Which statement about meiosis is true?
O Meiosis makes two identical cells with the diploid number of chromosomes.
O Meiosis makes two different cells with the diploid number of chromosomes.
O Meiosis makes four identical cells with the haploid number of chromosomes.
O Meiosis makes four different cells with the haploid number of chromosomes.
Answer:
Meiosis makes two identical cells with the diploid number of chromosomes
Explanation:
In meiosis cell division, cells divide to form 4 different cells with haploid chromosomes. Option D is correct.
What is Meiosis?It is a type of cell division in which cell is divided to form 4 haploid daughter cells.It occurs in the germ cells of the organisms to form sperm and ova.It is completed in 2 phases, meiosis- 1 and meiosis-2. The cells produced by meiosis are genetically different from each other.Therefore, in meiosis cell division, cells divide to form 4 different cells with haploid chromosomes.

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
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

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

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.

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.
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.

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.

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.

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 are the possible consequences to an organism when the temperature becomes colder than the optimum range for a species?
Answer:
Different species and individuals have different heat ... and extreme cold and heat—influence thermal tolerance.
Explanation:
hope it helps please mark me as a brainliest please
Temperature gets closer has the temperature level falls. Lower temperature levels generally result in low enzymatic activities, hence slowing down the rate of reaction. At temperature lower than the optimum temperature level, enzyme activities will effectively cease.
An organism's optimum range of clod temperature defines the the lower level temperature boundary at which an organism can withstand the effect of cold. Hence, once these range is exceeded, enzymatic activities will stop and could lead to death of not steadied on time.Therefore, cold temperature level beyond the maximum range for a specific species could lead to an halt in different system functions and possible death.

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
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.
