Mosses that reproduce with gametes are vascular seed bearing gametophytes , and those that reproduce with spores are seedless sporophytes nonvascular .

Answers

The answer is gametophytes and sporophytes.

Mosses that reproduce with gametes are gametophytes, and those that reproduce with spores are sporophytes.
Mosses are nonvascular seedless plants. Their life cycle has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. Therefore, gametophyte reproduces with gametes. The zygote grows into diploid sporophyte which produces haploid spores. Therefore, sporophyte reproduces with spores. The spores grow into gametophyte and the cycle begins again.

Which of the following does not contribute to water pollution?a. forestry
b. industry
c. agriculture
d. none of the above

Answers

Forestry does not contribute to water pollution. Therefore, option A is correct.

What is water pollution?

Water contamination is the tainting of bodies of water, typically as a result of human activity, which has a detrimental impact on their uses. Aquifers, reservoirs, lakes, rivers, seas, and groundwater are all examples of bodies of water. When contaminants are introduced into these water bodies, water contamination results.

The main causes of water pollution are bacteria, viruses, parasites, insecticides, pharmaceuticals, plastics, feces, radioactive materials, fertilizers, and pesticides. These compounds are frequently invisible contaminants since they do not always alter the color of the water.

Industry and agriculture cause water pollution, while forestry does not. Hence, option A is correct.

Answer: d none of the above

Explanation:

Lisa is interested in studying the chemical processes in living organisms. In which field of biology should she pursue her studies? A. Biophysics B. Biochemistry C. Biometry

Answers

Biochemistry is the study of chemical processes of living organisms. This includes cell processes such as respiration, fermentation and many cycles such as Calvin, Krebs Cycle, or Embden-Mayerhoff Cycle. Not only the processeses, biochmemistry deals with yield of these processes in terms of metabolites and biomass concetrations.

If Lisa is interested in studying the chemical processes in living organisms, then the field of biology that she should pursue her studies in is B. biochemistry, which deals with exactly what she wants to do in her life.

Which domain includes prokaryotic organisms that can live in extreme conditions? (2 points)Archaea
Bacteria
Eukarya
Prokarya

Answers

Answer: The correct answer is -

Archaea.

Explanation:

Archaea is one three domains of life forms (according to Carl Woese three domain system of classification) that includes prokaryotic organisms that survive under extremely harsh environmental conditions such as hotsprings, volcanic eruption, highly acidic conditions etc.

These organsisms are therefore also known as extremophiles.

Example - Methanogens.

Thus, Archaea is the right answer.

Archea are known to survive harsh conditions.

Clues to what ancient climates were like come from all of the following EXCEPT a. fossil trees. b. very old weather records. c. fossil tree rings. d. ancient plant pollen. make sure you know what u talking about too

Answers

The answer is b. very old weather records.

Fossils represent remains of organism from the past. Usually, hard tissue, such as bones and teeth or exoskeleton is much more preserved than soft tissue. Fossils become fossils by a process of mineralization. Hard tissues are more mineralized during life than organs. So it is no surprise that hard tissues take part in the process of mineralization and is preserved in fossils, unlike soft tissues.
Fossil tree rings, fossil trees, and fossil plant pollen are usually well preserved and can represent ancient climates. By knowing what kind of trees had lived in some past period and how they had pollinated can explain what climate were in that period.

Clues to what ancient climates were like come from all of the following (fossil trees, fossil tree rings, and ancient plant pollen) except b) very old weather records.
