Answer 2

Mercury has greater cohesion than adhesion.

What is adhesion?

The attraction between two distinct phases is known as adhesion. Adhesion cannot be explained by a single theory, however it is frequently split into two categories: mechanical interlocking and physical and chemical bonding. Adhesion often results from a mixture of the several mechanisms described below.

When two dissimilar phases only attach to one another mechanically, mechanical interlocking occurs. Typically, for the other material to penetrate, the surface needs to be a little bit rough. adhesion processes

For instance, a low viscosity glue that easily penetrates surface pores and fissures. After the adhesive has dried, this causes mechanical anchoring between the two components.

Therefore, Mercury has greater cohesion than adhesion.

Lipids commonly contain fatty acids. What are the two parts of a fatty acid? Check the correct answers below.

Answers

Answer:

Hydrophillic head and a hydrophobic tail

Explanation:

Every fatty acid is composed of long chain of hydrocarbon tail. This hydrocarbon tail is nonpolar and insoluble in water. Hence this tail is labeled 'hydrophobic'.

However, the head of the fatty acid contains polar COOH group which is capable of interacting with water, hence the head is hydrophillic.

Hence, a fatty acid is composed of a hydrophillic head and a hydrophobic tail.

A major disturbance that almost caused a total collapse, but that the ecosystem was able to recover from eventually.

Answers

The provided question is incomplete, the correct question is attached with the answer:

Answer:

The correct answer is - the grasses which is diseased.

Explanation:

In the event that the grasses were diseased, the environment will recoup itself from this sort of disturbance. On the off chance that the number of inhabitants in snakes and hawks of prey increments so the biological system will recoup itself from this disturbance since snakes are the food of hawks.

So, if the number of inhabitants in snakes increments so more food is accessible for birds of prey as snakes and that is the reason populace of birds of prey likewise increments and the number of inhabitants in snakes is controlled.

An ecosystem is a system where an organism lives collectively and socialise with their surroundings. A robust ecosystem is necessary to keep the control nutrient cycle and food cycle.

A major disturbance from which the ecosystem overcame was when both the grasses and snakes got infected. The explanation for this is:

Increasing the number of snakes affected the size of the grass and decreased the number of rabbits as they were getting eaten by the snakes and hawks.

Increasing the number of snakes also increased the number of their prey hawks.

Increased hawks population controls the population of snakes and in this way, the biological food cycle will be maintained.

Therefore, disease in grasses and snakes caused a major disturbance that almost caused a total collapse, but the ecosystem was able to recover.

What is the density of a 700 kg object with a volume of 649 m3? (Density: D = D = m over v.) 0.927 kg/m3 .4543 kg/m3 1.079 kg/m3 4.543 kg/m3

Answers

Answer:

0.927 kg/m3

Explanation:

The density of a 700 kg object with a volume of 649 m30 is 927 kg/m3. Thus, option A is correct.

This problem is solved using density  = mass /volume formula

mass= 700 kg

volume= 649 m³

density is therefore =  700 kg / 649 m³  = 1.079 kg/m³

What is density?

Density has been calculated by dividing an object’s mass by its volume. The density of the water is generally  1,000 kg/m3 at 4°C. The unit of density has been kg/m3 (kilogram per cubic meter). The SI unit of density is kg/m3.

Density will be a measure of mass per unit volume. It is an intensive property, meaning that its value does not change depending on the size of the object.  In physics, density has been defined as the ratio of the mass of the object to its volume. It has been often defined as mass per unit volume.

In chemistry, density has been defined as the measure of the amount of mass per unit volume of a substance. It has an intensive physical property, meaning that its value does not change depending on the size of the object.

Therefore, The density of a 700 kg object with a volume of 649 m30 is 927 kg/m3. Thus, option A is correct.

This problem is solved using density  = mass /volume formula

mass= 700 kg

volume= 649 m³

density is therefore =  700 kg / 649 m³  = 1.079 kg/m³

Explanation:

Cell Analogy Story

A cell can be compared to a business. The Nucleus controls all cellular functions like a Chief Executive Officer that controls all of the operations and decisions of the business. Within the business there is the cytoplasm. The Cytoplasm in a cell, harbors cell organelles and provides structure. This compares to the factory work space that contains all the working bio-machinery and the nutrients, like the raw materials, for the cellular processes. The Cytoskeleton for a cell is what provides the shape and structure to the cell. This is compared to the architecture structure of a factory. It helps to support and strengthen the structure of the building. The Endoplasmic Reticulum of a cell is the site for protein synthesis, the vesicle packaging and transport. This is compared to an assembly line of the business. This is the main work space for production of the important cell components, for example the proteins. The Golgi Apparatus of the cell is the packaging of molecules into the transport vesicles. This is compared to the packaging department of a business. The packing department is the department that packages the goods that have been prepared. The Lysosomes of the cell is actually the membrane-bound cell organelle. It contains the digestive enzymes that break down the excess or the otherwise known worn-out parts of the cell. If the cell is considered damaged beyond repair it will help it to self-destruct with a process that is called programmed cell death. This is compared to the maintenance department of a business. The maintenance department is called in when there is old worn out machinery that needs replaced and discarded. The Mitochondria of the cell is in charge of producing the energy through cellular respiration. This is compared to the power plant or the generator of the business to help the production of energy. There are a few extra parts of the cell that could not be put on the chart above. The Plasma membrane of the cell is the semi permeable that controls cellular transport. This is compared to the Logistics department of the business. This department is in control of what is shipped in and out of the business. The last one is the Ribosomes of the cell. This Ribosomes are like the protein builders or the protein synthesizers of the cell. This is compared to the factory workers of the business. The works build the products for the company.

charge on the ion?
1+
2+
3+
3-

Answers

The basis to this Qs. is that electrons are negatively charged, and protons are positively charged. Essentially, the reason for an atom’s neutrality is a balance between the proton(s)/ positive charge(s) and the electron(s)/negative charge(s). So when 3 electrons are lost, we have an extra 3 protons left. As the charge of the proton is positive, your answer is “3+”.

Answers

The most important thing to do is that kindly evacuate all the living forms living in the area where there is an excessive amount of algal bloom.

What do you mean by Algal Bloom?

Algal bloom may be defined as the dense layer of tiny green plants that occurs on the surface of lakes and other water bodies when there is an overabundance of nutrients on which the species of algae depends.

Algal bloom grows as a result of Eutrophication. These growing algal species consume all major nutrients like phosphorus and nitrogen and expand their numbers. As a result of this, other organisms of that area feel the scarcity of minerals and nutrients, due to this a large mass of death has occurred. Algal bloom makes the surrounding water oxygen defiecient. So, to prevent these types of activities, it is better to evacuate all living forms and provide them with the other environment.

Therefore, The most important thing to do is that kindly evacuate all the living forms living in the area where there is an excessive amount of algal bloom.
