Lloyd’s lab partner is looking down into a test tube while he heats the contents by using a flame. Which action should Lloyd recommend to his partner if heating must continue?
Wear safety goggles while looking into the opening of the test tube.
Cover the opening of the test tube so that no materials can boil out of it.
Move the test tube so that the opening is pointing away from all students.
Put the test tube in a hot water bath so that no water can enter its opening.
The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.
Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.

How is the Nucleus like a brain?
Answer:
The nucleus contains the DNA of the cell which can be thought of as the brain of the cell.
The nucleus responds to stimuli via receptors which can be primary or secondary. Basically, an external ligand (hormone, protein, nutrient, etc) binds to the surface receptor of a cell, this, in turn, causes the receptor to release a messenger (most of the time circular AMP (cAMP)) which binds to a secondary receptor which is either directly inside the nucleus or on the nuclear envelope. Finally. the portion of the DNA which is responsible for the protein to respond to the ligand is activated and begins transcription.
The activated DNA section (gene) produces mRNA which in turn produces a protein in response to the ligand.
On top of this, the entire cell cycle of rest, growth, and division is controlled by the nucleus.

a essay explaining why i choose a certain university
Answer:
Because the facilities here for my subject are second to none” – this shows that your subject has been at the forefront of your mind when making a sensible choice of university, again demonstrating your level of commitment to it. You can mention specific facilities to show that you’ve read into it thoroughly.
“Because I liked the approach this university takes to my course” – even within the same subject, every university takes a slightly different approach to the way it’s taught and structured. The university question is another good opportunity to show that you’ve really thought about the course and gone to the effort of finding a university whose approach to the subject you agree with. You can even name specific modules that set this university’s course apart from the others offering the same subject.
Along similar lines, you could also mention the university’s great reputation for your subject, or the presence of certain lecturers you feel inspired by (though don’t let this last point dominate your answer; lecturers often move about or go on sabbatical, so even if there’s a particular academic you admire, they may not end up teaching you).

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 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.

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:

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.

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.
