In what way does the interior surface of a cell membrane of a resting (nonconducting) neuron differ from the external environmen

katen-ka-za [31]

Answer: option C) negatively charged and contains less sodium

Explanation:

In the absence of any stimulus, a neuron is said to be resting. During this time, more positively charged potassium ions (K+) than sodium ions (Na+) occupy the interior of its cell membrane, whereas more sodium ions than potassium occupies the exterior - making the cell membrane to be electrically Polarized with net positive charge outside and a net negative charge inside the cell membrane.

Thus, the interior is negatively charged and contains less sodium ions

Water Cycle 1. How is water stored on Earth during the water cycle? 2. Water moves into the atmosphere through ____________ and

Naily [24]

Water Cycle:

1. It is stored in the ground.

2. Evaporation, transportation, precipitation

3. Runoff comes straight from precipitation. Infiltration is from the ground while run off never went in the ground.

4. It will usually end up in the same place, the ocean

5. Water levels rise, temperatures rise, CO2 in atmosphere increases

Carbon Cycle:

1. Carbon is important because it is one of the basic building blocks of life.

2. Trees, animals, grass, decomposition, combustion, fossil fuels

3. Carbon enters as photosynthesis.

4. Carbon enters water to the soil decomposition. Aquatic plants have plenty of water to work with, so their main challenge is getting enough sunlight and air.

6. By breathing in the oxygen from plants.

7. Two ways carbon return from animals into water is through cellular respiration and decomposition.

8. Combustion is when we dig up the fossil fuel and burn it, then what is left goes into the air starting the cycle again.

9. Deforestation reduces the capacity of forests to be carbon sinks.

Nitrogen Cycle:

1. Nitrogen is important because it helps us grow crops, and it produces grass for animal.

2. It comes from lightning and is named nitrogen fixation.

3. Ammonification and then transitions into nitrification and then to assimilation.

Phosphorus Cycle:

1. It forms part of life sustaining molecules like DNA and RNA.

2. Phosphorus is never found in the atmosphere.

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with allele

marshall27 [118]

Explanation:

A geneticist is mapping the chromosomes of the newly captured gremlin. Stripe is heterozygous for three linked genes with alleles Ee, Hh, and Bb, that determine if gremlins are evil (E), have hair (H), and biting teeth (B). In order to determine if the 3 genes were linked, a standard testcross was done, and the 1000 offspring ...

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has o

Anuta_ua [19.1K]

The question is incomplete. Here is the complete question.

In horses, the Overo gene, Ov, produces a white splotch pattern on the coat. The overo phenotype is seen only when a horse has one Ov copy, Ovov. Horses with two Ov copies, OvOv, die soon after birth are called white overo because they are completely white. Horses with no Ov copies are solid colored, ovov.

The Leopard complex gene, Lp, shows incomplete dominance and controls white spotting. One Lp allele, Lplp, produces the leopard phenotype, in which there are spots everywhere. Two Lp alleles, LpLp, produce the fewspot phenotype, in which the horse is mostly white with colored spots.

A horse that is both overo and leopard is called pintaloosa, and these horses are spotted with splotches. A horse that is overo and fewspot is considered fewspot because the white areas from Lp is indistinguishable from the white from Ov.

Suppose that 16 pairs of pintaloosa horses have one offpring per pair. How many each phenotype would be expected? Determine the number out of 16 expected for each phenotype. Only count phenotypes of offspring expected to live past one week of age.

overo:

white overo:

fewspot:

Answer: Overo: 2

White overo: 0

Fewspot: 3

Explanation: Pintaloosa is a "combination" of overo and leopard, so the pair's genotype is OvovLplp.

To cross a pair, use Punnet Square and to facilitate, use the square for each characteristics:

Punnett Square For overo and white overo:

Ov ov

Ov OvOv Ovov

ov Ovov ovov

Analysing this Punnett square, notice that there are 2 individuals who will carry the genotype for overo (Ovov) phenotype. So, 2 out of the 16 pair will have an overo phenotype.

Since white overo is recessive (ovov) and doesn't survive past birth, there will be zero horses with that phenotype.

Punnett Square For leopard and fewspot:

Lp lp

Lp LpLp Lplp

lp Lplp lplp

From this square, notice that there are 1 individual who is fewspot. However, a horse that is overo and fewspot is considered fewspot, so for the 16 pair, 3 out 16 will be fewspot.

Joan uses a model to show how wood burns at the level of atoms and molecules. Her model tracks 840 carbon atoms that make up a s

aksik [14]

Answer:

The correct option is A. Matter is conserved during the burning of wood

Explanation:

One of the major theories of matter states that the amount of mass at the start of a reaction is equal to the amount of the mass at the end of the reaction.

As in Joan's study, he shows that the amount of carbon atoms remain 840 during each of the combustion reactions. The number of carbon atoms in wood at the start of the reaction was equal to the number of carbon atoms in carbon dioxide at the end of the reaction. Hence, Joan's model supports the theory that matter is conserved during the burning of the wood.
