3. The allele for round seeds is represented by R.

Biology
1 answer:
lutik1710 [3]2 years ago
5 0

Answer:

rr

Explanation:

Alleles that are recessive will be lower case. Alleles that are dominant are upper case. Since we have two recessive alleles represented by 'R', the alleles would be written as 'rr'.

Word Roots and Origins The word transcription is
Sophie [7]

Answer:

Transcription is the second step in central dogma of molecular biology. First step is replication, second is transcription, and third is translation.

In the transcription phase, DNA, which is already replicated, is transcribed to mRNA which is required to make proteins in the translation phase. The root words say it is a combination of "across" and "write". This means that DNA is going to be written in a new language "mRNA". So, this term has been used in biological process because it is the re-writing across the whole DNA to make a completely new strand of mRNA.

Hope it helps.

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

Which of the following statements is true?
pshichka [43]

Answer:

Option C. A hypothesis is considered false until proven true, is the correct answer.

Explanation:

Hypothesis is a statement that may be true or false. In hypothesis, a scientist make a statement which can be both true or false. For example, when a scientist analyze malaria disease, he make a hypothesis that malaria disease is caused due to bad air but when he perform an experiment, he concluded that the malaria is caused due to mosquitoes.

Baldness (B) is inherited as X-linked dominant disease. An affected male marries a homozygous recessive female. What is the prob
torisob [31]
This can be solved with Punnett squares. The affected male has the X^{B} y genotype, and the female is homozygous recessive. This means that she does not carry this, and therefore, will have the genotype XᵇXᵇ

While doing this Punnett Square, keep in mind that in order to have the male offspring affected, their genotype has to be X^{B} y

Since there are no X^{B} y, the probability of their male offspring inheriting this disease is 0%
