Create cladograms for the primates and animals groups (skip the Artiodactyla for now). These Claudio grams are a little more complex and you may have to include multiple branches at the same level such as in the example shown at the right. When you had built Cladograms with the lowest possible parsimony score compare them to the accepting Cladogram

A population of wolves migrate North in search of food. As the wolves travel they enter a region that has long, snowy Winters. This makes them better able to sneak up on prey.
A.) Give two reasons that the population is not a Hardy Weinberg equilibrium.
C.) How are the allele frequency change in the wolf population
Answer:
A, This is the case of selective pressure of environmental factors like snow, due to which favored the expression of the allele that formed white coat phenotype. This is not a Hardy-Weinberg principle, in which no selective pressure is applied. The relative frequencies of the alleles change in the gene pool, due to selective pressure, and the expressed alleles are often significant for survival in those conditions.
b,HW equilibrium means no selective pressures like the long, snowy winters selectively favoring the white coat phenotype over the other coat phenotypes. Selective pressures change the relative frequencies of the alleles in the gene pool. It also means the population does not have either immigration or emigration to change the ratios of alleles in the gene pool The Hardy-Weinberg principle of genetic equilibrium tells us what to expect when a sexually reproducing population has no selection pressure, no gene flow, no nonrandom mating, not even genetic drift.

Phillip Gingrich finds an S-shaped bone in this partial skull, a sigmoid process, which is unique to
one particular order of animals in the water today... which one?
Answer:
A primitive whale which he named Pakicetus.
Explanation:
Philip Gingrich is a vertebrate paleontologist at the University of Michigan. He has performed extensive research on whales at the Egyptian desert of Wadi Hitan. His research team member discovered a skull whose braincase was bigger than that of a walnut. Gingerich was able to link the small-brained animal, to an early whale.
The auditory bulla had an s-shaped bony crest known as the sigmoid process and these two features helped whales to hear in water. The case, however lacked other features that helped whales hear beneath the waves. This led Gingrich to the conclusion that the unknown animal was semi-aquatic. This finding also lent credence to the possibility of whales evolving from terrestrial animals.

what is the advantage and disadvantage of the Ocotillo and Hummingbird relationship
Advantages:
The plant is an integral member of the regional desert ecosystem and native pollinators such as hummingbirds and carpenter bees consume ocotillo nectar for nutrients. The hummingbird and the ocotillo have an important plant-pollinator relationship, as the hummingbird relies upon the flowers for a nectar source.
The relationship between Ocotillo and Hummingbird is an example of a mutualistic relationship, which means that both species benefit from each other's presence.
What are the various advantages and disadvantages of the relationship ?The advantages and disadvantages of this relationship can be described as follows:
Advantages:
Ocotillo provides a source of nectar for hummingbirds, which is an important source of energy for their high metabolic rate.
Hummingbirds are efficient pollinators of Ocotillo flowers, which helps to ensure their reproduction and genetic diversity.
Ocotillo provides a nesting site for hummingbirds, where they can raise their young in safety from predators.
Disadvantages:
The relationship between Ocotillo and hummingbirds is specific and may not be beneficial to other species of plants or animals.
Ocotillo is adapted to living in arid environments and may not provide a suitable habitat for some other species of birds or animals.
If the population of either Ocotillo or hummingbirds were to decline significantly, it could affect the survival of the other species in the mutualistic relationship.
Overall, the advantages of the Ocotillo-Hummingbird relationship outweigh the disadvantages, and this mutualistic relationship is an important part of the ecosystem in which they both live.

Why are green plants considered producers?
Green plants directly absorb sunlight to make energy.
Green plants contain chlorophyll.
Decomposers consume green plants.
Green plants are eaten by secondary consumers.
Answer:
The organisms that are capable of preparing their own food from simple inorganic substances like carbon dioxide and water by using sunlight energy in the presence of chlorophyll are called producers. The green plants synthesize their own food through the process of photosynthesis and thus are called the producers.plants produce food for themselves, they are known as producers.The two birds shown in Figure A and B are found on one island. The bird species in figure A is moved to a new island, where food size and shape are different from the food found in their current island. The birds left behind (Figure B) on the original island continue to grow and reproduce.
What changes might a scientist expect to see in the species?
A.
The birds on the old island would not change over time and evolve.
B.
The birds on the new island would evolve over time and die out.
C.
The birds on the old island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
D.
The birds on the new island would evolve over time and develop adaptations in their beaks to allow them to eat new types of food.
Answer:
D.
Explanation:
because if the birds in figure A move to the new island with new food size and shape they will adapt to the food

Annie wants to have children, but she and her husband have been unsuccessful so far.
Do her cells in her ovaries need to go through mitosis or meiosis? Choose one, and
explain why.
Answer:
meiosis
Explanation:
The germ cells that enter meiosis become oocytes, the source of future eggs. Consequently, females are born with a finite number of oocytes arrested in the first meiotic prophase. Within the ovary, these oocytes grow within follicle structures containing large numbers of support cells. (i don't know if the explanation is correct but i know that it is meiosis)
5: What does water have to do with our metabolism?
Answer:
Studies have shown that drinking 17 ounces (0.5 liters) of water increases resting metabolism by 10–30% for about an hour ( 22 , 23 ). This calorie-burning effect may be even greater if you drink cold water, as your body uses energy to heat it up to body temperature ( 21 , 24 ). Water can also help fill you up.

O The human and horse are the most closely related organisms with the fewest differences in their amino acid sequences.
O The monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences.
Answer:
d
Explanation:
d
The monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.
What are amino acid?Amino acid is defined as any of the elements present in both plants and animals that come together to produce a substance (protein), which is essential for a healthy body and for growth. The metabolism of amino acids plays a crucial role in many biological processes that take place inside the human body.
An examination of the first complete sequence of the gorilla genome suggests that humans and gorillas last coexisted 10 million years ago. The gorilla is the last of the surviving great apes, including humans, chimpanzees, orangutans, and gorillas, whose entire genetic sequence has been compiled.
Thus, the monkey and gorilla are the most closely related organisms with the fewest differences in their amino acid sequences. Hence option d is correct.
