nonsense mutation
Explanation:
The F1 offspring of a cross has been provided for you. It is your job to work backwards in order to determine the genotypes, the genetic makeup, of BOTH parents that produced each cross. More specifically, what parental genotypes would give you these possible genotype combination?
To fill the Punnett Square we must place the alleles from one of the parents horizontally oriented on the top of a 3x3 diagram, and the alleles from the other parent vertically oriented on the left border of the diagram. After that, we must cross each one of the alleles from one parent with the alleles of the other, positioning the result of those crossings (Ee) in the blank space where those alleles meet. Therefore, we must look at the combinations and extract the allele that appears in the same line or in the same column, as follows:
Therefore, the parental genotypes are: EE x ee.
Which observation is true about organisms that carry the same genes?A. They will have the same phenotype, even if there are differences inexpression of the genes.B. They will not have the same phenotype, even if the genes are allexpressed the same way.C. They will have the same phenotype, because they will express thesame genes.D. They will not have the same phenotype if there are differences inexpression of the genes.
The answer would be the letter D. It is because the organism carries the same genotype and will have similar phenotypic characteristics.

What factors can cause an enzyme to become denatured?A. lonization and pHB. Temperature and HumidityC. Humidity and lonizationD. pH and Temperature
The correct option is D. pH and temperature
Enzymes can be denatured in different ways:
-decreases in pH
- increase beyond the optimal temperature
A denatured enzyme refers to an enzyme that has lost its normal three-dimensional, or tertiary, structure that means it is no longer able to function.
True or False: Blood sugar would be lower than normal if liver cells did not have receptors for glucagon.
The answer to the statement " Blood sugar would be lower than normal if liver cells did not have receptors for glucagon " is true.
Why the blood sugar level decreases when liver cells lack receptors for glucagon?It happens that when the liver cells within our body system is short of it deficient of the
glucagon receptor, it usually, frequently and most of the time results in the decreament of the sugar in the blood volume.
However, the hormone known as the glucagon which is manufactured in the pancreas which is designed to stimulate our liver to release the glucose that is previously stored in the body system to the blood stream. Our body system, when it falls on under secretion or over secretion of certain hormones or other substances, it shift the normal body functioning negatively.
So therefore, the absence of glucagon receptor would lowers the blood glucose levels in the blood stream.

Which is NOT a phraseused by Darwin to describeevolution?A. "natural selection"B. "survival of the fittest"C. "struggling for existence"D. "evolution is artificial"
Let's recall what Charles Darwin found:
He stated that natural selection plays a huge role in evolution. He claimed that organisms that had the best traits well-adapted for their specific ecosystem would be able to survive the longest (the most fitness and also known as "survival of the fittest").
Also recall what happens in an ecosystem and food webs as well as the logistical growth equation:
[tex]\frac{dN}{dt}=r_{max}N\bigg(\frac{K-N}{K}\bigg)[/tex]Ecosystems have only so many amounts of resources, or limited resources. Therefore, organisms within the same ecosystem will compete for these resources. These organisms will struggle and fight to survive. They either adapt or they get killed off.
Therefore, the best answer choice that doesn't describe Darwin's statements about evolution is answer choice D.

This passage describes the flower position trait in pea plants:Flowers can grow in different positions on a pea plant's stem. Axial flowers arein the middle of the plant's stem. Terminal flowers are at the tip of the stem.In a group of pea plants, some individuals have axial flowers and others have terminalflowers. In this group, the gene for the flower position trait has two alleles. The allele F is foraxial flowers, and the allele f is for terminal flowers.A certain pea plant from this group has axial flowers. This plant has one allele for axialflowers and one allele for terminal flowers.Based on this information, what is this pea plant's genotype for the flower position gene?axial flowersFfffterminal flowers
Axial flowers are in the middle of the plant's stem.
Terminal flowers are at the tip of the plant's stem.
The alleles that code for the trait "position of the flower" are F: axial flowers, and, f: terminal flowers.
A pea plant has axial flowers (Phenotype of the plant)
You know that it has one allele for axial flowers, F, and one allele for terminal flowers, f.
→ The genotype of the plant is then Ff (heterozygous)

Which of the following statements correctly describes cis-trans isomers?
A) They have variations in arrangement around a double bond.
B) They have an asymmetric carbon that makes them mirror images.
C) They have the same chemical properties.
D) They have different molecular formulas.
E) Their atoms and bonds are arranged in different sequences.
Answer: D
Explanation:
When both double-bond carbons are directly connected to a carbon and a hydrogen, cis-trans can happen. In this instance, a new isomer is produced by switching the substituent on one of the double-bond carbons. Thus, option D is correct.
What are the factor that affect cis-trans isomers?The molecule must restrict rotation. Each doubly bound carbon atom must have two nonidentical groups.
Molecules with the same atomic connectivity are what the cis isomers are known as. On the same side of the double bond, they stand in for comparable page groups.
Cis-trans isomers display a form of stereo isomerism, in which the atoms are arranged differently in three dimensions.
Therefore, On the other hand, trans isomers are made up of molecules with comparable side groups that are situated on the other side of the double bond.

Need help with this question will global warming have catastrophic effects?
Global warming is predicted to produce an increase in extreme temperatures and it is caused mainly by an increase in CO2 levels. The increasing temperatures are likely to cause a modification in air circulation patterns and increase evaporation, among others. These have consequences over climate and produce an increment over frequency and magnitude of extreme climatological events (like hurricanes). Also, global warming leaves no place for adaptation (as it is fast compared to biological adaptation), so many species are likely to go extinct, with important ecological effects. I consider these to be catastrophic effects.

*Explain thoroughly how deforestation affects the fertility of the impacted land?*
Deforestation can have destructive effects on soils. Trees and shrubs shield the ground from the force of raindrops and provide shade that reduces surface soil temperature, which in turn reduces evaporation. Logging and small-scale removal of trees exposes soil to rain splash which loosens and dislodges soil particles, eroding soil and creating a more impermeable bare surface, which increases runoff.
It was found that the majority of soil fertility indices were affected negatively by deforestation and more than half of the organic matter was lost to deforestation, which, in turn, could lead to deterioration in soil quality or land productivity capacity.

Some specifically selected hormones, cholesterol, LDL and iron enter cells via
A) exocytosis
B) endocytosis
C) pinocytosis
D) receptor-mediated endocytosis
Answer:
B) endocytosis
Explanation:
Endocytosis is the process through which things pass through the cell membrane and into the cell.
Endo = internal, within
Cystosis = referring to cells
Some specifically selected hormones, cholesterol, LDL and iron enter cells via Endpcytosis.
Thus, Some plasma-membrane proteins can be efficiently absorbed and concentrated through endocytosis linked to clathrin coating.
This method transports iron-loaded transferrin protein and cholesterol-containing LDL particles linked to these receptors into the cell, and it also internalizes the low-density lipoprotein (LDL) receptor.
By using electron microscopy, it is possible to see the characteristic basket-like structure that the clathrin coat that forms on these structures creates. It is thought that the polymerization of the clathrin coat promotes changes in membrane curvature, surface membrane deformation, and vesicle formation.
Thus, Some specifically selected hormones, cholesterol, LDL and iron enter cells via Endocytosis.
