7 0

Good Morning! The main function of the pulmonary alveoli is to perform the transfer and exchange of gases. In this case, the following gases are included: a) oxygen, c) carbon dioxide and d) gases. Of the elements listed, the only one that is not transferred by the alveoli is the blood, which corresponds to letter b). Hugs!Hope this helps. Let me know if you need additional help!

Its just what their diet is made of, meat, mainly other fish. So if there is blood around, there is probably food around.

Which of the following best describes Samuel Gompers?

xxTIMURxx [149]

Answer:

Option D

Explanation:

Samuel Gompers was the head of the largest labor federation of America known as American Federation of Labor. This organization comprised of workers that were skilled artisans, weavers, carpenters etc. He also headed the labor movement after actively forming a union of workers in the cigar industry. He himself was a cigar worker and thus could relate to the plight of the people working there. Young aged children were employed in cigar factories and the wage and benefits were not even enough to support survival of one.

Thus, Samuel arouses his voice to stand against the injustices done to the workers in cigar factory which later turned out to be mass movement.

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

3/4 long stem, 1/4 short stem

Flower color

Parental) Pp x Pp

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

3/4 purple flowers, 1/4 white flowers

Peas

Parental) Rr x Rr

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

3/4 round peas, 1/4 wrinkled peas

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

Note: The symbol - is representing either a dominant or a recessive allele.

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 = 9/64 L-P-rr

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.

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

A mixture of mineral grains and rock fragments organic material water and gas that can support plant growth is called

Nataly_w [17]

Soil

Soil is the upper layer of the ground comprising of a mixture of sand, silt, clay, loose rock fragments, and organic matter that can support the growth of rooted plants. The relative proportions of sand, silt and clay determine the texture and size of the pores of the soil, which affects its ability to allow air and water to penetrate/infiltrate.
