How is linkage used to make gene maps?

Answers

Answer 1

Answer: Step one: cross two animals that have dissimilar and simply documented phenotypes. Evidence the phenotypes in all the progeny.

Step two: do a DNA test that ways which sets of DNA indicators move jointly in the several descendants.

Step three: associate the DNA map with the phenotypes, and you'll be capable to shape a map that displays which phenotypes communicate to which chromosomal positions.

Sunlight provides _____ for plants.a. gravity
b. energy
c. temperature
d. photosynthesis

Answers

Sunlight provides photosynthesis for plants. Photosynthesis is the process done by plants and other organisms, to convert the light from the sun into chemical energy that would be useful (it involved energy transformation.) In plants, the sunlight is being converted into glucose from carbon dioxide and water.

Answer:

B) Energy

Explanation:

Energy let the plant do Photosynthesis

What is the difference between sensory and motor neurons?

Answers

Sensory neurons carry signals from the outer parts of your body into the central nervous system. Motor neurons carry signals from the central nervous system to the outer parts of your body including muscles, skin and glands.

Sensory neurons.. Well sense any feeling, taste, sound around you. They send messages to your brain. Motor neurons are the nerves that react to the messages

How does mass extinction affect species that survive?There are no surviving species if a mass extinction occurs.

They will soon become extinct.

They combine gene pools.

They fill new roles in the changed environment.

Answers

When there is a mass extinction, species that survive will combine gene pools. A gene pool is the sum of population of same species have the same genetic material. Those species that survived will combine for them to survive from extinction. If there is a combination of gene pool then there will be a possibility that evolution will happen

The mass extinction may cause the arrival of new species in the new and changing environment.

Further Explanation:

Mass extinction is the phenomenon when there is the extinction of many organisms or the group of an organism from the Earth due to change in environmental condition as it would not allow the survival of these organisms in the new environmental condition. This may cause the appearance of a new organism or the spread of mutant organisms in the prevailing environment that may play new roles. Hence new kind of ecosystem may be formed in the changing environment and those organisms that survive or get adapted to this condition may reproduce more and increase in number.

Therefore mass extinction although causes removal of some organism but may provide a new platform for the arrival of new kind of species and formation of a new ecosystem.

Which of the following is not true concerning tropical plantations?a. They are generally found in humid, tropical climates.
b. Wheat and corn are common products of tropical plantations.
c. Most crops from tropical plantations are exported.
d. Cocoa, coffee and tea are common products of tropical plantations.

Answers

The right option is; b.

Wheat and corn are common products of tropical plantations is not true concerning tropical plantations.

Tropical plantations is a type of agriculture in which perennial plants are grown for several years. Tropical plantations are usually practiced in regions with humid, tropical climates and plants such as cocoa, coffee, tea, coconut, rubber and oil palm are the common crops that are cultivated. The crops are mostly exported and they serve as important source of income. Wheat and corn are not common products of tropical plantations .
