Answer:
All euglena have chloroplasts and can make their own food by photosynthesis. ... Euglena move by a flagellum (plural ‚ flagella), which is a long whip-like structure that acts like a little motor. The flagellum is located on the anterior (front) end, and twirls in such a way as to pull the cell through the water.
Explanation:
In general, flagellum is a long whip like organ which protrudes to the exterior from the cell body and permits mechanical work without any marked change in the form of the effector cell. In Euglena, there are two flagella. One of them is equal in length to body while other is short.
Answer:
True
Explanation:
Let the allele for green color of pods be G
and the allele for yellow color of pods be g
Phenotype of true breeding parent with green colored seeds is GG
Phenotype of true breeding parent with yellow colored seeds is gg
In F1 cross
GG mates with gg
Genotype of offspring - Gg
Phenotype of offspring - Green seed
Since the offspring has both the allele for green and yellow seeds color but yet only green is expressed. This indicate that green allele dominated the expression of yellow allele thus, it can be concluded that green seed pods were dominant over yellow seed pods.
Complete question:
Phenotype Genotype Number of Individuals
Long-tailed TT 260
Long-tailed Tt 160
Short-tailed tt 80
If 20% of the long-tailed cats got their tails stuck in something and failed to reproduce, what would be the expected change in frequency of T in the next generation
Answer:
The expected change in allelic T frequencies probably changes from 0.6 to 0.57 in the following generation.

Due to technical problems, you will find the complete question, answer and explanation in the attached files.
Investigators should keep in mind that eyewitness identification is highly infallible. true, since the law takes the identification as a positive test and completely commits those involved and an error in it could tarnish the course of justice and consequently of the investigators.
Answer:
Explanation:
This question is incomplete because of the absence of the graph. However, the independent variable of an experiment is the variable that is not affected by any other variable during the course of the experiment but is however intentionally or unintentionally predetermined by the researcher conducting the experiment. For example, in an experiment to determine the effect of age on blood pressure; age is the independent variable because the age class/groups of the individuals to be used can be determined by the researcher also the age cannot be affected by the pressure (the age of a person cannot change because of an increase/decrease in blood pressure).
Also, the control of an experiment is the variable/data in which other data in the same experiment are compared to. For example, in an experiment to determine the effect of a substance (such as sepin-1) on the growth of cancer cells (using a culture medium), the control can be the culture medium that was not given any substance or the culture medium that was given a pure substance of no effect like water. This means, in this control culture medium, the cancer cells will continue to grow normally while that growth will be compared with what is seen in the culture medium treated with sepin-1.
