Describe how turning off the electric current in an industrial electromagnet affects magnetic fields

Answers

Answer 1
Answer:

Electromagnets are used in a number of everyday devices.

One useful characteristic of an electromagnet is the fact that you can vary its magnetic force by changing the amount and direction of the current going through the coils or windings around it. Loudspeakers and tape recorders are devices that apply this effect.Some electromagnets can be very strong and its power can be readily turned off and on. Junk yard electromagnets, common doorbells and electromagnetic locks are examples.Electromagnets can also be used to create continual motion when opposed by other electromagnets or permanent magnets. Examples include electric motors and maglev trains.

Why is carbon important

Answers

Carbon is very important because Trees take it (Co2) in in order for oxygen to be produced.

All plants for the most part take in Co2 so that they can produce oxygen,
and we need that oxygen to live , to pump blood into our lungs so we can roam around.

It is basically one of the main components of our every day life on Earth.

I really hope this helps you a lot.
carbon forms the key component for all known life on earth.

One of the ways that plant systems and tissues work together is in the transport of materials such as water, called transpiration. In transpiration, water is taken into the plant and then evaporates out of the leaves. First, water is taken in through pores in the dermal tissue of the roots and brought to the xylem of the vascular tissue. The vascular tissue then transports it up through the stem and into the leaves. Once in the parenchyma cells of the ground tissue of the leaves, photosynthesis and cellular respiration occur, using that water. The water is then released through guard cells of the dermal tissue into the atmosphere. Which of the following tissues and systems were involved in transpiration? Check all that apply. roots stem leaves dermal tissue vascular tissue ground tissue

Answers

Answer:

The correct answer will be-

Roots, stem, leaves, dermal layer, vascular tissue, dermal tissue and the ground tissue (All of them).

Explanation:

Transpiration is a process involved in the suction of the water from the ground tissue as transpiration is the loss of water from the leaves.

The transpiration begins with the absorption of the water from the soil through epidermis which is a part of the dermal tissue. The water is then transported through xylem which is a part of the vascular tissue in the stem. The water then reaches the leaves in parenchyma cells especially which is ground tissue and then is released through stomata a part of the dermal tissue.

Thus, all of them is the correct answer.

If Huntington’s disease is due to a dominant trait, shouldn’t three-fourths of the population have Huntington’s while one-fourth has the normal

Answers

Huntington's disease is due to an expansion of repeated CAG triplets (at 36 or more repeats) on the short arm of chromosome 4 in the HTT gene of huntingtin.

The prevalence in the Caucasian population is estimated at 1 / 20,000 to 1 / 10,000. This is higher compared to a disease with autosomal recessive inheritance.

It should be known that this disease affects only certain families where a heterozygote has a chance to transmit it (1/2), this is due to a mutation in their gene.

Despite its dominant character, it remains a rare disease due to its recent appearance (discovered in the 19th century) and also the rarity of the mutation.
