Answer: Homologous Structures
Explanation:
a yellow pea plant is dominant to green determine the phenotype (yy)
Having extra fingers (polydactyly) is a dominant trait. Having just 10 fingers is a recessive trait. How can you explain that almost (if not everyone) you know has the "normal" number of fingers? Look at the list of dominant vs recessive genes and give another example of a recessive gene being more common than a dominant one and explain why you think that dominance or recessiveness is not related to how often a trait occurs in a population
Answer:
Explanation:
Polydactyly is a mutation, it is a sudden change that can be heritable that occurs.
Because mutation does not always occur the chances of having large number of people having the traits in a dominant form is low, hence more people will have normal finger.
Dominance is not the number of time a traits occur, it is the ability of a allele to be expressed over another. The expressed allele i.e that is seen in the phenotype of such individual is the dominant allele while recessive allele are the one whose effect are mask.
Having a round eye is an example of a recessive traits that people posses but are expressed in some individual.

What are the raw materials for photosynthesis
Answer:
Food and water
Explanation:
Its pret east
All organisms need energy from food. Which best describes
the process of how plants and animals get usable energy
from food?
Answer:
Plants build carbohydrates using light energy from the sun (during the process of photosynthesis), while animals eat plants or other animals to obtain carbohydrates.
Explanation:
Animals eat plants or other animals to obtain carbohydrates, whereas plants create them using the sun's light energy and the process is called photosynthesis.
What is photosynthesis?Photosynthesis is defined as the process through which plants convert carbon dioxide, water, and sunshine into oxygen and sugar for energy.
It can also be defined as a method used by plants and other living things to change light energy into chemical energy that can then be released through cellular respiration to power the organism's activities.
The process of photosynthesis is unique to plants since only those with the food-making chlorophyll pigment can carry it out. The necessary elements are sunlight, water, and oxygen, where two processes take place: one that depends on light, the other that doesn't.
Thus, animals eat plants or other animals to obtain carbohydrates, whereas plants create them using the sun's light energy and the process is called photosynthesis.

Answer:
brainliest plzzzzzzzzzzzzzzzzzz
Explanation:
1.Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells
2. Gene therapy is designed to introduce genetic material into cells to compensate for abnormal genes or to make a beneficial protein. If a mutated gene causes a necessary protein to be faulty or missing, gene therapy may be able to introduce a normal copy of the gene to restore the function of the protein.
3.Gene therapy does have risks and limitations. The viruses and other agents used to deliver the "good" genes can affect more than the cells for which they're intended. If a gene is added to DNA, it could be put in the wrong place, which could potentially cause cancer or other damage.
4.Clinical trials of gene therapy in people have shown some success in treating certain diseases, such as: Severe combined immune deficiency. Hemophilia. Blindness caused by retinitis pigmentosa.
5. Few Examples Are:
Engineered Natural Killer Cells against Hodgkin's Lymphoma. Pectic Acid-based Corning Dissolvable Microcarriers for Cell Therapies. Development of Cell Expansion Systems for Gene-edited Blood and Immune Cells. Microsoft's AI Tool for Fine Tuning CRISPR.how does time affect the physical weathering of a rock?
A- rock weathers the most when first exposed, then more slowly
B- the longer the rock has been exposed, the more it has weathered
C- over time, the rock will become flat, slowing the rate of physical weathering
D- time does not affect physical weathering, only chemical weathering
Answer:
D
Explanation:
Time can't do much to a rock, but chemical weathering is more effective
The time affect the physical weathering of a rock as time does not affect physical weathering, only chemical weathering and time can't do much to a rock, but chemical weathering is more effective. Thus, option D is correct.
What is the sedimentary rocks?Sedimentary rocks are near the surface so the only one that works for that is sedimentary rocks are formed with water too, it weathers away at the rocks to form little sediments and metamorphic rocks are in the earths interior and sedimentary are at the exterior, metamorphic rocks are formed through extreme heat and pressure meaning its near the earths interior.
Igneous rocks has been called the magmatic, are all rocks that are formed by the solidification of magma. However, igneous rocks are classified into two groups. First are the plutonic or intrusive igneous rocks that are the result of the solidification of magma within the lithosphere. Secondly, there are the volcanic or extrusive igneous rocks that are the result of the cooling of magma that occurs at the surface or a shallow depth.
Therefore, The time affect the physical weathering of a rock as time does not affect physical weathering, only chemical weathering and time can't do much to a rock, but chemical weathering is more effective. Thus, option D is correct.

Draw a portion of a plasma membrane of a cell and label the cytoplasmic and extracellular surface. Place the following four proteins in the membrane: a) peripheral membrane protein (cytoplasmic exposure), b) integral protein (transmembrane exposure), c) integral protein (extracellular exposure) and d) peripheral protein (extracellular exposure)
Answer:
You will find the draw in the attached files.
Explanation:
Integral proteins: Proteins that are permanently encrusted in the membrane. These molecules might be classified into three groups: transmembrane proteins, those encrusted in one of the monolayers, and those that only join a membrane protein.Transmembrane proteins cross the membrane from side to side. They have three domains in their monoacidic sequences: an extracellular hydrophilic domain, an intracellular hydrophilic domain, and an interior hydrophobic domain. The aminoacidic chain of these molecules might cross the membrane just once or many times, depending on the protein. Transmembrane proteins accomplish many functions, such as substance adhesion, ions interchange, molecules transport, communication, among others.
Proteins encrusted in one of the monolayers do not cross the membrane. Their monoacidic sequences are integrated with only one of the monolayer lipids, hence they have an intramembrane domain and only one extramembrane domain, which might be either cytosolic or extracellular, depending on their position in the membrane.
Peripheral membrane protein: Proteins that are not encrusted in the membrane, but just united to the internal or external membrane surfaces, and they can easily separate from it. Opposite to integral proteins, peripheral ones are not in a permanent association with the membrane. Instead, they are just temporally united to the membrane. This makes them useful for cellular communication. They can be attached to integral proteins and little portions of the lipidic bilayer.Which statement best describes the movement of Earth’s plates?

Why a litter of puppies with the same parents can all look different include words like gamete, zygote, chromosome, gene
Answer:
Because of the recobonation, not all the puppies will receive the same chromosomes from the parents. The genes can/will be transmitted differently and unequally between the puppies. These genes will be carried from the zygotes, the zygotes carry the genes from BOTH parents.
Puppies with the same parents can look different because of recombination.
What is recombination?Recombination is a process by which pieces of DNA are broken and recombined to produce new combinations of alleles.
A Litter of puppies with same parents can all look different because of recombination. At the time of meiosis the number of chromosomes reduced and genetic recombination takes place.
Meiosis is a form of cell division that produces gametes. Meiosis is divided into different phases such as prophase, metaphase, anaphase and telophase. Crossing over takes place at pachytene stage. Cross over results in recombination and exchange of genetic material.
Recombination process creates genetic diversity and leads to variation. Chromosomes contains genes. When male and female cells fuses it leads to formation of zygote.
Therefore, Puppies with the same parents can look different because of recombination.

Which might be considered a limiting factor to the amount fish in a lake *
A)Amount of squirrels in the environment
B)Amount of water in the lake
C)Temperature of the lake
D)Choice 2 and 3
Answer:
D). Choice 2 and 3
Explanation:
Given the options above, the limiting factors are both the "Amount of water in the lake" and the "Temperature of the lake"
This is because the amount of water in the lake can only carry as much of the number of fishes as possible it can contain or sustain. This implies that the higher the water content in the lake the higher the number of fishes it can contain and vice versa.
Also, the temperature of the lake is a limiting factor because the temperature of the lake supports the light penetration to the fishes in the water. Should the temperature increases beyond the highest level the water can support, the fishes will die.
