Answer:

The sex chromosomes (X and Y) determine whether a cat will be male or female. Each cat has a pair of sex chromosomes with the possible combinations of XX (female) and XY (male). The X chromosome also carries the coding gene for the black and orange colors in a calico's coat.

Explanation:

Female calico cats have two X chromosomes and therefore have two chromosomes with color code. Only if the cat gets one orange-coded X and one black-coded X, will she be calico, expressing both black and orange coloration.

Because male cats have one X chromosome with code for black or orange and one Y chromosome with no color genes, they cannot technically be calico. They'll only express either black or orange, but not both.

Answer:

A = 4000 years

Explanation:

Given data:

Half life = 2000 years

Total mass = 100 g

Mass remain = 25 g

Time taken to reduces to 25 g = ?

Solution:

At time zero = 100 g

At first half life = 100 g/2 = 50 g

At 2nd half life = 50 g / 2 = 25 g

Time taken:

Half life = Time elapsed / number of half lives

2000 years = Time elapsed / 2

Time elapsed = 2000 years × 2

Time elapsed = 4000 years

Answer:

Darker coloring is currently better for the peppered moth's survival.

Explanation:

Dark coloring is currently better for the peppered moth's survival because this dark colour enable the peppered moth to hide from the birds who feeds on them. Due to industrial revolution, a black powder of smoke emitted from industries spreads on the vegetation. This black powder helps the dark peppered moth to hide from the predators so it increases the survival of peppered moth.

A strike-slip fault is a dip-slip fault in which the dip of the fault plane is vertical. Strike-slip faults result from shear stresses .

Answer:

A blood vessel is severed.

Blood and blood components leak out the breaks.

Chemicals are released from the injury site and from underlying callogen.

The smooth muscle in the vessel wall contracts near the injury point, reducing blood loss.

Fibrinogen is converted to fibrin.

The platelets become activated making them spiked and sticky.

Fibrin forms a mesh that traps more platelets and erythrocytes, producing a clot.

Explanation:

Hemostasis is the process by which the body prevents and stop blood loss through bleeding.

Hemostasis occurs in three steps:

1. Vasoconstriction: Once a blood vessel is severed or cut, the smooth muscles of the blood vessels start to constrict or get narrower around the severed vessel in order to reduce blood flow through it. This vasoconstriction occurs in response to chemicals released from the cut vessel and the underlying collagen.

2. Platelet-plug formation: the platelets become activated by a glycoprotein called Von Willebrand factor (vWF), which is found in plasma and begin to clump together sticking together. This is known as primary hemostasis.

3. Clot formation: in response to platelet-plug formation, several clotting factors are activated which eventually convert fibrinogen to fibrin. Fibrin is mesh-like and holds the platelets as well as red and white blood cells in place, thereby forming blood-clots over the wound.

Answer:

It is often said that life is “carbon-based.” This means that carbon atoms, bonded to other carbon atoms or other elements, form the fundamental components of many, if not most, of the molecules found uniquely in living things. Other elements play important roles in biological molecules, but carbon certainly qualifies as the “foundation” element for molecules in living things. It is the bonding properties of carbon atoms that are responsible for its important role.

The main cause of pollution is the burning of fuel, over-use of fertilizers and pesticides, carelessness, and the improper disposal of waste. And who does this? Not casper, not pennywise, not animals, but us humans. So we are the main reasons why pollution exist.

You can just write what causes pollution (the underlined), you dont need to write about who causes it.

Answer:

tropical, temperate, and polar

The three major climate zones are tropical, polar, and temperate.

A larger pattern, which helps one to understand weather is known as climate. The climate of the region is predicted by the average weather in the location over a long time duration. The three prime climate zones of the Earth are:

The climate region close to the equator with warm air masses is called tropical. In this climate zone, the average temperature in the coldest month is 18 degree C. This is warmer in comparison to the average temperature of the warmest month in the polar zone.

The polar climate zone is found in the North and South poles due to adjacent cold air masses. In this zone, the warmest months average is less than 10 degree C. This is lesser in comparison nto the average temperature of the coldest months in the tropical zones.

The climate zone situated between the North and South poles and the equator is the temperate zone. The average temperature of the coldest months in the temperate zone is lesser in comparison to the tropical zones, while the average temperature of the warmest months in the temperate zone is more than that of the polar zone.

Thus, the three major climate zones are tropical, polar, and temperate.
