primary tissue of tendons and ligaments?
Answer:
fibrous connective tissue
Explanation:
Ligaments and tendons are both made up of fibrous connective tissue, but that’s about where the similarity ends. Ligaments appear as crisscross bands that attach bone to bone and help stabilize joints. For example, the anterior cruciate ligament (ACL) attaches the thighbone to the shinbone, stabilizing the knee joint.

Answer:
The four main categories of large biological molecules present in living systems are proteins, nucleic acids, carbohydrates and lipids.
Explanation:
Biological molecules (bio-molecules) are the building blocks of a the cell.
The four main categories of large biological molecules present in living systems are proteins, nucleic acids, carbohydrates and lipids.
Proteins are large biological molecules composed of smaller molecules called amino acids. Proteins are required for many important functions in the cell such as cell structure, metabolism and growth.
Nucleic acids are important biological molecules that contain the information required for the continuity of life.
Carbohydrates are essentially required for nutrition and growth. They also serve structural purposes as well as many other functions.
Lipids are divided into fats and oils. They serve various functions such as energy stores, and also provide insulation to the living organism.
What is a transform plate boundary? What happens as a result?
Answer:
Two plates sliding past each other forms a transform plate boundary. Natural or human-made structures that cross a transform boundary are offset—split into pieces and carried in opposite directions. Rocks that line the boundary are pulverized as the plates grind along, creating a linear fault valley or undersea canyon.
Answer the following questions.
1) Which of these is not needed by living organisms?
energy
air
water
gravity
space
Answer: Gravity every other option we need for life
Explanation:
Every other option we need for life, otherwise we would not be alive.
The one that is not needed by living organisms is gravity. The correct option is D.
What is gravity?An invisible force that attracts objects to each other Gravity is what keeps you on the ground and causes things to fall.
Universal Gravity is a theory about the natural law of attraction, not a fact. This material should be approached with an open mind, carefully studied, and critically analyzed.
Nonliving things are required for the survival of living things. Living things die in the absence of food, water, and air.
Sunlight, shelter, and soil are also essential for life. Living things in ecosystems get their food from both living and nonliving things.
Every living thing needs food, water, shelter, and a place to live. Its habitat is the location where it obtains these items.
Thus, the correct option is D.

100 points! Complete the simple sugar molecule Glucose. Please fill out the diagram of the molecule and provide the link of the website or picture you got the answer from. H = hydrogen O = oxygen C = carbon
Answer and Explanation:
Glucose is a hexose with six carbon atoms. It is also an aldose, meaning that it has an aldehyde group, CHO in its first carbon atom. The molecule also has hydroxyl groups, OH linked to the carbon atoms.
Its linear structure shows six carbons united in a line. One of its carbon atoms is linked to a carbonate group, H-C=O. The other five carbons are linked to the hydroxyl groups, OH.
In an aqueous solution, the glucose molecule turns to the ringed or cyclic structure, as a result of the reaction among the first carbon and the oxygen of the hydroxyl group linked to the fifth carbon.
You will find the complete glucose molecule in one of the attached files (named glucose), plus the linear and cyclic structure in the other file (named glucose1).

if two different types of particles have the same speed in a medium,why is chromatography process not suitable? write with a reason.
Explanation:
When using chromatography, the 2 solutes in the solvent paper should have different Rf values from the base line to identify them as different compounds.
If they were to have the same speed in the solvent, they would appear as 1 dot instead of 2 separate dots, which is a false reading.

Which of the following best describes a molecule?
Answer: Heres my Answer
Explanation: A molecule is defined as two or more atoms of the same element different element that are bound together. A molecule may be homonuclear, which means, it consists of atoms of one chemical element, as with oxygen (O2); or it may be heteronuclear, a chemical compound composed of more than one element, as with water (H2O).
The question is incomplete, the complete question is given below:
Which of the following best describes a molecule?
a unit made of different kinds of elements
a unit made of only one kind of element
a unit made of two or more atoms
a unit made of a single atom
Of the mentioned options, the statement that best describes a molecule is that it is a unit made of two or more atoms.
What is a molecule?It is the smallest particle in a chemical compound or element, which possesses similar properties with that of the compound or element. The molecules are formed of atoms, which are held together with the help of chemical bonds.
These bonds develop as an outcome of the exchange or sharing of electrons between the atoms. The atoms of elements bond easily with other atoms to produce molecules. The molecules can differ largely in complexity and size.
Thus, the correct statement is that it is a unit made of two or more atoms.

Why is the notion of a "missing link" between modern apes and humans inaccurate to scientists?
Group of answer choices
Humans evolved from a common ancestor shared with modern apes, not from modern apes themselves.
None of these is correct.
Humans do not share a common ancestor with modern apes.
Humans arose suddenly from the modern ape lineage due to a single Hox mutation, so there are no intermediates.
Answer:
after reading a bunch, i think its "Humans evolved from a common ancestor shared with modern apes, not from modern apes themselves." so sorry if it's wong! hope it helps <3
Scientists disagree with the idea that there is a "missing link" between humans and modern apes because we did not diverge from modern apes, but rather from a common ancestor with them. Therefore, the correct option is A.
What is the missing link between humans and modern apes?The concept of the "missing link" is no longer considered true or valid by scientists. There is no specific "missing link" species that clearly links contemporary humans with contemporary apes, despite the fact that both modern humans and extant apes descended from a common parent species, which is now extinct.
Instead, the fossil record suggests that various hominin species were present during human evolution, demonstrating a slow but steady evolution of human-like traits. This indicates that a separate animal that went extinct was the common ancestor of modern humans and apes. Because evolution is a gradual change over time with many intermediate forms rather than the instantaneous emergence of a new species, there is no missing link.
Therefore, the correct option is A.

What property of a water molecule allows hydrogen bonds to form among adjacent molecules? PLEASE HELP!!
A. the strong covalent bonds that hold the oxygen atom to each hydrogen atom
B. the ionic bonds that form after the molecule separates into a hydroxide ion (OH–) and hydrogen ion (H+).
C. the small size of the two hydrogen atoms compared to the oxygen atom.
D. the polarity of the molecule, which involves a slightly negative oxygen atom and slightly positive hydrogen atoms
Answer:
D
Explanation:
The water molecule is polar because the oxygen atom is more electronegative than hydrogen causing the electrons from the hydrogens to gravitate closer to the oxygen atom. The molecule is like a magnet; the negative oxygen end will want to stick to the positive hydrogen end of another molecule. Hope this helps
The property of a water molecule that allows hydrogen bonds to form among adjacent molecules is as follows:
The polarity of the molecule involves a slightly negative oxygen atom and slightly positive hydrogen atoms.Thus, the correct option is D.
What is the nature of a water molecule?The nature of a water molecule is polar. This polarity of a water molecule attracts other polar molecules through hydrogen bonding.
The partial positive charge on the hydrogen atom attracts the partial negative charge of an oxygen atom and allows them to form adjacent molecules among them with the help of hydrogen bonding.
Therefore, the correct option for this question is D.
