What condition are needed do an accurate radiometric date to be obtained form a mineral ample?
The necessary condition is that the mineral must remain closed since its formation.
Radiometric dating, radioactive dating, or radioisotope dating is used to date rocks and carbon with trace radioactive impurities.
Heat, pressure, and temperature do not affect isotope decay. Radiometric dating is reliable. This method dates igneous and metamorphic rocks that sedimentary stratigraphic correlation cannot. 300 natural isotopes exist.
The parent's half-life must be known and long enough for it to be present in significant amounts at the time of measurement for accurate radiometric dating. Thus, mineral samples require these conditions for radiometric dating.

. An organism that has two different alleles of a given gene has a(n) _____ genotype. aneuploid dizygous heteromorphic heterozygous homozygous
An organism that has two different alleles of a given gene has a(n) heterozygous genotype. aneuploid dizygous heteromorphic heterozygous homozygous
Heterozygous genotypes are characterized by two different alleles of a particular gene. These alleles can be inherited from different parents or from the same parent, and this type of genotype is also known as a dizygous genotype.
An example of this is eye color; if an individual has one allele for blue eyes and one allele for brown eyes, they would have a heterozygous genotype. This type of genotype is important for producing genetic diversity, allowing for adaptations that can be beneficial to a species. It is also important to note that having a heterozygous genotype does not guarantee that the individual will express the traits of both alleles; rather, the individual will usually express the trait of the dominant allele.

Do whales need oxygen to survive?
Yes, whales need oxygen to survive. Like us, whales are mammals that breathe air into their lungs. Because they lack gills, they can't breathe underwater like a fish can.
A blowhole, or nostril, on top of their heads, allows them to breathe. While swimming or resting beneath the water, this enables them to take deep breaths by only exposing the tops of their heads to the air. The strong muscles that surround the blowhole close it tightly after each breath to prevent water from entering the lungs of the whale or dolphin.
Dolphins only have one blowhole, whereas large whales, with the exception of the sperm whale, have two blowholes.

What happens when CO2 increases in the ocean?
More carbon dioxide is evaporating into the ocean as a result of human-driven increases in atmospheric carbon dioxide concentrations. Currently, the ocean has an average pH of 8.1, which is basic (or alkaline), but when more CO2 is absorbed, the pH drops and the ocean becoming more acidic.
Ocean acidificationCarbon dioxide dissolves in seawater as it reaches the ocean. It first creates carbonic acid. The carbonic acid then "dissociates," or separates, into bicarbonate ions and hydrogen ions. Ocean acidification is caused by an increase in hydrogen ion concentration and a decrease in carbonate ions as a result of increasing CO2 absorption.
Carbonate ions are necessary for the growth of the shells and thriving of clams, mussels, crabs, corals, and other marine life.

A high relative humidity and sunshine hinder heat loss from the body by their adverse effects on the body, respectively, as:
The correct option (C) decreased evaporation and increased radiation.
Why does relative humidity climb the most just before dawn?
The ability of the air to hold water vapor increases with temperature. As a result, relative humidity rises as the temperature rises and reduces as it approaches the dew point. Around daybreak, when the nighttime low temperature is generally quite close to the dew point, the relative humidity is typically at its peak.
How does a high relative humidity affect things?
The "Heat Index" is the name given to this combined impact. The heat index increases with increasing air temperature and/or relative humidity, making the outside air seem hotter to our bodies.

What happens when protease is added to protein?
When protease is added, proteins breakes into smaller polypeptides or single amino acids, and forms new protein products.
A protease is an enzyme that catalyzes (increases reaction rate or "speeds up") proteolysis, breaking down proteins into smaller polypeptides or single amino acids and promoting the creation of new protein products. It is also known as a peptidase, proteinase, or proteolytic enzyme.
They achieve this by using hydrolysis, a mechanism in which water breaks bonds, to cleave the peptide bonds found in proteins. Protein digestion after ingestion, protein catabolism (the breakdown of aged proteins),[3][4] and cell signaling are only a few of the biological processes that proteases are involved in.

Describe the similarities and differences between alcoholic fermentation carried out by yeast to make alcoholic beverages and lactate-acid fermentation carried out within the human body. Source StylesFormatFontSize
The main difference between alcoholic fermentation and lactic acid fermentation is that of their end-products.
The primary distinction between lactic acid and alcoholic fermentation is that the latter results in the production of ethyl alcohol and carbon dioxide while the former yields lactic acid molecules from pyruvate.
Differences between the two processes include he following:
Pyruvate and lactate are produced directly after fermentation of lactic acid. Pyruvate is converted to ethanol by the two-step process of alcohol fermentation.End-products: Lactase and energy in lactic acid fermentation, while C02, alcohol, and energy in alcoholic fermentation are the end products. The enzymes involved in the fermentation processes of lactic acid are lactate dehydrogenase and pyruvate decarboxylase. Pyruvate decarboxylase and alcohol dehydrogenase are the two enzymes required for alcoholic fermentation.Similarities between the two processes include the following:
The two pathways convert ATPs from the breakdown of glucose.The two processes' major objective is to recycle NAD+ in order to keep glycolysis going and allow for the NAD+ to be reduced back to NADH in the process.Both processes release heat energy and are exergonic.Each produces 4 ATPs during glycolysis, the same amount as the other.To know more about fermentation, refer to the following link:

In a certain plant, yellow leaves are dominant (Y) and red leaves are
recessive (y). A plant with genotype Yy and a plant with yy are crossed. If they have four offspring, how many would you predict would have red leaves? (Hint: Draw a Punnett square to help you determine the answer.)
A. 4
B. 3
C. 2.
D. 1
Answer: C
Explanation: When a plant with genotype yy and Yy are crossed there will be two yellow offsprings with genotype Yy(where yellow is dominating) and another two with yy(where leaves are completely red)
According to the information provided, yellow leaves (Y) are a dominant characteristic over red leaves (Y), which means that if the allele for yellow is paired with allele for red leaves as can be seen in Punnett square, it will hide the expression of red leaves. So, the correct option is D.
What is Punnett Square?The genotypes of a specific crossing or breeding experiment are predicted using the Punnett square, a square diagram. Biologists use the figure to calculate the likelihood that a child will have a specific genotype.
The information given indicates that yellow leaves (Y) have a dominant trait above red leaves (Y), that implies that if the alleles for yellow and red leaves are linked together as shown in Punnett square, this will conceal the manifestation of red leaves.
For red leaves, the genotype is yy, while the two potential genotypes for yellow leaves are YY and Yy. Parents have the genotypes Yy and Yy. When they are crossed, one of every four offspring that results will have red leaves.
Therefore, the correct option is D.
