Answer:
2. This gives the worms two separate populations of offspring that have different chances of surviving. An added benefit of being a hermaphrodite is that if a worm never finds a mate, it can fertilize its own eggs and reproduce that way. Many hermaphrodites experience this benefit.
3. Surprisingly, earthworms have quite a few digestive organs in common with humans. Digestion starts in the mouth, which takes in soil. The food is then transferred to the pharynx, which swallows the dirt into the esophagus. Instead of a stomach, earthworms have a crop which stores food and connects to the gizzard.
Explanation:
4. Worm castings contain the worms' gut bacteria and mucus. These microbes and substances are very helpful to plants. Vermicompost has more nitrogen-fixing bacteria than conventional compost. Vermicompost helps make minerals in the surrounding soil available to plants more quickly.
5. Comparative anatomy is an important tool that helps determine evolutionary relationships between organisms and whether or not they share common ancestors. Anatomical similarities between organisms support the idea that these organisms evolved from a common ancestor.
Answer:
An object in motion stays in motion unless an external force acts on it.
Explanation:
Newton's first law, the law of inertia, states that an object will remain at rest or in motion unless acted upon by another force.
Answer:
stored solar energy in phytoplankton, zooplankton, and other organic material
Explanation:
The energy in fossil fuels comes from the sun, which drives photosynthesis to change carbon dioxide and water into the molecular building blocks of ancient plants and animals.
Parenchyma is the answer because whereas the other two, xylem and phloem are vascular tissues, parenchyma is a packing tissue.
Answer:
A,C E
Explanation:
The inner membrane of the mitochondria separate the matrix of the mitochondria from the cytosol(inner membrane space.). It is invaginated folded inwards to form the critae. This is an adaptive feature to increase the surface area for biochemical reaction in the mitochondria.
The invagination gives two compartments the inner mitochondria also creates the outer intermembrane space and the inner matrix
These are the substances that can pass freely the inner membrane of the mitochondria.Pyruvate and H+ can not pass through.Specifically,it is not preamble to H+ because, hydrogen ions are needed to generate the electrochemical gradients needed for the chemical energy for phosphorylation of ADP by P to form ATPs by the enzyme ATPase synthase.If the inner membrane is permeable to H+ the electochemical gradient will not be produced, and therefore ATPs productions stops.
O2 needs to pass through the inner membrane because it it the final electron acceptor. Therefore if not allowed to pass through oxidative phosphorylation and ETC will nor occur.
CO2 must pass through because its accumulation will increase the acidity of the inner mitochondria
