These plants lack flowers and seeds. Which of the following is described by this statement? Angiosperms Ferns and horsetails Gymnosperms

Angiosperms are literally known as "flowering plants" and include all the flowering plants. Gymnosperms are seed-producing plants, such as trees that don't have flowers. So that leaves you with ferns and horsetails. Ferns have spores on them that they use to reproduce with, and they do not have flowers.

Which statement explains the difference between multiple alleles and polygenic inheritance? A) Multiple allele means more than one gene contributes to the phenotype and polygenic inheritance means more than two forms of the same gene in the population. B) Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait. C)Multiple allele means more than two forms of different genes in the population and polygenic inheritance means one gene contributes to many phenotypic characters.

 The answer is B) Multiple allele means more than two forms of the same gene in the population and polygenic inheritance means more than one gene contributes to the phenotype of a trait.

An allele is one of two or more alternative forms of a gene. So, multiple allele means more than two forms of the same gene in the population. 
Polygenic inheritance is responsible for traits that are controlled by two or more genes. The name itself explains the meaning: poly means many, so literally it means many genes.

Answer;

  • radiometric dating of rocks
  • fossil evidence
  • gradual processes of rock

Explanation;

Radiometric dating confirms that Earth is ancient and explains how extremely slow processes can result in major changes to Earth’s surface. Evidence from radiometric dating indicates that Earth is about 4.54 billion years old. The geology or deep time of Earth's past has been organized into various units according to events which took place.

-The ages of Earth, Moon, and meteorites, radiometric dating has been used to determine ages of fossils, including early man, timing of glaciations, ages of mineral deposits, recurrence rates of earthquakes and volcanic eruptions, the history of reversals of Earth's magnetic field, and the age and duration of a wide variety of other geological events and processes.

Which of the following describes the properties that allow capillaries to exchange gas between blood cells and surrounding tissue? a. Capillaries are short vessels with thin walls that create strong pressures forcing gas-infused blood to diffuse to the surrounding tissue. b. Capillaries have thin walls and narrow diameters so that blood cells come close to the thin walls, across which gases can diffuse to surrounding tissue. c. Capillaries have valves along their walls that allow blood cells to move through them to surrounding tissue, where gas exchange can occur. d. Capillaries regulate the pressure of blood within them so that a steady stream of gas-infused blood cells passes into the surrounding tissue.

The answer is b. Capillaries have thin walls and narrow diameters so that blood cells come close to the thin walls, across which gases can diffuse to surrounding tissue.

Capillaries are the smallest of all blood vessels. They have very narrow diameters (5-10 micrometers) and thin walls. All of this allow the blood cells to come close to the walls and cross them so gases diffusion to surrounding tissue can occur.

Through the process of elimination:
- a. is not the right choice because thin walls could not persist strong pressure.
- c. is not the right choice because capillaries do not have valves like veins do.
- d. is not the right choice because capillaries are that small they cannot regulate the blood pressure within them.

How is nitrogen returned to the atmosphere during the nitrogen cycle? a. It is returned to the atmosphere in a process called nitrogen fixation. b. It is returned to the atmosphere through denitrification. c. It is returned to the atmosphere through cellular respiration. d. It is returned to the atmosphere through evapotranspiration.

  • Nitrogen is returned to the atmosphere during the nitrogen cycle through denitrification.
  • The nitrogen cycle is a cyclic process in which the atmospheric nitrogen is converted into a form that can be utilized by the living organism and then it is returned back to the atmosphere so that the cycle can continue.
  • The process that is responsible for returning it back is denitrification in which the nitrate (NO3-) is converted back to nitrogen (N2) with the help of denitrifying bacteria who utilize nitrate to gain oxygen and in this process, the free nitrogen is liberated which returns back into the atmosphere.

Its not actually just one system if you look at it, there are various interdependent system that actually manages every movement of every system in order to maintain homeostasis, plainly every set function is a coordinated body system response. For example, the digestive system digests food because of the enzymes and the cells and organs present in its system but again, this is aided by the different hormones which is part of the endocrine system, interdependently. Thus eventually, the circulatory system is the organ system that intiates in dissemination of the different processed and intially metabolized nutrients in the digestive system and sent throughout the body. Incidentally, also the immune system acts as agent in again many systems to maintain the so-called homeostasis.

Jenna says that an example of homeostasis is when body temperature is maintained at about 37° C. Allen says homeostasis is when breathing rate increases along with exercise. Who is correct? A. Only Allen is correct. B. Both are correct. C. Only Jenna is correct. D. Neither is correct.

B. Both are correct

Both are correct is the accurate answer. Why? Because as Jenny said our body maintains our temperature at approximately 37C which is the conditional temperature where our cells could do significant and existential processes. Also is maintained by the hypothalamus. Moreover, when we exercise, the amount of oxygen decreases thus muscles around the thoracic region increase the breathing rate.
