it is every organisms goal to "survive and repopulate" therefore, with natural selection the weaker organisms die because they did not possess the traits necessary to survive, and the strong survive and repopulate

Which of the following factors decrease biodiversity? (Choose all that apply)
a. habitat destruction
b. unpredictable precipitation
c. warm temperatures
d. freezing temperatures
Answer:
habitat destruction, unpredictable precipitation, and freeing temperatures.
Explanation:
i took the quiz
The destruction of the habitat, unpredictable precipitation, and freezing temperatures decreases biodiversity. Thus, options a, b, and d are correct.
What is biodiversity?Biodiversity is the variety of life that sustains on earth and lives in a particular habitat. The biodiversity can be measured based on the ecosystem, species, and genetics. It comprises the ecological and evolutionary process.
The destruction of the habitat of a species can lead to a decrease in biodiversity as it affects the ecosystem and the ecological pyramid as a whole and will affect the population of the species.
The unpredictable precipitation can affect the species and the habitat as it may lead to floods that will destroy the habitat hence resulting in the loss of species.
Similarly, the decrease in temperature will affect many species as they will not be able to cope with low temperature resulting in their death.
Therefore, the unpredictable precipitation, freezing temperature, and destruction of habitat lead to a decrease in biodiversity.

An isometric exercise is one in which the joint angle does not change during the application of muscle force. For instance, you can join your hands together, pushing down with one hand and pushing up with the other. In each arm, the muscles that provide the force are connected to the bones of the arm by tendons. If you increase the forces but keep the angles the same, the muscles will still contract. Explain how this is possible.

Explain the importance of using engine powered pump for irrigation works.
Answer and Explanation:
Engine irrigation pumps are used to propel water into the irrigation channels, providing full water supply to agricultural crops. The use of the engine pump has advantages and disadvantages. Among the advantages, we can present the simplicity of operation of these pumps, being easily operated efficiently. They also save energy and are essential for irrigation with more viscous liquids, when necessary. This feature is the main reason for using this type of pump.
Among the disadvantages we can say that these pumps have a slower and less accurate work.

explain how incomplete dominance differs from co-dominance
Answer:
Incomplete dominance is when the phenotypes of the two parents blend together to create a new phenotype for their offspring.
An example is a white flower and a red flower producing pink flowers. Codominance is when the two parent phenotypes are expressed together in the offspring

What are the two main ways bacteria cause illness?
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
C. By changing the genetic material inside your cells
D. By breaking down your cells for nutrients
Answer:
A. By releasing toxins that poison your cells
B. By using your cells to make copies of themselves
Explanation:
Within the body, bacteria can divide (multiply) and kill host cells by disrupting their normal functioning. Moreover, bacteria secrete toxins that are able to destroy host cells' metabolic machinery. For instance, many bacteria synthesize exoenzymes and interferons that disrupt and destroy host cells. Bacterial toxins can be synthesized internally in order to develop sensitivity through antigenic properties.

15. Suppose a human blood cell containing a 0.9 percent solute concentration were put into a container of 30 percent solute solution. Would the blood cell get bigger or smaller? Why? In your explanation, you must tell me which area has the hypotonic solution (inside the blood cell or outside the blood cell), which area has the hypertonic solution (inside the blood cell or outside the blood cell), and which direction the water would be moving (into the cell or out of the cell).
Answer:
Smaller
Explanation:
The human blood cell has a smaller percentage of solute concentration than the solution it was placed into. This means that the cell is hypotonic in comparison to the solution, and the solution is hypertonic compared to the cell. When a cell is placed in a hypertonic solution it undergoes crenation, meaning it shrivels up. Water moves from the lower solute concentration to the higher solute concentration. The water inside the cell moves outside to the hypertonic solution. This causes the cell to become smaller.

The disease multiple sclerosis makes it more difficult for signals from the brain and spinal cord to travel along nerve fibers. How will multiple sclerosis
affect other body tissues?
O Connective tissue will increase its fat storage.
O Muscle tissue will contract uncontrollably.
Epithelial tissue will lose the ability to protect against infection.
Tendons and ligaments will become brittle and break.
Answer:
O Muscle tissue will contract uncontrollably.
Explanation:
Multiple sclerosis, also known as encephalomyelitis disseminata, is a disease that affects the brain and spinal cord. Some of the most common symptoms of multiple sclerosis include vision problems, arm or leg movement and balance. This disease occurs when the immune system attacks the myelin sheath that covers nerve cells in the brain and spinal cord, causing inflammation and subsequent damage of the sheath and the nerve fibers it surrounds. Multiple sclerosis may cause muscle twitches when nerve fibers are damaged, thereby disrupting the signaling between nerves and muscles.
