Question 1 Which statement is true about fossils? O A fossil is any trace of prehistoric life. 0 To officially be a fossil, the remains of an entire organism must be found. O The remains of an organism that lived 500 years ago is called a fossil. Only the remains of animals. and not plant, can be made into a fossil. Question 2
Answers
Answer: The remains of an organism that lived 500 years ago is called a fossil.
Explanation:
A fossil can be defined as dead remains of plants and animals that existed past geological era. The traces of bones, and other skeletal remains, pollen, hard wooden materials can be found in the compact rock as the soft parts of the organisms are decomposed and decayed. The remains like shells, exoskeleton, amber, hair, and other can also be found. It takes many years for the development of fossil beneath the earth crust. The morphological, anatomical, physiological and molecular features can be assessed to know the age of the fossil.
Answer:
fossil is any trace of prehistoric life

Historically many ideas concerning cells have been examined leaving three to be incorporated into the cell theory which of the following is not part of the cell theory
Answers
Answer:all life form contains more than one cell
Explanation: thats the only question that's not true
Historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.
What is the significance of the theory behind the cell?Cell theory, a foundational concept in biology, states that all living organisms are made of cells, and these cells come from pre-existing cells and not from anywhere else. All these postulates support the idea that cells are the basic building blocks of life and that life can only be generated through the replication process.
Hence, historically, many ideas concerning cells have been examined, leaving three to be incorporated into the cell theory except that all life forms are made up of more than one cell as the life forms can either be single or multicellular.

Using the diagram as a guide, create a Punnett square to show a cross between Jason's father, who has brown hair, and Jason's mother, who has blonde hair (Hint! Jason's father's mother has blonde hair).
Explain the process of completing the Punnett square for Jason's parents. Be sure to correctly use the vocabulary terms Punnett square, genotype, phenotype, dominant, recessive, and alleles.
Based on the Punnett square, what is the probability that Jason would have brown hair?
Answers
Answer:
50% probability of brown hair.
Explanation:
Jason will have an 50% probability of having brown hair, brown hair is a dominant trait meaning Jason's fathers father had a brown phenotype as well since his mother had blonde phenotype. Causing Jason's father to have a genotype of of Bb, B is dominant brown phenotype and b is recessive blonde phenotype, and since Jason's mothers genotype is recessive b the possible genotypes are Bb, Bb, bb, bb so Jason has a probability of 50%.

. The principal site of protein synthesis in a cell is
a. Endoplasmic reticulum
C.
Ribosomes
b. Nucleus
d. Golgi - Apparatus
a.
Answers
Answer:
b. Nucleus
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;
1. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.
2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.
3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.
4. Chromosomes : they give sets of instructions for the synthesis of products.
5. Ribosomes : they are involved in the build up of proteins.
6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.
7. Cytoskeleton : they help to maintain and support the shape of the cells.
8. Vesicles : they ensure proteins are properly transported to the right and exact location.
9. Golgi apparatus : it prepares the protein for export by chemically tagging them.
10. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.
Hence, the principal site of protein synthesis in a cell is nucleus.

Based on knowledge of enzymes and the given data, it can be concluded that Tcn-protease is most likely active in the alligator's stomach and Wx-protease is most likely active in the alligator's intestines. As clear from the graph, the enzymic activity for Tcn-protease is highest at an acidic pH, which means it works best in an acidic environment, such as the very acidic stomach of an alligator. It is additionally clear from the graph that the enzymic activity for Wx-protease is highest at a neutral pH; therfore, it is most likely to be found in a neutral environment, such as the alligator's intestines.

- dispose waste properly and clean up area when finished.
-do not consume any chemicals or substances

These rules are put in place for the learning environment because it ensures the safety of all persons in the lab and prevents any accidents from happening such as injuries and dangers. They also prevent dangers such as cross contamination and explosions from occurring.
A class without lab safety rules would be extremely dangerous and even deadly. People would get injured and many hazardous risks would come up. (like cross contamination, explosions, mentioned above). Injuries like blindness, burns, and cuts can occur. Just imagine a class of 2nd graders with no teacher around. that’s kind of like a lab without safety rules :)

2. In the diagram below, west is to the left, east is to the right, and the observer is looking toward the north. What is the direction of the wind?
A. NE
B. NW
C. SE
D. SW
Answers
Answer: SW
Explanation:I got it wrong and it gives you the right answer so thats that
The direction of wind is SW direction. Hence option D is correct.
What is wind?Wind is defined as the air movement brought on by the Earth's rotation and the sun's uneven heating of the surface. The uneven heating of the Earth by the sun and the rotation of the Earth result in wind, which is the movement of air. Light breezes to natural disasters like hurricanes and tornadoes are all types of winds. In addition to being a plentiful and limitless resource, wind also generates power without consuming any fuel or polluting the environment.
An anemometer can measure wind speed, and a weather vane or wind vane can detect wind direction. When put with anemometers, many wind vanes can be installed in numerous locations to calculate the overall wind profile of a specific area.
Thus, the direction of wind is SW direction. Hence option D is correct.
