We protect our homes and gardens from pests (insects), you protect your small business with an alarm system, you protect your health by having insurance and eating well and taking appropriate medication --so why would you not protect your ranch in any way possible from predators? Why are some ranchers resistant?
Answer:
because some crops need other animals to grow like with bees and humming bird they are considered predators but they help plants by spreding seeds.

What causes leaves to change color in the Fall?
Answer:
Chlorophyll Breaks Down
But in the fall, because of changes in the length of daylight and changes in temperature, the leaves stop their food-making process. The chlorophyll breaks down, the green color disappears, and the yellow to orange colors become visible and give the leaves part of their fall splendor.

Alternative energy sources like solar and wind power
are always available
b. are only replenished with human intervention
are renewable
d. are more versatile than fossil fuels
C.
Answer:
are only replenished with human intervention are renewable
Renewable alternative energy sources like solar and wind power only need human interaction to refill themselves. As a result, choice B is the right one.
Alternative energy sources are ways of producing energy that are more environmentally responsible, renewable, and sustainable than conventional fossil fuels like coal, oil, and natural gas. The significance of creating and utilising alternative energy sources has increased as concerns over the depletion of non-renewable resources and the effects of climate change become more and more apparent. Numerous alternative energy sources are being investigated and used globally due to technological breakthroughs and rising global awareness.

when a newly formed cell enters into interphase and begins conducting metabolic functions it's is. •G0 phase •G1phase •G2 phase •S phase
Answer:
Gap 1 (G1)
- This is the phase in which the cell undergoes normal growth and cell function synthesizing high amounts of proteins.
- The cell increases in size and volume as more cell organelles are produced.
- The cell can only move to the next phase, S after synthesizing enough ribosomes.
- As the phase is almost done, the mitochondria of the cell fuse into a network of mitochondria for effective energy production for cell processes.
- If the cell can not divide again, it enters the G0.

Answer:Sexual reproduction allows them to produce fit offspring that can survive under stressed environmental condition
Explanation:Reproducing sexually and asexually allows fungi to adjust as per the environmental condition.
When the conditions are favorable, they reproduce asexually and increase their number but when the condition are not favorable and environmental selective pressure occur then they undergo genetic variation through sexual reproduction to produce a stable and fit offspring that could survive under stressed condition with limited resources.
Asexual reproduction Since there are plenty of resources, the plant will want to reproduce quickly and colonize the area

40 POINTS ! compare and contrast the six nutrients of life (water, protein, carbohydrates, fats, vitamins, and minerals). with the names of the six nutrients along the top and the following headings along the side: role in nutrition, degree of difficulty of digestion, cost (high or low and why), chemical makeup (for example, carbon, oxygen, and hydrogen), main dietary sources, and how much is needed daily by a dairy cow, sheep, goat, and pig.
The World Health Organization (WHO) note that essential nutrients are crucial in supporting a person’s reproduction, good health, and growth. The WHO divide these essential nutrients into two categories: micronutrients and macronutrients.
Micronutrients are nutrients that a person needs in small doses. Micronutrients consist of vitamins and minerals. Although the body only needs small amounts of them, a deficiency can cause ill health.
Macronutrients are nutrients that a person needs in larger amounts. Macronutrients include water, protein, carbohydrates, and fats.
Keep reading for more information about where to find these nutrients, and why a person needs them.

what are the steps of photosynthesis
Explanation:
Step 1-Light Dependent
CO2 and H2O enter the leaf
Step 2- Light Dependent
Light hits the pigment in the membrane of a thylakoid, splitting the H2O into O2
Step 3- Light Dependent
The electrons move down to enzymes
Step 4-Light Dependent
Sunlight hits the second pigment molecule allowing the enzymes to convert ADP to ATP and NADP+ gets converted to NADPH
Step 5-Light independent
The ATP and NADPH is used by the calvin cycle as a power source for converting carbon dioxide from the atmosphere into simple sugar glucose.
Step 6-Light independent
The calvin cycle converts 3CO2 molecules from the atmosphere to glucose

Malaria, a type of parasite, infects 500 million people each year by infecting the red blood cells of its host. The virus, HIV, that causes AIDS, reports 50,000 newly infected persons. Which statement best differentiates the pathogens, parasites and viruses?
options: Although both rely on other living organisms to survive, viruses are usually beneficial.
Although both rely on other living organisms to survive, parasites feed on the host organism.
Although both are living organisms, viruses break down dead plants and animals that other organisms use.
Although both are living organisms, parasites depend on the cells of living things to reproduce.
Answer:
The second statement clearly differentiates the pathogens best. Parasites feed on living host while viruses depend on the cells of other organisms to survive and reproduce as they cannot function outside a living host.
Although both rely on other living organisms to survive, parasites feed on the host organism. The correct option is B.
What are parasites?A parasite is an organism that lives on or in the host and obtains its food from or at the expense of the host.
Protozoa, helminths, and ectoparasites are the three main types of parasites that can cause disease in humans.
They frequently go unnoticed because they have few symptoms. However, these infections frequently result in serious illnesses such as seizures, blindness, heart failure, and even death.
A parasitic relationship takes place when one lifeform, the parasite, feeds on another organism, the host, causing harm and possibly death.
The parasite lives on or in the host's body. Tapeworms, fleas, as well as barnacles are examples of parasites.
Thus, the correct option is B.
