The respiratory system works with the ______ system to add oxygen to the blood and remove carbon dioxide from the body. what is it ? circulatory,muscular,digestive, or nervous ?
Answer;
-Circulatory system
The respiratory system works with the circulatory system to add oxygen to the blood and remove carbon dioxide from the body.
Explanation;
-The circulatory system is the body's transport system. It is made up of a group of organs that transport blood throughout the body. The heart pumps the blood and the arteries and veins transport it. Oxygen-rich blood leaves the left side of the heart and enters the biggest artery, called the aorta.
-The circulatory and respiratory systems work together to provide body cells with oxygen which is essential for cellular respiration. This process involves the breaking down of glucose so that energy is released in a form that cells can then use. During cellular respiration, carbon dioxide is produced as a waste product. The carbon dioxide then needs to be removed from the cells or it would cause damage or death to them.
Which of the following describes a population that is distributed evenly across an area A.random B.uniform c.clumped d.crowded
Which part of the cell does this illustration represent?
The right answer is Mitochondria.
Mitochondria are limited by two membranes with very different properties:
* The outer membrane is low in protein and contains a transmembrane protein, porin, which allows the passage of ions and water-soluble metabolites of molar mass <10,000 Da.
* In contrast, the inner membrane is very rich in proteins but it is almost impermeable to ions and water-soluble metabolites. These substances can only cross the membrane using transport membrane proteins (ATP, ADP and Pi are transported by this type of protein) or by more sophisticated mechanisms called shuttle.
* The space between these two membranes is called the intermembrane space.

They indicated ownership of bags of grain or cotton.
C.
Tax officials used them as receipts for payment of taxes.
D.
They served as the centerpiece of ornamental clay platters.
The right option is; C. Tax officials used them as receipts for payment of taxes.
Archaeologists believed that tax officials used signature seals as receipts for payment of taxes.
Signature seals are stamps which creates an impression on a piece of paper such as letters, contracts, official paperwork, important documents or arts. Seals are composed of two elements which are; a die that has an inverted image of the seal, and another die which is usually an ink. Different seals are used for many purposes. Signature seals can be used as company seals, or to seal letters that contains private or confidential information.
What type of vegetation would you expect to find on newly formed volcanic islands?
The type of vegetation that would you expect to find on newly formed volcanic islands is the abundance of lichens.
What do you mean by Vegetation?Vegetation may be defined as a process that significantly involves the collection of plant species and the ground cover they provide. These plants are togetherly found in a particular area or habitat.
Lichen belongs to the family of pioneer species that first colonize in barren soil. There is a lack of nutrients on newly formed volcanic islands still, but lichens are able to adapt themselves by secreting some chemicals in the infertile or barren soil and making it somehow nutrient rich.
Therefore, the type of vegetation that would you expect to find on newly formed volcanic islands is the abundance of lichens.

The reaction involved in cellular respiration is similar to that involved in the burning of fossil fuels. What must be an essential component of fossil fuels?
A) oxygen
B) water
C) carbon
D) carbon dioxide
The correct answer is option C
The reaction of cellular respiration and burning of fossil fuel needs carbon. Fossil fuel are like coal is made up of carbon. Organic compounds are made up of carbon(abundant), hydrogen and oxygen in small amounts.
The cellular respiration is the process by which the body obtains energy in the form of ATP by the breakdown of carbohydrates which is also a carbon compound.
Answer:
The correct answer is option C, Carbon
Explanation:
In cellular respiration, a higher carbon molecule i.e glucose breaks down in the presence of oxygen to produce carbon dioxide, water and energy. The chemical equation for cellular respiration is given below –
C 6 H 12 O 6 + 6 O 2 --> 6 CO 2 + 6 H 2 O + ATP
Like wise, in combustion of any fuel , the higher carbon molecules burn in the presence of oxygen to release gases like carbon dioxide methane etc.
Thus, a fossil fuel must be made up of carbon.

Siberian Huskies have two layers of fur. The outside layer is rough and coarse, while the inner layer is very dense and thick. Which theme of biology describes this phenomenon?
Evolution explains unity and diversity through adaptation.
Structure and function are related in biology.
Organisms must maintain homeostasis.
All of the above are correct.
Answer: All of the above are correct.
Explanation:
The siberian huskies live in a cold environment. This is because of the fact that they are adapted to have a two layered fur so as to maintain their homeostasis and adapt to the cold environment. This is the basis for the evolution of these huskies. Thus it can be said that the structure and function in the biology are related. The two layered fur will help in retaining the heat.

what happens when a magnesium atom loses an electron in its outer energy shell? A. it has an increase in number of neutrons. B. it becomes a negative ion. C. it has an increase in the number of protons. D. it becomes a positive ion.
When a magnesium atom loses an electron from its outer energy shell, it becomes a positive ion. The correct option is D
What is electron ?An electron is a subatomic particle that carries a negative electric charge. It is one of the fundamental particles that make up atoms, along with protons and neutrons.
This is because magnesium has 12 electrons, with 2 in its innermost shell and 8 in its second shell. The outermost shell contains 2 electrons, so when one electron is removed, the atom now has 11 electrons and a net positive charge of +1.
Therefore, the correct answer is D

a dihybrid cross between 2 heterozygous parents produces a phenotypic ratio of?
A dihybrid cross between two heterozygous parents produces a phenotypic ratio of 9:3:3:1, which reflects the independent assortment of genes and dominance of certain traits.
Explanation:A dihybrid cross between two heterozygous parents (e.g., GgYy x GgYy) involves two genes and produces offspring with a combination of traits that follow a phenotypic ratio of 9:3:3:1. This means that in the context of pea plants with two traits such as seed shape and color, 9/16 of the plants would exhibit both dominant traits (round, yellow seeds), 3/16 would exhibit one dominant and one recessive trait (round, green seeds or wrinkled, yellow seeds), and 1/16 would exhibit both recessive traits (wrinkled, green seeds). These proportions can be visualized using a Punnett square and result from the principles of independent assortment and dominance in genetics.
The phrase “opposites attract” can be seen very clearly in A Covalent bonds B Ionic bonds C Electron bonds D Proton bonds...
The right option is; A. covalent bonds
The phrase “opposites attract” can be seen very clearly in covalent bonds.
A covalent bond is a molecular bond that occurs when pairs of electrons are shared between atoms. The bond is caused by the electrostatic attraction of their nuclei for the same electrons. When electrons are shared, it makes each atom to fill up their outer electron shell and gain stability. When two atoms of the same element share electrons through covalent bonding, the electrons are shared equally between the atoms, but if it is shared between atoms of different elements, the electron will be drawn (attracted) more toward the atom that has the higher electronegativity which will cause a polar covalent bond.
Answer:
Ionic bonds
Explanation:
I answered with Covalent bonds and was wrong and checked and it was Ionic bonds.

you suspect that a chemical that you are testing in the lab is strongly acidic . what might be its ph
A chemical that is strongly acidic would likely have a pH close to 1-2. The pH scale, which measures from 0 (most acidic) to 14 (most basic), denotes acids with a pH lower than 7. Strong acids, like stomach acid, significantly change the pH of a solution rapidly due to high hydrogen ion production.
If you suspect that a chemical you are testing in the lab is strongly acidic, its pH would likely be very low. The pH scale is an inverse logarithmic scale ranging from 0 to 14 and measures the acidity or basicity of a solution. Strong acids can have pH values from about 1 to just below 7. However, extremely strong acids can even possess negative pH values. Examples include stomach acid, which has an acidic pH of 1-2, indicating a high level of acidity.
To give you context with examples, consider the following substances:
Human blood, with a pH of 7.4, is slightly basic and is considered neutral.Household ammonia has a pH of 11.0 and is a basic substance.Cherries, with a pH of 3.6, are acidic.If you were testing a chemical with a strongly acidic nature, such as stomach acid, you could expect a pH close to 1-2, comparable to the highly active chemical nature of strong acids.
