The main function of the PNS is to connect the CNS to the limbs and organs, essentially serving as a relay between the brain and spinal cord and the rest of the body.

The K-selection reproductive strategy maximizes the survival of offspring
by producing
Ofew offspring with high levels of parental care
Ofew offspring with low levels of parental care
O many offspring with high levels of parental care
Omany offspring with low levels of parental care
Answer:
The K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Explanation:
Depending on how many offsprings members of a species produce and how much care they invest in them, we can divide species into two categories:
r-organisms. These organisms produce many offspring, sometimes even thousands of them. They live in unpredictable, dangerous environments with a lot of predators. This is why most of their young die. It's important for at least some of them to survive so that they can continue reproducing and keep the species alive. The parents don't invest much care into their young. Some examples of these species are mice, rabbits, weeds, and bacteria.K-organisms. These organisms are the opposite of r-organisms. They live in more stable environments, which guarantees that their lifespan will be longer. This is why it's not necessary for them to produce many offspring. Parents invest a lot more care into their young. Some examples of these species are humans, elephants, horses, and primates.Based on this information, we can conclude that the K-selection reproductive strategy maximizes the survival of offspring by producing few offspring with high levels of parental care.
Answer:
Answer choice A
Explanation:
Few offspring with high levels of parental care is a characteristics of K-selected species.
care of chicks at the age of between 8 to 20 weeks is called ????????​
Answer: Brooding
Explanation:
Chicks are kept at high temperature after hatching this process is called brooding.
The chicks require 95-100 degrees temperature for brooding they are not allowed to mix with the flocks until 20 weeks after their birth.
Until this time the chicks learn to eat and drink water.
Overheated chicks can dehydrate and they grow slowly.
What part of DNA determines traits?
Answer:
The traits of a living thing depend on the complex mixture of interacting components inside it. Proteins do much of the chemical work inside cells, so they largely determine what those traits are. But those proteins owe their existence to the DNA (deoxyribonucleic acid), so that is where we must look for the answer.

This DNA strand consists of eight pairs of nitrogenous bases. How many different sequences of eight bases can you make? Explain how you found your answer.
Answer:
Explanation:
it would be 4 (possible bases) to the power of 8 because you need to multiply 4, eight times for the number of sequences. Therefore, the answer is 65, 536 possible sequences.
Biodiversity is partially influenced by net primary productivity. The highest rates of NPP can be found in
