When animals are deprived of oxygen they die.
Explanation;
Oxygen is an important gas in any animal's life. Animals need it to survive.
Oxygen is required mainly for the process of cellular respiration, a process which plants use to generate energy that is required by the cells to carry out basic functions such as growth and movement. Without these basic functions animals can not survive. Therefore; when animals are deprived of oxygen, they may utilize nutrients through anaerobic (without oxygen) respiration, after which they will eventually die.
Answer: 9x10-3ms-1 -- A
Explanation:
Given wavelength λ = 505nm
1nm= 10^9m
505nm = 5.05 x10 ^-7m
and speed of light, c is 3.8 x 10^ 8
frequency = ?
Using frequency = speed of light / wavelength
f = c/λ
Frequency , f= 3.8 x10^8m/s/ 5.05 x10 ^-7m
=5.94 x 10 ^14 s⁻1
Also Energy = hv
where h =Planck constant = 6.626 x10 ^ -34 J.s
v= frequency =5.94 x 10 ^14 s⁻1
Energy = 6.636 x10 ^ -34 J.s x5.94 x 10 ^14 s⁻1
= 3.935 x 10 ^-19J
Given
9.5×10 −12 g as the mass of the bacterium,
changing to kg
1000g= 1kg
9.5×10 −12 g = 9.5×10 −15kg
to find the velocity
Energy = 1/2mv² = E=1/2mv²
v=
=
v =0.009099= 9x10-3ms-1
<u>Answer</u>:
Chromosomes control cell processes by coding for the production of all a cell's proteins.
<u>Explanation</u>:
Chromosomes are the complex structures that are made up of DNA and attached histone proteins that stabilize the nucleosome structure. DNA is made up of a sequence of polynucleotides that encodes the genetic information of that organism.
The combination of three nucleotides known as triplet codon provides a unique code for a particular amino acid. After transcription of the DNA sequence into mRNA, it is sent to the cytoplasm of the cell to be translated into a particular protein. There are many proteins in a cell each having different sequence and hence they differ in their folding which give them a particular structure to perform a particular activity. Hence different DNA sequences encode the information for different sequences of amino acid in a polypeptide chain which makes the protein.
Definitely #2 is the answer
Answer
The above statement is true.
A spit is formed through wave deposition
Explanation:
-A spit is an extended stretch of beach material that projects out to sea and is joined to the mainland at one end. Spits are also created by deposition.
-Spits are formed where the prevailing wind blows at an angle to the coastline, resulting in longshore drift. An example of a spit is Spurn Head, found along the Holderness coast in Humbersideore Brainlym
