Answers

Answer 1
Answer: 1. Protozoa are single celled, eukaryotic organisms that exhibit animal-like behaviour.2. Viruses consists only of genetic material and a protein coat, and they are known to cause a wide variety of diseases such as AIDS.3. Fungi have characteristics similar to plants, but they do not have root systems like plants do and they also do not rely on chlorophyll to photosynthesize.4. Bacteria make up this category.5. Rickettsiae is a genus of bacteria that are intracellular parasites.

B. photosynthesis
C.respiration
D.Weathering

Answers

Answer:

A. decomposition

Explanation:

Decomposers are microorganisms such as bacteria, fungi and worms. These organisms are significant decomposers which can break down most types of organic matter. All the living organisms are made of carbon. They all require carbon their growth and reproduction. Decomposers decompose dead organisms and use the carbon dioxide released from them for their food. Therefore, decomposers help in cycling of carbon from dead bodies into the atmosphere through cellular respiration.

What are the functions of micronucleus and macronucleus in paramecium?

Answers

The macronucleus is the larger elipse-shaped nucleus and takes care of functions like respiration and digestion. In contrast to this, the smaller micronucleus is only involved in cell division or reproduction.

Answer: the micro nucleus regulates the vegetative functions in the macro nucleus regulates reproduction in paramecium.

Which word belongs in a different group than the group below?brain, glands, motor neuron, movement, muscles, sensory neuron, stimuli

brain
motor neuron
glands
stimuli

Answers

Answer:

In the group of a brain, motor neuron, glands, and stimuli, the glands can be considered as an odd one out.

It is because the brain, motor neuron, and stimuli come under a common biological system which is termed as a nervous system.

A nervous system is a network or complex of nerve cells that perform the function of transmitting nerve impulses from one body part to another.

It consists of a brain, spinal cord, and different types of nerve cells (such as sensory nerves, motor nerves et cetera).

In contrast, a gland is defined as an organ of cells which synthesize and release chemical substances (such as hormones, enzymes et cetera) either into the bloodstream (endocrine glands) or into the body cavities (exocrine gland).

Thus, the gland can be considered as the odd one out.
