Answer:
is the car's acceleration.
Explanation:
Initial velocity of the driver = u = 14 m/s
Final velocity of the driver = v = 5.5 m/s
Duration of time in which 14 m/s velocity is changed to 5.5 m/s = t = 6.0 s
Acceleration of the driver = a
Using first equation of motion: v = u + at
Negative sign indicates the that is deceleration is occurring that is speed of the car is decreasing.
Answer:
1st option
Explanation:
they adapt throught genetic variations
The answer to this question is Vitreous Body. The Vitreous
Body is a jelly form substance that fills the space on the eyeball of humans.
The vitreous body also helps transmit light in the retina and this also
functions to help maintain the shape of the eyeballs and make it stay in place.
Although there are mesophile archaea (live in mild conditions), most of the archaea live in extreme conditions (e<span>xtremophiles). These extreme conditions may be related to high salt concentrations (halophiles), high temperatures (thermophiles), very alkaline conditions (alkaliphiles), or very acidic conditions (acidophiles).
In order to regulate homeostasis:
Halophiles </span><span>uses aerobic respiration in waters that can go up to 25%NaCl concentration.
Thermophiles have </span>heat shock proteins whose purpose is to refold denatured proteins to their functional conformation. These heat shock proteins also restore damaged proteins. There are several other mechanisms aiming to protect DNA. For example, some archaea have a protein that stabilises the DNA double-helix conformity raising its DNA melting point by 104ºF. Also, the cell membrane structure is heat-resistant - instead of simple phospholipids, their membranes are made of di-bi-phytanyl diether lipids.
Acidophiles can use carbon dioxide for as a carbon source. They can also, for example, in environments with oxygen process organic molecules by using TCA cycle reversely in order to convert sulfur and oxygen into sulfuric acid.
Answer: The following statements are true about plant cells-
-They have a cell wall
-They have the same functions
Explanation:
A cell wall is present in a plant cell to keep its structure and rigidity. They are made from cellulose.
All plant cells have a nucleus, ribosomes, mitochondria and cell membrane and they all have the same functions as they would have in an animal cell.
Statement 1 is false as plant cells are eukaryotic, which means they have a nucleus.
Statement 2 is also false because a plant cell needs a cell membrane to separate the vacuole and the organelles.
Hope that helped :)
