What are the two great controlling systems of the body?

Hello there!

Your answer would be lung cancer, chronic bronchitis, emphysema and asthma.

Years of smoking and exposure to air pollutants can contribute to the incidence of lung cancer, chronic bronchitis, emphysema and asthma.

Lung cancer is one of the factors that is caused by smoking and air pollutants. This happens when too much lung cells are being produced in the lungs at once, which causes cancer cells to grow, this would form a tumor in the lung. There are many treatments that could be taken to remove this tumor. This is one of the things that are caused by smoking and air pollutants.

Chronic Bronchitis is another factor that is caused by smoking and air pollutants. This also involves the lungs. Chronic Bronchitis is a disease in the lungs that caused inflammation in them, which is very dangerous to the human body. Growth of mucus, coughing, and etc are symptoms of this. This is another factor that is caused by smoking and air pollutants.

Emphysema is another factor that is caused by smoking and air pollutants. This is a disease that causes the alveoli (a balloon shaped pass way in the raspatory system) to over swell. This mostly causes a shortness of breath to a person. This is another factor that is caused by smoking and air pollutants.

Asthma is another factor that is caused by smoking and air pollutants. This condition is very common to people who have smoked, been around smoke, or has been around places whose air is very polluted. This conditions causes the airways to clog up, which makes it hard to breathe. This is another factor that is caused by smoking and air pollutants.

Your chosen answer is correct. The death rate (the red doted line) is higher than the birthrate (blue line)

B.) is incorrect because it is not true that the population is decreasing as shown the line is going up not down.

C.) is wrong because there is a competition between rates

D.) is incorrect because has not yet reached the carrying capacity.

I hope my answers are helpful!

Answer:

There is no competition for resources.

Explanation:

Answer:

The correct answer is option C. "Respect of the human rights".

Explanation:

Ethics refers to a series of moral principles that a person must follow  to conduct and behave properly. Ethical values are closely related with human rights, because human behavior should always look to respect the liberty, autonomy, privacy, informed consent and equality of people. This is the case for anthropologist’s following a code of ethics, at which scholar value must not surpass the respect of the human rights in any case.

The core principle is respect for human rights (C), foundational for ethical research conduct in anthropology.

According to the anthropologist’s code of ethics, the highest value that scholarly research cannot surpass is the respect for human rights (C). Anthropologists are committed to upholding the dignity, autonomy, and well-being of individuals and communities they study. This ethical principle is foundational and guides anthropological research and practice across diverse settings and contexts.

Respect for human rights encompasses various aspects, including but not limited to:

1. Informed Consent: Anthropologists prioritize obtaining informed consent from individuals and communities participating in research. This involves ensuring that participants understand the purpose, risks, and benefits of the research and voluntarily agree to participate without coercion or manipulation.

2. Confidentiality and Privacy: Anthropologists safeguard the confidentiality and privacy of research participants by protecting sensitive information and ensuring that data are anonymized or de-identified when necessary. This helps prevent harm or stigmatization to individuals or communities involved in the research.

3. Avoidance of Harm: Anthropologists strive to minimize potential harm to individuals and communities resulting from research activities. This includes avoiding physical, emotional, or psychological harm and taking measures to mitigate any negative consequences of the research.

4. Cultural Sensitivity and Respect: Anthropologists recognize and respect the diversity of cultures, beliefs, and practices encountered in their research. They strive to engage with communities in a culturally sensitive and respectful manner, acknowledging their perspectives, values, and rights.

In contrast, factors such as hospital permissions (A), government involvement (B), and climatic conditions (D) are important considerations in research planning and implementation but do not supersede the fundamental ethical imperative of respecting human rights. While adherence to legal requirements, institutional policies, and environmental factors is essential, these should be balanced with ethical considerations and the overarching commitment to the well-being and rights of research participants. Therefore, the core principle of respecting human rights stands as paramount in the anthropologist’s code of ethics.

The cell in prophase I of meiosis has four times as much DNA as each daughter cell following cytokinesis of meiosis II, due to the halving of DNA content during meiosis.

A cell in prophase I of meiosis has four times as much DNA as each of the daughter cells following cytokinesis of meiosis II. This is because during prophase I, the cell has undergone DNA replication and thus has double the amount of DNA. After cytokinesis of meiosis II, we have four daughter cells, each having half the amount of DNA as the cell in prophase I. Think of it this way, during meiosis I and II, the DNA content is successively halved in each daughter cell. Hence, in comparison to the cell in prophase I, each of the four daughter cells at the end of meiosis II has a quarter of the DNA.

Answer:

many anterior pituitary hormones regulate other endocrine glands whereas posterior pituitary hormones regulate nonendocrine tissues

Explanation:

Anterior pituitary or adenohypophysis is the anterior lobe of the pituitary gland. Secretion of endocrine cells of the anterior pituitary is controlled by regulatory hormones released by hypothalamus. The hypothalamic releasing hormones bind to anterior pituitary endocrine cells, upregulating or downregulating their release of hormones. Anterior pituitary hormones stimulate endocrine glands: FSH and LH (ovaries and testes), TSH (thyroid), and ACTH (adrenal cortex).

Posterior pituitary or neurohypophysis is the posterior lobe of the pituitary gland. It  is not glandular it is just a collection of axonal projections from the hypothalamus. Posterior pituitary hormones regulate nonendocrine tissues: ADH-vasopressin (kidney tubules) and oxytocin (mammary glands, uterine tissues, brain).

The answer is A. They are all acidic

The correct answer is: The cascade serves to amplify the signal, so one activated receptor can have a significant response

The signal transduction process is represented by series of molecular events that end up with cellular response (change of behavior or characteristic).  

Component of a signaling pathway (based on their role) are:

• Ligands or first messengers

• receptors or the signal transducers

• primary effectors

• second messengers

• secondary effectors…

Signal transduction is part of almost all type of processes in the cell such as cell growth control, proliferation, metabolism etc.

The signaling cascade serves to amplify the signal and impacts multiple downstream components, allowing one activated receptor to stimulate a significant cellular response. The phosphorylation of proteins contributes to shaping this response. The termination of signal response, notably through de phosphorylation is vital to control cell behavior.

During the process of signal transduction, a signaling pathway or cascade is often initiated upon the binding of a ligand to a cell-surface receptor. This chain of events facilitates interactions among second messengers, enzymes, and activated proteins, triggering a response in the cell's environment. A significant part of this cascade is the phosphorylation of molecules by enzymes known as kinases, which alter the shape of proteins and hence, their activity.

Activation of an intracellular component of the receptor often amplifies the signal, with a single activated receptor influencing multiple downstream components of the signaling pathway. The cascading mechanism serves to significantly amplify the signal, allowing one activated receptor to have a prolific cellular response. This amplification is beneficial in cases where the hormonal signal is of a very low concentration.

The effect of cell signaling can be terminated through the degradation of signaling molecules or de phosphorylation of phosphorylated intermediates in the pathway. This termination is essential to ensure the appropriateness of signal response.

The correct answer is: A checkpoint will be activated if the spindle does not attach to a kinetochore.

Prokaryotes, do not undergo mitosis (like eukaryotes) and therefore have no need for a mitotic spindle. Prokaryotes also don’ t have checkpoints foor the regulation of cell division.

Normal eukaryotic cells (unlike cancer cells), move through the cell cycle in a regulated way in order to make sure that cells don't divide under conditions that are unfavorable for them. Information about their own internal state (nutrients, signal molecules, DNA integrity) is signal to go or not to go through the cell division. Because of that there are few checkpoints in the cell cycle at which the cell examines the signals and makes a “decision”. The major checkpoints are:

• The G1- the first point at which it must choose, once it passes the G1 checkpoint the cell enters S phase

• The G2-the cell checks DNA integrity and checks if replication is done well.

• The spindle checkpoint-at the transition from metaphase to anaphase.

The correct answer choice for the problem is A checkpoint will be activated if the spindle is not attached to the kinetochore.

Cell division is a process in which stem cells divide or divide themselves into 2 or more daughter cells. Cell division is a part of our body. We grow because the cells in our body divide.

In the cell cycle, there are two stages, namely interphase, and M-Phase. The interface is the stage where cells do not divide. This phase lasts for 15 hours and there are 3 stages, namely G1 Phase (duplicate cell organelle phase), S-Phase (DNA replication phase), and G2 Phase (phase of cell growth and protein synthesis). It is in the M-Phase stage that the cell begins to divide. This lap only lasts 2 hours and consists of the karyokinesis and cytokinesis processes. Kariokinesis is the stage where the process of cell nucleus division through the ProMAT stage, while cytokinesis is the stage of cytoplasmic division. Cell division is divided into 2 types according to the type of cell dividing, namely division in prokaryotic cells and eukaryotic cells.

1. Cleavage in Prokaryotic Cells

Cleavage in prokaryotic cells is known as binary division, which means this division takes place simply and spontaneously. This cleavage process is also known as the amitotic cleavage process. Amitosis means division that does not involve chromosomes. Binary division can be found in bacterial cells, cell growth processes, duplication of genetic material, chromosome division, and cytoplasmic division.

In binary fission, the chromosomes are duplicated and will stick to the plasma membrane. Then there will be growing between the two attachment sites of the chromosome. This is to do a core separation. Cytokinesis and cell wall formation are then formed so that 2 daughter cells are formed.

2. Eukaryotic Cell Cleavage

Cell division in eukaryotic cells is divided into meiosis and mitosis.

Mitosis

Mitosis division is a division that produces daughter cells that can divide again. The mitotic division produces two daughter cells that are identical to the parent.

Meiosis

The meiotic division is a division that produces gametes. This gamete cannot divide again until fertilization.

When neurons are not producing electrical signals we say that they are at resting phase: voltage across their membrane is called the resting membrane potential, or the resting potential.

This potential is determined by the concentration of ions (Na, K) across the membrane and by membrane permeability to each type of ion. While the ions move through channels down their gradients they lead to a separation of charge and that is what creates the resting potential.

The membrane of the neuron is much more permeable for K ions so the resting potential is close to the equilibrium potential of K+.

Answer:

Explanation:

This is the function of the primer and polymerase enzyme. The plasma membrane is the outermost boundary of the cell. It is selectively allows material in and out of the cell. It has channels through which these materials pass through. If these materials are too large, they are taken in and out through endocytosis and exocytosis respectively.

The answer is A. Left atrium

Oxygenated blood that returns from the lungs enters the left atrium of the heart. From the left atrium, it moves to the left ventricle, which pumps it into the systemic circuit, distributing oxygen and nutrients to the rest of the body.

The blood circulation in our body is a dual system consisting of the pulmonary circuit and the systemic circuit. In the pulmonary circuit, blood flows from the right atrium to the right ventricle, from where it is pumped to the lungs. Here, gas exchange takes place in the pulmonary capillaries, enriching the blood with oxygen and removing carbon dioxide. This oxygenated blood then returns from the lungs and enters the left atrium of the heart. It passes through the left atrium into the left ventricle, which pumps it into the systemic circuit - distributing oxygen and nutrients to the body cells. Therefore, the specific answer to your question is A. Left atrium.

Answer:

ATOM produces all the of the heavy elements required for life.

Explanation:

Atom is the smallest particles of an element, which can exist separately. Atom of the same element combine together to form molecules while atoms of different elements combine together to form compounds.

All the elements that exist in the world today are made up of atoms, which are combine in different ways to form different types of substances. Thus, atom is the basic unit of all elements.

Heavy elements required for life are produced through a process called nucleosynthesis in massive red giant stars. When these stars exhaust their fuel and explode in a supernova, elements heavier than iron are synthesized. These elements are later ejected into space, contributing to the formation of new stars and planets.

The heavy elements required for life, otherwise known as the elements heavier than iron, are produced through a process called nucleosynthesis. This process occurs in the cores of massive red giant stars, which build up the elements via nuclear pathways. However, when these massive stars exhaust their nuclear fuel, they typically explode in a violent event known as a supernova. In the dramatic intensity of such explosions, elements heavier than iron can be synthesized. After these events, the heavier elements are ejected into interstellar space, where they can contribute to the formation of new stars. Over time, the proportion of these heavy elements in the 'raw material' for new stars and planets increases, which is why Earth, rich in heavy elements, was only possible after generations of stars had completed their lifecycles.
