A researcher discover two populations of birds that are similar. The two populations living habitats that are different. What evidence might suggest to the researcher that the birds belong to different species rather than the same species?

Answers

Answer 1

Answer: The two populations living habitats are different. Also they are only similar not the same. Although the physical features may look the same, the actual species may be totally different. :)

Protein can be found in both animals and vegetables.
a. True
b. False

Answers

Answer:

a. True

Explanation:

Proteins are biopolymers composed of amino acids that appear in chains. These amino acids are formed by peptide bonds. Due to the functions they carry out, proteins are essential for the existence of life. Proteins can be found in both animals and vegetables. In animals, there are proteins that help protect the body, others are in charge of regulating metabolism. On the other hand, in plants proteins participate in cell division processes, membrane transport, catalysis of biochemical reactions, photosynthesis and respiration processes, synthesis of sugars, starches, and other compounds.

True. Protein can be found in both animals and vegetables. Therefore, option (A) is correct.

All living species need amino acid-based proteins to shape, function, and regulate their cells and tissues. Meat, poultry, fish, eggs, and dairy are protein-rich. These sources often supply all needed amino acids.

Proteins in vegetables and plant-based diets differ from animal-based proteins. Plant-based protein sources include legumes, soy, nuts, seeds, and grains like quinoa and amaranth. A balanced amino acid profile can be achieved by eating a variety of plant-based proteins. Therefore, option (A) is correct.

Body composition has little to do with cardiorespiratory fitness. True or Faulse.

Answers

The answer is false. A number of additional factors effect cardiorespiratory fitness, but body composition is a big one. If you are inactive and 100 or more pounds overweight, your cardiorespiratory fitness will suffer greatly, especially compared to an active person with the proper body weight to their height and age.

the answer is false......................

Which would be a consequence of the removal of predators from a population such as the Trinidadian guppy population?a .The nitrogen excretion rate would increase.b. Guppy color patterns would change; guppies would produce fewer but larger offspring; the nitrogen excretion rate would increase and the rate of growth of primary producers such as algae would increase.c. Primary producers such as algae would overgrow.d. Guppies would produce fewer but larger offspring.e. Guppy color patterns would change.

Answers

Answer:

The correct answer is option b. "Guppy color patterns would change; guppies would produce fewer but larger offspring; the nitrogen excretion rate would increase and the rate of growth of primary producers such as algae would increase".

Explanation:

The Trinidadian guppy is a species of fish with the scientific name Poecilia reticulata. Just like almost all species, its population is regulated for multiple factors, one of them being the presence of predators. The removal of Trinidadian guppy predators would result in multiple consequences:

- Guppy color patterns would change. The fish have a complex coloration determined largely by predation avoidance.

- Guppies would produce fewer but larger offspring. This adaptation has been proved in an experiment at which the fish was introduced one a low predation environment. The report proved that evolution can take place in less than 10 years.

- The nitrogen excretion rate would increase. It has been reported that predation reduce Trinidadian guppy nitrogen excretion by 40%. Removing the predators will case the nitrogen excretion rate to increase due to an increase in the fish food intake.

- The rate of growth of primary producers such as algae would increase. This is an effect of the increase of nitrogen excretion rate, which benefits algae population to growth.

Which sentence is written correctly?Chicken a lean protein, can by prepared, in many healthy ways.

Lack of vitamin C in the diet interferes with the ability of fibroblasts to produce collagen. What effect might this interference have on connective tissue?

Answers

Answer:

Answer is given below:

Explanation:

Function of vitamin C is healing wounds. Its deficiency causes multiple effects on connective tissue. It decreases the amount of collagen synthesis and angiogenesis and increases the amount of fibroblast and also increases capillary fragility and definitely because of its deficiency wound will not be healed properly or may not be healed.
