Answer:

just go with your instincts

Yeah it's possible. Even though both parents have round jaws... that may be the result of a dominant trait overpowering the recessive trait. As long as both parents have the recessive gene (in other words they're heterozygous traits) then there is a possibility for a child to be born with a square jaw.

So, DNA: contains genetic information that is necessary for biological functioning and reproduction.

More specifically, it contains the genetic instructions through gene encoding that instructs the cell what to do. A specialized complex ribosome interacts with the DNA molecules and "reads" it, changing the genes from the DNA into proteins that the cell as a whole can function upon. It is also crucial to forming a whole cell in offspring, since only the genes from the two parents combined (in humans at least) can produce an offspring with all genes intact. Those who do not have genetic disorders, a famous one being Down Syndrome.

Next, RNA: a molecule necessary for expressing genes and making proteins.

Connecting to the paragraph above for DNA, RNA also assists in the process by reading the ribosome that reads the DNA itself. Complicated, I know. All you have to know, however, is that the RNA, in this case called mRNA since it serves as a messenger, hence, the "m", reads the codons produced by the ribosome when it reads the DNA, and makes proteins according to those codons, and those proteins then scatter all across the cell to execute instructions.

Now, we move onto nitrogen and phosphorous: both are found in amino acids, the building blocks of proteins.

That is actually partially wrong. Amino acids do not contain phosphorous, but do contain nitrogen. Not exactly sure what went wrong on your end there, but nitrogen is a basic building block for amino acids, which are basic building blocks themselves for proteins. To be more clear, amino acids are made of carbon, hydrogen, oxygen and nitrogen atoms. No phosphorus there!

Finally, enzymes: special proteins that accelerate chemical reactions in cells.

This is correct. Enzymes typically lower the activation energy required for reactions to happen. More specifically, enzymes make the reaction molecules more active, hence, lowering the threshold for the amount of energy you have to put in before the molecules start crashing into each other hard enough to have a chemical reaction. Of course, enzymes do not participate in the reaction itself, which makes them incredibly useful for spurring on chemical reactions since they can be used multiple times.

QUESTION: this for the other version.. " Investigate substances containing carbon or oxygen that relate to biological processes. Explain their main function in those processes. "

ANSWER: I chose to investigate four substances: carbon dioxide, ethanol, glucose, and cellulose. According to my research, these are the main functions of these substances in various biological processes:

Carbon dioxide: Carbon dioxide is a product of aerobic respiration. Most living organisms exhale carbon dioxide while plants inhale it in the respiratory process. Carbon dioxide is converted to organic matter in the process of photosynthesis carried out by autotrophs.

Ethanol: The process of fermentation gives rise to ethanol, which is an alcohol. Ethanol is formed through a type of anaerobic respiration, that is, respiration without the use of oxygen.

Glucose: Glucose is a form of carbohydrate. It is nothing but simple sugar that stores energy in plants and animals.

Cellulose: Cellulose is an organic polymer used to make cell walls in plants.

Answer: if your question has to do with homeostasis here you go! i hope this helps:)

In order for a body to work optimally, it must operate in an environment of stability called homeostasis. When the body experiences stress—for example, from exercise or extreme temperatures—it can maintain a stable blood pressure and constant body temperature in part by dialing the heart rate up or down.

The loss of too much blood may lead to circulatory shock, a life-threatening condition in which the circulatory system is unable to maintain blood flow to adequately supply sufficient oxygen and other nutrients to the tissues to maintain cellular metabolism.

The first phase is interphase, during which the nucleus divides and the DNA replicates. The second phase is mitosis, during which the cytoplasm divides. The third phase is cytokinesis, during which the cell divides into two daughter cells.

The cell cycle is the series of events that take place in a cell leading to its division and duplication. It consists of two major phases: interphase and the mitotic phase. The mitotic phase is further divided into two stages: mitosis and cytokinesis.

During interphase, the DNA of the cell is replicated in preparation for cell division. This phase is divided into three subphases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2).

During G1, the cell grows and prepares for DNA synthesis. During the S phase, the DNA is replicated, resulting in two identical sets of chromosomes. Finally, during G2, the cell prepares for mitosis.

After interphase, the cell enters the mitotic phase. During mitosis, the replicated chromosomes condense and line up at the center of the cell. The nucleus then divides into two identical nuclei, each with a complete set of chromosomes.

After mitosis, cytokinesis occurs, which is the process by which the cytoplasm divides, separating the two daughter cells. The cytoplasmic division usually occurs simultaneously with the telophase stage of mitosis, resulting in the formation of two genetically identical daughter cells.

Therefore, interphase is the phase in which DNA replicates, mitosis is the phase in which the nucleus divides, and cytokinesis is the phase in which the cytoplasm divides to form two genetically identical daughter cells.

Answer:

The correct answer is option A ( a potentially fatal buildup of acetoacetate or 3-hydroxybutyrate lowering blood pH.)

Explanation:

Ketoacidosis results in a type of body metabolic state where the urine concentrations are high in ketone bodies, such as acetoacetic acid , 3-hydroxybutyrate. Fatty acids are converted to ketone bodies, resulting in a very high level of ketone bodies which automatically lowers the blood pH.

Ketoacidosis is of different types, Diabetic ketoacidosis, alcoholic ketoacidosis, starvation ketoacidosis. They are all associated with the accumulation of ketone bodies within the bloodstream. The underlying disease  common with ketoacidosis is Diabetes.

Answer:

Fluoride levels in the bone would be higher in individuals with osteosarcomas.

Explanation:

Fluoride levels will be higher in bone of the individuals with osteosarcomas.

Fluoride is a group of compounds which is a combination of fluorine and other elements, these compounds are present in water, plants, rocks, air, and soil.

Some of fluoride compounds are sodium fluoride, stannous fluoride, and fluoride mono-fluorophosphate.

Once fluorides are absorbed inside the body, it travels into the blood through the digestive tract, tend to collect in areas with high calcium like  bones and teeth.

Majorly fluorides are used in drinking water, beverages, food, and  dental products, mostly fluoro-silicic acid, sodium fluorosilicate, and sodium fluoride forms are added to water.

Structural and behavioral adaptations can indeed impact the reproductive success of plants and animals. Adaptations are traits or behaviors that help organisms survive and reproduce in their environment. The statement is true.

Structural adaptations refer to physical features or characteristics that organisms possess. For example, plants may develop specialized structures like flowers, fruits, or seed dispersal mechanisms that enhance their reproductive success. Animals may have specific anatomical features like camouflage, protective shells, or specialized reproductive organs that increase their chances of successful reproduction.

Behavioral adaptations, on the other hand, involve actions or behaviors that organisms exhibit. These behaviors can include courtship rituals, mating displays, migration patterns, or parental care. Such behaviors help attract mates, establish territories, protect offspring, and ensure the successful transfer of genetic material.

Therefore, the statement is true.

Introduction:

Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells also contain the body’s hereditary material and can make copies of themselves. Cells have many parts, each with a different function. Some of these parts, called organelles, are specialized structures that perform certain tasks within the cell.  

Materials:

• Microscope  

• Prepared slide of muscle tissue  

• Prepared slide of some internal organ such as the kidney, liver, or heart

• Prepared slide of erythrocytes, or leukocytes (from blood)

Instructions:

1. Place one of the prepared slides of animal tissue on the stage of the microscope.

2. Focus the microscope on low power. Then change to the high-power objective. Focus on the tissue, and note the cells.

3. On a separate sheet of paper, draw an individual cell that you see in the tissue. Note the shape of the cell and its other distinctive characteristics.

-What do you think the function of this cell might be?

4. Repeat Steps 1 and 2 using the other prepared slides.

5. On a separate sheet of paper, draw individual cells from the other prepared slides examined.

Questions:  

What do you think the functions of the other cells drawn might be?

- (i think this differs on person to person so may need to do it yourself)

If all of the different kinds of cells which you observed had been taken from the same organism or individual, would they have all had the same genetic information?

- Yes, the cells will have the same genetic information. However, the particular combination of genes that are turned on (expressed) or turned off (repressed) dictates cellular morphology (shape) and function. Essentially meaning that though the cells share the same genetic information they do not necessarily share the same functions.  

Consider specialization:  What biological concept or occurrence is demonstrated by the different kinds of cells which were observed?

- Though these cells have the same DNA, they all have different phenotypes. The phenotypes are different because the cells appear different under the microscope. The cells do this by expressing different genes at different rates. For example, the blood cell is expressing the gene to make hemoglobulin while the other cells are probably expressing different genes that allow them to be specialized. Cells differentiate which means that they are becoming more specialized. Epigenetics focuses on how cells become more specialized.  

Why is it important?

- This is important because it allows different parts of the body to carry out their crucial functions necessary for the whole body to run properly.
