Answer:

the answer is B. body heat is absorbed by sweat and then transferred to the air, which cools the person

Explanation:

When you sweat, breathe heavily and feel your heart pounding, it doesn't just mean you are having a good workout. These physiological factors are also vital to your body maintaining a state of homeostasis. Homeostasis is defined as a constant, steady environment despite external changes, such as exercise. Exercise affects your body temperature, blood oxygen levels, sugar levels and hydration – all properties necessary for your survival. Your body uses an automatic feedback system to preserve normal temperature and water levels, so you can keep exercising. Eat properly and drink plenty of fluids to help your body maintain homeostasis. so To maintain homeostasis, the blood vessels in your skin dilate to allow more blood flow to the surface of your body where it disperses the heat. ... The evaporation of sweat and breathing out warm air also serve to help cool your body and thereby maintain a steady temperature.

A- there is no chemical reaction when a person is sweating X

B-  sweat DOES evaporate and it is absorbed buy heat and it is the right order

Characteristic 2: The shape of a person's face is a trait that can be inherited.

Explanation:

Inherited traits or phenotypes are those which are naturally and genetically inherited from the dominant parent to the offspring. These are the basic traits with which an individual is born. Most of the inherited characteristics are passed on generation after generations.

To inherit a trait, the phenotypes should be present in the parents naturally by birth and should not be acquired artificially. Few examples of inherited traits include color of the hair, skin or eyes; shape of the face; height of a person; type of hair etc.  

Most of the facial features like shape of the nose or eyes, structure of cheekbones, eye inner corners, area below and above the lips etc  are mostly inherited which also in turn determine the basic shape of the face.

A scar due to an injury happens accidentally and mostly may not be a permanent feature. This feature will not be passed on to the next generation.

Answer:

Only characteristics that are coded for by genes can be inherited. The shape of a person's face is inherited because this characteristic is coded for by genes. Characteristics that are due to environmental factors cannot be inherited. A scar due to an injury cannot be inherited because this characteristic is a result of an environmental factor.

Answer:

Fossil fuels, including coal, oil and natural gas, are currently the world's primary energy source. Formed from organic material over the course of millions of years, fossil fuels have fueled U.S. and global economic development over the past century. Yet fossil fuels are finite resources and they can also irreparably harm the environment. According to the U.S. Energy Information Administration, the burning of fossil fuels was responsible for 76 percent of U.S. greenhouse gas emissions in 2016. These gases contribute to the greenhouse effect and could lead to potentially catastrophic changes in the Earth’s climate. Technologies such as Carbon Capture and Storage (CCS) may help reduce the greenhouse gas emissions generated by fossil fuels, and nuclear energy can be a zero-carbon alternative for electricity generation. But other, more sustainable and less risky solutions exist: energy efficiency and renewable energy.

Pioneer species are the first organisms to appear when succession begins in habitats. They are usually robust species that can survive in harsh conditions and pave the way for other forms of life.

When succession first begins in habitats, the initial organisms that appear are often called pioneer species. Pioneer species are typically hardy organisms, such as lichens or certain types of bacteria and insects, which are capable of surviving in an unoccupied, often harsh environment. They contribute to the creation of initial environmental conditions that eventually allow for the establishment and growth of other, more complex forms of life.

Final answer:

In primary succession, the organisms that first colonize previously uninhabited environments like bare rock are known as pioneer species, with lichens and mosses being classic examples. These species initiate the soil formation process, leading to a more complex ecosystem.

Explanation:

When succession first begins, habitats that were previously devoid of life become colonized by certain hardy organisms. These organisms are known as pioneer species, and they play a critical role in establishing new life in barren environments. A classic example of pioneer species includes lichens and mosses in a process called primary succession.

Pioneer species like lichens consist of a symbiotic relationship between a fungus and an alga or cyanobacteria. These organisms can withstand harsh conditions, such as limited water and nutrients, and are capable of surviving on bare rock. The lichen's ability to photosynthesize and withstand harsh conditions without soil makes it particularly well-suited for this role. As these pioneer species grow, they help to break down solid rock through natural processes, including weathering. This breakdown of rock initiates the formation of soil, which moreover allows for the establishment of other plants and eventually leads to a more diverse ecosystem with a variety of plant and animal life, culminating in a climax community.

Final answer:

Mold and cast fossils originate from the remains of organisms after the skeletal material dissolves. Molds are the hollow impressions left in the rocks, while casts are formed when these molds are filled, creating a three-dimensional representation of the original organism.

Explanation:

Mold and cast fossils are common types of fossilization observed in paleontology. Both processes occur when the original skeletal material dissolves leaving an impression, or cavity, in sedimentary rock. This impression is known as a mold. If the mold later fills with new sediment or mineral deposits, it then becomes a cast. A cast fossil is essentially a three-dimensional replica of the original organism made from the mold.

For example, mollusks such as bivalves and snails often leave behind molds and casts because their shells can dissolve easily. The distinct difference between mold and cast fossils is that a mold represents the negative impression of the organism, while a cast represents a positive, filled-in version of the organism created from the mold. Often, molds can preserve delicate details like the veins in leaves or scales of fish.

Answer:

100% percent of the 4 offspring will have the dominant phenotype

Final answer:

In a Cc x CC genetic cross, all offspring (100%) are predicted to display the dominant phenotype because each offspring from this cross will have at least one dominant 'C' allele.

Explanation:

When predicting the dominant phenotype in a Cc x CC cross, we are looking at the potential genotypes of the offspring. Given that 'C' represents a dominant allele, any offspring with at least one 'C' allele will display the dominant phenotype. In this cross, one parent (Cc) can provide either a 'C' or a 'c' allele, and the other parent (CC) can only provide a 'C' allele. Thus, the possible genotypic combinations for the offspring are: CC (from Cc x CC), Cc (from Cc x CC), CC (from cC x CC), and Cc (from cC x CC). In each case, the offspring has at least one 'C' allele and will show the dominant phenotype.

Therefore, all four offspring (100%) are predicted to display the dominant phenotype.

Predicting offspring genotypes and phenotypes in genetic crosses involves understanding the inheritance patterns of dominant and recessive alleles, as well as applying simple mathematical rules like the product rule and the sum rule to calculate probabilities.

Answer:

coil

Explanation:

DNA is coiled together very tightly, bound together by histone proteins to fit in the small space of the nucleus. See the attached picture for a breakdown of how it coils, from small to large organization.

DNA is compactly organized within the cell nucleus through supercoiling and by wrapping around histone proteins to form nucleosomes, allowing the long strands of DNA to fit into the tiny space while still being accessible for gene expression.

How DNA Fits Inside the Cell Nucleus

When considering the vast length of DNA, which if stretched out, measures approximately two meters for the 46 chromosomes of a human cell, it's remarkable how this fits into a microscopic nucleus. The typical human cell measures about 10 µm, which is clearly much smaller than the length of DNA. The process of supercoiling along with wrapping the DNA around histone proteins enables the DNA to be tightly packaged into structures called nucleosomes. These nucleosomes further fold into a denser structure, making it possible for the lengthy DNA to be neatly packed within the small confines of the cellular nucleus.

This organization allows the cell to maintain access to the genetic information for gene expression, while effectively managing the extensive DNA material.

Oxygen and carbon dioxide are the two nonpolar gases which we exchange during aerobic respiration.

Explanation:

Both oxygen and carbon dioxide are nonpolar and smaller compared to the polar water molecules. These gases pass across the cell membrane through simple diffusion. Gaseous exchange takes place through the thin alveolar and capillary walls in the lungs. Oxygen is taken in and carbon dioxide is released out during this gaseous exchange.

Diffusion of gases is a passive process and hence no energy is actually required. Since the exchange occurs as a passive transport or diffusion across a concentration gradient that is separated by membrane barrier.

Answer:

Vacuole will sooner or later disappear (depends on the salt concentartion outside the cell).

Explanation:

Hypertonic solution (impure water) contributes to higer solute concentration outside the cell (lower solvent concentration) and leads to plasmolysis that allows the movement of solvent from higher concentration to lower cncentration ( water moves outside the cell).

In plant cells, vacuole stores important nutrients and other vital products. Due to high salt concentartion outside the cell, the water will move towards lower solvent concentration (out of the cell) from the cell, the nutrients stored in vacuole will also move primarily to cytosol and then outside the cell which leads cell to wilt. Hence, the vacuole will sooner or later disappear depending on the salt concentrationoutside the cell.

The idea of species is considered real in science because species can interbreed to produce viable offspring and they exhibit distinct morphological traits. These concepts are essential for taxonomy, conservation biology, and understanding evolutionary processes.

Understanding the Reality of Species

Scientists believe in the reality of species because of observed patterns in biology and evidence supporting the theory of evolution. The concept of a species is crucial as it helps in understanding the diversity of life and evolutionary processes. One core reason for recognizing species as real is based on the biological species concept, which states that organisms of the same species can breed and produce viable, fertile offspring, demonstrating reproductive compatibility. Another key reason is the observable morphological traits that differentiate species and allow for classification – the morphological species concept.

In the field of conservation biology, a consistent definition of species is vital for protecting ecosystems and understanding species interactions. Furthermore, the concept of species is foundational for studying evolutionary mechanisms such as mutations, natural selection, and speciation. The ability to define species allows scientists to reconstruct evolutionary pathways and understand biogeography.

Species are fundamental units in biology that serve as a basis for taxonomy and nomenclature. Throughout biology's

history, there have been many species concepts, but the biological, morphological, genetic, and evolutionary concepts are among the most accepted. This plurality reflects the complexity of life and the need for a flexible, yet consistent, understanding of what constitutes a species.

Pedigrees are vital tools for studying inheritance patterns of traits across generations, identifying whether traits are dominant or recessive, and aiding in genetic counseling.

Pedigrees are essential tools that help us understand inheritance patterns within a family over several generations. They are graphical representations much like a family tree and are used to track the inheritance of specific traits, particularly genetic disorders. Pedigree analysis involves using a set of standardized symbols to denote sex, relationships, and phenotypes, facilitating the identification of dominant and recessive traits.

For instance, in a pedigree chart, males are indicated by squares and females by circles. Filled symbols represent individuals with a genetic condition, and by examining who in the pedigree has the disease, geneticists can predict whether the condition is autosomal dominant, autosomal recessive, or sex-linked. This information is invaluable for genetic counseling and for assessing the risk of diseases being passed to future generations.

By studying pedigrees, geneticists can make informed predictions about whether a trait will appear in an individual's offspring based on the previous appearance of the trait in ancestors. This is crucial for families with histories of genetic illnesses like Huntington's disease or cystic fibrosis. Pedigrees not only help with understanding disease inheritance but also assist in the calculation of the probability of an offspring inheriting a particular trait or disorder.

Final answer:

Artificial selection can lead to reduced genetic diversity, increased disease susceptibility, and potential health issues in the organisms being bred due to the focus on specific, sometimes purely aesthetic, traits.

Explanation:

One problem with artificial selection is that it may reduce genetic diversity among the organisms being bred. The process involves selecting individuals with desirable traits for reproduction, often leading to a population that shares very similar genes. As a result, the reduced variability in the gene pool can lead to an increased susceptibility to diseases, as the organisms lack diverse defenses. Furthermore, in focusing on particular traits, other beneficial genetic traits may be inadvertently lost or negative traits may be amplified unintentionally. For example, some dog breeds have been artificially selected for specific aesthetic traits, which has led to health issues related to those physical characteristics, such as respiratory issues in brachycephalic breeds like bulldogs and pugs.

Final answer:

Artificial selection can create organisms with traits that are too specialized for human use, leading to a dependency on humans and decreased ability to survive in the wild.

Explanation:

One problem with artificial selection is that it can lead to animals and plants that are highly specialized for human use but lack the ability to survive without human intervention. Domesticated species often possess traits that are exaggerated or deleterious in their natural environments. For instance, certain breeds of dogs or varieties of plants may be so specialized due to artificial selection that, should they find themselves in the wild, they would likely struggle to survive against predation, disease, or environmental stresses. This dependence on humans can be a significant drawback because it makes artificially selected organisms vulnerable outside of their cultivated habitats.
