A researcher states that bone density in women is negatively associated with age. This means: A. above average values of age tend to accompany below average values of bone density. B. above average values of age tend to accompany above average values of bone density.
C. below average values of age tend to accompany below average values of bone density.
D. older women aren't any more likely than younger women to have below average bone density.

Answers

Answer 1

Answer: This means that the older the woman, the lower the bone density. So older women are more likely to have below average bone density: the correct answer is

A. above average values of age tend to accompany below average values of bone density.

Answer 2

Answer: A. above average values of age tend to accompany below average values of bone density.

If we evaluate the relationship between bone density and age of women, it is described as having a negative relationship or correlation. In simpler terms, in the context of development if one variable increases then the other in response, decreases. Paradoxical. Thus, like in this situation, as women gets older the lesser probability and susceptibility they are to have bone density complications.

explain the changes in the skeletons during the transition in habitat according to the theory of natural selection

Answers

Changes in the skeletons during the transition in habitat according to the theory of natural selection include their modes of histogenesis during the time. There were also observed to have modifications in the exoskeletons which they thought arise exclusively from the neural crest.

According to natural selection, skeletal changes occur gradually as individuals adapt to their environment and pass these changes on to their descendants.

We can arrive at this answer because:

During the transition to a new habitat, some individuals in a group of living beings adapt to the habitat.

This adaptation allows individuals who have skeletal modifications to have adaptive advantages and manage to survive in the new habitat.
These modifications are passed on to descendants through genetics, which means that new individuals are born with the skeletal modification, while individuals without this modification die before producing descendants.

As a result, the skeletal modification takes place gradually in the population of individuals as new members are born and old members die.

Orange roughy fish are a fourth-level consumer. We may see fifth- or sixth-level consumers, but not as many as at lower levels on a trophic pyramid. Why are the upper levels of a tropic pyramid limited?

Answers

As energy is lost through the energy pyramid, where it is the primary producers at the base, the upper levels of a tropic pyramid are limited as there is less to consume from as you go down the pyramid.

Answer:

An ecological pyramid is a graphical representation of the distribution of the biomass to different organisms in successive trophic levels. The energy is being lost by 10% in every higher trophic level, when one organism is consumed by another organism in a food chain. Therefore, the number of trophic levels in a pyramid will be limited.

Why are plants and animals able to survive in the tundra?

Answers

The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.

What is tundra region?

Snow covers tundra lands for the majority of the year, but summer provides bursts of wildflowers.

The small plants of the tundra employ dormant strategies, producing seeds only occasionally, turning with the sun to absorb energy, and growing protective coverings.

The ability to build subterranean insulated tunnels as well as heavy winter coats, seasonal color-changing camouflage, and efficient body shapes have all been developed by animals that live in the Arctic tundra.

Therefore, The Arctic and the summits of mountains are home to tundra ecosystems, which are characterized by their lack of trees and harsh climates with little rainfall.

Answer: Plants and animals are able to survive in the tundra because they have adaptations that allow them to thrive in the harsh conditions of the Arctic and sub-Arctic regions. These adaptations include thick fur or feathers to insulate against the cold, small body size to minimize heat loss, and the ability to store food and nutrients during the short growing season. Additionally, many tundra plants have shallow roots that can absorb nutrients quickly when they are available, and some have developed the ability to photosynthesize at low temperatures and with minimal sunlight.
