PLS SOMEONE DRAW ME Punnett square FOR THIS ASAP,

Biology
1 answer:
allochka39001 [22]3 years ago
4 0

Answer:

Punnett square drawn below:

Explanation:

Sorry if it's messy. Since brown coat is dominant to black coat, that would mean that the genotype for brown is either Aa or AA. Since it says it's a pure breeding brown mouse and that all of the offspring are brown, that means that the genotype for the pure breeding brown mouse is AA. As for the black coated mouse, black is reccessive, meaning the genotype would be aa. So... AA x aa = 100% Aa

Most amines are ________, meaning they dissolve in water and therefore cannot cross the cell membrane. The ________ hormones are
Doss [256]

Answer: 1. Lipophobic

              2.Thyroid

              3.lipophilic

Explanation:

 Chemical messengers can be classified by their chemical characteristics including their solubility in water and their chemical structure.  

Depending on their solubility in water they can be classified in two groups:

  • Hydrophobic (lipophilic) - Molecules are lipid soluble and can easily cross the plasma membrane.

  • Hydrophilic (lipophobic) - Molecules that are water soluble and do not readily cross the plasma membrane.

Depending on the chemical structure  

Amino Acids are lipophobic.

Amines are derived from amino acids and contain an amine group (-NH2, known as the amino group). An important group of these are the catecholamines which contain a 6 carbon ring (catechol) and are derived from tyrosine. These include dopamine, norepinephrine and epinephrine. The thyroid hormone is derived from tyrosine.  All except thyroid hormones are hydrophilic. The thyroid hormone is lipophilic (hidrophobic)

What does the number of offspring tell us about the number of eggs fertilized?
kolezko [41]

The number of eggs fertilized in a perfect situation SHOULD be the number of offspring. However, outside factors can interfere with the birth of offspring. Typically the number of eggs fertilized SHOULD be identical to the number of offspring but is typically leas than the number of eggs fertilized.

What is the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells at night w
lions [1.4K]

Answer:

C. +23.1 kJ/mol

Explanation:

the formula to use to calculate the energy requirement in kJ/mol to transport a proton across the mitochondrial inner membrane in plant cells is:

ΔGt = RTIn  \frac{C_{2} }{C_1}   + ZFΔV

let's list the values of the data we are being given in the question to make it easier when solving it.

Z= 1

F= 96500C (faraday's constant)

ΔV= 160mV = 0.160V

R= 8.314( constant)

T= 15ºC ( converting our degree Celsius into kelvin, we will have 273.15k+ 15 = 288.15K)

∴ T= 288.15K

Putting it all together in the formula, we have:

ΔGt = 8.314 × 288.15 × 2.303 log \frac{C_{2} }{C_1}  + 1  × 96500 × 0.160

ΔGt = 5517.25   [ -(log(H^{+}_{out} ) + log(H^{+}_{in} )_{in}  +15440

ΔGt  = 5517.25 (pH_{out} - pH_{in}  +15440

Given that the pH  differential gradient  across the membrane is 1.4pH units. It implies that;

ΔGt  = 5517.25 × 1.4 + 15440

=  7724.15 +15440

= 23164.15 Joules/moles

= +23.1 KJ/mole
