lukranit [14]
As electrons move along the chain, hydrogen ion are pumped from the stroma of the chloroplast into thylakoid lumen. these leads to creation of proton gradient in thylakoid lumen with the potential energy that will be used to synthesize ATP by enzyme ATPase in the process referred to as rotational catalysis. both chloroplast and mitochondria use electron transport chain to pump protons across the membrane and both enzyme ATPase to produce ATP using proton gradient created in the process of transport of hydrogen ions. the main existing between the electron transport chains of chloroplast and mitochondria is the initial source of energy. chloroplasts obtain their energy from sunlight whereas mitochondria obtain theirs from organic molecules.

ololo11 [35]

Answer:

The statement “force equals mass times acceleration” is Newton's second law of motion. It is a law rather than a theory because it states, rather than explains, the relationship between the variables.

Dmitry [639]

Answer:

Explanation:

Cerebral Palsy is a brain injury it occurs while the brain is developing this could be before, during, or after birth. Mutation which is a sudden heritable change in the genome of an individual can result into cerebral palsy when the child is still developing. Mutation affects the gene changing it from it normal state to an abnormal one some mutation can be beneficial but for palsy it is detrimental one affecting the growth and development of the child.

severe jaundice in the infant could also lead to cerebral palsy in an infant child

This damage affects child’s muscle control, muscle coordination, muscle tone, reflex, posture and balance.

It can also impact a child’s fine motor skills, gross motor skills, and oral motor functioning

<span>11.2 Florida voters. Florida played a key role in the 2000 and 2004 presidential elections. Voter registration records in August 2010 show that 41% of Florida voters are registered as Democrats and 36% as Republicans. (Most of the others did not choose a party.) To test a random digit dialing device that you plan to use to poll voters for the 2010 Senate elections, you use it to call 250 randomly chosen residential telephones in Florida. Of the registered voters contacted, 34% are registered Democrats. Is each of the boldface numbers a parameter or a statistic? Answer 41 % of registered voters are Democrats: parameter 36% of registered voters are Republicans: parameter 34% of voters contacted are Democrats: statistic 11.7 Generating a sampling distribution. Let’s illustrate the idea of a sampling distribution in the case of a very small sample from a very small population. The population is the scores of 10 students on an exam: The parameter of interest is the mean score μ in this population. The sample is an SRS of size n = 4 drawn from the population. Because the students are labeled 0 to 9, a single random digit from Table B chooses one student for the sample. (a) Find the mean of the 10 scores in the population. This is the population mean μ. (b) Use the first digits in row 116 of Table B to draw an SRS of size 4 from this population. What are the four scores in your sample? What is their mean ? This statistic is an estimate of μ. (c) Repeat this process 9 more times, using the first digits in rows 117 to 125 of Table B. Make a histogram of the 10 values of . You are constructing the sampling distribution of . Is the center of your histogram close to μ? Answer (a) μ = 694/10 = 69.4. (b) The table below shows the results for line 116. Note that we need to choose 5 digits because the digit 4 appears twice. (c) The results for the other lines are in the table; the histogram is shown after the table.</span>
