True or false: Theoretically, it is possible (but very difficult) for a population to not evolve for a while.

Answers

It is true that it is possible for a population to not evolve for a while.

There is something called the Hardy-Weinberg theorem, which characterizes the distributions of genotype frequencies in populations that are not evolving.

There are 5 Hardy-Weinberg assumptions:

no mutation random mating no gene flow infinite population size and no selection (natural nor forced).

You can see that some of these are kinda extreme and really hard to get, but with approximations, we can work.

For example, instead of an "infinite population size" we have enough with a really large population, such that genetic drift is negligible.

Concluding, yes, it is possible (but really difficult) for a population to not evolve for a while (at least, in nature), as long as the 5 assumptions above are met.

biodiversity of plant and animal species

Answers

Answer:

D

Explanation:

As population grows all the above factors increase expect the biodiversity of animal and plant species.

On a basic level, it is obvious that population increase and per capita income growth are related. Per capita income is simply total income divided by the population.  Thus, option D is correct.

What inverse relationship to population growth?

When attempting to forecast changes in population size, demographers frequently focus on four essential criteria.

The population's starting age profile (whether it is relatively young or old to begin with), migration, and fertility rates (death rates; life expectancy).

Depending on particular environmental factors, two different patterns of population expansion may manifest: In a perfect, limitless environment, an exponential growth pattern (J curve) manifests itself.

The development of a logistic growth pattern (S curve) occurs when external forces reduce the pace of growth.

Therefore, The gap between the growth rates of income and population is roughly equivalent to the growth rate of per capita income.

The part of the diencephalon that is in the anterior and inferior region of the diencephalon is the Hypothalamus.

What is Hypothalamus?

The hypothalamus exists a portion of the brain that includes a numeral of small nuclei with a combination of functions. One of the most important operations of the hypothalamus exists to link the nervous system to the endocrine system via the pituitary gland. The hypothalamus exists discovered below the thalamus and exists as part of the limbic system. The terminology of neuroanatomy, includes the ventral part of the diencephalon. All vertebrate brains include a hypothalamus. In humans, it stands the size of an almond.

The hypothalamus stands answerable for the regulation of specific metabolic functions and other actions of the autonomic nervous system. It synthesizes and secretes certain neurohormones, named releasing hormones or hypothalamic hormones, and these, in turn, promote or inhibit the secretion of hormones from the pituitary gland. The hypothalamus influences body temperature, hunger, important aspects of parenting and affection manners, thirst, fatigue, sleep, and circadian rhythms.

Hence, The part of the diencephalon that is in the anterior and inferior region of the diencephalon is the Hypothalamus.

Answer:

Option 4. an insertion mutation in an egg cell that deactivates a gene for hair color, resulting in a viable error.

Explanation:

Only germline mutations are hereditary in nature i.e., that can be passed on from the parent to the offspring. Examples of hereditary mutation include Sickle cell anemia or hemophilia.Germline mutation: Any noticeable genetic changes in the germ cells of the body that is passed on from the parent to off spring.Mutations such as somatic cell mutation, chromosomal mutation, silent mutations are not hereditary.Option 4 talks about the mutation in egg cells i.e., the reproductive cell which affects the phenotypic traits such as hair color. The change in the phenotypic trait means that it is a genetic mutation of the egg cell as phenotypic changes only occur as a result of genetic mutation. Hence, any detectible mutation in the germ cell can pass on from a parent to offspring.

In the morning, a 160-pound college student consumes a bowl of cereal with 750 calories. 30 minutes of running can only burn 200-500 calories.

What is Calories?The calorie is a type of energy unit. For historical reasons, there are two main definitions of "calorie." The large calorie, food calorie, or kilogram calorie was originally defined as the amount of heat needed to raise the temperature of one kilogram of water by one degree Celsius.Calories are the units of energy released by your body when it digests and absorbs food. The higher the calorie content of a food, the more energy it can provide to your body. When you consume more calories than you require, your body stores the excess calories as fat. Even fat-free foods can be high in calories.

The ancestors of modern-day fish were vertebrate chordates. Vertebrate chordates are believed to have evolved from invertebrate chordates, which were similar to modern-day tunicates.

B.
An endoskeleton evolved to enclose the spinal cord, which develops from the notochord.
C.

D.
A backbone evolved to enclose the spinal cord, which develops from the dorsal nerve cord.

Answers

Answer:  

The correct answer is option B, that is, an endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.

Explanation:

It has been discovered that the ancestors of the modern-day fish were vertebrate chordates. The vertebrate chordates are considered to have evolved from the invertebrate chordates that are identical to the present day tunicates. It has been found that in vertebrates the endoskeleton has evolved to encompass the dorsal nerve cord that has been developed from the notochord (a characteristic of invertebrates).

C. An endoskeleton evolved to enclose the dorsal nerve cord, which develops from the notochord.

Which of the following sentences state a significant conclusion that Gregor Mendel drew from his experiments with pea plants? Traits are inherited in discrete units and are not the result of "blending." Genes are composed of DNA. Recessive genes occur more frequently in the F1 generation than do dominant ones. There is considerable genetic variation in garden peas.

Answers

Mendel concluded that the alternative forms of each trait are coded by discrete factors, which were called alleles that combine in pairs to express the trait. Traits are inherited in discrete units and are not the result of "blending."

------------------------

After making many crosses that involved different traits -such as plant height, or flower colors-, Mendel observed that, per trait, the F1 only expressed one of the alternative forms, while de other one disappeared.

Mendel named dominant the expressed variant.

Mendel then let these new plants auto pollinate and observed the results in the second generation, F2.

He saw that the variants that had previously disappeared among the F1, reappeared again. Both alternatives for each trait were present in the F2.

Mendel named recessive the second alternative variant.

Mendel explained his results by arguing that discrete factors were responsible for these phenotypes.

These factors should have been present in the F1 in pairs.

One of them came from one parental plant, and the other factor came from the other plant.

These factors separated again during sex cells formation, producing two types of gametes, each with only one factor.

Mendel conclusion about his experiments was that per trait -flower color of plant length-, each plant had a pair of factors -which he named alleles-, and that each factor coded for one of the alternative forms of the traits -white or purple, tall or short-.

He thought that alleles separate -segregate- during the process of gamete formation.

The First Mendel's Law is the first conclusion he took about his experiments and is known as the segregation principle.
