Answer: d. C (parent rock)
Soil horizons are the layers lying parallel to the surface or subsurface layers of soil. These horizons are formed in the process of soil horizon. These sequence of soil horizons is collectively called as soil profile.
The layer or soil horizon, which is least likely to be penetrated by plant roots is C horizon. The C horizon is a layer of soil, which consists of huge aggregates of parent rocks, which are unweathered or partially weathered, lying deep in the bottom of the soil profile. It does not contain organic matter. Also, the texture of the soil is not fine, instead hard rocks are present. Therefore, this layer of soil cannot be penetrated by plant roots.
Answer:
protein hormone that tells animal cells to store blood glucose as glycogen is Insulin.
Explanation:
Insulin is a peptide hormone,secreted from the beta cell illets of langerhans of pancreas and then binds to the surface receptor of the target cell.
Insulin play an important role in the maintainance of blood glucose level, basically it helps to decrease the blood sugar level by activating the metabolic pathways that deals with the utilization of glucose such as glycogenesis or synthesis of glycogen from glucose.
Thus the extra blood glucose is stored in form of glycogen in both liver and muscle.
The nervous system is the major controlling, regulatory, and communicating system in the body. It is the center of all mental activity including thought, learning, and memory. Together with the endocrine system, the nervous system is responsible for regulating and maintaining homeostasis.
Answer:
The roots pulled up the food coloring with the water and it was transported through the xylem to the petals.
Explanation:
the xylem is one of the transport tissues in plants. It transfers water and nutrient from roots to stems and leaves.
The carbon in the plants and the rabbit is : Moving in and out simultaneously
<h3>The carbon cycle </h3>
The carbon cycle explains the reusing of carbon atoms which enters the earth from the atmospheres and its movement back to the atmosphere ( reuse ).
As the rabbit eats from the leafy plant the carbon it absorbs from the consumption of the plants enters into the atmosphere simultaneously. while as the leafy plants loses its carbon to the rabbit, carbon is added to the leafy plants from the atmosphere.
Hence we can conclude that The carbon in the plants and the rabbit is : Moving in and out simultaneously
