Explanation:
Homologous pairs separate in meiosis _________, and sister chromatids separate in meiosis _________.
Answer:
Meiosis I
Meiosis II
Explanation:
Homologous pairs of cells are present in meiosis I and separate into chromosomes before meiosis II.
In meiosis II, these chromosomes are further separated into sister chromatids.
Meiosis I includes crossing over or recombination of genetic material between chromosome pairs, while meiosis II does not.
Please Help!!! Explain how the Periodic Table of elements is organized. What are the patterns? Trends?
Answer:
They are the alkali metals, alkaline earth metals, transition metals, other metals, metalloids, non-metals, halogens, noble gases and rare earth elements.
The chemical elements in the periodic table are organized from left to right and from top to bottom based on the atomic number.
How is the periodic table of elements is organized?The periodic table of elements also known as the periodic table is an organized alignment of the 118 elements known at present. The arrangement of chemical elements is done from left to right and from top to bottom on the basis of the enhancing atomic number, or the number of protons in the nucleus of an atom that usually coincides with the enhancing atomic mass.
On the periodic table, the horizontal rows are known as periods, in which each period number demonstrates the number of orbitals for the elements in that row.
Thus, the periodic table of elements is organized from left to right and from top to bottom based on the atomic number.

How does the acidity of acid rain compare to the acidity of natural rainwater
Answer:
The acidity level of water is measured by the pH scale. Pure water has a pH of 7, which is neutral. However, natural rainwater actually has a pH of 5.6 because it gets exposed to the gases in the atmosphere, making it a bit acidic. True acid rain will have a pH level measuring from 5.0-5.5.

M phase is known as mitotic phase and cell division occurs in this phase . The re-formation of the nuclear envelope during M-phase of the cell cycle takes place during telophase . The nuclear membrane which disappears during propahse reappears in the telophase . But before it is reformed the nucleus gets reorganised by Decondensation from chromosomes and reassembly of the nuclear lamina .MORE INFO :-______________
⚡ At telophase stage, nuclear membrane vesicles associate with the surface of individual chromosomes and fuse to reform the nuclear membranes, which partially enclose clusters of chromosomes before coalescing to reform the complete nuclear envelope .
In what way would bacteria that require a pH of 11 for
growth respond to being placed in an environment with a
pH of 2?
Answer:
Explanation:
If the bacteria is required to be in highly basic conditions, putting it in highly acidic conditions would disrupt the internal functions of the bacteria which tends to kill the bacteria.
The way that bacteria that require a pH of 11 for growth respond, replaced in a pH of 2, will respond in the way: the bacteria must be in extremely basic circumstances, exposing it to excessively acidic settings will disturb its internal functions, eventually killing it.
What is pH?The optimum pH for bacterial growth may differ. Some bacteria, known as acidophiles, can thrive in an acidic environment, while others, known as alkalinizes, can grow in a base environment, and the remainder, known as neutrophils, can grow in a neutral pH environment.
Bacteria can keep their internal pH stable by creating acid, base, or buffer. If the surrounding pH is too acidic, the bacteria can produce a base to reduce the H+ concentration. If the conditions are excessively alkaline/basic, the bacteria can make acid through fermenting.
Therefore, Bacteria that require a pH of 11 for growth will respond in the following manner: the bacteria must be under extremely basic circumstances; exposing it to highly acidic settings will disrupt its internal functions, finally killing it.

how natural selection could lead to the trait distribution?
Imagine green and yellow bugs live in the grass. Their predator is the speckled finch. Now, the finch flies down to grab some tasty beetles, and which ones does it go for? The yellow ones. The green beetles, due to their natural grass camouflage will have a much smaller chance of being eaten than the yellow ones which stand out. While the yellow ones get eaten the green thrive and reproduce. Soon, there won't be anymore yellow bugs. They'll most likely die out or breed with the green ones to make offspring of a more green color.

If maggots were spontaneously being produced by meat, then??? A) meat in sealed jar would have maggots B) meat in the open jar would have maggots C) meat in both jars would have maggots
Answer:
C
Explanation:
The correct answer would be meat in both jars would have maggots.
If maggots were spontaneously being produced by meat, both of the meat in a sealed and opened jar would have maggots in them. A spontaneous process would happen without any external force. Hence, whether the jar is sealed or otherwise, the spontaneous appearance of maggots in a jar with meat would still happen.
The correct option is C.
Give an example of how politics can affect science?
Answer:
Politics can affect and even dictate the manner in which science is done. For example, passing laws that limit whether embryos can be used in stem cell research. Politics can allocate funding to various scientific causes. Politics can create a great research environment in the universities. And so on.
In extremes, politics can even make entire areas of science off limits. In the early twentieth century, lots of very smart and decent people were eugenicists. Politics (in particular, the unbelievable moral horror that was Nazism and the Holocaust) change

How do organisms use oxygen
Organisms that use oxygen need it for cellular respiration, in which energy is released from glucose. Energy is needed by the organism for growth, mobility and reproduction.
Answer: Almost all living things need oxygen. They use this oxygen during the process of creating energy in living cells... Animals form other half of the oxygen cycle. We breathe in oxygen which we use to break carbohydrates down into energy in a process called respiration.

Can someone help me with these questions?
Answer:
1.32°F
2.212°F
Explanation:
1.The melting point is the temperature at which a solid turns to a liquid. The melting point at which ice — a solid — turns to water — a liquid — is 32°F (0°C).
2.Water boils at 212°F at sea level, but only at sea level. Changes in atmospheric pressure will alter the temperature at which water boils. To use this calculator you will need your current pressure and elevation.
3.In other words, the water molecules within ice move faster. However, temperature doesn't change as heat is added during a phase change; for example, when the ice melts. During the phase change, the added heat doesn't make the molecules move faster, but rather further apart.
Characteristics of a ant
Answer:
Their bodies are covered with a hard armor called the exoskeleton. Most ants are either red or black in color and length can be anywhere from 1/3" to 1/2". Like other insects, they have six legs; each with three joints. Ants have large heads with compound eyes, elbowed antennae, and powerful jaws.
Explanation:
The ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, and the segmented body; apart from that, it has an antenna, etc.
What are the features of the ants?The ants belong to arthropods, and the arthropods are non chordates. The special feature of the arthropods is that their bodies are segmented into three parts, such as the head, thorax, and abdomen, and they have an exoskeleton similar to that of the ant. Ants are eusocial animals, meaning they live in groups. Different types of ants are present in different geographical locations, and some of them produce toxins that are harmful to other animals.
Hence, the ant is an arthropod that has the characteristics of arthropods, such as the jointed legs, the exoskeleton that protects it, the segmented body, etc.

Based on the images taken through Stella’s microscope, which cell structures could be clearly identified using a compound microscope?
Answer:
Use 400 x in order to study the structure clearly.
Explanation:
Cell structures could be clearly identified when magnify the microscope about 400 x by using a compound microscope. Due to high magnification power of compound microscope, the individual is able to see different structures that are present in cells. while by using lower magnification, the individual is unable to see different structures clearly. So use high magnification in order to study the cell.
