explain why a plant that does not get enough nitrate has weak growth
Answer:
Nitrate deficiency
Explanation:
Plants absorb nitrates in water through their roots. Nitrates are present in high levels in plant fertilisers. Without nitrates, the amount of chlorophyll in leaves reduces. This reduces the plant's ability to photosynthesise and grow properly, which reduces the farmers' crop yield .
1. What is the independent variable in this experiment?
Answer:
Variables are given a special name that only applies to experimental investigations. One is called the dependent variable and the other the independent variable. The independent variable is the variable the experimenter manipulates or changes, and is assumed to have a direct effect on the dependent variable.
Explanation:
Answer:
The independent variable is the factor that doesn't rely / change based on another variable. Usually there is an independent, dependent, and constant variable. The dependent variable's "results" and values rely on the independent value.
For example if tomatos were to be grown the independent variable is the type of light the tomato plant is grown under. The dependent variable would be the rate of the growth of the tomato plant. (It relies on the type of light, the independent variable)
when a vegetable gets put in salt water and collapses why does this happen
Osmosis is defined as the movement of solvent (like water) from a region where the concentration of solute(like salt) is lower to a region where the concentration of solute is higher through a semipermeable membrane.
Salt water is a hypertonic solution as the concentration of salt ( solute) is higher. Therefore, in this case water from vegetable will move outside causing the cells to become fragile.

The graph below shows changes in the populations of two species that interact only with each other over a period of time.
Which statement best describes these two species?
Species A is a producer and species B is its consumer.
Species A is a host and species B is its parasite.
Species A is a predator and species B is its prey.
Species A is a scavenger and species B is its decomposer.
The statement that best describes the two species depicted in the graph is option C) Species A is a predator and species B is its prey.
Option A indicates that species A is a producer and species B is its consumer. This means that species B requires the output from species A to survive. Knowing this, we would expect to show that species B increases in population as the population of A increases, due to increased food supply, the graph shows the opposite scenario. Thus, option A is false.
Option B states that perhaps Species A is a host and species B is its parasite. This provides the same conditions and dependencies as option a, so for the same reasons that a is false, we can conclude that option B is false as well.
The final incorrect option is D, Species A is a scavenger and species B is its decomposer. This would mean that as the population of species B dies off, it increases the food supply of Species A which feeds on the decomposing members of species B. We would expect in this case, that species A would flourish as B dies off, however, we see that as species B dies, species A follows shortly after. This tells us that option D is incorrect.
The correct option is C, Species A is a predator and species B is its prey. This would mean that species A consumes the members of species B to survive. Therefore we would expect to see
Species B thrive as the population of A remains lowFollowed by the steep decline of species B's population as more predators begin to appear. Once the population of species B reaches a critical point, species A will not have enough food supply to sustain its population, and both populations would decline.
This is exactly what the graph depicts, so option C is correct.

which of the following best describes how the population evolved ?
Answer:
The population has evolved because there was a change in allele frequencies.
Explanation:
Suresh and Gail are students in a lab working on mice with defects in the function of the HOX3A gene. In the special mouse line they are working on, no sequence changes are present in the genomic DNA of HOX3A, but the gene is not expressed properly and a mutant phenotype results. In one mouse line, an mRNA is produced in normal amounts, but no HOX3A protein can be detected.
Suresh thinks the absence of protein results from a change in RNA processing that prevents the inclusion of an exon in the final mRNA. Gail thinks the absence of protein results from some second gene that produces a protein that binds to the 3'UTR. Which of the two could be correct?
A) Only Suresh could be correct.
B) Only Gail could be correct.
C) Both Suresh and Gail could be correct.
Answer:
C) Both Suresh and Gail could be correct.
Explanation:
The pre-messenger RNA (pre-mRNA) transcript obtained after transcription of eukaryotic genes must undergo several processing events, including a process known as intron splicing, where introns (i.e., the non-coding sections of an RNA transcript) are removed and exons (coding regions) are joined to form a mature mRNA molecule. The three prime untranslated (3′-UTR) region of this mRNA can also bind to regulatory non-coding RNAs such as, for example, miRNAs which inhibit gene expression by inhibiting translation and/or by triggering its degradation. Moreover, the 3′-UTR region may also contain silencer sequences that bind to repressors in order to inhibit gene expression. On the other hand, translation refers to the process by which an ordered polypeptide chain (i.e., a protein) is synthesized by using the information contained in an mRNA molecule. In consequence, in the case under consideration, the mutation in the second gene could affect both RNA processing and the regulation of translation, thereby equally affecting HOX3A protein synthesis.
Describe the traits that would have existed in early eukaryotes.
Answer:
Early Eukaryotes were single-celled organisms that were present more than 1.6 to 2.1 billion years ago.
Explanation:
-Eukaryotes could be found in a variety of shapes and had a nucleus, a flexible membrane, and a cytoskeleton.
-Early eukaryotes used oxygen in metabolism.
Answer: Many traits found in eukaryotic cells today would have been found in early eukaryotic cells. First, early eukaryotic cells would have had membrane-bound organelles. Also, DNA probably contained introns since this is seen in many eukaryotic cells today. Chromosomes were probably linear in shape. Lastly, these cells would have had mitochondria and membrane-bound organelles. Since these are seen in all eukaryotic cells today, we can infer that they would have been around in early eukaryotes as well.

what are the names of the three domains
A.bacteria,archaea,eukaryotic
B.bacteria,archaea,animalia
C.archaea,plantista,animalia
D. Life,animals,plants
Answer:
A. bacteria, archaea, and eukaryotic.
Explanation:
Bacteria, archaea, and eukaryotic are the three domains of life.
The three domains system was globally implied. The three domains were Archae, Bacteria and Eukarya. The correct answer is option A.
The three domains of Carl Woese's categorization system are archaea, bacteria, and eukaryotes. The six kingdoms are archaebacteria (ancient bacteria), eubacteria (actual bacteria), protozoa, fungi, plants, and animals.
This classification system divides life into several groups based on differences in the 16S ribosomal RNA (rRNA) structure, the lipid composition of the cell membrane, and antibiotic sensitivity. The main distinction from earlier classification schemes is the division of Kingdom Monera into Archaea and Bacteria.
Therefore, the names of three domains given by Carl Woese were Archae, Bacteria and Eukarya i.e. option A.

Biology is the scientific study of life.[1][2][3] It is a natural science with a broad scope but has several unifying themes that tie it together as a single, coherent field.[1][2][3] For instance, all living organisms are made up of cells that process hereditary information encoded in genes, which can be transmitted to future generations. Another major theme is evolution, which explains the unity and diversity of life.[1][2][3] Finally, all living organisms require energy to move, grow, and reproduce, as well as to regulate their own internal environment.[1][2][3][4][5]
Biology deals with the study of life and organisms.

Biologists are able to study life at multiple levels of organization.[1] From the molecular biology of a cell to the anatomy and physiology of plants and animals, and to the evolution of populations.[1][6] Thus, there are multiple subdisciplines within biology, each defined by the nature of their research questions and the tools that they used.[7][8][9] Like other scientists, biologists use the scientific method to make observations, pose questions, generate hypotheses, and perform experiments to satisfy their curiosity about the world around them.[1]
Life on Earth, which emerged before 3.7 billion years ago,[10] is immensely diverse. Biologists have sought to study and classify the various forms of life, from prokaryotic organisms such as archaea and bacteria to eukaryotic organisms such as protists, fungi, plants, and animals. These various living organisms contribute to the biodiversity of an ecosystem, where they play specialized roles in the exchange of energy and nutrients.

Some kidney diseases cause a change in the permeability of glomerular capillaries making them more permeable to plasma proteins. This changes the colloid osmotic pressure, thus drawing water out of the blood and into tissues. The result is
Answer:
The correct answer is edema.
Explanation:
When the capillaries or the tiny blood vessels within the body leak fluid, the condition known as edema takes place. This fluid accumulates in the tissues surrounding it, resulting in inflammation. Edema generally takes place due to mild conditions like consuming more salt, staying or sitting in one position for a long duration, and others.
However, in some situations, edema can also be a sign of an extreme medical condition like kidney disease. During kidney disease, the sodium and additional fluid within the circulation may result in edema. The edema related to kidney disease generally takes place around the eyes and in the legs.
