Identify the mixture of powdered chalk and

Biology
2 answers:
love history [14]3 years ago

Answer:

The correct answer is option 1.

Explanation:

The powdered chalk and the table salt both can make a homogeneous mixture in a water solution that can be separated with the help of two processes; filtration followed by the distillation.

The chalk powder dissolved in a solution of the salt and water can be separated with the help of the filter paper by the process of filtration.

The salt can be separated by the process of the distillation from the water or liquid and it remains as an extract.  

Thus, the correct answer is option 1.

The mixture would be :
1. Homogeneous; dissolving followed by filtration and distillation
salt dissolve in water and will be the filtrate and chalk will be the residue in the filter paper

hope this helps

Is the movement of water along the concentration gradient
Nuetrik [128]

Answer:

<em>- Is the movement of water along the concentration gradient: </em><em>Osmosis</em><em>. </em>

<em>- Is the use of energy to move the particles against the concentration gradient: </em><em>Active transport</em><em>. </em>

<em>- Is the movement of particles by diffusion without energy: </em><em>Simple diffusion</em><em>. </em>

<em>- Is the movement of particles along the concentration gradient: </em><em>Passive transport</em><em>.</em>

Explanation:

The mechanisms of cellular transport involve all the processes that the cell carries out to incorporate substances into its interior or send them to the extracellular space, through its semipermeable cell membrane.

<h3>- Osmosis</h3>

Is a type of transport that consists of the passage of water from a space with a lower concentration of solutes to one with a higher concentration, in order to reach equilibrium, following a concentration gradient.

The concentration gradient is given by the difference in concentration between two substances, which indicates the direction in which molecules, such as water, should move from one place to another.

<h3>- Active transport</h3>

Unlike passive transport mechanisms, which depend on a concentration gradient that determines the movement of particles, in active transport there are two characteristics that define it:

The passage of substances into the cell against a concentration gradient.

The use of energy to carry out this process.

In this case, the passage of substances through the cell membrane will be according to the requirements of the cell, or when they cannot pass through the membrane.

<h3>- Simple diffusion</h3>

According to the characteristics of the cell membrane, some substances can pass freely through it while others require special mechanisms. When a molecule is able to pass through the membrane without the use of special mechanisms or energy we speak of simple diffusion.

In a cell membrane, whose composition is by hydrophobic or non-polar lipid molecules, simple diffusion allows the passage of non-polar molecules, gases and alcohol.

<h3>- Passive transport</h3>

Refers to the mechanism of entry and exit of substances from the cell that does not require the use of energy.

The mechanisms involved in the passive transport of the cell are simple diffusion, osmosis, facilitated diffusion - which requires special conveyors or channels - and ultrafiltration, which depends on hydrostatic pressure. Examples of substances using this mechanism are lipid molecules, water and electrolytes.

What happens when a atom loses an electron
Alex Ar [27]

It has a charge shift, which basically means, since there are 2 charges, that it'll filp it's charge:

- If the atom had a positive charge, it'll become negative

- If the atom had a negative charge, it'll become positive



Hope it helped,

In cells where telomerase is normally inactive, it can become active by accident and often, cancer will develop as a result. Can
vesna_86 [32]

Answer:

Cancer cells achieve proliferative immortality by activating or upregulating the normally silent human TERT gene (hTERT) that encodes telomerase, a protein with reverse transcriptase activity that complexes with other proteins and a functional RNA (encoded by hTR, also called hTERC) to make a ribonucleoprotein enzyme.

Explanation:

A rare cell that escapes crisis almost universally does so by reactivating telomerase and this cell can now become a cancer cell with limitless potential to divide. Almost all cancer cells have short telomeres and thus inhibitors of telomerase should drive such cancer cells into apoptotic cell death. Yet, each time a cell divides, the telomeres get shorter. When they get too short, the cell no longer can divide and becomes inactive or "senescent" or dies. This process is associated with aging, cancer, and a higher risk of death.

On Florida's beaches, what plant plays a vital role in the development of sand dunes? sea grapes beach sunflower sea oats saw pa
andrew11 [14]
Answer - sea oats

Sea oats play a vital role in the development of sand dunes. The structure of their leaves and roots help in the trapping of the wind blown sand, promoting the growth of sand dunes and their stabilization. Sea oat plantation is encouraged in coastal areas to protect damage from heavy winds and high tide.
