C, because it makes the most sense hoped this helped !!!!!
After the macrophage fails the Helper T Cell stimulates the B cells if pathogen is extracellular and Cytotoxic T Cells if the pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.
Fire naturally occurs in a grassland ecosystem and it helps the environment stay healthy and strong. I promotes richer soil as well as gets rid of excess leaves scattered around. After a fire, grassland ecosystems can grow again and be better than they were before.
Answer:
A 0.015M
Explanation:
Molarity, which refers to the molar concentration of a solution, can be calculated using the formula:
Molarity (M) = mole (n) / volume (L)
Based on the information provided in this question, the solution contains 0.83 g of dissolved KCI.
We can calculate the number of moles of KCl in the solution by using the formula:
Mole = mass ÷ molar mass
Where atomic mass of; K = 39, Cl = 35.5
Molar Mass of KCl = 39 + 35.5
= 74.5g/mol.
Mole = 0.83g/74.5g/mol.
mole = 0.01114
Approximately, n = 0.011mol
Hence, molarity = 0.011mol/0.75L
Molarity = 0.0146
Molarity = 0.015M
Answer:
There are 3 methods to set up a wildflower classification means discovering a new flower. Those methods are discussed below in the explanation section.
Explanation:
Method one (Identification tools using):
- Search the about of the flower in the flower dictionary or flower database.
- Use any app which can identify flower such as Flowerchecker, Naturegate, etc.
- Take photos of the plant and post it on Flicker to get more information.
- Try google photos for searching about the plant by its picture.
Method two( Measuring the physical character of the plant):
- Measure the overall height of the plant.
- Measuring the width of the plant.
- Look at the flower to check how the flower is arranged on the stem.
- Count the petal number of the flower.
- Identify the color of the petals.
- Check the shape and texture of the stem.
- Check the shape, size, and arrangement of the leaves in the plant.
- Use this collected information to identify the flower in a plant database or encyclopedia.
Method three (Identifying the Flower’s Location and Blooming Time):
- Use the climate and terrain to determine the type of the flower.
- Observation of the factors in the geographic location to identify the flower.
- Find out the time of year when the flower bloomed.
- Identify the flower in an online database or encyclopedia using the collected information.
By doing this, you can set up a wildflower classification key and can find out the kingdom, family etc of the flower.
