Ferns often have small bumps called sori arranged in rows on their undersides. What are these structures?A) Spore capsules.
B) Seed capsules.C) Nodules containing symbiotic bacteria.D) Parasites.

Answers

Answer 1

Answer:

A) Spore capsules

Explanation:

Ferns produce spore capsules contained in the sporangium (plural: sporangia), a structure localized on the undersides of the leaves. Moreover, the sporangia are borne in clusters known as sori (singular sorus). The spores are single reproductive cells that, when mature, are released from the sporangium to germinate on soil and produce new ferns. In a fern sporangium, the maximum number of spores is 64, although this number depends on the species.

Why is phenylketonuria resulting from dihydropteridine reductase deficiency a more serious disorder than PKU resulting from phenylalanine hydroxylase deficiency?

Answers

Answer:

pteridine reductase deficiency alters all reactions known to be dependent on tetrahydrobiopterin (BH4)  

Explanation:

Hyperphenylalaninemia is a condition characterized by elevated concentrations of the amino acid phenylalanine in the blood. Dihydropteridine reductase deficiency (DHPR) is a severe type of hyperphenylalaninemia caused by the deficiency of tetrahydrobiopterin (BH4). BH4 helps to convert amino acids, including phenylalanine, to precursors of neurotransmitters. BH4 is an essential non-protein co-factor of enzymes associated with the biosynthesis of dopamine, serotonin, noradrenaline and adrenaline. DHPR is an inherited recessive disorder whose symptoms include mental deficiency, poor swallowing (dysphagia) and an abnormally small skull (microcephaly).

Answers

Answer:

C. Radial Symmetry

Explanation:

Diploblastic Animals are those animals whose blastula have basically two primary germ layers. These layers are called the endoderm and the ectoderm. On the contrary, most other animals have three layers found in them. The endoderm is an embryonic germ layer that gives rise to the gut. They also give rise to the tissues that form the internal organs. On the other hand, the ectoderm produces skin and nervous tissue and does cover the outside of the embryo. This type of body plan is particularly seen in cnidaria and ctenophora

An Earth scientist is testing how various soil mixtures affect plant growth. She begins with 10 soil types. For each mixture, she combines equal amounts of 2 soil types. How many soil mixtures must the scientist create in order to test all possible combinations of the 10 soil types?a. 20b. 45c. 55d. 90

Answers

Answer:

b

Explanation:

The correct answer would be 45.

Assuming that the 10 soils are each represented by A, B, C, D, E, F, G, H, I, J.

A can combine with 9 others as: AB AC AD AE A F AG AH AI AJ

B can combine as: BC BD BE BF BG BH BI BJ

C as: CD CE CF CG CH CI CJ

D as: DE DF DG DH DI DJ

E as: EF EG EH EI EJ

F as: FG FH FI FJ

G as: GH GI GJ

H as: HI HJ

I as: IJ

Adding all the combinations together = 45

In other words;

[tex]^{10}C_2[/tex] = [tex]\frac{10!}{(2!(10 - 2)!)}[/tex] = 45

The soil mixtures must the scientist create in order to test all possible combinations of the 10 soil types- b. 45.

Given

soil samples = 1, 2, 3, 4, 5, 6, 7, 8, 9, 10

each mixture must have two sample

SolutionWe have to mix 2 soils in equal amounts. Then, the total number of possible soil mixtures are:-1 and 2, 1 and 3, 1 and 4, 1 and 5, 1 and 6, 1 and 7, 1 and 8, 1 and 9, 1 and 10 = >92 and 3, 2 and 4, 2 and 5, 2 and 6, 2 and 7, 2 and 8, 2 and 9, 2 and 10 => 83 and 4, 3 and 5, 3 and 6, 3 and 7, 3 and 8, 3 and 9, 3 and 10 => 74 and 5, 4 and 6, 4 and 7, 4 and 8, 4 and 9, 4 and 10 => 65 and 6, 5 and 7, 5 and 8, 5 and 9, 5 and 10 => 56 and 7, 6 and 8, 6 and 9, 6 and 10 => 47 and 8, 7and 9, 7 and 10 => 38 and 9, 8 and 10 => 29 and 10 => 1

what is the type and morphology of Escherichia coli

Answers

Answer:

E. coli is a Gram-negative, facultative anaerobe (that makes ATP by aerobic respiration if oxygen is present, but is capable of switching to fermentation or anaerobic respiration if oxygen is absent) and nonsporulating bacterium. Cells are typically rod-shaped, and are about 2.0 μm long and 0.25–1.0 μm in diameter, with a cell volume of 0.6–0.7 μm3.

E.coli colonies on agar.

E. coli on sheep blood agar.

E. coli colonies

E. coli growing on basic cultivation media.

E. coli stains Gram-negative because its cell wall is composed of a thin peptidoglycan layer and an outer membrane. During the staining process, E. coli picks up the color of the counterstain safranin and stains pink. The outer membrane surrounding the cell wall provides a barrier to certain antibiotics such that E. coli is not damaged by penicillin.Strains that possess flagella are motile. The flagella have a peritrichous arrangement.It also attaches and effaces to the microvilli of the intestines via an adhesion molecule known as intimin.
