What are the resources/factors that all organisms compete for in their environment?
How do adaptations allow an organism to compete "better" for those resources/factors?
Answers
Answer:
Organisms with the best adaptations are the ones who are can compete for the best. They are the ones who survive. Predators, animals that hunt other animals, must compete to find prey. Prey, animals that get eaten by predators, must compete to stay away from predators and to find their own food.

why does moving pollen from one pollen to another help the plants
Answers
Answer:
Flowers have male parts called stamens that produce a sticky powder called pollen. When pollen from a plant's stamen is transferred to a different plant's stigma, it is called cross-pollination. Cross-pollination produces stronger plants. The plants must be of the same species.

5 differences between aerobic and anaerobic respiration
Answers
Aerobic Respiration
*Oxygen is present when this form of respiration takes places
*In this form of Respiration gases are exchanged
*it can be easily found in the cytoplasm and mitochondria
*glucose breaks down into carbon dioxide and water
*all higher organisms such as mammals have this type of respiration.
Anaerobic Respiration
*Oxygen absent
*Gases aren't exchanged
*found only in the cytoplasm
*Glucose breaks down into ethyl alcohol, carbon dioxide and energy
*bacteria and yeast use this type

Before the 1960s, most ecologists thought that the number of producers in an ecosystem was the only variable that limits the number of herbivores. The idea was that every level was regulated by the amount of food from the trophic level below it.
Answers
The complete question is as follows:
1. How did the green world hypothesis differ from this “bottom-up” view?
2. Imagine a simple food chain: Grass -> Grasshoppers -> Mice. If snakes that eat mice are added to the ecosystem, how would you redraw the food chain to represent this change?
3. After the snakes are added, would you expect the amount of grass to increase or decrease? Explain your reasoning.
Answer:
1. The green world hypothesis states that plants or producers are consumed in less quantity by herbivores due to predators and other conditions which is different from the hypothesis as it says the number of the herbivores are regulated by the organism above them in the food web instead of below.
2. before adding snake: Grass →Grasshoppers →Mice ( arrow towards predator)
After adding the sakes: Grass →Grasshoppers →Mice→Snakes. (as snakes eat mice so they will be added after mice)
3. The grasses will decrease as there would be fewer mice due to snakes and the number of grasshoppers will be high which leads to the decrease in the amount of grass.
1.Pine pollen grains often have air sacs.*
True
False
2.Division 1 of meiosis is called "reduction division." *
True
False
3.Fruits develop from the stamens.
True
False
Answers
Answer:
1 true
Air-filled sacs in the pollen grains of pine trees allow pollen to travel farther through the air. ... Each pollen grain is attached to two or three air-filled sacs, or sacci, which develop from the outer layer of the pollen
2 true
process of meiosis involves two divisions of the genetic material. The first division is called the reduction division – or meiosis I
3 false
When a grain of pollen reaches the stigma, it creates a pollen tube for the sperm to journey down the style and fertilize the ovule; fertilized ovules become seeds. Fertilization is the death of the flower, as the petals drop or wither at this point and the ovary starts to enlarge and ripen into what we know as fruit.

Which statements fail to meet the requirements for scientific claim ?
Answers
___________________________________________________________
Answer:
The correct answer would be the first and third statements.
___________________________________________________________
___________________________________________________________
Explanation:
A scientific claim is defined as a statement which is a conclusion obtained from numerous experiments and observations.The scientific claim usually remains the same in the provided conditions. In the first statement, Copernicus's model stating that the planets revolve in the circular orbits around the sun was not accepted and thus, it is not a scientific claim. Similarly, Newton's laws of motion are uniform and work properly in the environment. Thus, it also does not form a scientific claim.

O positive or no effect
O negative effect
O positive or negative effect
Answers
Answer: Positive or negative effects.
Explanation: Chromosomal changes is called mutation. Mutation is change or alterations in genetic constituents or chromosomes of an organisms. Not all chromosomal changes are negative or causes genetic disorder bit some have positive effects too. The negative effect causes some genetic disorders but the positive don't have negative impact on health but only the chromosomal sequence might be alter , it functions is still intact.

Answer:
According to the diagram, what is occurring in step 7 is cytokinesis, with the separation of two daughter cells, following cell division.
Explanation:
Cytokinesis is a process that occurs at the end of mitosis or meiosis, being the final step of cell division. This mechanism allows the separation of the two daughter cells, with equal distribution of cytoplasm and formation of cell membrane, differentiating into two independent cells.
In the diagram it can be observed (step 7) that after the division process —in yellow— two arrows pointing to two cells are evident, which implies the process of cytokinesis.
Prior to the cytokinesis process, karyokinesis occurs, which is the separation of nuclei and formation of the nuclear membrane.
In animal cells, karyocinesis occurs by the effect of a ring of actin and myosin that helps to force the separation. In the plant cell, the fragmoplast is formed, a septum that induces the separation of the daughter cells.
The other options are not correct because:
Cell growth occurs in G1 phase.Cell preparation occurs in interphase.DNA replication occurs in S phase.Mitosis is represented in yellow, and involves 4 phases.Which of the following best explains why the atomic theory changed over the past 200

Answer: I don't think so
