Answer:
Good environmental conditions and food availability.
Explanation:
Good environmental conditions and food availability are the factors that simulates the growth of parasite population in an animal with the passage of time. Yes, drug can reduces the population of parasites but all parasites can't be removed because some gain resistance against that chemical which allows them to survive in that environment so good environmental conditions and food availability increases population of parasite.

Name six desired properties when engineering protein.
Answer:
Site saturation mutagenesis is a PCR based method used to target amino acids with significant roles in protein function. The two most common techniques for performing this are whole plasmid single PCR, and overlap extension PCR. Whole plasmid single PCR is also referred to as site directed mutagenesis (SDM).

Explanation:
A food development company is interested in making on-the-go powder-based snacks in which consumers can "just add water" before eating. During market tests there are complaints that the powder does not dissolve well in water.If you were a food scientist, how might you modify the formula so that it will more easily dissolve in water? Provide your answer in 1-2 complete sentences.
The correct answer to this open question is the following.
Although there are no options attached we can comment on the following.
I might modify the formula so that it will more easily dissolve in water in the following way. I would ask my scientist in the laboratory to modify the formula. To make the formula more soluble when it makes contact with water, the addition of polar hydrophilic side groups to the molecule will help the formula to be soluble.
That is why it is very important to do focus groups to taste the product before launching it commercially and send the product to the stands of supermarkets, pharmacies, or grocery stores. If it is not previously tasted, you could encounter many difficulties. Furthermore, the FDA requires the best quality of the product so you have to make sure it works as it says in your advertisement.
The gene for a long neck also gives stronger, faster muscles, which gives tortoises with this trait
an advantage in catching insects. How would this advantage affect the population of tortoises from
Generation 1? How may that affect subsequent generations?
Answer:
it would help them thrive
Explanation:
because it anables them to catch more with there stronger faster necks
The shift in the traits of tortoises in the population states how natural selection drove the evolution of the tortoises.
Why do tortoises shift in their traits?During the evolution, with an extended period of time, the shorter vegetation became less available and tortoises with short necks had the disadvantage to survive in that area.
Tortoise develops genes for a long neck and having stronger, faster muscles, which gives tortoises with this trait an advantage in catching insects.
This natural selection helps the tortoises, to survive by catching more food in a particular area, it states tortoises with long necks are the only tortoises living during evolution.
Therefore, this advantage increases the survival rate of the tortoise population.

What letter is the second layer of the rock?
Answer:
Soil is a basic and fundamental natural resource, which took millions of years in its formation, resulting from the processes of disintegration and decomposition of rocks due to weathering. As much as many rocks, due to their hardness levels, seem indestructible, they all end up decomposing, even if slowly. Weathering is the general process that causes the deterioration of rocks. He is responsible for producing all the clays, all soils and dissolved substances that end up carried by rivers to the oceans. We can subdivide it into two types: chemical weathering and physical weathering. The first occurs when the minerals of a given rock undergo a chemical alteration or dissolution – and here the action of water is very important. The second occurs when there is a fragmentation of solid rock, through mechanical processes that do not change its chemical composition. Both reinforce each other. The smaller the pieces of rock created by physical weathering, the greater the surface for chemical weathering to act.
Rocks, reduced in particles through weathering, can accumulate as soil or, through erosion, be transported or deposited in the form of sediments somewhere else. Erosion is then defined as the process in which weathered materials (i.e., dismantled into smaller mineral fractions) are displaced or removed from their origin, usually by the action of water or air currents. A third geological process that should be mentioned is the dispersion of mass, which usually moves in isolated events, downhill, terrestrial materials modified or not by weathering, including large fragments of unchanged rocks.

Explanation:
Why do animals become adapted to their environments?
Answer:
An adaptation is a way an animal's body helps it survive, or live, in its environment. Camels have learned to adapt (or change) so that they can survive. Animals depend on their physical features to help them obtain food, keep safe, build homes, withstand weather, and attract mates.
Explanation:
:)
Answer:
All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space. ... An animal may adapt to its habitat in different ways.

The function of pure lines: ?
Answer:
The definition of a pure line is a result of inbreeding where animals or plants have certain characteristics that are the same through generations. An example of a pure line is the result of inbreeding of a certain flower to help it fight off diseases.
Corn kernels can be high in starch (starchy) or high in sugar (sweet). The allele for starchy kernels (H) is dominant to the allele for sweet kernels (h). Each kernel on an ear of corn represents an individual offspring. A particular ear of corn has 92 starchy kernels and 88 sweet kernels. What are the MOST likely genotypes of the parent corn plants that produced this particular ear of corn?
Answer:
Hh, Hh
Explanation:
The allele is the two or more variants of a specific trait present on the genes of the organism that is responsible for giving a particular physical and genetic attribute. The allele can be dominant or recessive.
The most likely genotype of the parent is Hh and hh.
How to know the genotype of the parent plant?The genotype of the parent plant can be estimated by crossing the heterozygous F1 generation with the recessive purebred parent plant. This type of cross is called a test cross.In the question, the offspring with the starchy and the sweet kernels is approximately in a 1:1 ratio. The offspring can be heterozygous dominant for the starchy kernel and purebred recessive for the sweet kernel.The heterozygous dominant offspring is crossed with the recessive purebred parent plant and will give the genotype.Thus, the genotypes are Hh and hh.

Directional selection differs from stabilizing selection in that:
a.Directional selection favors one extreme phenotype, whereas stabilizing selection favors intermediate over extreme phenotypes
b.Directional selection requires new mutations whereas stabilizing selection uses existing variation
c. Directional selection operates only in small populations, whereas stabilizing selection only works in large populations
d. they both do nothing, these are terms I made up while writing this retake
Answer:
a. Directional selection favors one end of the phenotype distribution, whereas
stabilizing selection favors intermediate over extreme phenotypes
Explanation:
Directional selection is called directional because it favors one phenotype over another, and stabilizing selection finds a balance between phenotypes.
Directional selection differs from stabilized selection in that it prioritizes one end of the phenotypic distribution, but stabilized selection prioritizes the middle over extreme phenotypes.
What is phenotype selection stabilization?The stabilized choice is the opposite of a destructive choice. Prefer intermediate varieties rather than individuals with extreme phenotypes. Stabilization of choice tends to remove more serious phenotypes and results in reproductive success of standard or average phenotypes.
What is an example of a stabilization choice?Stabilization of selection If the evolutionary pressure selects for two extremes of the trait, the population experiences stabilization of selection. For example, plant height can be affected by stabilizing choices. Plants that are too small may not be able to compete with other plants for sunlight.
