Answer:

Liquid, if you are meaning in terms of mass

Explanation:

Explanation:

On the other hand, lipids with unsaturated fatty acids (unsaturated fat) tend to be liquid at room temperature and thus they are called 'oils '. Lipids are present in all living organisms including Archaebacteria. ... Fats of animal origin are called as 'animal fat ' and those of plants are called 'plant fats'.

Answer:

Yes.

Explanation:

Yes, Schwann and Schleiden are responsible for the cell theory, both the scientists presented the cell theory in 1839. I agree with the argument of my classmate because the person who first presented cell theory was both Schwann and Schleiden. Schwann works on plant cell whereas Schleiden works on animal cell and formulate cell theory. So my classmate's argument is right about cell theory.

Schwan and Schleiden proposed the first cell theory, suggesting spontaneous generation. Virchow changed it proposing cell division. After many years and the contribution of many researchers, the modern cell theory emerged.

---------------------------------------------------

Schwann studied animal tissues. Through careful observation, he concluded that all animal tissues were made of cells.

Simultaneously, Schleiden arrives at the same conclusion when studying vegetable tissues.

Around 1830, they met and together proposed the first cell theory. The theory stated that:

1. Every living being is made of cells.

2. Cell is the basic unit of life.

3. Cells are originated from spontaneous generation.

Virchow, who studied human tissues, sow the cell in its dividing process.

He proposed that cells were not originated from spontaneous generation, as Schwann and Schleiden had stated.

Instead, he said that cells were the product of other pre-existing cells and were originated by cellular division.

Virchow rejected the third state of Schwann and Schleiden’s ideas.

According to these sequence of events, the original cell theory changed to

1. Every living being is made of cells.

2. Cell is the basic unit of life.

3. Cells are originated by cellular division.

After many years of continuous studies about cells and their functions, the modern cell theory emerged.

In general terms, the modern theory can be resumed as,

1. Every living being -unicellular or multicellular- is made of cells, which are the most basic units of life.

2. Cell control the vital functions of organisms.

3. Cells proceed from preexistant prokaryotic cells, and are originated by cellular division.

Explanation:

Answer:

The correct model is D.

Note: The first attachment below shows the different models. The second attachment shows the correct structural model of the water molecule.

Explanation:

A water molecule is composed of one atom of oxygen and two atoms of hydrogen.

A water molecule is polar, i.e. it contains positively and negatively opposite ends. The polar nature of the water molecule is due to strong electronegativity of oxygen which results in an uneven sharing of the bonding electrons between oxygen and hydrogen. The oxygen atom attracts the shared electrons more to itself, thereby, it acquires a partial negative charge, while the hydrogen atoms acquire a partial positive charge.

The bond angle between the oxygen and hydrogen atoms is approximately 105°. Therefore, from the first attachment below, the correct model for the water molecule is D.

Answer:

A - Fertilizer runoff can cause micro-organisms such algae to bloom out of control. B - Algae blooms suffocate the ecosystem if there is too much.

Explanation:

A - Not all fertilizer nutrients is used in agricultural production and so some of it makes its way into the excess water and therefore runs into creeks and rivers. It is also toxic to many animals in high concentrations as well as more sensitive native plants.

B - Algae blooms take a lot of oxygen out of the water, therefore suffocating natural wildlife. The decay that results from such large blooms is also problematic and takes away oxygen. Many algae likes slow moving water with little flow and in these optimal conditions with excess nutrients (Nitrogen, Phosphorus, and Potassium, NPK are the main ones) cause it to become out of control

B (graph 2)

Explanation:

I got it right on Edge ;)

Diffusion is not active and instead a form of passive transport. So the correct option is option C.

Because diffusion is a non-electrical process, small particles move faster than larger ones. For example, molecules such as oxygen, CO2, and glucose move through cells.

Active transport involves moving molecules from a low-concentration region to a high-concentration region. In contrast to diffusion, active transport involves moving molecules against a concentration gradient.

The term “active” refers to the fact that transport is energy-dependent. Active transport is energy-intensive, whereas diffusion is energy-free.

C the lipids makes your energy from running out soo soon

Carbohydrates and lipids are essential biomolecules for living. They both helps to store energy. Hence, option C is correct.

Carbohydrates are macromolecules formed from the monomeric units sugars such as glucose, fructose, galactose etc. These monomer molecules polymerise to form carbohydrates such as starch, cellulose, glycogen etc.

Lipids are formed by fat and triglycerols and they they store energy in skin cells. Lipids are important biomolecules because they have significant role in the cell wall formation in plants and cell membrane formation in animals as well as aids for the transport of ions through cells.

Carbohydrates are the main source of energy in animals and plants. It is stored in the form of ATP formed by glycolysis. Hence, both lipids and carbohydrates stores energy.

if it does not function properly it causes diabetes (sugar)

(ii)pituitary- it secrets growth hormone

it's function is to regulate the growth in human body

if it produces lots of hormone then the body will increase a lot in size known as gigantism

if it produces very less hormone then the body will not increase in size and will be very short known as dwarfism

(III)thyroid gland-it secretes thyroxin

its function is to maintain metabolism growth

lack of iodine makes this gland swell up known as goitre.

(iv)Adrenal gland - it secrets adrenaline
