Which statements fail to meet the requirements for scientific claim ?
___________________________________________________________
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.

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.What are the reactants of photosynthesis?

Question 2
Membrane Transport is the movement of substances across the Plasma Membrane. Which of the following types requires energy
Explanation:
active transport is the movement of substances across the membrane using energy from adenosine triphosphate (ATP)
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.
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
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.

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?
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.
5 differences between aerobic and anaerobic respiration
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
What kind of effect can a chromosomal change can have on an organism?
O positive, negative, or no effect
O positive or no effect
O negative effect
O positive or negative effect
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:basicallly what a hypothesis is something you belive in and your trying to prove it. It deifines the relationship between two varaiables.
Explanation:
Answer:
The role of a hypothesis is to give us an idea of what might happen, and if it is right then great, and if it is not then that's fine too because that means it gave us a chance to learn from it and therefore improve our understanding.

2. What are genes, and how are they related to alleles and chromosomes? Start with the definitions of genes and alleles. (2 points)
Answer:
Genes are portions of DNA that contains information to encode proteins
Alleles are different forms of one gene
Chromosomes are closed circular DNA molecules that contain the genetic material of an organism
Explanation:
Genes can be defined as regions of DNA which are transcribed to produce messenger RNAs (mRNAs) by a process known as transcription. Subsequently, these mRNAs are translated into proteins. In diploid organisms, each gene contains two different forms called alleles. A chromosome is a long DNA molecule that contains part or even the entire genetic material of an organism. In diploid organisms, one chromosome contains one allele (inherited from one parent), while its homologous chromosome pair contains another allele of the same gene (inherited from the other parent).

What's the relationship between photosynthesis, chlorophyll, thylakoids, and chloroplasts?
Answer:
The structural unit of photosynthesis is the chloroplast. Prokaryotic and eukaryotic photosynthetic organisms possess flattened sacs or vesicles called thylakoids, which contain photosynthetic pigments. Chlorophyll molecules are attached to specific proteins embedded within membranes, along with carotenoids and other components necessary for photosynthesis.
Explanation:
Chloroplasts are typical and exclusive organelles of plant cells that possess chlorophyll. Because of them, plants are capable of carrying out the photosynthesis process, a process that transforms light energy into chemical energy contained in ATP molecules. The inside is filled with a gel called a stroma. It presents a DNA independent of the nucleus and plastoribosomes. Immersed in the stroma, there are flattened sacs called thylakoids or lamellae, the interior of which is called lumen. Thylakoids can spread throughout the stroma or stack in bundles called grana. In the membrane of grana or thylakoids are located the enzymatic systems that capture the energy of the sun and carry out the transport of electrons to form ATP.
Difference between seedling and germination
Answer:
Explanation:
A seedling is a young plant grown from a seed in the nursery for the purpose of transplanting, while germination is the process of beginning growth from a seed or spore. In germination plants and fungal species, seeds sprouts to produce a seedling and the formation of spores. The stages of germination include, increase water imbibition into the seed, activation of metabolic activities, and protrusion of the radicle.
why is rare to have permanent taste loss ?
Answer:
The answer to this question is given below in this explanation section.
Explanation:
"permanent taste loss"
In many cases the cause is temporary,Such as an infection that inflame the nasal packages.Such as chemical exposure,Alzheimer,s disease and aging, may cause a permanent loss of taste.A lost sense of taste may refer a partial or total loss of taste.People may also use this phrase to describe and overpowering and typically unpleasant taste.
Many medical issue may lead to a loss of taste.Some of these issues are harmless,while other may require a doctor to diagnose them.The type of treatment will depend on the cause.The most common taste disorder is phantom taste perception. A person with this disorder will have strong,lingering taste is their mouth,even when it is empty.
The taste is often unpleasant and may overpower the taste of other foods while they eat.The taste may also occur alongside a president burning sensation in the mouth.
