In bunnies long ears are dominant over short ears. If two heterozygous bunnies are crossed, what is the probability their offspring will have the long ear phenotype? 1. 25% 2. 50% 3. 75% 4. 100%
Answer: 75%
Explanation:
See my picture for my work. Use a punnett square.
Answer: 75%
Explanation:
Heterozygous means that one allele would be dominant, and the other would be recessive. I will use B for the dominant allele, and b for the recessive allele.
Next, create a Punnett square (look at the pic).
To make the Punnett square, draw a 2 × 2 table. Put Bb on the top (one over each column) and Bb on the left side (one next to each row). Cross multiply. Remember to always put the dominant allele (in this case, B) in front of the recessive allele (in this case, b). The dominant allele will always be exhibited in the organism. So, the answer is 75%, since 3/4 of the different combinations of alleles is long ears.

What is a limiting factor and how can limiting factors limit the size of a
population?
A. A resource that is so scarce (in restricted quantity) that it limits the size of a
population is called a limiting factor. Any single resource can be a limiting factor
to a population size. For example, the amount of water available can affect the
number of plants that can grow in an area.
B. A resource that is so plentiful that it limits the size of a population is called a
limiting factor. Any single resource can be a limiting factor to a population size.
For example, the amount of water available can affect the number of plants that
can grow in an area.
Answer:
A. A resource that is so scarce (in restricted quantity) that it limits the size of a population is called a limiting factor. Any single resource can be a limiting factor to a population size. For example, the amount of water available can affect the number of plants that can grow in an area.

3.When Watson and Crick built and proposed the DNA structure, they determined three important features.
What were the three features they proposed? Select all that apply.
Multiple select question.
A) Two outside strands consist of alternating deoxyribose and phosphate.
B) Two outside strands consist of alternating ribose and phosphate.
C) Guanine and cytosine bases pair to each other by two hydrogen bonds.
D) Guanine and cytosine bases pair to each other by three hydrogen bonds.
E) Guanine and adenine bases pair to each other by three hydrogen bonds.
F) Cytosine and thymine bases pair to each other by two hydrogen bonds.
G) Adenine and thymine bases pair to each other by three hydrogen bonds.
H) Adenine and thymine bases pair to each other by two hydrogen bonds.
According to Watson and Crick, DNA replication used each strand's nucleotides as a template for new strands. Thus,option A, D, H is correct.
What is the Watson and Crick model about DNA?Watson-Crick DNA structure. The molecule of DNA is a double-stranded, helical structure. It consists of two sugar-phosphate backbones on the outside and nitrogenous base pairs on the inside, bound together by hydrogen bonds.
DNA behaves like a double helix made up of two protracted, intertwined helical strands.
In their model, the bases along one DNA strand matched the bases along the other DNA strand. Each DNA strand comprised discrete units known as bases.
Therefore, Watson and Crick built and proposed the DNA structure, which determined important features of DNA.

A container holds an element and a compound that are not chemically combined. Is this an element, a mixture or a compound?
Answer:
Mixture.
Explanation:
Mixture can be defined as a combination of two or more substances which are present in varied proportion and can be visibly seen by with our naked eyes.
In Science, there are two (2) main types of mixture and these are;
I. A homogeneous mixture: it can be defined as any liquid, solid or gaseous mixture which has an identical or uniform composition and properties throughout any given sample of the mixture. In Chemistry, all solutions are considered to be a homogeneous mixture. For example, aqueous hydrogen chloride is a homogeneous mixture of water and hydrogen chloride.
This ultimately implies that, in a homogeneous mixture, the different parts are uniformly (evenly) distributed.
II. A heterogenous mixture: it can be defined as any mixture which has a different or non-uniform composition and properties throughout any given sample of the mixture. This ultimately implies that, the constituents of a heterogenous mixture always remain separate in the sample and as such comprises of two or more phases.
For example, a mixture of sand and coffee is simply a heterogenous mixture and can easily be separated into their various components.
In this scenario, a container holds an element and a compound that are not chemically combined. Thus, this is a mixture.

Read this Pulmonology Consult excerpt:On physical exam, the patient is alert. He takes occasional pauses when he says long sentences, but otherwise, he is not in any distress. He has an occasional cough during his exam. His skin is pink and dry, and his lips are moist. His heartbeat is regular in rate and rhythm, without a murmur. On lung examination, he has whispered pectoriloquy on the right side with decreased breath sounds. He does not have any retractions or nasal flaring noted. His liver and spleen are not large.According to the excerpt, what was found upon lung examination on the right side?A. "Whispered pectoriloquy" - a chest that protrudes like the keel of a ship when the patient whispersB. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is presentC. "Retractions" - reverberations in the chest when it is struckD. "Retractions" - a dull sound in the chest when it is struckE. "Whispered pectoriloquy" - a chest that is hollowed out when the patient whispers
Answer:
B. "Whispered pectoriloquy" - "speaking from the chest"; used as a means of finding masses in the lung. The whispered word is audible in areas where fluid or a mass is present
Explanation:
Auscultation in medicine, is the action of listening to sounds from the heart, lungs, or other organs, usually using a stethoscope, in order to perform medical diagnosis.
Auscultation is performed for the purposes of examining the circulatory and respiratory systems, as well as the alimentary canal. The procedure is best performed in a quiet examination room. A stethoscope is used to magnify internal sounds. Small changes in breath sounds are carefully observed in order to make a diagnosis.
Whispered pectoriloquy is used to detect vocal resonance. It is used as a means of finding masses (consolidations e.g. pus) in the lung and is performed by having the patient quietly whisper a word. If fluid or a mass is present, words that are whispered may be heard clearly.

Answer:
1) As soon as the paper cuts into the cells of your skin, your body springs into action. First, blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.
The process is called Blood clotting.
2) The cell that are made will have the same same amount of DNA/chromosomes.
3) Chromosomes come in pairs. Normally, each cell in the human body has 23 pairs of chromosomes (46 total chromosomes). Half come from the mother; the other half come from the father. Two of the chromosomes (the X and the Y chromosome) determine your sex as male or female when you are born.
