In each drawing, there are lines between each atom and each molecule. What do you think the lines between atoms represent? The lines between molecules?

Answers

Answer 1

Answer:

Atoms are the smallest units of matter that still retain the fundamental chemical properties of an element. Much of the study of chemistry, however, involves looking at what happens when atoms combine with other atoms to form compounds. A compound is a distinct group of atoms held together by chemical bonds. Just as the structure of the atom is held together by the electrostatic attraction between the positively charged nucleus and the negatively charged electrons surrounding it, the stability within chemical bonds is also due to electrostatic attractions. To illustrate further, consider the two major types of chemical bonds: covalent bonds and ionic bonds. In covalent bonds, two atoms share pairs of electrons, while in ionic bonds, electrons are fully transferred between two atoms so that ions are formed. Let’s consider both types of bonds in detail.

Explanation:

Answer 2

Answer:Each straight line segment represents a bond, the ends and intersections of the lines are carbon atoms, and the correct number of hydrogens is calculated from the tetravalency of carbon. Non-bonding valence shell electrons are omitted in these formulas.Each line represents a single covalent bond (two shared electrons), so double lines represent a double covalent bond (four shared electrons). Covalent bonds are usually found in atoms that have at least two, and usually less than seven, electrons in their outermost energy shell, but this is NOT a hard and fast rule.

As we know that the leaves of plants are waterproof due to cuticle. On the same way, take
some pieces of paper of leaf size and make them waterproof. After completion, put half of these
paper pieces in cold water and half in hot water. Do all the pieces of paper remains waterproof?
Explain your observations and results with justifications

Answers

Answer:

No.

Explanation:

No, all the pieces of paper did not remains waterproof because expansion of paper occur due to high temperature of hot water. We know that materials expand when they experience high temperature and contract when they observe cold temperature. So the pieces of paper remains waterproof which were put in cold water while those were not waterproof if they are put in hot water.

Sunlight as an Electromagnetic wave:

Sunlight is a portion of the electromagnetic radiation given off by the Sun, in particular infrared, visible, and ultraviolet light. On Earth, sunlight is scattered and filtered through Earth's atmosphere, and is obvious as daylight when the Sun is above the horizon.

Sunlight is an electromagnetic wave that gains energy as it travels through the air to reach the person.

Difference Between Haploid And Diploid

Haploid cells contain only one set of Chromosomes (n).

Diploid, as the name indicates, contains 2 sets of chromosomes (2n).

A-Haploid cells are formed by the process of meiosis.

Diploid cells undergo mitosis.

B-In the higher organism, such as humans, haploid cells are only used for sex cells.

In the higher organism, such as humans, all other cells beside sex cells are diploid.

C-Examples of haploid cells are gametes (male or female germ cells).

Examples of diploid cells include blood cells, skin cells and muscle cells. These cells are known as somatic cells

Estas de acuerdo con la aplicación del principio de la física en ecología:¨la energía no desaparece ni se destruye, solo se transforma de una forma en esta otra¨ argumenta tu respuesta

Answers

Answer:

Esta afirmación es correcta ya que la ley de conservación de la energía es también aplicable a sistemas vivos  

Explanation:

La ley de la conservación de la energía (la cual es la primera ley de la termodinámica) indica que la energía no se puede crear ni se puede destruir, solamente se transforma, de un tipo a otro. La ley de la conservación de la energía es de vital importancia para entender la existencia del mundo natural. En ecología, la energía fluye de un nivel trófico a otro en forma de biomasa, es decir, dentro de la cadena alimentaria. Esta energía no se puede crear ni destruir sino que es almacenada en los organismos, los cuales representan sistemas abiertos que intercambian materia y energía con el medio. Una vez dentro del organismo, una parte de esta energía es transformada (en plantas, por ejemplo, la energía es convertida en enlaces químicos durante la síntesis de carbohidratos), mientras que otra parte de la energía se elimina al exterior (por ejemplo, se disipa en forma de calor), pero la energía no se crea ni se destruye.

B: destroying infectious germs
C: responding to external stimuli
D: obtaining moisture from the air

Answers

Answer:c

Explanation: The plant is responding to external stimuli by growing toward light like our eyes adjusting to the light in the dark......................

The correct answer is option c i.e. responding to external stimuli (phototropism).

Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.

what is phototropism?

Phototropism is one of the many plant tropisms or movements which respond to external stimuli.

Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.

Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light.

Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower—switch to reproductive mode—only at certain times of the year.

hence , a plant growing towards a light source is an example of phototropism.

Answer: I think It's D

The conclusion that can be made from the experiment is that the difference in growth between group 1 and group 5 seedlings shows that light impacts plants' growth.

Group 1 plants were exposed to 12 hours of light per day while group 5 plants were not exposed to light at all.

At the end of the experiment, group 1 plants produced a significantly higher number of leaves (8) and grow far taller (13 cm) than group 5 plants who were only able to produce a single leaf and grew 4 cm tall.

Also, the majority of group 1 plants were alive after 30 days of the experiment while the majority of group 5 plants had died.
