Answer:
a. When the foot rolls OUTWARD
Explanation: is correct
Soil composition would be best for availability of nutrients, water, and root development higher proportion of humus; lower amounts of clay and sand
Compared to the lower soil layers, the topsoil or surface soil often includes more organic matter and air but less clay. The topsoil typically has the highest concentration of plant roots and is more fertile than the other layers.
- Nutrient management includes managing the composition of the soil. Minerals, organic material, water, and air are the fundamental elements of soil. Typically, 45% of the soil is made up of minerals. 5% organic material 20–30% water and 20–30% air are used. At best, these percentages are merely generalizations.
- Numerous nutrients are found in soil, which are obtained from dead plants and animals. The plants eat these nutrients as nourishment. So soil contributes to the growth of plants by giving them sustenance in the form of nutrients.

The answer is; D
Carbon dioxide and methane are potent greenhouse gases. They cause heating of the lower atmosphere, by trapping sunlight, that results to climate change. Due to the higher melting and boiling temperatures of phosphorus, it is rare that it occurs as gas in room temperatures. Phosphorus, therefore, does not pose a great threat of climate change.
Unoxygenated blood from veins enters the right atrium then it goes down to the right ventricle then out through the pulmonary artery to the lungs where it becomes oxygenated blood which then enters the heart through the pulmonary veins and it goes to the left atrium and then is pumped down to the left ventricle and out through the aorta to the arteries where it travels to different organs and becomes deoxygenated and then the cycle repeats itself.
Answer:
False
Explanation:
Prokaryotes do not have a nucleus.
This means their DNA is not enclosed in a nucleus and instead is in the cytoplasm.
On the other hand, eukaryotes have nuclei, so their DNA is enclosed within a nucleus.
So, this statement is false.
