Adaptations generally affect a species through the fact that they make the species more genetically diverse. Thus, the correct option is C.
What is species?Species may be defined as a group or collection of organisms that can significantly reproduce with one another in nature in order to produce viable offspring. The process of speciation is responsible for the formation of new species within any geographical location.
On the other hand, adaptation may be characterized as a continuous process of modification that an organism performs in order to make them fitter for existence in a particular geographical location. This process of modification in the long term can definitely lead to speciation where new species may arise.
Therefore, adaptations generally affect a species through the fact that they make the species more genetically diverse. Thus, the correct option is C.

Which traits are shared by all eukaryotic cells, and what are the three major lines of evidence that mitochondria arose from endosymbiosis with proteobacteria?
(Penn Foster)
The plant cell, like the animal, is eukaryotic, that is, it has a nucleus delimited by a nuclear membrane (karyotheca). In addition to this characteristic, these cells have a plasma membrane and cytoplasm, structures common to any cell.
What are the three main lines of evidence that mitochondria arose from endosymbiosis with proteobacteria?"Some organelles (mitochondria and chloroplasts) existing in eukaryotic cells emerged thanks to a symbiotic association. It is believed that mitochondria and chloroplasts are descendants of prokaryotic organisms that were captured and adopted by some cell, thus living in symbiosis."
With this information, we can conclude that After engulfing the cell, it remained maintained in the cytoplasm of the host cell without degradation. The two organisms then began to live in symbiosis and were later unable to live in isolation. The prokaryote likely benefited the host cell with the process of respiration (mitochondria) and photosynthesis (chloroplast), and the host cell provided protection and nutrients.

What is theory of abiogenesis?Theory of abiogenesis was a concept proposed by Huxley in which he suggested that the life forms on the earth have been formed spontaneously from the reaction between the nonlife components on the earth.
The complex living forms were believed to be evolved from the simple forms through various biochemical interactions. This was later demonstrated by Urey and miller in their experiment.

c) The potato cube that goes into the 0% water solution weighs 2.78 grams
d) The potato cube that goes into the 0% salt solution weighs 2.78 grams
These are the weights of a potato cube after an experiment of osmosis.
Osmosis is the naturally occurring diffusion or passage of water or other solvents over a semipermeable membrane (one that prevents the passage of solutes, or dissolved compounds). The crucial biological mechanism was initially in-depth investigated in 1877 by German plant physiologist Wilhelm Pfeffer.
Previous researchers had conducted less precise examinations of leaky membranes (such as animal bladders) and the transport of water and escape chemicals through them in opposite directions. Thomas Graham, a British chemist, coined the term "osmose," which is still used to refer to the process, in 1854. A solution will tend to become more diluted by absorbing solvent through a membrane separating it from the pure solvent if the membrane is permeable to the solvent but not to the solute.

An isotonic environment outside a cell has _______% salt, the same as the inside of the cell.
An isotonic environment outside a cell has same amount of salt, the same as the inside of the cell.
What is isotonic solution?Isotonic solutions are the ones that have the similar concentration of water as well as solutes as cell cytoplasm. Because there is no net gain or loss of water, cells in an isotonic solution will neither shrink nor swell.
When a cell is immersed in an isotonic solution, there is no net flow of water into or out of the cell, and the volume of the cell remains constant.
If the concentration of solutes outside the cell is the same as the concentration inside the cell and the solutes cannot cross the membrane, the solution is isotonic to the cell.
Thus, it has same percentage of salt inside and outside.

First, there is carbon geoengineering, often known as carbon dioxide removal (CDR). The other is solar geoengineering, which is additionally referred to as solar radiation management (SRM), albedo alteration, or sunlight reflection.

Define extinction and explain how the fossil record can give evidence of an extinction event.
Answer:
i think it's helpful for you The fossil record, however, describes sudden, global extinctions that affect many species. These dramatic events are known as mass extinctions. Some populations seem more vulnerable than others: tropical forms of life have been drastically affected, while land plants tend to be highly resistant to mass extinctions.hi Mary can we friends ?
Extinction refers to the complete disappearance of a species or group of organisms from the Earth. Extinction can be caused by a variety of factors such as climate change, habitat destruction, competition, predation, disease, and human activities such as hunting and pollution.
Why fossil record is one of the most important sources of evidence?The fossil record is one of the most important sources of evidence for extinction events. When a species goes extinct, its fossils can still be found in the rock record, often in a particular layer of sediment that corresponds to the time period when the extinction occurred.
By studying the fossil record, scientists can identify periods in Earth's history when there was a sudden and widespread disappearance of species, which is known as a mass extinction event.
For example, the fossil record shows that there have been five major mass extinction events in the history of life on Earth, with the most famous being the extinction of the dinosaurs at the end of the Cretaceous period.
The extinction of the dinosaurs is marked by a distinct layer of sediment that contains high levels of iridium, which is rare in Earth's crust but is abundant in asteroids and comets. This layer of sediment suggests that a large asteroid impact may have triggered the extinction of the dinosaurs and many other species.
Overall, the fossil record provides valuable evidence for understanding the history of life on Earth, including the occurrence and causes of extinction events.

when tissue work together they are called
Answer:
Organs
Explanation:
Tissues are an aggregate of similar cells and cell products forming a definite kind of structural material with a specific function, in a multicellular organism. A organ is a grouping of tissues into a distinct structure, as a heart or kidney in animals or a leaf or stamen in plants, that performs a specialized task.
To explain more,
Organs are collectives of tissues that function as a unit. The heart, lungs, skin, and stomach are just a few examples of organs. Systems are what occur when organs cooperate. Your heart, lungs, blood, and blood arteries, for instance, cooperate. The circulatory system is made up of them.
The human body is made up of eleven different systems: the muscular, respiratory, digestive, integumentary (skin), skeletal, circulatory (or cardiovascular), excretory (or urine), reproductive, neurological, lymphatic, and endocrine systems. Every system has a unique function.
To keep you healthy, every body system must cooperate. Together, your muscles and bones support and move your body. Air is used by your respiratory system to take in oxygen. Carbon dioxide is also expelled.
Your digestive tract takes nutrients and water from the food you eat in to your body.
Your body's cells receive oxygen, water, and nutrients through your circulatory system. Your epidermis, excretory system, and respiratory system all function to remove wastes from your cells.
Your nervous system uses electrical impulses to regulate all of these processes. Other systems in your body are impacted if one system isn't functioning properly.
Imagine your body as a structure. A building has a support system, an electrical system, a heating and cooling system, and a plumbing system. Other systems in a facility may be impacted if one system malfunctions.
Consider the electrical system of a building as one illustration. Imagine a mouse gnawed a furnace's electrical line. The heating system wouldn't function without power. The plumbing system can be impacted if this occurs during really cold weather. A frost might cause water pipes to explode. The support system of the structure would be harmed if a lot of water spilled through the walls. Your body's systems must cooperate, much like those of a skyscraper.
Thanks,
