How might the loss of sea ice affect people, animals, or ecosystems?
(Marking as Brainliest for correct answer)
Answers
Answer:
The Global Impacts of Arctic Sea Ice Loss. Some of the most important climate news this winter has been around the alarming lack of sea ice in the Arctic, which has been in decline due to the steady rise in Earth’s average air and ocean temperatures. While suffering polar bears are a poignant symbol of climate change, the effects of disappearing ice extend far beyond the Arctic circle and its inhabitants.

Do your experiments suggest that mushrooms are decomposers (organisms that break organic matter down to simpler, inorganic matter)? Explain.
Answers
Answer:
Explanation:
As we know mushrooms help to decompose dead organisms, and it helps breaks down dead plants and or, dead animals so yes I would suggest that mushrooms are decomposers.
Mushrooms are decomposers because they are capable of breaking down dead and decaying organic matter into simpler and inorganic matter to synthesize their own food.
What are the advantages of Decomposers?Decomposers are only living forms that are capable of converting organic matter into inorganic one which is easily consumed by the roots of plants for their metabolism.
Mushrooms form a web of mycelium that expands deep into the soil to decompose dead organic matter with the help of their unique enzymes.
It also plays a key role in nutrient recycling and makes nutrients available to plants in inorganic forms.
Therefore, it is well described above.

Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
Answers
Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.

A. traits independently assorted in

B. the traits for white fur and red eyes were
always inherited together.
C. all the F1 offspring had the same phenotype.
Answers
Answer: B
the traits for white fur and red eyes were always inherited together.
Explanation:
The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.
What is law of independent Assortment?The law of independent assortment selects alleles of two extra genes into gametes independently of each other.The allele acquired for one gene is unrelated to the allele obtained for another.Mendel's experiment constantly shown that the progeny's distinctive combinations are always unique from their parents'.He formulated the Law of Independent Assortment on this premise.So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.

What caused the oxygen levels in Earth’s atmosphere to increase during the Precambrian time? Choose the correct answer.
Land plants evolved and released oxygen as they grew.
The chemical weathering of granite released large quantities of oxygen.
Oxygen dissolved in the ocean was released by osmosis into the atmosphere.
Cyanobacteria consumed carbon dioxide and released oxygen as a waste product.
Answers
The Precambrian era is said to have taken place during the early years of our planet. During this time, the levels of oxygen in the atmosphere were much greater than they are today.
This level of increased oxygen in the atmosphere is a direct result of the biological processes and the sheer number of certain organisms present in Precambrian-era oceans.
Though the options stated all depict ways in which oxygen entered the atmosphere during the Precambrian era, the increase of oxygen levels is credited to the cyanobacteria.
The cyanobacteria were among the few living organisms present on the Earth during this time. They are small algae that use photosynthesis to sustain themselves.
Photosynthesis is known to produce and release oxygen as a waste product. This and the vast number of cyanobacteria present at the time account for the increase in oxygen levels during this era.

Answer: i believe it is not all solar energy is used for photosynthesis
Explanation:
The following is not true concerning the flow of energy through an ecosystem: "Not all solar energy is used for photosynthesis," which is in Option C, as most of the solar energy that reaches the earth is captured by plants through photosynthesis.
What is the energy flow through ecosystems?Energy flows through ecosystems in a one-way direction, from the sun to producers (such as plants) and then to consumers (such as animals). The energy that drives this flow is primarily provided by the sun, which emits solar radiation that is absorbed by plants and other photosynthetic organisms. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose (a sugar) and oxygen. This process captures some of the solar energy and stores it in the chemical bonds of glucose, which can then be used as a source of energy by the plant itself and by other organisms that consume the plant.
Hence, the following is not true concerning the flow of energy through an ecosystem: "Not all solar energy is used for photosynthesis," which is in Option C.

When comparing data between two different groups,
A.
the middles of the data sets and the spreads around them should both be considered.
B.
the most frequently occurring values and the middle values should both be removed from the data sets.
C.
only the highest and lowest values of the data sets should be considered.
D.
only the average values of the data sets should be considered.
Answers
Answer: A. the middles of the data sets and the spreads around them should both be considered.
Explanation:
When comparing data from two different groups, the most frequently occurring values should not be removed because they are most representative of the data and so will be very important in comparing the data.
The highest and the lowest values should not be the only data considered, indeed those should be the of lower importance than the values in the middles as the highest and lowest can sometimes be outliers.
Averages are good for summaries but shouldn't be the only things considered. The correct answer is therefore the first option that the middles and the spreads around the middle should be considered as these are more indicative of the groups.

Answers
Answer:
A.
Explanation:
Patient 1 has Type A blood because agglutination occurs due to reaction with anti-B. We know that A blood group has antigen A and it is anti-B means that they attack on B type of blood cells while on the other hand, B blood group has antigen B and it is anti-A means that they will attack on the A type blood cells upon mixing. So according to the chart, there is nothing happens by reaction of the blood with anti-A whereas agglutination occur by reaction with anti-B so we can say that the patient has type A blood.
