1. All of the following

To compost is to reduce your organic waste and turn that waste into fertilizer

2. Fertilizer

I'ts the main idea of composting.

3. Anaerobic bacteria

They live into dirt, that's why comspot start with a bin full of dirt.

4. Dairy products

This will rotten all your compost

5. Turn it

This way you incorpore air and kill bad bacteria

6. Fertilizer

It's a way to fertilize.

7. Processed foods

This food is full of chemicals and not good for your compost.

8. 20-30%

The idea is to reduce your daily waste.

9. Woodcuttings

Will take some months maybe, but eventualy will compost. Things like fruit peels will compost in some weeks.

10. Aerate

Like when cooking, you move, you aerate, you incorpore oxygen.

Which source of codis contains dna profiles from unsolved crime scene​ evidence?
user100 [1]

Answer;

-Forensic Index

Explanation;

-The Combined DNA Index System (CODIS) is an FBI-run database that blends forensic science and computer technology into a tool for solving violent crimes.

-CODIS enables Federal, State, and local crime labs to exchange and compare DNA profiles electronically, thereby linking crimes to each other and to convicted offenders.

-CODIS uses two indexes: the Convicted Offender Index, which contains profiles of convicted offenders, and the Forensic Index: which contains profiles from crime-scene evidence.

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.

To efficiently provide the ideal amount of nitrogen fertilizer, some farmers make use of a "chlorophyll meter" that measures the
NikAS [45]

Answer:

Chlorophyll is a green pigment found in chloroplast in plants. It absorbs sunlight during the process of photosynthesis. It is a chelate molecule. In a chelate molecule a central metal ion forms bonds with a large organic molecule made of carbon, hydrogen and other elements like nitrogen or oxygen.

In chlorophyll, magnesium is the central metal ion and it is bonded to a large organic molecule called as porphyrin. Porphyrin constitutes four nitrogen atoms to which the central magnesium is bonded in square planar arrangement. Since chlorophyll is responsible for the green color of the leaves, more the green color more the chlorophyll content and more is the nitrogen content. Hence, chlorophyll meter measures this green light and finds out if the plant needs more or less nitrogen.
