How would the introduction of a predator species affect the stability of an
ecosystem?
A. The native prey might not be able to protect itself against the new
predator, so the prey population would probably decline rapidly.
B. The stability would not change because the new predator would
simply replace the native predator.
C. The new predator would be unable to hunt effectively for native
prey, so the stability would not change.
D. The stability of the ecosystem would increase as a result of the
introduction of a new predator species.

. The principal site of protein synthesis in a cell is
a. Endoplasmic reticulum
C.
Ribosomes
b. Nucleus
d. Golgi - Apparatus
a.
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.

Answer:
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.

Q4: Describe how crossing over can lead to new variations in genes.
Answer:
Crossing-over is the exchange of genetic material between homologous chromosomes. It results in new combinations of genes on each chromosome. When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.

A. NE
B. NW
C. SE
D. SW
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.

Two receptors bind to a same chemical messenger, but the concentration of this chemical messenger required to reach a certain number of bound messengers for one receptor is twice as great as the concentration for the other receptor. Thus, these two receptors have same ________, but different ________, to this chemical messenger
Answer:
binding specificity; affinity
Explanation:
Receptor binding specificity can be defined as the selectivity of a receptor to bind with a particular chemical messenger. Binding specificity is determined by the interaction between the chemical messenger and its specific receptor, as well as the binding site three-dimensional (3D) structure of both. This concept is contrary to receptor promiscuity, where a receptor can bind to many different chemical messengers. On the other hand, binding affinity can be defined as the overall affinity or avidity of binding. The binding affinity is determined by the accumulated strength of individual attractive forces between a chemical messenger (ligand) and its receptor.

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
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?
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%.
