Answer:
Thomson's experiments with cathode ray tubes showed that all atoms contain tiny negatively charged subatomic particles or electrons. Thomson proposed the plum pudding model of the atom, which had negatively-charged electrons embedded within a positively-charged "soup."

Explanation:
What is the end result of succession?
Answer:
The early ecologists who first studied succession thought of it as a predictable process in which a community always went through the same series of stages. They also thought that the end result of succession was a stable, unchanging final state called a climax community, largely determined by an area's climate.

Answer: it’s A
Explanation:
True or False. Air can exert pressure in all directions in objects.
Answer:
true
Explanation:
The pressure exerted by air on all bodies at all times in all directions is called air pressure. When air moves at high speeds, it creates a low pressure area. The air inside a balloon exerts pressure in all directions, and makes it blow up. Air opposes the motion of a moving object.
The root word -elle translates to small. Use this information to develop your own definition for organelle
Answer:
Look below
Explanation:
An organelle is a very small cellular part or structure that has a very specific job/task in the cell.
Gazelles are adapted to run very quickly over large expanses of open land because they live in areas without many
trees. They also have wide, flat teeth that are adapted to chew grasses.
Where are these organisms adapted to live?
temperate rain forests
tropical rain forests
O deserts
savannas
Answer:
Savannahs
Explanation:
Savannahs are usually large areas of open land with few trees. This area is different from deserts because they receive more rain which allows grasses to grow, unlike desserts.
what are some ways humans inadvertently influence the whether a specific species survive?
Answer:
- Overfishing affects fish and aquatic species, decreasing their numbers
- Habitat destruction affects all species within that habitat
- Deforestation
- Pollution decreases the chance of species surviving as they eat plastic and other pollutants and get extremely sick from it
- Nature reserves and green spaces increase the chances of certain species surviving more
- Gardens and hedgerows increase the likelihood of a species surviving by giving it a small habitat to grow in and provides a new environment to thrive in

b. How does weathering affect Earth's surface?
Answer:
Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.
Explanation:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.

And you 1100 KG car comes informally to a stop if the vehicle is accelerating at -1.2 mL per second which force is closest to the net force acting on the vehicle
Answer:
The net force acting on the vehicle is closest to -1,300 N
Explanation:
In the question, for the car that comes to rest uniformly, we have;
The mass of the car, m = 1,100 kg
The acceleration of the car, a = -1.2 m/s²
According to Newton's second law of motion, the force, 'F', which causes a body of a given mass, 'm', to accelerate by a magnitude, 'a', is given by the following formula;
F = m × a
Therefore, the net force acting on the vehicle, [tex]F_{NET}[/tex], is given as follows;
[tex]F_{NET}[/tex] = 1,100 kg × (-1.2 m/s²) = -1320 N ≈ -1,300 N
The net force acting on the vehicle, [tex]F_{NET}[/tex] ≈ -1,300 N

Samantha está probando la velocidad del sonido en una montaña muy fría. Mide la temperatura en -20 ° C. Calcula la velocidad del sonido con cuatro cifras significativas.
Answer:
318,6 ms-1
Explanation:
Como sabemos que la relación entre la velocidad del sonido en el aire y la temperatura viene dada por;
V = 331√T / 273
Dónde;
V = velocidad del sonido
T = temperatura en kelvin = (-20) + 273 = 253 K
V = 331√253 / 273
V = 318,6 ms-1
why is injecting an
antigen from a pathogen would help our immune
system create "memory" of the infection but not
cause the disease
Answer:
Our immune system produces antibodies.
Explanation:
Injecting an antigen from a pathogen would help our immune system memorize the infection and protect our body from causing of the disease because our immune system produces antibodies against that antigen so when the pathogen enters our body these antibodies attack on that and prevent them of causing infection in the body so that's why injecting an antigen has to be done from the childhood to prevent diseases.

Can someone help me out please?!!!!!!!!
Bleeding from artery is more dangerous than that from vein, why?
Answer:
Due to the high pressure arteries hold and it is difficult to control.
Explanation:
Consider most of the arteries (minus the pulmonary arteries) have a thicker layer (lumen) that basically resists the ejection of blood from the heart. Arteries hold oxygenated blood to the vital organs (the heart itself throught he coronary arteries, the brain that needs EXCLUSIVE oxygenated blood, and lungs). Contrasted to a bleeding vein, bleeding from an artery tends to go faster, which increases the risk of hemorrhage and death.
if you need an analogy, think of it with a hose: if you take the hose and sever it after it's pumped into the hose on ground level, but the pump is still pumping the water, it will no longer be evenly distributed and spill everywhere.

Answer:
The trilobite is the oldest.
Explanation:
In general terms (disregarding specific examples), the lower the level in the stratosphere, the older it is. In this case, the lowest level is taken by the trilobite.
Note however, that this is not always the case, especially near edges of the plates. Sometimes plates shift, which can cause certain older fossils to be moved upwards, while newer ones are shifted downward, as one plate "eats the other". Territory creations, including valleys and mountains when plates crash into each other, can also shift where a fossil is located.

Answer:
the trilobite is oldest and that's the answer

Hemophilia is a genetic blood disorder. The female parent must carry one copy of the gene for the child to inherit hemophilia. Also, males have a greater probability of getting hemophilia than females. Which type of trait is hemophilia?
Answer:
Hemophilia is a sex-linked recessive disorder. The abnormal gene responsible for hemophilia is carried on the X chromosome. Males have one X chromosome and one Y chromosome.

A group of rabbits lives in an area that normally has mild winters that are not too cold. This
winter, however, is very cold with lots of snow. Which trait would best help a rabbit survive this
environmental stress? *
(1 Point)
A. extra thick fur
B. long ears
C. dark colored fur
D. little body fat
Answer:
A. Extra thick fur
Explanation:
Because the winter is cold and little body fat and a dark colored fur will get it killed faster, but long ears can help the bunny hear the danger but I don't think there will be any predetors out in the harsh snow.
We have 2 genes here, so we are coding for 2
different traits, AKA 2 distinct and separate
phenotypes
However, both phenotypes are present in each
offspring cat.
So, for example we could have a hairy, sink-
loving cat (like one of the parents) or a
hairless, sink-hating cat (like the other
parent). What are the other possibilities for
phenotype?
Make sure to include both traits (hair/hairless
and feelings about sinks) for each possible
phenotype.
Answer:
50% hairy and love sinks
50% hairless and hate sinks

Why is vision one of the most important sense that you can have?
Answer:
Sight and vision are important because they allow us to connect with our surroundings, keep us safe, and help maintain the sharpness of our minds. Sight and vision are different entities. Sight is physical – it is a sensory experience in which light reflects off of shapes and objects and the eyes then focus this light.
