EMS personnel often have medications, defibrillators, and other equipment that can stabilize a critical patient during transport.
Explanation:
For traits controlled by a single genetic locus, dominant phenotypes are expected to occur at a frequency of approximately 75%, in a randomly mating population.
true or false and why
Answer:
True.
Explanation:
The dominant phenotypes are expected to occur at a frequency of approximately 75%, in a population because of its dominant nature which allows them to appear in the physical structure of the organisms. In most of the offspring, the dominant allele shows their characteristics in the population whereas the recessive allele are hidden in that organisms and we can't see them in the physical appearance of the organisms.

TRUE OR FALSE: DINOFLAGELLATES IS A GROUP OF BACTERIA THAT USED TO BE CLASSIFIED AS ALGAE
Answer: True
Explanation:
Match the following prokaryotic classes with differing modes of metabolism with the appropriate descriptions - obligate anaerobes - Facultative anaerobes - Aerotolerant anaerobes - Obligate aerobes A. can shift their metabolism between anaerobic and aerobic modes B. Oxygen-sensitive, can only use anaerobic mode of nutrition C. unable to survive for extended periods in the absence of oxygen. They require oxygen for cellular respiration. D. cannot conduct cellular respiration but are not damaged by oxygen when it is present
Answer:
- Obligate anaerobes: B
- Facultative anaerobes: A
- Aerotolerant anaerobes: D
- Obligate aerobes: C
Explanation:
Obligate anaerobes are microorganisms that dead in normal atmospheric oxygen (O2) levels (around 21%). Some examples of obligate anaerobes are procaryotic bacteria such as Clostridium, Fusobacterium, Actinomyces and Peptostreptococcus. Facultative anaerobes are organisms that can grow without O2 and produce energy by fermentation, but they can produce more energy (ATP) by the aerobic respiration mechanism. Facultative anaerobes include both prokaryotic (e.g., Escherichia coli) and eukaryotic (e.g., Saccharomyces cerevisiae) organisms. Aerotolerant anaerobes are microorganisms that can live in O2 atmospheric conditions, but they use fermentation as cellular mechanism to produce energy (ATP). Some examples of aerotolerant anaerobes are lactobacilli and streptococci (bacteria) found in the oral microbiota. Finally, obligate aerobes are organisms that can grow only in normal O2 conditions and metabolize foods through cellular respiration, a process more energetically efficient than fermentation. An example of an obligate aerobe is the human species.

Mitosis and meiosis are cell division mechanisms that lead to different numbers of daughter cells. Which explanation best describes how these two processes maintain continuity?
meiosis :cell division that produces reproductive cells in sexually reproducing organisms
mitosis:cell division in which nucleus divides into nuclei containing the same number of chromosomes
meiosis nucleus divides twice and produces 4 daughter cells which are not genetically the same
mitosis necleus divides ones and produces two daughter cells which are genetically the same
The opening and closing of the heart valves is caused by Multiple Choice action potentials within the cusps of the valves. pressure changes of alternating contraction and relaxation during the cardiac cycle. contraction and relaxation of papillary muscles that pull on heart strings. contraction of the smooth muscle in the walls of the great vessels leaving the heart.
Answer:
pressure changes of alternating contraction and relaxation during the cardiac cycle.
Explanation:
In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.
Generally, the cardiac cycle occurs in two (2) stages;
I. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.
II. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.
Hence, the opening and closing of the heart valves is caused by pressure changes of alternating contraction and relaxation during the cardiac cycle.

In dust bunnies, short ears are dominant to long ears. If a heterozygous female mates
with a long ear male, what are the chances their offspring will have short ears?
Answer:
50% or 1/2
Explanation:
This question involves a single gene coding for ear length in dust bunnies. The allele for short ears (S) are dominant to the allele for long ears (s). This means an heterozygous individual (Ss) will possess short ears.
According to this question, If a heterozygous female (Ss) mates with a long ear male (ss), the parents will produce gametes as follows:
Ss - S and s
ss - s and s
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Ss, Ss, ss, ss
- Ss (1/2 or 50%) offsprings will have short ears.
- ss (1/2 or 50%) offsprings will have long ears.
How many alleles are typically present in a genotype?
Answer:A genotype is the combination of two alleles, one received from each parent. The expression of a genotype is called the phenotype and the specific combination of the two alleles (the genotype) influences the physical expression (the phenotype) of the physical trait that the alleles carry information for.

Which of the following scenarios is an example of temporal isolation?
A.
Fossil evidence suggests that a number of members of one squirrel species evolved over time into two separate species, each on opposite sides of the Grand Canyon.
B.
Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.
C.
Two species of tree crickets live in a Costa Rican dry forest. Their habitats and ranges overlap. The two species never interbreed because the calls of the males are different and do not attract females of the other species.
D.
Indian paintbrush flowers vary greatly in color. Bumblebees form a search image for the most average common color and preferentially pollinate those flowers.
Answer:
B. Black-eyed Susans and daisies used to be part of the same species. A random mutation in a subset of a population caused one group to release their pollen three weeks before the other, causing interbreeding to cease.
Explanation:
Temporal isolation, where temporal relates to time. So temporal isolation is the process where two populations will reproduce at different times/different seasons and therefore cause a split in species. In this case, we see the flowers release pollen at different times and caused a split into two distinct species.

The _____ on the out side of the virus are "sticky" and attracted to specific molecules on the outside of animal cells. A. Protein Spikes B. Carbohydrate Molecules C. Cholesterol Markers
Answer:
A. Protein Spikes
Explanation:
A viruses are defined as the quintessential parasites in the living world. They are a chain of the nucleic acids that lives in a host cell. Without the host cell, all the viruses cannot carry out their life sustaining activities or functions. They are always housed in a protein layer or a protein coat. All the viruses contains the RNA or the DNA. The protein spikes which is on the outside of a virus are "sticky" and they are attracted to the specific molecules of the outside of an animal cells.
