Answer:
Why do cells die? ... When cells are not needed, such as during certain stages of development. To create a structure in the body, for example, the outer layer of the skin is made of dead cells. To remove excess cells, such as white blood cells after an infection has been cleared.
Cells need to die bcuz a cell has only a limited amount of energy to do its function so it will not work aftr it has no energy. thus cells need to die.

Which of the following is NOT an example of homeostasis?
As humans age, they become more susceptible to disease and cancer.
During rigorous exercise the heart rate increases to deliver more blood to the cells.
When blood glucose is high, the hormone insulin reduces blood glucose.
When body temperature rises, nerve impulses cause sweat glands to release more sweat.
As humans age, they become more susceptible to disease and cancer.
The statement "As humans age, they become more susceptible to disease and cancer" is not an example of homeostasis. Homeostasis refers to the ability of an organism or system to maintain a stable internal environment despite external changes. It involves the regulation and balance of various physiological processes.
The other options provided in the question are examples of homeostasis:
During rigorous exercise, the heart rate increases to deliver more blood to the cells. This is a mechanism by which the body maintains an adequate supply of oxygen and nutrients to the working muscles during increased physical activity.When blood glucose is high, the hormone insulin reduces blood glucose. This is an example of the body's regulation of blood sugar levels to maintain them within a specific range.When body temperature rises, nerve impulses cause sweat glands to release more sweat. This is a response that helps regulate body temperature by cooling the body through evaporation of sweat.In contrast, the statement about aging and increased susceptibility to disease and cancer does not describe a mechanism of maintaining internal stability or balance. Aging is a natural process that is associated with various changes in the body, including a decline in certain physiological functions and an increased risk of developing diseases. It does not directly relate to the concept of homeostasis.

8. Last July, the body of a 16 year old male was found in his car. The body exhibited rigor in the legs, but no rigor in the upper torso. The ambient temperature inside the car registered 102°F. Explain the approximate TOD for this situation.
In this situation, the time of death (TOD) can be estimated by examining the evidence of the body's condition. Rigor mortis, the stiffening of muscles after death, is one of the most reliable indicators of the approximate TOD. The fact that the body of the 16 year old male exhibited rigor in the legs, but not in the upper torso, implies that the body had been in the car for a period of time during which it could have been affected by the ambient temperature.
Rigor mortis usually sets in 2-6 hours after death, and its effects can be seen in the body's muscles for up to 12 hours. As the ambient temperature in the car was 102°F, the body's muscles would have stiffened due to the heat, leading to an accelerated onset of rigor mortis. This means that the TOD for this situation is likely to have been within 2-6 hours of the body being discovered, assuming that the ambient temperature had been stable for the duration of the body being in the car.

How does smoking weaken damage the respiratory system?
The smoking or act of inhaling smoke can damage the respiratory system by reducing the surface area for the exchange of the gases and can lead to cancer as well.
Smoking can cause lung disease by damaging your airways and the small air sacs (alveoli) found in your lungs. It can also cause irritation of the trachea (windpipe) and larynx (voice box). Inhaled tobacco smoke moves from the mouth through the upper airway, ultimately reaching the alveoli.
As the smoke moves more deeply into the respiratory tract, it can cause inflammation and damage to the cilia, tiny hairs that play an essential role in the function of the respiratory system. Smoking can also increase the production of phlegm and mucus, leading to an increased risk of respiratory infections. It can also damage the cilia that help to clear unwanted particles from our lungs over time. Cigarette smoke can also contain high levels of carcinogens, which can lead to lung cancer.

What are the light reactions of plants and in what organelle do they occur?
The light reactions of plants are a series of photochemical reactions that occur in the chloroplasts of plant cells. These reactions convert light energy into chemical energy in the form of ATP and NADPH.
The light reactions are divided into two stages: the light-dependent reactions and the light-independent reactions. The light-dependent reactions take place in the thylakoid membrane and involve the chloroplasts absorption of light energy by pigments, the transfer of electrons through a series of electron carriers, and the production of ATP and NADPH. The independent light reactions, also known as the Calvin cycle, take place in the stroma of chloroplasts and use the ATP and NADPH produced in the light-dependent reactions to fix carbon dioxide and create glucose and other sugars.

What offspring would you predict from a black female cat and an orange male cat?
Black females and orange males also give birth to calico cats. Usually, male kittens only inherit the male's coat color. The Y chromosome determines the sex of males, but has nothing to do with coat color.
Calico cats are domestic cats of all breeds with tricolor coats. Calico cats are most commonly thought of as being 25% to 75% white with large orange and black spots, but they can also include other colors in their patterns. A variation of off-white and gray patches called muted calico sometimes occurs.
The dominant O allele encodes an orange tone, while the recessive O allele encodes non-orange pigmentation (black or brown).

There are two types of blood vessels that connect to capillaries: venules and arterioles. Based on their names, what can you guess their role is in carrying blood
The vasculature is a network of blood arteries that connects the heart to all of the body's organs and tissues. Arteries and arterioles transport oxygen-rich blood and nutrients from the heart to the organs and tissues, while veins and venules return deoxygenated blood to the heart.
Blood vessels are circulatory system components that convey blood throughout the human body. These veins carry blood cells, nutrients, and oxygen to the body's tissues. They also remove trash and carbon dioxide from tissues. All of the body's tissues rely on the functioning of blood arteries to support life.
There are five types of blood vessels: arteries, which take blood out from the heart; arterioles; capillaries, which exchange water and chemicals between the blood and the tissues; venules; and veins, which bring blood back towards the heart from the capillaries.

Explanation:
So if pendulous ear lobes are (E) and adherrent ear lobes are (e)
Its important to regonize that a man who has pendulous ear lobes whose mother had adherrent ear lobes should be written as (Ee) seeing as how the pendulous ear lobes are dominant over adherrent ear lobes
also, recognize that while using a punnet square you have a set of two alleles
Note: The husband is Heterozygous
The Husbands: (Ee) pendulous ear lobes
The Wifes: (ee) adherrent ear lobes
Heterozygous just means they can either pass on the pendulous ear lobes or adherrent ear lobes so their alleles look like (Ee)
you can begin the problem by using a punnet square:
