Answer:
A.The continent on which the tropical plants lived changed latitudes over time.
Explanation:
When the Fossils of tropical plants should have found so this explained that the continent where the tropical plants lived changed latitudes over the time. hence, the option A is correct.
Where are the Fossils of tropical plants found?Mainly it should be found in the Svalbard which is situated in the Arctic Ocean. But at the same time it should be found in the Earth's polar regions.
And, it explained the continent where the tropical plants should be lived also it changed the latitudes over time.
Hence, When the Fossils of tropical plants should have found so this explained that the continent where the tropical plants lived changed latitudes over the time. hence, the option A is correct.

Explanation:
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.
what is the name given to animals that feed on plants for food?
Answer:
herbivores
Explanation:
1. Snapdragons can be red (RR), white (WW), or pink (RW). Cross a red snapdragon with a pink snapdragon. Give the genotype and phenotype percentages.
Answer:
RR (hom0zygous dominant) - 50%
RW (heterozygous) - 50%
Red flower - 50 %
Pink flower - 50%
Explanation:
To solve this problem, we need to use a Punnett square. A red snapdragon has a genotype of RR and a pink snapdragon has a genotype of RW.
R R
R RR RR
W RW RW
50% of the offspring would have the RR genotype (hom0zygous dominant) and 50% would have the RW genotype (heterozygous). The RR genotype results in a red flower, and the RW genotype results in a pink flower, so 50% of the offspring would be red and 50% would be pink.

Meiosis only occur in what type of cells?
Answer:reproductive cells
Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
what is the possible Genotypes and the Possible Phenotypes
Answer:
possible genotypes are - Rr Rr Rr Rr
Possible phenotypes - remember that R is dominant therefore all of the seeds with be round

Each element absorbs light at specific wavelengths unique to that atom. When astronomers look at an object's spectrum, they can determine its composition based on these wavelengths. The most common method astronomers use to determine the composition of stars, planets, and other objects is spectroscopy.

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.
Compare and contrast kinetic and potential energy.

How is photosynthesis and cellular similar, and how are they different?
Answer:
Photosynthesis makes the glucose that is used in cellular respiration to make ATP. While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. It is the released oxygen that is used by us and most other organisms for cellular respiration.

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
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.

He walked 5 units south and met his friend Joshua. After that, he walked 2 units east and there he bumped into his friend Ethan.
At what location on the coordinate grid did Sam meet Ethan?
OA. point (-3,5)
B. point (-1,-3)
Oc.
point (-3,-5)
O
D. point (-3,-1)
Answer:
(-1,-3) on the coordinate grid.
Explanation:
The location from where Sam started his morning walk is 3 units to the left and 2 units up from the origin. This location is indicated by the point (-3,2).
He walked 5 units south and met his friend Joshua.
So, find the point that is 5 units to the south of point (-3,2). Distances north and south on the map represent a change in the y-coordinate. Moving 5 units to the south on the map from point (-3,2) places the new location at point (-3,-3).
Sam then walked 2 units east, where he met his friend, Ethan.
So, find the point that is 2 units to the east of point (-3,-3). Distances east and west on the map represent a change in the x-coordinate. Moving 2 units to the east on the map from point (-3,-3) places the new location at point (-1,-3).
So, Sam met Ethan at the location indicated by point (-1,-3) on the coordinate grid.

Explanation:
yoo i had this question on a study island!!
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
P - Artificial active immunity
Q - Natural active immunity
Question:
In your opinion, which immunity is the best? Why?
Anyone plz help this question...?
Answer:
The correct answer would be - natural active immunity.
Explanation:
Active immunity is the immunity that includes that develops antibody by the immune system after exposure to a pathogen naturally through disease or artificially by the process of immunization. This type of immunity is a long-lasting immunity.
If the active immunity is deliberately developed by exposure of antigen to the patient is called Artificial active immunity whereas natural immunity takes place through contact with a disease-causing agent.
In my opinion, natural active immunity is best as it is a fact that natural infection almost always causes better immunity than vaccines.
