Answer: Decomposer

Explanation:

Bacteria feed on the dead and decaying organism, in which they feed on them and obtain energy from them.

It is not a mutual relation because the host cell on which they feed is not alive. They eat the organic matter that is present in environment.

The bacteria and fungi clean the environment in this way. The dead plants and animals are decomposed in the environment and the nutrients get back  into the soil.

hence, the correct answer is option B

The thin segment of the nephron loop's descending limb ________. The thin segment of the nephron loop's descending limb ________
vovangra [49]

Answer:

The correct answer is ''aids in the passive movement of water out of the tubule''

Explanation:

The nephron loop has a descending branch, which goes to the renal medulla, and an ascending branch, which goes back to the cortex. The nephrons of these kidneys can have loops of Henle of different dimensions. The thin segment of the loop has thin epithelial membranes, its cells are highly permeable to water, but not to solutes. The water that exits from the descending portion of the nephron loop into the medullary space is immediately reabsorbed by the peritubular capillaries, causing osmolality to increase in both the tubular fluid and the medullary interstitial fluid. The characteristics of the descending branch differ from one species to another, the normal thing is that in one way or another, the osmotic concentration of the urine that moves through it is balanced with that of the interstitial fluid.

Which statement about the molecules in ice and water is correct?
Assoli18 [71]
The molecules in ice are close together and do not have any movement, or energy at all (frozen). The molecules in water are apart from each other and do have motion and energy. The molecule in gas or vaporization, are far apart from each other, have rapid movement, and have a great amount  of energy. Just think that the lighter the liquid state of matter gets, the more energy and motion it has.

klio [65]

Animals are associated with <u>phyla</u> and plants are associated with <u>divisions</u>

Answer: Option B

<u>Explanation:</u>

There are millions of organisms in the world. They were then subdivided based on the similarity between each groups.  

The Animal kingdom range from complex to simple animals. The kingdom Animalia is further subdivided into Phyla. The phyla is further classified into vertebrates and invertebrates.  

Plants acquire nutrition by photosynthesis. They are autotrophs preparing their own food. Animals can’t prepare their own food hence they directly or indirectly depend on the plants for food. The plant kingdom is subdivided to plant divisions.

1. Get a flashlight and switch it on.
Anna [14]

Answer:

Explanation:

1. The beam emitted travels along a straight path and it is divergent in nature. It has its radius increasing progressively as the distance away from the source of light increases.

2. It would be observed that the region where the bulb is positioned has denser light beam. This gets fainter towards the edges of the beam and away from the bulb.
