Answer: False
A lake is a water body that is surrounded by land. The water in the lake comes from melting glaciers, rain, groundwater, rivers. Lake formation also occurs when a water body is restricted to it's natural flow. Erosion due to wind and water will limit the life of lake. As, soil removed during landslides or mudslides from hills or mountains get settled as debris at the bottom of lake will cause water pollution. Also, soil coming from agricultural field through water will carry in it fertilizers ,which will promote excessive plant and algal growth in lakes therefore, oxygen content of lake water will decrease which lead to death of animals residing in lake hence, will ultimately lead to water pollution ,which will be responsible for limiting the life of lake.
Answer: the atoms are istopes
Explanation:
Answer:
b. pseudocoelom
Explanation:
A pseudocoelom is a false body cavity of some invertebrates which occupies the space localized between the mesoderm and the endoderm of the gut. This false cavity is found in nematodes.
Arthropods exhibit:
1- Bilateral symmetry because both opposite sides of the body are similar,
2- they are protostomes because the blastopore becomes the mouth during embryonic development,
3- they have true tissues because tissues are formed by groups of cells which share a common function, and finally,
4-arthropods are triploblastic because they are formed by three germ embryonic layers (endoderm, mesoderm and ectoderm).
Your heart muscle needs its own supply of blood because, like the rest of your body, it needs oxygen and other nutrients to stay healthy. For this reason, your heart pumps oxygen-rich blood to its own muscle through your coronary arteries.
