How does a virus cause disease?
nika2105 [10]

Answer:

Viruses are like hijackers. They invade living, normal cells and use those cells to multiply and produce other viruses like themselves. This can kill, damage, or change the cells and make you sick. Different viruses attack certain cells in your body such as your liver, respiratory system, or blood.

Explanation:

Viruses tend to target specific tissues (cells) in the host.

For example, the influenza virus has a predilection for the respiratory tract, hepatitis viruses target the liver, polio virus targets the motor neurons of the spinal cord and rotavirus multiplies in the gut. Symptoms of a viral infection may be subtle and nonspecific or specific and suggestive of the causative agent.

Dengue virus, Ross river virus, measles and rubella infections are associated with fever and a widespread red rash, chicken pox and herpes simplex viruses are associated with blistering, often localized, rashes; and hepatitis viruses cause liver damage and jaundice.

Bacteria tend to be less tissue-specific and non-discriminatory than viruses and can cause a variety of infections once they have invaded the host.

These bacterial infections are often manifested by the presence of pus wherever the bacteria settle, and systemic symptoms such as fevers, chills, pain, swelling and loss of function occur when bacteria invade and multiply.

In hamsters, we can examine the genes for coat color and eye color which are linked:B = brown coat, b = white coat, G = green ey
Inessa [10]

Answer:

10.2 cM

Explanation:

Given,

pure breeding parent 1 : BBgg = brown coat and pink eyes

pure breeding parent 2 : bbGG = white coat and green eyes

BBGG X bbgg = F1 = BbGg ( All are brown with green eyes )

When F1 progeny is test crossed with white coat and pink eyes hamster:

BbGg X BbGg = F2 =

brown, pink eyes = 99 = parental

white, green eyes = 103 = parental

brown, green eyes = 12 = recombinant

white, pink eyes = 11 = recombinant

Recombination frequency =

(total number of recombinants / total progeny ) * 100

= [( 11 + 12 ) / ( 99 + 103 + 12 + 11 )] * 100 = (23/225)*100 = 0.102 * 100 = 10.2 %

1 % recombination frequency = 1 cM distance between genes

Hence, the distance between B and G gene is 10.2 cM

1. Zach made a chart to show how many mm his plant grew each week for 7 weeks. Each block equals 5 mm of growth. How tall is the
yulyashka [42]

The given question is missing the chart or the details of blocks, each week. However, the details of the blocks are as follows:

1week = 2blocks

2weeks = 3blocks

3weeks = 5blocks

4weeks = 4 blocks

5weeks = 5blocks

Oweeks = 5blocks

7 weeks = 3blocks​

Answer:

The correct answer is - 13.5 cm.

Explanation:

According to the details of the blocks, the number of blocks each week as follows:

1week = 2blocks

2weeks = 3blocks

3weeks = 5blocks

4weeks = 4 blocks

5weeks = 5blocks

Oweeks = 5blocks

7 weeks = 3blocks​

Adding total blocks would be :

2 +3 + 5 + 4 + 5 +5 + 3 = 27 blocks

Each block equals 5 mm of growth.

Then, 27 x 5 = 135 mm

135mm = 13.5 cm

Thus, the correct answer is : 13.5 cm
