Explanation:

By human calendar days the Mesozoic era lasted for 67,890,000,000 days.

Mesozoic as a word means 'middle life,' and this was the period of dinosaurs. This time period comprises of the Triassic, Jurassic, and Cretaceous periods. The Mesozoic Era lasted from about 252 million years ago to 66 million years ago, a total of approximately 186 million years.

Assuming that the human calendar year is 365 days, then the Mesozoic Era would last for 186,000,000 years x 365 days/year = 67,890,000,000 days in human calendar days.

Answer:

Selectivity in choosing a mates

Geographic barriers separating subpopulations.

Explanation:

Selectivity in choosing a mates is a factor in which individuals can mate with each other. Some individuals tend to choose a sexual mates that posses some traits or characteristics that attract them to each other and because of the observable character, similar individuals attracted to each other mates.

Geographic barriers separating subpopulations is another factor that make similar organism or individuals to mates.

When there is geographic separations or demarcation between individuals in a species and they are separated from other subpopulations .. They tend to mate with each other in the same geographic location and cannot mate with other subpopulations that is outside their own geographic location. These is common in animals.

1. Newton's first law of motion projects that a object at rest will remain at rest, and a object in motion will remain in motion with a constant velocity, until or unless a force is acted upon by the external environment.

2. Newton's second law of motion projects that the acceleration of an object is considered to be directly proportional to the net force acting on the object and generally inversely proportional to its mass.

3. Newton's third law of motion projects that for every action, there is an equal and opposite reaction.

The first law is also renowned as the law of inertia. The second law thoroughly distinguishes the relationship between applied force and the rate of change of momentum. And finally the third law is also know as  the law of action and reaction because it depends on the type of stimulus that is experienced from the environment when the individual is applying force.

Introduction to Biology: Scientific method, experiment.

An experiment is the part of the scientific method where the hypothesis is tested.

It should be made under controlled conditions, because usually the goal is to see how a variable is affected by other. To be able to observe this, is important to have a control group and an experimental group in the samen conditions, only changing the variable that is being study.

If we look at the answers, we see that in option A doesn't have a controled environment and doesn't change anything between the plants. Option B has two groups with diferent food, but it doesn't measures anything. Option C is non an experiment because is not changing anything. But option D has a control and an experiment group with different diets and it measures their effect.

So, the correct option would be D. Twenty mice are fed high-protein diets, another 20 mice are fed their usual diet, and their weights are measured after three weeks.

The answer responses are:

In terms of question 5, A. The mutant DNA codes for the amino acid tyrosine (Y), while the normal DNA codes for a stop codon. The person with this mutation will not be diabetic because the protein product will be truncated and not functional.

B. The mutant DNA still codes for the amino acid leucine (L), although it is coded for by a different codon. Depending on the exact location of the mutation, this person may or may not be diabetic. If the mutation occurs in a critical region of the insulin gene that affects its function, the person may be diabetic. However, if the mutation occurs in a non-critical region, the person may still be able to produce functional insulin.

Therefore, Based on the amino acid sequences, the human and chimpanzee are the most closely related organisms. The two sequences are almost identical, differing only by a single amino acid at position 2. The pig and cricket sequences are much more different from the human and chimpanzee sequences, differing at multiple positions.

Generally, the way in  which runoff water will flow from your property is to the area with lower elevation and collect at the lowest point and the runoff water will collect and flow in rivers etc.

This can be described as the part of the water cycle that flows over land as surface water instead of being absorbed into groundwater as  a result of it no longer sufficiently rapidly infiltrating the soil.

Runoff water will flow from your property is to the area with lower elevation and collect at the lowest point and the runoff water will collect and flow in river which is why it is an important process of the water cycle in the ecosystem.

The correct answer is the last one, The median and the mode are the same and the mean is greater than the median and the mode. Both the median (the medium value when we sort them from lowest to highest) and the mode (the most frequent value) are 2.1. The mean (the average) is 2.15.

A trait that is usually expressed only when an organism has two identical alleles for the trait is called a "recessive trait." When an organism has two different alleles for a trait, the trait that is expressed is called a "dominant trait."

Explanation:

The incorporation of 14C from carbon dioxide into sucrose and its translocation through the phloem is an important process that helps to fuel growth and metabolism in plants.

Here is an outline of how 14C in carbon dioxide gas becomes incorporated into the sucrose molecules that are translocated in the phloem; Carbon dioxide is taken in by the leaves of the plant through small openings called stomata.

The CO₂ is fixed into organic molecules by the process of photosynthesis, which involves the conversion of CO₂ and water into glucose and oxygen.

The glucose molecules are converted into sucrose through a series of enzymatic reactions that take place in the cytoplasm of the leaf cells.

The sucrose is transported from the leaf cells into the phloem tissue, which is responsible for the translocation of organic molecules throughout the plant.

The 14C that was incorporated into the sucrose during photosynthesis is transported along with the sucrose through the phloem tissue.

As the plant uses the sucrose, the 14C is released and incorporated into other organic molecules in the plant's tissues.

The new X chromosome data support my hypothesis that the disease-causing mutation comes from a single base pairing change within the X chromosome.

In Chromosome the centro mere at this point functions to keep the double chromatin that make up each chromosome connected. Here, the centromere and the kinetochore, a protein structure linked to spindle fibers, are joined.

The chromosome also houses a significant portion of the proteins required for the production of the genetic code in addition to the genetic code itself. Its complex form and structure decide how frequently genes can be translated into proteins or which genes are translated.

The mechanism that leads to the development of living things is called gene expression.
