7 0

Answer:

Provide a closed environment.

Clean the hatch chamber with chemical.

Explanation:

Biosecurity  is a measure which is taken in order to protect or prevent the population of existing species from infestation of harmful organisms and chemical substances. The hatchery should provide a closed environment in order to prevent the entry of harmful organism. Cleaning of the chamber where eggs were hatched with chemicals in order reduce the infestation of microorganism.

How do the unsaturated fatty acids in phospholipids affect the structure of cell membranes?
ludmilkaskok [199]

Unsaturated fatty acids are a component of the phospholipids in cell membranes and help maintain membrane fluidity. The Phospholipids contain a variety of unsaturated fatty acids, when compressed, the “kinks” in their tails push adjacent phospholipid molecules away, that helps in maintain fluidity in the membrane. Unsaturated fatty acids have at least one double bond, creating a "kink" in the chain, the absence of double bonds decreases fluidity, making the membrane very strong and stacked tightly.

The ratio of saturated and unsaturated fatty acids determines the fluidity in the membrane at a temperature, at appropriate temperatures the phospholipids have enough kinetic energy to overcome the intermolecular forces holding the membrane together, which increases membrane fluidity.

20 points & Brainliest answer quickly plsssss
torisob [31]

Answer:

Answer: D; Irregular shape

Explanation: I'm not entirely positive but I do believe that the factor they're wanting you to notice in this question is the shape, as it states "deposition of the jagged particle". The shape affects the rate, as in the notes directly from the video it states "round particles settle more quickly".

The inhabitants of the planet Mendel have three alleles for hair color: red (R), white (W) and blue (b). The R and W alleles exh
Alex_Xolod [135]

Answer:

4 RW pink hair color

Explanation:

Let the allele for red hair color = R

Let the allele for white hair color = W

Let the allele for blue hair color = b

Since R and W exhibit co dominance it means none of both traits have the tendency or capability to masked the other .

As such individual with RW genotype = PInk hair color

Allele b is recessive and only individuals with the genotype bb exhibit the blue allele  

Now; if a cross occurs between a red-haired Mendelian and a white-haired Mendelian

i.e

RR   × WW

we have

           R           R

W         RW       RW

W        RW         RW

So we have the following offspring :

4 RW = 4 pink

So theoretically , the possible phenotypes results to 4 RW pink hair color

pshichka [43]

to determine whether traits can be inherited independently

Explanation:

the use of dihybrid crosses allowed him to discover the law of independent assortment / discovering that each locus had 2 alleles which segregate during the creation of gametes.
