In the autumn, many birds will collect seeds and then hide them in various caches throughout their habitat. The birds will guard their caches from other birds, and move the caches if they start to dry out. These caches provide a food source for the birds during the winter. What is an abiotic factor that contributed to the evolution of this set of behaviors? A. being preyed upon by larger birds B. competition with other birds for space C. limited food availability D. cold winter climate

Answers

Answer 1

Answer:cold winter climate

Explanation:During winter specially in the eastern and western part of the world....snows bury grounds and food that enables this organisms live....and cold can also affect them

Answer 2

Answer:

Answer: c. limited food availability

Explanation:

Both biotic and abiotic factors are responsible for shaping the evolutionary framework of the population. Resource availability can be one of the important abiotic  factor in determining the evolutionary dynamics of the population or species. Limitations in resource can result in increase in competition.  According to population exclusion principle when two species compete for the same limiting  resource this results in co-evolution of both the species. But the extent of evolution may vary among the species. The one which undergoes more favorable evolution will be stronger competitor and drive more resources and will be fit for survival in adverse limiting conditions.

Describe how the chemical bonds in unsaturated fatty acids make them more suited for cell
membranes than saturated fatty acids.

Answers

Answer:

Unsaturated fat, a fatty acid in which the hydrocarbon molecules have two carbons that share double or triple bond(s) and are therefore not completely saturated with hydrogen atoms. Due to the decreased saturation with hydrogen bonds, the structures are weaker and are, therefore, typically liquid (oil) at room temperature .

Explanation:

Genetics is a discipline that studies the transmission of heritable traits from parents to offspring. Population genetics is a discipline that analyzes genetic and allele frequencies in natural populations, as well as their changes in evolutionary processes. Finally, molecular genetics is a research field that studies the structure of the DNA molecule, its replication and the development of genetic engineering technologies associated with the manipulation of genetic information.

a. Hereditary genetics = 1 and 2

b. Population genetics = 3  

c. Molecular genetics = 4 and 5

The following information should be considered;

Genetics refers to a discipline that studies the conversion of heritable traits from parents to offspring. Population gen-etics should be the discipline that analyzes genetic and all-ele frequencies in a natural populations along with it their changes in evolutionary processes.

ANP is a hormone that causes:_________ a. constriction of the afferent arterioles and inhibition of renin release. b. dilation of the afferent arterioles and inhibition of renin release. c. dilation of the afferent arterioles and release of renin. d. constriction of the afferent arterioles and release of renin.

Answers

Answer:

b. dilation of the afferent arterioles and inhibition of renin release.

Explanation:

Atrial Natiuretic Peptide is a hormone which is mainly made and secreted in the atria. It helps in the regulation of blood pressure levels with the use of the kidney through an increase in water and sodium excretion.

The hormone helps in the regulation of blood pressure by ensuring there are dilation of the afferent arterioles to give room for increased flow of blood due to the increased pressure. Study also shows that the enzyme inhibits the release of renin.

What molecule is required each time the myosin head detaaches from one site and reattaches to another

Answers

Answer:

The adenosine triphosphate (ATP) molecule

Explanation:

The actin filaments are often associated with myosin to produce muscle contraction. These myosin filaments are considered to be 'molecular motors' capable of converting the chemical energy contained in the ATP molecule to mechanical energy, thereby producing cell movement. Myosin heads bind to actin filaments in order to generate a power stroke. When the adenosine triphosphate (ATP) molecule binds to myosin, the myosin head detaches to the actin filament. During this process, the ATP molecule is broken down and then the released energy is used by the myosin filament to return to its original position.

(05.05 MC) Exposing human subjects to experimental manipulations such as high levels of toxins is unethical. We often use model organisms for this reason. What attributes would you look for in selecting a good model organism for investigating the impact of toxins in humans? A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible. Cost is the only consideration in selecting a model organism, since all living things are made of cells anything found will apply to humans. The best choice will must be the very closely related to humans, such as chimps, since anything found in other species will not apply to humans. The most important consideration in selecting a model organism is how the public will feel about doing experiments on that species, so the best choice would generally be a very simple organism like bacteria that people don't care very much about.

Answers

Answer:

A good model organism should be able to be easily maintain in the laboratory, be fast growing, with a fast generation time and be as closely related to humans as possible.

Explanation:

The attributes that should be looked for in the selection of good model organism for investigating the impact of toxins in humans include:

Easy maintenance: The easier the maintenance of the organism, the better for both the research and the researcher. More can be achieved with less effort as opposed to high maintenance animals.Fast generation time: They should be able to grow and reproduce quickly so as not to prolong the experiment for too long. The lower the regeneration time, the shorter the time required to obtain adequate data for the research.Genetical similarity to humans: A good model organism for humans related study must share some similarities with humans at the genetic level. The more the genetic similarity, the more applicable the outcome of the research on humans.

Hence, a good model organism should be able to be easily maintained in the laboratory, be fast-growing with a fast generation time, and be as closely related to humans as possible.

Why is the communication results circle linked to the circle labeled science and society

Answers

Answer:

Because these circles have three factors that are directly interconnected.

Explanation:

As you know, communication is one of the primary factors for the creation and maintenance of societies. Societies grow and develop with communication as a starting point and a link between people and the actions that a society lives.

Science, in turn, is also directly influential in the creation and development of society, since it is a transforming factor that shapes society through its constant evolution.

As science evolves, society changes and communication must accompany these changes, so that both society and science continue to exist.

For this reason, we can say that the circle of communication results is linked to the circle called science and society, because these factors are directly interconnected.
