A strain of fruit flies lacks the ability to produce Dicer- 2 protein. You might expect this strain to be more susceptible to <u>A. viral</u> infections.
Infections happen when a microorganism enters someone’s body and causes damage.
The microorganism makes use of that person’s body to sustain itself, reproduce, and colonize. These infectious microscopic organisms are referred to as pathogens, and they can multiply quickly. Examples of pathogens consist of:
- microorganism
- viruses
- fungi
The immune system is an effective barrier to infectious sellers. but, pathogens might also every so often overwhelm the immune system’s capacity to fight them off. At this level, contamination turns into danger.
A few pathogens have little impact in any respect. Others produce pollutants or inflammatory materials that cause negative responses from the body. This alteration manner that a few infections are mild and barely important, whilst others may be excessive and existence-threatening. A few pathogens are proof against the remedy.

Answer:
The answer is 6.8 meters.
Explanation:
During the S phase of the cell replication, the DNA is doubled before the division of the cell which means that it is twice it's original length.
At 0.34 nanometers, 3 billion base pairs (3.000.000.000) comes up to 3.4 meters and during the S phase the length is doubled so it is 6.8 meters long.
I hope this answer helps.
Sporophyte generation - It is found in both seed and seedless plant. Dominant phase of the life cycle of the seedless plants is diploid sporophyte while in seed plant male and female gametes fuses to produces a diploid zygote which develops into a sporophyte.
Pollination - It occurs in seed plants only
Sporophyte contains male and female reproductive structures - It is found in both seed and seedless plant.
Single fertilization - It occurs in both seed and seedless plant
Sperm cells transported by water to egg cells - seedless plant only
Answer: La célula es básicamente la unidad estructural funcional y biológica de todos los organismos.
Explanation: Ciencias
The correct answer is: oxygen and nutrients.
Ocean abiotic factors are non-living factors that influence an ocean ecosystem.
Nutrients are substances that ocean organism obtains from their environment in order to grow and live such as nitrogen, phosphorus, sulfur, carbon, iron, potassium, magnesium.
Oxygen is a necessary element required for respiration (most ocean organisms are aerobic), metabolism and other chemical reactions within the organism. Oxygen in the ocean is produced by algae and phytoplankton via photosynthesis.
