How does a change in an organism's DNA affect the proteins that are made in that
organism's cells?
Answer:
By changing a gene's instructions for making a protein, a mutation can cause the protein to malfunction or to be missing entirely. When a mutation alters a protein that plays a critical role in the body, it can disrupt normal development or cause a medical condition.
How do changes in one area of the world affect other areas of the world based upon the cycling of water?

The deer in your Plains exhibit are suffering from sickle cell anemia. You have a deer that
was donated to the zoo to try and increase the deer population and the genetic diversity of
the herd. This deer does not have sickle cell anemia. How would you find out if this deer is
a carrier of the sickle trait? Show your work on the Punnett squares below and explain the
process you would take to determine the genotype of this deer. (4 Points)
Answer:
To find out if the donated deer is a carrier of sickle cell anemia you would need to breed the donated deer with one of your other deer. If the deer is a carrier, 50% of the offspring will have the disease and 50% will not. If the deer is not a carrier, 100% of the offspring will not have the disease.
Punnet squares are in the file attached
Notes:
- Blue is one deer with sickle cell anemia, red is the donated deer

(psychology)
Answer:
According to Quiz let, D
Explanation:
All the following are considered higher-order traits in Hans Eysenck's hierarchy of traits, except introversion. The correct option is D.
What is introversion?Introversion is the term for the traits of the people who are introverts. The traits of introverts are they concentrate on their own thoughts rather than external ones, and they feel comfortable around few people.
The high-order trait in Eysenck's hierarchy of traits is introversion, which is given in his personality theory.
Thus, the correct option is D, introversion regarding higher-order traits in Hans Eysenck's hierarchy.

Explanation:
Amino Acid?
sequence for the mRNA: AUG-UCA-AUG-UCA-AAA-GAC-CGA-AAA-GAC-CGA-UCA-AUG-AAA-UGA
Answer:
Methionine - Serine - Methionine - Serine - Lysine - Aspartic acid - Arginine - Lysine - Aspartic acid - Lysine - Serine - Methionine - Lysine - STOP.
Explanation:
The task in this question, which is to use the codons in the mRNA sequence to draft out an amino acid sequence depicts the process of TRANSLATION. Translation is the process by which an amino acid sequence is synthesized using the codons in the sequence of a mRNA molecule. The mRNA sequence is as follows:
sequence for the mRNA: AUG-UCA-AUG-UCA-AAA-GAC-CGA-AAA-GAC-CGA-UCA-AUG-AAA-UGA
Using the genetic code (a table showing the proteins encoded by certain codons), the following amino acid sequence is encoded by the mRNA sequence above:
Methionine - Serine - Methionine - Serine - Lysine - Aspartic acid - Arginine - Lysine - Aspartic acid - Lysine - Serine - Methionine - Lysine - STOP.

Which of the following involves the expression of 2 genes at the same time?
O Sex-linked
Incomplete dominance
0 Complete Dominance
o Codominance
Answer:
codominance
Explanation:
means that more than one type of dominant allele for the same Gene is present if black and white fur are dominant,then heterozygous (Aa) offspring would be spotted with black and white.
Codominance refers to the expression of two genes simultaneously. Heter0zyg0us individuals express both phenotypes. So the answer to the question is D. Codominance.
------------------------------------------------------
Sex-linked ⇒ Refers to the gene that is linked to one of the sex chromosomes. In general, genes are linked to the X chromosome. Incomplete dominance ⇒ Refers to the cases in which the heter0zyg0us individual expresses an intermediate phenotype between the dominant and the recessive phenotypes. Neither of the involved alleles completely dominates over the other one.Complete dominance ⇒ When the dominant allele completely masks the recessive allele, we talk about complete dominance. This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant trait. The dominant allele is hiding the expression of the recessive allele. Many genes show complete dominance.CODOMINANCE ⇒ Refers to those cases in which a phenotype expresses two alternative variants inherited from each h0m0zyg0us parent.
When two individuals, who are h0m0zyg0us and different for a trait, are crossed they produce heter0zyg0us individuals.
In codominance, Heter0zyg0te individuals, instead of showing an intermediate phenotype -which is the case of incomplete dominance-, express both alleles.
Their phenotype is an additive expression of their parent's genes. Both alleles are equally expressed.
A typical example of codominance is the case of speckled chicken.
Speckled chickens (BW) are the product of the cross of a black individual (BB) with a white individual (WW). Their progeny will express both genes as speckled feathers.

The textbook presents a very simple, linear scheme of the central dogma of molecular biology (text page 500), but is explicit in noting the simplicity of the original concept and exceptions to it. Which of the following would NOT be reasonable additions or modifications that could be made to this simple linear scheme to account for experimental data?
The textbook presents a very simple, linear scheme of the central dogma of molecular biology (text page 500), but is explicit in noting the simplicity of the original concept and exceptions to it. Which of the following would NOT be reasonable additions or modifications that could be made to this simple linear scheme to account for experimental data?
A. The arrow between DNA and RNA could be reversible.
B. The word "protein" should be made plural (i.e., "proteins").
C. The scheme could be made circular by adding an arrow connecting "protein" to "DNA replication."
D. RNA can be used to generate RNA-based enzymes (ribozymes), so "protein" at the end of the scheme should be changed to "protein/RNA."
Solution :
The central dogma of the molecular biology is described as
DNA → RNA → Protein
Now the arrow between the RNA and the DNA cannot be reversible because practically it does not happen. When the RNA polymerase the enzyme binds to the DNA strand, and the mRNA is made up and whether the protein is for beneficial or not, the mRNA cannot move back to the DNA. Therefore, it cannot be reversible.
For protein name should be made plural
At time, The DNA is transcribed to the mRNA and also one mRNA is transferred to the single protein. If there are more than one protein, then they would be coming from the different mRNAs.
The definition of the central dogma ends at the protein. There is no circular process as the different genes can be transcribed and also translated to the different proteins.

What is involved in the process of artificial selection?
Answer:
Explanation:
Artificial selection is the process by which humans choose individual organisms with certain phenotypic trait values for breeding. If there is additive genetic variance for the selected trait, it will respond to the selection, that is, the trait will evolve.
Answer:
Selective breeding (also called artificial selection) is the process by which humans use animal breeding and plant breeding to selectively develop particular phenotypic traits (characteristics) by choosing which typically animal or plant males and females will sexually reproduce and have offspring together.

Read Changes on Earth and Changes in Life. Explain how changes in Earth’s systems affect the growth of life on Earth. Use evidence from the text to support your answer.
Explanation:
The presence of small amounts of heat-trapping greenhouse gases in the atmosphere warms Earth's surface, resulting in a planet that sustains liquid water and life. Changes in climate conditions can affect the health and function of ecosystems and the survival of entire species.
Answer:
They found four key changes: the unprecedented homogenization of species worldwide through human-instigated species invasions, the growing interaction between the biosphere - the sum of all Earth's ecosystems - and technology; the total domination of one species on land and water; and human impact on evolution.

State two uses of energy in a fly larva.
1:
2:
Answer:
In order to find out the rate of respiration.
Explanation:
The soda lime in the respirometer absorbs carbon dioxide gas which is important in this investigation because we measure the rate of respiration and for measuring that we have to measure the rate of oxygen and carbondioxide so that's why soda lime absorb carbondioxide gas in the respirometer. Growth and movement are the two uses of energy in a fly larva. The energy that is produced in the fly larva is used for the growth of the body and other activities such as mobility etc.
