Answer:

Tubercle: allows tendons to attach to bone

Foramen: Allows blood vessels and nerves to travel through bone.

Fossa: Allows to bones to form a joint.

Explanation:

The tubercle or tuberosity in the human seletal system, is a protrusion that allows for attachment of skeletal muscles. The muscles attach by tendons, where the enthesis is the connective tissue between the tendon and bone.

Foramina inside the body of humans and other animals typically allow muscles, nerves, arteries, veins, or other structures to connect one part of the body with another.

What is the process that turns water vapor into liquid, which causes the formation of a cloud.?
garri49 [273]
The process of physical change in state, that occurs when water vapor or gas converts into a liquid is condensation. According to the kinetic molecular theory, the particles lose kinetic energy and slow down and thus become more arranged and have a definite shape but an indefinite volume, a liquid.

Why are some human activities harmful to nature?
Alja [10]

Answer:

Humans impact the physical environment in many ways: overpopulation, pollution, burning fossil fuels, and deforestation. Changes like these have triggered climate change, soil erosion, poor air quality, and undrinkable water.

A cell that is undergoing mitosis is examined with a light microscope. An observation that would allow for identification of the
Elan Coil [88]

<u>Answer</u>:

An observation that would allow for identification of the cell as an animal cell rather than a plant cell would be "the centrioles migrating".

<u>Explanation</u>:

Centrioles start moving towards the opposite ends of the cell, whereas the microtubules starts moving from the centrioles and gets attached to the centromeres of chromosomes. The microtubules that have been projecting from the centrioles on opposite poles of the cell are connected to individual centromere and further form into spindle fibers.  After the accumulation of chromatin into chromosomes in prophase, resulting in the breaking down of the nuclear envelope, or membrane. In case of animal cells, the centrioles present at the nucleus starts to separate and go to the opposite poles of the cell. As the centrioles transfer, a spindle is seen to be formed between them.

4. A single-celled organism that a student observed under a microscope is shown below.
Katyanochek1 [597]

Explanation:

D. The organism is eukaryotic because it has membrane-bound organelles.

Cells are the basic microscopic units of all organisms. There are two cell types, Prokaryotes and Eukaryotes.

Prokaryotic ( meaning pro: before and Karyon: for kernel/nut) describes organisms which don’t have a cell nucleus or other organelles surrounded by membranes. Eukaryotic  (eu meaning true), are organisms with a cell nucleus and several other organelles surrounded by membranes. Example prokaryotes do not contain: nuclei , Golgi apparatus, chloroplasts, mitochondria

<em>Both may contain a cell wall (seen in eukaryotic fungi and plant cells)</em>

<em />

Arranged in a phospholipid bilayer, the membrane is semi-permeable; allowing entry into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water and hydrophilic molecules to move across the membrane along the concentration gradient.

Their structural components (i.e. their makeup) determine their function (what they do) . For instance, photosynthesizing cells in algae and plants have structures called chloroplasts. These contain chlorophyll, a specialized compound which facilitates the conversion of light energy to energy stored in carbohydrates. In specific cell types, collected proteins may function as a unit called an organelle. Some organelles are bound by membranes like those that make up the external structure of the cell, with varying compositions of phospholipids and proteins. These are advantageous, as they:

  • may increase metabolic reaction efficiency; they allow cells to concentrates smaller fractions of enzymes and solutes
  • separate proteins and molecules that me harm the cell by parceling them into membrane-bound organelles for example, proteaseas bound within lysosomes can break down many structural proteins
