Every monarch butterfly migrates. This statement _______. A) is true B) can be made true by change "Every" to "No" C) can be made true by deleting "monarch" D) can be made true by changing "Every" to "The final generation

Answers

Answer:

The answer is option A "Is True"

Explanation:

The Monarch is notable for its capacity to travel significant stretches, and the migrations in North America are one of the best common marvels on the planet. This butterfly is additionally periodically recorded from the English Isles, making it our biggest and most extraordinary traveler butterfly.

Each fall, a great many ruler butterflies move 3,000 miles from their favorable places in northeastern North America to spend the colder time of year in the timber lands of southwestern Mexico. Every movement is by new generation, so they can't gain from others. All things being equal, they depend on their qualities. Their antennae have a genetic clock that reveals to them when to move and to explore they measure the sun's situation not too far off with their eyes.

A mutation that could be inherited by offspring would result from-?

Answers

Answer: Along with substitutions, mutations can also be caused by insertions, deletions, or duplications of DNA sequences. Some mutations are hereditary because they are passed down to an offspring from a parent carrying a mutation through the germ line, meaning through an egg or sperm cell carrying the mutation.

Explanation:

A mutation that could be inherited by offspring would leads from a base substitution in gametes during meiosis. The correct option is D.

What is mutation?

Any alteration to a cell's DNA sequence. Alterations in cell division can result in specific mutations.

As can exposure to environmental DNA-damaging substances. Mutations may be negative, positive, or ineffective.

Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.

Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.

A base substitution in gametes during meiosis would result in a mutation that might be passed on to progeny.

Thus, the correct option is D.

b. lack of pollinating insects
c. higher initial costs
d. increased erosion
e. increase labor costs

Answers

Answer:

I think its A and E

Explanation:

^^^^^^

The challenges to implementing sustainable farming practices: higher initial costs;  increase labor costs.

What is  sustainable agriculture?

It is an integrated system which includes both plant and animal farming practices, which hence has a minimum effect on the environment. It involves using substances of natural origin and hence meets the needs without causing an adverse impact on the environment.

What are its advantages?It prevents pollution since the waste remains in the farm's ecosystem.There is a reduction in the production of waste, and the waste of one is used in the other.It saves energy as there is a lower requirement for non-renewable resources.It doesn't use agrochemicals.It involves methods that reduce soil erosion, like managing irrigation, covering the soil with tillage.What are its disadvantages?It takes more effort since the use of machines is minimal.Limited use of land and hence, mass production is not possible.What are the challenges?New farmers have to struggle with high labor demand since it involves less use of machines and hence more workers are required.Before harvesting their first crop, young farmers require a huge sum of up-front capital, which is even more for biologically diverse farms.

Hence the correct options are (c) and (e) higher initial costs;  increase labor costs.

Answers

Answer:

25% red

50% roan

25% white

Explanation:

When RR (red) is crossed with WW (white), it results in roan color.

       RR (red)   x    WW (white)

              RW (roan)

Two roan individuals are then mated.

          RW    x    RW

       RR    RW    RW    WW

Offspring

1/4 RR - Red

1/2 RW - Roan

1/4 WW - White

Hence, the offspring are expected to be 25% red, 50% roan, and 25% white.
