Answer:
part of the brain that controls muscles
Explanation:
It affects movement, balance, and muscle tone leading to rigidity in the joints, involuntary movements, and exaggerated reflexes.
The left hemisphere of the cerebral cortex is likely affected in an individual with cerebral palsy who experiences movement problems in their right arm and hand due to the contralateral nature of motor control. Damage to areas such as the precentral gyrus can lead to such motor impairments.
Individuals with cerebral palsy (CP) usually have movement difficulties due to brain injury sustained before, during, or shortly after birth. The brain regions responsible for the control of body movements are affected, and the symptoms can range from mild muscle weakness to severe motor disabilities. Specifically, if a person with cerebral palsy has movement problems in their right arm and hand, the area likely affected is located in the left hemisphere of the cerebral cortex.
This inference is because the motor control of each side of the body is governed by the opposite side of the brain due to the cross-wiring of the corticospinal tract. Commands for motor movement are issued by the precentral gyrus, commonly known as the primary motor cortex, which is in the left hemisphere for the control of the right side of the body in about 95% of the population. Considering the non-progressive and permanent nature of the postural and movement disorders in cerebral palsy, interventions often focus on rehabilitation to improve or maintain motor function and coordination.

Marina has three dogs. She should check them regularly for ticks to avoid contracting:
A) Dysentery
B) Yellow fever
C) Rocky Mountain spotted fever
D) Scarlet fever
Answer:
Rocky Mountain spotted fever
Explanation:
Marina should regularly check her dogs for ticks to prevent contracting Rocky Mountain spotted fever, a disease caused by Rickettsia rickettsii and transmitted by ticks like the American dog tick.
Marina has three dogs and should check them regularly for ticks to avoid contracting Rocky Mountain spotted fever (RMSF). RMSF is a potentially fatal, tickborne disease caused by the bacterium Rickettsia rickettsii. This disease is mainly transmitted through the bite of hard-bodied ticks such as the American dog tick (Dermacentor variabilis), Rocky Mountain wood tick (D. andersoni), or brown dog tick (Rhipicephalus sanguineus). Among the diseases listed: Dysentery, Yellow fever, Rocky Mountain spotted fever, and Scarlet fever, only Rocky Mountain spotted fever is transmitted by ticks. Regularly checking her dogs for ticks and removing any ticks found can help prevent the spread of this disease.
why should/shouldn't Pluto be reclassified as a planet?
Answer:
(This could be opinion based, but ok.)
Explanation:
should:Pluto was known as a planet for 75 years. This means that most people already knew it as a planet, and would be extremely confused. All of the books about planets would be inaccurate and changed. Not all people can access brand new books, leading to inaccurate information.
shouldn't: The same reason that it was unclassified as a planet. It does not adhere to all of the rules of being a planet. It is not completely round and does not have a round orbit around the sun. Pluto does not have every requirement to be a real planet, and therefor, it would be incorrect to have it classified wrongly.

Which condition causes storms to occur?
A. freezing of water droplets
B. sudden change in air pressure
C. condensation of water vapor
D. rapid heating of upper atmosphere
B. A sudden change in air pressure is a key condition that causes storms to occur.
Why storm forms?Storms form when there is a significant difference in air pressure between two areas. This difference creates a pressure gradient, which causes air to move from high pressure to low pressure in an attempt to balance the pressure. When air moves, it rises, cools, and condenses into clouds.
If the difference in air pressure becomes large enough, the rising air can create strong winds and precipitation, resulting in a storm. So, a sudden change in air pressure is one of the essential conditions for the formation of storms.

1. What happens to organisms that have adaptations that longer work for their environment?
Answer:
There's two possibilities, either nothing happens, or they are slowly eliminated from the population.
Explanation:
Some adaptations are no longer useful, like wisdom teeth for us humans or hip bones in whales. Whales definitely don't need hip bones, but having them also doesn't really hurt their chances of survival. In these cases it doesn't matter, so the individuals remain in the population.
If the organism's chance of survival is decreased due to its adaptation no longer working, then it will be eliminated from the population through natural selection. For example, if an individual's camouflage stops working, they will be less likely to survive and reproduce.

Answer:
The last one if there are multiple answers please tell me.
Explanation:
just when with the one i knew in heart
The reappearance of recessive traits (red flowers and round pollen) in the F2 generation of a dihybrid cross is explained by Mendel's Law of Independent Assortment, which states that genes on different chromosomes assort independently during gamete formation. When members of the F1 generation cross-pollinate, recombination of alleles can result in the re-expression of the recessive traits in the F2 generation.
Explanation:Your observation of red flowers and round pollen in the F2 generation of a dihybrid cross in pea plants is possible because these traits are on different chromosomes. If two genes are located on separate chromosomes, they will assort independently during gamete formation. In a dihybrid cross involving two traits, the different combinations of alleles may result in the re-expresssion of recessive traits in the F2 generation. This is known Mendel's Law of Independent Assortment.
To illustrate, consider that a parental generation plant with dominant alleles for both traits (i.e., purple flowers and elongated pollen) is crossed with a plant having recessive alleles (i.e., red flowers and round pollen). In this case, the F1 generation will all exhibit the dominant traits because dominance masks the effect of recessive alleles. However, when the F1 generation cross-pollinates, the F2 offspring can include plants with the recessive traits due to recombination of alleles.

calories are converted to biomass. In other words:
The subject of this question is the conversion of calories to biomass in a raccoon's diet. This process is known as energy transfer or energy flow in an ecosystem.
Explanation:In biology, the subject of this question is the conversion of calories to biomass in a raccoon's diet. This process is known as energy transfer or energy flow in an ecosystem.
Calories are a unit of energy, and when a raccoon consumes food, it uses some of that energy for its own metabolic processes and converts the remaining energy into biomass, which is the living tissue of the raccoon's body.
In this case, if the raccoon consumes 500 calories and 50 calories are converted to biomass, the remaining 450 calories are used by the raccoon for its bodily functions.

#SPJ3
According to the question, out of the 500 calories consumed by the raccoon, only 50 are converted into biomass. In simpler terms, for every 500 calories of food it eats, the raccoon uses 50 calories to build up its body mass.
When the raccoon consumes 500 calories of food, it undergoes various metabolic processes to utilize this energy. Out of these 500 calories, only 50 calories are converted into biomass. This conversion involves synthesizing new molecules and tissues, such as muscle, fat, and organs, contributing to the raccoon's growth and maintenance.Metabolic rate is the amount of energy expended by an animal over a specific time. In the case of the raccoon, only a small portion of the consumed calories is converted into biomass. The remaining 450 calories are likely expended as energy to power the raccoon's daily activities, including locomotion, thermoregulation, and cellular functions like respiration and digestion. These calories are transformed into kinetic energy, heat, and other forms of metabolic energy to sustain the raccoon's life processesWhich scientist and atomic model are correctly matched?

Give examples of the physical components of an ecosystems that can change populations.
Final answer:
Physical components of an ecosystem, such as catastrophic events, forest structures, and geological processes, can significantly alter populations and lead to processes like ecological succession. The study of acorn production illustrates how food resource availability can fluctuate population dynamics. Understanding how humans impact these ecosystems is critical for assessing biodiversity conservation.
Explanation:
The physical components of an ecosystem can significantly influence populations within it. Examples that can change populations include catastrophic events such as floods, fires, and volcanic eruptions. These events can lead to a long process called ecological succession, where the ecosystem gradually recovers and reestablishes itself through a succession of species.
Additionally, at both local and broader scales, biological communities can also alter the physical environment. For instance, forests affect wind speed, soil chemistry, and light penetration. A study on acorn production demonstrated how the populations of small mammals and ground-nesting birds fluctuate with the available food resources. Identifying various ecosystems such as forests, wetlands, and Garry oak meadows helps to understand the nuanced interactions of organisms and the environment, especially when discussing how humans impact ecosystems.
Chapter 4 will delve into how such environmental changes influence population dynamics, highlighting the continuous nature of evolution and species interaction shaped by these changes. From a broader perspective, geological processes such as continental drift and meteor impacts lead to the loss and creation of ecological niches, indicating the deep interconnection between physical changes and population shifts.

B.The birthrate is higher than the death rate
C.It has reached its carrying capacity
D.The population is decreasing
It’s birthrate is higher than its death rate
Natality, mortality, and growth in populations that exhibit a logistic growth model depend on the density. Option B.The birthrate is higher than the death rate
What is logistoc growth?
Populations exhibiting a logistic growth model depend on density.
Natality and mortality depend on the population size, meaning that there is no independence between population growth and population density.
When a population grows in a limited space, density rises gradually and eventually affects the multiplication rate. The population per capita growth rate decreases as population size increases. The population reaches a maximum point known as the carrying capacity, K.
The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density (for example, competition) or might be density-independent.
What is carrying capacity?Carrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
• If the population size, N, is inferior to K ⇒ the population still grows.
• When N approximates to K, the population's growth speed decreases.
• When N=K, the population reaches equilibrium,
• When N is superior to K (N>K), the population must decrease in size because there are not enough resources to maintain that size.
In the exposed example, option B best describes the population at point B. The birth rate is higher than the death rate. At this point the population is experiencing exponential increase in size.

a student builds an model of her bedroom. the scale is 1:25 in the scale model, the students bed is 3 inches long how long is her actual bed ?
The size of actual bed is 75 inches
Explanation:
Scale refers to the ratio of the original dimension to the dimension on paper (miniaturised dimension). Since it is a ratio, it has no dimension.
Scale= original dimension/miniaturised dimension
Given that scale is 1:25
It means that every 1 inch on paper would correspond to 25 inches in reality.
The length of the model bed= 3 inches
Hence, the length of the original bed is 25*3 = 75 inches
∴ Length of the actual bed of the student is 75 inches.
By definition of scale, the length of the actual bed of the student is 75 inches.
In first place, you have to know that the scale is the relationship that exists between the magnitudes of a drawing and the actual dimensions.
That is, the scale is defined by two numbers that determine the relationship between the drawing and reality.
The first number of the proportion or relationship refers to the drawing on paper, while the second number of the proportion refers to the reality of the object (actual dimensions). This is, Scale = Drawing: Reality or [tex]scale=\frac{drawing}{scale}[/tex]
The scales can be:
Reduction scale: used when the size of the object is larger than the size of the sheet of paper. Magnification scale: used to represent small objects. Natural scale: it is used to represent objects with a drawing the same size as reality.In this case, you know that:
Scale= 1:25Drawing= 3 inchesReality= ?Replacing in the definition of scale:
1:25= 3 inches: reality
or
[tex]\frac{1}{25} =\frac{3 inches}{reality}[/tex]
Solving:
reality= 3 inches× 25
reality= 75 inches
In summary, the length of the actual bed of the student is 75 inches.
