The arm or forelimb of humans, horses, goats, and mice all exhibit the same three bone structures: humerus, ulna, and radius. Wh

ich statement BEST explains this common skeletal structure?
The limb bones are similar across these species because they share a common ancestor.

The limb bones are the same across these species because all of them move in a similar way

The limbs are similar because of the recurring patterns of genetic mutation that are common in the animal kingdom

The limbs are structurally similar due to convergent evolution - different organisms evolving to become structurally similar

Answer:

<em>"The limb bones are similar across these species because they share a common ancestor </em>is a right option.

Explanation:

Forelimb (humerus, ulna, and radius) is a homologous structure in all vertebrates. This means that these structures are evolved from the same lineage. Homologous organs could perform different functions but they are structurally similar.

If there is any similarity in different animal's forelimb structure (e.g. horses, goats, and mice), then they are considered to be of same evolutionary origin. Their structures are similar but not function.  Evolutionary biology tells us that homologous structures are adapted to different environments as a result of modifications from a common ancestor.

In a nutshell, forelimbs of ancestral vertebrates have evolved into the running forelegs of mice, goats and horses, and the grasping hands of humans.

<h3>What are the benefits of technology?</h3>

Sales will probably improve as a result of technology that makes it simpler for people to buy from you, including an e-commerce solution and numerous payment apps. Marketing departments are forced to adapt the social media platforms that your clients and potential customers use since they are born and die on a monthly basis.

The tasks that HR departments perform for hiring, reviewing applicants, onboarding, and training involve a significant amount of technology. The more HR duties you can complete using technology, the quicker they can be completed and the less likely it is that you will make a mistake that could result in a lost recruit, an employee leaving, or a lawsuit. Employee education on topics like benefit enrollment and corporate policies, for instance, guarantees appropriate paperwork is done and cuts down on training time for new hires.

An individual running a marathon may experience periods of oxygen deprivation that can lead to
Harman [31]

Answer:

A. anaerobic respiration in muscle cells, forming lactic acid

Explanation:

Running marathon is a vigorous exercise, which often leads to excessive use of oxygen in the cells of the athlete. This causes the cells to switch from the aerobic (with oxygen) to the anaerobic (without oxygen) mode of respiration. This anaerobic respiration produces a product called LACTATE OR LACTIC ACID.

The lactic acid becomes excessive and gets stored in the muscle cells of the athlete. This often leads to cramps, muscle pulls etc. during the marathon. Therefore, an individual running a marathon may experience periods of oxygen deprivation that can lead to anaerobic respiration in muscle cells, forming lactic acid.

Why are a plant's Stomata generally open during the day and closed at night?
marin [14]
When stomata are open, carbon dioxide enters the plant through stomata. Carbon dioxide is necessary for the process of photosynthesis in which it is converted together with water into oxygen and glucose. For most plants, it is necessary that stomata are opened during the day when there is a lot of Sunlight also necessary for the process of photosynthesis.

However, some plants from the arid locations have <span>stomata closed during the day, so they reduce water loss that way. In the night when is colder, stomata open and carbon dioxide enters through stomata. </span>
