Why do disruptive selection pressures tend to favor rapid evolutionary changes?
a. They result in sudden gene frequency changes.
b. They eliminate extreme genetic traits.
c. They select for one variation of a genetic trait.
d. They result in environmental adaptation.
Answer:
The correct answer is a. They result in sudden gene frequency changes.
Explanation:
The evolution of life, its diversity, is reduced to the processes of microevolution or speciation. But not all evolutionary processes in populations end with the formation of a new species. Disruptive selection is a type of natural selection that selects against the average individual in a population. The composition of this type of population would show phenotypes (individuals with groups of traits) of both extremes but with very few individuals in between. Disruptive selection tends to increase intra-population variability and, to this end, favors individuals at both ends of the phenotypic distribution, that is, as a final result there is a break in two different populations, which can lead to speciation.

What energy carriers can enter the electron transport chain in mitochondria to generate ATP?
Answer: The electron transport chain consists of complexes which are the proton pump for the hydrogen ions across the mitochondrial membrane which allows the synthesis of the ATP (energy currency).
Explanation:
The electron transport chain occurs in the mitochondria. ATP synthase present in the inner mitochondrial membrane is a carrier of electron. FADH2 AND NADH two molecules supply high energy electrons from the citric acid cycle from the electron transport chain at complex I (NADH coenzyme Q reductase) and II (succinate dehydrogenase)respectively.

TRUE OR FALSE: The region of DNA where the production of an RNA strand begins is called the INTRON. (if the answer is FALSE, what is the correct answer)
Answer:
True
Explanation:
What are the locations and end products for the processes of transcription and
translation?
Answer: The transcription is the process of production of mRNA molecules from each separate strand of DNA individually and the translation is the production of protein by using the genetic information present in the mRNA.
Explanation:
The process of transcription occurs inside the nucleus of the cell in the eukaryotic cell typically not in prokaryotic cell whereas the translation process occurs in the cytoplasm with the help of ribosome.
mRNA is the product of transcription whereas the polypeptide chain of amino acids is the production of the translation in which further forms the protein.

If a hydrocarbon chain has a carbon to carbon double bond then it is _______________.
Answer:
It is Alkene..........
Answer:
Alkenes
Explanation:
Alkene is a hydrocarbon chain that has a carbon to carbon double. Alkenes are considered 'acyclic' because it has one carbon to carbon double. Since they contain less than a maximum number of hydrogen atoms they are unsaturated.

Growers around the world produce about 3.2 x 107 metric tons of sunflowers each year. One
metric ton is the same as 1.1 short tons. How many short tons of sunflowers do worldwide
growers produce annually?
Answer:
3.5264 x [tex]10^{7}[/tex]
Explanation:
The metric ton is used as a unit of mass. The metric ton in British units can be represented as 2240 pounds or long ton whereas in United state is termed as 1.102 short ton.
In the given question, it has been mentioned that the growers around the world produce about 3.2 x [tex]10^{7}[/tex] a metric ton of sunflower.
So the short ton produced will be
= ( 3.2 x [tex]10^{7}[/tex] ) x 1.102
= 3.5264 x [tex]10^{7}[/tex] short ton.
Thus, 3.5264 x [tex]10^{7}[/tex] is the correct answer.

Philippe did some research about classification for a science report. He learned that until 160 years ago, scientists recognized only two groups of microscopic organisms. How should Philippe explain why scientists decided to classify organisms into more groups?
More types of organisms exist now.
Fewer organisms have gone extinct in recent years.
Scientists invent new organisms that need to be classified.
Scientists continue to learn more about living things.
Answer:
The correct answer would be - Scientists continue to learn more about living things.
Explanation:
In past scientists continues to do various research, findings, studies and experiments regarding diferent type of living organisms and their components and body parts.
These research, studies, and many other aspects of the science helps scientists to conotinue to learn more about living things which helps in provide information that there are different type of organism and should be classified.

2. Oxygen is carried in the blood by the:
Answer:haemoglobin
Explanation:
Inside the air sacs, oxygen moves across paper-thin walls to tiny blood vessels called capillaries and into your blood. A protein called haemoglobin in the red blood cells then carries the oxygen around your body.

meaning of anabolic reaction
Answer:
Anabolism collectively refers to all the processes of chemical reactions that build larger molecules out of smaller molecules or atoms; these processes are also known as anabolic processes or anabolic pathways. Anabolic pathways use energy, while catabolic pathways release energy.

Weigh 10 grams of sugar and then dissolve in 100 mL of water (2
tools).
Answer:
180 gramsExplanation:
The solubility of sugar would be about 180 (a maximum of 180 grams of sugar can dissolve in 100 milliliters of water at room temperature). When a solvent has dissolved the most solute it is called a saturated solutionYou would need a scale to weigh it and a beaker/test tube to hold the water...

Turner syndrome occurs in females who instead of having two X chromosomes have either only one X chromosome or a fragmented X chromosome. Klinefelter syndrome occurs in males who have multiple X chromosomes. Consider the karyotype.
A karyotype indicates that a male has multiple x chromosomes.
Which individual is shown in the karyotype?
male with Turner syndrome
male with Klinefelter syndrome
female with Turner syndrome
female with Klinefelter syndrome
Answer:
male with Klinefelter syndrome
Explanation:
for an individual to be considered male he needs to have at least one Y chromosome
usually an individual with Klinefelter syndrome has two X chromosomes instead of 1 and 1 Y chromosome(XXY) but the karyotype can also be XXXY
Answer:
its B
Explanation:
it belongs to a man with Klinefelter syndrome
