At which type of boundary do rocks react to tectonic stress and pull away leading to the formation of new crust?
Answer:
Divergent boundary.
Explanation:

What is the material that allows plants to capture energy from the sun? How many different types of this material are there? (site 1)
Answer: The molecules of chlorophyll contained in the chloroplasts absorb energy in the form of light from the sun. This is the process called Photosynthesis, by which plants convert energy from the sun. It is the process that allows plants to create organic molecules that they use as fuel.
Explanation:
During the process of photosynthesis, plants capture light energy and use it to convert water, carbon dioxide, and minerals into oxygen (released into the air) and glucose (stored in the plant and used as food). The photosynthesis process occurs in all plants and algae, as well as in some bacteria species.

Name a storage protein in our bodies.
Explain the function of this storage protein in our bodies.
Where is this storage protein found?
please help
Answer:
Storage proteins serve as biological reserves of metal ions and amino acids, used by organisms. They are found in plant seeds, egg whites, and milk. Ferritin is an example of a storage protein that stores iron. Iron is a component of heme, which is contained in the transport protein, hemoglobin and in cytochromes.

Why can’t food chains go on forever?
Answer:
Because at some point in that food chain, the energy consumption has it's limit, and the predator will not have anything to hunt it. There is a limited amount of energy in a food chain that can go around, and once you reach the predator, that energy doesn't quite run out but it hits that limit where the chain has to repeat itself.

A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below. G-G-A-C-T-T-C-T-T Normal hemoglobin G-G-A-C-A-T-C-T-T Sickle-cell anemia Based on the DNA sequences, sickle-cell anemia is caused by A. a sex-linked trait. B. a dominant nucleotide. C. a mutation in the genetic code. D. an incomplete separation of chromosomes.
Answer:
C. a mutation in the genetic code.
Explanation:
A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.
From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.

What is the short definition of a plant cell?Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Where can you find plant cells?Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals.

what is the difference between cell structure and cell function?
Answer:
These cells have a membrane-bound nucleus that houses their DNA and contain extensive internal organelles (“little organs”) that perform specific functions. ... Differences occur in size, shape, and presence and number of various organelles and other structures. Each cell's structure correlates with its specific function.
Explanation:
Answer:
A cell can be defined as the smallest unit of life and an example include muscle cells. An aggregation of cells form tissues.
The major difference between a cell structure and cell function is in their functions and physical properties.
Cell structure: This talks about how the cells look like when viewed. A call contains components such as the nucleus, cytoplasm, cell membrane etc and each has their various functions to ensure the organisms/animals are able to perform various life activities.Cell function: This on the other hand refers to the various functions which a cell is able to perform and this is dependent on the component in question such as the nucleus which controls cell activities and cytoplasm which provides support and helps to house other organelles.

how does an organism reproduce by budding
Help please ! Thanks
Answer:
75%
Explanation:
The allele for purple flowers (capital P) is dominant.
The allele for white flowers (lowercase p) is recessive.
If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.
The Punnett Square shows:
PP, Pp, Pp, and pp
• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.
• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.
3/4 or 75% of the offspring will have purple flowers.
[tex]\huge\boxed{Option A}[/tex]
_____________________________________ PEA PLANT:Pea plant has purple color flowers dominant over white color flowers.
Purple flower dominant allele is P
White Flower recessive allele is p
We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition
_________________________________________________________
CONDITIONS:Hom.ozygous Dominant Alleles: PP (Purple Flower)
Heter.ozygous Dominant Alleles: Pp Purple Flower)
Hom.ozygous Recessive Alleles: pp (White Flower)
____________________________________ CROSS:Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,
The P1 is Pp
The P2 is Pp
When we cross them,
It has 4 offsprings,
PP Hom.ozygous Purple flower
Pp Heterozygous Purple flower
Pp Heterozygous Purple flower
pp Hom.ozygous white flower
Thus the answer is 75% as there are phynotypically 3 purple flowers present
