4. What are two ways that celestial navigation/astronavigation and navigation by GPS differ?
Do they have anything in common?
Differences: Celestial navigation is completely based on the position of sun in the sky. Here, the use of angular measurements can exist among the celestial objects. It is less accurate than the GPS.
The ways that celestial navigation/astronavigation and navigation by GPS differ include:
Celestial navigation is less accurate than GPS.Celestial navigation is an ancient method of navigation while GPS is a newer method of navigation.Celestial navigation is the navigation by the sun, moon, stars, and planets. GPS which refers to the global positioning system refers to the navigation system that's space-based that is important for broadcasting accurate navigation pulses to the users.The global positioning system is also known to be the network of satellites that are used in determining the location of a particular thing.The similarity between them is that they are both ways of locating a particular thing since they're used for navigation.Read related link on:

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.

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.

Complete the flowchart to show the stages of cellular respiration and fermentation.
Cellular Respiration and Fermentation
Answer:
The stages of cellular respiration are: Glycolysis, pyruvate oxidation, Krebs cycle and phosphorylative oxidation.
The fermentation stages are: glycolysis and pyruvate regeneration.
Explanation:
Cellular respiration is a biochemical process that occurs in all aerobic organisms and aims to promote the obtaining of the necessary energy so that the cells can perform the activities they need to perform. Cellular respiration occurs in mitochondria and oxygen must be present in the process.
Fermentation is the biochemical process that replaces cellular respiration in organisms that do not survive in the presence of oxygen, the anaerobic organisms that are some fungi and bacteria. Fermentation also aims to produce cellular energy.
4 Select the correct answer. A family has a Y-linked disease that affects the father. What is the chance of a male offspring inh А. 100% OB. 50% Oc. 25% OD. 0% Reset Next
Answer:
Remember that males have an x and y chromosome, while women have two x chromosomes.
Explanation:
This means that a female offspring (daughter) inherits her father's only x chromosome and one of her mother's x chromosomes, while a male will receive his father's y chromosome and one of his mother's x chromosomes.
This means that the boy will necessarily inherit his dad's Y chromosome, and any diseases that it carries.
The chance of a male offspring inheriting the disease is
A) 100%
Answer:
Mother
Explanation:
This mutation needs two X chromosomes. Only the mother has two X chromosomes (XX). The father is male, so he only had one X chromosome (XY).
Check your understanding! Mark any that are correct.
Mutations are random.
Mutations are most beneficial and useful for an organism.
Mutations can occur in both DNA and RNA, which are nucleic acids.
Mutations can only occur during interphase.
Not all genes code for proteins.
Not all genes are “turned on” at a given time.
Substitution mutations typically result in a frameshift mutation.
Mutations can be genetically inherited.

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.
