2) The diagram below represents a change in guard cells that open and close pores in a plant. Guard cell Open pore Closed pore This change directly helps to A) regulate water loss B absorb minerals C) increase heterotrophic nutrition D) reduce seed production
Answers
Answer:
A) regulate water loss
Explanation:
Guard cells refer to the cells enclosing each stomata. They assist in monitoring the rate of transpiration by closing and opening the stomata. The guard cells possess the tendency to monitor the closing and opening of stomata by changing shape. The shape of the guard cells modifies on the basis of the concentration of potassium ions and water found in the cells themselves.
The stomatal pores get closed when carbon dioxide is no longer needed for the process of photosynthesis. The guard cells swell when movement of water takes place inside these pores, and thus, the opening of stomatal pores occurs, and as water moves out, the guard cell closes. Thus, guard cells play an essential role in regulating water loss.

Explain the shoot system and root system of a plant. Include roots, xylem, phloem, leaves, reproductive system, stomata, chloroplast, etc...
Answers
Answer:
The shoot system is above ground and includes the organs such as leaves, buds, stems, flowers (if the plant has any), and fruits (if the plant has any). The root system includes those parts of the plant below ground, such as the roots, tubers, and rhizomes.
Explanation:
Answer: The root system consists of the roots, while the shoot system is made up of the stems and leaves. The shoot system conducts substances up and down the plant; the root system stores food and retrieves nutrients from soil. Stems, leaves, fruits and flowers make up the shoot system. The leaves are the main photosynthetic organs of the plant. The stems hold the plant up and contain the xylem and phloem.

what Dr. Bailey and his team would find between these plates?
Answers
Answer: Diagram A: Soft, solid rock from underneath the plates rose and hardened adding solid rock to the edges of both plates.
Explanation:
Sand makes up the top layer of the Earth's crust under the ocean. The outer layer of the Earth is composed of solid, hard rock, beneath both the soil and the water. Thus, option A is correct.
What solid rock from underneath the plates?Underneath the sand and gravel on the surface is a solid, hard rock known as the bedrock. Bedrock also provides stability for the sand and other sediments that make up the ocean floor.
The rigid, stony, outermost layer of the Earth is referred to as the crust. It is composed of low-density, easily melted rocks; the continental crust is mostly composed of granitic rock, while the oceanic crust is primarily composed of basalt and gabbro (see granite).
Therefore, Soft, solid rock from underneath the plates rose and hardened adding solid rock to the edges of both plates.

How does a lack of dissolvable oxygen in waterways affect aquatic biodiversity?
Answers
Answer:
I think ‘there will be less oxygen available for the aquatic life due to the microbial activity’. Too much microbial activity utilizes the oxygen dissolved in the water hence making the waters anoxic. This occurs especially after algae blooms. When the algae grow exponentially and later die, microbes that oxidize the organic matter for energy utilize the oxygen and cause dissolved oxygen in the water to deplete. This hence suffocates other aquatic life.
(This is what my sister sayed so I put it down)
Explanation:
answers: When dissolved oxygen becomes too low, fish and other aquatic organisms cannot survive.
explanation: The colder water is, the more oxygen it can hold. As the water becomes warmer, less oxygen can be dissolved in the water.

Relative dating and radiometric dating are used to determine age of fossils and geologic features, but with different methods. Relative dating observes the placement of fossils and rock in layers known as strata. While Radiometric dating, or numeric dating, determines an actual or approximate age of an object by studying the rate of decay of radioactive isotopes
Suppose that the same island experiences environmental conditions that prevent the growth of large seeds. What do you think would happen to the average size of finch beaks. Explain your reasoning.
Answers
Answer:
would be smaller
Explanation:
During his work, Darwin observed that the size and shape of finches' beaks varied between islands as a consequence of the food type and food availability in each island. Darwin proposed that this phenotypic variation was a response to natural selection, i.e., those organisms with more suitable beaks in their corresponding environments (i.e., islands) would be better adapted to survive and reproduce, thereby passing their genes to the next generations. In consequence, in this case, it is expected that the average size of finch beaks will be smaller because environmental factors prevent the growth of large seeds.

The species of tree shown below grows in a wide range of temperatures in a desert area in Africa, where average temperatures have been rising over the past several
decades. The trees in the hottest parts of their range are dying, but trees at high elevations or in parts of the range that are cooler are growing and reproducing.
If this warming trend continues, which of the following statements best describes how the reproduction of trees will affect future generations of the species?
A. Trees in hotter regions will likely not survive and those at higher elevations will live to reproduce and pass their traits on to the next generation
B. The trees will adapt to the higher temperatures out of need and have offspring that are better suited for hotter temperatures.
C. Mutations in the somatic cells of individual trees that allow for resistance to heat will be passed along to future offspring.
D. Trees will adapt a method of dispersing seeds to higher elevations
Answers
Answer:
Explanation:b
Trees in hotter regions will likely not survive, and those at higher elevations will live to reproduce and pass their traits on to the next generation. This process is called as natural selection. Therefore, the correct option is A.
What is natural selection?Natural selection refers to the process through which the populations of the living organisms adapt and change to the changing environmental conditions.
In the scenario given here, if the warming trend continues, trees in hotter regions will likely not be able to survive due to the heat stress. Over time, the surviving individuals will pass on their traits to their offspring, resulting in a population better adapted to the warmer temperatures.
Option B is less likely because adaptation to higher temperatures can take a long time. Option C is incorrect because somatic mutations are not passed on to offspring. Option D is also unlikely, as it requires a complex change in behavior, and it's not clear if the species is capable of such adaptation. Therefore, the correct option is A.

Carbon dioxide. We read about the excess of carbon dioxide in the atmosphere and now it may be influencing our climate. But the oceans currently absorb about a third of human created a carbon emissions about 22 million times a day. The oceans have always been a carbon dioxide store house as the illustration shows. But this huge influx of carbon is changing the oceans. What is one change that would expect to happen
Answers
Answer:
Increase the pH of water.
Explanation:
One change that would expect to happen the increase in pH of ocean water because carbondioxide gas is dissolved in water make it acidic. This acidic water greatly affect the marine animals such as oysters and corals whose shell is dissolved due to acidic nature of water so we can say that carbondioxide gas increases the pH of ocean water.
