Which is a vascular tissue in plants?
A. phloem
B. fungi
C. leaves
D. roots
Answers
Answer: Phloem
Explanation: In higher plants, the phloem is a vascular tissue that carries sugars and other nutrients synthesized from the organs that produce them, to those in which they are consumed and stored. The phloem is organized in vascular bundles (see image below) , which are longitudinal filaments of the conductive tissue associated with the water-conducting tissue or xylem. The vascular bundles are important structural organs of the herbaceous stems and the leaf nerves.

A new drug requires FDA approval, which involves rigorous processes including animal studies, human clinical trials, and submitting an NDA that includes comprehensive details on drug safety, effects, and administration.
For a new drug to be marketed, it is required to obtain FDA approval, which is a stringent process. Initially, manufacturers must conduct animal studies and human clinical trials to assess toxic dose levels before filing a New Drug Application (NDA). The NDA includes detailed information on drug usage, side effects, and possible drug interactions. Furthermore, it lays out guidance for how the drug should be manufactured, packaged, monitored, and administered. Patients and healthcare providers are informed about the drug's potential harmful side effects through labeling, package inserts, and publication in resources like the Physicians' Desk Reference (PDR), as well as through direct-to-consumer marketing efforts.
To proceed with clinical trials, researchers must submit an Investigational New Drug (IND) application to the FDA's Center for Drug Evaluation and Research (CDER) and wait for a 30-day review period. Should any problems arise before or during trials, the FDA has the authority to place a 'clinical hold' on the research. After successful clinical trials demonstrating the therapy's effectiveness and safety, the developers can then submit the extensive NDA for final approval.

If the nucleus of a cell was removed the cell wouldn’t be able to make proteins because
Answers
The nucleus contains the cells DNA(genetic material) which is basically the recipe for making proteins. mRNA is first transcribed off of DNA and then in translated(by ribosomes) to polypeptides(proteins).
If the nucleus of a cell was removed the cell wouldn’t be able to make proteins because no matter proteins are manufactured by the ribosome which is present in cytoplasm, the mrna needed for proteins synthesis is manufactured inside the nucleus.
How are proteins made inside the nucleus?Translation is the mechanism used to create new proteins. During transcription, DNA is converted into a messenger RNA (mRNA) molecule. The mRNA formed inside the nucleus then needs to be translated into a protein. To generate proteins, ribosomes, transfer RNA (tRNA), and mRNA collaborate during translation.The three phases of translation are essentially the same, but they go by more elegant names: initiation, elongation, and termination. The ribosome joins the mRNA and the first tRNA at the initiation ("starting") stage, allowing translation to start.learn more about nucleus here:

Vegetative reproduction is any form of ASEXUAL reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or a specialized reproductive structure.
Many plants naturally reproduce this way, but it can also be induced artificially.
Answer:
The correct answer option is B. vegetative reproduction.
Explanation:
Some plants can reproduce without involving fertilization. This process allows plants to grow much faster and is known as vegetative reproduction.
Vegetative reproduction is a type of asexual reproduction in plants which means that only one plant is able to produce an offspring on its own.
Since there is no involvement of another plant to reproduce, therefore this process is faster than sexual reproduction.

Answers
Answer:
composition of meteorites
Explanation:
The continental drift theory has been based upon several evidence. The shape and perfect fit of South America and Africa is one of those evidence. The fossil records are another very strong evidence, as there are fossils of the same species on different continents that are not connected to each other in the present, and in nature is practically impossible to have the same species in different continents. The evidence about the climate also suggests that the continents have been moving, as there are remains of glaciers at places that nowadays are deserts and savannas. The meteorites are not one of the evidence though, and their composition doesn't have anything to offer in this tehory, as their composition is not related to the Earth and the processes on it.

Streams erode their channels by abrasion, by dissolving soluble material, and by _____. layering polishing grinding evaporation
Answers
Answer:
grinding
Explanation:
The streams are very powerful agents when it comes to erosion. With their power and chemical composition, the streams manage to erode the rocks easily and even the hardest rocks experience significant changes or are totally destroyed over time. The water of the streams manages to break down the rocks into small or big pieces, and as it does it moves them away. The rocks that are carried are constantly colliding with other rocks along the way, causing even more pieces to break and to be eroded, thus the grinding type of stream erosion.
Answer:
The correct answer is grinding.
Explanation:
The ability of a water stream to erode and transport materials that it has collected from the ground during the water cycle depends largely on the speed with which it moves. A current channel is the direction in which water moves in a current.
These currents perform erosion by lifting loose particles by abrasion, and grinding and dissolving the soluble material they collect. The faster the water moves and produces greater turbulence, it will produce greater erosion.
The three ways to transport sediments during this cycle are: in solution, in suspension and sliding or rolling along the bottom.

Although air is full of nitrogen, it is not available for organisms to readily use.
Nitrogen is changed into which substances before being used by living
things?
Answers
Answer:
Nitrogen is changed into AMMONIA, NITRATES AND NITRITES before it can be used by living things.
Explanation:
Nitrogen is the most abundant element in the atmosphere, approximately 78% of the air is made up of nitrogen. Despite the abundance of nitrogen, the element can not be used directly by plants and animals.
Nitrogen fixing bacteria that are found in the soil are the ones responsible for converting atmospheric nitrogen into the forms that can be used by plants. Nitrogen fixing bacteria convert atmospheric nitrogen to ammonia while nitrifying bacteria convert ammonia to nitrates and nitrites. Plants use ammonia, nitrates and nitrites to make organic molecules.
All living organisms use nitrogen to make various compounds such as DNA, proteins, chlorophyll, etc.
After the death of the living organisms containing the nitrogenous products, dentrifying bacteria decompose the nitrates in their body to atmospheric nitrogen.

Water passes from one living organism to another when:
A. an ocean wave splashes onto a beach.
B. a person sweats during exercise.
C. an animal eats the leaves of a plant.
D. a plant absorbs nutrients from the soil
Answers
A. There is no exchange of water between organisms.
B. A single organism is excreting fluid. This will then evaporate into the atmosphere. No exchange takes place.
C. An animal consuming an organism involves two organism that both contain water. One absorbs the other’s water through digestion.
D. A plant absorbs nutrients from the soil. This could also be correct as there are organisms in the soil losing water through decay. However those organisms aren’t identified in the statement. This means that C. is the best answer.
Water is transferred from one living organism to another when an animal eats the leaves of a plant, incorporating the water contained in the plant into its own biological system. This is a direct transfer of water as opposed to processes like transpiration or ocean upwelling, which are part of the larger water cycle but are not direct transfers between living organisms. Hence, the correct option is C.
The correct answer to the question would be when an animal eats the leaves of a plant. During this process, water that was absorbed by the plant and exists within the leaves is transferred to the animal. This reflects an aspect of the water cycle where water is moved between different trophic levels within an ecosystem.
On the other hand, the transpiration process involves plants taking up water through their roots, which then moves up the plant and evaporates from the leaves, returning water back to the atmosphere, rather than directly to another living organism. Ocean upwelling is another related concept where nutrients, once part of organisms that have died, are brought back to the surface and made available again for other living organisms through the action of winds and water currents. However, it does not directly involve the passage of water from one living organism to another in the immediate sense.

why are bacteria needed in the nitrogen cycle
Answers
Bacteria, particularly cyanobacteria and rhizobia, play a crucial role in the nitrogen cycle through the process of nitrogen fixation. They convert inaccessible atmospheric nitrogen into a usable form (ammonia) for plants and animals, acting as natural and sustainable fertilizers. This process allows nitrogen to be incorporated into proteins and nucleic acids, supporting growth in terrestrial ecosystems.
Explanation:Bacteria play a vital role in the nitrogen cycle, particularly through a process known as nitrogen fixation, a biological process where atmospheric nitrogen (N₂) is converted into ammonia (NH3). Some bacteria like members of the genus Rhizobium and cyanobacteria perform this independently, while others, collectively known as rhizobia, interact symbiotically with legume plants to assist in nitrogen fixation. These bacteria, housed in specialized structures called nodules on legumes, convert atmospheric nitrogen into a form that is usable by plants and animals, essentially acting as a natural and sustainable fertilizer.
Nitrogen becomes incorporated into the proteins and nucleic acids of the organisms, leading to growth and development. The nitrogen fixation process is particularly vital as the nitrogen available in the atmosphere cannot be used directly by most living organisms. Therefore, through the conversion of atmospheric nitrogen to ammonia, these bacteria make nitrogen accessible and usable for terrestrial ecosystems.
