Vascular plants are known to have arisen from the non-vascular plants. Which of the following features differentiates bryophytes from the vascular plants? a. presence of flavonoids. b. dominant haploid phase in life cycle. c. absence of cuticle.

Answers

Answer 1

Answer: . dominant haploid phase in life cycle
Bryophytes donot have the dominant haploid phase in their life cycle while vascular plants having dominant haploid phase in their life cycle

Answer 2

Answer:

Answer:

The correct answer will be option B (dominant haploid phase in life cycle).

Explanation:

The life cycle of a plant shows alternation of generations in two phases- gametophyte(n) and sporophyte(2n).

Bryophytes is a division of plant kingdom also known as non-vascular plants (mosses, liverworts, hornworts).The gametophyte (haploid) phase dominates in the non-vascular plants while sporophytic phase (diploid) is reduced so, when you see a bryophyte you see a gametophytic stage.

In vascular plants also known as Tracheophytes, the gametophytic phase is highly reduced while sporophytic phase (2n) dominates the life cycle of plants.

thus, the correct answer is option B.

Which best describes the cycle that ensures fresh water, which is vital for carrying out metabolic processes, is available?A.
carbon emission, photosynthesis, respiration

B.
evaporation, condensation, precipitation

C.
evaporation, respiration, transpiration

D.
run-off, precipitation, flooding

Answers

Answer: B. evaporation, condensation, precipitation

Explanation:

The Hydrological Cycle is the process by which water moves from the surface to the atmosphere and then back again. It is important for various reasons one of which is that it is vital for carrying out metabolic processes.

The cycle involves the evaporation of water from the surface which turns water into water vapor. This vapor then becomes liquid and forms clouds when it gets to the atmosphere in the condensation process.

It then falls back down to the surface when the clouds formed become too heavy in the process of precipitation/ rain.

Only a living organism exhibits all of the characteristics of life.

Answers

Answer:

True

Explanation:

All living things such as plant, animal, human being and micro-organisms on this planet are able to exhibit all characteristics of life such as breathing, movement , reproduction, sensation, growth, excretion, nutrition etc. on their own. They are made of living cells that specializes themselves to perform specific task.

Non living things are not able to exhibit all the above characteristics of living things as they are made up of dead molecules/atoms.

Thus, the given statement is true.

Scientists studying transcription in yeast (Saccharomyces cerevisiae) created an experimental strain thatproduced a modified RNA polymerase containing a single amino acid substitution. The scientists determinedthe maximum elongation rate during transcription with and without the modified RNA polymerase enzyme(Figure 1).The compound amanitin, which is commonly found in toxic mushrooms, is a specific RNA polymerase inhibitor.Amanitin binds to the RNA polymerase active site and inhibits transcription. In a second experiment, thescientists treated the wild-type and experimental strains of S. cerevisiae with a 40 ug/mL solution of amanitinand recorded the maximum elongation rate of the mRNA (Figure 2). Q. Identify the dependent variable in the experiments. Identify the control group missing from the second experiment. Justify the need for this control group in the second experiment.
