The answer you are looking for is D.

Explanation:

Lipids are molecules that contain hydrocarbons and make up the building blocks of the structure and function of living cells. (non- polar molecules)

Lipids are fat molecules and are hydrophobic (water repulsive) in nature. Thus, option D is correct.

Lipids are important biomolecules and are widely distributed in biological systems. Lipids are organic macromolecules.

Lipids are insoluble in water (polar) and require non-polar solvents mainly hydrocarbons for dissolution like petroleum, ether etc. Thus, non-polar in nature.

Lipids include array of molecules like fats, wax, steroids, vitamins (fat-soluble; A,D, E and K), hormones, oils etc and have diversified functions.

Lipids form an integral part of the cell membrane. It also surrounds membranous structures. It protects the cellular membranes by creating an insulating layer.

Lipids are essential for storing and conserving energy in mammalian body. It helps in metabolism of glucose by converting extra glucose to glycogen in adipose tissues.

Lipids also act as transport molecules in the body. Many lipids function as chemical messengers.

Therefore, Lipids play a pivotal role in living system.

Answer:

Density = 0.4g/cm³

Explanation:

Given

Mass = 12 g

Length = 3 cm

Required

Determine the density.

To calculate density, we need volume.

Volume of a cube is:

Volume = Length ³

Hence:

Volume = (3cm)³

Volume = 27cm³

Density = Mass/Volume

Density = 12/27

Density = 0.4g/cm³ --- Approximated

Answer:

Perspiration provides homeostasis to the internal condition of temperature balance.

Explanation:

Perspiration occurs as a consequence of the increase in environmental temperature, which at the same time produces an increase in body temperature.

The high body temperature produces a stimulus that reaches the thermoregulation center of the central nervous system, which produces a response transmitted through the sympathetic nervous system, causing the sweat glands to increase the production of sweat.

The sweat that covers the skin is capable of acting as a physical agent to lower the temperature, a mechanism of thermal regulation that contributes to temperature balance.

The other options are not correct because:

Answer:

All are methods to separate mixtures

Explanation:

A mixture consists of 2 or more substances that are mixed physically but not chemically. Hence, mixtures can be separated by any physical separation means which include but not limited to filtration, distillation, sieving, magnetization, and evaporation.

Filtration is usually used to separate suspended particles in a liquid using a membrane of a filter paper. Distillation is used to separate miscible liquids with varying boiling points by evaporating and condensing them back at their respective boiling points. Sieving is used to separate mixtures with varying particle sizes of individual components.

Magnetization is usually used to separate mixtures with, at least, one component with magnetic property. Evaporation is used to separate dissolved solids from liquids.

Hence, all the methods listed are used to separate mixtures.

Answer:

Gross primary production (GPP) is the total rate at which material is produced and net primary production (NPP) is the rate at which material is accumulated in excess of respiration. In other words, NPP is GPP minus respiration. ... Net primary production is directly related to ecosystem conditions.

Small population is the answer

Your welcome

According to the Charles darwin theory of natural selection, genetic diversity best allow a species to survive environmental changes.

Natural selection is the procedure via which populations of living organisms acclimate and modify.

Individuals in a population are naturally variable, indicating that they are all distinct in some manner. This divergence means that some individuals have characteristics better suited to the environment than others.

Natural selection leads to evolution.

Thus, genetic diversity best allow a species to survive environmental changes.

Answer:

Cell differentiation is how generic embryonic cells become specialized cells. This occurs through a process called gene expression. Gene expression is the specific combination of genes that are turned on or off (expressed or repressed), and this is what dictates how a cell functions.

Answer:

[tex]\boxed {\tt Golgi \ apparatus}[/tex]

Explanation:

After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.

In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.

So, the correct answer is Golgi apparatus.

Golgi apparatus

The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.

Answer:

Honey > Water > oil > air

Explanation:

Heavy density will sink and less heavy density will float

So,

Density of honey is highest so, honey will sink

than,

Density of water is higher so, vegetable oil will float

Density of oil is higher so, air will float

Honey > Water > oil > air

Answer:

Cool and dry

Explanation: Trees tend to be sensitive to climates, so when the conditions are good the trees grows faster which results in wider growth rings and in poor conditions the tree grows slower which results in it laying down less tissue and therefore a narrower ring size. Drought and a blizzard can also cause narrower ring too. Actually, a cool way to find out if the climate conditions were good is to measure the rings of a tree every month each year. If the rings were consistently the same then you know the climate stayed pretty much the same and etc.
