The largest amount of carbon dioxide is transported in the bloodstream in the form of carbonic anhydrase. True False
motikmotik

Answer: False, it is transported as bicarbonate

Explanation: Carbonic anhydrase is an enzyme belonging to the family of metalloenzymes that catalyzes the conversion of carbon dioxide and water to ions and carbonic acid. This enzyme is found in red blood cells where carbon dioxide enters by diffusion. Once it diffuses through it is then converted by carbonic anhydrase to bicarbonate and hydrogen ions.

That is how its transported in bloodstream, passes through the heart via the venous system, to the lungs. Therefore the answer is False.

A purebred tall pea plant is cross-pollinated with a tall, heterozygous pea plant. Use a Punnett square to determine the probabi
Ray Of Light [21]

Answer:

0%

Explanation:

This question involves a gene coding for height in pea plants. The allele for tallness (T) is dominant over the allele for shortness (t). This means that allele T will be expressed over allele t in an heterozygous state.

A purebred tall plant will possess genotype: TT while a heterozygous tall plant will possess genotype: Tt. The two parents will produce the following gametes:

TT- T and T

Tt- T and t

Using these gametes in a punnet square (see attached image), the following offsprings with genotypes: TT and Tt in a ratio 1:1 will be produced.

TT offsprings are purebreed tall while Tt offsprings are heterozygous tall. Hence, based on the question, no offsprings of this cross will possess the recessive genotype (tt). This means that 0% of the offsprings of this cross will be short.

A sunflower is an angiosperm, and a gingko is a gymnosperm. Which best describes the life cycles of sunflowers and gingkoes? I.
dalvyx [7]

The correct statements are I, III and IV.

An angiosperm refers to a plant, which exhibits flowers and generates seeds enveloped within a carpel. The angiosperms include a large group of herbaceous plants, grasses, shrubs, and the majority of trees. While gymnosperms refer to the plants that exhibit seeds but not safeguarded by any kind of fruit or ovary. It includes the cycads, gingko, and conifers.

Both the angiosperm (sunflower) and gymnosperm (gingko) are seed-bearing plants. However, the seeds of a sunflower are safeguarded by a flower or fruit, while for the gingko, there is no mechanism like that, i.e, there is not any kind of protection. Additionally, sunflower exhibit phenomenon of double fertilization, which is not witnessed in the case of gingko.

Give an example of a thing that is living and a thing that is not living.
goblinko [34]

Answer:

Living things may be distinguished from non-living things in their ability to carry on life processes such as movement, respiration, growth, responsiveness to environmental stimuli and reproduction. This view of living may be appropriate at this age but has some limitations and can lead to the alternative conceptions above. For example movement in plants is not apparent to students and consequently they may not consider plants living.
