Which of the following statements is true?O Cold blooded animals have cold blood.
Cold-blooded animals change their body temperature to match the environment.
Mammals and birds are usually cold blooded.
All of the above.

Answers

Answer 1
Answer:

Answer:

Explanation:

Cold blooded animal did not have cold blood.

Cold blooded animals can’t change their body temperature to match the environment.

Mammals and birds are not cold blooded.
Answer 2
Answer:

Final answer:

Endotherms, such as mammals and birds, are able to maintain a constant body temperature in the face of changing environmental conditions. In contrast, cold-blooded animals, or ectotherms, have a body temperature that matches their environment and varies with it.

Explanation:

An animal that maintains a constant body temperature in the face of environmental changes is called an endotherm. These animals are able to maintain a level of activity that an ectothermic animal cannot because they generate internal heat that keeps their cellular processes operating optimally even when the environment is cold.

Mammals and birds evolved endothermy, meaning they regulate their body temperature from the inside through metabolic or physical changes. This allows them to maintain a relatively stable body temperature regardless of the outside temperature.

Cold-blooded animals, also known as ectotherms, rely on external temperatures to set their body temperature. Their body temperature varies with the environment.

An experiment is designed to study the mechanism of sucrose uptake by plant cells. Cells are immersed in a sucrose solution, and the pH of the solution is monitored. Samples of the cells are taken at intervals and their sucrose concentration measured. The pH is observed to decrease until it reaches a steady, slightly acidic level, and then sucrose uptake begins. (a) Evaluate these results and propose a hypothesis to explain them. (b) Predict what would happen if an inhibitor of ATP regeneration by the cell were added to the beaker once the pH was at a steady level? Explain your thinking.

Some problems with use of DNA analysis for forensic evidence may occur because ofidentical twins.

not enough of a sample.

contaminated samples.

degraded samples.

All of the above.

Answers

Answer: Option D " all of the above "

Explanation: DNA can be a great source of information when used as a forensic evidence. This technique has many advantages and disadvantages when used as a source of information in case of crime.

Identical twins: There are some common fragments of DNA that is same in identical twins so it can be a difficulty in deciding the criminal.

Not enough of a sample: DNA should be present in a detectable amount to be used an sample for evidence, less than this detectable amount is a waste and cannot be used as a sample for evidence.

Contaminated and degraded sample: If the sample of DNA is contaminated or degraded then the result might be incorrect and might not be used as a sample for forensic evidence.

Hence, the correct answers are all of the above.

Kane how is co-evolution of symbiotic prokaryotes with eukaryotes similar and different to co-evolution in parasite-host systems?

Answers

How co-evolution of symbiotic prokaryotes with eukaryotes similar and different to co-evolution in parasite-host systems is that co existing has provided a sense of advantage with in the environment. One example of this are the parasites. There are different kinds of symbiotic relationships and this shows how similar and different co-evolution is. Hope this helps.

While mapping the motor cortex, researchers Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space

The majority of the afferent fibres that enter each region of the cerebral cortex come from a single thalamic projection nucleus. This thalamocortical projection is topographically organised so that discrete thalamic volumes project to discrete fields in the cortex, while continuous thalamic volumes project to a continuous region in the cortex. A point-to-point projection could be thought of in this respect, however this oversimplification ignores the mutual overlap of thalamic fibres inside their "modular" cortical arborization zones . Because the cerebral cortex is a two-dimensional surface and the thalamus is a three-dimensional body, the topographical depiction of the thalamic projection nuclei over the cerebral cortex is a topological problem.

Hence, Foerster and Penfield found that body areas requiring the greatest control occupied the greatest amount of cortical space.

Tail length in mammals is a heritable trait. A pig with a 6 cm tail was mated to a pig with a 30 cm tail. All F1 offspring had a tail of length 18 cm. An F2 generation was made by crossing F1 individuals. This resulted in many piglets whose tails ranged in 4-cm intervals from 6 to 30 cm (6, 10, 14, 18, 22, 26, 30). The majority of pigs had 18 cm tails, 1/64 had 6 cm tails, and 1/64 had 30 cm tails.These results are consistent with what genetic model?(a) Two genes, each with two alleles that show dominance(b) Two genes, each with two alleles that act additively(c) Three genes, each with two alleles that show dominance(d) Three genes, each with two alleles that act additivelyAn F2 piglet with an 18 cm tail is heterozygous at each of the tail-length loci, and is mated to an F2 piglet with a 6 cm tail.
