Answer:

There is no short answer.

Explanation:

The total energy that the flowers contain is 100.000 units and this gets transferred to the butterflies once they eat the flowers. The butterflies are then eaten by the birds who take on the remaining amount of energy.

The amount of energy that is transferred to the birds should be 100.000 units minus the total energy that was spent by the flowers and butterflies during the time until they were consumed by the next link in the chain.

I hope this answer helps.

(b) No. HIV can only be caught by another person of they come in contact with your blood or through sexual intercourse. So it is not possible for others to become infected if they didn't come in contact with the person's blood or have unprotected intercourse. There is no reason for a HIV+ve person to isolate themself from the outside world. They are people just as we are but they only have something that can cause them to be really sick.

<span>John could make some simple changes to his breakfast to increase his fiber intake. Instead of orange juice, he could drink juice with added fiber such as V8 juice or fiber added grape juice. Instead of corn flakes, he could eat a high fiber cereal such as Grape Nuts. Instead of white toast, he could eat a slice of high fiber whole wheat bread. He can make some simple substitutions that will really impact his diet and his health.</span>

In fruit flies, straight wings are dominant and curly wings are recessive. What will the generations look like? Assume that Mend
anzhelika [568]

Answer:

The P generation has straight wings and curly wings.

The F1 generation has all straight wings.

The F2 generation has straight wings and curly wings.

Explanation:

This question involves a single gene coding for wing shape in fruit flies. The allele for straight wings (S) is dominant over the allele for curly wings (s). This means that allele "S" will mask the phenotypic expression of allele "s" in a heterozygous state.

According to the question, the cross follows all Mendel's method of crossing two true breeding parents with opposite traits. Hence, the parent generation (P generation) will be between a truebreeding straight wings parent (SS) and a truebreeding curly wings parent (ss). (See attached image for full cross).

Since the straight wing allele (S) is dominant, all the F1 offsprings  will possess straight wings with the genotype: Ss, which is heterozygous.

If this F1 offsprings are self-crossed i.e. Ss × Ss, four possible offsprings in the phenotypic ratio 3 straight wings : 1 curly wing will be produced in the F2 generation. The offsprings will possess the following genotypes: SS, Ss, Ss, and ss.

Offsprings SS, Ss, and Ss will all be phenotypically straight-winged

Offsprings ss will be phenotypically curly-winged.

In overall, this means that P generation has both straight and curly wings (SS and ss), F1 generation has only straight wings (Ss), F2 generation has both straight and curly wings (SS, Ss and ss).

Why is milk used as a first-aid remedy for someone who has swallowed a heavy-metal poison?
klio [65]
Human trials have indicated an inverse relationship between blood lead level and calcium intake. While milk isn’t an antidote to let’s say, lead poisoning, the dietary calcium inhibits the lead absorption. This sort of poisoning is incredibly dangerous to the systems of the human body, and the ingredients within the milk help to defend against it. The purpose of the milk is to dilute the ingested poison.

What distinguishes archaea from animal cells? View Available Hint(s) What distinguishes archaea from animal cells? Archaea's RNA
lapo4ka [179]

Answer & Explanation:

All archeas are single-celled organisms, and despite having prokaryotic cells, there are both similarities and differences between archaea and bacterial cells and also with eukaryotes.

Archaea have only one cell that has no nucleus or real organelles, and its cells have membranes composed of branched lipids, which greatly alter the structure of the archaeal cell membranes. In addition, the archaea have only one DNA strand (uniqueness).

Animal cells differ from archeas because they are multicellular (organisms with several cells), each one having a nucleus, and they also have specialized organelles.

In addition, animal cells have compounds called phospholipids in their membranes, which are unbranched lipids, and therefore do not cause major changes in the structures of their cells. Finally, animal cells have double-stranded DNA (complementary duplication).
