Answer:

that the salted water osmolarity was bellow 300mOsm/L.

Explanation:

A solution with osmolarity bellow 300mOsm/L is known as hypotonic and will cause a cell to swell and eventually burst if equilibrium is not reached

Paul [167]

Answer:

GL, Gl, gL, and gl

Explanation:

The mom is glossy long haired. Since glossy (G) is dominant over to dull (g) and long hair (L) is dominant to short hair (l), the possible genotypes of the mom would be:

GGLL, GgLL, GGLl, or GgLl

The dad is dull and short haired, the genotype would be ggll.

GGLL x ggll

Progeny = all GgLl (all glossy long haired)

GgLL x ggll

Progeny = 8 GgLl, 8 ggLi (glossy long haired and dull long haired)

GGLl x ggll

Progeny = 8 GgLl, 8 Ggll (glossy long haired and glossy short haired)

GgLl x ggll

Progeny = 4 GgLl, 4 Ggll, 4 ggLl, 4 ggll (glossy long, glossy short, dull long, and dull short)

<em>Only a cross of ggll with GgLl produced the offspring that cover the phenotypic range shown in the illustration. Hence, the genotype of the mom is GgLl.</em>

The parental gametes produced by the mom would be; GL, Gl, gL, and gl

While the introduction of the mutant synthetase gene restored some of the growth characteristics, this strain still does not gro

katen-ka-za [31]

Answer:

A and D

Explanation:

Transfer ribonucleic acid (tRNA) is a type of RNA that decodes mRNA (messenger RNA) into protein. This phenomenon is known as translation.

If the strain of mutant synthetase gene does not grow fast despite having growth characteristics, the following possibilities could happen:

Sometimes histidine tRNA sends asparagine instead of histidine to other proteins where histidine residue should have been present for growth.

The normal synthetase might be present but not in an adequate amount.

In a flowering plant, tall (T) is dominant to short (t), and blue flowers (B) is dominant to white flowers (b). A tall plant wit

Bumek [7]

<h3>Answer: </h3><h3 />

25%

<h3>Explanation:</h3>

Following a cross between <u>Ttbb</u> and <u>ttBb</u>, the resulting offspring would be:

TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb , TtbB , TtbB , Ttbb , Ttbb , ttbB , ttbB , ttbb , ttbb

To have a clearer idea, see the attached image.

Of the 16 possible combinations from this dihybrid cross, there will be:

4 tall plants with blue flowers

4 tall plants with white flowers

4 short plants with blue flowers

4 short plants with white flowers

There are 4 possible genotypic recombinations that would yield short plants with white flowers out of a possible 16, so the chance that the offspring will be short with white flowers would be 4/16 which is 1/4 or 25%

<h3>Hope this helps</h3>

Imagine you were going to build a “green” building. What features would it have? What would it look like? How would it harmonize

9966 [12]

Answer:

Green building is a modern concept in architecture by means of which it is aimed at construction developments that are not invasive with the environment, or that affect the ecosystem in which they are built as little as possible, with the aim of leaving future generations an intact environment worth living in.

Thus, for a construction to conform to this concept, it must follow the following parameters:

-The construction must adapt to the natural environment, and not this to the construction.

-It has to be resource-efficient. Furthermore, the materials used must not be exploited indiscriminately or causing damage to the environment.

-The external area of the building must respect the natural patterns of the area where it is built, favoring a harmonic view between the building and the surroundings.

-Use of clean and renewable energy to supply the building.
