Which object would have the highest gravitational attraction?
A. compact car
B. bicycle
C. semi truck
As a spaceship travels from Earth to the moon, which value never changes?
A. velocity
B. weight
C. acceleration
D. mass
Given what we know, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would not change during its trip.
Why would the truck have the highest gravitational attraction?This has to do with how we calculate gravitational attraction. To summarize it greatly, this value is directly proportional to the mass of the object in question. The more massive the object, the more gravity it will produce. Therefore, since the semi-truck is the largest, it will have the greatest gravitational attraction.
Why does only the mass of the spaceship remain constant?This has to do with the relationship between each value and the situation described. The acceleration and velocity will change as the ship loses fuel and is affected by the gravity of the earth and moon. The weight of the ship is also affected by gravity, whilst the mass is a physical property that does not depend on any of these and therefore does not change.
Therefore, we can confirm that a semi-truck would have the highest gravitational attraction of the objects mentioned, while for the spaceship, its mass would not change during its trip.

What are muscles? How are they responsible for locomotion?
Answer:
I hope...u understand it
Explanation:
Muscle tissue is characterized by properties that allow movement. Muscle cells are excitable; they respond to a stimulus. They are contractile, meaning they can shorten and generate a pulling force. When attached between two movable objects, in other words, bones, contractions of the muscles cause the bones to move. Some muscle movement is voluntary, which means it is under conscious control. For example, a person decides to open a book and read a chapter on anatomy. Other movements are involuntary, meaning they are not under conscious control, such as the contraction of your pupil in bright light. Muscle tissue is classified into three types according to structure and function: skeletal, cardiac, and smooth
Heya!
Muscles are the group of tissues present in every eegion of the body, with one main role, to aid in locomotion (or) movement.
How are they responsible ?
These muscles are popularly classified into two - biceps and triceps. Theuly are attached to the bones by means of tendons and ligaments.
When a body, like human, moves, then these muscles give energy to the bones by supporting and covering them at 360°.
Also, these muscles are flexible.
This aids the bones by giving them a central position, thereby giving it enough space to change its position as the person moves.

For this assignment, you will develop and use a model of the Earth-Moon-Sun system to describe the cyclic patterns of lunar phases and eclipses of the Sun and moon. You also will model and illustrate how the tilted Earth rotates on its axis, causing day and night.
You will then create a multimedia presentation featuring your models.
Background Information
Earth rotates on its axis, which causes day and night. Earth also revolves around the Sun. The path Earth follows is called its orbit. It is shaped like an oval. The moon orbits Earth in the same way. It revolves around Earth and rotates on its axis in 27.3 days. Because it rotates and revolves around Earth in the same time frame, a “day” and a “year” on the moon are the same, and the same side of the moon always
faces Earth.
As Earth revolves around the Sun, the seasons change. Earth is actually closest to the Sun when the Northern Hemisphere experiences winter. The cause of the seasons is actually Earth’s tilt. Summer in the Northern Hemisphere occurs when the north is tilted toward the Sun. The Sun's rays hit Earth more directly, which heats the surface. During the Northern Hemisphere’s winter months, the north is tilted
away from the Sun. So, the Sun's rays hit Earth less directly. When the Northern Hemisphere experiences summer, the Southern Hemisphere experiences winter. When the Southern Hemisphere experiences summer, the Northern Hemisphere experiences winter.
The moon has different shapes at different times of the month that are caused by the relative positions of the moon, Earth, and the Sun. Half of the moon is almost always lit by the Sun, but since the moon revolves around Earth, we see it from different angles. The phase of the moon you see depends on how
much of the sunlit side of the moon faces Earth.
The moon’s orbit is tilted in comparison to Earth’s orbit around the sun. The moon’s axis tilts at about 5 degrees to the plane of Earth’s. Because of the tilt of both the moon and Earth, the moon does not often get in Earth’s shadow, and the moon’s shadow does not often cover Earth. A solar eclipse happens when
a new moon blocks our view of the Sun. A lunar eclipse occurs at full moon when Earth is directly between the moon and the Sun.

Answer:
A
Explanation:
Answer:
A
Explanation:
Convection currents are the result of differential heating. Warm (less dense) material rises while cool (denser) material sinks. It is this movement that creates circulation patterns known as convection currents in the atmosphere, in water, and in the mantle of Earth.

In florida, black bears are found in only a few regions. Roads and highways cross all of these regions. If new road construction continues through the regions occupied by the bears, how will black bear populations most likely be affected?.
If new road construction continues through the regions occupied by the black bears, their populations will decrease as there will be less area to find food and shelter.
The black bear population seems to be suffering from habitat fragmentation.
HABITAT FRAGMENTATIONFragmentation is the process through which an original habitat is separated into many smaller fragments isolated from each other.
Each of these fragments has now different properties and characteristics than the original habitat.
Habitat fragmentation, due to changes in land uses, is one of the most significant threats to biodiversity at a global level.
Habitat fragmentation: a threat to biodiversityHabitat fragmentation has severe rebounds on species and population viability, communities structure, and ecosystem functioning.
In a healthy community, species are connected by trophic relationships creating complex nets. Habitat fragmentation breaks these nets, separates species, and divides the continuous vegetation surface.
There is a significant change in species abundance and loss, which might rebound all along the trophic chains.
Habitat fragmentation causes an increase in the native species extinction risks through three main mechanisms,
reduction of population sizes due to habitat loss,reduction in dispersion capabilities due to the restricted areas,decrease in the species fitness.Black bearRoads and highways across the animals' habitat set limits for their movements and displacements.
The original habitat is restricted to a new smaller one.
The animal's big sizes and the new restricted areas have a negative effect on the species survival.
Among other negative effects, we can mention the followings,
There is less food availability,It becomes more difficult to find shelters,Water is contaminated,There is trash that pollutes the environment and can damage animals.The construction of a new road will cause the black bear populations to decrease as they have less area to find food and shelter.

B. RR and Rr.
What is a Dominant Allele?A dominant allele is an allele that expresses itself even in the presence of a recessive allele.
For a dominant allele to express itself, it takes only a single copy of the allele to be present in a genotype.
Thus:
(R) is said to be dominant allele over a recessive allele (r) for tongue rolling.
