D. Vascular tissue
Vascular tissue is known to be a complex conducting tissue that is formed by the arrangement of multiple cell types in vascular plants. Thus, the transportation of minerals, water and other products of photosynthesis occurred through the vascular tissue which is transported throughout the plant. However, both xylem and phloem are primary component of vascular tissue.
Answer:
A larger number of synaptic vesicles releasing neurotransmitter at the neuromuscular junction compared with CNS synapses
Explanation:
B) Being around humans represented an advantage, so wolves were able to take advantage of that by changing their digestion to be able to eat wheat, rice, barley, corn, and potatoes.
C) Dogs mutated to be able to eat wheat, rice, barley, corn, and potatoes.
D) Some wolves may have had variants in their digestion that allowed them to eat wheat, rice, barley, corn, and potatoes and so were able to survive with humans.
Answer:
The correct answer will be option-D
Explanation:
The studies done by the scientist led to the conclusion that the doges were evolved from the wolves,
The interaction of the wolves with humans became symbiotic around 10000-15000 years ago when the wolves in search of food changed themselves and adapted to survive with humans.
The studies on the genes of Dog shows that the gene responsible to digest carbohydrate called amylase starting duplicating in Wolves allowing them to digest carbohydrate cereals offered by humans. Their pancreatic enzymes also got modified to digest the carbohydrate-protein rich cereals.
Thus, option-D is the correct answer.
Secondary consumers must eat more often or consume more prey to obtain the same amount of energy as primary consumers.
Secondary consumers usually eat a smaller quantity of food than primary consumers because they obtain their energy from consuming other organisms rather than directly from photosynthesis.
This means that a significant amount of energy is lost as it is transferred up the food chain. For example, only around 10% of the energy stored in plants is transferred to herbivores, and only around 10% of that energy is transferred to carnivores.
This means that the higher up the food chain an organism is, the less energy is available to it.
Therefore, secondary consumers must eat more often or consume more prey to obtain the same amount of energy as primary consumers.

Answer: D. A soil that is 10 percent sand, 80 percent clay, and 10 percent silt.
A soil is an aggregate of sediments that is obtained after weathering of rocks, and organic matter being added by the biological activities of the living beings like decomposition of dead and decaying organisms.
Clay is a type of soil that has fine grained particles, it has better minerals and water retention capacity than other soils like sand and silt. This makes the clay more fertile over other soils and will be suitable for gardening. Therefore, the soil composition having more amount of clay in the soil composition will be the best soil for gardening.
Hence, A soil that is 10 percent sand, 80 percent clay, and 10 percent silt is a correct option.
The answer is the Sympathetic nervous system as a Group of answer choices central endocrine sympathetic somatic parasympathetic shows these symptoms.
The sympathetic nervous system is a part of the self-sustaining fearful device which controls the involuntary frame capabilities such as coronary heart rate, breath rate, perspiration, etc. The sympathetic is in particular answerable for the boom withinside the feature of frame capabilities while the frame perceives a risk. When confronted with a risk or distress, the sympathetic nervous system initiates physiological reactions called the “combat or flight” response, thereby growing the frame’s alertness to such risk. Examples of improved frame capabilities or “combat or flight response” consist of improved perspiration and improved coronary heart rate, as exhibited via way of means of Blair.
The sympathetic nervous system directs the body's speedy involuntary reaction to risky or disturbing situations. A flash flood of hormones boosts the body's alertness and system coronary heart rate, sending greater blood to the muscles.
Hence conclude the sympathetic nervous system is the answer.

Answer:
sympathetic nervous system
Explanation:
The sympathetic nervous system is part of the autonomous nervous system which controls the involuntary body functions as heart rate, breath rate, perspiration etc. The sympathetic nervous system is specifically responsible for the increase in the function of body functions when the body perceives a threat. When faced with a threat or distress, the sympathetic nervous system initiates physiological reactions known as the “fight or flight” response, thereby increasing the body’s alertness to such threat. Examples of increased body functions or “fight or flight response” include increased perspiration and increased heart rate, as exhibited by Blair.
