An abiotic factor is a non-living part of an ecosystem, including its physical and chemical aspects.

Examples of abiotic factors include:

Sunlight: It is the source of energy for plants and affects animal habits.

Temperature: It affects the life of every species, determining where they can exist, afects metabolic reactions and is determinant for the variation of plants and animals.

Atmosphere: It sustains life on earth protecting animals from UV radiation for example.

Humidity: it affects the internal balance of organisms.

Soil: It is a source of nutrients for plants, therefore its composition affects their functions

The depth of a body of water can also be considered an abiotic factor. It affetcs for example the type of species that can live there and it determines the preassure they would have to withstand.

b. The cell membrane allows certain materials to pass into or out of the cell. There are three basic ways that the cell membrane preserves homeostasis: making it possible for the membrane to move fluidly.

Osmosis, or the flow of water from a high concentration to a low concentration, can be controlled. keeping certain ion concentrations constant.

The function of the cell membrane is to control the flow of substances into and out of the cell. The membrane of the cell must be passed through for any materials to enter or exit. Based on what is thought to be the ideal concentration level for that material, the membrane determines whether that material will be permitted passage. The concentration of water and other ions is typically the main factor on which the cell membrane depends.

Answer:

False. They have tendons. Arm and palm have muscles I believe, and that's what they rely on (the tendons).

The five evidences that support the theory of evolution are: Fossils, Anatomy, Embryology, Molecular Biology (or Biochemistry), and Biogeography.

Fossils show the physical change in a species over time, suggesting evidence for evolution. For an example, we can trace the origins of dolphins and whales all the way to a four-legged, dog-like hoofed mammal from about 50 mya. These mammals were fish eaters and so decided to spend a lot of time in the water. In fact, they spent so much time in the water, that in a few million years, they evolved a longer body and webbed feet. Then another few million years passed and they swapped their webbed feet for flippers and swapped their tail of a fin. Eventually, we get a fish-like mammal that once walked on land.

For anatomy, or structures, there's three types of structure comparisons: Homologous structures, Vestigial structures, and Analogous structures (or Convergent Evolution). Homologous structures show similarities between the structures between species, but serve different purposes. For an example, all mammals share common features within their arms, such as having 5 fingers. However, they serve different purposes, from whale fins for swimming, to bat wings for flying, to human hands for grabbing and for using tools.

Vestigial structures were structures that once served a purpose and have been reduced in size/power to the point where it's useless. For an example, large theropods such as the T. Rex spent so much time evolving more jaw muscles and biting power, that they sacrificed their arm muscles for such power. This explains why their arms were so short.

Another example would be ratites, flightless birds such as ostriches, emus, and cassowaries (penguins and kakapos are from a different group). They spent so much time evolving powerful legs as well as evolving in size, that there was no need to fly when they could just run with their improved legs. And also the fact that they're too heavy to even fly anyways.

Analogous structures is the similar functions of structures between species, but have separately evolved these functions. For an example, the wings from insects, birds, bats, and pterosaurs are very similar in shape and can be used to fly, but they've evolved separately. For an example, birds use feathers to fly while bats and pterosaurs use/used (pterosaurs are extinct) membrane between their bones to fly. Although they do have strikingly similar evolutionary histories, with their ancestors starting off as tree dwellers, they've evolved their flight abilities separately during different earth periods.

Embryology is evidence for evolution by using embryos from different species to suggest a common ancestor. For an example, we can prove that we're more related to whales than to fish by using embryos. The fish embryo will evolve gills while the embryos of humans and whales will not, since we do not breath by extracting oxygen from water.

Molecular biology is a more recent way of providing evidence for evolution. By taking the DNA from cells from different species, we can get an estimate of how related one species is to another. The more similar amino acid sequences are between species, the more recent their common ancestor is. For an example, by comparing amino acid sequences between humans and chimpanzees, we get an estimated amount that we once shared a common ancestor seven million years ago. Without molecular biology, we would still be digging for fossils to find that number.

Biogeography is the geographic distribution of species on earth that can be explained by evolution. For an example, we can tell that Australia separated first from Pangea rather than Asia or North America since Australia doesn't have bears while the Asia and North America do, with China having pandas and North America having brown and black bears. And also with the fact that Australia is the only continent with monotremes (egg-laying mammals like the platypus).

Similar to biogeography, there's also direct observation, which is evolution that has happened in our own eyes. An example would be the underground London mosquito. Mosquitoes usually target birds like pigeons. But after an underground tunnel was built in London, some mosquitoes managed to get inside and instead of birds, they targeted, mice, rats, and of course, humans. After only a few hundred years, a mosquito from the underground tried to mate with another mosquito from land and they could not, simply because they were different species. This shows that their new choice of feeding on mammalian blood has actually altered their DNA and created a new species, during the existence of humanity!

Conservation efforts must go beyond large isolated national parks and include innovative approaches that consider the human impact, such as community-based conservation, landscape connectivity, and sustainable resource management.

The limits of big, remote national parks in adequately safeguarding biodiversity from human interference are highlighted by Dr Hadly's findings. The article offers fresh approaches to conservation, including community-based conservation, which involves local groups in management and decision-making, landscape connectivity to create corridors for species migration, and sustainable resource management to strike a balance between meeting human needs and ecological preservation.

These cutting-edge strategies emphasise teamwork to protect biodiversity in a changing environment and acknowledge the interdependence of human and natural systems.

Answer:

The term that describes the relationship in which one organism lives inside the other one is endosymbiosis.

Explanation:

Answer:

DNA (Deoxyribonucleic acid) is a double-stranded helical structure consisting of nucleotides, which are composed of a sugar molecule (deoxyribose), a phosphate group, and a nitrogenous base (adenine, thymine, guanine, or cytosine). The structure of DNA plays a crucial role in the process of semiconservative, accurate replication.

Semiconservative replication is the process by which DNA replicates, resulting in two daughter strands, each with one original strand and one newly synthesized strand. This type of replication ensures that the genetic information is preserved and accurately passed on from generation to generation.

The structure of DNA allows for semiconservative replication to occur in the following way:

The two strands of the double helix are separated by an enzyme called helicase, which breaks the hydrogen bonds between the complementary nitrogenous base pairs.

Each separated strand serves as a template for the synthesis of a new complementary strand by a DNA polymerase enzyme. The DNA polymerase reads the template strand and adds nucleotides to the new strand according to base pairing rules (A-T and C-G).

Because the two strands of DNA are antiparallel, meaning they run in opposite directions, the newly synthesized strand is elongated in the opposite direction to the template strand, from the 5' to the 3' end.

The result is two daughter strands, each consisting of one original strand and one newly synthesized strand.

The semiconservative replication process relies on the complementary base pairing between the nitrogenous bases of the two strands. This means that during replication, each original strand serves as a template for the synthesis of a new complementary strand. The pairing of adenine with thymine and cytosine with guanine ensures that the information is accurately replicated and preserved.

Explanation:

Another level of genetic variation is added by random fertilization , since we can't predict which sperm will fertilize a given egg.

A new individual organism or progeny is created when two gametes are fused during fertilization, often referred to as fertilization, impregnation, syngamy, and generative fertilization. The term "fertilization" is often used colloquially to refer to pre-gametic processes like pollination and insemination. The cycle of fertilization and development of new individuals is called sexual reproduction. In the process of vegetative fertilization, the haploid male gamete of an angiosperm fuses with two haploid polar nuclei to create a triploid main endosperm nucleus.

A pincurl with an open circle has the ability to produce a wider wave pattern with uniform curls. This is because the open circle allows for more hair to be wrapped around the curler, resulting in a looser and wider wave pattern. Additionally, the uniform curls are achieved because the open circle allows for consistent placement and tension of the hair around the curler.

However, it is important to note that the size and strength of the wave also depends on the size of the pincurl and the amount of tension applied while wrapping the hair around the curler. A larger pincurl with less tension will result in a fluffier effect, while a smaller pincurl with more tension will produce a smaller and stronger wave.

Overall, pincurls are a classic hairstyling technique that can create a variety of effects depending on the technique and tools used. They are a great option for achieving vintage-inspired looks, as well as providing volume and texture to modern hairstyles.
An open circle pincurl can produce the following effect:

d. Wider wave pattern with uniform curls

Here's a brief explanation to help you understand:

1. Pincurls are a traditional technique for curling hair, where small sections of hair are dampened, rolled up, and secured with a hairpin.

2. Open circle pincurls involve rolling the hair around your finger without overlapping it, creating an open circle or "C" shape.

3. This open circle shape allows for a wider wave pattern to form as the hair dries and sets.

4. The uniform curls are a result of the consistent shaping and spacing of the open circle pincurls throughout the hair.

So, by using open circle pincurls, you can achieve a wider wave pattern with uniform curls in your hairstyle.

The boundary between the thoracic cavity and abdomen is called the diaphragm.

The diaphragm is a thin, dome-shaped muscle that separates the chest cavity from the abdominal cavity. It plays a crucial role in respiration by contracting and relaxing to control the flow of air in and out of the lungs. The diaphragm also helps to protect the organs in the thoracic and abdominal cavities from injury. The esophagus, major blood vessels, and nerves pass through the diaphragm to connect the chest and abdominal organs. Dysfunction of the diaphragm can cause a range of medical issues, including breathing difficulties and gastrointestinal problems.

A nucleotide consists of a sugar molecule (either ribose in RNA or deoxyribose in DNA) attached to a phosphate group and a nitrogen-containing base. The bases used in DNA are adenine (A), cytosine (C), guanine (G), and thymine (T).

Explanation:

Nucleotides, which are genetic building blocks, are composed of sugar, a phosphate group, and a nitrogen base.

A pentose sugar, a phosphate, and a nitrogenous base make up the organic compound known as a nucleotide. They function as monomeric units of the deoxyribonucleic acid and ribonucleic acid polymers, which are both crucial macromolecules for all kinds of life on Earth.

DNA contains the bases adenine (A), cytosine (C), guanine (G), and thymine (T). These bases come in particular combinations (A with T, and G with C). Three components make up a nucleotide. Adenine, Cytosine, Guanine, or Thymine are the four different nitrogenous bases that make up the first one. Thymine is swapped out for uracil in RNA. Purines or pyrimidines are these nitrogenous bases.
