Answer:

Answer

Explanation:

All living things are composed of cells.

Cells are the basic units of structure and function for living things.

All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.

The three basic parts of the cell theory are:

All living things are made of cells.

Cells come from preexisting cells.

All cells have the same basic parts.

Cells are the basic unit of life. All living things, from the smallest bacteria to the largest redwood tree, are made up of cells.

Cells are not created spontaneously. All cells come from the division of preexisting cells.

Despite their great diversity, all cells have the same basic parts, including a plasma membrane, cytoplasm, and DNA.

The cell theory was first proposed by Matthias Schleiden and Theodor Schwann in the 1830s. It has since been supported by a vast body of evidence from cell biology. The cell theory is one of the most important and fundamental concepts in biology.

Answer:

All of the above are correct

Answer:

The correct answer is urine with a lower concentration of sodium ions.

Explanation:

A hormone produced in the cortex or the outer section of the adrenal glands, which are located above the kidneys is known as aldosterone. The hormone plays an essential function in regulating the blood pressure primarily by functioning on the organs like colon and kidney to enhance the reabsorption of sodium or salt into the bloodstream and to enhance the concentration of potassium excreted in the urine.  

Along with sodium, the hormone also works to reabsorb more concentration of water, which further increases the volume of blood and thus the blood pressure. Therefore, with the increase in the levels of aldosterone, the kidneys generate urine with a lower concentration of sodium ions.  

In response to increased levels of aldosterone, the kidneys produce urine with a higher concentration of sodium ions. Therefore, option B is correct.

Aldosterone is a hormone produced by the adrenal glands, specifically in the zona glomerulosa of the adrenal cortex. It plays a crucial role in regulating sodium and potassium levels in the body.

When aldosterone levels increase, such as in response to low blood sodium levels or stimulation by the hormone angiotensin II. Then, it acts on the cells of the distal convoluted tubules and collecting ducts in the kidneys.

Answer:

positive feedback, because the response intensifies the original stimulus

Explanation:

The release of it is increasing contractions making it positive

The hormone oxytocin is released to increase contractions during childbirth, and the pathway is activated with pressure from the baby's head against the opening of the uterus, so it is a positive feedback because the response intensifies the original stimulus that is present in the third option.

Oxytocin, a hormone that plays an important role in the process of childbirth, is produced in the posterior pituitary during labor, and oxytocin is responsible for stimulating contractions of the uterus, which help to push the baby through the wall of the uterus. Oxytocin makes the bond between a mother and her newborn baby, as it is released in large amounts during childbirth and breastfeeding and helps to create a strong emotional bond.

Hence, the hormone oxytocin is released to increase contractions during childbirth, and the pathway is activated with pressure from the baby's head against the opening of the uterus, so it is a positive feedback because the response intensifies the original stimulus that is present in the third option.

Explanation:

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste.

Answer:

Taste receptors.

Explanation:

When activated, the receptor most likely prompting the production of saliva is the taste receptor. When food enters the mouth, the salivary glands produce the saliva upon the sensation of taste. The secretion of saliva (salivation) is mediated by parasympathetic stimulation; acetylcholine is the active neurotransmitter and binds to muscarinic receptors in the glands, leading to increased salivation.

Answer:

The functional groups determine the shapes of macromolecules and this in turn determines their functions.

Functional groups affect the bonds that hold a macromolecule together. For example, the ring forms of glucose in starch and cellulose have different configurations. As a result, cellulose and starch serve different purposes.  

Functional groups also affect the polarity of the bonds. Lipids consist of hydrophilic heads (red) and hydrophobic tails (black and white). This characteristic of lipids allows them to form bilayers, which serve as membranes of cells.  

Proteins have complex structures caused by interactions between the functional groups. A change of a single amino acid can make a major change in the function of a protein.

operation of SODIUM-POTASSIUM PUMP moves sodium ions out of the cell and potassium ions into the cell. The correct option is D.

When a cell membrane moves molecules or ions against a concentration gradient or against an electrical or pressure gradient, the process is called ACTIVE TRANSPORT. Different substances that are actively transported include:

--> sodium ions,

--> potassium ions,

--> calcium ions and

--> some amino acids.

There are two types of active transport which are divided according to the energy that is used to cause the transport. They include:

--> primary and

--> secondary active transport.

PRIMARY ACTIVE TRANSPORT

A typical example is the SODIUM-POTASSIUM PUMP( Na+ - k+). This is a transport process that pumps sodium ions outward through the cell membrane of all cells and at the same time pumps potassium ions from the outside to the inside. This pump helps to:

--> maintain the sodium and potassium concentration differences across the cell membrane

--> establish a negative electrical voltage inside the cells.

The mechanism or OPERATION of the pump involves the following steps:

--> two potassium ions bind on the outside of the carrier protein and three sodium ions bind on the inside,

--> ATpase of the carrier protein cleaves one molecule of ATP, splitting it to Adenosine diphosphate (ADP) and liberating a high-energy phosphate bond of energy.

--> this liberated energy then causes a chemical and conformational change in the carrier protein,

-->this leads to the extruding of three sodium ions (3Na+) to the outside and two potassium ions (2K+) to the inside.

Therefore in the operation of SODIUM-POTASSIUM PUMP moves sodium ions out of the cell and potassium ions into the cell. The correct option is D.

Answer:

The adenosine triphosphate (ATP) molecule

Explanation:

The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.

Answer:

Because these circles have three factors that are directly interconnected.

Explanation:

As you know, communication is one of the primary factors for the creation and maintenance of societies. Societies grow and develop with communication as a starting point and a link between people and the actions that a society lives.

Science, in turn, is also directly influential in the creation and development of society, since it is a transforming factor that shapes society through its constant evolution.

As science evolves, society changes and communication must accompany these changes, so that both society and science continue to exist.

For this reason, we can say that the circle of communication results is linked to the circle called science and society, because these factors are directly interconnected.

Answer:

C. The population moves onto a large, raised, flat area called a plateau for protection from predator.

Explanation:

The plateau phase of population growth indicates that the population has stopped growing as the environment has reached its carrying capacity.

The population after going through different phases eventually reaches the plateau phase where the growth of the population stops or become constant. This is the outcome of the natality rate becoming equivalent to the mortality rate.

This occurs as the resources in the environment become less or scarce as well as there is an elevation in predators and parasites. These are considered as limiting factors to the growth of population. This makes the population number relatively stable. With the limitation in the resources it can be said that the environment has attained its carrying capacity.

Thus, the correct statement is option D.
