A. The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.

Explanation:

got it right on edg quiz (see pic)

hope this helps :)

All nutrients that enter the circulation are processed by the digestive and excretory systems simultaneously, with the exception of oxygen, which is taken in by the respiratory system. The correct answer is a) The digestive system fuels the cells and the excretory system rids the body of the cells’ waste.

Nutritive substances are absorbed by the digestive system, and any that are not are expelled. By continuously purging the blood, the excretory system works in tandem to remove metabolic waste products from cells throughout the body.

The digestive system takes in the nutrients and water from the diet. All across the body, the circulatory system delivers nutrition, water, and oxygen to cells. The respiratory system, the excretory system, and the skin all remove waste from the cells.

The excretory system filters the bloodstream for nutrients and gathers unneeded components in your urine for disposal, whereas the digestive system absorbs nutrients, collects them, and then eliminates the undigested solids (feces).

Therefore, the correct answer is a).

The answer is D.All of the above

Answer:

D

Explanation:

1: Coral Bleaching happens when 2 to 3 degree temperature changes.

2: carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.

3: sea level rise happens when ice caps or glaciers melt.

4: it's all of them

Answer:

b. Usable nitrogen

Explanation:

Nitrogen is converted from atmospheric nitrogen (N2) into usable forms, such as NO2-, in a process known as fixation. The majority of nitrogen is fixed by bacteria, most of which are symbiotic with plants. Recently fixed ammonia is then converted to biologically useful forms by specialized bacteria.

Answer:

The instructions for making a pea plant are found in its genes. Each gene has the instructions for one small part of the pea plant. There is a gene that determines the color of the peas the plant will produce. These genes can come in all different versions.

Answer: The scientific names of species are italicized. The genus name is always capitalized and is written first; the specific epithet follows the genus name and is not capitalized. CAPITALIZING ORGANISM NAMES. Scientific Names. In the Latin scientific names of organisms, names at the species level and below (species, subspecies, variety) are not capitalized; those at the genus level and above (e.g., genus, tribe, subfamily, family, class, order, division, phylum) are capitalized.

Explanation:

Answer:

Reproduction, heredity, variation in fitness or organisms.

Explanation:

Evolution occurs in organisms due to natural selection process because natural resources are limited. Evolution is the change in the characteristics of a species over several generations. If evolution occurs in the organisms so these evoluted organisms can survive rate more than those organisms where no evolution occurs because the evoluted organisms can adopt successfully the features of environment. Reproduction, heredity, variation in fitness or organisms are the four factors needed for natural selection to act.

Answer:

Genetic diversity has decreased due to inbreeding due to dwindling population size.

Cheetahs are facing great pressures, such as climate change, destruction of their habitat, and also hunting by humans that have greatly impacted their genetic diversity.

Cheetahs have experienced a very declining rate of their populations due to destruction of their habitat, and also hunting by humans that has resulted in inbreeding in their populations and loss of genetic diversity.

Due to inbreeding, cheetahs have become more exposed to genetic disorders and vulnerable to diseases, and other threats.

Climate change has also posed a great threat to the declining population of cheetahs as it has affected their habitats and food resources. Climate change causes alteration in the temperature and rainfall pattern resulting in low availability of prey and water resources. Therefore, climate change leads to the malnutrition of cheetahs and making them more susceptible to severe disease.

Therefore, cheetahs are facing extinction due to climate change, habitat destruction, and hunting by humans.

Answer:

Miller and Urey's research showed that it was possible for organic molecules to be developed from inorganic molecules, which contributed to the hypotheses about the origin of the earth.

Explanation:

Stanley L. Miller and Harold C. Urey developed a series of research and experiments that showed that the planet earth, even in its primitive state, promoted a series of chemical reactions that used inorganic substances as a reagent, to create organic substances as a product and these organic compounds were the precursors of life on earth.

To reach this conclusion, they used a closed system, without the presence of oxygen, but with the presence of hydrogen, ammonia, methane and water vapor. They subjected this system to various cycles of electrical discharges, heating and condensation of the page, to create environments in which chemical reactions could happen. After some time, it was possible to observe the presence of organic molecules.

Answer:

Vas deferens → Male reproductive system

Fallopian tube → Female reproductive system.

Explanation:

In vertebrates, there are paired gonoducts for the movement of gametes from the gonads. Humans are no different.

1. Vas deferens is a male gonoduct that transports sperm away from the testes in preparation for ejaculation. Vas deferens collects secretion from seminal vesicle and becomes ejaculatory duct before draining in male urethra.

2. The fallopian tube is a female gonoduct that receives ova from the ovary when ovulation occurs. Fertilization occurs in the fallopian tube, and the early embryo moves from the tube to the uterine cavity.

3. Ciliated pseudostratified epithelium lines the vas deferens, while ciliated columnar epithelium lines the fallopian tube.

Answer: The desert animals do not get appreciable amount of water quantity to survive on daily basis instead their body mechanism tries to conserve water by concentrating urine.

Explanation:

The desert mammal like kangaroo rat produces hyper concentrated urine so as to conserve water. It is facilitated by extremely long loop of Henle in their nephron. The long loop of Henle increases the time and space for absorption of water and nutrients from the urine filtrate. Hence, urine so produced is more concentrate and conserve water. Moreover, the kangaroo rat consume their urine to survive in extreme hot desert condition in scarcity of water.

The concept of species is an important but difficult one in biology, and is sometimes referred to the "species problem".

Thus, Some major species concepts are, Typological (or Essentialist, Morphological, Phenetic) species concept. Typology is based on morphology/phenotype.

The biggest group of organisms that can generate fertile offspring, often through sexual reproduction, from any two individuals of the appropriate sexes or mating types is referred to as a species in biology. It is a unit of biodiversity as well as the fundamental classification and taxonomic rank of an organism.

A species can also be identified by its karyotype, DNA sequence, anatomy, behavior, or ecological niche. In addition, since fossil reproduction cannot be studied, paleontologists use the chronospecies idea.

There are between 8 and 8.7 million different species of eukaryotes, according to the most recent accurate estimate.

Thus, The concept of species is an important but difficult one in biology, and is sometimes referred to the "species problem".
