Most of the GMO crops grown today were developed to help farmers prevent crop loss. The three most common traits found in GMO crops are: (1) resistance to insect damage; (2) tolerance to herbicides; and (3) resistance to plant viruses. Let's consider #2, tolerance to herbicides: farmers using herbicide-tolerant crops do not need to till the soil, which they normally do to get rid of weeds. Which of these is NOT a positive environmental and economic impacts of this GMO trait?
A) Reduced soil tillage results in less soil erosion.
B) No-till planting results in lower fuel and labor costs.
C) No-till planting results in higher crop yields per acre.
D) No-till farming results in increased organic matter and cycling of nutrients in the soil.
Answer:
B. No-till planting results in higher crops yields per acre.

Plants are not an example of an abiotic factor
Explanation:
Answer:
plants are living/biotic so this means it isn't abiotic. (abiotic means nonliving)
Explanation:
In mice, the allele for black coat color (B) is dominant over the brown allele (b). Two heterozygous mice are mated, and produce the following offspring:
20 black
4 brown
What is the EXPECTED FREQUENCY of black and brown mice in the offspring from this cross?
a. 5 black: 1 brown
b. 3 black: 1 brown
c. 2 black: 1 brown
d. 1 black: 3 brown
Answer:
a. 5 black: 1 brown
Explanation:
This question involves a gene coding for coat color in mice. The allele for black coat color (B) is dominant over the brown allele (b). This means a mouse that is heterozygous for the Gene will have a black coat color.
According to this question, two heterozygous mice are mated i.e. Bb × Bb to produce the following offspring: 20 black mice and 4 brown mice.
Based on this result, the EXPECTED FREQUENCY of black and brown mice in the offsprings can be calculated;
20 black ÷ 4 = 5
4 brown ÷ 4 = 1
The expected frequency of black to brown is 5:1.

If you could genetically engineer a more efficient system of carbohydrate digestion for the ruminant, what would you try to make the new system accomplish
Answer:
Make sure the complex carbohydrate are simpler to enhance better and easier digestion
Explanation:
If I could genetically engineer a more efficient system of carbohydrate digestion for the ruminant, I would you try to make the new system accomplish a a simpler form of carbohydrate.
This will enhance a better and easier digestion and absorption as a result of the challenges ruminant animals face as a result of the complex carbohydrate they take in which makes them regurgitate to digest it properly.
Which of the following correctly describes the role of biomolecules in energy storage ?
Answer:
Biomolecules are crucial to the storage of energy energy in the body.
Biomolecules conserve energy using covalent chemical bonds.
Explanation
A covalent bond in chemistry refers to a chemical bond that is formed when two atoms share a pair each of electrons.
So some of these molecules which have high energy (such as glycogen and triglycerides) are able to keep or store such energy in the form of covalent chemical bonds. Examples of energy-rich biomolecules are:
glycogen and triglyceridesCells synthesize such molecules and store them for later release of the energy.
Cheers
Answer: B. Carbohydrates are used for short-term energy storage, and lipids are used for long-term energy storage.
Explanation:
Humans and animals use carbohydrates for short-term energy storage and are stored as glycogen which can be broken down into glucose when energy is needed.
Lipids are used for long-term energy and are stored as fats in the body. These fats can be broken into fatty acids when the body needs energy.

How many sex chromosomes does the normal human female inherit from her mother?
A. 1.2
B. 2.46
C. 3.22
D. 4.1
E 5.23
Answer:
A. 1.2
Explanation:
Normally, a human body cell contains 46 chromosomes - 23 inherited from the father and the same number from the mother.
Most of the human DNA, or human genes, are located in the chromosomes.
Each metaphase chromosome consists of:
two sister chromatids containing one DNA molecule each, and since they are formed by replication, these molecules are completely identical in gene content; that is why chromatids are called sister chromatids; two centromeres, one on each chromatid.

Which statement is accurate about dominant alleles? (1 point)
O They are expressed whenever present.
O They are indicated by lowercase letters.
O They result in the trait of shortness in pea plants.
O They are expressed only when a recessive allele is not present.
Answer: I believe it would be A "They are expressed whenever present."
Explanation: Dominant alleles always show up, in the F1 generation the recessive allele are masked.
The statement is accurate about dominant alleles is they are expressed whenever present. Hence option a is correct.
What are dominant alleles?Dominant alleles are defined as a gene variant that, despite the presence of other alleles, will result in a certain phenotype. Dominance is a phenomena in genetics when one version of a gene on one copy of a chromosome obscures or overrides another version of the same gene on the other copy of the chromosome.
Completely dominant alleles will always be expressed in the phenotypic of the cell. The dominant allele is therefore always expressed, but because penetrance might vary, it is sometimes not as clearly represented in the phenotypic of the cell as you would anticipate from a dominant allele.
Thus, the statement is accurate about dominant alleles is they are expressed whenever present. Hence option a is correct.

Chromosome structure can be microscopically observed best during.
a. telophase b. anaphase c. prophase d. metaphase 1
Answer: chromatin condenses into chromosomes and can be best observed in prophase.
Explanation: chromosomes can’t be visualised by a light microscope except during cell division (mitosis or meiosis). The individual chromosomes become visible as the chromatin is wound tightly and are most clealry seen in late prophase.
