Answer:
The correct answer is - option A. 0%
Explanation:
The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.
The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.
percentage of chloroplast gene inherited from R plant is a)0%

How is the function of NAD
similar to that of NADP+?
Answer:
The function of NAD+ that is similar to that of NADP+ is that each NAD+ accepts a pair of high-energy electrons. Describe glycolsis in terms of energy input, energy output, and net gain of ATP. In glycolysis, glucose is converted to molecules of pyruvic acid. ... NAD becomes NADH.
Explanation:
Answer:
they are both electrons that carry high energy electrons which then are converted and used into the transport trains.

3 ways soil is important for plant growth.
Answer: Soil carries out a range of functions and services without which human life would not be possible. It provides an environment for plants (including food crops and timber wood) to grow in, by anchoring roots and storing nutrients. It filters and cleans our water and helps prevent natural hazards such as flooding.

what two things can happen to the food made by plants?
Answer:
Food made by plants can get used by plants or by other animals as plants maybe eaten by other organisms that feed on plants by living on them, these organisms are called parasites. Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration
Answer:
The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide
The food produced by the plants is in the form of sugar and the extra sugar produced is changed to starch and is stored in different parts of the plant such as in roots, stems, leaves, fruits and flowers.

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? Select all that apply.
Complete question:
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.

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.
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]

What is the name for the science that studies evolution that oc-
curs within a population?
A
gene pool
B
macroevolution
с
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

Living organisms need energy to carry on their life processes. Green plants get this energy by undergoing photosynthesis.
During photosynthesis, plants absorb energy from sunlight, they take in water from the soil using their roots, and they take in carbon dioxide from the atmosphere. What is produced in the leaves of plants, in addition to oxygen?
Question 4 options:
A. sugar
B. minerals
C. hydrogen
D. all of these
Answer:
A.sugar
Explanation:
In the process of phorosynthesis, the plants absorb energey from the sunlight, and with the water they have in the soil and the carbon dioxide they can absorb from the air, they´d produce carbohydrates or sugar and oxygen, in the chemical process of photosynthesys 6 molecules of water are mixed with 6 molecules of carbon dioxide, with addition of solar energy and form 6 molecules of sugar and 6 molecules of oxygen.

Raises the temperature of the water
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.
