Answer:

D. anaerobic autotroph

Explanation:

Answer:

Transpiration is the process of evaporation of water from the leaves and stems to the atmosphere. The stomata close when the guard cells shrink, which in turn ceases the transpiration. Opening of stomata allows the process of transpiration, so the root cells do not die.

But if it can't close:

The downside to wide open stomata is increased water loss (transpiration). So stomata of cool-season turf grasses have decisions to make. The plant needs to capture and store energy via photosynthesis, however, excessive water loss through transpiration can result in plant injury or death.

It's a bad thing.

Answer:

A dorsal root (sensory or afferent) and a ventral root (motor or efferent) originate from the medulla. They unite near the intervertebral foramen, forming the spinal nerve. The nerves emerge from the intervertebral foramen, dividing into ventral and dorsal ramus.

Explanation:

The nerve is a set of nerve fibers perceptible to the naked eye and wrapped in connective tissue. They are made up of roots, trunks and nerve branches (some of them come together and form plexuses).The spinal nerve originate from the spinal cord in the form of 31 pairs: 8 cervical, 12 thoracic, 5 lumbar, 5 sacral and 1 coccygeal. They emerge from the spinal cord through two roots: dorsal roots, made up of sensory fibers that come from the sensory neurons of the spinal ganglion and that penetrate the spinal cord through the posterolateral  and ventral root, made up of motor fibers, coming from the motor neurons of the anterior horn and visceral of the lateral horn of the gray matter of the spinal cord. This root exits the spinal cord through the anterolateral groove, then joins the posterior root to form the spinal nerve, which exits the vertebral canal through the corresponding intervertebral foramen.Each spinal nerve, after leaving the vertebral canal, emits two primary ramus: the dorsal ramus, contains somatic and visceral fibers that go to the skin and muscles of the back and the ventral ramus, which supplies the ventrolateral surface of the skin, body wall and extremities.

Explanation:

Answer: Black allele has frequency of 0.14.

              Red allele has frequency of 0.86.

             The frequency of heterozygotes is 0.241

Explanation: Hardy-Weinberg model states the frequency of alleles in a population will stay in equilibrium as long as there are external influences. It is also used to determine alleles frequencies using the following equations:

[tex]p+q=1[/tex]

[tex]p^{2}+2pq+q^{2}=1[/tex]

p represents frequency of dominant allele;

q represents frequency of recessive allele;

2pq is frequency of heterozygotes;

For the frequency of red allele, which is dominant, we can use:

[tex]p^{2}=\frac{37}{13+37}[/tex]

[tex]p^{2}=\frac{37}{50}[/tex]

[tex]p^{2}=0.74[/tex]

[tex]p=\sqrt{0.74}[/tex]

p = 0.86

For the black allele:

[tex]p+q=1[/tex]

[tex]q=1-p[/tex]

[tex]q=1-0.86[/tex]

q = 0.14

Frequency of heterozygotes is

2pq = 2(0.86)(0.14)

2pq = 0.241

Frequencies for a population of Muscovy ducks are 0.86 for red allele, 0.14 for black allele and 0.241 for heterozygote.

The correct pathway that the food travels during digestion is Mouth, esophagus, stomach, small intestine, large intestine. The correct option is D.

The gastrointestinal tract (also called the digestive tract). This long tube of organs serves as a conduit for food to pass through the body. It includes the esophagus, stomach, and intestines and runs from the mouth to the anus (where poop comes out).

The digestive system's alimentary tract is made up of the mouth, pharynx, esophagus, stomach, small as well as large intestines, and rectum.

The alimentary tract's primary function is to convert food into absorbable particles and transport them to the body's other organs.

The correct digestive pathway is the mouth, esophagus, stomach, small intestine, and large intestine.

Thus, the correct option is D.

Explanation:

Because 1,000 divided by 100 equals 10.

There is a population of 1,000 wolves. Over the course of a year, 100 wolves are born. The birth rate is 10 births per individual per year. The correct option is b

Birth rates of organisms decline and mortality rates increase in density-dependent populations due to numerous factors affecting the rate of reproduction and survival.

When there is a disease, competition, or predation in that organism, it has a higher mortality rate and a lower growth rate. These three factors reduce the birth rate and raise the death rate in an organism's population.

If both the death and birth rates are low, the population will not grow significantly and will remain relatively stable.

1000 / 100 = 10

Therefore, the correct option is b, 10 births per individual per year.

Answer:

the answer is C6H12o6

Explanation:

Answer:

The quote refrences to the fragility of our enviorment and how that balance is to not be disrupted. That no matter how small,every detail affects that balance and is not to be tampered with. It is the same in the food chain,the elimination of even the smallest of species can have devastating effects on an ecosystem. That is why it is important to preserve resources and respect all life. an example of that balance being disrespected in the movie would be the scene where the once beautiful valley was barren and dry due to the hyenas destroying and using up all of the resources, thus destroying the balance of life and bringing famine to their lands.

Explanation: The circle of life man

When a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

This quote is related to the concept of the food web, pyramid of energy, and the pyramid of numbers because every organism is dependent on other organism for its survival. If that organism is eliminated from the ecosystem, then the organism that feeds on it also die.

If this balance is not respected and maintained then the whole ecosystem is destroyed because every organism is dependent on othe organism.

So we can conclude that when a balance is not respected then it leads to destruction of the whole ecosystem not a single organism.

The correct answer is protection because the integumentary system provides protection.

The skin and other parts of the integumentary system work in concert with other organ systems to maintain homeostasis. The skin works with the immune system to protect the body from pathogens by acting as a physical barrier to microorganisms.

Description: This feature is usually called the exoskeleton because it can be the hair of the nail, or basically the inner one that grows naturally on the outside, but in this case, it is not the exoskeleton, It is there to protect.

The skin has three main functions: protection, regulation, and sensation.

Thus it concludes that the integumentary system has the ability to provide protection.

Nuclear fusion is the process by which two or more atomic nuclei join together, or “fuse,” to form a single heavier nucleus. During this process, matter is not conserved because some of the mass of the fusing nuclei is converted to energy, which is released. Fusion is the process that powers active stars, releasing large quantities of energy.

Answer:

Sea urchins use five-part jawlike structures to scrape algae from rocks. Sea lilies use tube feet along their arms to capture floating plankton. Sea cucumbers move like bulldozers across the ocean floor, taking in sand and detritus. Sea stars usually feed on mollusks such as clams and mussels.

Explanation:

Answer:

The more protein channel or carrier a cell has, the faster will be the transport of a specific compound. In other side, lower will be the transport of the rest of compounds, such as O2, H2O.

Explanation:

A protein channel or a carrier protein acts as facilitators in the transport of compounds. The compounds who are polar can't pass easily, or can't even pass, trough the plasmatic membrane, because of it's nonpolar center. So, the cell needs to provide a way for the polar compounds who are needed inside or outside of the cell, thus we have the proteins channel or carrier. They form a polar way for the polar compounds pass into or out the cell.

However, the more proteins we have to transport, less space the membrane will have for the others compounds, because every transport protein just acts with a specific compound or others very similar to it.
