You hang a swing from a live tree branch that is roughly parallel to the ground. What will likely happen over time as the tree grows? Check All That Apply
The swing will move farther away from the tree trunk. The swing will move up. away from the ground. The swing will remain in its original position. The swing's ropes will become embedded in the branch.Answer:
The swing's ropes will become embedded in the branch.
Explanation:
The trunk or branch strangulation sadly occurs very often. When people tie a young tree with different materials, such as a rope, or a cable, or a wire, and leave it there, the leash will eventually strangulate the tree.
Strangulation occurs because the tree keeps growing, applying pressure on the leash. The vascular system is in the trunk perimeter under the crust. Through the years, the pressure increases, the trunk is even more strangulated, and the vascular system is affected. One of the first and principal effects of strangulation is the increase in the trunk or branch diameter over the leash. This diameter change is because elements of the sap can not go back to the roots and keep near the strangulation. At this point, there are two options:
The tree can sort this by including the leash in its tissues, surrounding and absorbing it, and keep growing normallyor
The vascular system is so affected that the tree can not sort this problem and so, those parts of the tree located over the leash dye.In the exposed example, it seems that the tree could make it and included the swing's ropes in the branch.

Which crop leaves soil with the lowest levels of nitrogen?
Answer:
cotton
Explanation:
Cotton crop leaves soil with the lowest levels of nitrogen.
What is a nitrogen?Nitrogen is the chemical element with the symbol N and atomic number 7. Nitrogen is a nonmetal and the lightest member of group 15 of the periodic table, often called the pnictogens. It is a common element in the universe, estimated at seventh in total abundance in the Milky Way and the Solar System.
Nitrogen is important to the chemical industry. It is used to make fertilizers, nitric acid, nylon, dyes and explosives. To make these products, nitrogen must first be reacted with hydrogen to produce ammonia. This is done by the Haber process.
Nitrogen is important to all living things, including us. It plays a key role in plant growth: too little nitrogen and plants cannot thrive, leading to low crop yields; but too much nitrogen can be toxic to plants [1]. Nitrogen is necessary for our food supply, but excess nitrogen can harm the environment.

Why did the plant you put in freshwater stay fresh?
Answer:
To maintain its turgor.
Explanation:
The plant you put in freshwater stay fresh because the plant maintain its turgidity. Plants used water in the process of photosynthesis for making their own food as well as maintain its turgidity. Every cell needs specific amount of water to remain turgor, if the water is lost from the cell or plant, the plant becomes wilted so that's why by putting the plant in freshwater remain fresh.

B

microevolution
D
population genetics
Answer:
D. Population genetics
Population genetics is the study of genetic variation within populations, and involves the examination and modelling of changes in the frequencies of genes and alleles in populations over space and time. ... In natural populations, however, the genetic composition of a population's gene pool may change over time.
Explanation:
microevolution - evolutionary change within a species or small group of organisms, especially over a short period. (Not studying the overall evolution in the population, just a single allele usually) Not it then
macroevolution - Macroevolution in the modern sense is evolution that is guided by selection among interspecific variation, as opposed to selection among intraspecific variation in microevolution (this goes over huge groups of different species) Not it then
gene pool - The gene pool is the set of all genes, or genetic information, in any population, usually of a particular species. (Not the study of evolution in a population) Not that then
So it has to be D

What was the average of diameters (cm) for the Willapa Bay urchins sampled before the hunt? (Type just the number rounded to the tenth place and do not include units.)
Answer:
See Explanation
Explanation:
The question is incomplete as the diameters of the Willapa Bay urchins were not given.
However, I'll give a general way to solve this problem.
Average is calculated using:
[tex]Average = \frac{\sum x}{n}[/tex]
i.e. Sum of all diameters divided by the number of bay urchins.
The diameter of urchins is usually between 6cm to 12cm; So, I will assume the following diameters for 10 urchins.
10cm, 8cm, 10cm, 7cm, 9cm, 10cm, 6cm, 10cm,8cm, 8cm
Using the above data, the average is:
[tex]Average= \frac{10+8+10+7+9+10+6+10+8+8}{10}[/tex]
[tex]Average= \frac{86}{10}[/tex]
[tex]Average= 8.6[/tex]

Answer:
C. lowers the density of the water
Explanation:
Took k12 test got 100%
Hope this helps
A thunderstorm adds freshwater to the ocean as it lowers the density of the water. Thus, option B is correct.
What creates density variations in ocean water?
Differences in temperature and salinity that create density variations in ocean water and salinity refer to how much salt that the ocean water contain, and the temperature became a very important factor because it could determine the amount of water that evaporates.
The term thermohaline circulation is the mixing of hot and cold water from upper surface to the lower surface. This is caused by the temperature and salinity that changes in the water.
It is driven by the density gradient in which the thermohaline circulation begins when the temperature is very cold and ice forms in the sea. The surrounding sea water gets saltier and its density increases and it sinks down.
Therefore, A thunderstorm adds freshwater to the ocean as it lowers the density of the water. Thus, option B is correct.

Answer:

3. u did it right
Good job
The chemical symbol for chlorine is Cl. There are seven valence electrons present in chlorine.
What are valence electrons?
Valence electrons are electrons in an atom's outermost shell, or energy level. For example, oxygen contains six valence electrons, two of which are in the 2s subshell and four of which are in the 2p subshell.
The chemical symbol of the element (as found on the periodic table) is written in the Lewis symbol for an atom, and the valence electrons are depicted as dots encircling it.
The number of electrons in an atom's outermost shell is referred to as its valence electrons. The final shell of the chlorine atom now has 7 electrons. As a result, a chlorine atom contains 7 valence electrons.
Therefore, Cl is the chemical symbol for chlorine. In chlorine, there are seven valence electrons.
