Answer: Autotroph, producer
Explanation: The grass gets eaten by primary consumer starting the food chain
In a food chain, the grass is referred to as an autotroph and producer. Therefore, option D is correct.
What are autotrophs?An organism is referred to as an autotroph or primary producer when it uses carbon from simple substances like carbon dioxide to create complex organic compounds. These creatures often obtain their energy from inorganic chemical reactions or light.
Both plants like blue-green algae and microorganisms like cyanobacteria are assumed to be autotrophs. Most plants are autotrophs because they create their own food through photosynthesis. But there are always exceptions to the norm. Some plants are parasitic and non-photosynthetic, getting their nutrition from a host.
Thus, the grass in a food chain is described as autotroph and producer. Therefore, option D is correct.

What are the two main types of minerals?
Answer:
The two main types of minerals are macro minerals and trace minerals.
Explanation:
Macro means large in Greek. And your body needs larger amounts of macro minerals. Calcium, phosphorus, magnesium, sodium, potassium, chloride, and sulfur make up the macro mineral group.
A trace of anything indicates that only a small amount of it exists. Even while your body requires trace minerals, it only requires a small amount of each. Iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium are examples of trace minerals.

Explanation:
Explain the general distribution of life in aquatic systems as a function of chemistry, geography, light, depth, salinity, and temperature.
Different types of organisms can exist in a variety of aquatic environments due to the fact that they can vary significantly from place to place and that organisms within each water system will have evolved to adapt to their specific environment.
How does light affect aquatic life?Sunlight plays a vital role in the ocean’s ecosystem. First, sunlight enters the water column, warms it, creates currents, and is then absorbed by phosphorous-rich phytoplanktons. Phytoplanktons use the energy captured by phototrophs (pigments like chlorophylls) to convert water and nutrients into organic matter.
Light availability determines the types of organisms that can live in a particular part of an aquatic environment. The deeper the water depth, the less light it can penetrate until there is no light at all.
The salinity of water affects its density which in turn affects the movement of ocean currents. It may also affect marine life which needs to regulate the intake of salt water. There is a relationship between salinity, temperature, and water density. Therefore, any change in temperature or water density will affect the salinity of the water in the area.
Water chemistry parameters (pH, dissolved organic carbon, and hardness) play a role in metal toxicity by influencing the bioavailability of aquatic species of metals in water.

Cuando una celula se va a dividir, la cromatina se contrae y compacta y forma estructuras como la que se ve al lado. Diga qué nombre reciben estas estructuras y cuantas hay en una célula humana
Answer:
cromosomas
Explanation:
Los cromosomas son moléculas lineales de ADN que contienen parte o todo el material genético de un organismo. El ciclo celular se divide en dos etapas: 1-interfase o etapa de 'no división' y 2-división celular. Durante la interfase, las fibras de cromatina no poseen un grado de condensación suficiente como para hablar de cromosomas. Durante la primera etapa de división celular (es decir, durante la profase), las fibras de cromatina se condensan para formar estructuras compactas conocidas como 'cromosomas' los cuales serán distribuidos entre células hijas. Las células somáticas de los seres humanos son diploides (2n = 46 cromosomas), esto significa que contienen 23 pares de cromosomas homólogos los cuales se alinean durante la metafase de la mitosis en la placa ecuatorial de la célula para ser distribuidos equitativamente entre células hijas durante las fases posteriores del ciclo celular (anafase, telofase y citocinesis). Por otra parte, las células germinales o gametos (espermatozoides masculinos y los óvulos femeninos) son haploides (n = 23 cromosomas) las cuales contienen un sólo set completo de cromosomas.

Garlic mustard has been introduced to the beetles ecosystem. Describe what would happen to the beetles population as a result and explain why.
Answer:
It would collapse
Explanation:
Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plant
In addition, invertebrates and other consumers that rely on these natural plant species for food are harmed by the spread of this invasive "weed". Garlic mustard also produces root exudates that inhibit the growth of important soil fungi and leaf chemicals that kill native butterfly larvae that feed on the plan
Garlic mustard is an invasive plant species that is known to negatively impact native plant populations in ecosystems.
What is invasive plant?An invasive plant is a non-native plant species that is introduced to an ecosystem and has the ability to spread and negatively impact native plant and animal populations.
Garlic mustard is known to release chemicals that inhibit the growth of other plant species, including some that the beetles may rely on for food.
This could lead to a reduction in food availability for the beetles, which may cause a decline in their population.
Additionally, if the beetles are not adapted to feeding on garlic mustard, they may not be able to digest or utilize the plant efficiently, leading to further declines in population.
Thus, the impact of garlic mustard on the beetle population will depend on the specific beetle species and the extent to which they rely on native plant species for food.

Proteins are important food nutrients. A technician working at a food company is interested in the nutritional content of seeds/nuts. She runs a PAGE with samples from two different seed extracts. She runs multiple lanes of the staples. The gel is stained with Coomassie Blue. Seed extract No. 1 has three faint bands at 25, 30, and 35 kDa. Extract No. 2 has two bands at 25 and 35 kDa, and the bands are very dark. What might she conclude from her results about the nutritional value of the seed extracts
Answer: Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.
Explanation:
Proteins are molecules found in the cells of all living organisms. A protein is composed of monomers called amino acids linked together by peptide bonds. To analyze proteins, a technique called SDS-PAGE (sodium dodecyl sulfate polyacrylamide gel electrophoresis) is used. This technique is used to separate proteins according to their electrophoretic mobility, depending on polypeptide chain length, molecular mass, post-translational modifications and other factors. SDS (sodium dodecylsulfate) is an anionic surfactant compound that breaks non-covalent bonds in proteins, denatures them causing these protein molecules to lose their native conformation and provides the polypeptide with a negative charge that is proportional to the chain length (the number of amino acids) and, therefore, to the molecular mass of the protein. The electrostatic repulsion created by the binding of SDS to the protein is one of the causes of the protein losing its native conformation, thus eliminating the differences in conformation of the different proteins to be separated in the gel.
An electric current is applied to the gel where the proteins are seeded, causing the negatively charged proteins to migrate through the gel in the direction of the anode (positively charged region). Short proteins will move more easily and faster through the pores of the gel, while larger proteins will find it more difficult to do so. After a certain time, the proteins will have migrated according to their size (measured in kDa or kiloDaltons). After electrophoresis, the gel should be stained with Coomassie blue or silver stain, allowing visualization of the separated proteins. After staining, the different proteins will appear as distinct bands on the gel. In addition, the higher the amount of a protein, the more intense the color of its band will be.
Extract No. 1 shows three bands: 25, 30 and 35 kDa. This means that it has three different proteins, each with a different molecular weight. Extract number 2 shows two bands: 25 and 35 kDa. It means that this sample has only 2 proteins. And being bands of higher intensity, we can say that there is more of each protein.
Sample 1 then, has more variety of proteins but less quantity of each one, while sample 2 has less variety but more quantity of the two proteins present.

In the presence of lidocaine, the action potential was NOT affected at R1 because _______. In the presence of lidocaine, the action potential was NOT affected at R1 because _______. lidocaine doesn't have an effect on the generation of action potentials lidocaine was applied upstream of R1 lidocaine was applied downstream of R1 there are no voltage-gated sodium channels to be affected
Answer:
In the presence of lidocaine, the action potential was NOT affected at R1 because lidocaine was applied downstream of R1
Explanation:
Lidocaine is an anesthetic that has the power to neutralize neuromal membranes. This anesthetic power allows the ionic fluxes capable of stimulating impulses to be diffused and this allows a dormancy to be achieved. However, when lidocaine is applied downstream to a molecule or structure, the action potential of that structure or molecule is not affected and it may continue to receive impulses.

A gardener crosses tall true–breeding pea plants with short true–breeding ones. Tall plants are dominant to short ones. He collects the seeds to grow F1 plants and then allows them to self–pollinate to form an F2 generation. Which of the following describes the traits of the offspring correctly?
A.
Three–fourths of the F1 and one–half of the F2 plants will be tall.
B.
All of the F1 and three–fourths of the F2 plants will be tall.
C.
Three–fourths of the F1 and all of the F2 plants will be tall.
Answer:
Explanation:
Let T = tall allele (dominant), t = short allele
True breeds are homo-zygous.
So the gardener is crossing TT with tt, with the resulting genotype of F1 all equal to Tt, i.e. all Tall hetero-zygous.
When the F1 pea plants are allowed to self-polinate, F2 results in Tt crossing with Tt, with the genotypes TT, Tt, tT and tt, and phenotypes 75% tall and 25% short, tall being dominant.
