A change in genotype, but not in phenotype, is most likely due to neutral mutation.

A mutation consists of a spontaneous and unpredictable change in the sequence of genes that make up the DNA of a living being.

Therefore, we can conclude that a neutral mutation does not affect the viability of the living being.

Answer:

These fossils indicate that North America must have had a much warmer (i.e a tropical environment 370 million years ago)

Explanation:

Corals are marine animals whose skeletons are easily fossilized and thus have an extensive fossil record. There are many fossils of extinct corals in North America. For example, Lophophyllum is a North American extinct genus of corals dated at 320 million to 290 million years ago (i.e., from the Late Carboniferous period). In general, corals live in warm seawater, and thereby their fossil records can be used as indicators of environmental conditions.

Explanation:

Cells come from cells is correct  component of cell theory.

Theodor Schwann put forth the classical cell theory in 1839. This theory consists of three components.

All organisms are composed of cells, according to the first section. The basic building blocks of life are cells, according to the second section. The conclusions reached by Schwann and Matthias Schleiden in 1838 as a result of contrasting their observations of plant and animal cells served as the foundation for these sections.

Rudolf Virchow described the third element, which claims that cells originate from preexisting cells that have multiplied, in 1858 when he said omnis cellula e cellula (all cells come from cells).

Therefore, Cells come from cells is correct  component of cell theory.

Answer:

IF flowers are exposed to detergent, THEN the flowers will grow poorly

Explanation:

Hypothesis of an experiment gives a testable explanation to a problem. It is a predictive statement that explains the possible solution to a given problem, but subject to testing via experimentation. Hypothesis usually goes in an IF (cause), THEN (effect) format. That is, it shows how an independent variable will affect the deoendent variable.

In this experiment involving the effect of soap on flower growth, a possible hypothesis will be that: IF flowers are exposed to the detergent, THEN the flowers will grow poorly. This hypothesis, which is subject to testing by conducting an experiment, gives a possible solution to the problem of how detergent is affecting plant growth.

Answer:

Exponential growth occurs when the population is at its biotic potential, whereas logistic growth is limited by the carrying capacity of the environment.

Explanation:  

When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population's per capita growth rate decreases as population size increases. The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.

K is a constant that coincides with the size of the population at the equilibrium point when the natality rate and the mortality rate get qual to each other.

If the population size, N, is inferior to K (N<K) the population can still grow. When N approximates to K, the population´s growth speed decreases. When N=K, the population reaches equilibrium, and when N is superior to K (N>K) the population must decrease in size because there are not enough resources to maintain that size.  

The sigmoid curve represents the logistic growth model. At the beginning population grow slowly. In the exposed example this occurred when the small group of 10 foxes moved to the new environment, starting a new population. In the second stage, the population size increases rapidly. Probably this happened when foxes reached a number of 40 individuals. And finally, slow and gradually, the population reaches the equilibrium point, K, which depends on resource availability. This point belongs to the stage where food starts to become harder to find, and much of the living space is occupied.

This model is based on unlimited resource availability which means that there is no effect depending on density. There is no competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita and it is proportional to the population size.

Answer:

Altruism could be helpful for the survival of relatives

Explanation:

Altruism behavior is produced when an organism decreases its fitness in order to increase the chances of survival in other individuals in the population. It is believed that altruistic behavior could have evolved as an adaptation associated with the survival of relatives from the same family. In consequence, if this were the case, altruism could ultimately be considered as a selfish behavior because it aims at passing on of genes through the survival of relatives which could benefit with this behavior.

Answer:

The three types of symbiotic relationships are mutualism, parasitism, and commensalism. In mutualism, both organisms gain something, in parasitism, one organism gains and the other loses, and in commensalism, one gains and the other doesn't gain or lose

Answer: C.) 2L

Explanation:

Given the question :

A two-year-old weighing 25.2 lb is admitted to the hospital with fever and diarrhea. Normally the child weighs 29.6 lb. How much fluid (in liters) needs to be replaced in the child's system?

Normal body weight if the baby = 29.6lb (pounds)

Weight of baby die to fever and diarrhea = 25.2lb(pounds)

Weight loss due to diarrhea and fever :

(29.6 - 25.2)lb = 4.4 lb

Amount of fluid needed to be replaced in litres = weight loss due to sickness

Then we need to convert 4.4lbs to Litre (L)

1 pound (lb) = 0.45359 liter (l)

4.4 lb = (4.4 * 0.45359) L

= 1.995796 L

= 2L

cycling of molecules

Explanation:

In a cell, the flux of energy is associated to the cycling of molecules among subcellular compartments. In coupled reactions, the cycling of molecules between mitochondria and chloroplasts is required to produce the flow of energy and to sustain the life of the Earth. Chloroplasts produce chemical energy by using solar energy to convert water and carbon dioxide (CO2) into oxygen (O2) and high energy carbohydrates (i.e., sugars and starches). Subsequently, in the mitochondria, the process of cellular respiration enables to convert the carbohydrates into high energy molecules (ATP), releasing water and CO2.

Answer:

In order to lower the temperature.

Explanation:

Mammals and birds uses evaporative cooling due to their high body temperature because this evaporative cooling removes the high temperature from the body. In this process, the water present in the body absorb all the extra heat and remove this extra heat from the body with change its state from liquid to vapors and the body's temperature cools down. This evaporative cooling is occurs in the process of sweating.

Answer: Options are not given, here are the options.

a.Thylakoid membranes become more permeable to ions

b.The chlorophyll breaks down

c.The peripheral proteins lose their ability to bind to the transmembrane proteins

d.Water cannot bind to PSII to form oxygen

The correct option is C.

The peripheral proteins lose their ability to bind to the transmembrane proteins.

Explanation:

In photosystem 11, it is the center where light is converted to moving electrons. When the chlorophyll molecule absorb light, the electrons gain energy.

Increase temperature affects the activity of photosystem 11 because the peripheral protein lose their ability to bind to the transmembrane protein which is as a result of high temperature affecting the surface of ionic interactions which is for binding to transmembrane protein.

Answer:

1. 1.26823082 mL

2. 0.5 g/mL

Explanation:

The density formula is:[tex]d=\frac{m}{v}[/tex]

1.

Rearrange the density formula for v,

[tex]d=\frac{m}{v}[/tex]

[tex]d*v=\frac{m}{v}*v[/tex]                     Multiply both sides by v.

[tex]d*v=m[/tex]

[tex]\frac{d*v}{d} =\frac{m}{d}[/tex]                             Divide both sides by d.

[tex]v=\frac{m}{d}[/tex]

Volume is found by dividing mass by density. The mass is 20 grams and the density is 15.77 grams per milliliter.

[tex]m= 20 \ g\\d= 15.77 \ g/mL[/tex]

Substitute the values into the formula.

[tex]v=\frac{20 \ g} {15.77 \ g/mL}[/tex]

Divide. Note the grams, g, will cancel.

[tex]v= 1.26823082 \ mL[/tex]

2.

Use the density formula.

[tex]d=\frac{m}{v}[/tex]

Density is found by dividing mass by volume. The mass is 10 grams and the volume is 20 milliliters.

[tex]m= 10 \ g\\v= 20 \ mL[/tex]

Substitute the values into the formula.

[tex]d=\frac{10 \ g}{ 20 \ mL}[/tex]

Divide.

[tex]d= \frac{1}{2} \ g/mL[/tex]

[tex]d= 0.5 \ g/mL[/tex]

the thing you compare your experimental results to is called the control group.

Control group is the standard to which comparisons are made in an experiment. Many experiments are designed to include a control group and one or more experimental groups.

Moreover, some experiments use multiple control groups to gather more information and improve the accuracy of results. For example, many medical studies include positive, negative and placebo.

The control group and experimental group are compared against each other in an experiment. The only difference between the two groups is that the independent variable is changed in the experimental group.

Answer:

limiting factor

Explanation:

In an ecosystem, certain factors hinder the growth or abundance of the population of organisms. These factors are called LIMITING FACTORS. Limiting factors, which can be biotic, food, drought, predation, disease etc, are factors that inhibits a population of organism from becoming enlarged. There are two types of limiting factors viz: density dependent (depends on size) and density independent (not dependent on size).

This is the case of a drought that dries up the stream that inhabits a population of salamanders. The drought causes the unavailability of water, which will ultimately have an effect on the growth of the salamander population. Hence, the DROUGHT is considered a LIMITING FACTOR.
