If the outside temperature decreases by 20 degrees Celsius, what will happen to a reptile’s body temperature?
oksian1 [2.3K]

The reptile's body temperature rises when the external temperature rises. When the temperature drops, so does his body temperature. If a reptile feels cold because the external temperatures have made his blood cold, he'll lie in the sun to warm up. However, if the external temperature is too high, he scurries under a rock, dives in a pool or finds some kind of shade where he can cool down. Reptiles and other animals with ectothermic systems are vulnerable to extreme changes in temperature because they can't control their temperatures internally. They can control their body temperatures only by moving to an environment with a suitable ambient temperature.

How do you do this biology work
wolverine [178]

Answer:

22 pairs of autosomes, 1 pair of sex chromosomes, I notice that the X and Y chromosomes are sex chromosomes and that they are different in length and size., The sex of this organism is male, as the genotype XY can only mean a male gender; female gender is denoted by the genotype XX., You didn't put in Karyotype A., The special circumstance is with group 21 of chromosomes. There are 3 instead of 2 in that group., This circumstance results in a condition known as trisomy 21, or Down Syndrome. Down syndrome causes a distinct facial appearance, intellectual disability, developmental delays, and may be associated with thyroid or heart disease. , Name the karyotype "Down Syndrome Karyotype?" (I'm not sure on the last one)

Vesicles that come from the trans-golgi can fuse with which organelles?
astra-53 [7]

Answer:

Transport vesicles, containing partially processed proteins, fuse with the folds of the <u>Golgi apparatus (cisternae)</u> on the cis face and bud from the cisternae on the more distal side (trans face).

Explanation:

Some of the matrix proteins form long, filamentous tethers that are thought to help retain Golgi transport vesicles close to the organelle. When the cell prepares to divide, mitotic protein kinases phosphorylate the Golgi matrix proteins, causing the Golgi apparatus to fragment and disperse throughout the cytosol.
