My family has an orange and white female cat, which is uncommon. Please describe her possible inheritance. (You may need to research this!)
Answer:
That orange and white cat next door could be an American Bobtail, a Persian, a Munchkin or even a Maine Coon! Their orange color comes from a predominance of a pigment called pheomelanin. This is the same pigment that makes some humans “redheads”.
Explain why it is incorrect to state the individuals can "adapt” to their environments
Evolution does not occur when an organism adapts to its surroundings.A sexually reproducing creature must mate with other members of its species even though an individual organism may be more adapted to its environment. Therefore, by definition, it is not a new species.
What would happen if living things didn't evolve or adapt to their surroundings?
However, extinction is likely to occur if conditions change faster than a species can adapt and if individuals from that species lack the characteristics necessary to live in the new environment. To be able to survive, all species must be able to adapt to their environment.This entails adapting in order to survive the ecosystem's climatic conditions, predators, and other species that compete with them for resources like food and habitat. Natural selection is the process that results in this.Natural selection causes a species' nature to progressively change so that it can fit into the niche.A species can persist for a very long time before going extinct if it becomes extremely well adapted to its habitat and if the environment does not change.Each environment that an organism inhabits is distinct from the others.Its natural habitat is inside this environment.Here, an organism can find everything it needs to exist, including food, water, refuge from the elements, and a location to reproduce its young.To be able to survive, all species must be able to adapt to their environment.This entails adapting in order to survive the ecosystem's climatic conditions, predators, and other species that compete with them for resources like food and habitat.An adaptation is a modification or behavior change that an organism makes to aid in its survival.To learn more about habitats and how various plants and animals function, click on the links provided here.A creature may change how it interacts with its environment.Similar to how bird limbs have evolved into wings or how the cheetah is built for swift running, it might be a physical or structural adaptation.To learn more about environment adoption refer

What proteins are involved to produce eyes color?
Answer:
yurrrrrrrrrrrrrrrrrrrrrrrrr
Explanation:
Answer:
The protein produced from the OCA2 gene, known as the P protein, is involved in the maturation of melanosomes, which are cellular structures that produce and store melanin. The P protein therefore plays a crucial role in the amount and quality of melanin that is present in the iris.

Answer:
1. Homeostasis.
2. Osmoregulation.
3. Thermoregulation.
4. Endotherm.
5. Ectotherm.
6. Excretion.
Explanation:
1. The level of glucose in a person's blood stays relatively constant even after he or she eats a sweet dessert. This is an example of homeostasis, which is the maintenance of relatively constant internal conditions despite fluctuations in the external environment. Homeostasis can be defined as a process through which a living organism maintains a steady or stable physical, internal and chemical environment that is ideal to enhance life and proper functionality.
2. The maintenance of internal water and solute concentrations within a narrow range is called: osmoregulation. Normovolemic describes the situation in which a living organism maintains a normal volume or amount of blood in the body.
3. The maintenance of internal temperature within a narrow range is called: thermoregulation. Temperature can be defined as a measure of the degree of coldness or hotness of a physical object. It is measured with a thermometer and its units are Celsius (°C), Kelvin (K) and Fahrenheit (°F).
4. An endotherm, such as a pigeon, is an organism that gains body heat primarily from its own metabolism. It is also referred to as homotherm and it involves maintaining a constant body temperature.
5. An ectotherm, such as a salamander, is an organism that gains body heat primarily by absorbing it from the environment. Thus, an ectotherm have limited abilities with respect to regulating its body temperature.
6. The disposal of nitrogen-containing wastes, as through urination, is called: excretion. Glomerular capsule is also referred to as Bowman's capsule and it can be defined as a cuplike sac (structure) with a double wall, which makes up the tubular part of a nephron within the kidney of mammals. It is saddled with the responsibility of first filtering blood (ultrafiltration) under pressure to generate urine in the mammalian kidney.

why are owls considered keystone predator
Explanation:
Keystone species are animals that help manage other animal species by controlling population numbers and biodiversity within an ecosystem. The impacts of keystone species are usually greater than their numbers.
owls can be a great benefit to places where rodent populations are high. Dense urban areas often suffer from an abundance of rats and mice spreading disease, and rural agricultural communities have their crops consumed and soil eroded from burrowing voles and field mice. Without owls, and other top predators, rodent populations could explode and exacerbate the effects they produce.
Answer:
the owl is a keystone species, as many other birds. and it gives them the nutrients they need when they eat the bird and it mangeges the population of the other species:)

Explain the basic process of transcription. Include a description of the major intracellular structures involved.
Answer:
Transcription is the cellular process of RNA synthesis by decoding the information contained in a DNA fragment
Explanation:
Transcription is the process by which the genetic information contained in a fragment of DNA called 'gene' is used as a template to synthesize an RNA molecule, usually, a messenger RNA (mRNA), which is subsequently used to synthesize a protein by the process of translation. In eukaryotic organisms, transcription involves a DNA template strand, which contains both non-coding (i.e., promoter, introns) and conding (i.e, exons) regions, and an RNA polymerase that adds nucleotides to the growing RNA strand using as a template a DNA strand. Both in prokaryotes and eukaryotes, transcription occurs in three basic steps: 1-initiation, where DNA strands separate, 2- elongation, where the RNA polymerase moves on the DNA sequence to synthesize an RNA molecule, and 3-termination, where transcription terminates depending on the sequence in the RNA (eukaryotic transcription has an additional step known as RNA processing).
I need help in writing an essay about the rise of global temperatures over the past century
Answer:
Essay about the rise of global temperatures over the past century.
Explanation:
The rise of global temperatures over the past century is the major issue which occurs due to human activities. The use of fossil fuels in vehicles releases huge amount of carbondioxide gas in the air while burning. Carbondioxide gas is a green house gas which blocks the reflected solar radiation to go away in the space. These solar radiation remains in the surface which increases the surface temperature of the earth. This rising in the surface temperature is responsible for the melting of glaciers that leads to the rise of sea level which is a threat for coastal regions. This melting of glaciers also causes floods in the regions so that's why the it is a major issue.

1. Each branching point represents a point in evolutionary history where an ancestral evolutionary lineage gave rise to a new lineage. The most recent common ancestor shared by all lineages in this cladogram is
represented by the number
Enter... The most
recent common ancestor shared only by gymnosperms and angiosperms is represented by Enter..
Hello. You did not present the cladogram to which the question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A cladogram is the representation of the evolutionary relationships between living beings, showing ancestry and the genetic relationship between them. The cladogram is represented by lines and dots. The lines represent the evolutionary time and the dot between them represents the ancestor of a new species. In this case, to answer your first question, we can consider that the most recent ancestor of all species is the ancestor of the central line. However, the most recent ancestor, shared only by gymnosperms and angiosperms, is the one that is in the dot closest to the lines that represent gymnosperms and angiosperms.
