Rock A = It is a metamorphic rock that experienced tremendous heat and pressure due to massive, moving tectonic plates.
Metamorphic rocks are rocks that have been somewhat squished and transformed by heat and pressure. These rocks often have different layers as the rocks go through pressure and are literally look like rocks that have been piled up and then stuck together. The best indicator of this rock being a metamorphic rock is the wavy elongated stripes. The stripes are created from the different rock elements being pressed together over time.
Rock B = It is a sedimentary rock made primarily from lithification of organic material.
Sedimentary rocks are rocks that have been formed by different substances that come together due to the different weather conditions. The best indicator of this being a sedimentary rock is how the rock came together and looks like a bunch of shells were glued together.
Rock C = It is an igneous rock that was formed above Earth’s surface.
Most igneous rocks have smooth outer layers. These rocks are often made with solidified magma from volcanoes. The best indicator of this being an igneous rock is the indication of it being a solidified piece of magma.
Answer;
-Birth defects
Explanation;
In animals, long-term exposure to DDT can cause death or severe birth defects.
-DDT stands for dichloro-diphenyl-trichloro-ethane. It is an insecticide/pesticide previously used on crops. DDT has an adverse impact on many organisms such as crayfish, fish, shrimp, and other animals such as mammals.
DDT is slightly to moderately acutely toxic to mammals, including people, if eaten.Animals given potentially fatal doses of DDT develop liver lesions and those given DDT over a long period of time develop liver changes. In these animal populations DDT may cause birth and reproductive defects.
The food handler should wash his/her hands before preparing other ingredients for the sandwich. The food handler must be touching some tools when grilling chicken, so his/her hand need to be sanitized. Using a new glove after washing hand will be better since it gives more protection.
Answer:
Natural selection is a adaptation process of evolution.
Explanation:
- As the battles are the most diverse type of insects on the planet they consist of about 400,000 or more species of them on the planet.
- They use camouflaged while others are easily visible and its due to this natural property that they acquired from the environment they can easily blend in with the natural features of the real world.
- Such as the barks or the branches of the tree. Some of them can chemically be camouflaged as well, mostly to avoid predators and keep them away.
The question is incomplete as it does not have the options which are:
- Adjusts the positions of the head, the neck, and the trunk
- Perform respiratory movements
- Stabilize or position parts of the appendicular skeleton
- All of the above
Answer:
All of the above
Explanation:
The axial skeleton is the group of bones which forms the centre of the skeletal system. The central portion of the skeletal system includes bones of the skull, bones associated with the skull, the thorax, and the vertebral column (spinal cord).
There are 80 axial skeletal bones out of which 22 bones are present in the skull, 7 attached to the skull, 25 in a thoracic cage and 26 in the vertebral column.
The axial skeleton help maintains the position of the appendicular skeleton, maintain the posture of the body by maintaining the posture of the neck, head and trunk and also help in the respiratory movements.
Thus, all of the above is correct.
