Explanation:
In simple terms, the term bipedalism refers to a term used to classify organisms that are equipped and use two legs or limp to walk, stand, jump or run.
One other nonprimate animal that is also a biped is the ostrich. When we compare the bipedalism of an ostrich with our (humans) bipedalism we discover that in terms of
Speed; an ostrich can move faster than an average human, reaching speeds of up to 70 km/h (43 mph).
limb length; its limb length can range from 10 to 16 feet (120 inches to 192 inches) which is far greater than the average length of an adult human's legs.
Describe what happened to beaver colonies after 1995 (when wolves were reintroduced). Then describe the relationship between the number of beaver colonies and the willow tree ring area.
Answer:
Decreases.
Explanation:
Decrease occurs in beaver colonies when wolves were reintroduced in the area because wolves feed on beaver and as a result, the population of beaver decreases. There is a direct relationship between the number of beaver colonies and the willow tree ring area because willow tree is a source of food for beavers so if willow tree are more in the area, more food available for the beaver and they will increase in number.

how many muscle types do mollusca have ? discuss these types?
help me
Answer:
Mollusks can be segregated into seven classes: Aplacophora, Monoplacophora, Polyplacophora, Bivalvia, Gastropoda, Cephalopoda, and Scaphopoda. These classes are distinguished by, among other criteria, the presence and types of shells they possess.
The equation below shows a process that occurs in all green plants.
carbon dioxide + water + energy → glucose + oxygen
Which statement about this process is true and supported by the equation?
A: The process follows only the law of conservation of mass and not the law of conservation of energy because the number of atoms stays the same, but energy is used up.
B: The process follows only the law of conservation of energy and not the law of conservation of mass because energy is the same in the products, but the number of atoms increases.
C: The process does not follow either the law of conservation of mass or the law of conservation of energy because the number of atoms increases and the amount of energy is reduced.
D: The process follows both the laws of conservation of mass and of energy because the number of atoms stays the same, and the energy is used to make the products, is stored in the products, and is converted to heat.

Answer:
[tex]f=5.6\times 10^{14}\ Hz[/tex]
Explanation:
The resulting light have a wavelength of 532 nm.
We need to find frequency of the material. Let it is f.
The relation between frequency and the wavelength is given by :
[tex]c=f\lambda\\\\f=\dfrac{c}{\lambda}\\\\f=\dfrac{3\times 10^8}{532\times 10^{-9}}\\\\=5.6\times 10^{14}\ Hz[/tex]
So, the frequency of the light is [tex]5.6\times 10^{14}\ Hz[/tex]. Hence, this answer is correct.

How do the daughter cells at the end of mitosis and cytokinesis compare with their parent cell when it was in interphase of the cell cycle?
Answer:
The daughter cells have the same number of chromosomes and the same amount of DNA.
Explanation:
Mitosis is a process where the nucleus divides, so at first we have 46, and we need to bring it down to 23, because that is how much our cells can take, but after mitosis, the daughter cell will end up with 2 new cells, and it will have 23 chromosomes in each of the cells.

A pedigree chart is used to _______. (3 points)
A: predict percentage of offspring with a trait
B: predict genotypic probabilities
C: track inherited traits through generations
D: identify the genotype of parents
Answer:
A pedigree chart is used to track inherited traits through generations (option C).
Explanation:
A pedigree chart is a graphical representation, similar to a family tree, showing specific traits present in parents, children and relatives. It is a diagram commonly used in genetics.
A certain phenotype, product of genetic traits, is represented in a pedigree chart by pre-established symbols, which is useful for tracking inherited traits through generations.
The other options, predict percentage of offspring with a trait , predict genotypic probabilities or identify the genotype of parents require a Punnett square to be identified.Answer:

Explanation:
When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, a\an ________ in predatory fish caused a\an ________ in plankton feeding fish, which resulted in a\an ________ in\ herbivorous plankton with a consequent ________ in algae. Group of answer choices increase; increase; increase; decrease increase; increase; decrease; increase decrease; increase; increase; decrease increase; increase; decrease; increase increase; decrease; increase; decrease
Answer:
increase; decrease; increase; decrease
Explanation:
When Lake Mendota was completely covered with algae, biologists used the concept of trophic cascades to solve the problem by introducing predatory fish. When they did this, an increase in predatory fish caused a decrease in plankton feeding fish, which resulted in an increase in herbivorous plankton with a consequent decrease in algae.
With the introduction of predatory fish, a decrease in the population of zooplankton-eating fish would occur due to predation by the newly introduced fishes. This will cause the population of zooplankton to thrive or increase.
Zooplanktons feed on algae. Hence, an increase in their population will put pressure on the alga in the ecosystem and cause a decrease in their population.

Which of the following is not a example of heredity
Answer:
Where are the examples??????
Explanation:
Which of the following is the most effective argument for the improved treatment of animals in CAFOs?
The quality of animal products is improved when animal welfare is considered.
Many consumers are interested in buying from companies that consider animal welfare.
Animal welfare must be considered, as animals have the right to live free of confinement and cruelty.
Behavior in which the animal injures itself or others is less common when animal welfare is considered.
Answer:
Many consumers are interested in buying from companies that consider animal welfare.
Explanation:
Factory farms, also known as Operators of concentrated animal feeding operations (CAFOs) are interested in maximizing their production efficiency to increase their profits, regardless of the animals´ health and growing conditions. These factories tend to prioritize rapid growth and production over animal welfare, which might be an important reason to think that they do not care about the quality of their product, more than they do about their earnings.
Since during the last years, there is a sharp increase in the people´s conscientization of animal welfare and the conditions in which they are grown, probably the most effective argument for the improved treatment of animals in CAFOs is that many consumers are interested in buying from companies that consider animal welfare.
People who care about animal conditions will not consume animal products from factory farms, which eventually ends by affecting these factories´ profits. If CAFOs improve animal treatment and get higher animal welfare standards, they will have more people consuming their products, which is basically their main interest.
Answer:
animal welfare

A cloning vector is a short piece of DNA which can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes.
What is Cloning Vectors?
A cloning vector is defined as a short piece of DNA that can be stably maintained in an organism, and into which an external DNA fragment can be inserted for cloning purposes. This may be DNA taken from a virus, the cell of a higher organism, or it may be a plasmid of a bacterium.
Cloning vectors are plasmids that are mainly used to amplify DNA which replicate at high copy number in E. coli and contain a multiple cloning site.
Examples of cloning vectors are plasmids, cosmids, bacterial artificial chromosomes (BACs), and yeast artificial chromosomes (YACs).
Thus, a cloning vector is a short piece of DNA which can be stably maintained in an organism, and into which a foreign DNA fragment can be inserted for cloning purposes.

Assume a seed eating finch population is currently at carrying capacity and the availability of food decreases dramatically. What will happen to the carrying capacity
Answer:
This question lacks options, options are:
A.Carrying capacity will increase B.Carrying capacity will decrease C.Carrying capacity will remain unchanged. The correct answer is B.
Explanation:
Ecologists define 'carrying capacity' as the population of a certain species that a defined habitat can support indefinitely, without permanently damaging the ecosystem on which they are dependent,that is, the ecological carrying capacity of an ecosystem is the maximum growth limit of a biological population that the environment can support in a given period, without negative effects on that population or on the environment.
The Hardy-Weinberg equilibrium is a theoretical model that predicts the frequency of different genotypes in a population that is not evolving. A scientist studying the population genetics of the rainbow fish finds that the Hardy-Weinberg model predicts that the frequencies of the three different genotypes for the albino gene in a given lake should be as follow: AA: 49%, Aa: 42%, and aa: 9%. However, the scientist obtained a sample of 320 individuals of this species and found that the numbers of individuals for the different genotypes are: AA: 180, Aa: 120, and aa: 20.

The Hardy-Weinberg equilibrium is a theoretical model that predicts the frequency of different genotypes in a population that is not evolving. A scientist studying the population genetics of the rainbow fish finds that the Hardy-Weinberg model predicts that the frequencies of the three different genotypes for the albino gene in a given lake should be as follow: AA: 49%, Aa: 42%, and aa: 9%. However, the scientist obtained a sample of 320 individuals of this species and found that the numbers of individuals for the different genotypes are: AA: 180, Aa: 120, and aa: 20. Use the appropriate statistical technique to test (use alpha = 0.05) whether the observed genotype frequencies are consistent with eh Hardy-Weinberg model. State your conclusion.
Answer:
There is enough evidence to reject the null hypothesis. The genotypes are not in equilibrium. The genotype frequencies are consistent with the Hardy-Weinberg model.
Explanation:
Expected Number of individuals with each genotype: Each genotype´s frequency multiplied by the total number of individuals in the sample.
AA= 0.49 x 320 = 156.8
Aa= 0.42 x 320 = 134.4
aa= 0.09 x 320 = 28.8
Observed Number of individuals with each genotype:
AA= 180
Aa= 120
aa= 20
Chi square= ∑ ((O-E)²/E)
∑ is the sum of the terms O are the Observed individualsE are the Expected individualsAA= (O-E)² /E
AA= (156.8 - 180) ² / 156.8
AA= 538.24/156.8
AA= 3.433
Aa= (O-E)² /E
Aa= (134.4-120)² / 134.4
Aa=207.36/134.4
Aa= 1.543
aa= (O-E)² /E
aa= (28.8-20)²/28.8
aa= 2.69
X² = ∑ ((O-E)²/E) = 3.433 + 1.543 + 2.69 = 7.666
Freedom degrees = genotypes - alleles = 3 - 2 = 1
Significance level, 5% = 0.05
p value less than 0.05
Table value/Critical value = 3.841
7.666 > 3.84 meaning that the difference between the observed individuals and the expected individuals in each chamber is statistically significant.
There is enough evidence to reject the null hypothesis. The genotypes are not in equilibrium.
