A sodium-potassium pump within a cell membrane requires energy to move sodium and potassium. the movement of glucose does not re

quire energy. what is the movement of these materials
Biology

So sodium and potassium move by active transport using a pump

Glucose moves by a method of passive transport, facilitated diffusion. Ions moving with facilitated diffusion use channels, but a molecule like glucose would use a carrier protein.

In a certain plant, tall stems (t) are dominant to short stems (t). a farmer crosses a short-stemmed plant with a heterozygous l
melisa1 [442]

The answers would be:

Genotype                Phenotype

     Tt                      Tall stemmed

     tt                       Short stemmed

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2  or 1:1  

<u />

<u>You can read on to see how this was done:</u>

Tall stems (T) are dominant to short stems (t).

First figure out the genotypes of the parents. We have a short-stemmed plant and a heterozygous long-stemmed plant cross.

For short stem to occur, you need 2 pairs of short alleles. So the first parent would have a genotype of tt.

Heterozygous long-stemmed means that the parent has one of each allele. So the genotype of the second parent would be, Tt.

Now we can make our Punnett Square.

tt x Tt

<u>       t        t  </u>

<u>T |  Tt  |   Tt</u>

<u>t  |   tt  |   tt</u>

Let's list down the genotypes and phenotypic results.

Genotype        no.         Phenotype

     Tt                 2           Tall stemmed

     tt                  2           Short stemmed

So from that we can answer the other questions:

Genotypic ratio : 2:2 or 1:1

Phenotypic ratio: 2:2  or 1:1

which of the following is not an example of a trait a)eye color b)ear shape c) species d) body height​
Dmitry [639]
Eye color and ear shape are inherited.
Body height is mainly inherited/ influenced.
Species cannot be changed? So my guess is that C. Is the correct answer as it is not a inherited trait.
If that is wrong, then the answer is D. Because I would think body height is influenced by the two parents.

Birds, insects, and many reptiles excrete nitrogenous waste in the form of uric acid, which _____. is not very toxic compared to
attashe74 [19]
Reduces water loss compared to other nitrogenous wastes but requires more metabolic energy to produce

Mammals excretes urea as the primary nitrogenous waste product. On the other hand birds, and reptiles excretes uric acid as the primary nitrogenous product. They are called uricothelics because they can convert ammonia to uric acid. Uric acid is a compound similar to purines. This is produced through a complex metabolic pathway thay cost high energy. However it has advantages such as reducing water loss.
