Many desert mammals have developed a nocturnal lifestyle. This means that during the day they sleep underground in their burrows, and they come out to eat and play at night. What is a good reason for a desert fox to show this pattern of behavior?

Answers

Answer:

A good reason why a desert fox shows this pattern of behavior is to protect themselves from cold conditions since at nighttime, it gets very cold in the desert!

Explanation:

Nocturnal is a type of animal behaviour shown when the animals are active at night time and inactive at daytime. Desert fox shows this behaviour so that it can avoid the hot daytime of the desert.

What is nocturnal behaviour?

Nocturnal lifestyle is the behaviour adopted by animals that are active at night time and are inactive during the daytime. During the daytime, they rest in the cool burrows, holes and underground canals to prevent the loss of water and to protect themselves from the extremely hot environment.

The desert animals like desert foxes have adapted the nocturnal lifestyle to avoid the extreme heat during the daytime and sleep in their underground burrows. Instead, they come out during the night when it is cool in deserts to eat and play.

Nocturnal lifestyle is shown by the diurnal animals that rest and sleeps in the burrows, holes and cool places during the hot time of the day.

Therefore, the desert fox shows a nocturnal lifestyle.

Select an organism of your interest! Research to see if that organism undergoes asexual or sexual reproduction. Describe why that type of reproduction is advantageous for your organism.

Answers

Answer:

Many fungi and plants reproduce asexually. Some plants have specialized structures for reproduction via fragmentation.

Explanation:

This allows them to adjust to conditions in the environment. They can spread quickly through asexual reproduction when conditions are stable. They can increase their genetic variation through sexual reproduction when conditions are changing and variation may help them survive.

Reproduction is a method by which the genetic material from the parent is transferred to offspring and in this way the character and traits are passed from generations.

I will select plants for my research purpose.

Plants are species that reproduce sexually. They have male and female organs that produce cells for reproductions. They sexually reproduce through the process of pollination.

This method of reproduction helps in genetic variation and in forming recombinant species that are more variant.

This variation helps the plant species to survive better compared to less competent species.

Sexual reproduction is beneficial for plants as it increases varieties and helps plants in fighting against a common population disease.

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPa, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl

Answers

Answer: hello your question is in complete  below is the complete question

A fiber reinforced composite contains e-glass fibers in an epoxy matrix. E for the glass is 72 GPA, E for the epoxy is 2.4 GPa. Find the elastic modulus of a composite that contains 5% fibers in the longitudinal direction, Ecl = ViEi + EmVm? (note Vi + Vm= 1.) O 5.88 GPa O 5.66 GPa O 2.52 GPa O 6.74 GPa

answer : 5.88 GPa

Explanation:

Fiber reinforced composite containing e-glass fibers

E for the glass ( Ei ) = 72 GPa

E for the epoxy ( Em ) = 2.4 GPa

Determine the Elastic modulus of a composite containing 5% fibers

percentage of glass = 5% = Vi = 0.05

∴ percentage of epoxy = 95% ; Vm = 0.95

using the relation included in the question

Ecl = Ei Vi + Em Vm

    = ( 72 * 0.05 ) + ( 2.4 * 0.95 )

    =  3.6 + 2.28  = 5.88 GPa

The amphibian heart has a single, undivided ventricle, two atria, a sinus venosus, and a Conus arteriosus. Their sarcopterygian ancestors had hearts with all of these chambers, but the ventricle was partially divided and probably aided in separating pulmonary and systemic circulatory circuits. Check the following statements that could help us understand why amphibian evolution resulted in the loss of the partial ventricular septum.
A .The loss of the ventricular septum probably occurred because blood returning to the heart of amphibians bypasses the ventricle being shunted from the sinus venasus and right atrium directly to the pulmonary artery and lungs.
B. Loss of the partial ventricular septum reflects the fact that blood returning to the heart from the systemic circuit is often highly oxygenated because many amphibians rely on cutaneous and buccal gas exchange, as well as pulmonary gas exchange, much of the time.
C. Mixing of blood from the lungs with blood from the body in the ventricle is not a problem. Loss of the partial ventricular septum is not a problem because the spiral valve keeps systemic and pulmonary blood separate within the ventricle.
D. The Conus arteriosus of the amphibian heart receives blood from the right atrium and passes the blood on to the pulmonary circulation. This keeps oxygenated and nonoxygenated blood separate.
E. The slightly asynchronous contraction of left and right atria help keep systemic and pulmonary circuit blood separated in the ventricle.

Answers

Answer:

D. The Conus arteriosus of the amphibian heart receives blood from the right atrium and passes the blood on to the pulmonary circulation. This keeps oxygenated and nonoxygenated blood separate.

Explanation:

The conus arteriosus plays an important role in directing blood into the correct arterial arches in amphibian which keeps oxygenated and nonoxygenated blood separate from one another. The Conus arteriosus of the amphibian heart receives blood from the right atrium chamber of heart and passes the blood on to the pulmonary circulation which keeps oxygenated and nonoxygenated blood separate from each other and there is no need for partial ventricular septum.

They are easily removed from the air when people see them floating.
They are constantly filtered by the nose, which prevents lung absorption

Answers

Answer:

B

Explanation:

The role the ultrafine particles play in dirty air is that they can worsen symptoms for people with breathing difficulties. The correct answer is b).

What are ultrafine particles?

The term "ultrafine particles" (UFPs) refers to particles with a dimension of less than micrometers and more than 0.1 micrometres (100 nanometers), also known as nanoscale particles. The majority of the ultrafine particles are found on motorways and are mostly produced by vehicle emissions.  

It has been demonstrated that ultrafine pollution particles may play a crucial role in igniting extra pathways or inflammation, which worsens asthma disease. The ultrafine particles released by motor vehicles and other sources of combustion are covered with an organic chemical coating that can be inhaled.

By oxidizing cells and tissues, these substances create free oxygen radicals that activate the immune system in the lung. For those who have asthma, oxidation exacerbates the allergic inflammation in their lungs.  

Therefore the correct option is b).

APC is a tumor suppressor and acts in the Wnt signaling pathway to prevent the TCF complex from turning on Wnt-responsive genes. Mice that lack the gene encoding TCF4 do not have the ability to maintain the pool of proliferating gut stem cells needed to renew the gut lining. What do you predict will happen in mice that lack the APC gene

Answers

Answer:

As APC is indicated as a tumor suppressor, lack of APC would lead to tumor development in the mutated mice.

Explanation:

The wnt signaling pathway plays an important role in controlling stem cell proliferation. Stem cells are present in the gut and other locations where they are required to be replenished after short intervals. In the gut, the gut epithelial is exposed to a very tough environment i.e. digestive acids. Thus it is replenished where the new stem cells originate from underlying stem cells.

Axin binding is the major component of this process. However, the unaffected axin leads to binding with a component termed TCF. TCF4 genes include cell cycle factors (such as myc) that encourage cell regeneration.

When the ligand is absent and APC is present, the axin bound with APC to form a team that directs and controls the cell regeneration.

Thus, if APC is not expressed in a cell, beta-catenin in the axin is available to bind to TCF inducing wnt response element genes that stimulate cell proliferation.

The result in tissue level is an enhanced rate of cell growth which leads to tumor.  

The rest of the group agrees with your conclusion that Dr. Tamm was likely exposed to a membrane uncoupling agent. Uncoupling agents allow protons to cross the inner membrane of the mitochondria, down their concentration gradient, without passing through ATP synthase. Consider that each respiring cell has a need for a certain amount of ATP, but in the presence of a membrane uncoupling agent, the proton gradient that is generated by the ETC is being partially dissipated without any ATP being made. How do you think the activity of other metabolic pathways might change in response

Answers

Answer:

No more reactions occurs.

Explanation:

The activity of other metabolic pathways also change in response to the proton which enters mitochondria without passing through ATP synthase because ATP synthase is responsible for the production of ATP molecules from proton. If this ATP is not produced no further reactions occurs in the cell. This ATP is used by the cells in various activities so if the proton does not pass through ATP synthase then no energy in the form of ATP is present for other metabolic pathways of the cells.
