A. Nutrients and Oxygen. (The blood transports oxygen from the lungs to the cells of the body, where it is needed for metabolism. ... Blood also provides the cells with nutrients, transports hormones and removes waste products, which the liver, the kidneys or the intestine, for example, then get rid of.)

Naddik [55]

Answer:

R = 16mm/y

Explanation:

Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)

R = d/t

To calculate it in millimeters per year we need to convert it:

The problem states that in 150 million years, there is a distance of 2400 km.

if 1 km ------- 1,000,000 mm

2400 km-------X = 2400,000,000 mm

If 1 million years -------1,000,000 years

150 my----X = 150,000,000 years

R = d/t

R = 2400,000,000 mm/150,000,000 y.

R = 16mm/y

What is the grizzly bear?

The grizzly bear is a North American subspecies of the brown bear. Grizzlies are typically brown, though their fur can appear to be white-tipped, or grizzled, lending them their name. Grizzly bears are protected by law in the continental United States—not in Alaska—though there have been some controversial attempts to remove those protections in recent years.

Biological hazary are natural scenarios involving disease, disability or death on a large scale among humans, animals and plants due to micro-organisms like bacteria, or virus or toxins.

The H1N1 virus (Cause 9f Swine flu) is believed to have begun its deadly journey in pigs from a small region of central Mexico in January 2009. By March, the first cases were reported in California and Texas. By June, it was in 74 countries across the globe. A year later, when the WHO declared an end to the pandemic, between 151,700 and 575,400 people had died.

A massive global vaccine effort led by the US helped end the pandemic, but the H1N1 virus is still with us. Every year it circulates as a seasonal flu, causing sickness, hospitalisation and dead

What distinguishes an amniotic egg from eggs laid by other animals, including fishes, amphibians, and invertebrates?

PIT_PIT [208]

The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage

<h3>Characteristics of an amniotic egg</h3>

Eggs laid by amniotes are different from other eggs laid by fishes, amphibians and invertebrates in that they lack a membrane and a larval stage. the shell of the amniotic egg protects the embryo in the absence of a membrane. The shell also allows for the exchange of oxygen and carbon dioxide between the the embryo and the environment.

Hence we can conclude that The difference between an amniotic egg and eggs laid by other animals is : Absence of Membrane ( amnion ) and absence of larval stage
