Bone mineral density (BMD) is a measure of bone strength. Studies show that BMD declines after age 45. The impact of exercise may increase BMD.

a. True
b. False

Answers

Answer 1

Answer:

As you age, your body may reabsorb calcium and phosphate from your bones instead of keeping these minerals in your bones. This makes your bones weaker. When this process reaches a certain stage, it is called osteoporosis. Many times, a person will fracture a bone before they even know they have bone loss.

B. provides the most precise measurement of a natural object.
C. can be searched quickly for the most relevant observations.
D. can evaluate the validity of a logical argument in a discussion.

Answers

Answer:

C. can be searched quickly for the most relevant observations.

Can be searched quickly for the most relevant observations. Therefore, option (C) is correct.

What is a database?

A database is a collection of organized data that can be searched, updated, and analyzed to obtain specific information or insights. One of the main advantages of a database is that it allows for quick and efficient searching and retrieval of relevant information.

This is particularly useful for sharing information among multiple users, as it allows for easy access to the same data from different locations and at different times. While a database can be used to store a wide range of information, it is typically not used to evaluate the validity of a logical argument, measure natural objects, or identify sources of error in an experiment.

The function of the liver in humans is to maintain the [glucose] circulating in the blood stream at reasonably constant levels. This is so organs like the brain that use primarily glucose as their carbon source to produce energy via ATP have a steady supply of glucose. It also ensures that the levels of glucose in the blood stream do not get too high. Using the plots from problem 6, discuss why it makes sense that glucokinase in liver would behave differently than the hexokinase in other cells.

Answers

Answer:

Due to difference in function.

Explanation:

Glucokinase in liver behave differently than the hexokinase in other cells because glucokinase performs different function in the body. Glucokinase is an enzyme that is responsible for sensing the glucose level in the blood and also plays a key role in the storing of glucose as glycogen while on the other hand, this storing ability is absent in hexokinase so that's why the glucokinase in liver behave differently than the hexokinase in other cells.

Which of the following biotic factors is associated with increasing the capacity of the organisms to move across fragmented landscapes? Patch size, connectivity,Patch shape, Distance from other landscape patches

Answers

Answer:

connectivity

Explanation:

Natural and anthropogenic alterations affect the landscape. The unmeasurable use of the land for farming, cattle industry, buildings, among many other activities, has caused a severe fragmentation in the original landscape that has been seriously affecting biodiversity.    

Fragmentation occurs when a big extension is transformed into many different and smaller patches, separated by another type of cover. You can imagine, for instance, an area used for mono-culturing, which you can see as a homogeneous space of the same texture and color, and small green islands of original vegetation dispersed in this cropped area. These small islands are separated from each other by the crop.

These alterations produce patches or tesserae in the landscape. Patches are relatively homogenous areas with well-defined borders and environmental characteristics very different from those of the surrounding areas. These are like islands. You can think about patches or tesserae as the remaining pieces or units of the original landscape dispersed inside an affected bigger-sized area.

Fragmentation generates a significant loss of physical continuity between the different areas of the original habitat. It might negatively affect biodiversity by decreasing patch sizes, completely isolating them from each other, and increasing the border effect.

Many species can not survive if they are not in the original habitat. Probably they do not find enough food or shelter, or they are very exposed to predation. So they need to stay in the patch. Most of these species are not even adapted to living on the border of the patches. Eventually, fragmented areas can not support some population species that end by dying because they can not survive for a long time in that reduced place. Patches are not suitable to support too many species.

For these reasons, the connection between islands becomes so important.  To allow species to move from one place to the other, interact with other species, reproduce, find food, shelter, avoid predation. In other words, survive.  Connectivity is how the territory makes possible individuals flow or genetic flow, between the different tesserae.
