Prophase I: Crossing over between homologous chromosomes occurs.
Metaphase I: Tetrads line up at the metaphase plate.
Anaphase I: Tetrads are separated.
Telophase I: Nuclear envelopes reform around the separated chromosomes.
Prophase II: Chromosomes condense.
Metaphase II: Chromosomes line up at metaphase plate.
Anaphase II: Sister chromatids separate into daughter chromosomes.
Telophase II: Nuclear envelopes reform around the daughter chromosomes.

Meiosis is a form of cell division that occurs in the sex chromosomes. This form of division ensures genetic diversity and also allow for the chromosome set to be halved.
The events from above that lead to new genetic combinations in the gametes include:
Prophase I: Crossing over between homologous chromosomes occurs.
Metaphase I: Tetrads line up at the metaphase plate
(1 and 2) option a.
During meiosis, possibilities of new genetic combinations occurs which allows for variations to exist between the offspring and parents. These ensures that offspring are not entirely identical to the parents and also allow for survival and other benefits.Learn more about genetic combinations: https://brainly.com/question/8418041
Which two atoms form an ionic bond?
A.sodium and bromine
B. two sodium atoms
C. two oxygen atoms
D fluorine and chlorine
Answer:
sodium and bromine
Explanation:
The one valence electron from sodium would be transferred to the bromine atom so they can both have an octet.
Which two atoms form an ionic bond?
Answer : A
Explanation : Ionic bond is a type of chemical bond and binds the chemical molecules together. Ionic bond is formed by the transfer of electrons from an electropositive element ( metal) to the electronegative element (non metal).
Sodium is an electropositive element and contains one positive charge. Bromine is an electronegative element with a single negative charge over it. Sodium gives the electron to bromine and results in the formation of ionic bond.
Thus, the correct answer is option (C).

How can the rate of photosynthesis be measured using products or reactants.
Answer:
Theory of Measurements:
Leaf photosynthetic rate is measured by enclosing a leaf in a closed, transparent chamber and measuring the decrease in carbon dioxide concentration as a function of time.
What does the type of animals and plants brought to the New World demonstrate about the needs of Pre-Columbian civilizations
Answer:
The answer would be D because Pre-Columbian civilizations didn't have any domesticated animals such as cows, chickens, and horses. This fact limited the accessibility to meat for the Pre-Columbian civilizations.Explanation:

Why is it important that mitosis occurs like this
Answer: The cell divides upon these processes during a process known as mitosis. In mitosis, two daughter cells are formed. It is important that each of the daughter cells contain genetic information that is identical to that of the mother cell, as well as that there be no mutations. Mitosis is Important for three main things:
> Growth
> Repair
> Reproduction

Explain how pollution from one location
can affect the environment far away from the
source of the pollution
Answer:
Air quality is affected by natural processes. Wind can move pollutants from their source to far-away locations. It can still spread and harm living creatures and destroy their environments.
Explanation:
Air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.
What is Pollution?Pollution is defined as the introduction of harmful materials into the environment where the harmful materials are called pollutants. Pollutants can be natural, such as volcanic ash which can also be created by human activity, such as waste or runoff produced by factories. Pollutants harm the quality of air, water and land.
Many things produce pollution such as cars spewing pollutants from their exhaust pipes. Burning coal to generate electricity pollutes the air. Industries and homes generate waste and sewage that can pollute land and water. Pesticides which is chemical poisons used to kill weeds and insects which is seep into waterways and harm wildlife.
Thus, air quality is affected by natural processes where wind can carry pollutants to places far away from their source which can still spread and harm living beings and destroy their environments.

if mammalian cells receive a go-ahead signal at the g1 checkpoint, they will:
If mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.
What is the Cell Cycle?The cell cycle may be defined as the entire sequence of events happening from the end of one nuclear division to the beginning of the next nuclear division.
There are three major checkpoints in the cell cycle. One at the end of the G1 phase, the second at the end of the G2 phase, and while third is during the M phase.
Therefore, if mammalian cells receive a go-ahead signal at the G1 checkpoint, they will complete the cell cycle and divide normally.

What are villi?
don't spam
Answer:
Villi are finger-like outgrowths on the inner walls of the small intestine. The villi increase the surface area for absorption of the digested food.
Answer:
Villi are tiny finger-like projections seen in the small intestine. They are more than millions of villi in the small intestine performing the following functions: The villi absorb nutrients from the food and cause their conversion into glucose.
Where does energy go in respiration
Answer:
Summary. Through the process of cellular respiration, the energy in food is converted into energy that can be used by the body's cells. During cellular respiration, glucose and oxygen are converted into carbon dioxide and water, and the energy is transferred to ATP.
Which of the following statements correctly describes genes?
Answer:
Genes are made of DNA and are carried on chromosomes
Explanation:
For which one of the following functions is parenchyma tissue particularly suited?
A. Reinforcement and support C. Elasticity
B. Exchange of gases D. Formation or root hairs
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).
