The potassium ions are positively charged(cations) if the charge is -70mV the outflow of cations will cause a decrease in the potential. The potential will become lower than -70mV.

Which meal is high in fiber, low in saturated fats, and high in unsaturated fats? a) beef, potatoes, and carrots
inn [45]

a plate of scrambled eggs with a side of cottage cheese. Thus option D is correct.

<h3>what is the difference between saturated and unsaturated fats ?</h3>

Saturated fats are composed up of carbon, hydrogen, and oxygen molecules.

They have the greatest number of hydrogen atoms possible with no double bonds in their chemical structure, so that it become solid at room temperature.

Animal meat, plant oils, Dairy products like milk, Processed meats, Pre-packaged snacks including crackers, chips are saturated fat containing foods.

Unsaturated fats contains one or more double bonds and liquid at room temperature.

It can be up two types, such as Monounsaturated fats have only one double bond in its structure, example canola oil and olive oil.

Polyunsaturated fats have two or more double bonds  include  sunflower oil, and corn oil.

Thus option D is correct.

This zone has the greatest concentration of plankton in a freash water lake ecosystems
ZanzabumX [31]
 According to an article/websites, the link stated below, plankton dominates the "limnetic" zone of freshwater ecosystems, which make sense since this is the topmost layer. This is the zone that receives the most sunlight, thus the plants can photosynthesize better than those at the lower levels. Plankton will rarely be found in the lowest zone as there is little to no sunlight there. The lower in the lake/freshwater ecosystem you go, the less plankton you'll find because of their lack of ability to photosynthesize. You can refer to the website below and other books/websites like it for more in-depth information on plankton and their role in freshwater ecosystems. Hope this helps.

At the end of the term, the professor locks the students in the classroom with plenty of food and water and leaves them there fo
levacccp [35]

Answer:

a. 0.7

b. 0.3

c. Yes

d. 90

Explanation:

As the random mating population was escaped from external evolutionary forces such as mutation, natural selection, and migration, the gene frequency will not change over time. The population will be at Hardy-Weinberg equilibrium throughout the time.

<u>As the number of sleepyheads (recessive trait) was 90 out of class of 1000 students at the start of course.</u>

<u />

q²=0.09 ∵ fraction of sleepyheads = 90/1000 = 0.09 denoted by q²

q that is the recessive gene frequency will be equal to 0.3 (by taking square root of P²

Hence, <em>allele frequency of a allele is 0.3</em>

<em></em>

As, frequency of dominant allele A is denoted by letter p and p+q=1

∴ p=0.7 As p=1-0.3

Hence,<em> allele frequency of A allele is 0.7</em>

<em></em>

Counting the probability of aa alleles (sleepyheads);

As a= 0.3

∴ aa= 0.3×0.3 = 0.09 (In terms of percentage, it is 9%)

To 0.09×1000= 90 or 9% of 1000 = 90

Hence, 90 students should be sleepyheads.

In snakes, being rude ( R ) is dominant to being respectful (r), and being sneaky (S) is dominant to being sincere (s). A female
Mashutka [201]

Answer:

Zero (0).

Explanation:

As per the question, the male snake will have genotype RRSS while the female snake will have genotype rrss. The male snake will produce 4 identical gametes which will have "RS" genetic combination while female snake will produce 4 identical gametes with "rs" genetic combination.

The cross depicting the genotypes of their off-springs is attached.

It is clear from the "Punnett square diagram" that all their progeny will have "RrSs genotype" which simply means that all the progeny will be heterozygous dominant and therefore phenotypically they all will be rude and sneaky. It also implies that no progeny will have rrss genotype which could make it respectful and sincere so the probability is zero.
