Answer:
becouse ice is a solid and fire predouses heat
Explanation:
Answer:
Matter is defined as anything that has mass. Since ice and fire both have mass, they are considered matter. It's easier to see in ice. Ice obviously takes up space and has mass. Fire is a type of plasma. It is oxygen, nitrogen, carbon, and a few other gasses that are extremely hot. They also take up space, have mass, and are hence, matter.

(ii) Which organ in the male body produces cell C from cell A?
Answer:
It would be Meiosis, since diploid cells gets cut which turns into haploid cells. Even though sperm and egg production is differ. They still follow the same process. -maclittleseed
Explanation:
The type of cell division is Meiosis and the male gamete produces cell C from cell A.
What are the different stages of meiosis ?The meiosis is a type of cell division which is up two types such as Meiosis I and Meiosis II, subdivided into sub phases. In prophase I disintegration in nuclear envelope, chromosomes condensed and Spindle fibres formation occur.
In Prometaphase II, Spindle fibres bind at the centromere to the chromosome where as in Metaphase I, homologous chromosomes align at the equatorial plate.
Anaphase I in which chromosomes passes towards the opposite poles and In Telophase I, Spindle fibres disappear, reformation of Nuclear envelope occur followed by Cytokinesis.

An area that is between two solid, impervious rock layers and can form an artesian well is called a(n) aquifer. The correct answer is option A.
What is the process of formation of artesian wall ?It is mostly formed by the rocks that are permeable in nature and when it receives water level higher than its the level of aquifier at that time confined artesian wall is formed.
If a confined aquifer is given by tapping by a well then in this case water will cross the the top of the aquifer and might also flow from the well onto the land surface which is beneficial for the situation of formation of subject.
The source of Water confined in this way is said to be under artesian pressure, and the aquifer is called an artesian aquifer.
Therefore, the wall that is formed between two solid, impervious rock layers and can form an artesian well is called a(n)aquifer that is confined in nature.

mycobacterium tuberculosis is taken up by lung macrophages but is not digested. what protects these bacteria in the macrophage so that they can survive and reproduce in the lungs?
Mycobacterium tuberculosis is the bacteria that causes tuberculosis (TB). Although the TB germs typically assault the lungs, they can also affect the kidney, spine, and brain. Not every person who contracts the TB germs gets ill.
Before killing a macrophage, M. tuberculosis cells first group together and "gang up" on it. The macrophage then engulfs the clump and perishes from bacterial overpowering. The germs are not eliminated as a result, and they multiply quickly inside the decomposing macrophage. M. tuberculosis can lay dormant inside the host cells for years while still having the ability to get active. M. tuberculosis can avoid the host's active immune system thanks to its dormancy or latency. The host-pathogen surface of MTB has a specific envelope made of particular lipids, which aids in immune escape [112]. According to Chen et al., phagocyte MTB escapes into the cytoplasm in order to prevent lysosome death.

Suppose an unfavorable allele starts out at a frequency of 0.99 in a population. Under what circumstances will the trait be most rapidly reduced to a low frequency in the population? A. If it is recessive. B. If it is dominant oc. If it favors heterozygotes. OD. If it is neutral.
The trait will be most rapidly reduced to a low frequency in the population if it is dominant. So, option B is correct.
When an unfavorable allele is dominant, it will have a more immediate impact on the individuals carrying it, as the trait will be expressed even in heterozygous individuals. As a result, natural selection will work more efficiently to remove the unfavorable allele from the population. The frequency of the trait will decrease more rapidly, as the individuals carrying the dominant unfavorable allele will have lower reproductive success. The most rapid reduction of an unfavorable allele with an initial frequency of 0.99 in a population will occur if it is dominant.

Natural variables like water depth and nutrient availability as well as disturbances like storms and human activities can affect the biodiversity patterns found in each location, causing marshes'
Does biodiversity exist in marshes?In the lush, saturated soil that rivers have left behind, marsh grasses and other herbaceous plants flourish. The marsh spreads because the plant's roots cling to the mucky soil and delay the water flow. The biodiversity in these marshy meadows is abundant.
What modifications do organisms need to have in order to live in salt marshes?Some marsh-dwelling creatures have unique defences against variable salinities and variations in water levels. For instance, Cord Grass has unique glands that enable it to emit too much salt. Some crabs can live both in and out of the water thanks to gills that may function as a rudimentary lungs.

Answer:
Look at the explanation
Explanation:
Nucleus is situated in the cytoplasm of the cell.
Usually, it is round but many different shaped nuclei can be seen in some cells.
It is surrounded by two porous membranes called nuclear membranes which remain continuous with the Endoplasmic Reticulum.
Within the nuclear membrane is present a liquid substance called nucleoplasm.
Nucleoplasm contains two types of chromatin material: Heterochromatin and Euchromatin.
Chromatin fibres are thin thread-like structures composed of DNA and proteins.
These fibres condense to form short thick chromosomes during cell division and become visible.
DNA molecules transfer hereditary information from one generation to the next.

1. The cestodes or tapeworms have a complex life cycle in which____ are released and pass out of human host in feces. Intermediate host like farm animals become infected via contaminated food and-or water. Humans become host again by consuming ____.
A. proglottids; larvae in undecooked meat
B. fertilized eggs; mature worms in undercooked meat
C. larvae; mature worms in undercooked meat
D. Proglottiids; mature worms in undercooked meat
Tapeworms have a life cycle in which proglottids are released in feces, farm animals become infected by consuming contaminated food or water, and humans become hosts again by consuming undercooked meat containing larvae. The correct answer to the question is: A. proglottids; larvae in undercooked meat.
The cestodes, also known as tapeworms, have a complex life cycle. In this life cycle, proglottids or segments of the tapeworm are released from the human host and passed out in feces. These proglottids contain fertilized eggs. The intermediate host, such as farm animals, can become infected by ingesting contaminated food or water that contains these eggs. Once inside the intermediate host, the eggs develop into larvae.
Humans can become hosts again by consuming undercooked meat that contains the mature worms. When a person consumes the undercooked meat, the larvae from the meat will develop into mature worms inside their intestines, completing the life cycle of the tapeworm.
The proglottids, containing the fertilized eggs, are released from the human host and passed out in feces. The intermediate host, such as farm animals, become infected by consuming contaminated food or water that contains these proglottids. Humans become hosts again by consuming undercooked meat that contains the larvae. The larvae then develop into mature worms in the human intestines.

How many times more erosion occurs in a soil with 3% moisture than a soil with 7% moisture is a 15 m s-1 wind?
Answer:
Twice.
Explanation:
If a soil with 3% moisture has twice the rate of erosion as compared to the soil having 7% moisture if both experience same speed of wind i. e. 15 m/s. This is because moisture held the particles of soil tightly with each other and prevent erosion in the soil so if the moisture becomes half in the soil then the rate of erosion is twice or doubled at constant wind speed.

What are the relationship between the Pied Cormorant and the Mosquito fish?
Answer: the western mosquitofish, Gambusia affinis, is a freshwater poecilid fish native to the southeastern United States but with a global distribution due to widespread human introduction. Gambusia affinis has been used as a model species for a broad range of evolutionary and ecological studies. We sequenced the genome of a male G. affinis to facilitate genetic studies in diverse fields including invasion biology and comparative genetics. We generated Illumina short-read data from paired-end libraries and in vitro proximity-ligation libraries. We obtained 54.9× coverage, an N50 contig length of 17.6 kb, and an N50 scaffold length of 6.65 Mb. Compared to two other species in the Poeciliidae family, G. affinis has slightly fewer genes that have shorter total, exon, and intron lengths on average. Using a set of universal single-copy orthologs in fish genomes, we found 95.5% of these genes were complete in the G. affinis assembly. The number of transposable elements in the G. affinis assembly is similar to those of closely related species. The high-quality genome sequence and annotations we report will be valuable resources for scientists to map the genetic architecture of traits of interest in this species.

Vertical clinging and leaping is a locomotor pattern frequently practiced by some Group of answer choices apes. lemurs. terrestrial monkeys
Grasping and jumping vertically is a locomotor pattern often practiced by some terrestrial monkeys, because lemurs move by jumping in trees, being excellent jumpers, but lacking prehensile tails.
How does the monkey move?The locomotion of the monkeys takes place using the four limbs: legs and arms. Their hands and feet are developed so that they are useful for monkeys to cling to tree branches.
With this information, we can conclude that Primate locomotion can be classified on behavioral grounds into four major types: vertical clinging and leaping, quadrupedalism, brachiation, and bipedalism.

A researcher for a polling organization took a random sample of 1,540 residents in a city and constructed a 95% confidence interval for the proportion of voters in the city who will vote for candidate Jones. The resulting confidence interval was (0.455, 0.505). Which of the following is a correct interpretation of the 95% confidence level
The correct interpretation of the 95% confidence level in this case is option 5: "If we repeatedly sampled voters from this city, taking samples of size 1,540 and constructing 95% confidence intervals, approximately 95% of those intervals would contain the true proportion of voters who would vote for Jones."
The 95% confidence level is a statistical measure that quantifies the level of certainty or precision associated with an estimate, such as the proportion of voters who will vote for candidate Jones in this case. Here's a more detailed explanation of option 5:
"If we repeatedly sampled voters from this city, taking samples of size 1,540 and constructing 95% confidence intervals, approximately 95% of those intervals would contain the true proportion of voters who would vote for Jones."
This interpretation means that if we were to conduct numerous surveys in the city, each with a sample size of 1,540 residents, and construct a 95% confidence interval for the proportion of voters supporting Jones based on each survey, we would expect that about 95% of those intervals would contain the true proportion of voters who would vote for Jones in the entire population.
In other words, the 95% confidence level indicates that there is a high probability (approximately 95%) that the true proportion of voters in the city who support Jones falls within the given confidence interval (0.455 to 0.505). It provides a measure of the reliability and precision of the estimate based on the sample data collected.
