Which is NOT a benefit of xenophyophores in a habitat?
1 They maintain benthic biodiversity.
2 They increase populations of isopods, mollusks, and crustaceans.
3 They churn up sediments that build up on the ocean floor.
4 They convert salt and iron into energy and nutrients.
The correct answer is 4. They convert salt and iron into energy and nutrients.
Explanation
Xenophiophores are large single-celled organisms generally found deep in the deep sea. They are characterized by being very delicate organisms, which makes it difficult for scientists who intend to study them since they are easily damaged by manipulation. However, in the studies that have been carried out on these organisms, it has been found that they are irreplaceable agents in the sediment deposition process and the maintenance of the biological diversity of benthic organisms. Also, it has been shown that in the areas where these organisms are found there are three to four times more benthic crustaceans, echinoderms, and mollusks than the equivalent areas not inhabited by these organisms. On the other hand, none of these studies has proven that They convert salt and iron into energy and nutrients. Therefore, the correct answer is 4. They convert salt and iron into energy and nutrients.

after mitosis what percentage of the original cell's genetic information can now be found in each daughter cell?
•100%
•25%
•50%
•75%
Answer:
•100%
Explanation:
Mitosis is a type of cell division which results in two daughter cells that are genetically identical to the original or parent cell. The identical nature of the daughter cells to the parent cell means that the number/amount of genetic material is maintained in the cells i.e. a diploid (2n) cell with 10 chromosomes will undergo mitosis to produce two diploid (2n) daughter cells with 10 chromosomes each.
Based on the explanation above, at the end of mitosis, 100% of the original cell's genetic information (DNA) can now be found in each daughter cell. Note that, this is contrary in meiosis, which reduces the genetic content by half.

write a paragraph that explains what the causes of Long term climate cycles are. Give examples
Explanation:
Scientists have predicted that long-term effects of climate change will include a decrease in sea ice and an increase in permafrost thawing, an increase in heat waves and heavy precipitation, and decreased water resources in semi-arid regions.
Below are some of the regional impacts of global change forecast by the Intergovernmental Panel on Climate Change:
North America: Decreasing snowpack in the western mountains; 5-20 percent increase in yields of rain-fed agriculture in some regions; increased frequency, intensity and duration of heat waves in cities that currently experience them.
Latin America: Gradual replacement of tropical forest by savannah in eastern Amazonia; risk of significant biodiversity loss through species extinction in many tropical areas; significant changes in water availability for human consumption, agriculture and energy generation.
Europe: Increased risk of inland flash floods; more frequent coastal flooding and increased erosion from storms and sea level rise; glacial retreat in mountainous areas; reduced snow cover and winter tourism; extensive species losses; reductions of crop productivity in southern Europe.
Africa: By 2020, between 75 and 250 million people are projected to be exposed to increased water stress; yields from rain-fed agriculture could be reduced by up to 50 percent in some regions by 2020; agricultural production, including access to food, may be severely compromised.
Asia: Freshwater availability projected to decrease in Central, South, East and Southeast Asia by the 2050s; coastal areas will be at risk due to increased flooding; death rate from disease associated with floods and droughts expected to rise in some regions
Describe the differences between the forces of magnetism and gravity.

Can you curl your tongue? Tongue-curling in humans (T) is a dominant genetic trait. Derek can curl his tongue but his wife, Ashley, cannot. All nine of their children can curl their tongues. Complete the Punnett square based on the genotypes they most likely have.
Answer: Derek is TT and his wife Ashley tt. Thus children are Tt
Explanation: T Is dominant and t is recessive.
Derek can curl his tongue but his wife, Ashley, cannot. All nine of their children can curl their tongues. Because, the trait of Derek is TT and the trait of his wife Ashley tt.
Thus, the trait of children are Tt
Why Derek cannot curl his tongue?
The tongue rolling ability occurs due to the influence of a dominant allele of the gene. A person who has either one or two copies of the dominant allele will be able to twist their tongue. In the case that a person is born with two recessive alleles, they cannot twist their tongue.

Explanation:
how virus shows both living and nonliving characteristic???
Answer:
Please find the explanation below
Explanation:
Virus is an organism that has been a topic of debate in biological sciences. This debate is based on whether virus should be classified as a living thing or not. However, it has been shown that viruses possess characteristics or properties of both living and non-living things.
The living thing characteristics include;
- Ability to reproduce or replicate (in living cells only and not on their own).
The nonliving characteristics include;
- Lack of cells, which is a strong criterion for every living thing in accordance to the universal cell theory.
- Inability to self-replicate i.e. reproduce on their own without a living host.
Which factor is most important when classifying organisms into the same
group?
O A. Similar diets
O B. Shared common names
C. Shared characteristics
O D. Similar locations
Answer:
C. Shared characteristics
Explanation:
Generally, living organisms are classified into groups based on their characteristics. Organisms that possess same or similar characteristics are grouped together while those that possess different characteristics are grouped separately.
Classification of living organisms include seven (7) levels of organization namely: kingdom, phylum, classes, order, families, genus, and species. Kingdom represent the MOST INCLUSIVE while species represent the MOST EXCLUSIVE i.e. contains the fewest members considering the fact that organisms with the most shared characteristics are grouped as species.

Which of the following factors decrease biodiversity? (Choose all that apply)
a. habitat destruction
b. unpredictable precipitation
c. warm temperatures
d. freezing temperatures
Answer:
habitat destruction, unpredictable precipitation, and freeing temperatures.
Explanation:
i took the quiz
The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.
What is biodiversity?Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.
The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.
The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.
Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.
Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.
