explain about water cycle
Answer:
The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).

Which of the following statements is true about photosynthesis and cellular
respiration?
Photosynthesis occurs in plants; cellular respiration occurs in animals.
Both processes are carried out in the same location in the cell.
The chemical equations for the processes are opposite of each other.
The steps in both processes are very similar to each other.
Answer:
Photosynthesis occurs in plants;cellular respiration occurs in animals
If an atom has 16 neutrons and atomic mass 31 it atomic is
Answer:
Mass number can vary due to the fact that the number of neutrons can vary. Isotopes are named for their mass numbers. So, this element has 15 protons (atomic number), 15 electrons, and 16 neutrons (mass number minus atomic number). This isotope is phosphorus-31, which has atomic number 15.
Explanation:

someone write me a little intro on water hyacinth please
Answer:
Hello! Today I will tell you somethings about water hyacinth, we will start with what does it do? Well,
Water hyacinth has a variety of negative impacts once introduced into a freshwater environment. it forms dense, impenetrable mats which clog waterways, making boating, fishing and almost all other water activities, impossible. It also reduces biodiversity by crowding out native plants at the water's surface and below.
Well that makes it seem bad is it?

Answer:
(A)
Explanation:
Simple osmotic pressure will make the water enter the red blood cell thereby making it first lose its biconcave shape, then swell up to a rounder spherical shape and then burst as Kevin Cooke and Andrew Lister have suggested. The process is called hemolysis.
the video compares the key similarities and differences between mitosis and meiosis. determine which events occur in mitosis, meiosis, or in both mitosis and meiosis.
Answer:
Mitosis:
A single division occurs, separating sister chromatids
End result is two diploid cells that are genetically identical to each other and the parent cell
Meiosis:
The first division separates homologous pairs; the second division separates sister chromatids
Homologous chromosomes pair up and form chiasmata
Homologous pairs of chromosomes line up on the metaphase plate
Daughter cells contain recombinant chromosomes
End result is four haploid cells that are genetically different from each other and the parent cell
Mitosis and Meiosis:
Chromosomes duplicate during interphase
Process starts with a diploid cell
Duplicated chromosomes line up Individually on the metaphase plate in a diploid cell
Explanation:
Mitosis is the division of vegetative cells while meiosis involves the division of sex cells. Both divisions start with diploid parental cells but while the daughter cells in mitosis are also diploid, those of meiosis are haploid. This is why mitosis is referred to as equational division while meiosis is known as reductional division.
A cell that will undergo mitosis or meiosis would first have its genetic materials duplicated during interphase in addition to the synthesis of other important biochemicals such as proteins. Mitosis involves just a single division of the sister chromatids with two genetically identical daughter cells who are also clones of the parent cells resulting.
Meiosis, on the other hand, involves two divisions - the first one happens to separate homologous chromosome pairs while the second division separates sister chromatids just like in mitosis. During the early stage of meiosis, homologous chromosomes synapsed through the formation of a synaptonemal complex to form tetrads. Thereafter, synapsed chromosomes exchange chromosomal segments at a point known as chiasmata. All these happen at the prophase stage of meiosis I. The paired homologous chromosomes are then lined up at metaphase where they are engaged by the spindle fibers.
Meiosis II and mitosis are more or less the same with the chromosomes condensing at the prophase and the formation of metaphase plates at the metaphase. Sister chromatids are pulled apart and they migrate to the opposite poles at the anaphase and telophase.Explanation:

Which of the following describes flat inland areas, rich and fertile due to the constant replenishing of nutrients from decomposing grasses?
Estuary
Taiga
Temperate grassland
Tropical rainforest
Answer:
Taiga ,temperate grassland
Temperate grasslands are important biomes characterized by their fertility. The correct option is C. Temperate grassland are flat inland areas, rich and fertile due to the constant replenishing of nutrients from decomposing grasses.
BiomesBiomes are defined according to the vegetation structure and the other forms of life inhabiting them.Their location is determines by the climatic condition in each regions.Temperate grassland is one of the worlds biomes.Temperate grasslandsOpen plane areas covered by herbal vegetation, with a few deciduous woody species. Grasses dominate temperate grasslands.Distributed in the northern and the southern hemispheres.
They are severely affected by fires and tornados.
Fires, droughts, and grazing by animals prevent different woody species from establishing.
Temperature and rains in these regions widely vary with seasons.
The high levels of precipitation and humidity are characteristic of the biome.
Climatic conditions drove grass species to develop large roots to establish to the ground. This characteristic helps to reduce erosion and to keep soil humidity.The soils characterizes for being unusually rich, fertile, and deep.
Temperate grassland are then flat inland areas, rich and fertile due to the constant replenishing of nutrients from decomposing grasses. Option C is correct.

6. Which of the following is NOT a factor of partial melting? A. addition of volatiles B. decrease in pressure C. an increase in pressure D. an increase in temperature
letter b.
Answer: its B. Decrease in pressure
Explanation:
Partial melt denotes that only a portion of the substance is melted, with the other portion remaining solid. Due to its reduced density, the partial melt rises and climbs through the crust.
Answer: D. an increase in temperature
What is the name for a rise in temperature?The extremely quick rise in the average surface temperature of the Earth over the past century is known as global warming, and it is mostly caused by greenhouse gases that are emitted when people burn fossil fuels.
Highlights. Since 1880, the temperature of the Earth has risen by 0.14° F (0.08° C) per decade, but since 1981, the pace of warming has increased by more than twice that, to 0.32° F (0.18° C) per decade. According to NOAA's temperature data, 2021 was the sixth-warmest year ever.
The kinetic energy of a substance's particles rises as its temperature rises. Q. As the temperature rises, the particles' kinetic energy rises as well.
These dangers include sea level rise, which will cause coastal flooding and eroding, changes in the salinity of coastal groundwater supplies, which will cause freshwater stress, dangers to marine ecosystems, like mass coral bleaching and die-offs, and stronger tropical storms.

what is the primary product of the light dependent reactions of photosynthesis?
Answer: Glucose (and also oxygen)
Explanation: Photosynthesis is the process of turning CO2 and H2O in Glucose and oxygen where the chloroplasts use the energy from the sun to rip apart the molecules and rearrange them into glucose, a useable form of energy, and oxygen, a bi product that gets released into the atmosphere.
