Suppose that a rabbit breeder notices two individuals in a litter with large, round noses and names this trait the clown trait. He obtains another rabbit that has a long, thin nose and names it the Pinocchio trait. After breeding the rabbits with unusual nose shapes to wildâtype individuals for several generations, he decides to cross rabbits from families with a history of the clown and Pinocchio traits. The first litter from this cross results in individuals of four phenotypes. The phenotypes are clown, Pinocchio, wildâtype, and heartâshaped noses. The pedigree illustrates the inheritance of these traits. Individuals 1 and 4 are siblings and are known to come from a true-breeding wild type line.
1. What is the most likely mode of inheritance for the clown nose?
a. -linked
b. X-linked dominant
c. X-linked recessive
d. Autosomal dominant
e. Autosomal recessive
2. What is the most likely mode of inheritance for the Pinocchio nose?
1. Sex-influence
2. X-linked dominant
3. X-linked recessive
4. Autosomal dominant
5. Autosomal recessive
Answer:
1. The probable method of inheritance for the nose is a male chromosome-linked recessive.
2. The probable method of inheritance for the Pinocchio nose is in the autosomal chromosomes, with a dominance factor.
Explanation:
1. The gene is observed to be expressed in males.
2. The gene of Pinocchio expression has been expressed from the parents with equal phenotype.

If the percent solute concentration is greater in the fluid outside a cell than inside a cell, how will the water flow
Answer:
If the percent concentration is greater in the fluid outside a cell than inside a cell, water will flow out of the cell. If the percent concentration is equal both inside and outside a cell, water does not move into or out of the cell.
Explanation:
How do the different diets of organisms affect their eating patterns?
Answer:The evolutionary history of hominins has been characterized by significant dietary changes, which include the introduction of meat eating, cooking, and the changes associated with plant and animal domestication. Decades of anthropological research have been devoted to elucidating this dietary history, in part because these shifts were likely associated with major anatomical and cultural changes (e.g., the increase in relative brain size and the advent of modern civilization via agriculture). However, this reconstruction is also crucial for understanding the evolutionary context of our modern diets and the diseases often associated with them.
In parallel with the historical reconstruction of hominin diets, molecular evolutionary analyses have been used to interrogate the genome for signals of genetic adaptations to different dietary regimes. A major advantage of many evolutionary genetic approaches is that they do not necessarily require strong assumptions about the specific genes and alleles that were targets of diet-related selective pressures. For this reason, evolutionary genetic analyses have the potential not only to inform existing adaptive hypotheses of hominin dietary history, but also to help generate new ones.
Here, we bring together these two areas of inquiry, namely anthropology and evolutionary genetics, to highlight their recent findings related to human dietary history and to discuss the limitations of different approaches. We start by providing a brief overview of the major dietary shifts in hominin evolution and discussing the evolutionary genetics methods and approaches used to identify signals of natural selection. We then review the results of genetic studies aimed at detecting the loci that played a major role in dietary adaptations and conclude by outlining the potential of future studies in this area.

Why are seeds an evolutionary advantage for seed plants?
Seeds allow for the transport of water and nutrients.
Seeds develop into adults without sexual reproduction.
Seeds protect and nourish young, growing plants.
Seeds provide the materials for photosynthesis.
Answer:
Seeds protect and nourish young, growing plants.
Explanation:
Seeds allow for young plants to be protected in the hard case of the seed.
Seeds also contain a food supply that allows for the young plants to be nourished.
So, seeds are an evolutionary advantage for plants because they protect and nourish growing plants.
The reason why seeds are an evolutionary advantage for seed plants is because: C. Seeds protect and nourish young, growing plants.
What is an evolution?Evolution can be defined as a process of gradual change in the characteristics and genetic pool (make-up) of the species of a living organism over several generations.
What is a seed?A seed refers an embryonic plant or a fertilized ovule which contains the plant embryo that are generally enclosed in a protective outer covering and are used for plant reproduction.
In conclusion, seeds are an evolutionary advantage for all seed plants is because they protect and nourish young, growing plants.

9.If you break an atom apart would it still behave like the element that makes it up? (yes/no)
Answer:
Yes.
Explanation:
The energy released in splitting just one atom is miniscule. However, when the nucleus is split under the right conditions, some stray neutrons are also released and these can then go on to split more atoms, releasing more energy and more neutrons, causing a chain reaction.

A student put some drops of lugols iodine solution into the water in the beaker shown to the right the water turned red after a short time the starch solution inside the dialysis tube and turn the black what function of the cell membrane was a student demonstrating
Answer:
diffusion through a selectively permeable membrane
Explanation:
The cell membrane selectively allows certain substances to enter or leave a cell . This implies that cell membranes are selectively permeable; they allow some substances to pass through, but not others.
Direct transport of materials across the cell membrane is often passive. Passive transport does not require energy to occur. Passive transport is the movement of substances from a region of higher concentration to a region of lower concentration. A concentration gradient is always required.
The diffusion through a selectively permeable membrane is an example of passive transport.
The iodine moves into the dialysis tube across the semi permeable cell membrane from a region of higher concentration to a region of lower concentration in response to a concentration gradient.

Which element has seven energy levels the only one valence electron
Answer:
Your answer is chlorine.
Explanation:
Valence electrons help in predicting chemical reactions. For example, since hydrogen (H) is in group 1, it has 1 electron in its outer energy level. Chlorine (Cl), which is in group 17, has 7 electrons in its outer energy level and is one electron short of having a "full" outermost energy level.

The Miller-Urey experiment led to a remarkable conclusion: many of the organic building blocks of life were super easy to make. This caused many biologists to think that we were right on the cusp of being able to create life in the lab. However, those hopes were not realized and we are not at all close to creating or "inventing" life. Another major problem is that:

PAL: Cadaver > Muscular System: Upper Limb > Lab Practical > Question 4
Identify the highlighted muscle.
Answer:
Brachialis
Explanation:
The Brachialis is an anterior skeletal arm muscle that extends from the medial arm to the superior area of the forearm. The brachialis fibers originate in the anterior part of the humerus and direct to the inferior part of the elbow, where they insert in the upper region of the ulna and distal radius. This muscle is an elbow flexor being used in every movement needed to approximate the anterior part of the forearm to the arm. It is a very thick and powerful muscle that acts with high speed.
The upper limb or arm is the functional unit of the human body, which is made up of 6 different muscular regions, such as the pectoral, upper arm, hand, posterior forearm, and anterior forearm.
In the given image of the upper extremity, the muscle highlighted is the brachialis.
Brachialis anticus or the Teichmann's muscle is present in the upper extremity, which helps in the flexion of the elbow. The muscle is situated in the deeper biceps brachii and makes up the floor region of the elbow pit.
The muscle originates in the anterior part of the humerus and directs the inferior of the elbow. The brachialis muscle is one of the largest flexors of the elbow, which provides the movement or flexion of the forearm at the elbow.
Therefore, the given image is of the brachialis muscle.

Meaning of invertebrate and vertebrate
Answer:
Vertebrate:spine Invertebrate:no spine
Explanation:
Answer:
Invertebrates are animals that do not have backbones. 95%-97% of the members of the animal kingdom are invertebrates such as sponges, jellyfishes, squids, and roundworms.
Vertebrates, on the other hand, are animals with a backbone or a vertebral column and are composed of six groups: mammals, birds, reptiles, amphibians, and fishes. Humans are members of the vertebrates family too but are sometimes exempted from the list when the discussion leans towards animals.
