someone help me with this question please: What is the job of ribosomes? Please answer as soon as possible its related to my project which is due on the day after tomorrow.
Answer:
Production of proteins
Explanation:
Ribosomes consist of RNA's and special proteins that help to synthesize other proteins. Ribosomes can be found either floating within the cytoplasm or attached to the endoplasmic reticulum. They
When you want to move a part of your body, your brain sends a signal to
the muscles....
The muscles Contract and relax randomly
Contract and pull on bones directly
Contract and pull on tendons, which pull on the bones
Answer:
Contract and pull on tendons, which pull on bones
Explanation:
Muscles don't attach directly to bones. The tendons throughout our body serve as a connective tissue, connecting the two. Skeletal muscles, which seem to be attached to bones, are still only held there with the help of muscles.
What happens to air pressure as the altitude increases?
O It gets lower
o It gets higher
0 It stays the same
Answer:
Pressure with Height: pressure decreases with increasing altitude. The pressure at any level in the atmosphere may be interpreted as the total weight of the air above a unit area at any elevation. At higher elevations, there are fewer air molecules above a given surface than a similar surface at lower levels.

-Calculate the fluid pressure at Piston A.
-Calculate the force exerted on Piston B.
-Which principle is being applied? What does the principle state?
Show all your work!
Answer:
80N
Explanation:
in both sides, pressure is the alwyays the same whatever the area is..
First we calculate the pressure at piston A:
P= F÷a
given that,
#F= 20N
#a=1m^2
P= 20÷1
P= 20 Pa.
At piston B:
pressure is the same = 20Pa
Area= 4m^2
P=F/a
F= P×a
F= 20 × 4
F= 80N
how are algae cells different from other cells
Answer:
In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.
Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.
Some characteristics of algae cells are:
• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.
By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.
• The cell wall is made up mainly of cellulose and glycoproteins.
• In the algae cells we can find different reserve substances produced by metabolism.
The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.
These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.
• They have structures of locomotion called flagella.
In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.
Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.

Observe: Click Next. What happens in the cytoplasm?
Answer:
The cytoplasm is a jelly like substance that supports and suspends organelles and molecules inside the cell. It also helps move and dissolve materials throughout the cell including waste molecules, proteins, and hormones.

Students in Mr. Painter's science class studied samples of pond water using a microscope. To prepare for the experiment, the students placed a drop of pond water on each microscope slide, and then covered the drop with a cover slip that was marked with a 1 mm grid. Using the microscope to view the slides, students counted how many of each type of organism they found in each 1 mm square. Finally, each student calculated the total number of each type of organisms. Their data is shown below. Which organism is the least plentiful in the pond water studied? A. amoeba B. volvox C. euglena D. paramecium
Answer:
Euglena
Explanation:
the least plentiful organism in the pond water studied. Each student found fewer euglena than any other organism.
