Which of these is NOT characteristic of chordates?

Biology
1 answer:
Leya [2.2K]3 years ago

The option which is not a characteristic of chordates is chloroplasts in their cells.
Chordates do have a dorsal supporting rod (vertebrates are types of chordates - they have a spine), a dorsal hollow nerve cord (within the spine), and pharyngeal pouches. However, they do not have chloroplasts, because that is a characteristic of photoautothropic eukaryotes, which chordates certainly are not.

Airida [17]

What can be inferred from this excerpt is : ( D )  Individuals with favorable variations survive and reproduce.

<h3>Effects of genetic variations in species</h3>

When the insecticide was sprayed some of the cockroaches survived and continued reproduction due to their resistance to the spray.Therefore it can inferred that although the cockroaches share the same genetic materials, the variations in individuals within the same specie played a role in the survival of some of the cockroaches.

Hence we can conclude Individuals with favorable variations survive and reproduce.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

                                Observed(o)   Expected(e)   (o-e)    $(o-e)^2$      $(o-e)^2/e$

Green-melon plant        53                    47               6          36             0.766

Yellow-melon plant        41                    47              -6          36             0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Touch sensations and proprioception are carried primarily along the:
Radda [10]

Answer:

b. dorsal column system  

Explanation:

The backbone system is responsible for the sensation of touch and proprioception (which is the ability to recognize the spatial location of the body, its position and orientation, the force exerted by the muscles and the position of each body part relative to the others).

This system transmits information outside the body to a region called the postcentral gyrus in the cerebral cortex, which transmits stimuli, sensed by the body, to the brain.
