The inherited genes in these chromosomes contain DNA sequences that are related to particular what?

kicyunya [14]

Scientists first discovered chromosomes in the nineteenth century, when they were gazing at cells through light microscopes. But how did they figure out what chromosomes do? And how did they link chromosomes — and the specific genes within them — to the concept of inheritance? After a long period of observational studies through microscopes, several experiments with fruit flies provided the first evidence.
What is a gene?

Physically, a gene is a segment (or segments) of a chromosome. Functionally, a gene can play many different roles within a cell. Today, most scientists agree that genes correspond to one or more DNA sequences that carry the coding information required to produce a specific protein, and that protein in turn carries out a particular function within the cell. Scientists also know that the DNA that makes up genes is packed into structures called chromosomes, and that somatic cells contain twice as many chromosomes as gametes (i.e., sperm and egg cells).

But what were the key scientific discoveries that helped establish these principles? As it turns out, the connections between genes, chromosomes, DNA, and heredity were not recognized until long after researchers caught their initial glimpse of chromosomes. The following sections present an abbreviated summary of the major discoveries that revealed these connections.

Electromagnetic waves are all around us T or F

Law Incorporation [45]

Answer:

2. True, 3 True, 4 Trues, 5 False, 6 True, 7 True, 8 False, 9 True, 10 True

Explanation:

3. True , Electromagnetic waves have electric and magnetic energy while ocean wave have kinetic energy which is then converted into electrical energy.

4. True, the distance between all the wavelength is same until and unless it not dampened or attenuated or amplified.

5. False, Frequency measures the number of times an event takes place in a given time period.

6. True, the higher is the frequency , the more will be the energy

7. True, Gamma waves have highest frequency

8. False, our eyes could see only visible spectrum wavelengths

9. True, some object or surfaces reflect the wavelength while some absorb it.

10. True, all cosmic researches are driven by EM waves theory and related logic.

The Morphology of Homo erectus:__________.This species weighted well over 100 pounds, with an average height of about 5 feet 6 i

Katen [24]

Answer:

They had a large brain size of 700 to 1,250 cubic centimeters and large brow ridges with a nuchal torus at the back of the skull.

Explanation:

<em>Homo erectus</em> was one of the species of the homo genus which were considered the first species to have the human-like the feature that is they can stand upright on two legs and were therefore referred to as the upright man.

They showed many evolutionary advances over their ancestors called Homo Australopithecus as they showed encephalization. Encephalization refers to the increase in the size of the brain due to more neuronal complexity and neurogenesis and they possessed about 750 to 1250 cc brain size.

They showed torus at the back of the muscle which can hold the muscle of the neck and also showed the large brow ridges in the front of the skull.

Thus, the selected option is the correct answer.
