what happens when a cold front replaces a warm front
Answer:
When a cold front overtakes a warm front, it creates what's called an occluded front that forces warm air above a frontal boundary of cooler air masses.
Explanation:
The presence of a cold front means that cold air is advancing and pushing underneath warmer air. This is because the cold air is ‘heavier,’ or denser, than the warm air. Cold air is thus replacing warm air at the surface.

Why are seeds an evolutionary advantage for seed plants?
Seeds allow for the transport of water and nutrients.
Seeds develop into adults without s x u a l reproduction.
Seeds protect the plant embryo and its food source.
Seeds provide the materials for photosynthesis.
The seeds an evolutionary advantage for seed plants because seeds develop into adults without sxual reproduction which means letter B.
What is the evolutionary importance of the seed?Seeds play an important role in the dispersion of plant species, that is, they ensure that plants spread throughout the environment. In addition to guaranteeing a greater area of domain for the species, competition between the newly born plant and the mother plant is also avoided.
Seeds allow the expansion of a type of plant around the world in addition to being a form of asexual reproduction that makes it unnecessary to join gametes.

Describe the structure and the function of the stomach. Be sure to include cells and tissues relating to this organ.
Connective tissues support the tissues of the mucosa and connect it to the muscularis layer.
The blood supply of the submucosa provides nutrients to the wall of the stomach. Nervous tissue in the submucosa monitors the contents of the stomach and controls smooth muscle contraction and secretion of digestive substances.
What is the function of the stomach?The stomach secretes acid and enzymes that digest food. Ridges of muscle tissue called rugae line the stomach.
The stomach muscles contract periodically, churning food to enhance digestion. The pyloric sphincter is a muscular valve that opens to allow food to pass from the stomach to the small intestine.
Thus, this could be the answer.

Nitrogen is present in the environment in abundance but still we cant inhale nitrogen
What is the role of nitrogen in our body?
Nitrogen is physiologically inert. It contributes nothing to the functioning of our bodies. The cells in our body need oxygen to live, not nitrogen. we can find nitrogen in our body in form of nitrogeneous base in nucleotide.
We inhale all gases present in air fills our alveoli, by the process of diffusion, only oxygen in the air is taken into the blood stream while the other gases along with the waste CO2 is exhaled. So you do breathe in nitrogen, but it is exhaled as it is by the body.
