The science is the investigation of phenomenan and biology is a branch that studies ecosystem and living entities.
Science is the subject that deals with the reasons behind the phenomenon happening in the world like the interactions between the biotic and abiotic factors and abiotic phenomena like earthquake, tsunami, volcanoes , and also find the reasons behind the formation o mountains, continents, oceans, valleys, rivers and how the processes of gravitation, chemical changes take place and also it deal s with the reasons behind the reproduction, variations, evolution,, whereas the biology mainly focuses on the living entities and their interactions wirh the abiotic factors like temperature, water, though , light intensity, etc so it studies biosphere and ecosystem and study of it also called as ecology and all these are important because they will let us know that whatever is happening is due to a reason and how it can be used in research to develop a better world for living with desirable improvemnet s and also it helps in addressing the social issues related environmnt like global warming , glacier melting , pollution , inavsion , overexplouitation , climate changes , habitat loss etc.

Generally, animals cannot digest (hydrolyze) the glycosidic linkages between the glucose molecules in cellulose. how then do cows get enough nutrients from eating grass?
Microorganisms in their digestive tracts hydrolyze the cellulose to individual glucose units.
Cellulose- The stable formation of plant cell walls is greatly aided by cellulose, a hard, fibrous, and water-insoluble polysaccharide. The fibrils (bundles of microfibrils) and microfibrils (bundles of polysaccharide) made up of cellulose chains make up the plant cell wall.
Glucose- The primary form of sugar in the blood, glucose serves as the body's cells' principal source of energy. Glucose may be produced by the body from other chemicals or it can be obtained from the meals we eat. The circulation carries glucose to the cells.

The numbers of some receptors found in the brain may vary during the day by 50%.
All organisms have a natural circadian rhythm, which is one of the key distinguishing characteristics of organisms. They are present in most biochemical and molecular processes, from transcription of genes in the cell nucleus to cell cycle regulation, and are heavily involved in physiological and behavioral mechanisms. The central circadian regulatory nucleus in mammals that responds to environmental light-dark cycles is known as the suprachiasmatic nucleus (SCN) and is located in the anterior hypothalamus of the brain. A set of clock genes form a transcription-translation feedback loop at the SCN, a key mechanism of circadian rhythms. Although the SCN is essential for the generation of mammalian biological rhythms, it is not the only nucleus in which clock genes are expressed and regulated.Therefore, the correct answer is 50%.

The principle of uniformitarianism does not state that sedimentary rocks are deposited in horizontal layers. So the statement is false.
What is the principle of uniformitarianism?Grasp Earth's history requires an understanding of uniformitarianism. However, uniformitarianism was not the dominant idea before 1830. Up until that point, experts believed in catastrophism.
According to catastrophe theory, the landforms that can be seen on Earth's surface, such as mountains, were created by sudden, drastic changes, or catastrophes. Uniformitarianism's detractors may use the term "no-analog alterations" when speaking of historical climates.
According to this theory, there may not be communities or environmental factors present on Earth now that existed in the past. In the end, James Hutton and Charles Lyell's observations and research led to a challenge to the catastrophism theory. Hutton (1726–1797) was a farmer and naturalist from Scotland.

the sense of equilibrium maintains the stability of the head and body when they are motionless. the sense of equilibrium balances the head and the body when they are suddenly moved or rotated.
The sense of static equilibrium maintains the stability of the head and body when they are motionless. The sense of dynamic equilibrium balances the head and the body when they are suddenly moved or rotated.
Static equilibrium occurs when a body is at rest. There are two forces acting upon the body during static equilibrium, but they occur in opposite direction, and as a result the body remains static. For example, when an organism stands still in its position, it is acted upon by the force of gravity downwards and normal force upwards and thus remains in static equilibrium.
Dynamic equilibrium occurs when a process is going on. It detects the angular acceleration of the movement of head. In humans, the semicircular canals help in maintaining the dynamic equilibrium.

6.4 X 10⁷ different proteins, each composed of 6 amino acids, can be constructed using the 20 different amino acids found in proteins.
The majority of amino acids are represented by more than one codon because there are only 20 distinct amino acids but 64 potential codons.
The 20 different amino acids can be put together in a wide variety of ways to create a wide range of proteins.
The formula determines the number of distinct proteins made up of n numbers of amino acids = 20ⁿ

Describe the process of how heat transfers from within the Sun starting in the core and moving outward.
Answer:
Hope it helps
Explanation:
The energy produced through fusion in the core moves outward, first in the form of electromagnetic radiation called photons in the so-called radiative zone. Next, energy moves upward in photon heated solar gas. This type of energy transport is convection. In other words, energy is radiated out from the core first, then carried to the outer layers by convection. Energy is carried out from the core by convection first, then radiated to the outer layers.
Which population would be most likely to undergo relatively rapid allopatric speciation?
Allopatric speciation would be fastest in the herd of wild horses.
What is allopatric speciation?
When groups of a same species are geographically separated from one another, allopatric speciation takes place. Populations gradually change into new species through a process called speciation.
A herd of wild horses was shipped from Wyoming to a little desert island off the coast of California that had never before had any. After then, no more horses arrive at the island. The new population is tiny (reproductively) and geographically separated from neighboring populations, both of which tend to favor allopatric speciation.
