A precipitin test is used to distinguish between animal
and human blood.

Answers

Answer 1

Answer:

The standard test used to determine whether blood is of human or animal origin is the precipitin test. This test is based on the fact that when animals (usually rabbits) are injected with human blood, antibodies are formed that react with the invading human blood to neutralize its presence.

Answers

It can change the size of fish remaining, as well as how they reproduce and the speed at which they mature. When too many fish are taken out of the ocean it creates an imbalance that can erode the food web and lead to a loss of other important marine life, including vulnerable species like sea turtles and corals.

What is the function of spines on cacti

Answers

The spines of the cactus have several functions, which are the following:

To defend them from possible predators: inside the body of the plants there is a great deal of water; if herbivores could access it, these plants would not survive.

To provide them with shade: it is true that not much, but it is enough so that the loss of water by evaporation is minimal.

Reflect sunlight: many species have white spines.

ri

Answers

The equivalent depth of water in the soil is 180 mm of water and the volumetric water content of soil is 3870 cubic meter/ 1.5 hectare of soil.

What is the formula to calculate the equivalent depth of water in a soil?

The equivalent depth of water in a soil is calculated using the formula below:

equivalent depth of water = water content × depth of soil

The depth of soil profile 1 = 400 mm

The depth of soil profile 2 = 600 mm

Equivalent depth of water in the soil = 15% × 400 mm + 20% × 600 mm

Equivalent depth of water in the soil = 60 mm + 120 mm = 180 mm

Therefore, the equivalent depth of water in the soil is 1800 mm of water.

The volumetric water content of the soil is calculated using the formula below:

Volumetric water content = water content × bulk density of soil/density of water × height of soil

Height of soil profile 1 = 0.4 m

Height of soil profile 2 = 0.6 m

Volumetric water content of soil profile 1 = 15% × 1300/1000 × 0.4 m = 0.078 cubic meter/square metre of soil

Volumetric water content of soil profile 2 = 20% × 1500/1000 × 0.6 m = 0.18 cubic meter/square metre of soil

Sum of volumetric water content of soil = 0.078 + 0.18 = 0.258 cubic meter/square metre of soil.

1 hectare = 10000 square metre

Thus, 1.5 hectares = 15000 square metre

Volumetric water content of soil = 0.258 × 15000 cubic meter/ 1.5 hectare of soil

Volumetric water content of soil = 3870 cubic meter/ 1.5 hectare of soil

Thus, the equivalent depth of water in the soil is 180 mm of water and the volumetric water content of soil is 3870 cubic meter/ 1.5 hectare of soil.

Question:9. What type of weather front would be responsible for the following forecast: “A period of heavy rain within the next 24 hours followed by warmer temperatures. Thunderstorms and possibly thundersnow from the period of 24 to 30 hours from now with temperatures dropping by 20-25˚ F and barometric pressure dropping by 15-20 mb. Snow beginning 30-36 hours from now, accumulation of 10-13 inches possible. Cooler temperatures and clear skies in 2 days.”

Answers

The type of climate front would be responsible for the forecast is a warm front followed by a cold front.

Hot front

A warm front has warm, moist air behind it. This warm air rises above the cold air because it is less dense and forms clouds along the front. As the warm front approaches, there is a greater drop in pressure and cloudiness, the temperature remains constant or rises slowly, unless it drops a little because of the rain.

Cold front

In a cold front, warm air is pushed out and replaced by cold air. As in the case of the warm front, the vertical structure of the hot air will determine the reactions with reference to cloudiness and precipitation. As a common cold front approaches there is heavy rain and there may be strong gusts of wind or violent storms. With the passage of the front, there is an increase in pressure, a sudden and large drop in temperature, an increase in the strength of the wind and a variation in its direction.

Whit this information ,we can conclude that the type of climate front would be responsible for the forecast is a warm front followed by a cold front.
