Answer:
A single gene on the Y chromosome plays a crucial role in the parental development of the testes.
Explanation:
Y chromosome is present only in males and this chromosomes is the distinguishing factor which separates males from females. It is the smallest chromosome but of utmost importance due to its sex determining feature. Up till now, studies show that Y chromosomes only carry limited amount of genes.
The Y chromosome, most importantly, comprises of the SRY gene. This is the gene responsible for determining the testis and for the development of the testis. The SRY gene is responsible for sex determination.
Answer:
Scientists need instruments to measure the world. Instruments and sensors are needed to collect data - that takes engineering to design and build them.
Explanation:
Olds and Milner showed that electrical stimulation of particular brain regions could have a reinforcing effect.
<h3>Electrical brain stimulation</h3>
it is commonly known as focal brain stimulation (FBS), is a type of electrotherapy used in clinical neurobiology and research to activate a neuron or neural network in the brain by either directly or indirectly stimulating its cell membrane with an electric current.
<h3>What is the purpose of brain electrical stimulation?</h3>
- Electrical stimulation can be used to alter how the brain functions because electrical charges are what cause brain activity.
- Brain stimulation has been used to treat stress and mood disorders, and it can even make it easier for people to remember things, solve puzzles, and pay attention.
