Answer: Alexandrium catenella is a species of dinoflagellates. Alexandrium has two flagella that enable it to swim. While one flagellum encircles the cell causing the cell to rotate and move forward, the other extends behind the cell and controls the direction.
The cell wall is composed of cellulose Theca.
Length 20 - 48 μm, width 18 - 34 μm
Yellow-green to orange-brown
Forms chains of 2, 4 or 8 cells
The color that the new generation's offspring show will be red, pink, and white.
The young creation of living things is called an offspring, which can be created by a single organism or, in the event of sexual reproduction, by two organisms. A group of offspring is sometimes referred to as a brood or progeny in a more generic sense.
All of the pink-flowered progeny are produced when a red-flowered plant and a white-flowered plant are crossed. This cross serves as an example of the incomplete dominance of red and white. The mixing of both alleles results in this circumstance. Gene interaction known as incomplete dominance occurs when only one of two alleles of a gene at a locus is fully expressed, frequently leading to an intermediate or distinct phenotype. Additionally called partial dominance.
CRCW × CRCW = CRCR, CRCW, CWCW i.e, red, pink, and white.
The complete question is:
A red carnation is crossed with a white carnation: Neither one is 3 Fonts dominate over the other: This means that when crossed, their offspring can show pink flower The parent generation genotypes are: CR CR and CW CW (RED x WHITE) An offspring showing pink flowers (CR CW) from the parent generation is now being bred with another pink flower (CR CW) What color will this new generation's offspring show?

Answer:
According to the current fossil record, scientists believe that the life on earth began about 3.5 billion years ago.
Answer: Option B
Explanation:
In a typical energy pyramid the amount of energy that is being transferred is only 10% rest of the energy is lost in the form of heat.
The energy from the sun is converted in the form of chemical energy which is stored in the producers.
10 per cent of this energy is transferred to the next trophic level and rest of the energy is lost in the form of heat. This goes on, there is only a transfer of 10 % energy from the successive levels.
So, if the producers have 200 Kcal/m2/year energy the the primary consumers will have 10% of this energy which is equivalent to 20 Kcal/m2/year and then the secondary consumers will have 10 % of 20 Kcal/m2/year which is equivalent to 2 Kcal/m2/year.
