Explanation:

Fertility rates are an important factor to consider relative to population size because they directly affect the growth and size of a population over time.

Fertility refers to the ability of an individual, population, or species to produce offspring. It is the biological capacity of an organism to reproduce and is typically measured by the number of offspring produced per individual or per population over a given period of time. In humans, fertility is commonly measured as the number of live births per woman of childbearing age, typically between 15 and 49 years old. Factors that can affect fertility include age, health, nutrition, genetics, environmental factors, and access to healthcare. Understanding fertility is important for family planning, population growth projections, and reproductive health research and interventions.

The majority of the lizards who are still alive one year after cats were allowed to roam free with them should be little.

The characteristic of having longer horns is advantageous for survival and will probably grow more prevalent in the population over time as the short-horned lizards die off. Longer horned lizards have a higher chance of surviving than shorter horned lizards do.

Reproduction, inheritance, variation in organism fitness, and variation in individual attributes across population members are the four conditions necessary for natural selection to occur. Whenever they are satisfied, natural selection takes place on its own.

Question:-

A year after cats were let loose with the lizards, most of the surviving lizards should be which of the following?

The mechanism of natural selection works like this:

Within a population of a particular species, there is genetic variation, meaning that individuals within that population differ from one another in terms of their genetic makeup. Some of these variations may be advantageous, such as the ability to blend and be more fitted in with the environment in order to survive, while others may be disadvantageous.

Natural selection is a process that explains how certain genetic traits become more or less common within a population over time. It is one of the key mechanisms of evolution.

Individuals with advantageous variations, like camouflage in this case, are better suited to survive in their environment because they are harder for predators to detect. As a result, these individuals are more likely to reproduce and this trait of advantage can be inherited by their offspring

Generally, The rate of breathing increases by decrease in oxygen or increase in carbon dioxide levels in the blood.

Answer: performing physical activities such as exercice,running etc.

Explanation:

Answer:

Photosynthesis is a process used by plants, algae, and some bacteria to convert sunlight into chemical energy. This energy is stored in the form of sugars, which can then be used by the organism for growth and development. During photosynthesis, light energy is absorbed by chlorophyll molecules and converted into chemical energy, which is then used to produce sugars from carbon dioxide and water. Oxygen is also produced as a by-product of the reaction.

The dilution factor for Bottle B is 100, and 0.01 can be expressed as 10^-2, which represents a fraction of 1 that is smaller than 1.

To determine the dilution factor for Bottle B, we need to calculate the ratio of the amount of the original sample to the final volume after dilution.

In this case, the original sample is 1 ml, and the final volume after dilution is 99 ml. Therefore, the dilution factor for Bottle B is 99/1, which equals 10^2 or 100.

To express 0.01 as a power of ten, we need to determine the exponent that represents the number 10 when raised to that power, which will result in 0.01 as the value. In this case, 0.01 can be written as 10^-2.

This means that 10 raised to the power of -2 is equal to 0.01. The negative sign in the exponent indicates that the value is less than 1, as it represents a fraction of 1 that is smaller than 1.

Exothermic: A reaction releases 180 J, The combustion of wood provides energy.

Endothermic: The energy level of the reactants is lower than that of the products.

An endothermic reaction is a chemical reaction in which energy is absorbed from the surroundings in the form of heat. In other words, the reaction requires energy input to occur and the surroundings cool down as the reaction takes place.

Endothermic reactions can be identified by a decrease in temperature during the reaction. This is because the energy absorbed from the surroundings is used to break bonds in the reactants and create new bonds in the products. The energy required to break these bonds is greater than the energy released when new bonds are formed, so the overall energy change is positive.

Sarcomere, a repeating myofibril unit. Sarcomeres are simply repeating units, or polymers, called myofibrils.

Muscle contractions result from the individual muscle fibers contracting as a result of the individual sarcomeres shortening.

A, C, D, E, and F are all processes that can cause changes in allele or genotype frequencies in populations. Mutations (A), Gene Flow (B), Genetic Drift (C), Non-Random Mating (D), and Natural Selection (F) all have the ability to change allele frequencies over time.

Allele frequency changes over time in a population as a result of the following processes: Mutation is the first process. Mutations can cause new alleles to appear or cause existing alleles to become more or less frequent.

Gene flow is the second process. When individuals migrate and mate in a population, new alleles may be introduced or removed, causing changes in allele frequencies.

Genetic drift is the third process. Random events in a small population may result in some alleles becoming more frequent while others become less frequent. This is known as genetic drift. Nonrandom mating is the fourth process.

If mating is random, allele frequencies in the population remain stable over time. Natural selection is the final process. Certain alleles may provide a survival or reproductive advantage, causing them to become more frequent in the population over time. Therefore the correct option is option A, B, C, D and F.

Protons are actively transferred from the mitochondrial matrix into the intermembrane gap as electrons move along the electron transport chains. Option 4 is Correct.

One of the changes that takes place as electrons move along mitochondria's electron transport chains is a rise in the matrix's pH. Both photosynthesis and cellular respiration take place in mitochondria. In the former, energy is released together with the release of electrons from the breakdown of organic molecules.

In the latter, after being activated by light, the electrons join the chain, and the energy released is utilized to create carbs.
