Which of the following traits can be used to differentiate humans from our closest living primate relatives? Select all that apply (three). grasping hands large brain size extensive tool use bipedality, which is the ability to walk exclusively on two legsAnswer: bipedality (the ability to walk exclusively on two legs), large brain size, extensive tool use.
Answers
These three traits—bipedality, large brain size, and extensive tool use—are all unique to humans and separate us from our primate relatives.
One of the most distinctive traits that differentiates humans from other primates is bipedality, the ability to walk exclusively on two legs. This allows humans to move more quickly and efficiently than their four-legged primate relatives. Additionally, bipedality frees up the use of our hands to manipulate objects in our environment, which has allowed us to develop complex tool use.
Another major difference between humans and other primates is brain size. The human brain is much larger than that of our primate relatives, and its increased complexity allows humans to think abstractly and develop language and culture.Finally, humans have developed a much more advanced tool use than other primates. We have learned to use tools for a variety of functions, such as hunting and gathering food, building shelters, and creating art.

3. How does the ozone layer help shield the Earth? O by allowing all of the UV light to pass through by causing some of the UV light to bounce back into space by rerouting some of the UV light, causing it to go around our planet O by absorbing some of the UV light that harms living things
Answers
Answer:
When an ozone molecule absorbs UV-B, it comes apart into an oxygen molecule (O2) and a separate oxygen atom (O). Later, the two components can reform the ozone molecule (O3). By absorbing UV-B in the stratosphere, the ozone layer prevents harmful levels of this radiation from reaching Earth's surface.
Explanation:
Answer:
The last answer. By absorbing some of the UV light that harms living things.
Explanation:
As the harmful UV light heads for earth, the Ozone Layer absorbs a great amount of the harmful UV radiation that comes from the sun, and If it weren't for the Ozone Layer, we would probably all be practically blind from the radiation hitting our eyes.

Why there were no clear zones for using LB media with 1% olive oil for screening lipilytic bacteria
Answers
The reason for the clear zone may be that there is Insufficient lipolytic activity.
Why the clear zone?The absence of clear zones when using LB media with 1% olive oil for screening lipolytic bacteria could be due to Insufficient lipolytic activity.
Enzymes called lipases, which are produced by lipolytic bacteria, break down fats and oils. It's possible that the bacteria utilized in the experiment won't create lipases or have poor lipolytic activity, which would prevent them from efficiently hydrolyzing the olive oil in the media. There wouldn't be any observable clearing or lipid hydrolysis zones as a result.

State the unique characteristics of epithelial tissue.
Answers
Answer:
Characteristics of epithelium tissue
1.Polarity- Epithelium is arranged so there is one free surface (apical surface) and one attached surface (basal surface)
2.Cellular nature– Cells in epithelium fit closely together side by side and sometimes atop each other to form sheets of cells. These sheets are held together by specialized junctions.
3.Supported by connective tissue– Attachment to a layer of connective tissue at the basal surface forms a layer called the basement membrane, an adhesive layer formed by secretions from the epithelial cells and the connective tissue cells.
4.Avascular– Epithelium typically lacks its own blood supply.
5.Regeneration– Epithelium cells can regenerate if proper nourished.
6.Absence of nerves (except for a few axons in the deeper layers)
Classification scheme of epithelial tissue:
Typically epithelial tissue is classified on the basis of arrangement and shape of cells. For naming the tissue types, the arrangement of the cells is stated first, then the shape, and is followed by “epithelium” to complete the naming. For example; Simple Squamous Epithelium.

C. Angles measuring 100°, 10°, and 70°
D. Angles measuring 110°, 40°, and 40°
SUBMIT
Answers
The measurements that could create more than one triangle are options C and option D.
Explanation: For a triangle to exist, the sum of any two sides of a triangle must be greater than the length of the third side.
In option C, the angles measuring 100°, 10°, and 70° do not satisfy this condition, as the sum of the angles 10° and 70° is less than 100°, making it impossible to form a triangle. However, by rearranging the angles, such as 10°, 70°, and 100°, we can create a valid triangle.
In option D, the angles measuring 110°, 40°, and 40° also violate the condition for a triangle, as the sum of the angles 40° and 40° is less than 110°. However, by rearranging the angles, such as 40°, 40°, and 110°, we can create a valid triangle.

What is an atom?An atom is described as a particle that consists of a nucleus of protons and neutrons surrounded by a cloud of electrons.
Protons and neutrons make up the core nucleus of an atom, which is encircled by an electron cloud. In relation to the size of the atom as a whole, the nucleus is exceedingly small.
As a result, the electrons surrounding the nucleus are the primary target of interactions when particles or even light pass through an atom. The majority of the atom's remaining space, which includes the nucleus, is vacant.

Answer:
he raptors in the novel, following through to the film raptors, were larger than the species going by the name because during the writing of the novel, a previously discovered dinosaur named Deinonychus (closely related to Velociraptor, but larger) was rechristened as a Velociraptor species by some scientists, notably Gregory S. Paul.[1] Crichton wrote his novel based on the idea of a human sized raptor, but after the publication—when the movie was already in production—the idea of Deinonychus being a Velociraptor species was dropped.
During the movie's production, the effects supervisors acknowledged that the Velociraptor featured in the movie were sized identically to the larger Deinonychus. However, during the filming paleontologists came across a larger dromaeosaurid species named Utahraptor and the larger raptors remained, even though Utahraptor was substantially larger (21 feet long) than most of the movie's raptors. It should be noted, also, that at the start of the film a Velociraptor skeleton is uncovered in Montana - no examples of the dinosaur have yet been uncovered in the USA (although both Deinonychus and Utahraptor are American dinosaurs). The fossil skeleton is similarly inaccurately large. It is possible that the Velociraptor in the movie are re-classified Deinonychus, though in the book they are said to be Velociraptor mongoliensis.
The high intelligence of the film's Velociraptor is considered somewhat unlikely by scientists, given the relative size of their brains and comparisons with modern animals.[

The conclusion of the experiment is given as follows: When the uncooked egg was paused for a minute, the liquid within continued to spin due to inertia. When the egg was freed, the flowing liquid forced it to spin again.
Inertia describes an object's tendency to continue moving in the same direction unless a force changes its speed or direction. The word is correctly regarded as shorthand for Newton's first rule of motion, which describes the "principle of inertia."

Which of the following is not characteristic of annelids?
A. true coelom
B. segments
C. closed circulatory system
D. asexual reproduction
Answers
The characteristic that is not typical of annelids is D. asexual reproduction. Annelids are a phylum of segmented worms, and they possess certain distinct features:
A. True coelom: Annelids have a true coelom, which is a fluid-filled body cavity surrounded by mesodermal tissue. The coelom provides space for organs and allows for better movement and flexibility.
B. Segments: Annelids exhibit segmentation, with their bodies divided into repeated segments. This segmentation is evident externally and internally and allows for specialization and flexibility in movement.
C. Closed circulatory system: Annelids have a closed circulatory system, meaning that blood is contained within vessels and pumped by a muscular heart. This system facilitates efficient transport of oxygen, nutrients, and waste products throughout the body.
D. Asexual reproduction: Annelids primarily reproduce sexually through the exchange of gametes between individuals. While some annelids may have the ability to regenerate or reproduce asexually under certain circumstances, asexual reproduction is not a typical characteristic of the phylum. In summary, while annelids possess a true coelom, segmented bodies, and a closed circulatory system, asexual reproduction is not a common feature among them.
