The coffee, or rather the coffee beans, are crop that can be considered as a luxury crop. The reason why it can be considered as luxury crop is that it is not a crop that is needed for food, or satisfying the basic needs of the humans.

Explanation:

Answer:

Predator population will also decrease

Explanation:

This is because the predators are dependent on their prey without the prey they would starve and die out so with less possible food the less of a population for what ever eats that prey which can lead to a chain reaction throughout the ecosystem however it is also the other way around too the more possible food the more chance for babies to be born and not starve to death.  

Answer:

1. Shrink

2. Swell

3. Neither

Explanation:

The percentage of water indicates how pure the water is, i.e. how concentrated the molecules of water are.

The higher the percentage of water, the more water molecules there are in the space.

Water molecules move from a high concentration to a low concentration across a semi permeable membrane, by the process of osmosis.

In beaker 1, the water outside is 89%, and inside the bag is 92%. That means the water inside the bag is at a higher concentration than outside. That means water will leave the bag, moving from a high concentration to a lower concentration outside. The bag will shrink.

In beaker 2, the water outside is 97%, and inside is 92£%. That means the water inside the bag is a lower concentration than outside. That means water will enter the bag, moving from a higher concentration outside to a lower concentration outside. The bag will swell.

In beaker 3, the concentration of water inside and outside is the same. That means they are in an equilibrium (the movement is balanced) so neither will occur

Answer:

C. Genes are transcribed into mRNA, the mRNA is then translated into proteins, which determines specific traits.

Explanation:

Genes are segments of the genetic material (DNA) that encodes certain products, which are heritable. In the central dogma of biology, genes are expressed via two processes viz: transcription and translation.

Transcription is the process whereby the information in genes are used to synthesize mRNA molecule, while Translation is the process whereby the mRNA molecule is used to synthesize proteins in the ribosome.

The proteins are responsible for the individual characteristics or traits possessed by living organisms. For example, MELANIN GENE is transcribed into MELANIN mRNA, which is then translated into MELANIN PROTEIN responsible for the skin colour (trait).

Answer:

Mutations

Explanation:

Bacteria can mutate, for example bacteria have high mutation rates since they reproduce rapidly, therefore they can build up an immunity.

Answer:  clock cant clap

Explanation:

Answer:

The correct option is "nucleus, chloroplast, and cell wall"

Explanation:

The specimen described in the question is said to be green aquatic plant. Hence, the organelles expected to be viewed are those present in a pant cell.

Although, nucleus (stores the genetic material) is present in both plant and animal cells, however, chloroplast (to provide the green colour for the aquatic plant) and cell wall (for the cell's rigidity and support) are only found in a plant cells.

Answer:

a

Explanation:

The cuticle in the plants minimizes the water loss or transpiration from leaves. The correct option is A.

Transpiration is the process by which water vapor is lost via the stomata of plants. When the weather is very hot, the plant's loss of water vapor cools it down, and moisture from the stem and roots moves upwards or is 'pulled' into the leaves.

The evaporation of extra water from stomata in plant leaves is known as transpiration. It is necessary for some upward movement of water in plants. It aids in the regulation of plant temperature.

To transpire, water vapor must diffuse through this motionless layer from the stomata to the atmosphere, where it will be removed by moving air. The cuticle present in the waxy leaves prevent excess transpiration.

Thus, the correct option is A.

Answer:

All living things are made up of cells.

The cell theory is a widely accepted principle of biology. Scientists that contributed to the cell theory include; Theodor Schwann, Matthias Schleiden, and Rudolph Virchow.

The cell theory states that;

All living organisms are made up of cells and they may be unicellular or multicellular.

The cell is the basic structural and functional unit of life.

Cells arise from pre-existing cells.  

Answer:

allways

Explanation:

i'm pretty sure that's right

Explanation:

The structure of multicellular fungi is formed by filaments called hyphae, and the set of hyphae is called mycelium. Hyphae are made up of the substance chitin.

They can be of two types: vegetative or reproductive. In vegetative multicellular fungi, hyphae are found inside the substrate to remove the food.

And in the case of reproductive multicellular fungi, there is the formation of spores, which will form the fruiting body for reproduction.

Answer:

(Wow! Weird how this pooped up, I just finished this biology lesson.)

Sex chromosomes are the gene that decides on our gender. The males have X and Y sex chromosomes (XY). Females have only two  X sex chromosomes (XX).

More info: Because males have both X and Y sex chromosomes, their genes decide the offspring's gender.

Answer:

The sex chromosomes are referred to as X and Y, and their combination determines a person's sex. Typically, human females have two X chromosomes while males possess an XY pairing. This XY sex-determination system is found in most mammals as well as some reptiles and plants
