Will lactase, the enzyme that digested the ice cream's lactose, also work on the lactose found in cheese?
Answer:
Yes
Explanation:
This is because lactose found in any dairy product will always have the same molecular structure. The lactase enzyme breaks down lactose because of how it is structured, so it does not matter where the lactose comes from.

Water is an adhesive substance. This means that water particles
A. are attracted to other types of particles.
B. are repelled by other water particles.
C. are attracted to other water particles.
D. are repelled by other types of particles.
Answer:
A
Explanation:
are attracted to other types of particles.
Adhesion is the term for the attraction of substances between distinct phases. It uses the attraction of water to other polar compounds, as an illustration, hence option a is correct.
What is the characteristic of water?Cohesion is the tendency of particles to cling together, it uses the attraction of water molecules to one another.
Water has a characteristic called cohesion in which water molecules form bonds with one another. As a result, surface tension develops and raindrops start to form.
Water molecules can interact with other molecules through adhesion, this enables water to adhere to surfaces like windows and other things.
Therefore, water is a strong adhesive that adheres effectively to many different materials, hence option a is correct.

Give three differences between parenchyma and selerenchyma?
Answer:
Parenchyma cells have thin primary walls and usually remain alive after they become mature while Sclerenchyma cells have thick lignified secondary walls and often die when mature.
Parenchyma forms the "filler" tissue in the soft parts of plants while Sclerenchyma provides the main structural support to a plant.
Parenchyma cells are usually loosely packed with large intercellular space while Sclerenchyma cells has no intercellular spaces between the cells.

1. Meiosis is two divisions of a reproductive cell’s nucleus. It occurs in a continuous series of steps. Compare AND contrast the steps of meiosis I to meiosis II.
2. Describe mutation. Give EXAMPLES where mutations could be harmful, beneficial, or neutral.
Answer:
1. Both Meiosis I and II have the same number and arrangement of phases: prophase, metaphase, anaphase, and telophase. 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.
2. Answer! A Mutation occurs when a DNA gene is damaged or changed in such a way as to alter the genetic message carried by that gene. The majority of mutations are neutral in their effects on the organisms in which they occur. Beneficial mutations may become more common through natural selection. Harmful mutations may cause genetic disorders or cancer. I hope it helps! :)

Osmosis is important to cells because _______ *
cells contain fluids that are mostly water
cells are filled with fluids that are mostly sugar
cells need to be kept cool
cells need food
( PLEASE ANSWER THIS ASAP!!!) Thanks!!
Answer:What is the main function of osmosis? Osmosis helps in stabilizing the internal environment of the organism by balancing the levels of water and intracellular fluids. Also, the nutrients and minerals enter the cell by osmosis which is necessary for the survival of cells.
Explanation:
Osmosis maintains the osmotic pressure in cells. the answer to this question is options A and B.
Osmosis is essential for the cells due to two reasons:
1. Cells are made up mostly of water-based fluids. The process of osmosis involves the movement of water molecules from a region with a lower concentration of solutes to an area with a greater concentration of solutes through a semipermeable membrane. This aids in preserving the equilibrium of water within and outside the cell, ensuring that the cell remains hydrated and performs as intended.
2. Sugar-based fluids are the main component of cells' fluids. Osmosis also affects how much sugar and other solutes are present inside cells, helping to control their concentration. Osmosis will cause water to enter the cell if the concentration of sugar inside the cell is higher than the outside, diluted the sugar, and maintain equilibrium.
Therefore the correct answer is options a and b.

Overgrazing reduces grass cover and negatively impacts the soil health by reducing it's ability to hold water . How can Overgrazing be prevented and support a more sustainable use of grasslands ?
A. Allow developers to buy rachlands for housing .
B. practice moving confined cattle every few days
C. Allow unlimited animals to graze in a given area to reach carrying capacity.
D. practice grazing an area of land at the same stage of plant growth each year .
Answer: C. Allow unlimited animals to graze in a given area to reach carrying capacity.
Explanation: I choose this as the answer because the animals grazing in the wrong parts be part of the reason the soil can't hold the water it needs, so allowing animals in a particular area that's less of a problem with Overgrazing would be helpful

Nebulae are different luminous regions of the interstellar medium that can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.
What is dust?All the stuff between stars is referred to as interstellar matter by astronomers, and the complete collection of interstellar matter is referred to as the interstellar medium (ISM). Some interstellar material is gathered into massive clouds that are each referred to as a nebula.
Tiny pieces of solid matter drifting about in the region between stars make up cosmic dust. It's not like the dust you find in your home; instead, it has tiny particles that range in size from collections of just a few molecules to grains that are 0.1 mm in size.
Therefore, an interstellar medium can be made up of cosmic dust as well as ionized, neutral, or molecular hydrogen, hence option C is correct.

Which is the most efficient way to avoid DNA mutations from UV radiation?
Avoid getting X-rays at the doctor’s office.
Avoid protective shields during X-rays.
Avoid UV radiation by wearing sunscreen.
Avoid UV radiation by using a tanning bed.
Answer:
Sunscreen is the best, and most efficient way to avoid DNA mutations. UV radiation causes thymine dimers in the DNA complex, so limiting UV radiation is key to avoiding DNA mutations.
Explanation:
The most efficient way to avoid DNA mutations from UV radiation is to avoid UV radiation by wearing sunscreen. Thus, the correct option is C.
What is DNA mutation?DNA mutation may be defined as the process that induces sudden, stable, and inheritable changes in the genetic material of organisms through various factors.
The UV radiations are the most potent physical agent that induces DNA mutation. But in order to avoid such kinds of DNA mutations from UV radiation one must be required to be protected from such kinds of harmful radiation with the help of sunscreen.
The UV radiation induces DNA mutations by causing the dimerization of the thymine base, which significantly alters the whole sequence of genetic material.
Therefore, the most efficient way to avoid DNA mutations from UV radiation is to avoid UV radiation by wearing sunscreen. Thus, the correct option is C.
