Hypertensive heart disease is a long-term condition that develops over many years in people with hypertension.

When your high blood pressure (hypertension) is not controlled, it can lead to a variety of health issues, including heart failure and conduction arrhythmias. Hypertensive heart disease is caused by persistently high blood pressure (over 120/80 mmHg). Heart disease risk goes up as people get older and continue to have high blood pressure. People over the age of 65 are more likely to develop heart failure.

Your heart has to work harder to pump blood through your body when you have high blood pressure for an extended period of time.

Photosynthesizing algae produces most of the Earth’s oxygen.

By converting light energy to chemical energy through the process of photosynthesis, carbon dioxide and water are transformed into organic molecules.

Nearly all algae engage in the process, and in fact, much of what is currently known about photosynthesis was first uncovered through research on the green alga Chlorella.

The enzyme ribulose bisphosphate carboxylase binds carbon dioxide to ribulose bisphosphate, a 5-carbon sugar with two linked phosphate groups, during the dark processes.

Genetic variation decreases as a result of inbreeding, genetic drift, restricted gene flow, and small population sizes.

There aren't many variations among individuals in a species with low genetic diversity since there aren't many different gene alleles present. This would imply that there are less chances to adjust to environmental changes. Due to habitat degradation, low genetic diversity is frequently observed.

The difference in DNA between individuals or communities is known as genetic variation. Mutation and genetic recombination are two of the many processes that cause genetic variation. Genetic variety is primarily caused by mutations, although it is also influenced by other processes including genetic drift.

Any material of small granulometry, or up to five millimeters in size, is called sand. From that measure they are called stone. Stones are the result of the breakdown of rocks, just like sand, and in the crushing process it forms crushed stone.

The formation of sand begins with the action of wind, rain, sun, tree roots and microorganisms that wear down the rocks present in various regions of the continent. Over the years, pieces of the stones break loose and, little by little, turn into small grains. This process is called erosion.

Sand is a detrital, mobile, permeable sedimentary rock that, according to the size of its grains, can be classified into coarse, medium and fine sand.

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.

The 1:2:1 genotypic ration dictates the law of are is homozygous dominant, heterozygous dominant and homozygous recessive.

A 1:2:1 genotypic ratio is a ratio of alleles that is found in a monohybrid cross. A monohybrid cross is a type of genetic cross in which only one trait is being studied. In a 1:2:1 ratio, the first number represents the homozygous dominant genotype, the second number represents the heterozygous genotype, and the third number represents the homozygous recessive genotype. This ratio can be found by using the Punnett square method.

This generally represents the genetics, of the first generation of the monohybrid cross made between the pea plant showing dominant and recessive traits. Such that dominant parent was homozygous dominant and recessive parent was homozygous recessive.

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.

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.

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.

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.

Carbon 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.

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.

These impacts include compaction, loss of soil structure, nutrient degradation, and soil salinity. The effects of soil erosion go beyond the loss of fertile land. It has led to increased pollution and sedimentation in streams and rivers, clogging these waterways and causing declines in fish and other species.

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.

All living forms and viruses have proteases. They have repeatedly developed independently.
