Answer:

Think foxes eat rabbits. The more rabbits than the more foxes have to eat which will cause a decrease in rabbit population and likely an increase in fox population.

Explanation:

Rabbits and foxes have a predator-prey relationship. If a community has an abundant number of rabbits, then the population of foxes in that area will also increase as there will be abundant food for them. As the population of foxes increases, the population of rabbits will start to decrease as there will be more predators to feed on them. Hence, if the population of foxes keeps on increasing, rabbits may migrate or become completely eradicated from that particular area.

While we usually think of fever as a bad thing, a fever is actually signifying that an immune response is progressing! Overall,
zalisa [80]

Answer:

E. Interleukin-1

Explanation:

Interleukin-1 is produced by macrophages and is involved in promoting the proliferation of helper T cells. Interleukin-1 also acts on the hypothalamus to cause fever. Fever refers to abnormally high body temperature. During infection and inflammation, the hypothalamic thermostat is reset in response to interleukin-1 resulting in fever. The presence of certain bacterial toxins in the body triggers the release of interleukin-1 from macrophages and the body temperature is elevated. Fever inhibits the growth of some microbes, intensifies the effects of interferons, and stimulates the body's immune reactions.

To be considered part of the same population organisms must have a reasonable chance of mating with each other. Are two wild ros
IRISSAK [1]

Two questions have been asked, and responded to

Answer:

For question 1: The statement is true

For question 2: Yes, the two wild roses are of the same population

Explanation:

Population is simply the total number of organisms of the same species LIVING and BREEDING together in a given area.

I) To be considered part of the same population, two of more organisms MUST BE able to mate i.e produce gametes that are viable enough to fuse together and create new offsprings.

2) Yes! Two wild roses separated by a wide road belong to the SAME POPULATION because

- it is still a given area or habitat

- transfer of pollen grains by agents such as wind or insects is possible, thus breeding still occurs.

Explain why crops in the arctic grow larger than normal during the summer months
Romashka-Z-Leto [24]

Answer:

More sunlight, more photosynthesis

Explanation:

This is because when the sunlight hits the leaves, it allows photosynthesis to occur. But when you have extended periods of sunlight, like summer, it causes photosynthesis to continue for a longer time, which causes rapid energy storage. This makes excess food for the plant which gives the plant more energy for growth and pollination.

Hope this clears it up for ya:)

klasskru [66]

Answer: c. proteasome

Explanation:

Proteasomes are extremely important multi-catalytic proteases and are involved in various cellular functions. The proteasome is an essential component of eukaryotic cells and is responsible for the ATP-dependent proteolytic degradation of most cellular proteins. They are present in the nucleus and cytosol and can represent up to 1% of total cell proteins. Proteasomes generally degrade proteins to small peptides, most of which are rapidly hydrolyzed by cytoplasmic exopeptidases. It catalyzes the rapid degradation of many enzymes, regulatory proteins, and eliminates abnormal proteins resulting from mutation or damaged proteins. The inability of this cellular organelle can lead to neurodegenerative diseases, such as Parkinson´s disease.
