Which statement best describes the relationship of photosynthesis and energy?
The process of photosynthesis is energy-storing because the process converts light energy into chemical energy,
which is stored in the bonds of glucose.
The process of photosynthesis is energy-releasing because the process converts light energy into free energy that
can be used for cell functions.
The process of photosynthesis is energy-conserving because no energy is used throughout the process of forming
glucose and oxygen molecules.
The process of photosynthesis is energy-wasting because photosynthesis is an inefficient process that depletes
the cell of energy stored in the bonds of glucose.
on Edg
Answer:
A. The process of photosynthesis is energy-storing because the process converts light energy into chemical energy
Explanation:
I would say A because photosynthesis is a process in which uses light energy to split water molecules into hydrogen and water molecules, which means light energy is converted into chemical energy. And energy is also stored in the leaf temporarily as starch.

Suppose that an unusually high degree of aurora kinase activity is observed in the cervix. What could we reasonably conclude about C5M treatment efficacy across all cervical cancer cell lines, using this new information and the data within the passage
Answer:
The division of cervical cancer cells will be inhibited
Explanation:
Aurora kinases are a type of serine/threonine kinase enzymes that play critical functions during cell proliferation, and they are recognized to be potential targets in cancer therapy. The benzo[e]pyridoindole (C5M) agent is a hydrosoluble inhibitor of aurora kinases capable of inhibiting cell proliferation. C5M induces mitotic arrest by faulty (no separation) of the sister chromatids during cell division, thereby eventually leading to polyploidy and finally triggering cell death. It has been shown that C5M acts to prevent the entry in mitosis by inhibiting histone 3 (H3) phosphorylation of aurora kinases.

enlist the sources of nitrogen fertilizer
Answer: hope this helps....
Explanation: organic sources of nitrogen include alfalfa meal, which supplies 2 percent to 3 percent nitrogen and lasts approximately one-third of the year. Dairy and poultry manure also can release suitable amounts of nitrogen fresh or composted manure can also be from an acceptable organic source such as small independent farms.
Answer:
nitrogen is the main source of fertilization to plants
Explanation:
the main and big source of nitrogen fertilizers are atmospheric nitrogen which has to be converted into nitrates because plants cannot pick up the atmospheric nitrogen directly but now genetic engineering has produced plants that can fix nitrogen directly from environment its main source is nitrogen cycle
An ecologist hypothesizes that predation by a particular owl species is the major factor controlling the population of a particular rabbit species. The first step in testing this hypothesis would be to determine
Answer:
The correct answer is - whether owl eats the rabbits.
Explanation:
A hypothesis is a proposed answer for an unexplained event that doesn't fit into the current acknowledged logical hypothesis. The essential thought of a hypothesis is that there is no pre-decided result.
The Hypothesis can be proved or disproved by scientific research that has various steps but initiailly testing the hypothesis is essential:
- Making assumptions.
- Stating the research and null hypotheses
- Selecting the sampling pattern and specifying the test statistic.
- calculating the test statistic.
-Making a decision and interpreting the results.
Thus, the first step after forming a hypothesis is to check or test the hypothesis which is null hypothesis -whether owl eats the rabbits.
How would you conduct your investigation? In your answer, explain your independent and dependent variables
Answer:
The dependent variable is the growth rate of the plant. The independent variable is the type of fertilizer used over time. There will be three groups of tomato plants raised from seed: one group will be a control group without any fertilizer, the second group will be planted in soil with artificial fertilizer, and the third group will be planted in soil with compost. The height of the plants will be measured every five days, over a 30-day period.

Mutations in a gene occur at a rate of one nucleotide every 10 million years. The gene sequence differs by 6 nucleotides between two related organisms. How long ago did these organisms split from a common ancestor
Answer:
Total time split from a common ancestor = 30 million
Explanation:
Given:
Number of nucleotide = 6
Number of organism = 2
Rate one nucleotide = 10 million year
Computation:
Total time split from a common ancestor = [Rate one nucleotide / Number of organism]Number of nucleotide
Total time split from a common ancestor = [10 million / 2] 6
Total time split from a common ancestor = [5 million] 6
Total time split from a common ancestor = 30 million

A lichen is an organism that structurally appears to be a single organism. But a lichen is actually two different organisms—a fungus and green algae—living together as one organism. The fungal partner derives its nutrition from the photosynthesizing algae. How does a lichen differ in its photosynthetic activity from Elysia chlorotica, the sea slug that’s considered to be a photosynthesizing animal? A. In lichens, the fungi photosynthesize on their own, while Elysia chlorotica forms a relationship with a photosynthesizing plant. B. In lichens, the relationship with the algae lasts throughout the life cycle, but in Elysia chlorotica, the relationship occurs only during the immature juvenile stage of the slug’s life cycle. C. Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells. D. In lichens, the association between the fungi and algae is permanent, while Elysia chlorotica associates with a photosynthesizing organism only when it requires food.
Answer:
Option C
Explanation:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.
Elysia chlorotica which is a form of sea slug feeds on a specie of the genus Vaucheria (an algae) and then retains only the chroloplasts of these algae which it uses for its own supply of energy.
The algal partner in lichens is the photosynthesizing partner. It produces food and this is its role in the relationship. The fungi are heterotrophs and cannot photosynthesize food. The fungi contribute to the relationship my absorbing mineral and water and presents it to the algae.
Answer:
Lichens can photosynthesize only because of the living algal partner, while Elysia chlorotica incorporates chloroplasts from algae into its cells.

Which characteristic describes the whale but not its food source, the phytoplankton? The whale is heterotrophic. The whale has cell walls. The whale is unicellular. The whale is a prokaryote.
Answer:
A. The whale is heterotrophic.
Explanation:
The whale is an aquatic animal that is heterotrophic in nature. Heterotrophic means that this animal lacks the ability to manufacture its own food because it depends on plants and animals as a source of food energy. Since the Whale is dependent on phytoplankton for food, this means that it is not a producer of food and as such is heterotrophic.
Phytoplankton is a marine alga. Algaes are prokaryotes and this means that they are unicellular animals without a membrane-bound nucleus. The Cell wall is mostly a characteristic of plants. So the first option is a perfect description of the whale and not its food source which is the phytoplankton.
Answer:
ExplanationThe whale is heterotripic

If fossil species A is consistently recovered from geological deposits beneath layers containing fossil species B, then A is considered to be older than B. This relative dating technique is based on the principle of Group of answer choices fluorine analysis. paleomagnetism. geolayering. superposition.
Answer:
superposition
Explanation:
Dating consists of ordering geological events according to the time they occurred, which ones occurred first, and which ones occurred latterly. This dating can be done by using the superposition geological principle.
Sediments can be incrusted in horizontal layers in the ground, called stratum. Different stratum can give us information about the environment in the past. They keep information about the age and the conditions under which the sediments got deposited.
Some geological principles allow us to date, relatively, the age of different geological events in the past.
Sediment layers place in a temporal sequence, let us know that the older layers are located in an inferior position concerning the newer layers. Hence, fossil species placed in more inferior layers are supposed to be older than fossil species found in more superficial layers.

How do you think pollination takes place in flowering plants?
Answer:
My answer is down below.
Explanation:
Pollination occurs when the transfer of pollen grains from the anthers to the stigma of a flower of the same species take place. After reaching the stigma of the flower of the same kind of plant, the pollen grains absorb moisture from the stigma surface and begins to grow a tube. This tube is called the pollen tube.
Explanation:
insects typically pollinate flowers as they move from plant to plant searching for food. when an instects lands on a flower to feed, pollen grains sticks to its body. As the instects moves to another flower of the same species, these pollen grains are transferred to the flower's stigma and pollination occurs.
The epiglottis is a:_________.
a. muscle that moves the trachea out of line with the pharynx during swallowing.
b. flap of cartilage that flips down to cover the entry to the trachea during swallowing.
c. muscle that moves the esophagus in line with the pharynx during swallowing.
d. sphincter that closes off the entry to the trachea during swallowing.
Answer:
b. flap of cartilage that flips down to cover the entry to the trachea during swallowing
Explanation:
The function of the epiglottis is to prevent food and liquids from entering the windpipe (trachea) and the lungs. It is a flap of cartilage that stands upright when we breathe, allowing air to pass into the larynx and lungs. But while we are eating or drinking, it flips down over the opening of the trachea to prevent food and liquids from getting in there.

Which piece of evidence would strongly support the RNA-first hypothesis? finding a protocell that could carry on metabolism as well as reproduce discovering a way to make RNA more stable than DNA finding a mechanism whereby proteins could assemble DNA out of free nucleotides being able to build microspheres that contain only protein and RNA finding a living organism that uses RNA as its genetic material
Answer:
The correct answer is - finding a living organism that uses RNA as its genetic material.
Explanation:
The RNA world theory recommends that life on Earth started with a simpler form of RNA particle that could duplicate itself. The RNA world speculation recommends that life on Earth started with a basic RNA particle that could duplicate itself without assistance from different atoms.
The RNA world theory is upheld by RNA's capacity to store, transmit, and copy hereditary data, as DNA does. RNA can go about as a ribozyme, an uncommon kind of enzyme. Since it can play out the role of both DNA and enzyme, RNA is accepted to have once been equipped for supporting free living things.
According to the hypothesis is that RNA, a nearby relative of DNA, was the main hereditary atom to emerge around 4 billion years back, however in a simpler form of life that later developed into the RNA and DNA particles that we have in life today
Thus, The correct answer is - finding a living organism that uses RNA as its genetic material
