B. mutualistic symbionts.
C. herbivores.
D. parasitic symbionts.


In general, more complex animals are

A. More likely to rely on chemical digestion than to rely on mechanical digestion
B. more likely to perform intracellular digestion than extracellular digestion
C. more likely to have one body opening than to have two body openings
D. more likely to have a digestion tract than to have a gastrovascular cavity

Answers

Answer 1
Answer: The cattle and the microorganisms are mutualistic symbionts. The correct option among all the options that are given in the question is the second option or option "B".

In general, more complex animals are more likely to have a digestion tract than to have a gastrovascular cavity. he correct option among all the options given is option "D". 
Answer 2
Answer:

Answer: 1. B. mutualistic symbionts.

Explanation:

A mutualistic symbiotic relationship is the one in which the two species lives in close association and both of the species obtains the benefit of living together.

Cattle depend on microorganisms in their digestive tract to digest the cellulose in their diets is the example of mutualistic symbiotic relationship. This is due to the fact that cellulose is a biomolecule which is obtain in leafy diets of the cattles. This is difficult to digest by the digestive system of the body of these cattles therefore, the function of digestion is performed by the microbes present in the digestive tract. Both of the organisms attains nourishment after this process.

Answer: 2. D. more likely to have a digestion tract than to have a gastrovascular cavity.

The complex animals are expected to have a complex digestive system. The gastrovascular cavity secretes digestive juices which aids in the process of digestion.

B. An oak tree grows from the seed material in an acorn.
C. Water drips from underneath an oak tree leaf in the morning.
D. Sediment from an area where oak trees were cut down builds up alongside a stream

Answers

The example that demonstrates that all cells come from pre-existing cells is an oak tree grows from the seed material in an acorn (option B).

What is the cell theory?

The cell theory is the scientific theory that all living organisms are made of cells as the smallest functional unit.

One of the components of the cell theory is that all cells come from already existing cells i.e. new cells form from cells that are already in existence in a process of reproduction.

The example of this is a tree that grow from a germinating seed. Hence, option B is correct.

Nitrogen fixation makes nitrogen gas useful to crops.

true or false

Answers

Answer:

True

Explanation:

The nitrogen fixation is a process that involves conversion of atmospheric nitrogen to nitrates in the soil. This process is mainly performed by nitrogen-fixing bacteria present in the soil.

The nitrogen fixation is important for plants and animals. The nitrogen present in the atmosphere cannot be used directly by animals and plants. The nitrogen is main constituent of chlorophyll that is required for the process of photosynthesis and for amino acids that synthesize proteins. Thus, Nitrogen fixation makes nitrogen gas useful to crops.
It is actually True!

Explain why carbon dioxide concentration is a limiting factor of photosynthesis

Answers

When carbon dioxide concentration is low, ATP and NADPH are made at a faster rate than CO2 can be fixed. This why CO2 concentration is a limiting factor.

Fungi are interesting organisms that interact with humans in many ways. Yeasts arefungi used in the food industry to produce products such as bread and certain beverages. Some fungi are valuable in medicine. For example, the drug cyclosporine, which is capable of suppressing the response of the immune system to foreign antigens, and the antibiotic penicillin are both products from fungi.
