Which gland of the endocrine and nervous system controls the other glands in the body?

As the human population increases l, which problems is technology least likely to be able to solve

LuckyWell [14K]

The correct answer would be: dependence on nonrenewable resources.

A nonrenewable resources are resources that cannot be readily replaced by natural means, such as fossil fuels (oil, natural gas). The use of these resources is not sustainable because their formation takes billions of years. The whole world is dependent on these non-renewable sources but they are becoming more scarce daily.

Electrophysiological studies of rats learning T-mazes have found a. different patterns of activation in the basal ganglia during early learning and later stable performance

Explanation:

Forced alternation and left-right discrimination tasks using the T-maze have been widely used to assess working and reference memory, respectively, in rodents.
Basal ganglia are strongly interconnected with the cerebral cortex, thalamus, and brainstem, as well as several other brain areas. The basal ganglia are associated with a variety of functions, including control of voluntary motor movements, procedural learning, habit learning, eye movements, cognition, and emotion.
The direct pathway, sometimes known as the direct pathway of movement, is a neural pathway within the central nervous system (CNS) through the basal ganglia which facilitates the initiation and execution of voluntary movement.
Damage to the basal ganglia cells may cause problems controlling speech, movement, and posture. This combination of symptoms is called parkinsonism. A person with basal ganglia dysfunction may have difficulty starting, stopping, or sustaining movement.

Some people argue that evolution, which is generally associated with progressive increases in the

yKpoI14uk [10]

This argument would not be valid because it fails to take into account the mechanisms through which evolution occurs and misunderstands the second law of thermodynamics.

The second law of thermodynamics states that the total entropy of a system must always increase. The argument stating that this law disproves evolution given that evolution can be considered as a decrease in entropy, fails to realize that the second law states that the total entropy must increase, this does not mean that entropy cannot decrease at one point, to then increase more so at another.

The other aspect of evolution that this argument fails to account for is that evolution is a chaotic process. Evolution, though having a final product that may be considered as increasing in organization, is at heart a chaotic process caused by random mutations and the fragile process of natural selection. Therefore, rather than disprove it, the second law of thermodynamics is actually the driving force behind continued evolution.

Which microscope were cells first observed?

lutik1710 [3]

Answer:

Leeuwenhoek made his own microscope lenses, and he was so good at it that his microscope was more powerful than other microscopes of his day. In fact, Leeuwenhoek's microscope was almost as strong as modern light microscopes.

Predict what the calf produced in a union between each of these parents might look like. Explain your answers.

Charra [1.4K]

We know that purebred means that the organism contains the same alleles for the trait and hybrid means that it contains two different alleles for the trait. Dominant means that it will be shown in a hybrid and a purebred, but recessive traits will only be shown in purebred recessive organisms.

a) The offspring of a purebred white (recessive) cow and a purebred brown (dominant) bull, would be all hybrid brown (dominant). This is because as I stated above, dominant traits are shown when the offspring has both dominant and recessive alleles for the same trait.

b) The offspring of a purebred brown (dominant) cow and a purebred brown (dominant) bull would all be purebred brown (dominant). This is because if both of the parents have only alleles that code for brown color, the only color that the offspring can be is brown.

c) The offspring of a purebred white (recessive) cow and a purebred white (recessive ) bull would all be purebred white (recessive), for the same reason stated above in part b), the only difference being that the alleles are recessive and code for white color instead of being dominant and coding for brown color.

d) The offspring of a hybrid brown (dominant) cow and a purebred white (recessive) bull would be half hybrid brown (dominant) and half purebred white (recessive). This can be seen best if you set up a Punnett Square, which is a diagram that shows allele frequencies in offspring. This shows you that the chance that the offspring get the dominant allele from the mother cow is 50%, thus 50% would be hybrid brown (dominant), as the father can contribute only a recessive white allele. The other 50% would be purebred white (recessive) because the mother cow would be contributing a white allele and so would the father.

Hope this helps! :)
