Answer:

A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Answer:

1. C.) Their cell walls contain chitin

2. C.) Chloroplast

The correct order is:

1) BBP and U2AF bind to the A in the branch-point site in the intron, while the U1 snRNP binds the 5' splice site > 2) the U2 snRNP binds the branch-point site and the U4/U6 and U5 snRNPs bind to the 5' splice site > a conserved adenine in the branch-point site attacks the 5' splice site, cutting the RNA at the 5' splice site > the 3' end of the intron binds the branch-point adenine, forming a lariat > the 5' end of the second exon interacts with the 3' splice site forming a new bond in the sugar-phosphate backbone > the lariat is released and degraded.

The non-coding introns of the pre-mRNA are eliminated during the process of RNA splicing, and the coding exons are then combined to create the final mRNA molecule. Five small nuclear ribonucleoproteins (snRNPs) and countless other proteins make up the large ribonucleoprotein complex known as the spliceosome, which is responsible for carrying out this process.

A branch-point adenine within the intron is connected to the 5' end of the intron during RNA splicing to create a lariat structure. After that, the intron's 3' end is cut, and a phosphodiester bond is used to connect the two exons. The spliceosome's internal catalytic processes and interactions with RNA-proteins drive this process. The cytoplasm is where the protein-making process begins when the spliced mRNA is transferred there.

Explanation:

Fox went on to create microspheres that he said closely resembled bacterial cells and concluded that they could be similar to the earliest forms of life or protocells. Hope this helped :)

A number of genetic networks are linked to the growth and withering of plants, flowers, and fruits, and the phytohormone ethylene is important.

Many plants have evolved flowers as a means of producing seeds for the germination of new plants. Some flowering plants attract insects with their vibrant petals and sugary liquid known as nectar. Visiting insects aid in spreading honey among flowers so that seeds can develop.

Sexual reproduction results in variable offspring, which gives populations diversity and variance. It is crucial for plants because it gives variation to the offspring, which aids in improved survival, enables it to become distinctive within the species, and helps it get rid of undesirable genes.

Several hominins, especially the well-represented Australopithecus afarensis, had lower limb morphology indicating very efficient bipedal locomotion.

Bipedal locomotion refers to the ability to walk upright on two legs. Australopithecus afarensis, an extinct hominin species that lived between 3.9 and 2.9 million years ago, is known for its bipedal adaptations. Fossil remains of Australopithecus afarensis, including the famous specimen "Lucy," show skeletal features such as a forwardly positioned foramen magnum (indicating an upright head position) and a pelvis and lower limb bones consistent with bipedal walking.

These adaptations suggest that Australopithecus afarensis predominantly moved around on two legs, a key characteristic that distinguishes hominins (including humans) from other primates that primarily use quadrupedal locomotion.

We know that cellular respiration involves the production of ATP.

Cellular respiration is the process by which cells convert the energy stored in organic molecules (such as glucose) into a form that can be used by the cell, known as ATP (adenosine triphosphate).

The process of cellular respiration involves several stages, including glycolysis, the citric acid cycle, and the electron transport chain, which occur in the cytoplasm and mitochondria of cells. Cellular respiration is a vital process for all living organisms as it provides the energy required for cellular processes such as growth, reproduction, and response to stimuli.

One example of a contagious disease is the flu, also known as influenza.

The flu is caused by a virus known as the influenza virus, which belongs to the Orthomyxoviridae family.

Symptoms of the flu include fever, chills, cough, sore throat, runny or stuffy nose, muscle or body aches, fatigue, and sometimes vomiting or diarrhea. Symptoms typically appear within 1-4 days after infection and can last up to a week.

The flu is primarily spread through respiratory droplets when an infected person talks, coughs, or sneezes. The virus can also be spread by touching a surface or object that has the virus on it and then touching your mouth, nose, or eyes.

There is a cure for the flu. The primary treatment for the flu is antiviral medication, which can shorten the duration of the illness and prevent severe complications. Antiviral drugs can be taken within the first 48 hours of symptoms appearing to be most effective. Vaccination is the best way to prevent the flu. Your doctor can recommend the best treatment course based on your situation.

Polycomb group proteins are a group of gene-regulating proteins that have been conserved in evolution and play important roles in development and cell differentiation.

They are essential for the maintenance of gene repression. The role of Polycomb group proteins in maintaining gene repression is as follows:

Polycomb group proteins control the transcriptional activity of genes by regulating chromatin structure, which is crucial for gene expression. They do this by modifying the histones that make up the nucleosomes in chromatin, which in turn affects the accessibility of the DNA to the transcriptional machinery.

In particular, the Polycomb group proteins catalyze the methylation of histone H3 on lysine 27, which leads to the recruitment of other repressive proteins that maintain the chromatin in a compact, inactive state.In addition, Polycomb group proteins also function in higher-order chromatin organization. They help to organize chromatin into higher-order structures, such as loops and domains, which can have important effects on gene expression.

This is achieved through the recruitment of other proteins, such as insulator proteins, which help to establish boundaries between different chromatin domains. In summary, Polycomb group proteins are critical for the maintenance of gene repression by regulating chromatin structure and higher-order chromatin organization.

The microfossils that are useful for paleotemperature determination using the oxygen isotope ratios of their shells are foraminifera.

Foraminifera are tiny marine animals that have been living for millions of years. Their shells are made up of calcium carbonate and are well-preserved in sediments. The shells of these microorganisms are widely used in paleoceanography to determine past climatic conditions. Paleoceanography is the study of the history of the oceans in the geological past using sediments and fossils. It helps us to understand how the oceans and climate have changed over time.

Paleotemperature is the measure of the temperature that existed in past geological ages. The temperature is determined by various means, including studying the growth rings of trees, ice cores, and microfossils, and others. Microfossils are microscopic fossils that are found in rocks and sediments that help in reconstructing past environmental and climatic conditions.

Oxygen isotope ratio is the measure of the relative abundance of oxygen isotopes 18O and 16O in a sample. The ratio of the two isotopes changes as a result of temperature changes. The ratio is used to reconstruct past temperature changes.

Answer:

Gravity is the force that gives weight to objects and causes them to fall to the ground when dropped. Two major factors, mass and distance, affect the strength of gravitational force on an object. You witness the first factor in everyday life - more massive objects are heavier.

Explanation:

"Acceleration due to gravity" typically refers to the increase in speed of a falling object due to the gravitational pull of the Earth. If jump out of a plane, your speed increases towards the Earth (or the center of the Earth really) due to the acceleration of gravity. If you throw a ball up in the air, it slows down and falls due to the acceleration of gravity. I guess it's specified because the force of gravity is causing the acceleration in these instances; as opposed to some other outside force.

Step 1.

Write down the experiment data.

- tube containing water;

- alodea (photosynthetic organism);

- 10 g of sodium bicarbonate;

- light source.

Step 2.

Why bubbles are formed on the leaves of the alodea?

The experiment have all the condictions for photosynthesis, since it provides: water (that is in the tube), CO2 (because of the dissolved sodium bicarbonate), light (because of the string light source). Therefore the most ogical explanation for Alice experiment results is: the bubbles formed as the elodea plant releases oxygen from the elodea leaves, that because with all the elements in the experiment the plant can do a normal photosynthetic process that way realing oxygen in the tube and forming bubbles of "air".
