mendel’s law of segregation states that the two alleles for each gene separate during gamete formation. during which stage of meiosis do the alleles separate?
The stage of meiosis at which the alleles separate is anaphase. The correct option is B.
What is meiosis?Meiosis is a type of cell division of germ cells that produces gametes such as sperm or egg cells in reproducing organisms through gametes.
It entails two rounds of division, resulting in four cells with only one copy of each chromosome.
Meiosis 1 separates a pair of homologous chromosomes and converts a diploid cell to a haploid cell. It is divided into four stages: prophase, metaphase, anaphase, and telophase.
The homologues are pulled apart and moved to opposite ends of the cell during anaphase I.
The sister chromatids of each chromosome, on the other hand, remain attached to one another and do not separate. Finally, in telophase I, the chromosomes arrive at the cell's opposite poles.
Thus, the correct option is B.

Explanation:
hope this helps. ♥️
Parasitism is the type of symbiosis that occurs between a deer and the tick. So, the correct option is C. This is because bacteria infect their host cell which is found in Deer.
What do you mean by Symbiosis?Symbiosis may be defined as a relative ecological association between the individuals of two or more different species.
The type of symbiotic relationship found between oxpecker and zebra is Mutualism. This is because oxpecker is able to get its prey (food), while zebra is benefitted from the removal of insects from their body. So, the correct option is A.
The type of symbiotic relationship between Humans and bacteria living in their digestive tract is Mutualism. This is because Humans are benefitted from bacteria as they assist in digesting food, while bacteria also benefit to find a proper place where unlimited food is available. So, the correct option is A.
The type of symbiotic relationship between Barnacles and whales is Commensalism. This is because Barnacles are benefitted from excess food and easy transportation, while whales are neither benefitted nor harmed by this relationship. So, the correct option is B.
Therefore, each of the questions are properly described above.

A sieve is a container with a mesh or perforated bottom. What is the most common use for a sieve? A. to steam cook chemicals in the lab B. to store liquid substances C. to allow gases to escape from reactions D. to filter larger particles out of a mixture
Answer: D
Explanation: Sieves are used to separate the solid smaller particles from a mixture. They are usually made of metal or fine plastic mesh, with openings between the wires that are sized according to the sizes of the desired particles in the mixture. Dried foods such as beans and rice are separated by using screens with openings of different sizes, small for whole grains, larger for cracked grains. Other kinds of products which require separation may be filtered through sieves, including sugar mixtures before they are packed or bottled.
A population of beetles is mostly composed of individuals with the dominant green color, but there are several with the recessive brown
color. A displaced species of bird moves into the habitat and preferentially preys upon the green beetles. Over time, what can be expected
to happen to the beetle population?
O A. The beetles will migrate to avoid being eaten by the birds in the habitat.
OB. The beetle population will become extinct.
O C. The beetle population will stabilize because the birds will not eat more beetles than necessary to maintain ecological balance.
O D. The brown beetles will become more common.
The green beetles will decrease in number while the brown beetles will become more common.
According to Darwin's theory of evolution, organisms that are better adapted to their environment are able to live longer and survive long enough to reproduce thereby perpetuating their favorable characteristics in the population.
Since the green beetles are more common but they are preferentially preyed upon by the invasive bird species, the green beetles will decrease in number while the brown beetles will become more common.

If you throw a ball straight up into the air, when is the kinetic energy the greatest?
Question 4 options:
Right before you catch it after it falls back down.
When the ball reaches the highest point and stops briefly.
Half the distance on the path traveling back down.
Half the distance on the path traveling up in the air.
Half distence on the path traveling up in the air.
Explanation:
When the ball is on thr ground there and not moving there is no potential energy or kinetic energy, when the ball is tossed into the air it will reach maximum height which is determined by how much kinetic energy it has (air resistence is important however) when the ball reaches its velocitu is 0 and all of the energy in the system is potential energy, as the ball falls to the ground that potential energy is converted to kinetic energy
If a ball is thrown straight up into the air, the kinetic energy is greatest when the distance is half on the path travelling up in the air. Thus, the correct option is D.
What is Kinetic energy?Kinetic energy is the energy associated with the body which is under motion. Kinetic energy is directly proportional to the distance, mass and velocity of the object.
When the ball is thrown on the ground and is not moving then there will be no potential energy or kinetic energy as the height and velocity is zero when the object is on ground. When the ball is tossed into the air, it will reach maximum height which is determined by the kinetic energy it has and the air resistance when the ball reaches zero velocity and the greatest kinetic energy is observed when the body attains half of the total distance on the path.
Therefore, the correct option is D.

7. Explain the following: All compounds are substances,
but not all substances are compounds."
Answer:
Below
Explanation:
"All compounds are substances, but not all substances are compounds."
In simpler terms, let us use an example. Look at the image below.
In a big circle, there are substances. And in the small there are compounds. Since the compounds are inside the big circle, they are compounds, but as you can see, the substances are not inside the compounds so they cannot be considered compounds.
If you think about it, a substance is anything. So would you think a bottle, for instance, is a compound? A compound is a mixture of molecules. And a substance is most likely a combination of atoms, which are elements.

How do lenses correct vision?
A.) They bend the cornea.
B.) They reflect light away from the retina.
C.) They reflect light towards the retina.
D.) They bend light so that it focuses on the retina.
Answer: D
Explanation:
Glasses correct vision by allowing your eyes to focus light on the correct spot of your retina. The curved frames bend light, and with the right prescription, these frames manipulate the light to reach the correct spot on your retina.
Glasses improve vision by focusing light on the retina. With the right prescription, curved frames bend light to reach the retina.Therefore, option (D) is correct.
What is the function of lenses?Your eyes will be able to focus light on the appropriate portion of your retina when you wear glasses. This will result in improved vision. Light is bent by the curved frames, and when combined with the appropriate prescription, these frames may modify light such that it falls on the retina in the correct location.
Myopia, often known as the inability to see things that are far away, can be rectified with a lens that has a diverging power, which lowers its overall strength. The condition known as hyperopia, in which a person has difficulty seeing things that are up close, can be treated with a lens that converges light in order to boost its power.
