The percentage germination of mongo seeds is an important measure in evaluating seed quality. It is also used to determine seedling vigor, which is important for successful seedling establishment and growth.
To determine the percentage germination of mongo seeds, one should first prepare the sample. This involves counting out the desired number of seeds and placing them in a container filled with warm water. The water should be changed and the seeds should be agitated periodically for about 12 hours. After 12 hours, the seeds should be drained and placed in a moist paper towel.
Once the seeds have been placed in the moist paper towel, they should be incubated in a warm location for several days. This allows the seeds to begin the germination process. During the incubation period, the paper towel should be monitored and kept moist.
Once the germination process has begun, the percentage germination can be calculated. To do this, the seeds should be counted and the number of seeds that have germinated should be recorded. The percentage of germination can then be calculated by dividing the number of germinated seeds by the total number of seeds, and multiplying the result by 100.
Another important part of the process is determining the quality of germination.

C: Converting radiant energy into chemical energy.
Explanation:
Only plants (producers) in a typical ecostystem can convert radiant energy into chemical energy.
Answer:
Converting Radiant energy into Chemical energy.
Explanation:
There are two main purposes for plants. 1. Providing oxygen 2. serving as producers. As we know, plants take in the sunlight from the sun and make glucose with it. This glucose in its form is chemical energy that benefits both the plants, or the consumers that eat them, or some parts of the plant. It does not talk about oxygen or atmosphere except for nitrogen, which they actually get from the ground. Therefore, Converting Radiant energy into Chemical energy would be the right answer.

A biologist is using a dichotomous key to identify fish.
1. (a) Has a single dorsal fin ® 5
(b) Has a double dorsal fin ® 2
2. (a) One fin is spiny, the other is smooth ® 3
(b) One fin is not spiny or smooth ® 4
5. (a) Has small fin on back near tail ® 6
(b) Has no fin on back near tail ® 7
6. (a) Has barbs near the mouth ® Catfish
(b) Does not have barbs near the mouth ® 10
7. (a) Tail is asymmetrical ® 8
(b) Tail is symmetrical ® 9
10. (a) Scales are small ® Trout
(b) Scales are large ® Whitefish
What is the next step to take to identify a fish that has a single dorsal fin and no fin on the back near the tail?
step 5
step 2
step 7
step 6
Answer:
The next step to take to identify the fish is step 7.
Explanation:
A dichotomous key is relatively simple to interpret. All you need to do is to:
carefully observe your organism, know some technical terms or have a biological dictionary, and follow the descriptions.The dichotomous key is going to lead you to the answer. Each step states two descriptions -a and b-, that are the potential answers. You need to observe your specimen and see which of the descriptions matches the organism. Once you choose the correct description, the key leads you to the next step. In the next step, the procedure is the same. You have to repeat it until you reach the name of your organism.
So, in this example, our organism is a fish, and we know that it has a single dorsal fin and no fin on the back near the tail. So,
1. (a) Has a single dorsal fin ---------------- step 5
(b) Has a double dorsal fin ----------------step 2
We have two options, single dorsal fin or double dorsal fin. Our fish has a single dorsal fin, so the correct option is (a). By choosing (a), the key sends us to step 5. Note: In the hypothetical scenario of having a double dorsal-finned fish, the correct option would be (b), which would lead us to step 2.
5. (a) Has small fin on the back near tail ---------- step 6
(b) Has no fin on the back near tail -------------- step 7
Again, we have two options, with a back fin near the tail, or without. Our fish does not have any back fin near the tail, so we choose option (b). This option leads us to step number 7. Note: In the hypothetical scenario of having a fin in the back near the tail, we should choose option (a), which leads us to step 6. But this is not the case. So we go to step 7.
7. (a) Tail is asymmetrical --------------- step 8
(b) Tail is symmetrical ----------------- step 9
Once in 7, we need to see if our specimen has a symmetrical or asymmetrical tail. Depending on the answer, we go to step 8 or 9. And so on until we get to know the name of the fish.
Answer: The correct answer is step 7

In an area where trees are growing taller, the giraffe population must adapt if it is to survive. Which statement BEST explains how the giraffes would be able to survive and reproduce?
F The genetic material for neck length within the offspring must mutate.
G The trait for longer legs would have to be a response to the change in the environment.
H The genetic material for smaller, shorter hind legs must exist within the giraffe population.
J The trait for longer necks must exist within the population and be inherited by the offspring.
Answer:
J. the trait for longer necks must exist within the population and be inherited by the offspring
Lamarckism was the theory was given by Lamarck and is based on physical changes. Giraffes would be able to survive when the traits of the long necks are inherited. Thus, option J is correct.
What is inheritance?Inheritance is the passing of the genetic material down the generation so that the beneficial traits that are essential for survival are passed from one generation to another.
When the trait essential for the giraffes to survive like long necks and legs are passed from one generation to another through reproductive methods then they will be able to survive.
Therefore, option J. trait for the longer neck must pass or be inherited by offspring.

1. explain how body plan and anatomy enables invertebrate to perform essential functions it needs to survive.
2. explain how body plan and anatomy enables chordate to perform essential functions it needs to survive.
3. explain how body plan and anatomy enables primate to perform essential functions it needs to survive.
Answer:
1)Invertebrates are known as creatures that do not have backbones. Even though these creatures do not have backbones, they have been uniquely designed in order to survive. According to studies, most of these creatures are found in the sea and one of them is the Star Fish or also called as the Sea Star. Starfish's functions and ability to survive is not the same like other animals which make them unique in a different way. The starfish's body is hard and bony for protection purposes and they exist in a variety of colors for camouflage. Their essential functions in order to survive are as follows:
-The Ability to Regenerate: Starfishes have the ability to grow damaged and lost limbs or even their entire body as long as the center part is still present and intact. And this is their way of reproduction as well.
-Having Tube Feet: Its arms are covered with a suction-like tiny cups of tube feet. This unique design of the starfishes enables them to move and secure themselves, especially on rocks and ocean floors.
-Unique Feeding Ability: Sea Stars don't have mouths nor teeth to ingest food. Rather, these creatures have the ability to push open or turn their stomachs out and digest its food. After digestion, their stomachs retract back to their bodies.
-Vascular System: How starfishes survive does not rely on having hearts, brains and blood. Rather, they use the seawater. The seawater serves as the one the circulates inside the sea stars' bodies and this is when nutrients and oxygen are being transported and absorbed.
2)Keep in mind invertebrates are those who have exoskeletons (outside skeleton) or are hydrostatic (no skeleton). This make up 95% of all animals for example an ant or sponge. For a sponge, all it has is tissues that enable it to allow water to flow out the tops.
Chordata are anything with vertebrates so a simple fish could suffice. THEY HAVE 4 SPECIFIC CHARACTERISTICS: 1.Notochord 2.Dorsal, hollow nerve cord 3.Pharyngeal slits 4.Muscual, an.al tail
This is us, we have thumbs, and vertebrates.
3)The bipedalism of primates puts their heads on a higher elevation and this allows them to see predators or prey from afar hence giving them advantage. Opposable thumbs on the hand and feet allow primates to grasp and handle objects effectively hence are able to make use of tools for hunting and etcetera

A preservation biologist conducted an experiment on two islands (A and B) of similar size, climate, species composition, and richness. Originally, a large population of the same invasive species, a brown tree snake, was present on both islands. It had led to the extinction of some native lizards and forest birds. In her experiment, the biologist removed the brown tree snake from island B but not from island A. She then recorded the number of animal species on each island over a period of 24 months. The data collected is shown in the graph below:
Analyze the data above in terms of interspecific relationships and communities. Which statement best explains the difference in species present on each island over the course of the experiment?
The scientist is the ecosystem engineer of island B.
The brown tree snake was a keystone species on island B.
The brown tree snake is a foundation species on island A.
The brown tree snake is the ecosystem engineer on island A.
Boiga irregularis or brown snake is a slender, climbing snake with a vertical pupil and large eyes, providing it better nocturnal vision. The species has no natural predator. When the brown snake is accidentally released into the island, it will result in local extinction of the majority of the island's native lizard and bird species.
It will also result in cascading ecological influences by eradicating native pollinators, resulting in the corresponding reduction of the native plant species.
Hence, the correct answer will be fewer birds and more snakes.
Ecosystemic engineers might affect the ecosystem structure and community dynamics. Option D. The brown tree snake is the ecosystem engineer on island A.
What are ecosystem engineer species?
Ecosystemic engineers are organisms that can modify the environment in which they live, influencing other species by changing biotic and abiotic factors and affecting resources availability.
Usually, the interaction of ecosystemic engineers with other species has a consequence on the ecosystem structure and equilibrium.
Based on this concept, many invasive species are considered ecosystemic engineers.
Invasive species are uncontrollable and provoke significant damage to the structure of native ecosystems, affecting endemic species. They produce ecological imbalances in the trophic chains and the dynamics of communities.
By affecting the structure of native ecosystems, they produce cascade effects in resident biota, altering the composition and habits of species in the region and modifying physical and chemical conditions in the environment.
The statement that best explains the difference in species present on each island over the course of the experiment is that The brown tree snake is the ecosystem engineer on island A. Option D.
As we can see, in the presence of the brown tree snake, many species suffered extinction on island A, probably by both direct and indirect effects of the invasive snake.
Island B, on the other hand, kept plenty of species diversity. This is because the snake was removed from the island. Native species managed to increase their population size and to establish again.

Miss Emily's hometown in Alabama is the town in which William Faulkner's story "A Rose for Emily" is set, while Woodstock is a small community in Bibb County, Alabama. Despite the fact that the two places are distinct, there are a few similarities between them.
First and foremost, both towns are situated in Alabama, which means that they share a geographic location. Both towns are in the Deep South, a region known for its sultry climate, and both are located in rural areas. This implies that the two towns are exposed to comparable weather patterns and experience similar seasons throughout the year.
Second, both towns have a rich history, which is reflected in their architecture and cultural traditions. For example, Miss Emily's hometown has a beautiful but decaying old Southern mansion, which is symbolic of the town's former glory. Similarly, Woodstock, like many other small towns in the region, has numerous old homes and buildings that are over a century old.
