It is theorized that the continents on Earth were once joined together,
forming a supercontinent called Pangaea. How long ago did Pangaea
exist? How were the continents of Africa and South America arranged in
relation to each other? Describe one piece of evidence to support their
relationship. Write your response in complete sentences
Answers
Answer:
Pangea existed many millions of years ago in many opinions, but it started back in the late Paleozoic Era until the very late Triassic. Pangea first began to be torn apart when a three-pronged fissure grew between Africa, South America, and North America. Scientists have found fossils of similar types of plants and animals in rocks of similar age. These rocks were on the shores of different continents. This suggests that the continents were once joined. For example, fossils of Mesosaurus, a freshwater reptile, have been found both in Brazil and western Africa.
Explanation:
Answer:
Pangaea is believed to have existed around 335 million years ago during the late Paleozoic and early Mesozoic eras.
During this time, the continents of Africa and South America were joined together as part of the supercontinent Pangaea. They were located in the southern hemisphere, with Africa to the east and South America to the west.
One piece of evidence to support their relationship is the similarity of plant and animal fossils found on both continents. Fossils of the ancient reptile Mesosaurus have been found in both Africa and South America, indicating that the two land masses were once connected. The distribution of fossils of other plant and animal species also suggests that Africa and South America were once part of the same landmass.
The theory of Pangaea and continental drift was first proposed by Alfred Wegener in the early 20th century, and it has since been supported by a range of geological and paleontological evidence. The movement of the continents has had a profound impact on the evolution of life on Earth, as it has created new habitats and allowed for the evolution of new species in isolation.
What best describes ribosomes?
Answers
Ribosomes are cellular structures that synthesize proteins from amino acids. They are composed of ribosomal RNA and proteins and are found in both prokaryotic and eukaryotic cells.
Ribosomes are essential for gene expression and cell growth. They can be free in the cytoplasm or bound to the endoplasmic reticulum or the nuclear envelope.
An example of a ribosome function is the translation of a messenger RNA (mRNA) sequence into a polypeptide chain. The ribosome reads the mRNA codons and matchesthem with the corresponding transfer RNA (tRNA) anticodons that carry the amino acids. The ribosome then forms a peptide bond between the amino acids and releases the tRNA. This process continues until the ribosome reaches a stop codon on the mRNA and terminates the protein synthesis.
Answer:
A ribosome is a intercellular structure made of RNA and protein

explain how matter cycles through non living and living things in a aquaponics system. Give at least one example.
Answers
The commercial industry of aquaponics is rapidly growing; however, these systems can easily be established in backyards or bright rooms, by anyone. Home-based aquaponic systems can vary greatly in size. Outdoor systems may utilize a small area of a backyard, existing space around a pond, or even an entire backyard. Indoor systems may be set-up with plastic tubs near bright windows to minimize the usage of plant lights, or even added on to an indoor aquarium. Both outdoor and indoor aquaponic systems can provide fresh, local food for a single person, a family, or even multiple households. The amount of food and fish produced only depend on the size of the working system.
There are many benefits to choosing aquaponic systems over traditional growing

methods. The relationships between the fish, bacteria, and plants keep the water quality high while allowing the plants to gain biomass. Water use is greatly reduced compared to traditional gardening by circulating it through the system, rather than allowing it to percolate down to the ground water or run-off in the surface water. Thus, there are no concerns regarding soil erosion and run-off with aquaponics. Evaporation from the substrate (soil in normal gardening) is also minimized by the circulating water and nutrient delivery system. Only water loss through leaf transpiration and harvesting is comparable to what is seen in soil-based plant production. Since the fish waste provides nutrients to the plants, the use of chemical fertilizers and nutrients is also greatly reduced. Pesticide and herbicide use is eliminated to sustain the fish. If an additional greenhouse is used to cover the system, fresh produce and fish can be grown nearly year-round in most climates. The water in a well functioning aquaponic system never needs to be replaced, unlike in hydroponic systems where nutrient imbalances occur over time. The chemicals that build up in hydroponics systems can also pollute waterways if not disposed of properly. Aquaponics systems also avoid the toxicity problem of built up nitrites seen in aquaculture systems. The nitrites are converted into nitrates by bacterial populations in established aquaponic systems, which the plants take up and utilized as their nutrient source. Aquaponics systems rely on natural processes between fish, bacteria, and plants, to provide many benefits compared to other methods of growing food.

Answers
Answer: E
Explanation:
Experiment Design:
Independent Variable: Intensity of light (Low, Medium, High)
Dependent Variable: Rate of photosynthesis (measured by oxygen production or CO2 consumption)
Control: Same kind of plant, constant temperature, constant CO2 concentration, constant water availability, and constant duration of light exposure.
Materials:
Three identical potted plants (of the same species)
Light source(s) with adjustable intensity
Light meter (lux meter) to measure light intensity
CO2 gas sensor or oxygen gas sensor
Timer or stopwatch
Water supply
Thermometer
Data recording sheets
Procedure:
Set up the three identical potted plants in a controlled environment with the same temperature and CO2 concentration.
Ensure that all plants receive the same amount of water.
Place the light source(s) at an equal distance from the plants.
Measure and record the initial light intensity using the lux meter.
Adjust the light intensity to low for the first plant, medium for the second plant, and high for the third plant.
Start the timer and expose the plants to light for a specified duration (e.g., 1 hour).
During the exposure period, measure and record the temperature, CO2 concentration (if possible), and light intensity at regular intervals.
After the exposure period, use the CO2 gas sensor or oxygen gas sensor to measure the change in CO2 concentration or oxygen production, respectively, in the surrounding air.
Record the data obtained from the sensors and calculate the rate of photosynthesis for each plant.
Repeat the experiment multiple times to ensure reliability and average the results.
Analyze the data collected and compare the rates of photosynthesis among the three different light intensities.
Draw conclusions based on the analysis and determine whether the hypothesis is supported or rejected.
By following this experimental design, you can test the hypothesis and determine the effect of light intensity on the rate of photosynthesis in plants. Remember to conduct the experiment in a controlled environment and gather sufficient data for accurate analysis.

B. The species have similar bone structure.
C. The species live in the same environment.
D. The species both obtain oxygen from the air.
Answers
Answer:
I think its B) The species have a similar bone structure
Explanation:
Answer:
The correct answer to this question is B. The species have similar bone structure.
Explanation:
In biology, homology is the similar structure, physiology, or development of various species of organisms based on their ancestry from the same evolutionary ancestor. An analogy, on the other hand, is a functional similarity of structure that is based not on shared evolutionary origins but rather on simple similarity of use. Homology is contrasted with analogy.
As a result, mammals with vastly different forelimbs, such as humans, bats, and deer, are homologous, Adaptive changes to the forelimb structure of their common early mammalian ancestors are represented by the nearly identical construction and number of bones in these diverse limbs. Similar to structures, then again, can be addressed by the wings of birds and of bugs, Both kinds of organisms use the structures for flight, but they didn't have a common ancestor at the start of their evolutionary development. Sir Richard Owen, a British biologist who lived in the 19th century, was the first to precisely define homology and analogy.
Serially homologous organisms are those whose structures are fundamentally similar to one another but have been altered to carry out distinct functions. The flipper of a whale and the wing of a bat are two examples of this. Both evolved from the forelimbs of their earliest mammalian ancestors, but they have evolved in distinct ways to perform the vastly distinct functions of flying and swimming, respectively. Some of the time it is hazy whether similitudes in structure in various creatures are similar to or homologous.

When an offspring receives one green allele (G) and one red allele (R), the result id a green leaf with red veins
Answers
Answer:
GR
Explanation:
the genotypes of the parents are homozygous dominant GG and RR so when they fertilise they give all GR offsprings
The genotype of the plant is GR. This is because the offspring received green allele (G) as well as red allele (R), and both results showed up as the plant is green with red veins.
When something gives up alleles to its offspring, the parents originally have alleles like Aa and Bb. When offspring is created, you can use the Punnett square to guess which alleles will be passed on. In the plant’s case, G and R were passed on.
