Answer:
true
Explanation:
It's like zebras can never have the same stripes. Nothing can be created exactly the same.
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

Answer:
1. Black
2. Yellow
3. Bb (or BB)
4. bb
Explanation:
So they breed two black fur coats and get 75% black fur. This means that Bb is 75% too, making it black fur. The 25% (recessive) would be yellow.

O The gorilla and human are the most closely related organisms with the fewest differences in their amino acid sequences.
O The chimp and human are the most closely related organisms with the fewest differences in their amino acid sequences.
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.

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.
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.Which two processes cycle carbon directly between the atmosphere and biosphere?

When blood is flowing through a vena cava, which main blood vessel will it flow through next?
A hepatic portal vein
B hepatic vein
C pulmonary artery
D pulmonary vein
Answer:
C.
Explanation:
When the ventricle is full, the tricuspid valve shuts. This prevents blood from flowing backward into the right atrium while the ventricle contracts.
As the ventricle contracts, blood leaves the heart through the pulmonic valve, into the pulmonary artery and to the lungs, where it is oxygenated.

3. The sequence of nitrogenous bases is unique to each organism. The sequence of the
bases in DNA is most important for which of the following?
BB, Bb and bb are examples of?
dominant
recessive
genotypes
phenotypes
BB, Bb and bb are examples of genotypes. Thus, the correct answer is genotype.
A genotype is the genetic constitution of a trait in an individual. It is the genotype that results in the particular phenotype. Phenotype is the observable result of the trait.
Capital letter indicates that the allele is dominant and for recessive allele, small letter is used. Thus, B indicates dominant allele of that trait and b indicates recessive allele for that trait.
Depending on the genotype, the individual can be homozygous dominant, homozygous recessive or heterozygous for a trait.
In this case, BB is for denoting homozygous dominant, Bb is for heterozygous dominant and bb is for homozygous recessive.

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.

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.

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)
