Soil is a complex mixture of minerals, water, air, organic matter, and countless organisms that are the decaying remains of once

-living things.
Soil covers the ground and is an important ingredient for plant growth. However, soil must be formed. The picture shows the soil formation process.

Which statement best describes the process of soil formation?

A) Rain gets into cracks in rocks. When the rain freezes, ice forms. Rocks begin to erode and decay. These processes provide organic and mineral matter for soil.
B) Rain gets into cracks in rocks. When the rain freezes, it fills the cracks with ice. The water dissolves the minerals in the rock, releasing them into the soil.
C) Rain gets into cracks in rocks. When the rain freezes, the cracks expand. The ice preserves dead organic materials. These processes release minerals into the soil.
D) Rain gets into cracks in rocks. When the rain freezes, the cracks expand. The rock begins to break down by the process of weathering, releasing minerals into the soil. Small plants and microorganisms also loosen the rock and when decayed, provide organic material.

Igoryamba

Answer:

The correct answer is ''All of the choices are correct.''

Explanation:

Pregnant women are a risk group for listeriosis, the disease caused by the Listeria monocytogenes bacteria found in contaminated food. This organism can cross the placenta and affect the fetus. Due to the decrease in cellular immunity, pregnant women are part of the population at risk and are 17-20 times more likely to develop listeriosis after the consumption of contaminated food and it usually occurs from the third trimester and appears as a disease mild with not very high fever, joint and muscle pain. Listeriosis can cause miscarriages during the first three months of pregnancy. As the third trimester is reached, the mother is at greater risk. It presents a 40-50% fetal or neonatal mortality. In the first or second trimester it produces septic abortions and intrauterine fetal death, in the third trimester she produces chorioamnionitis and premature labor. In 1/3 cases it can occur asymptomatically in the fetus / neonate. In newborns, listeriosis can cause blood infections and meningitis.

SSSSS [86.1K]

Answer:

The correct answer is option d)"the percentage of pink flowers should increase over time".

Explanation:

In this study it is stated that two factors affect the flower coloration of <em>Claytonia virginica</em>: slugs preference of eating pink-flowering plants and bees preference of pollinating pink-flowering plants as well. If the researcher removes all slugs from the study population we can expect that the percentage of pink flowers should increase over time. The removal of the predator that prefers eating pink-flowering plants will favor the reproduction of this type of plants, which are also favored by bees pollination preference.

Based on the scenario below, select the statement that accurately finishes the sentence.
Furkat [3]

Answer:

A. damaged her peripheral nervous system because the information regarding taste cannot be transmitted back to her brain.

Explanation:

The nervous system is an important system of our body and is directly related to our survival. This system is linked to the coordination of the organism's various activities and is also responsible for allowing the interpretation of the environment around us.

The nervous system is an important system of our body and allows us to have emotions, to remember an important moment in our lives, to interpret smells, tastes and images, to make movements and even to stay alive through the automatic breathing and heartbeat.

Taste, that is, the sense of taste is directly linked to the peripheral nervous system. For this reason, if Stacey has lost her sense of taste, we can conclude that she has damaged her peripheral nervous system because taste information cannot be transmitted back to her brain.
