What happens to chromosomes when an ovum and a sperm meet at fertilisation

Answers

Answer: When egg and sperm cells combine in fertilizations, they merge the two sets of chromosomes, ending up with 46 chromosomes in total. The maternal chromosomes from the egg cell and the paternal chromosomes from the sperm cell pair up. The resultant cell is called a zygote. Fertilization happens when a sperm cell successfully meets an egg cell in the fallopian tube. Once fertilization takes place, this newly fertilized cell is called a zygote. From here, the zygote will move down the fallopian tube and into the uterus. The zygote then burrows into the uterus lining.

How does natural selection lead to the evolution of a species?

Answers

Answer:

One of these is natural selection, which is a process that increases the frequency of advantageous gene variants, called alleles, in a population. Natural selection can result in organisms that are more likely to survive and reproduce and may eventually lead to speciation.

Explanation:

When a species evolves, it can get more repellent and tougher to what kills them off. For exp, if a animal can’t survive due to a carried disease, it will eventually evolve to be stronger against it.

why is this conversion of energy from one molecule to another necessary for all cells?

Answers

[tex]\mathfrak{\huge{\orange{\underline{\underline{AnSwEr:-}}}}}[/tex]

Actually Welcome to the Concept of the energy conversion

=> ATP can be used to store energy for future reactions or be withdrawn to pay for reactions when energy is required by the cell.

=> When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).

Answers

Answer:

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in and out of the lungs through the trachea, bronchi, and bronchioles. Blood moves in and out of the lungs through the pulmonary arteries and veins that connect to the heart.

The circulatory and respiratory system work together to provide oxygen and remove carbondioxide gas.

How circulatory and respiratory system work together?

The circulatory and respiratory systems work together to circulate blood and oxygen throughout the body. Air moves in to bring oxygen and out of the lungs to remove carbondioxde gas from the body. Blood moves into the lungs to bring carbondioxide gas and to load oxygen with the help of pumping of heart.

So we can conclude that circulatory and respiratory system work together to provide oxygen and remove carbondioxide gas.

Santos and Lüderitz are the same distance from the equator, and both cities are near the ocean. The air temperature in Lüderitz is colder than the air temperature in Santos. What causes the air temperature in these places to be different? Explain what causes the difference as completely as you can.

Answers

Answer:

The Ocean Currents.

Explanation:

if you look at a current map, you'll see warm currents near Sanots and cold ones near Lüderitz. Therefore, the air in Sanots is a lot warmer and the air in Lüderitz is colder.

The phenomenon of the ocean current is responsible for this deviation of air temperature between two places.

What do you mean by Air temperature?

Air temperature may be defined as the temperature of the surrounding air of organisms including humans.

The ocean water captures the heat from the sunlight and increases the temperature of the ocean. This heat is then entranced through ocean circulation and increases the temperature of the air as well as the atmosphere.

The air temperature in Luderitz is colder because the ocean of this region receives less sunlight in low intensity which results in less heat captured by the ocean and makes the air a little bit colder than that of Santos oceans.

Therefore, it is well described above.
