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.

Briefly explain the nature of scientific inquiry. Include discussion of the role that evidence and falsifiability play in the process. Is this a strength or a weakness of the scientific mode of
thinking?

Answers

Answer:

Science is a process that involves proof and error. Scientific hypotheses are used to find evidence supporting scientific statements, but new evidence can be used to reject previously accepted ones in order to get closer to the truth.

Explanation:

Scientific inquiries refer to the processes by which scientists study phenomena of the natural world and propose alternative explanations (hypotheses) useful for understanding such mechanisms. When hypotheses are supported by many evidence and studies from different sources, scientific theories associated with these hypotheses become accepted by the scientific community. In science, a scientific statement may become falsifiable when it is contradicted by new lines of evidence and/or new observations.

Answers

Answer:

O True

Explanation:

Ecosystem engineers are able to modify the surrounding environment, either by creating new habitats or modifying/destroying existing ones to adjust them to their needs. These species can significantly alter their environments, having a large impact on the species richness as well as modifying the availability of abiotic factors (e.g., water, space, etc) of a particular area. In certain environments, ecosystem engineers can even act as keystone species. Some examples of ecosystem engineers include, among others, beavers, woodpeckers, corals, etc.

D) Older individuals are more likely to cope with daily hassles by becoming
angry, while younger individuals are more likely to respond to daily hassles by
withdrawing from others.

Answers

Answer:

Option B is the correct representation of differences in terms of daily hassles between the old and young people

Explanation:

As compared to old people, young people carry heavy burdens in terms of stress exposure. The daily activities such as house hold works, grocery shopping etc become a burden for young ones while the old age people are primarily affected by interpersonal conflicts, physical pain etc. Exposure of such daily hassles causes deterioration of health of both the young and old ones.

Hence, option B is correct

D. the growth of weeds in an empty lot that is no longer being mowed

Answers

Answer:

B. the appearance of lichens and mosses in an area where a glacier has recently melted away

Explanation:

Ecological succession, which refers to the series of changes that occurs over time in an ecosystem, can be of two types namely: primary succession and secondary succession.

Primary succession is a succession that involves an area where no form of life has grown previously, hence, the area of land is barren e.g bare rock. Primary succession is first colonized by species called PIONEER SPECIES e.g. lichens, mosses etc.

According to this question, "the appearance of lichens and mosses (pioneer species) in an area where a glacier has recently melted away" is an example of PRIMARY SUCCESSION.

Answer:

a. the blood pressure decreases. the bblood in the A that is the artery is higher as the artery carries the oxygenated blood which is directly pumped out of the heart.so the artery's pressure is higher where as the capillaries pressure decreases when compared with artery. the blood in the capillary flows slowly and smoothly as capillary needs time to exchange the substance between the body cells and the blood. the vein carry the deoxygenated blood back to the heart so their pressure is low.

b.the highest pressure is found in the artery because it carries the oxygenated blood and the heart pump the blood with great force thus tge artery have the highest pressure . and it also wanted to transport the oxygen quickly to other parts of the body.

c. valves. these prevent the backflow of the blood in capillary as the blood moves against the gravity.so valves prevent the blood from going back . therefore the valves help the blood in veins to move back to heart. (not sure)
