This is an example of Moro reflex.
The Moro reflex is an automatic response to a stimulus that is usually present in all infants. It occurs as a response to unexpected loss of support, in which the infant have the perception of falling. The Moro reflex begins at birth, and usually disappears after 3 or 4 months. The Moro reflex involves three different parts which are; spreading out the arms, unspreading the arms, and crying.
Answer:
The correct option is D. The average mass of plants exposed to 3 g of herbicide was 10g.
Explanation:
As the vertical axis is labelled as average plant mass, it will make the y- coordinate.
As the horizontal axis is labelled as Herbicide (g/plant), it will make the x-axis.
The coordinates for the given value are (3,10). 3 will be the value of the x- coordinate. Hence, it will show the average mass of the plant at the plotted point which will be 3 g.
10 will show the value of the y- coordinate which will be the amount of herbicide given to the plant.
Hence, Dis the correct option.
Answer:
Explanation:
Active transport is the movement of molecules or substance from a region of lower concentration to a region of higher concentration across a cell membrane against the concentration gradient.
Active transport requires cellular energy and are of two types:
primary active transport that uses adenosine triphosphate (ATP), and secondary active transport that uses an electrochemical gradient.
Active transport helps in the uptake of glucose in the intestines.
Cotransport or secondary active transport is the movement of molecules across a membrane it uses electrochemical potential difference that is created by pumping ions in or out of the cell.
Cotransport helps in the transport of glucose across the cell membrane.
Answer:
1. Improvements in telecommunication
2. Improvements in global travel
Explanation:
Global culture refers to <u>the transmission of beliefs, values, and ideas around the world that has a significant impact in the behavior of society</u>. This has been evolving through time, especially since the Industrial Revolution. Today, we are capable of communicating with other people as quickly and easy as ever in the history of humanity and this will keep evolving as technology evolves as well.
This evolution is due to science and technology, especially to the improvements in telecommunication, which <u>enables us to communicate with people from other countries through calls, social media messagings, e-mails, etc.</u>, and to the improvements in global travel, which is <u>much more accessible today than it was before, allowing individuals to move from one country to the other easily and constantly and improving socialization between people from different cultures and backgrounds.</u>
If thousands of glucose molecules were bonded together with equal numbers of sucrose molecules, the resulting substance could be described as a polysaccharide. They are <span>polymeric carbohydrate molecules composed of long chains of monosaccharide units bound together by glycosidic linkages.</span>
