of the planktons.
Their large number of species counts for about 20,000 and new species being discovered every year and their reproduction through simple cell division makes the most numerous unicellular algae in the oceans
Thus, diatoms is the correct answer.
The type of mutation that causes sickle cell anemia is called a point mutation.
A point mutation in both copies of the HBB gene results in the hereditary illness sickle cell disease (SCD).
An element of hemoglobin, the protein in red blood cells that carries oxygen, is encoded by this gene. Because of the mutation, hemoglobin molecules clump together to form red blood cells with a sickle shape.
About 100,000 people in the US have the rare disease sickle cell anemia. It primarily affects persons who have ancestors in regions of the world where malaria is common and who also have a gene that offers some protection against anemia. Additionally, this gene causes sickle cell anemia.

Here is the proof
The delay between the atrial and ventricular contractions is caused by the atrioventricular node (AV node). The AV node is a small cluster of cells located between the atria and ventricles.
It acts as a gatekeeper, slowing down the electrical signal from the atria so that the ventricles have time to fill with blood before they contract.
There are two main reasons for the delay at the AV node:
The AV node cells have a high threshold for depolarization. This means that they need to be depolarized to a higher level than the cells in the atria before they will fire an action potential.
The AV node cells have a long refractory period. This means that they cannot be re-excited for a period of time after they have fired an action potential.
The combination of these two factors creates a delay of about 0.12 seconds between the atrial and ventricular contractions. This delay is essential for proper heart function, as it allows the ventricles to fill with blood before they contract.

Answer:
ventricular dyssynchrony
Explanation:
CHOICES:
A) The air particles inside the balloon slow down due to lower thermal energy. As a result, fewer collisions take place per second and this leads to a lower pressure inside the balloon. The pressure on the outside of the balloon pushes the balloon to a smaller volume.
B) The air particles inside the balloon slow down due to lower thermal energy. As a result, the air particles become charged, attract to each other and take up a smaller volume. Therefore, the balloon shrinks.
Eliminate
C) The rubber latex of the balloon becomes colder and will resist stretching and push the air particles inward until the inside pressure equals the outside pressure and equilibrium is established.
D) The density of the air particles increases within the balloon causing some particles to escape out of the balloon. This leads to an increase in the particles and, thus, pressure outside the balloon. This causes the balloon to collapse.
A. A phase of rapid growth occurs.
B. Only occurs during cell division.
C. Cell division is not occurring.
D. The cell prepares for division by duplicating its chromosomes within the nucleus (replication).
All of these things occur during interphase except:
B. Only occurs during cell division
Interphase is where the cell grows and duplicates its DNA, and this process comes before cell division. Interphase does not occur during cell division, but prepares for it.
