Answer:

C

Explanation:

A. no... the finches were living in different environments making them become less similar over time.

B. no... the Galapagos are long way from Africa... not possible

C. yes... This is true ... the size and shape of the beaks makes a big difference in the type of food  the finches could eat. Seed types would change as climate change and finches would with the best beak size for the food available would survive.

D. no very unlikely. DNA Evidence show that the finches were from one common ancestor

The image shows a magnified view of a leaf's surface with the stomata visible. What’s the significance of these structures in th
Deffense [45]

The correct answer is option (d) They allow the exchange of gases between cells in the leaf and the external environment.

Stomata are the tiny openings present in the epidermis (outer layer of cells) of the leaf. They have a pore which is guarded by the guard cells which controls the opening and closing of the stomata. Air enters and exits through the stomata.

The main funtion of stomata is to facilitate the gaseous exchange. The gas exchange that occurs when the stomata are open helps in the process of photosynthesis. During photosynthesis, carbon dioxide is taken in from the atmosphere and oxygen is released as a by-product of photosynthesis. The glucose produced is converted into the starch and stored in the leaves.

Also, water vapour diffuses through the stomata into the atmosphere by a process called the transpiration.

Thus, stomata are the structures that are mainly involved in the gaseous exchange between the cells of the leaf and the atmosphere.

How salt dissolves in water
lana66690 [7]

Answer:

Water molecules pull the sodium and chloride ions apart, breaking the ionic bond that held them together. After the salt compounds are pulled apart, the sodium and chloride atoms are surrounded by water molecules, as this diagram shows. Once this happens, the salt is dissolved, resulting in a homogeneous solution.

Angelina_Jolie [31]

Answer:

Constant variables

Explanation:

Elaina's investigation lacked the critical ingredient of constant variables which are important components of every scientific investigation. In every research, there are 3 important variables, namely:

1. Dependent variables: the actual variable to be measured during the course of investigations and whose values are dependent on another variable (independent variable) supplied by the investigators.

2. Independent variable: one of the variables that are supplied by investigators whose values are often manipulated to see the kind of changes it will cause to the dependent variable.

3. Constant variables: other variables that are neither independent nor dependent but constant for all the various experimental groups in investigations.

Q6.7. During many epidemics, health-care professionals emphasize the importance of
Serga [27]

During many epidemics, <u>healthcare </u>professionals emphasize the importance of  community mitigation strategies, such as wearing masks, frequent hand-washing, and social  distancing because these strategies help <u>reduce </u><u>transmission </u><u>even when drug-based treatments and vaccines are  unavailable.</u>

It is of <u>vital </u>importance in cases of epidemics to implement strategies such as:

  • Hand-washing
  • Wearing masks
  • Social distancing

in order to better protect our communities and ourselves.

Frequent hand-washing serves to<u> eliminate the presence of a </u><u>pathogen</u> <u>from the surface of your hands</u>, reducing the risks that it will find entry into your organism or land on a surface with which others will come into contact. Should you or someone else contract the pathogen anyways, wearing a mask can help to reduce or deny the possibility of transmitting the disease.

Finally, should both previous measures fail, meaning that the virus or pathogen has infected an individual and penetrated the masks, social distancing can act as a <u>final barrier</u> that the pathogen will rarely be able to surpass, given that most pathogens <u>cannot remain airborne over large distances. </u>

For these reasons, healthcare professionals emphasize the importance of these strategies because they help reduce transmission <u>until vaccines or drug-based treatments become  available and </u><u>herd immunity </u><u>can be reached. </u>
