Una galleta con chispas de chocolate y un helado con fresas, son ejemplos de:
A. Sustancia
B. Compuesto
C. Mezcla homogénea
D. Mezcla heterogénea
Una galleta con chispas de chocolate y un helado con fresas, son ejemplos de mezclas heterogéneas.
Una mezcla heterogénea está compuesta por dos o más sustancias diferentes, en donde es posible distinguirlas fácilmente ya que es una composición no uniforme. Las sustancias que lo forman no son representadas por ninguna fórmula química pero a su vez tienen sus propiedades particulares.
No se trata de una mezcla homogénea ya que la misma se trata de una mezcla uniforme en donde sus componentes no se pueden distinguir fácilmente. Esto significa que toda la mezcla posee las mismas propiedades. Unos ejemplos de mezcla homogénea son el agua de mar, café con azúcar, cerveza, etc.
Tampoco se trata de una sustancia ya que la misma se trata de cualquier componente que posee ciertas propiedades físicas y químicas estables que pueden detectarse fácilmente. Está compuesto de moléculas o átomos iguales, siendo ejemplos de sustancias: oxígeno, nitrógeno, etc. Además, no es posible separar una sustancia mediante ningún método.
Por último, tampoco se trata de un compuesto ya que el mismo se trata de una mezcla de distintos elementos que se combinan en una reacción, que pueden representarse mediante una fórmula química y que no pueden separarse o romperse salvo por procesos químicos puntuales. Es decir, está formado por moléculas con átomos distintos pero en la misma proporción, y siempre se trata del mismo tipo de molécula. Por ejemplo, el agua, que está formada por un átomo de oxígeno y dos de hidrógeno (H2O).
Para concluir, podemos decir que un elemento está formado por un solo tipo de átomo. Una sustancia se encuentra formada por mas de un elemento unido mediante un enlace químico. Un compuesto está formado por elementos distintos unidos, y una mezcla está formada por sustancias que pueden ser iguales o no, pero en cantidades aleatorias y que pueden separarse. En una mezcla homogénea, la composición es la misma en cualquier parte, y en la mezcla heterogénea la composición es variante.

Drag the items below into the box above in the correct order, starting with the first item in the sequence.
The retina of bats is made up primarily of rod cells, allowing bats to see well in dim light.
The optic nerve conveys the sensory information from the bat's eye to the visual cortex of the
brain.
Nitrogen is a necessary atomic element in proteins like visual pigments.
The musculoskeletal system of the bat acts on the information supplied by the nervous system
to capture prey.
The bat eyeball has adaptations to the retina and lens for low-light vision.
Rod cells have a high level of rhodopsin molecules, allowing visual acuity in low light.
Rhodopsin is a photopigment molecule that is highly sensitive to light.

The levels of biological organization are atomic, molecular, cellular, tissue, organ and systems of organs (such as nervous and muscular systems).
The correct levels of biological organization from the simplest to the most complex are:Nitrogen is a necessary atomic element in proteins like visual pigments;Rhodopsin is a photopigment molecule that is highly sensitive to light;Rod cells have a high level of rhodopsin molecules, allowing visual acuity in low light;The retina of bats is made up primarily of rod cells, allowing bats to see well in dim light;The bat eyeball has adaptations to the retina and lens for low-light vision;The optic nerve conveys the sensory information from the bat's eye to the visual cortex of the brain;The musculoskeletal system of the bat acts on the information supplied by the nervous system to capture prey.The nitrogen (N) atom is a fundamental component of biomolecules such as DNA (nitrogenous bases) and proteins (aminoacids).Rhodopsin is a light-sensitive protein pigment that is abundant in the rod cells found in the retina. This pigment (rhodopsin) is responsible for night vision.There are two types of photoreceptor cells located in the retina: rod cells and cone cells. Rod cells are required for vision at low light levels.The retina and lens are parts of the eye: the retina is a layer at the back of the eye; whereas the lens is located behind the iris and the pupil. The visual system is composed of the eye (i.e., the sensory organ) and different areas of the central nervous system which include the optic nerve, optic tract, and visual cortex.The musculoskeletal system and nervous system work together in response to stimuli such as visual motion or stimulus localization.Learn more in:

genetic crossings example
Answer:
Answer:Monohybrid Cross
Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.
Answer:Monohybrid CrossIn a monohybrid cross, the parent organisms differ in a single characteristic. Suppose, for example, two humans have children. The father has a widow's peak and the mother does not. A widow's peak is a dominant trait, meaning that if the child inherits the gene for this trait from one parent, that child will have a widow's peak regardless of the gene inherited from the other parent.Consequently, there are two possibilities. The child could inherit the widow's peak gene from his father, or he could inherit the non-widow's peak gene from his father. He will inherit a non-widow's peak gene from its mother, who does not have the widow's peak gene. In this particular monohybrid cross, there is a fifty-fifty chance that any given child will have a widow's peak.

In this particular monohybrid cross, there is a fifty-fifty chance that any given child will have a widow's peak.Dihybrid CrossIn a dihybrid cross, the parents differ in two characteristics you want to study. The pattern of inheritance here is somewhat more complicated. Suppose, for example, that you have two parents, one of whom has dimples and a widow's peak while the other has no dimples and no widow's peak. Dimples, like a widow's peak, are a dominant trait. Consequently, if these two traits are not linked, each child has a 1/4 probability of inheriting dimples and widow's peak, a 1/4 probability of inheriting dimples but no widow's peak, a 1/4 probability of inheriting a widow's peak but no dimples, and a 1/4 probability of inheriting neither. Keep in mind, however, that linked traits might exhibit very different patterns.

Explain two ways in which trachea is adapted to perform its function
Answer:
The trachea has a number of adaptations: cartilage rings in the walls of the trachea help to keep it open. ciliated epithelium and goblet cells to clean the air before it reaches the lungs.
The two approaches in which the trachea is adapted to carry out its characteristic:-
The trachea serves as a passage for air, moistens and warms it even as it passes into the lungs, and protects the breathing floor from an accumulation of foreign debris.The trachea is coated with a wet mucous-membrane layer composed of cells containing small hairlike projections referred to as cilia.What is the trachea?The trachea normally referred to as the windpipe is a tube approximately 4 inches long and much less than an inch in diameter in the majority. The trachea begins surely underneath the larynx (voice field) and runs down to the again of the breastbone (sternum). The trachea then divides into smaller tubes known as bronchi: one bronchus for each lung.

In this module you will learn to identify the plant parts and their functions. Why do you think plants are important in our life?
Answer:
: Green Plants are the sources of energy for all oraganism. They trap the solar energy and convert it into chemical energy in the form of food(starch)and they give off oxygen. if all green plants would not be there then all the herbivores will die due to starvation and so will the carnivores.
:Plants are really important for the planet and for all living things. Plants absorb carbon dioxide and release oxygen from their leaves, which humans and other animals need to breathe.
Also many plants are very useful in field medicine.
:Roots of plants and trees reduce soil erosion by holding the soil firmly.
Explain briefly George Wofan's hypothesis about the origin of the earth.
Answer:
In 1749 A.D. George Wofan, a French scientist, put forward the theory of evolution of the Earth for the first time. According to his theory the Earth along with other planets and satellites, was formed when a comet moving around the universe stroke the sun many years ago.
Explanation:
In 1775 A.D., a German philosopher Kant put forward another nebular theory, which was later improved by Laplace in 1796. According to him, there was a gaseous mass revolving around the earth. While revolving, this mass began to cool and shrinked resulting many smaller masses. These smaller masses began to move round the larger central mass. This central mass became the sun and over revolving bodies formed planet and satellites.
According to hypothesis proposed by Jeans and Jeffery in 1917 A.D., a big star orbiting round the sun finally approached it. The star with its own attraction caused a tide to be developed from the sun. As this fragmented tidal matter cooled, planets, satellites, etc. were formed and the solar system was created. In this process, the Earth was also formed.
Any two geological Era are as follows:
Palaeozoic era: Palaeozoic era was began from 540 million years ago and ended at 250 million years ago. In this era, the plants and animals were found tohave developed which was found from the studies of the fossils remained in sedimentary rocks. Similarly, it is also believedthat there was a change in atmosphere and whether. This era is divided into six periods.
Mesozoic era: Mesozoic era began from 250 million years ago and ended at 65.5 million years ago. In this era, different types of hills and mountains were formed. It is supposed that the vital conditions for the survival of life on land, water and air were formed. This era is divided into three periods.
