What information is lost if only scientific results are reported and the historical context
is not considered? Is this lost information relevant if the science gets done?||
Answer: Literature review
Explanation:
The literature review is important to cite the previous information about research conducted earlier and taken as a reference for the present study. It may contain the principle, methodology and other information which can be used in the current research. The literature review makes the information of the current research valid and authentic, thus it is considered valid.
body tissues are system of specialized cells that carry out common function. How are proteins and body cells related?
Answer:
Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body's tissues and organs. ... There are 20 different types of amino acids that can be combined to make a protein. Both do most the work.

True-breeding pea plants have either spherical seeds or dented seeds with spherical being the dominant phenotype. A genetic cross between two F1-hybrid pea plants for spherical seeds will yield what percent of plants with a heterozygous genotype in the F2 generation?
A. 0%
B. 25%
C. 50%
D. 75%
A genetic cross between two F1-hybrid pea plants for spherical seeds will yield 50% of plants with a heterozygous genotype in the F2 generation. Thus, the correct option for this question is C.
What is a Genotype?A genotype may be defined as the ultimate combination of alleles of those genes that are subsequently selected for specific study in order to reveal some genetic facts and traits of an individual.
According to the question, the two F1-hybrid pea plants for spherical seeds have the genotype of Rr and when these two genotypes are crossed with one another, it produces offspring with the genotypes RR, Rr, Rr, and rr. In this set of offspring, 2 of them have heterozygous genotypes.
Therefore, a genetic cross between two F1-hybrid pea plants for spherical seeds will yield 50% of plants with a heterozygous genotype in the F2 generation. Thus, the correct option for this question is C.

Explanation:
In a population of spiders there are three different sizes: small, medium, and large. ---The large spiders are easily seen by predators. ---Small spiders have a difficult time finding food. What will most likely happen to this population of spiders after many generations?
Answer: Over time the medium spiders will be most common out of the three.
Explanation: Because of natural selection the large and small spiders wil die leaving more medium spiders alive. So now the medium spiders can reproduce and make more medium spiders so there will be much more medium spiders compared the the small and large ones.

What is carrying capacity?
the maximum number of organisms that can
live in a population
the ability of the environment to provide
resources for a growing population
the maximum number of organisms an
environment can support for a long time
the maximum number of species that can
live in an ecosystem.
Answer:
The maximum number of organisms an environment can support for a long time
The maximum number of organisms an environment can support for a long time.
What is carrying capacity?Carrying capacity refers to the maximum population size of a particular species that a given ecosystem or environment can sustain indefinitely. It represents the balance between the resources available in the environment and the needs of the population. Once the population reaches the carrying capacity, the available resources may become limited, leading to increased competition for food, water, shelter, and other necessities.
This can result in population stabilization or fluctuations as the ecosystem tries to maintain equilibrium. Understanding the carrying capacity of an environment is important for managing and conserving populations and maintaining the long-term sustainability of ecosystems.

Answer:
Cytokinesis
Explanation:
The last stage of the cell cycle is cytokinesis, or the division of the cytoplasm. In animal cells the cell membrane pinches in half. In plant cells, a new cell wall begins to grow in an area called the cell plate located between the two new nuclei until they are separated into two new cells.
I require assistance. Oil is a fossil fuel used to run cars, heat up homes, and produce electricity. Oil can be removed from the bottom of the ocean through drilling. Drilling machines dig deep down into the Earth. When oil is found, pipes carry it to the surface. Sometimes, accidents happen that cause the oil to spill into the oceans. The oil can not only kill marine organisms, but when it reaches the surface of the water, some chemicals evaporate, become part of the atmosphere, and pollute the air.
Based on the passage, which resources and organisms are affected by oil spills? Select three options.

Many resources are affected by oil spills like air water land and the organisms in water are also affected.
What is an oil spill?When a liquid petroleum hydrocarbon is discharged into the environment, particularly the marine environment due to human activities, it is known as an oil spill.
What resources are affected by the oil spill?Water: It forms a layer over the water. It causes the death of marine organisms. It releases toxic components.Air: petroleum is made up of many components. Some are light and toxic like benzene, xylene, toluene and ethylbenzene. These are released into the air and pollute itLand: When spilled on land it prevents the absorption of water in the soil and hence affects the flora.What organisms are affected by the spill?Marine organisms are affected by the oil spill. It has a toxic and lethal effect on organisms.The insulating ability of fur-bearing mammals is affected.livers become large and the rate of respiration changes.the fin of fishes are eroded.reproduction is also adversely affected.To learn more about the oil spills and petroleum here,

Explain the role of co-dominant alleles in human ABO blood groups.
Answer:
Co-dominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB. Suzanne Hart, Ph.

How much energy do consumers obtain when they eat
Answer: it’s 10%
Explanation: Primary consumers only obtain a fraction of the total solar energy—about 10%—captured by the producers they eat. The other 90% is used by the producer for growth, reproduction, and survival, or it is lost as heat. You can probably see where this is going. Primary consumers are eaten by secondary consumers.
