:) How does reducing heart rate during a dive enable animals to stay underwater longer?

The classes of chordata which are warm-blooded are birds and mammals.

Explanation:

Warm-blooded animals are those which can maintain their body temperature at a constant.  

These classes of chordates balance their internal body temperature with that of the outer environment. When the outer environment is cold, they increase their internal temperature by producing more heat; and when it is hot outside they reduce their internal temperature by cooling themselves.  

The food consumed by a warm-blooded animal fuels to maintain a constant body temperature and hence they require more food.  

Warm blooded animals cool themselves with the help of sweat glands.  

The skin and other parts like fur in birds help to keep the animals warm during winter. Birds also shed their fur in hot season to keep them light. Birds migrate to warm regions during winter.

These animals have high stamina and energy to survive environmental changes. They maintain their temperature through endothermy, homeothermy or tachymetabolism.

Whale living in water is the fish which is also warm blooded because it is a mammal.

ATP used as an active energy source over glucose because it is more efficient.

Explanation:

The Adenosine triphosphate molecule or its more usable short form ATP is a prominent and perhaps primary energy source in the cellular system and the function of extracellular energy transfer.

ATP is efficient in transporting and storing chemical energy within cells.

This is rather different considering that the glucose molecule actually possesses more energy . ATP has less energy but can use it more judiciously ad effectively than the other. It is thus more usable and is also used in the treatment of Nucleic acids.

Rigel, with a high temperature and luminosity, would be placed at the top-left position on the HR Diagram, corresponding to a hot, bright supergiant star.

The HR Diagram, known as the Hertzsprung-Russell diagram, is a graphical tool that astronomers use to classify stars according to their luminosity, spectral type, color, temperature, and evolutionary stage. Given Rigel's temperature of 12,300 degrees Celsius and luminosity of 55,000 times that of the Sun, Rigel can be placed at the top-left position on the HR Diagram. This is because the top of the diagram represents stars with higher luminosities, and the left side represents stars with higher temperatures.

Rigel, therefore, corresponds to a letter representing high temperature and high luminosity, typically one of the earlier letters such as "A" or "B" on most HR Diagrams, indicating that it is a hot, bright supergiant star.

Meiosis II is reduction  division which produces four nuclei in 4 haploid cells for a total of four nuclei.

Explanation:

Meiosis 2 is the second phase of meiosis in which each diploid cell gives 2 haploid cells forming four haploid cells. It takes place in eukaryotic cells in gametes or germ cells. Sister chromatids separate in meiosis 2.

It comprises following stages:

prophase II : nuclear membrane breaks down as chromosome condense. spindle fibres get formed and microtubules prepare to grip chromosome.

metaphase II : The chromosomes are lined at metaphase plate.

Anaphase II: the sisters chromatids gets pull apart.

telophase II : nuclear memebrane is formed around each pair of chromosomes, decondensation of chromosomes occur and cytokinesis follow making four haploid cells.

Meiosis II is the division that produces haploid nuclei in four cells, resulting in a total of four haploid nuclei.

Meiosis II is the second stage of meiotic cell division, following meiosis I. It is a type of cell division that occurs in sexually reproducing organisms to produce haploid gametes. During meiosis II, the primary objective is to further reduce the chromosome number in each cell, ensuring that the resulting gametes are haploid.

Meiosis II involves the separation of sister chromatids, which were produced during meiosis I. This separation process occurs in four daughter cells, each with half the number of chromosomes as the original parent cell. Therefore, meiosis II is a division that produces haploid nuclei in haploid cells. In total, meiosis II produces four nuclei, each contained within a separate daughter cell.

The process of meiosis II is crucial for maintaining the haploid state of gametes, ensuring that when fertilization occurs, the resulting zygote has the correct diploid chromosome number. Additionally, meiosis II contributes to genetic diversity through processes such as independent assortment and crossing over during meiosis I, leading to unique combinations of genetic material in each gamete.

Answer:  Ecologists mesure biomass in grams of organic matter per unit area.

Wild Bedbugs become insecticide resistant because of the mutations and natural selections.

As the huge amount of pesticides and insecticides are sprayed in the rooms for cleaning, the pests and insects like bedbugs dies in huge portions because of the toxin. But some of the bedbugs remain alive as they have mutations that help them to detoxify the toxins given, or bypass the metabolic processes so that the toxins don't hamper them much.

Now as the population becomes very small(bottle neck effect), the nature selects these organisms over the other to propagate more sufficiently and enormously. As the nutrients and supplies are also available, so the bedbugs don't suffer any lack of nutrition which can be a determining factor of their population.

Thus the wild bedbugs become resistant to insecticides while the experimental one remain succeptible to insecticides.

Answer:

Resistance to insecticides is a trait that passes from parent to offspring in the gene pool. In the scientist’s bed bug population, resistance to insecticides isn’t an important trait to increase their chances for survival. So, the bugs’ genes won’t select for this trait. However, in the natural environment, bed bugs with insecticide resistance are more likely to survive, so selection occurs.  

Final answer:

Mendel reached two conclusions about inherited traits: the Law of Segregation and the Law of Independent Assortment.

Explanation:

Mendel reached two conclusions about inherited traits after completing his experiments with pea plants:

Law of Segregation: Mendel observed that the two alleles for each trait separate during the formation of sex cells. This means that each parent contributes one allele for a specific trait to their offspring. For example, when a plant with yellow smooth peas is crossed with a plant with green wrinkled peas, the resulting offspring will inherit one allele for pea color (either yellow or green) and one allele for pea texture (either smooth or wrinkled).

Law of Independent Assortment: Mendel found that the inheritance of one trait is not influenced by the inheritance of another trait. For instance, the alleles that code for different traits, such as pea color and pea shape, sort independently during meiosis. This means that the expression of one trait does not affect the expression of another trait in the offspring.

Answer:

The answer to your question is D, Sugar

Final answer:

The correct option for a carbohydrate that stores energy is D. sugar, which includes glycogen, a polysaccharide used by animals for short-term energy storage.

Explanation:

Carbohydrates are fundamental biological molecules that serve various roles, including energy storage. An essential simple sugar, glucose, shows the compact and immediate energy supply carbohydrates can provide. However, for longer-term storage, animals use a polysaccharide known as glycogen. Glycogen is made from hundreds or thousands of glucose units and is particularly abundant in liver and muscle cells. It serves as an energy reserve and is utilized when the body is fasting to maintain metabolic balance. Unlike fats or proteins, glycogen can supply the energy quickly due to its more accessible structure for enzymatic breakdown. This is why glycogen is a primary form of energy storage in animals.

The correct option from the list provided that is an example of a carbohydrate that stores energy is D. sugar. The sugars, specifically in the form of glycogen, are utilized by our bodies for short-term energy storage. This is in contrast to fats, which serve as long-term energy reserves but are not carbohydrates.

Final answer:

Eye color, such as Danielle's blue eyes, is determined by complex hereditary patterns in biology; it results from the interactions of multiple genes contributing to the phenotype of an individual's eye color.

Explanation:

The term that describes Danielle's eye color, which is blue, pertains to the concept of genetics in biology. Eye color is determined by multiple genes and is a result of complex inheritance patterns, often referred to as non-Mendelian inheritance. These patterns involve various genes contributing to the phenotype of an individual's eye color, making it possible for a range of eye colors including green, blue, brown, black, hazel, violet, or grey. The pigment responsible for blue eye color is due to the lack of melanin in the stroma of the iris, which causes light to scatter in a way that makes the eyes appear blue.

Physical weathering, also known as mechanical weather, is the process of rocks and minerals on Earth's surface breaking down or dissolving as a result of water, ice, salt, plants, animals or changes in temperature. Physical weathering does not change the chemical composition of the rock, just cracks and crumbles it into smaller pieces. After a rock has weathered, erosion occurs, transporting bits and pieces away. Finally a deposition process deposits the rock particles in a new place.

Physical weathering by plants, wind, and ice rock fragments to their new location. Water flowing quickly Ice wedges numerous rocks break as a result of ice plant roots can spread.

Physical weathering, often referred to as mechanical weathering, is the breakdown or dissolution of rocks and minerals on Earth's surface as a result of water, ice, salt, plants, animals, or temperature changes.

The granite just splits and crumbles into smaller pieces as a result of physical weathering, which does not alter the chemical makeup of the rock.

Answer:

Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.

Final answer:

Cellular respiration is the process by which plants and animals convert glucose into ATP, with glycolysis, the citric acid cycle, and oxidative phosphorylation being the main stages.

Explanation:

The cellular process that allows plants and animals to convert glucose into ATP energy is known as cellular respiration. This metabolic process is crucial for life, as ATP acts as the energy currency for cells, powering various cellular activities. Cellular respiration begins with glycolysis in the cell's cytoplasm, where glucose is partially broken down. Then, inside the mitochondria, the process continues through the citric acid cycle and concludes with oxidative phosphorylation, producing ATP.

Both plants and animals perform cellular respiration, although plants also create glucose through photosynthesis using sunlight. The oxygen used in cellular respiration yields water and carbon dioxide as byproducts, which are, in turn, utilized by plants to perform photosynthesis, thus creating a cycle of energy transformation within the ecosystem.

Heterozygous Red- Rr

Homozygous Red-- RR

Homozygous white-- rr

Monohybrid cross- Rr

Recessive allele- homozygous white i.e rr

Explanation:

Heterozygous have 2 different alleles of a gene as both Red and white alleles are present in the example Rr.

Homozygous: If the 2 alleles at a locus is same then they are homozygous, it can be dominant as RR or recessive as rr.

Recessive gene are the ones that can be masked by the dominant genes as red is dominant on white.

Monohybrid cross is the result of cross between the individual having either homologous dominant or recessive genes or genotype. The result is generally masking the recessive allele resulting in dominant phenotypic trait but the genotype changes.

From the example given in question:

A cross between dominant red as RR

and a cross between recessive white as rr

The punnet square shows:

  r     r

R Rr  Rr

R Rr   Rr

it can be seen that all progeny are red but genotype changed to heterozygous red as Rr

Because in Mount St. Helen some seeds and species were left and some turned back on their time causing the ecosystem of the area develop again.

Final answer:

Invasive species can dramatically reduce biodiversity by outcompeting native species, altering habitats, spreading diseases, and causing substantial ecological and economic damage.

Explanation:

The impact of invasive species on the biodiversity of an ecosystem is significant and multifaceted. Invasive species can outcompete native species for resources, significantly alter the structure and dynamics of environments, change nutrient cycling, and convert native habitats into ones dominated by the invader. For instance, invasive plants may modify fire regimes, which in turn affects nutrient cycling and ecosystem composition.

In some instances, these species hybridize with native ones, leading to genetic changes and even extinction of native species. The presence of invasive species often leads to reduced native biodiversity and can carry parasites and diseases that threaten native species, agriculture, and even human health. Additionally, the economic costs of managing invasive species, such as losses in agriculture, can be staggering.
