Mary is in the lab studying the bones shown in the picture below. Tom says she is doing comparative anatomy because she is doing what?
A- looking at fossils of organisms that have gone extinct
B- looking at embryos of unrelated living organisms
C- looking at similarities and differences in the structures of different species
D- looking at sexual dimorphism of sexually reproducing species​

All of the pairs are equally different genetically ( D )

Genetical similarity is when the DNA composition of a specie shares a high percentage of similarity with another population of species. and all the listed species ( in pairs ) have little or no Genetic similarity due to the absence of similar DNA composition between them.

Humans share a 98% DNA composition similarity with Chimpanzees and a 99.9% DNA composition is seen between fellow humans, therefore humans and Chimpanzees can be said to be similar genetically.

Hence we can conclude that All of the pairs listed in the options are equally different genetically

Humans are susceptible to a wide range of diseases brought on by germs. Humans frequently contract bacterial illnesses such tetanus, TB, pneumonia, typhoid, and others.

Thus, Pathogenic bacteria are those that infect people and cause various diseases. The body's defense system's ability to produce innate immunity allows us to support the growth of numerous microorganisms.

Disease-causing bacteria can enter body fluids and tissues by outpacing the body's own defense mechanisms. Bacteria can either directly harm cells, release toxins, influence how cells function, or trigger an immunological reaction that harms the cells.

Diseases brought on by bacteria are called bacterial diseases. The human body contains a variety of microbes. Many of these are referred to be "good bacteria" because they don't lead to any diseases.

Thus, Humans are susceptible to a wide range of diseases brought on by germs. Humans frequently contract bacterial illnesses such tetanus, TB, pneumonia, typhoid, and others.

The Hadean is considered the first division of the Precambrian, it starts with earth formation and ends with the Archean, lasting 567 million years. This eon is characterized by intense volcano activity, and a quite turbulent environment, nonetheless is in this era that is proposed the first traces of life, going from the first self-replicant molecules and protobionts to the last common ancestor. Taking this into account we can say that the correct answer is option C.

The correct option is D. Biomass is inexpensive and easy to produce but generates air

pollution. Biomass burning might generate carbon dioxide, among other gases, which would counterattack the climate change goals, such as carbon dioxide mitigation.

Answer:

Hyperventilating can only increase a person's oxygen levels in the body by only three to five percent because the body has a natural mechanism to regulate the levels of oxygen and carbon dioxide in the blood. When a person hyperventilates, they exhale more carbon dioxide than they inhale, which leads to a decrease in carbon dioxide in the blood. This decrease in carbon dioxide causes the blood vessels to constrict, which reduces the amount of oxygen that can be delivered to the body's tissues. This is why hyperventilating can only increase a person's oxygen levels in the body by a small amount.

Abiotic variables include things like sunlight, air, precipitation, minerals, and soil, to name a few. These elements significantly affect the persistence and procreation of species within an ecosystem. For instance, autotrophic organisms might not be able to exist without enough sunlight.

What are the four primary abiotic variables?

The nonliving components of the environment, or abiotic influences, frequently have a significant impact on living things. Water, sunlight, oxygen, soil, and temperature are examples of abiotic variables.

What three abiotic elements are present in an ecosystem?

Abiotic factors are non-living components of an ecosystem that influence their surroundings. Examples could be light, water, and temperature in a terrestrial habitat. Abiotic elements in a marine ecosystem would be salinity and ocean currents.

The correct statement is: With channel proteins, molecules or ions flow passively through the protein from high concentration to low concentration.

Neither channel proteins nor carrier proteins themselves flow or move in any direction. They are static structures that are embedded within the cell membrane and act as conduits or gates for the movement of specific molecules or ions across the membrane.

The movement of molecules or ions through these proteins depends on their concentration gradient. Channel proteins allow the passive flow of ions/molecules from high concentration to low concentration, while carrier proteins can facilitate both passive and active transport of molecules across the membrane. In active transport, molecules move from low concentration to high concentration, and this process requires the expenditure of energy (in the form of ATP).

The 4 early concepts of heredity are Blending inheritance, inheritance of acquired characteristics, preformationism, and particulate inheritance.

Here are 4 early concepts of heredity, along with a brief description and classification as either correct or incorrect:

Blending Inheritance: This concept suggests that the traits of offspring are a blend of the traits of their parents. For example, if a tall man and a short woman have a child, the child will be of medium height. This concept is incorrect, as it doesn't explain how traits can reappear in future generations after being absent in previous generations.

Inheritance of Acquired Characteristics: This concept suggests that organisms can pass on traits that they acquire during their lifetime to their offspring. For example, if a giraffe stretches its neck to reach leaves, its offspring will inherit a longer neck. This concept is incorrect, as there is no evidence that acquired traits can be passed on to offspring.

Preformationism: This concept suggests that organisms develop from miniature versions of themselves that already contain all the traits they will have as adults. For example, preformationists believed that humans developed from tiny, fully-formed humans. This concept is incorrect, as it doesn't explain how traits can vary from one generation to the next.

Particulate Inheritance: This concept suggests that traits are determined by discrete units called "particles" that are passed on from parents to offspring. These particles are now known as genes. This concept is correct and forms the basis of modern genetics. It explains how traits can be passed down from one generation to the next and how new variations can arise through the random assortment and recombination of genes.

Answer:

Genomic Instability

Explanation:

Normal cells have normal DNA and a normal number of chromosomes. Cancer cells often have an abnormal number of chromosomes and the DNA becomes increasingly abnormal as it develops a multitude of mutations.In contrast to normal cells, cancer cells don't stop growing and dividing, this uncontrolled cell growth results in the formation of a tumor. Cancer cells have more genetic changes compared to normal cells, however not all changes cause cancer, they may be a result of it.
