During most of the cell cycle, inter-phase, the chromosomes are somewhat less condensed and are not visible as individual objects under the light microscope. However during cell division, mitosis, the chromosomes become highly condensed and are then visible as dark distinct bodies within the nuclei of cells.

What would happen if the Golgi bodies in the cell were destroyed?
The cell would not be able to digest or break down the materials left over from protein creation.
Explanation:
Without a Golgi apparatus, there would be no lysosomes in a cell. Subsequently, the cell would not be able to digest or break down the materials left over from protein creation. This would create a lot of excess junk within the cell. If this happened, the cell wouldn't be able to live for very long.

There are _____ levels of intellectual disabilities on the modern continuum.
A.
five
B.
four
C.
three
D.
two
Answer:
B) Four
Explanation:
There are four levels of intellectual disabilities on the modern continuum. The correct option is B.
What are intellectual disabilities?A person is said to have an intellectual disability when their capacity to learn at a typical rate and function in daily life is restricted. The severity of intellectual disability in children varies widely.
Despite the fact that a precise full-scale IQ test result is no longer necessary for diagnosis, standardised testing is nevertheless used to help make the diagnosis.
A full-scale IQ score of between 70 and 75 denotes a considerable intellectual functioning restriction.
Each person's level of difficulty with learning and processing information, difficulties with abstract cognition, and issues with social interaction are all common aspects of intellectual impairments.
On the contemporary continuum, there are four stages of intellectual disability.
Thus, the correct option is B.

TRUE FALSE: Organisms can CHOOSE to have a mutation
Answer:
False
Explanation:
Organisms themselves cannot choose to have a mutation. However, it can be artificially done in labs.
Organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.
What is the significance of the mutation and its consequences?mutation has many consequences, such as the Mutations can cause developmental disorders such as birth defects, mutations can increase an individual's risk of developing genetic disorders, and they also reduce the genetic diversity of a population. Mutation leads to the loss of function in an essential gene, resulting in a decrease in the organism's fitness in the ecosystem.
Hence, organisms can choose to have a mutation, but this is a false statement because mutation is not voluntary but involuntary and can be caused by many factors, such as environmental factors.

1 In the picture above, do you expect the net flow of
chloride ions to flow in or out of the cell? Explain your
answer
Answer:
It should flow outside.
Explanation:
There are more of the chloride ions on the inside part than on the outside part of the cell so it would go to the outside.
The chlorine molecule will move from inside to outside of the cell.
What is membrane potential?
The molecules move from higher membrane potential to lower membrane potential. Diffusion via a semipermeable membrane leads to osmosis.
The solvent will tend to permeate from the less concentrated to the more concentrated solution if two solutions with varying concentrations are separated by a semipermeable membrane.
The name of this procedure is osmosis. Both processes are examples of passive transport at the cellular level.
Therefore, The chlorine molecule will move from inside to outside of the cell.

In the Calvin cycle the conversion of energy poor carbon dioxide into energy rich glucose
A) atp is used
B) pyruvic acid is produced
C) oxygen is produced
D) nadph is made
Answer:
D)NADPH is made
A)ATP is used
Explanation:
Sorry to ask the two questions, I asked why the two options are in the process:Reduction. In the second stage, ATP and NADPH are used to convert the 3-PGA molecules into three-carbon sugar molecules, glyceraldehyde-3-phosphate ( G3P ). At this stage, it gets its name because NADPH donates, or reduces , electrons to a three-carbon intermediate to form G3P.[Ocultar detalhes]
The reduction stage of the Calvin cycle, which needs ATP and NADPH, converts 3-PGA (produced in the fixation stage) into a three-carbon sugar. This process takes place in two main stages:
Simplified diagram of the reduction step of the Calvin cycle showing the carbon atoms, but not the complete molecular structures. A 3-PGA molecule first receives a second phosphate group from ATP (generating ADP). Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.

Then, the doubly phosphorylated molecule receives electrons from NADPH and is reduced to form glyceraldehyde-3-phosphate. This reaction generates NADP + and also releases an inorganic phosphate.
First, each 3-PGA molecule receives a phosphate group from ATP, becoming a doubly phosphorylated molecule called 1,3-bisphosphoglyceride (and leaving an ADP as a by-product).
Second, 1,3-bisphosphoglycerate molecules are reduced (gain electrons). Each molecule receives two electrons from NADPH and loses one of its phosphate groups, becoming a three-carbon sugar called glyceraldehyde-3-phosphate (G3P) . This step produces NADP^+

The ATP and NADPH used in these steps are products of the photo-dependent reactions (first stage of photosynthesis). That is, the chemical energy of ATP and the reducing potential of NADPH, both produced with the use of light energy, keep the Calvin cycle running. Conversely, the Calvin cycle regenerates ADP and NADP^+

How is the difference in the walls of the atria and ventricle related to the different functions of the atria and ventricle?
Answer:
The atria are thin-walled sacs that receive blood from the body or lungs, while the ventricles have a thick muscular wall because they must pump the blood with greater pressure than the atria.
Explanation:
In the human heart, the atria and ventricles are responsible for handling blood and have different structures and function.
The atria are thin-walled sacs located at the top of the ventricles and their function is to receive the blood that comes from the whole body —right atrium— or from the lungs —left atrium— to pass it to each ventricle through the atrioventricular valves, which does not require much pressure. On the other hand, the walls of the ventricles are made up of a thick layer of muscular tissue, since the pressure with which they must pump the blood -towards the lungs or to the entire organism- is greater than that of the atria.The structure of each chamber of the heart is configured to be able to fulfill the specific function that they possess.

What shift in population growth has occurred by point A?
1 The birth and death rates are equivalent.
2 The rate of emigration equals the death rate.
3 The population sizes of the organism and its predator are equalized.
4 There will be more food available than the populations can consume.
The shift in population growth has occurred by point A is The birth and death rates are equivalent.
How does birth rate and death rate affect population growth?Population alteration is controlled by the balance between birth rates and death rates.
Suppose the birth rate stays constant and the death rate decline, then population numbers will increase.
whereas If the birth rate grow at a faster rate and the death rate stays the constant, then population will also increase.
Thus, option "A' is correct, The birth and death rates are equivalent.
