Answer:
B
Explanation:
Mostly, terrestrial planets (which are mainly made up of rocks) are usually smaller in size and therefore have lower mass, in comparison to gas planets. An example, in our solar system, is Saturn and Jupiter are bigger than Earth, Mercury and Venus. Due to their low mass, their gravitational pull is not strong enough to retain an atmosphere of very light gas such as hydrogen and helium. These terrestial planets can retain heavier gas such as carbon dioxide and oxygen.
The terrestrial planets lack hydrogen and helium in their atmospheres because hydrogen and helium were blown away by solar wind.
The correct option is (C).
Why it is difficult for terrestrial planets to retain hydrogen and helium?Terrestrial planets have a solid planetary surface, which distinguishes them from larger gaseous worlds.
Terrestrial planets are nearest to the sun, so the temperature in these planets are high.
Due to high temperature, hydrogen, and helium gases are blown away.
Hydrogen and helium are very light gases, that's why always go upside away from surface.
Thus, option (C) solar winds blow away hydrogen and helium is correct.

Which of the following describes the role of cyclic AMP (cAMP) in hormone response? A. cAMP receives messages from mRNA to begin protein synthesis. B. cAMP opens a pore for steroid hormones to enter the nucleus. C. cAMP are molecules that bind and captures the nonsteroid hormone. D. cAMP receives a message from a nonsteroid hormone and carries the message into the cell.
Answer:
D
Explanation:
Hormones are bigger than the cell pores hence cannot pass through the cell membrane to influence biochemical processes. Therefore, hormones (such as glucagon and insulin) bind onto receptors on the cell membrane, then transmembrane proteins, such as the G-protein, change conformation activating the secondary messengers inside of the cell. Cyclic- AMP is a major secondary messenger significant in activating protein kinases.
How can sunspots affect Earth’s climate? An increase in sunspots could cause an increase in Earth’s temperature. The magnetic pull of sunspots could change the shape of Earth’s orbit. A decrease in sunspots could cause an increase in Earth’s temperature. Sunspots can contribute to the buildup of greenhouse gases.
THE ANSWER IS A
Answer:
The answer is A
Explanation:
Sunspots are storms on the sun's surface that are marked by intense magnetic activity and play host to solar flares and hot gassy ejections from the sun's corona. Scientists believe that the number of spots on the sun cycles over time, reaching a peak—the so-called Solar Maximum—every 11 years or so.
An increase in sunspots could cause an increase in Earth’s temperature, thereby affecting Earth’s climate.
What are sunspots?Sunspots are dark areas in the Sun produced by storms on its surface, where the magnetic field (magnetic pressure) is really strong.
Sunspots reach very high temperatures that range from 3,000 to 3,700 degrees (Kelvin degrees).
Sunspots can affect the Earth's climate and the magnetic field of our Earth planet.
In conclusion, an increase in sunspots could cause an increase in Earth’s temperature, thereby affecting Earth’s climate.

The feathers of a male goldfinches become brightly colored each spring. Which best describes why the color of the feathers change each year?
Answer:American Goldfinch follows this pattern. Beginning in September, and continuing for six to eight weeks, they molt all of their feathers, ending up with a completely new and pristine set of feathers (and drab colors) as they head into the winter. In the spring, as they grow new body feathers the males especially transform into bright yellow breeding plumage, but the wing and tail feathers remain from the previous fall. As these wing feathers get older the pale buff edges fade to white and disintegrate, so that by the end of the summer the wings look essentially all black. And in September another complete molt begins.
Explanation:
Final answer:
The brightening of male goldfinches' feathers each spring is due to hormonal changes, primarily an increase in testosterone, linked to the breeding season. This change signals the male's health and genetic fitness to potential mates, a phenomenon known as sexual selection.
Explanation:
The feathers of a male goldfinches become brightly colored each spring primarily due to hormonal changes related to the breeding season. As the days lengthen in spring, there is an increase in the secretion of testosterone, which triggers changes in appearance and behavior in many songbird species, including goldfinches. This hormonal surge leads to the development of brightly colored feathers, which are used to attract females. The brighter and more vivid the plumage, the more likely a male is to attract a mate, as it signals good health and genetic fitness. This is an example of sexual selection, where traits that are favorable for mating are selected for over generations.
In addition to attracting mates, the change in feather coloration can also be tied to other behaviors such as singing and territory defense, which further enhance a male's chances of reproducing. This phenomenon is not unique to goldfinches but is observed in various bird species, where males often exhibit brighter colors or more elaborate behaviors to attract females.
In your own words, justify the statement, “oceanic conditions determine human activities
Answer:
The statement "oceanic conditions determine human activities" may be interpreted in many ways.
1. Oceanic conditions determine human activities in that the moon cycle influences the tide. As the moon cycle is said to greatly influence human activity, and the tide changes as the moon does, it may also be concluded that the tides have a similar influence on human activity.
2. Weather conditions may also influence oceanic conditions.
a) Hurricanes and typhoons occur in the ocean and if they make landfall, humans are sometimes required to evacuate the location they will affect. The process of evacuation, and the reparations necessary to human civilization afterward, are both examples of oceanic conditions being influential to human activity.
b) Flooding and tsunamis may also result in evacuation, and damage to human civilization.
c) Global warming, which is resulting in the melting of the polar ice caps, contributes to rising sea levels. Rising sea levels are also oceanic conditions that may affect human civilization in the forms of flooding, erosion, and the ocean expanding, and also determine human activities.
What's the difference between EHR and EMR?
Answer:
EHR (Electronic Health Records) contains all the clinicians involved in a patient's care and all authorized clinicians involved in the patient's care can assess the information provide to the care of the patient. EHR can be shared with other health care providers (labs, specialist) and follows the patients to where they will be seen (i.e. specialist, another hospital, nursing home, or in another country)
EMR (Electronic Medical Records) is the digital version of the patient's paper chart; contains notes and information collected by the clinicians in that office, hospital, or clinic and used by providers to diagnose and treat. They are valuable than paper records because it helps providers track data over time, identify patients for preventative visits/screenings, monitor patients, and improve their overall health care.
Explanation:
Final answer:
EHR and EMR differ in scope, interoperability, and comprehensiveness in managing patient health information.
Explanation:
EHR (Electronic Health Records) and EMR (Electronic Medical Records) both are digital versions of patients' health information but with some distinct differences. EHRs focus on a broader view of a patient's health record and can be shared across different healthcare settings, while EMRs are more specific to individual healthcare providers.
One of the key differences lies in interoperability - EHRs allow for information exchange between different healthcare organizations, promoting better coordination of care, while EMRs are typically confined to a single practice.
Additionally, EHRs are designed to be comprehensive, encompassing a range of health information, whereas EMRs tend to be more clinical in nature, focusing on specific medical encounters within a provider's practice.

In a beetle species the red color is dominant over the white color. What is the genotype of any red beetle resulting from this species?
1Points
A
red and white alleles present on one chromosome
B
red and white alleles present on two chromosomes
C
a red allele present on both homologous chromosomes
D
a red allele present on at least one of two homologous chromosomes
Answer:
Option D, A red allele present on at least one of two homologous chromosomes
Explanation:
It is given that in a beetle species the red color is dominant over the white color. Thus, in order to have a offspring of red color at least one of the two homologous chromosome must have red allele.
This can be further understood from the cross below -
Suppose one of the parent is homozygous red with genotype "RR" and other parent is homozygous white with genotype "rr"
If a cross is carried out between the two parents, the following offsprings will result -
RR x rr
Rr, Rr, Rr, Rr
Since there is no co dominance, thus the dominant allele will express itself completely and hence at least one of the homologous chromosome of offspring must have red color allele.

14. As a result of the fungus infection, the change
in moth wing color distribution would most
probably occur by the
(1) production of sex cells by mitosis
(2) natural selection of favorable variations
(3) eating of pigments in fungus spores
(4) production of mutations as a result of
eating the fungus
Moth wing color distribution would likely change through natural selection of favorable variations, similar to how darker peppered moths were favored during the Industrial Revolution due to better camouflage against soot-covered trees.
Explanation:The change in moth wing color distribution as a result of a fungal infection would most likely occur due to natural selection of favorable variations. Natural selection enhances the survival and reproduction of organisms with traits well-suited to their environments. In the classic example of the peppered moth during the Industrial Revolution in England, darker moths were naturally selected because they could better camouflage against the soot-covered trees, making them less visible to predators. Directional selection occurred, shifting the population's genetic variance towards the darker phenotype. Similarly, if a fungus changes the environment or the appearance of moths, natural selection would favor the moths whose coloration allows them to best avoid predation, leading to a change in color distribution in the moth population over time.
