In the most general terms, the study of sensation and perception is called psychophysics, a term that was first coined by ________.

Answers

In the most general terms, the study of sensation and perception is called psychophysics, a term that was first coined by Gustav Theodor Fechner.

In the field of science, psychophysics can easily be described as a combination of stimulus and sensation as these two terms are often considered to be one, but are different. The branch of psychophysics combines the branch of psychology with the branch of physics.

The term 'psychophysics' first came forward by Gustav Theodor Fechner.  He was a well-established person in the field of psychology as well as physics. The reason behind bringing the concept of psychophysics, according to Fecher was that the relation between stimuli and sensation needs to be understood.

Over time, the complex ways in which the mind of a person, and its perception relates to the stimuli are studied under the complex branch of psychophysics.

If a cell that is composed of 60% water is placed in a solution that is 90% water, that means that the cell is ______% solute while the solution is ____% solute.

Answers

If a cell that is composed of 60% water is placed in a solution that is 90% water, that means that the cell is 40% solute while the solution is 10% solute.

The calculation can be made by the formula using,

Solute + Solvent = Solution

Solute- A substance that dissolves in a solution is referred to as a solute. In fluid solutions, the solvent content is greater than the quantity of solute.

Solvent- A material that can dissolve solutes, that are molecules and compounds, is referred to as a solvent.

Solution- The majority of life's chemistry takes place in aqueous solutions, or mixtures in which water acts as the solvent. A solution is a homogenous mixture of a solvent and a solute.

Answers

Answer:

a.

Explanation:

After 8 hours of sleep and before eating the hormone that will be secreted is and the cell secreting it is : (A)  I and IV   i.e. Insulin and Beta cells

After waking up from 8 hours of sleep the body might become hungry therefore before eating and just after sleeping for a long time the hormone that will be secreted is the "hunger " hormone known as the Ghrelin which is produced in the stomach.

Ghrelin hormones modulates the secretion of insulin and Insulin receptor signalling in the beta cells of the pancreas. Therefore the hormone that will be secreted after long sleep and before eating is Insulin.

Hence we can conclude from the table attached that After 8 hours of sleep and before eating the hormone that will be secreted is and the cell secreting it is : (A)  I and IV   i.e. Insulin and Beta cells .

A man with type AB blood is married to a woman with type O blood. They have two natural children, and one adopted child. The children's blood types are: A, B, and O. Which child was adopted?

Answers

The adopted is O
AB parent +O parent = A or B or AB baby
A parent+ B parent= AB or B or A baby
AB+B parent=AB or B baby
AB+A parent= AB or A baby
O+O= O baby

The adopted child will have a type O blood group despite the fact that the mother has type O, the father will pass on an A or a B allele to the children. These are dominant alleles.

What are blood groups?

Blood groups are divided into four categories: A, B, AB, and O. The presence or absence of two antigens on the surface of red blood cells determines each one.

A and B are the names of these antigens. Type A blood is defined by the presence of antigen A on red blood cells. Type B blood is defined by the presence of antigen B on red blood cells. You have type AB blood if both antigens (A and B) are present on your red blood cells.

And if neither antigen (A or B) is present on your red blood cells, you have type O blood.

Thus, we can conclude that the adopted child blood group will be O.

The term "gene" has a variety of meanings in biology. The molecular gene is a sequence of nucleotides in DNA that is transcribed to form a functional RNA, whereas the Mendelian gene is the fundamental unit of inheritance.

Protein-coding genes and noncoding genes are the two different categories of molecular genes. While type III genes are involved in cell-to-cell signalling and type II genes are a complicated combination of all three types, type I genes often function as immune response or sensory receptors.

which term is used to describe an animal's ability to survive if the cells are exposed to a hypotonic or hypertonic environment?

Answers

The term osmoregulation is used to describe an animal cell's ability to survive if in a hypotonic or hypertonic environment.

What is a hypotonic environment? A solution whose concentration is less than that of another solution is called as hypotonic solution. If a cell placed in a hypotonic solution, then water enters into the cell by the process of endosmosis and the cell becomes turgid or swollen. What is a hypertonic environment? A solution whose concentration is more than that of the another solution is called as hypertonic solution. If a cell placed in a hypertonic solution, water comes out of the cell by the process of exosmosis and the cell becomes flaccid or shrinks up. What is osmoregulation? It is a process which helps in regulating the osmotic pressure and the fluid-electrolytic balance in a cell.Osmo-receptors can detect changes in the osmotic pressure. Warm-blooded organisms and humans have their osmo-receptors in the hypothalamus. Osmo-regulators are also found in kidney.

Hence, the correct answer is osmoregulation.

14. Write a flow chart for any one type of fermentation, starting from Glucose -------- to
lactic acid or alcohol and CO2.Mention in between steps.

Answers

Answer:

In lactic acid fermentation: Glucose --> pyruvate-->  lactic acid

Explanation:

Some organisms produce their own chemical energy supply, or they may ingest organic substances like glucose and absorb energy. Such species may produce energy provided by producers.

Without the presence of oxygen, they break down chemical energy from glucose by lactic acid fermentation in their cytoplasm.

Within Glycolysis:

In order to break up glucose into 2 molecules of pyruvate, 4 ATP and 2 electrons holding NADH molecules, 2 molecules of ATP are used. Since 2 ATPs are used, this process generates a net 2ATP.

Then...

Pyruvate is then converted to lactic acid, forming 2 NAD+s, which are used as electron carriers.
