Answer:

I agree with Joelle.

Explanation:

Just out of common sense, not all cells are the same.

  • The Facts:

-Sienctists have studied and evaluated that cells in different matter have different make-ups. For instance, plant have cell walls and a cell membrane while animals (incluing humans) only have a cell membrane. Plants have a chloroplast, used to make their own food using the process photosythesis, While animals don't, an consume other living things.

  • Using the Table:

-I don't know if you have to fill it out or anything, but if you were to fill it out, You'd put a check under each cell part for each thing.

(Not sure about the frog blood)

8-4 Discounting the Transverse Carrier Model. At one time, membrane biologists thought that transport proteins might act by bind
Natasha_Volkova [10]

Answer:

The two main reasons are nonpolar core of the bilayer and the active transport.

Explanation:

The membrane is structured to have two outer layers that are polar and an inner layer that is nonpolar.

If a membrane protein is exposed to the solvent, i<em>t will also have a polar side. It would be very difficult for the polar face of the membrane to move through the nonpolar core of the bilayer.</em> Therefore, this model is not feasible.

One major form of transport, active transport, moves solutes up the concentration gradient. <em>The binding of a solute and then release on another side of the membrane would only work for facilitated diffusion because it would cause a net movement of solutes down the concentration gradient.</em> It is unclear how energy could be expended to drive this process in the transverse carrier model.<em> Therefore, the transverse carrier model does not explain active transport.</em>

Answer:

Organism with AABBCCDD genotype will produce only one type of gamete, ABCD and the organism having the genotype AaBbCcDd will produce 16 types of gametes.

This is a percentage of 3.1%

In pea plants, long stems are dominant to short stems, purple flowers are dominant to white, and round peas are dominant to wrin
meriva

Assuming the genes are not linked nor interacting with each other, the expected number of long stemmed plants with purple flowers, producing wrinkled peas, L-P-rr, is 288.

<h3>Available data</h3>

  • long stems are dominant to short stems
  • purple flowers are dominant to white,
  • round peas are dominant to wrinkled

  • Each trait is determined by a single, different gene.

  • A heter0zyg0us plant is self-crossed
  • F1) 2,048 descendants

Let us name te alleles as follows

  • L ⇒ Long stem
  • l ⇒ Short stem
  • P ⇒ Purple flowers
  • p ⇒ white flowers
  • R ⇒ Round peas
  • r ⇒ wrinkled peas

Cross) heter0zyg0us plant is self-crossed

Parental) LlPpRr

Gametes) LPR, LPr, LpR, Lpr, lPR, lPr, lpR, lpr

Assuming that these genes are not linked nor interacting with each other, to make the calcs easier we will make crosses considering each gene separately.

  • Stems

Parental) Ll  x  Ll

F1) 1/4 LL, 2/4 Ll, 1/4 ll

     <u>3/4 long stem,</u> 1/4 short stem

  • Flower color

Parental) Pp  x  Pp

F1) 1/4 PP, 2/4 Pp, 1/4 pp

     <u>3/4 purple flowers</u>, 1/4 white flowers

  • Peas

Parental) Rr  x  Rr

F1) 1/4 RR, 2/4 Rr, 1/4 rr

     3/4 round peas, <u>1/4 wrinkled peas</u>

Now, we will get the proportion of individuals with long stems, purple flowers, producing wrinkled peas, L-P-rr

<u><em>Note</em></u><em>: The symbol - is representing either a dominant or a recessive allele.</em>

From the crosses, we know that

  • 3/4 are long stemmed,
  • 3/4 have purple flowers, and
  • 1/4 have wrinkled peas.

To get the proportion of individuals expressing all these traits together, we just need to multiply these values.

3/4 L- x 3/4 P- x 1/4 rr =<u> 9/64 L-P-rr</u>

Knowing that  the total number of plants is 2,048 and that there are 64 possible gametes combinations from this cross, we will use the proportion 9/64 to get the number of plants with these traits.

64 ------------- 2,048 plants

9 -------------- X = (9 x 2048) / 64 = 288 plants.

<em>We expect to find 288 long stemmed plants with purple flowers, producing wrinkled peas.</em>

babunello [35]

Answer:

Straight line path.

Explanation:

Speed is the rate at which an object covers a particular distance. According to the question, the object was moving with constant speed, there is no change in the direction as well, This imply that the object is moving with constant velocity.  No external forces applied on the object. Therefore the object is moving on a straight line path.
