Answer:
The correct answer is- Resistance
Explanation:
The ability of any organism in a population to tolerate a chemical like insecticide, pesticide or antibiotic which is designed to kill it or slow its reproduction is called resistance.
For example, the antibiotic resistance is seen in some bacteria like MRSA(Methicillin-resistant staphylococcus aureus). They gain this resistance because they have some variant traits in their genome which provide them resistance against these chemicals.
These individual are selected through natural selection when the environmental condition changes and become adverse. So the correct answer is resistance.
Answer:
Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.
Explanation:
Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.
In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.
Answer:
<u>a) strong joints with restricted movement.</u>
Explanation:
Joints which are closely fitted cannot allow free movement because movement requires space in the joint so the bones can move in this space. So a closely fitted joint allow restricted or no movement at all. Weak joints with restricted movements are called weak because they are not well fitted closely. Strong joints with restricted movement is closely fitted, one of the example is joints of skull.
The ecosystem of the forest is formed by the interaction between the abiotic and biotic factors. Abiotic factors are the non-living factors: water, temperature,light,cloud cover, and soil. Biotic factors oh the other hand are the living organisms. Tropical rain forests<span> are hot, moist forests found near Earth's equator.</span>
Temperate rain forests are cool and dry.
Abiotic factors in temperate rain forest:
1. Temperature:The climate in the temperate rain forests is mild.
2. Water: moist and lush.
3. Light: many clouds block the sunlight.
4. Soil: nutrition rich.
Biotic factors:<span>beavers, raccoons , cougars and black bears. </span>
Abiotic factors in tropical rain forest:
1. Temperature: hot, near the Earth's equator
2. Water:60
to 160 inches of precipitation
Biotic factors: the greatest
biodiversity in the world<span>,
rubber and bamboo trees, sloths, anteaters, poison dart frogs, </span>
