Answer

a balance and a graduated cylinder

Explanation

Density is mass per unit and it is property  characteristic of a substance. The arrangement of the mass of atoms and their size is what determines the the density of a substance.

For a student to measure the density of seawater  he/she is required to use a balance and a graduated cylinder where a balance will be used to measure the mass of the mineral sample  and then a graduated cylinder to determine the volume.

Lubov Fominskaja [6]

1st step: Transcription DNA is unraveled and used as a template to form complimentary mRNA mRNA then leaves nucleus in order to attach to ribosome and start 2nd step. 2nd step: Translation tRNA with aminoacids attached will try to join mRNA\ribosome complex if tRNA triple codon matches the mRNA code it will attach aminoacid to start forming protein. This process continues until mRNA reaches STOP code, resulting in a long chain of aminoacids. 3rd step: Protein folding and modification Usually performed by chaperonins and eventually golgi complex. Chaperonins assist in proper protein folding, while golgi apparatus performs final modifications.

Mekhanik [1.2K]

Answer:

b the turgor pressure will increase but the cell wall prevents the cell from exploding

Explanation:

The plant cells are exposed in a change of pressure liquid depending the quantity of solids that are inside and outside the cell. Like in this case, the hypotonic solution is the one that has less solids outside the cell, that is the reason why the water enters the cell to equilibrate the concentration of solids inside and outside the cell.

AVprozaik [17]

Answer:

In Labrador dogs, black coat is dominant to chocolate, normal vision is dominant to progressive retinal atrophy (PRA), and normal hip joint is dominant to hip dysplasia. All these genes assort independently. Two dogs that are heterozygous for alleles of all three genes are crossed. Using rules of probability (not a Punnett square), what is the chance that the first pup born to these dogs will be chocolate, have normal vision, and have normal hip joints?

BbVvHh x BbVvHh= BBVVHH, BbVvHh, BbVvHh, bbvvhh

Bb= black coat dominant

Vv= Normal vision dominant

Hh= Normal hip join dominant

probability of having a first born of these dogs will be chocolate, have normal vision and have normal hip joint is 0

Explanation:

As the punette square gives 3:1 phenotype having three black coat, normal vision and normal hip joint and one chocolate, progressive retina altropy and hip dysplasia

What is the difference between plankton, nekton and benthos?
Archy [21]
<span>The common difference between the three organisms is the area in which they specifically live or stay in the ocean. Planktons can’t be seen by the naked eye and they require microscopes to be detected. Planktons usually float in the water and they cannot move on their own that’s why they are dependent in the movement of the water.

Nektons are organisms that swim through the water and they live in different depths in the ocean ecosystem. Nektons are composed of fish and other mammals that propel themselves through the water.

Benthos are organisms that live in the ocean floor and many of these organisms stay in one place by attaching themselves to rocks. This adaptation protects them from crashing waves and drastic water movements. Other benthos are known to burrow in the ocean floor either for food or protection.</span>
