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:

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:

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.

Explanation:

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:

B. Basic

Explanation:

Hydroxide (OH) is an anion with the chemical formula OH-. As the formula implies, it consists of an oxygen atom and a hydrogen atom. The more electronegative oxygen atom shares electrons with the less electronegative hydrogen atom via covalent bonding.

Hydroxide ion dissolves in water to form a very strong base, hence, an aqueous solution that contains lots of hydroxides will be BASIC or ALKALINE. A solution with lots of hydroxide ions is a STRONG BASE.

Answer:

The water needed for photosynthesis is absorbed through the roots and transported through tubes to the leaf. The roots have a type of cell called a root hair cell. These project out from the root into the soil, and have a big surface area and thin walls. This lets water pass into them easily.

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.

Answer:

Explanation:

nucleus

The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA.

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.

Explanation:

The climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.

Cryosphere is defined as solid precipitation, snow,  sea ice, lake and river ice, icebergs, glaciers and ice caps, ice sheets, ice shelves, , and seasonally frozen ground are all components of the Earth's climatic system.

It can also be defined as the area of the earth's surface marked by the presence of water.

Hydrosphere is defined as the total mass of water on, beneath, and above the surface of a planet, minor planet, or natural satellite.

It can also be defined as the component of the Earth made up of all liquid water.

There are basically three types of hydrosphere.

Climate change is defined as the long-term temperature and weather pattern shifts These changes could be natural, such as oscillations in the solar cycle.

Thus, the climate change increases the overall temperature of the earth, glaciers can melt into the ocean. The spheres involved cryosphere and hydrosphere. Thus option A is correct.

Nitrogen compounds in the soil ---> Plants

Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)

Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

Explanation:

This model in the image section is portraying the nitrogen cycle, which involves the transfer of nitrogen within biosphere, atmosphere, and lithosphere etc. The abiotic components of this model are the non-living parts while the biotic components are the living parts.

In this model, the movement of nitrogen from abiotic or non-living component of an ecosystem to the biotic or living component is as follows:

Nitrogen compounds in the soil ---> Plants

Nitrogen compounds in the soil ---> Denitrification bacteria (convert nitrogen compounds to N2)

Nitrogen in the atmosphere ---> Nitrogen fixing bacteria (convert N2 to nitrogen compounds)

Answer:

So in the case of a plant, a higher light intensity means more packets of light called “photons” are hitting the leaves. As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis.

Explanation:

If you continue to increase the intensity of light that a plant receives, what happens? The rate of photosynthesis increases with light intensity. The rate of photosynthesis decreases with light intensity. The rate of photosynthesis increases and then levels off.As light intensity increases (distance between lamp and plant decreases) the volume of oxygen (or the rate of bubble production) increases. This indicates that the rate of photosynthesis increases with light intensity.
