How does natural selection lead to increases and decreases of specific traits?

Answers

Answer 1

More individuals with beneficial mutations will survive than those without it, and it will lead to an increase in the expression of those certain traits throughout the population through increases and decreases of specific traits.

Any modification to a species' structure or behavior that makes it more suited to surviving and procreating in its environment is referred to as an adaptation. Random mutations can cause the expression of particular features to become more prominent. Natural selection will result in an increase in the expression of specific features throughout the population since more people with advantageous mutations will survive than those without them.

Physical characteristics of an organism, such as the bill on a bird or the fur on a bear, are examples of structural adaptations. Behavioral adjustments make up the rest. Organisms use behavioral adaptations to help them survive. Bird migration and calls are two examples of behavioral adaptations.

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.

Answers

The answer is the second answer

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.

A parent cell has 28 chromosomes and completes meiosis. How many chromosomes result in each cell produced

Answers

If a parent cell has 28 chromosomes then the number of chromosomes in the daughter cell produced after the cell undergoes meiosis is 14 chromosomes.

Meiosis is a cell division process for gamete production. It helps in the sexual reproduction of eukaryotes. Gametes produced from two parents will unite to form the zygote, which thus contains a combination of unique sets of chromosomes inherited from two parents.

Hence each daughter cell will have half the no of chromosomes as that of their parents. So the number of chromosomes in each of  the daughter cells is 28/2 = 14 chromosomes. In meiosis 1 the number of chromosomes becomes half while in meiosis 2 , it is similar to mitosis, so the number of chromosomes remains the same.

Answers

Since the bacterium expresses the foreign gene from the African clawed frog, therefore, the bacterium is considered as the transgenic organism.  

Gene is the most basic unit of heredity. It is the segment of DNA that encodes for a particular protein. There are various genes present in a single DNA strand. The genes are further composed of alternative forms called the alleles.

Transgenic refers to the phenomenon where DNA segment from an unrelated organism is artificially introduced and expressed in the host's genetic machinery. Such an organism is called the transgenic organism. And the artificially introduced gene is called transgene.

How does smoking weaken damage the respiratory system?

Answers

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.

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

Answers

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.

The cremaster muscle helps maintain testicular temperature. What does the action of this muscle suggest about how it is controlled

Answers

The cremaster muscle is controlled by the sympathetic nervous system.

The sympathetic nervous system is responsible for the "fight or flight" response, and it is activated during times of stress or physical activity. The action of the cremaster muscle, which helps maintain testicular temperature, suggests that it is controlled by the sympathetic nervous system to respond to changes in the body's internal and external environment. Specifically, when the body is under stress, the sympathetic nervous system will cause the cremaster muscle to contract, drawing the testicles closer to the body and increasing their temperature. This is thought to help protect the sperm from damage due to changes in temperature. Conversely, when the body is at rest or in a relaxed state, the cremaster muscle relaxes, allowing the testicles to hang away from the body and decrease in temperature, which is optimal for sperm production.

What are the 4 main points of natural selection?

Answers

The four major principles of natural selection are that populations of living things change over time due to a straightforward mechanism called natural selection.

In fact, it is so straightforward that it can be divided into five simple processes, referred to here as VISTA (variation, inheritance, selection, time, and adaptation). Most attributes are inherited, more offspring are generated than can survive, and offspring with more attractive traits will survive and have more offspring than those with less favorable traits.

These three principles result in natural selection, which is an unavoidable process. More environment-adapted organisms are more likely to survive and pass on the genes that contributed to their success. Over time, species change and diverge as a result of this process.

Which of the following functions occurs in the part of the digestive system indicated by the arrow? dehydration and compaction of indigestible materials add breakdown of swallowed foods O secretion of bile and storage of nutrients O secretion of buffers and digestive enzymes

Answers

The correct option (a) Dehydration and compaction of indigestible materials add breakdown of swallowed foods.

The gastrointestinal tract, as well as the digestive organs, comprise the human digestive system (the tongue, salivary glands, pancreas, liver, and gallbladder). Digestion is the process of breaking down food into smaller and smaller components so that it may be absorbed and digested by the body. The digesting process is divided into three stages: cephalic, stomach, and intestine.

The initial step of digestion, known as the cephalic phase, begins with secretions from stomach glands in reaction to the sight and smell of food. This stage comprises the mechanical breakdown of food by chewing as well as the chemical breakdown by digestive enzymes in the mouth.

What is hypothesis?A hypothesis (plural: hypotheses), in a scientific context, is a testable statement about the relationship between two or more variables or a proposed explanation for some observed phenomenon. In a scientific experiment or study, the hypothesis is a brief summation of the researcher's prediction of the study's findings, which may be supported or not by the outcome. Hypothesis testing is the core of the scientific method.The researcher's prediction is usually referred to as the alternative hypothesis, and any other outcome as the null hypothesis -- basically, the opposite outcome to what is predicted. (However, the terms are reversed if the researchers are predicting no difference or change, hypothesizing, for example, that the incidence of one variable will not increase or decrease in tandem with the other.) The null hypothesis satisfies the requirement for falsifiability: the capacity for a proposition to be proven false, which some schools of thought consider essential to the scientific method.
