Biology
1 answer:
monitta2 years ago
6 0

Answer: In cell biology, an organelle is a specialized subunit, usually within a cell, that has a specific function. The name organelle comes from the idea that these structures are parts of cells, as organs are to the body, hence organelle, the suffix -elle being a diminutive

Solids will usually sink when placed in their own liquids. Which is an exception?
Marat540 [252]

WATER

Solids will usually sink when placed in their own liquids with the exception of water

Explanation:

Ice (the solid form of water) floats on water that is cooler than 4 degrees centigrade. This is unlike any other material and this phenomenon has been referred to as the ‘water anomaly’.

Most substances will sink in their own liquid because the solid form is denser than the amount of their own liquid that they displace when immersed. This is because the particles in the solid are closely packed together hence there are more particles per volume than in the liquid form.  

Water however, expands at temperatures below 4 degrees and hence ice is less dense than water at 4 degrees and below. The particles in ice are farther apart than particles of water at 4 degrees and below. There is, therefore, more particles per volume in the liquid form of water than in ice – making ice less dense.

Which of these tasks would a hydrologist be most likely to perform?
GuDViN [60]

Hydrologists are most likely to perform actions relating to estimating the amount of groundwater in an aquifer.

<h3>Hydrologists</h3>

Hydrologists are scientists that specialize in the study of how water relates to the various crusts of the earth.

Hydrology in itself refers to the branch of science that studies how water moves relative to the earth's crusts.

Thus, species identification, age of fossils, or extracting underground oils have nothing to do with the work of hydrologists.

9) Identify the FALSE statement regarding sensory receptor cells. A) A graded potential is referred to as a receptor potential.
rjkz [21]

Answer:

<u> C) Each type of sensory receptor responds only to the stimulus that defines the receptor</u>

<u></u>

Explanation:

Neurons,  specialized cells within the nervous system. These help with coordinated movement ad communication within the body through the transmission of electrical signals.

Sensory receptors are highly specialized neurons. These are able to detect various chemical and physical stimuli, and are classified by their ability to detect certain stimuli such as:

  • photoreceptors
  • mechanoreceptors
  • chemoreceptors
  • thermoreceptors

Sensory receptors respond to certain intensities of stimuli, instead of one specific stimulus. e.g. Mechanoreceptors within the skin can respond to pressure changes due to touch, but may also detect sound due to specific vibrations.

A cell found in the root of the plant would most likely lack what cell structure.
mestny [16]

Answer:

The cells found in the root of the plant normally lacks chloroplasts, as roots do not perform photosynthesis. The main function of chloroplast is photosynthesis.

Explanation:

The plant cell contains nucleus, cell wall, cell membrane, mitochondria, chloroplasts, vacuole, endoplasmic reticulum, ribosomes etc. Chloroplasts contain green pigments which give green color to the plants. The main function of chloroplast is photosynthesis. During photosynthesis, the plants produce glucose and release oxygen by using carbon dioxide from the air, and absorbing water and nutrients from the soil. Using the glucose in the plants and oxygen, mitochondria produce energy.

The root system of the plants absorb water and nutrients from the soil. The absorbed water and nutrients are then transported to various parts of the plant to carry out processes like photosynthesis, maintaining turgor pressure etc. They have different types of cell which perform some specific functions. These cells also contain cell wall, cell membrane and mitochondria. Mitochondria provides energy for the active transport of water and nutrients. But chloroplasts are absent in root cells as they do not perform photosynthesis.
