Answer: The bladders hold lots of air.

Answer: It is the cell membrane will change and unsaturated fatty acids replace saturated.

Explanation:

Because unsaturated fatty acids have a kink, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

Cell membranes are composed of a lipid bilayer, which is made up of two layers of phospholipid molecules and consists of lipids such as saturated and unsaturated fatty acids that differ in their chemical structure, Saturated fatty acids have no double bonds between the carbon atoms in their hydrocarbon chains, while unsaturated fatty acids have one or more double bonds that provide fluidity to the plasma membrane.

Hence, substituting unsaturated fatty acids for saturated fatty acids in the cell membrane of winter wheat is a suitable adaptation for the increased fluidity present in Option A.

A 60,000-gram human at rest generates approximately 100 watts from metabolic heat.

This is because the average human at rest has a basal metabolic rate of about 1.2 kcal/min or 70 kcal/hr. Since 1 kcal is equivalent to 4.184 watts, we can calculate the amount of watts generated from metabolic heat by multiplying the basal metabolic rate by 4.184.

70 kcal/hr * 4.184 watts/kcal = 292.88 watts/hr

To get the number of watts generated per minute, we can divide this number by 60:

292.88 watts/hr / 60 min/hr = 4.88 watts/min

And to get the number of watts generated per second, we can divide this number by 60 again:

4.88 watts/min / 60 sec/min = 0.081 watts/sec

Since there are 1000 watts in a kilowatt, we can multiply this number by 1000 to get the amount of watts generated per second:

0.081 watts/sec * 1000 = 81 watts/sec

Therefore, a 60,000-gram human at rest generates approximately 100 watts from metabolic heat.

The five evidences that support the theory of evolution are: Fossils, Anatomy, Embryology, Molecular Biology (or Biochemistry), and Biogeography.

Fossils show the physical change in a species over time, suggesting evidence for evolution. For an example, we can trace the origins of dolphins and whales all the way to a four-legged, dog-like hoofed mammal from about 50 mya. These mammals were fish eaters and so decided to spend a lot of time in the water. In fact, they spent so much time in the water, that in a few million years, they evolved a longer body and webbed feet. Then another few million years passed and they swapped their webbed feet for flippers and swapped their tail of a fin. Eventually, we get a fish-like mammal that once walked on land.

For anatomy, or structures, there's three types of structure comparisons: Homologous structures, Vestigial structures, and Analogous structures (or Convergent Evolution). Homologous structures show similarities between the structures between species, but serve different purposes. For an example, all mammals share common features within their arms, such as having 5 fingers. However, they serve different purposes, from whale fins for swimming, to bat wings for flying, to human hands for grabbing and for using tools.

Vestigial structures were structures that once served a purpose and have been reduced in size/power to the point where it's useless. For an example, large theropods such as the T. Rex spent so much time evolving more jaw muscles and biting power, that they sacrificed their arm muscles for such power. This explains why their arms were so short.

Another example would be ratites, flightless birds such as ostriches, emus, and cassowaries (penguins and kakapos are from a different group). They spent so much time evolving powerful legs as well as evolving in size, that there was no need to fly when they could just run with their improved legs. And also the fact that they're too heavy to even fly anyways.

Analogous structures is the similar functions of structures between species, but have separately evolved these functions. For an example, the wings from insects, birds, bats, and pterosaurs are very similar in shape and can be used to fly, but they've evolved separately. For an example, birds use feathers to fly while bats and pterosaurs use/used (pterosaurs are extinct) membrane between their bones to fly. Although they do have strikingly similar evolutionary histories, with their ancestors starting off as tree dwellers, they've evolved their flight abilities separately during different earth periods.

Embryology is evidence for evolution by using embryos from different species to suggest a common ancestor. For an example, we can prove that we're more related to whales than to fish by using embryos. The fish embryo will evolve gills while the embryos of humans and whales will not, since we do not breath by extracting oxygen from water.

Molecular biology is a more recent way of providing evidence for evolution. By taking the DNA from cells from different species, we can get an estimate of how related one species is to another. The more similar amino acid sequences are between species, the more recent their common ancestor is. For an example, by comparing amino acid sequences between humans and chimpanzees, we get an estimated amount that we once shared a common ancestor seven million years ago. Without molecular biology, we would still be digging for fossils to find that number.

Biogeography is the geographic distribution of species on earth that can be explained by evolution. For an example, we can tell that Australia separated first from Pangea rather than Asia or North America since Australia doesn't have bears while the Asia and North America do, with China having pandas and North America having brown and black bears. And also with the fact that Australia is the only continent with monotremes (egg-laying mammals like the platypus).

Similar to biogeography, there's also direct observation, which is evolution that has happened in our own eyes. An example would be the underground London mosquito. Mosquitoes usually target birds like pigeons. But after an underground tunnel was built in London, some mosquitoes managed to get inside and instead of birds, they targeted, mice, rats, and of course, humans. After only a few hundred years, a mosquito from the underground tried to mate with another mosquito from land and they could not, simply because they were different species. This shows that their new choice of feeding on mammalian blood has actually altered their DNA and created a new species, during the existence of humanity!

The stage of the growth curve where the bacteria are producing molecules necessary for cell division, but not undergoing cell division is called the lag phase.

The lag phase is a time of adaptation during which the bacteria are becoming used to their new surroundings. Depending on how different the current conditions are from the ones the bacteria originated in as well as the state of the bacterial cells themselves, the length of the lag phase can range significantly. The four phases of a bacterial growth cycle are lag, exponential (log), stationary, and death. The bacterial growth curve shows the evolution of a bacterial population's live cell count over time. The development curve goes through four distinct phases: lag, exponential (log), stagnant, and death.

An ecosystem that has experienced a disruptive event, such as a volcanic eruption, will take time to recover from the effects of the disruption. The recovery process of an ecosystem is a complex, interconnected process between the biotic and abiotic components of a system. The recovery process that follows a disturbance varies depending on the type of disruption and the environment in which it occurs.

When a volcanic eruption occurs, it can release a great deal of ash and debris into the environment, and the effects can be devastating. The ash and debris can severely damage the terrestrial and aquatic ecosystems in the surrounding area, resulting in a loss of habitat, food sources, and other important resources. Additionally, the ash and debris can block sunlight and reduce photosynthesis, which can lead to a decrease in plant growth and a disruption of the food web.

Cardiac conduction system structures controls cardiac muscle contraction.The correct answer is D)

The cardiac conduction system is responsible for controlling the contraction of cardiac muscle. It consists of specialized cells that generate and transmit electrical impulses throughout the heart, coordinating its rhythmic contractions.

The main components of the cardiac conduction system include the sinoatrial (SA) node, atrioventricular (AV) node, bundle of His, bundle branches, and Purkinje fibers.

The SA node, located in the right atrium, acts as the natural pacemaker of the heart, initiating the electrical signals that trigger each heartbeat. The electrical impulses then pass through the AV node, bundle of His, bundle branches, and Purkinje fibers, causing coordinated contractions of the atria and ventricles.

genues are most important in school

Answer:

Advertise or tell everyone near about the country.

Explanation:

In quantitative genetics, a phenotypic value can be expressed as the sum of two components: genotypic value and environmental deviation. Option D is correct.

Genotypic value refers to the contribution of an individual's genetic makeup to the observed phenotype. It represents the average effect of the individual's alleles on the phenotype in a given environment. Genotypic value is influenced by additive genetic effects and can be passed on to offspring through inheritance.

On the other hand, environmental deviation refers to the influence of non-genetic factors on the phenotype. These factors can include environmental conditions, such as nutrition, temperature, or social interactions, that can impact the expression of genetic potential. Environmental deviation accounts for the variation in phenotypic values that is not explained by genetic factors alone.

By considering both genotypic value and environmental deviation, quantitative genetics provides a framework for understanding the complex interplay between genetic and environmental factors in determining phenotypic variation in traits. Option D is correct.
