Fungal infections are often difficult to treat because fungi a. can use different modes of movement to move themselves away from any medicine that's harmful to them. b. can reproduce either sexually or asexually to avoid some types of medicine. c. can change their cell walls to develop antibiotic resistance. d. and animals are closely related and are both eukaryotic. many medicines that treat fungal infections are also harmful to animal cells.

The answer is D

Explanation: This is because fungus are Eukaryotic unlike bacteria.  

The correct answer will be option D.

Explanation:

Fungal infection are the infections caused by the fungi which are less common than infection caused by bacteria.

Fungi attack animals by direct colonizing and destroying the tissues and result in mycosis. Many fungal infections occur on the animal's skin.

Although rare, they are very difficult to treat as they are closely related to eukaryotic organisms and the compound that kill the fungi also harms the eukaryotic animal host. Additionally, antibiotics target only prokaryotic cells and not eukaryotic organisms. So, this limits the medical treatments that can be used against them.

thus, option D is the correct answer.

americans began to notice growing differences between the northern and southern sections of the country. there were more people living in cities in the north, which made it more urban. more people lived on farms in the south, which made it more rural. while many people were farmers in the northern states, there were now other ways to make a living, such as working in mechanical cotton gins factories manufacturing cloth, tools and other goods. people in the north supported high tariffs on goods imported from europe because the extra cost encouraged people to “buy american” instead. in the southern states, planters did not like tariffs because they sold most of their production to europe and bought their tools from there as well. southerners believed the protective tariff was something that only northern factory owners keep their profits high. so the southern politicians came up with an idea. they would opt out. they would simply ignore the protective tariff. it was ‘null and void’ in south carolina. the state would not collect the taxes on goods imported into south carolina, no matter what the president said they had to do. this decision led to the nullification crisis.

measuring light intensity

light meters can be used to measure light intensity. the meter is held at the soil surface and pointed in the direction of the maximum light intensity, and then the meter is read.

errors can be made when measuring light intensity by accidentally shading the light meter. the reliability of the results can be checked by taking many samples.
