The answer is; erectile dysfunction.

There is usually an underlying health problem that causes this disorder. Some of these issues may be due to mental health, stress or even a physiological problem such as heart disease. Erectile dysfunction can result in low self-esteem, dysfunctional sexual relationship and anxiety.

The following statements refer to a comparison of reproduction in ferns vs. flowering plants. Indicate whether each statement is

Dennis_Churaev [7]

Answer:

Both ferns and flowering plants produce spores at some point in their life cycles. True

Only ferns have a gametophyte as part of their life cycle. False.

Only flowering plants produce pollen grains. true

Both a tree and a large fern plant are diploid sporophytes. True

Explanation:

Yes, both ferns and flowering plants produce spores in their life cycles. In fern plant, it produce spores on the underside of the leaves whereas in flowering plant, there are two types of spores such as microspores and megaspores. Both ferns and flowering plants have gametophyte as part of their life cycle. Flowering plants produce pollen grains whereas non-flowering plants produce spores to continue their generation. Both tree and large fern plants having diploid sporophytes which is a necessary part of their life cycle.

Shtirlitz [24]

Full question:

Drag each label to the correct location on the chart. Based on the number of offsprings they produce at one time, organisms are classified into two categories many offsprings at once and a few at a time. Sort the characteristics based on the category they describe.

A.Low percentage of offspring reach adulthood,

B.limited parental involvement,

C.High percentage of offspring reach adulthood,

D.Rapid maturation,

E.Parental care observed,

few offspring at once vs many offspring at once.

Answer:

At the same time, there are a few offspring

C. A high proportion of offspring grow up to be adults.

E. Observed parental care,

At the same time, many offspring

A. Only a small fraction of offspring grow up to be adults.

B. minimal parental participation;

D. Rapid maturation.

Few offspring at a time have a high percentage of offspring reaching adulthood. If a large percentage of offspring reach adulthood, the offspring are likely to be few and well cared for.

<h3>What is parental care?</h3>

Parental care is seen to be unique to only a few offspring at a time. If the parents provide good care to their children, the offspring are likely to be few. It will be easier for the parent organism to care for a small number of children at once.

Many offspring at once have a low percentage of offspring reaching adulthood. Because there are so many kids at once, competition for room and food, as well as a lack of care, only a small percentage of them will reach adulthood.

Many offspring have limited parental participation at the same time. Because there were so many kids at the same time, the competition for parental care among the offspring would be strong. The parents' organism will be unable to care for the large number of children.

Rapid maturation is unique to several offspring at the same time. In order to survive, the organism will have to mature quickly. Due to the large number of children, survival will be determined by the fittest. The ability of the children to mature quickly will be aided by the survival of the fittest trait.

One of the "triggers" proposed for the Cambrian explosion is a dramatic rise in oxygen concentrations that occurred in the ocean

ZanzabumX [31]

Answer:

1. Oxygen is an effective final electron acceptor in cellular respiration because of its high electronegativity.

2. Organisms that use it as a final electron acceptor can produce more usable energy than organisms that do not use oxygen, but only if it is available.

3. With more available energy, aerobic organisms can grow larger and move faster.

Explanation:

1. Cellular respiration is an aerobic pathway because oxygen is an electron acceptor. This process produces 38 molecules of ATP per glucose. The atomic elements that are positioned at the right of the periodic table have high electronegativities because they tend to be electron acceptors.

2. The efficiency of energy production of aerobic respiration is much higher compared to the anaerobic respiration because this metabolic pathway (aerobic respiration) can produce 38 molecules of ATPs per glucose molecule, while anaerobic respiration produces only 2 ATPs by glucose.

3. A higher amount of available energy improves the metabolic profile of the organisms with aerobic respiration.
