Review the following characteristics for a population in a country:
Both birth and death rates are at extremely high levels
Population is increasing
Which stage of demographic transition does this describe?
a. Stage 1
b. Stage 2
c. Stage 3
d. Stage 4
Answer:
A) Stage 1
Explanation:
Demographic transition has to do with the changing pattern of factors that impact population such as birth rates, death rates as the population moves from regime to regime. The transition is in four stages:
Stage 1: which is characterized by high high birth and death rates. also known as pre-transition stage.Stage 2: Characterized by falling death rate but continued high death rate. Also known as early transition stage.Stage 3: characterized by a decline in birth rate and deceleration of population growth. It is also known as late transition period.Stage 4: Characterized by low birth and death rate. Negligible population growth. Also known as post-transitional period.Which of the following is NOT a way that industry can cause pollution?
A. putting smoke into the air
B. using chemicals that can wind up in the water supply
C. burning substances that put chemicals into the air
D. using detergents that put phosphates into the water
Answer:
A. putting smoke into air
Explanation:
Can't be B. because they are harming the water from dangerous chemicals. Not C. because they are harming the atmosphere from dangerous chemicals. Not D. because phospate is used in fertilisers and if that gets in water it will cause algae bloom a sudden growth in algae which will block light from coming in the river or lake and so hydrophytes(aquatic plants) will die and fish will not get any oxygen so will also die. The algae bloom creates toxic stuff because of competition and will make the river of lake dangerous to be in. We are only left with A. so that is the answer.
Answer:
Its D

Using detergents that put phosphates into water

4. Which is an example of artificial selection?
-There are 4 different species of Hyena
-Red fox and Fennec Fox
-Fancy Pigeon breeds raised by Mike Tyson
-A Peacock and a Peahen
Answer: Fancy Pigeon breeds raised by Mike Tyson
Explanation:
Having 4 species of hyena and having a Red fox and Fennec fox are not artificial selection; they are natural species differences. Having a peacock and a peahen is an example of dimorphism. Fancy pigeon breeds are artificially selected for their most desirable characteristics - humans interfere with natural selection.
Answer:
Fancy Pigeon Breeds raised by Mike Tyson
Explanation:
This is because the selection is being performed by a human for artificial and cosmetic reasons and the pigeons are being bred for their "fanciness." Natural selection happens because an animal needs to adapt for survival reasons, whereas this artificial selection isn't happening "naturally" for survival reasons, only for looks, etc.

If dna of a particular species was analyzed and it was found that it contains 27 percent a, what would be the percentage of c?.
DNA of that particular species contains 23 % of C
How can we calculate the percentage of DNA?Adenosine (A) is complimentary with Thymine (T), that means that there is 27% of A + 27 % of T = 54%
To calculate the percentage of Cytosine (C) we need to know that C and Guanine (G) are also complementary. That means that the remaining 46% is half C and half G.
Therefore, the percentage of C is 23%.

what happens during translation?
a) each strand of DNA is used as a template to produce a complementary strand of DNA
b) each strand of DNA is used as a template to produce a strand of DNA with the same sequence as bases
c) each strand of DNA is used as a template to produce a complementary strand of mRNA
d) codons coded in the mRNA are used to produce a string of amino acids
During translation, codons coded in the mRNA are used to produce a string of amino acids. The correct answer is D.
Translation is the process in which the genetic information encoded in the mRNA molecule is used to synthesize a protein. It takes place in the ribosomes, where transfer RNA (tRNA) molecules carrying specific amino acids bind to the corresponding codons on the mRNA. The sequence of codons on the mRNA determines the sequence of amino acids in the resulting protein.
The process begins with the initiation stage, where the small ribosomal subunit binds to the mRNA and the initiator tRNA recognizes the start codon. Then, the large ribosomal subunit joins the complex, and the elongation stage begins.
During elongation, the ribosome moves along the mRNA molecule, reading each codon and bringing in the appropriate tRNA molecule with its attached amino acid.
The ribosome catalyzes the formation of peptide bonds between adjacent amino acids, forming a growing polypeptide chain. This process continues until a stop codon is reached, signaling the termination stage and the release of the completed protein.
In summary, translation involves the decoding of the mRNA sequence by ribosomes, using tRNA molecules and their associated amino acids to assemble a polypeptide chain according to the instructions carried by the codons on the mRNA. Therefore, the correct answer is D.

how do tears form and why do they have a salty taste?
Answer:
They are produced by the lacrimal glands above your eyes. They drain into tiny holes in the corners of your upper and lower eyelids before traveling through small channels, and down your tear ducts to your nose. Our tears taste salty because of electrolytes.
