Red team
Which action is most likely to make the team on the left win?
A. Adding one student to the team on the right
B. Instructing both teams to pull a little less so that each side is
applying only 50 N of force
C. Adding one student to the team on the left
D. Instructing both teams to pull harder so that each side is applying
150 N of force
Answers
Answer: C) adding a person on the left
This additional person will pull more force to the left side and help that team win the tug-of-war.
Choice A is the complete opposite of what we want, since it helps the red team win. Choices B and D won't change the current state because the same thing is happening to both sides. So we can rule out choices A, B and D.

The upper mantle of Earth is a very thick layer of rock inside the planet, which begins just beneath the crust (at about 10 km (6.2 mi) under the oceans and about 35 km (22 mi) under the continents) and ends at the top of the lower mantle at 670 km (420 mi). Temperatures range from approximately 200 °C (392 °F) at the upper boundary with the crust to approximately 900 °C (1,650 °F) at the boundary with the lower mantle. Upper mantle material which has come up onto the surface is made up of about 55% olivine, 35% pyroxene and 5 to 10% of calcium oxide and aluminum oxide minerals such as plagioclase, spinel, or garnet, depending upon depth.

This regulation also include brain and nervous system development, reproductive system growth and function, metabolism, and blood sugar level.
The endocrine system and the nervous system collaborate to influence many aspects of human behavior, together with growth, reproduction, and metabolism. And the endocrine system is crucial in the regulation of emotions.
In response to a stimulus, the nervous system basically signals the endocrine system to release hormones.
Thus, A is the correct option.

4) Discuss how our lives on Earth are directly related to our relationship and positioning with the Sun in our Solar System.
Answers
Answer:the relationship with the sun and the solar system is the same relationship to all physical bodies in which we are living at a speed governed by our perception at our vantage point in relation to how much gravity is acting upon us. Example: Say you were to fall into a black hole. At the point of no return at the event horizon your time would begin to slow down as seen from an outsider watching you fall. This will occur until to that observer sees you stop entirely in time. You however fall faster as faster but for ever. Till time is over. So all things are relative to each other in only one absolute way. Gravity control observed time.

When might self-fertilization be beneficial for a plant? When there are too many dioecious individuals in a population, self-fertilization becomes beneficial for a monoecious individual. When environmental conditions are harsh, such as a plant growing in nutrient-poor conditions, or when herbivores have damaged the plant, plants may self fertilize. When environmental conditions are perfect, plants can afford to self-fertilize. Only plants with perfect flowers are capable of self-fertilization.
Answers
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.
A Endometriosis is a condition that occurs in some women , causing multiple cells or layers of cells to grow outside of the uterus.
