Could there be winds without differential heating? Using evidence from Unit 5 explain what differential heating is and whether this effects the earth’s global wind patterns.
HELPPP PLEASE SITE EVIDENCE (WILL MARK BRAINLIEST)!!!!!!!!
Differential heating is responsible for the wind patterns across the globe.
Differential heating is defined as the difference in heating of air on the land versus water. Sea breezes occur when land heats up faster than water which rises and creates a low pressure system. The high pressure air from the sea influxes is responsible for the creation of a sea breeze.
Unequal heating of the Earth's surface is responsible for the formation of large global wind patterns. Warm air rises at the equator and moves toward the poles while on the other hand, the cooler air rises at the poles and moves back toward the equator so in this way the earth’s global wind patterns occurs so we can say that differential heating is responsible for the wind patterns across the globe.

How do bogs keep themselves cool
Answer: Like humans, dogs need to keep themselves cool to protect their bodies. They do sweat, but not in the same way. They only have sweat glands only on the paw pads and nose leather. Since they are covered with fur, it is more challenging to keep their bodies cool.
After your dog runs around, you will notice that he begins to pant heavily. Dogs rely on panting to keep their bodies cool. Panting causes the evaporation of water from the nasal cavity, tongue, throat and lungs, which helps lower their body temperature.
They also experience the same dilation in blood vessels as humans, which brings blood to the surface of the skin, allowing the air in the environment to cool them.
Any dog is at risk for heat-related problems, especially in warm, humid weather. Our brachycephalic friends are at a much greater risk than their long-nosed counterparts. Large breeds with thick coats, such as Bernese Mountain dogs or Pyrenees are also more prone. Dogs with pre-existing heart conditions or respiratory issues are also more likely to be overcome by the heat.
When these dogs pant to try and cool themselves, they have to work harder to do so. This only raises their body temperature even higher, making it worse instead of better.
What would happen if cytokinesis failed?
The nucleus would never divide, and the new daughter cells would lack a
nucleus and would die.
The cell would be too big and contain more than one nuclei.
The cell would eventually split on its own.
Organisms would not produce more genetic material for each new
daughter cell.
Answer:
The nucleus would never divide, and the new daughter cells would lack a
nucleus and would die.
Explanation:
Cytokinesis is an essential process of cell division, part of the cell cycle. If cytokinesis failed, cells wouldn't be able to reproduce.

It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation.
The normal period of gestation is about 40 weeks.
The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days.
The stages of human development include, in order: zygote, blastocyst, embryo, and fetus
A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula.
Changes to the form of the embryo come from differentiation and growth.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.

What is a positive feedback mechanism?A positive feedback mechanism is a technique of the body in which the body works or secretes something to the body that is needed more in the body, and it is secreted in the body out of league and number.
Platelets are present in the blood. They are spherical and are colorless and small. They help in blood clotting when there is a cut or bleeding, it prevents loss of blood by clotting the blood.
So, in the hole of the body, there will be blood loss, and releasing more platelets would help in blood clotting.
