The circulatory and respiratory systems are involved in respiration. They provide oxygen to the body cells and remove carbon dioxyde. The correct option is A. To remove carbon dioxyde from the body.
Two systems work together when providing oxygen to the body cells and removing carbon dioxide: The circulatory and respiratory systems
• Respiratory systemThis system is in charge of the gasses interchange. It takes oxygen from the air and releases carbon dioxide.
• Circulatory systemThis system is in charge of driving oxygen to the organism's tissues and cells and taking away carbon dioxide from them.
These gases are in the oxygenated and deoxygenated blood, respectively.
The heart bombs blood through arteries, veins, and capillaries to the whole body.
The blood carries oxygen to different tissues.
This oxygen is absorbed in the lungs and proceeds from the air that we breathe. Its final destiny is all the cells in the organisms.
Types of circulation• Lung circulation
1. Moves blood between the heart and the lungs.
2. Deoxygenated blood goes from the heart to the lungs
3. In the lungs, deoxygenated blood releases carbon dioxide and gets oxygenated again.
4. Carbon dioxide is released by exhalation.
5. Blood absorbs oxygen from small air sacs named alveoli.
6. Oxygenated blood returns to the heart.
• Systemic circulation
1. Carries blood between the heart and the rest of the body.
2. Oxygenated blood leaves the heart and moves to all the cells in the body.
3. Deoxygenated blood returns from tissues to the heart.
According to thi framework, the function of the organ system shown in the picture is to remove carbon dioxyde from the body. Option A.

Answers
Answer: c. burning of fossil fuels.
Explanation:
Carbon Dioxide and other greenhouse gases like it are the reason some of the sun's heat is trapped in the atmosphere instead of leaving back into space. Any process which increase the amount of carbon dioxide in the atmosphere therefore can increase global warming.
One of the major human activities that involves releasing carbon dioxide is the burning of fossil fuels. We use fossil fuels for many things including producing electricity and driving. When this happens we release a lot of carbon dioxide into the atmosphere thereby making global warming worse.

Temperature facilitates deciding what can input or depart the cellular and the way properly molecules observed inside the membrane can function. Temperatures that might be too excessive or too low can severely harm and, in the intense temperature ranges, kill the cellular via their impact at the cellular membrane.
Physiologically ordinary intracellular pH is maximum generally among 7.0 and 7.4, even though there may be variability among tissues (e.g., mammalian skeletal muscle has a tendency to have a pHi of 6.8–7.1). There is likewise a pH version throughout special organelles, that can span from round 4.5to 8.0.
Water concentration:
Water molecules flow into and out of the cell at an identical fee, so the length stays constant. then a cell. This method of water attention is better within the cell than outside. Thus, water flows out of them, inflicting them to shrivel or maybe die.
Salt concentration:
Increase of the way of life medium NaCl attention from a hundred and 20 mm to 220 mm ended in a reduced boom fee and a boom in the content material of ribonucleic acid (RNA), protein, and lipide phosphate consistent. Cell quantity becomes likewise increased.

Why is it important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high?
Answers
Answer:
These characteristics of water allows excellent working in the steam engines.
Explanation:
It is very important that the heat capacity, latent heat of fusion and latent heat of vaporization of water are high because due to large heat of vaporization, steam or vapors of water carries a huge amount of thermal energy. This large amount of heat energy is released when the steam condenses due to loss of kinetic energy. This property of water making it an excellent working fluid for heat engines as compared to any other fluid.

b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
Answers
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.

What is the significance of a balanced diet for maintaining a healthy level of biomolecules in our cells and body to function disease-free?
Answers
Answer:
A balanced diet makes our body work in the best possible way. Both the lack of food and the excess of them is detrimental to health, therefore the appropriate amounts must be consumed for each individual. It meets our basic physiological needs and reduces the risk of disease.
Explanation:
Food is the set of processes that allows organisms to use and transform nutrients to stay alive. A balanced diet will largely depend on the human being leading a healthy life. The foods that are consumed each day must have adequate amounts of both the macronutrients (carbohydrates, proteins, lipids), as well as the micronutrients (minerals and vitamins) and water, which are bioavailable that the consumed diet must contain, in order to satisfy the requirements physiological of each individual. In addition to covering individual variability, for some nutrients an additional amount is added to establish a margin of safety. Complying with the appropriate amounts avoids and prevents overweight, obesity, as well as chronic degenerative diseases such as diabetes mellitus, dyslipidemias, cardiovascular diseases, cerebrovascular disease, etc. and in turn helps the person to look and feel better, increasing physical and mental performance. Poor nutrition means neglecting some nutrients or overdoing others. This is the main factor that promotes progressive weight gain and obesity according to experts.

Answers
Answer:
The correct answer is - each macromolecule has its own function and role in the body of an organism.
Explanation:
There are four major macromolecules that are essential for the energy and growth and development of an organism, are Proteins, carbohydrates, fat and nucleic acids. Each macromolecule is essential and found in various food sources so any specific macromolecule can not found in a healthy diet.
Proteins play various roles in the body such as support, building blocks, carriers, enzymes, and hormones.

Genetically modified foods, also known as genetically engineered foods, or bioengineered foods are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
The most common GMO crops include soybean, maize, cotton, canola, and alfalfa. The following GMO crops were also planted in different countries in 2018: papaya, eggplant, potato, apple, safflower, pineapple, and sugarcane.
For centuries, farmers have bred crops for certain desirable traits. Genetically Modified (GM) crops offer improved yields, enhanced nutritional value, longer shelf life, and resistance to drought, frost, or insect pests.
Genetic modification of plants involves adding a specific stretch of DNA into the plant's genome, giving it new or different characteristics. ... The gene of interest is transferred into the bacterium and the bacterial cells then transfer the new DNA to the genome of the plant cells
GMOs have helped farmers reduce their environmental footprint by allowing them to use fewer inputs and enabling a shift to reduced tillage. These practices have led to less time spent on a tractor, less fuel used and fewer emissions.

hich statement is a correct description of the processes of respiration and transpiration in a plant?
Question 6 options:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Transpiration is when the plant pulls water into its roots. Respiration is when the plant breathes.
Transpiration is when the plant grows over time. Respiration is when the plant breaks down the sugar in its roots.
Transpiration is when the plant produces buds. Respiration is when the plant dies.
Answers
Answer:
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.
Explanation:
Transpiration and respiration are both processes carried out by plants. Transpiration is the process by which plants lose water via a structure in their leaves called STOMATA. When plants open their stomata for gaseous exchange i.e. take in CO2 or give out O2, they lose water vapor in the process in a process called TRANSPIRATION.
Contrarily, RESPIRATION is a cellular process in which the cells of a plant breakdown sugar molecules (glucose) in order to release energy (ATP) in the process. Respiration equation is as follows:
C6H12O6 + 6O2 → 6CO2 + 6H2O
Transpiration is when the plant loses water through its leaves. Respiration is when the plant breaks down the sugar in its cells to release energy.

Cell wall
Golgi apparatus
Chloroplast
Cell membrane
Intermediate filaments
Ribosome
Answers
Answer:
Cell wall: A protective layer covering the outside of the cell. They keep the shape of the plant cell, prevent water loss, and provide support.
golgi apparatus: Transports proteins and lipids around the cell. Often it is called the shipping department of the cell.
chloroplast: Chloroplasts store chlorophyll and this is where photosynthesis takes place in the cell.
Cell membrane: A layer that covers the cell, acts as a gate and determines what comes and goes through the cell. It allows good things in, while keeping others out.
Intermediate filaments: Provides support when when the plant cell comes into contact with other cells.
Ribosome: The part of the cell that is responsible for creating proteins.
The cell wall is an extra protective layer around the plasma membrane, and allows for plant protection from bacteria, water etc. The Golgi apparatus is an organelle within plant cells that modifies, packages, and transports proteins and lipids throughout the cell. Chloroplasts are organelles within plant cells that are responsible for photosynthesis. They contain thylakoids and the stroma. The cell membrane (aka plasma membrane) is made up mainly of phospholipids. It is selectively permeable, meaning it only allows certain substances to pass, usually small, non-polar particles. Ribosomes are the sites of protein synthesis, or where proteins are built. Hope that helps!
