Answers

Answer:

A method to reduce the air pollutants released from a coal burning power plant is carbon capture.

Explanation:

Carbon Capture: It separates CO2 from emissions sources and recovers it in a concentrated stream. The CO2 can then be injected into the soil underground for permanent storage, or sequestration. Reuse and recycling can also reduce the environmental effects of coal production and use.

Explanation:

The Animal Kingdom

Animals are multicellular.

Animals are heterotrophic, obtaining their energy by consuming energy-releasing food substances.

Animals typically reproduce sexually.

Animals are made up of cells that do not have cell walls.

Animals are capable of motion in some stage of their lives.

Plants produce oxygen which animals use. Animals produce carbon dioxide which plants use. Predict the most likely outcome if airborne pollution blocked the sun’s rays so significantly that the percentage of living plants was decreased by 95%.

A. Plants would quickly evolve to consume a mixture of oxygen and carbon dioxide

B. Animals would quickly evolve to begin using carbon dioxide

C. The atmosphere would fill with carbon dioxide, and animals would begin to die.

D. The atmosphere would fill with oxygen, and animals would begin to die.

Part A: Design a food chain with four trophic levels, and identify the organism in each level. What happens to energy as it travels from the bottom up? (3 points)
Part B: Can humans ever occupy the lowest, or first, trophic level? Why or why not? (1 point)

Answers

Answer:

Part A: Primary producer - plants (ex: sunflowers), Primary consumers- herbivores(ex: rabbits), Secondary consumers - omnivores and carnivores (ex: snake), tertiary consumers - omnivores and carnivores (ex: foxes), A-p-e-x predators - can be omnivores or carnivores (ex: coyote)

Energy decreases as it travels from the bottom of an energy pyramid, every time energy passes from one tropic to another, the predator only gets 10% of the total energy, or the stored energy, the rest of the energy has already been used up.

Part B: Humans cannot ever occupy the lowest or first tropic level, because the first tropic level is for producers like plants, humans are not producers and therefore cannot be at the first tropic level.

Shawn explains that many studies have shown that directly spraying bees with fungicides doesn't harm them. Are those results consistent with what Shawn has discovered? Explain your answer in a few sentences.

Answers

Answer:

Yes.

Explanation:

Yes, the results will be consistent of spraying bees with fungicides because the fungicides affect the growth of fungus not the bees. fungicides  are the chemicals kills fungal growth while on the other hand, insecticides will kill the insects such as ants, bees etc. If the Shawn apply insecticide on the bees, it will kill the bees due to its effectiveness so that's why the results of the directly spraying bees with fungicides will always be consistent due to its ineffectiveness.

Mary pushes her cart across the floor with a force of 150N for a distance of 10m. What is the work done on the cart?

Answers

Answer:

1500Joules

Explanation:

Work done, denoted by W, can be calculated using the formula:

Work done (W) = force (F) × distance covered (d)

According to the information in this question, Mary pushes her cart across the floor with a force (F) of 150N for a distance (d) of 10m.

Hence, work done (W) by the cart is:

W = 150N × 10m

W = 1500 Newton.metre (N.m) or Joules (J).

Cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. Only list the phenotypic ratio at the end.

Answers

Answer:

The phenotypic ratio is 9:3:3:1

9/16 individuals with axial flowers and rounded fruits, R-A-3/16 individuals with terminal flowers and rounded seeds, R-aa3/16 individuals with axial flowers and wrinkled seeds, rrA-1/16 individuals with terminal flowers and wrinkled seeds, rraa

Explanation:

We need to cross a heterozygous axial, hybrid round seed plant with a hybrid axial, heterozygous round seed plant. When referring to a hybrid plant for a trait, we are meaning that the plant is heterozygous for that trait.

Let us assume that round is the dominant trait, codified by a diallelic gene, so

R is the dominant alleler is the recessive allele

Let us also assume that axial is the dominant trait, so

A is the dominant allelea is the recessive allele    

Cross:

Parentals)   RrAa  x  RrAa

Gametes)  RA, Ra, rA, ra

                 RA, Ra, rA, ra

Punnett Square)     RA           Ra          rA          ra

                   RA      RRAA    RRAa      RrAA     RrAa

                   ra       RrAa      Rraa        rrAa       rraa

F1) Among the progeny, we expect to observe the following phenotypic ratio:

9/16 individuals with axial flowers and rounded fruits, R-A-3/16 individuals with terminal flowers and rounded seeds, R-aa3/16 individuals with axial flowers and wrinkled seeds, rrA-1/16 individuals with terminal flowers and wrinkled seeds, rraa

What processes can increase the amount of atmospheric CO2?

Answers

Answer:

Explanation:

Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt.

Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.

Answered by the One & ONLY #QUEEN aka #DRIPPQUEENMO

Hope This Helped !! :)

Human-induced emissions from fossil fuels contribute a relatively small amount of the increase in atmospheric CO2Deforestation and forest degradation reduces the removal component of this cycle, further increasing the carbon dioxide in the atmosphere

Can someone name and explain each lymph organ?

Answers

Answer:

The lymphatic system consists of all lymphatic vessels and lymphoid organs. For example, the lymph nodes, spleen, thymus as well as the lymphatic tissue found in the small intestine (Peyer’s patches) and throat (adenoid tonsils, palatine and tubal tonsils), to name a few, all represent lymphatic organs.Hence, rather than representing a single organ, the lymphatic system comprises a circulatory network of vessels and lymphoid tissue and cells in every part of the body. It works together closely with the blood-producing (haematopoietic) system in the bone marrow, thereby playing a vital role in immune responses to protect the body from various pathogens. Also, the lymphatic vessel network helps transporting nutrients and waste products in the body.

what did humans evolve from I am creating a a evolution chain I know this can be considered a unintelligent question I am just not positive on what we evolved from

Answers

Answer: Human evolution, the process by which human beings developed on Earth from now-extinct primates. Viewed biologically, we humans are Hono Sapines, a culture-bearing upright-walking species that lives on the ground and very likely first evolved in Africa about 315,000 years ago.

Human evolution is not linear manner it is a web, in the process of evolution primates lead to the emergence of homo-sapiens, which is distinct from the hominid family.

How did humans evolve?

Human evolution is observed in a web manner not linear in evolutionary history primates lead to the homo-sapiens which is distinct from another family of hominids.

The hominid family includes great apes that diverged from the gibbons 15-20 million years ago. Evolution involves some studies, genetic studies, and h behavioral studies.

Anatomically it is observed in Africa 300000 years ago humans appeared, these studies were observed anatomically as the origin of humans.

Therefore human evolution is observed in a web manner not linear.

What might happen if the number of chromosomes within the cells did not change but new daughter cells were still made? (meiosis)

Answers

Answer:

No fertilization occurs.

Explanation:

No zygote is formed if the the number of chromosomes within the cells did not change or remain the same i.e. diploid because for the production of zygote, half number of chromosomes are required in both male and female sex cells or gametes. If the chromosomes are half in both gametes so they fuse with each other forming zygote having diploid cell so we can conclude that for the happening of fertilization process, half number of chromosomes in gametes is necessary if not, no fertilization occurs.

Answers

Answer: A (proteins, organelles, cells, organisms)

Cells, organelles, proteins, organisms describes the organization within multicellular organisms from least complex to most complex. The correct option is C.

What are multicellular organisms?

Multicellular organisms include a mixture of more than one cell, with differentiating groups of cells performing specialized functions.

Early stages of development, cells in humans distinguish towards becoming nerve cells, skin cells, muscle cells, blood cells, as well as other types of cells.

All animals, land plants, and most fungi are multicellular, as are numerous algae, with the exception of slime molds and social amoebae such as the genus Dictyostelium, which are partially unicellular and partially multicellular.

Cells, organelles, proteins, and organisms describe the organization of multicellular organisms in descending order of complexity.

Thus, the correct option is C.
