Answer and Explanation:
Cross: aa Bb dd Ee x AA bb Dd Ee
We can calculate the probability of getting heterozygous individuals in the progeny by using the product rule. Assuming that these four genes assort independently (events that occur independently from each other), we can infer that the F1 will have the next genotypic proportions for each gene:
1) aa x AA
F1) 4/4=1 Aa
2) Bb x bb
F1) ½ bb
½ Bb
3) dd x Dd
F1) ½ dd
½ Dd
4) Ee x Ee
F1) ¼ EE
2/4 = ½ Ee
¼ ee
So, to know what the probability is that the F1 of being heterozygous for all loci, we must multiply the respective individual probabilities of getting a heterozygous genotype, like this:
1 Aa x ½ Bb x ½ Dd x ½ Ee = 1/8 AaBbDdEe
The right atrioventricular valve (tricuspid) regulates the opening between the _________ and the _________.
Answer:
The right atrioventricular valve (tricuspid) regulates the opening between the right atrium and the right ventricle.
Explanation:
Valves are gates that allow the connection between atria and ventricles. The two valves located on the right side (tricuspid and pulmonary) direct the incoming blood from the body to the lung, where it is oxygenated; from there it returns to the left atrium, to later pass through the mitral and aortic valves. The left atrium connects to the left ventricle through the mitral valve and the right atrium connects to the right ventricle through the tricuspid valve.
Describe what the results would look like if the data supports your hypothesis.
Answer:
Please see below
Explanation:
In such a case, the data will indicate a positive trend towards the outcome predicted in the dependent variable. However, the data has to show a significant difference (as indicated by p value) between the measured variables for it to be a valid support of the hypothesis.
In the carbon cycle, all animals must consume
other organisms because
A. they can not absorb enough carbon from water.
B. they cannot absorb carbon directly from the air.
C. they are in competition with plants for available
carbon.
D. they require carbon to perform photosynthesis.
Answer:
B. they cannot absorb carbon directly from the air.
Explanation:
Carbon cycle refers to the series of processes through which carbon is exchanged between living and non living components of the environment. During the carbon cycle, animal organisms feed on one another in order to obtain energy, a characteristics that makes them HETEROTROPHIC.
Unlike plants, animals cannot perform photosynthesis, which turns solar energy into biomass (carbon-based). Plants get their carbon source (CO2) directly from air via the stomata on their leaves. Animals, on the contrary, cannot get carbon this way, hence, they need to feed on other animals to get their carbon and energy source.

Which of the following intake forms is necessary to ensure no prior medical concerns for a client?
A. Liability waiver
B. Comprehensive client form
C. PAR-Q
D. Recovery assessment
Answer:
C. PAR-Q
Explanation:
PAR-Q is an acronym for Physical Activity Readiness Questionnaire. It is a form containing questions relating to the health status of a client that is about to undergo fitness training. The PAR-Q is one of the intake forms (infact one of the most important) required by a client to fill before starting the physical/fitness training.
The PAR-Q is used to assess a client's health state in order to make a decision on whether or not the fitness training will be commenced. It is the intake form necessary to ensure that there are no prior medical concerns for a client. If there are, the training might be suspended till medical advice is sought.
12. When considering gravity acceleration and the force of acceleration, what must be true?
A. The direction of acceleration must be perpendicular to the direction of the force.
B. The mass of the body must be the same as the acceleration of the body.
C. The direction of the force and the direction of acceleration must be opposite of each other.
D. The direction of the force and the direction of acceleration must be the same as each other.
PLEASE HELP ASAP
Answer:
The correct option is (D).
Explanation:
Newton's second law of motion gives the relationship between the force and acceleration of an object. It can be given by :
F = ma
It means that the force is directly proportional to both mass and acceleration. If the acceleration increase, force will increas. It would mean that "The direction of the force and the direction of acceleration must be the same as each other".
Evolution is biology's core theme that ties together all the other themes. This is because evolution explains
Answer:
The change in the inherited characteristics of organisms over successive generations.
Explanation:
Characteristics that defines a biological organisms are passed down from parent to offspring during sexual reproduction. These characteristic can change over time due to mutation of genes. The new characteristics can either become more dominant; if it enhances the organisms chances of survival, or can die away or even lead to the complete wipe out of the species, if it does not increase the odds of survival of the organism. The mechanism of the development, or eradication of these characteristics is through natural selection, and sexual selection.

Answer:
Smooth-surface decay.
Explanation:
Dental caries is a multifactorial infectious disease of the hard tissues of the tooth (enamel and dentin) that arises on the surface of the tooth and can spread to the pulp. Smooth-surface decay are dental caries that originate on the smooth surfaces of the proximal general teeth, or in the gingival third of the facial and lingual surfaces. This cavity forms when plaque builds up and bacteria are not killed on the flat surface of the teeth.

Bacterial species have evolved over millions of years to fill almost every available environmental niche on this planet. Despite this impressive radiation, bacteria are still limited by the availability of carbon and nitrogen sources for their metabolisms. Bacteria may express many different proteins required for uptake and utilization of these compounds for use in their metabolisms. Organic compounds containing carbon and nitrogen are required for both anabolic and catabolic reactions that comprise a cell’s metabolism. Not all bacterial species have the same abilities, so you can use this characteristic to differentiate bacterial species by determining which carbon- and nitrogen-containing media support the growth of the bacteria. Determine whether the following enzymatic reactions are anabolic or catabolic and place them within the correct bin.
1. Glucose is broken down into two pyruvates.
2. ammonia is added to glutamate to form glutamine.
3. four amino acids are linked together to form tetrapeptide.
4. a uracil base is added to a mRNA strand by RNA polymerase.
5. starches are digested into individual glucose molecules.
6. ribose and inorganic phosphate are bonded to form a nucleotide base.
Answer:
1. Glucose breaks down into two pyruvates. CATABOLIC
2. Ammonia is added to glutamate to form glutamine. Anabolic
3. Four amino acids join to form tetrapeptides. Anabolic
4. A uracil base is added to an mRNA strand by RNA polymerase. Anabolic
5. Starches are digested into individual glucose molecules. CATABOLIC
6. Ribose and inorganic phosphate join together to form a nucleotide base. Anabolic
Explanation:
Chemical reactions are classified as anabolic and catabolic depending on whether they form or disintegrate structures, yielding energy to the medium or taking energy from the medium.
Anabolic reactions are those that take energy from the environment and therefore synthesize very complex molecules, of various bonds such as glycogen, starch, among other polysaccharides.
On the other hand, catabolism leads to the destruction of the unions of a chemical product, that is why they have greater entropy and is thus the greatest disorder.
Catabolism releases energy to the environment, it releases it.
For an anabolic reaction to happen, there must be a catabolic one, since it takes the energy released by catabolism, and for a catabolism to happen, an anabolism must first have arisen, that is, the formation of a molecule or particle that is dissociates.

A cardiac muscle cell is: A. a voluntary muscle just like skeletal muscle. B. contracts spontaneously. C. is joined to other cardiac muscle cells by structures called intercalated discs. D. has numerous nuclei. E. Two of the statements above are correct
Answer:
E. Two of the statements above are correct i.e. options B and C
Explanation:
Cardiac muscles, also known as myocardium, are one of the three types of muscles found in the heart (the other two being skeletal and smooth muscles). Cardiac muscle cells are striated and branched in structure, with only one nucleus located centrally i.e. mono-nucleated.
Unlike the skeletal muscles, cardiac muscles are involuntary muscles controlled by certain parts of the brain. The cells that make up the cardiac muscles are connected to one another by structures called intercalated discs. Also, cardiac muscle cells contract spontaneously i.e. internally. Hence, options B and C are correct
