the mantle

Explanation:

2885 kilometers thick and is the middle layer of the Earth

the earth's mantle

the mantle is made up of several minerals such as iron, magnesium, silica and oxygen.

Answer: We are given:

Mass of solvent (water) = 100 grams

Mass of solute (NaCl) = 20 grams

Mass of the Solution:

Mass of Solution = Mass of Solute + mass of Solvent

100 + 20 = 120 grams

Mass Percent of NaCl:

We know that

mass percent of NaCl = (Mass of NaCl / Mass of Solution) * 100

replacing the variables

Mass% of NaCl = (20 / 120)*100

Mass% of NaCl = 100 / 6

Mass% of NaCl = 16.67%

Answer:

1) I identified the Golden-Brown Algae.

2)  It was very easy to find the category because of the solid color base and because it only had the daitoms. It did not have multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, brackish or salt water. They are found both in tropical lakes and seas, and in the alpine and polar snows. They are unicellular or multicellular protist plant organisms, whose cells do not form tissues and lack flowers. They are considered the first link in the food chain in the aquatic environment. They are found in fresh, brackish or salt water. They are primary producers in the food chain, capable of producing organic substances through photosynthesis, so they use sunlight. They are found in tropical lakes and seas up to the alpine and polar snows.

4) Producer Alga is A plant and produces food for other organisms.

5) Algae (Euglena) do photosynthesis as plants do. They also move around and eat, as do animals. But they are unicellular. In order to be classified as a plant or animal, an organism has to be multicellular, made of more than one cell. Since it is a unicellular organism with some plant and animal characteristics, it is called a protist. Plant cells have walls while algae does't have one, so it is a protozoan. Algae resemble the protozoa, so they are put into the Protist Kingdom.

Explanation:

I had the project.

Algae recreate a major part of the marine ecosystem because they exist as the decomposers current in the marine ecosystem; any harm to them could cause an inequality in the whole marine ecosystem.

1)The Chrysophyceae, usually named chrysophytes, cryptomonads, golden-brown algae or golden algae exist as an extensive set of algae, seen mainly in freshwater.

2) It stood very easy to see the class because of the solid color base and because it only contained the diatoms. It did not contain multiple like the Green Algae and the Blue-Green Algae.

3) In fresh, saline, or salt water. They exist seen both in tropical lakes and seas and in the alpine and polar snows. They exist as unicellular or multicellular protist plant organisms, whose cells do not constitute tissues and absent flowers. They exist thought the first link in the food chain in the aquatic environment. They exist seen in fresh, brackish, or salt water. They exist as primary producers in the food chain, qualified of producing organic substances through photosynthesis, so they utilize sunlight.

4) Producer Alga exists in a plant and makes food for different organisms.

5) Algae (Euglena) accomplish photosynthesis as plants do. They even move about and eat, as do animals. But they exist unicellular. To be categorized as a plant or animal, an organism contains to be multicellular, made of better than one cell. Since it stands as a unicellular organism with some plant and animal elements, it exists named a protist. Plant cells contain walls while algae don't contain one, so it exists as a protozoan. Algae reach the protozoa, so they stand to put into the Protist Kingdom.

Answer:

Check from the internet

Answer:

Object with 200kg

Explanation:

Newton's second law of motion depicts how the acceleration of an object depends on the force (F) and mass of the object (m). This law can be represented by the mathematical equation: F = ma

However, the acceleration of the object is inversely proportional to the mass i.e. a = F/m. This means that an increase in the mass of an object causes a decrease in acceleration of the object and vice versa.

According to this question, If the forces acting on two objects are the same, an object that is 200 kg will have a greater acceleration than an object that is 400 kg. Note: the higher mass the mass, the lower the acceleration and the lower the mass, the higher the acceleration.

Answer:

diffusion and osmosis

Explanation:

lipid_ soluble substance

through lipid baleyer

through protein channel

Transported proteins carry small substances like water, amino acids, and charged ions. One to fifteen angstroms is the range in molecule size that can pass through the membrane. The easier it is for a molecule to move across the cell membrane, the smaller it is.

All cells have a cell membrane, also known as a plasma membrane, which separates the interior of the cell from the external environment. A semipermeable lipid bilayer makes up the cell membrane. The movement of materials into and out of the cell is controlled by the cell membrane.

Small molecules or ions can traverse the cell membrane passively without the cell providing any energy. The three basic types of passive transport are osmosis, assisted diffusion, and diffusion.

Gases like oxygen and carbon dioxide, as well as small hydrophobic compounds, quickly traverse membranes. Water and ethanol are examples of small polar molecules that can move across membranes, though more slowly.

Thus, The easier it is for a molecule to move across the cell membrane, the smaller it is.

Answer:

The dominant (light green) parent was heterozygote for the trait

Explanation:

According to Gregor Mendel in his law of dominance, an allele is said to be DOMINANT if it masks the phenotypic expression of another allele in a gene. The allele being masked is called RECESSIVE allele. In this case of a frog whose allele for light green color is dominant over the allele for brown color, the light green color allele (G) is dominant while the brown color allele (g) is recessive.

However, in a cross between that have light green frog and a brown frog, a small brown frog is produced. This is possible despite the green color being dominant because the genotype of the light green dominant parent is HETEROZYGOUS i.e. it contains both light green (dominant) allele and brown (recessive) allele.

Hence, when a gamete with recessive allele (g) is produced by the heterozygous light green frog (Gg), it mates with a recessive allele from the brown frog (gg) to produce a brown offspring (gg).

Explanation:

Brainliest? plz

Electric fish is a part of the group of animals which are responsible for producing charge. These organisms pump positively charged sodium ions from inside themselves to the outside environment.

An electric fish is an fish that can generate electric fields and transfer current through themselves. Most of the electric fishes are electroreceptive, which means that these fishes can sense the electric fields present in the environment. The only exception here is the stargazer family which is not electroreceptive.

The examples of electric fish includes Electric eel, that belongs to the genus Electrophorus, South American knifefishes responsible for the production of powerful electric shocks to stun prey.

If the electric fishes are supplied with the negative charge always then they will pump positive charge to neutralize the effect of that charge.
