Answer:

Dentistry and medicine may benefit from such a material.

Explanation:

A Purdue University-led research team has uncovered the chemical components of the adhesive produced by oysters, providing information that could be useful for fisheries, boating and medicine. Dentistry and medicine may benefit from such a material.

Fourteen Grey wolves were introduced into Yellowstone in 1995. By the end of 1997, there were 100 wolves in Yellowstone, and by
Shkiper50 [21]

Answer:

d) 625 grey wolves

Explanation:

Number of grey wolves in yellowstone;

1997 = 100 wolves

2002 = 275 wolves

Between 1997 and 2002 (a five year period), number of wolves increased by; 275 - 100 = 175 wolves

Population growth rate between 1997 and 2002 = 175 wolves per 5 years

Note that the population growth continued at the same rate from 2002 to 2012 (a ten year period).

Therefore;

if; 5 years = 175 wolves

10 years = (175 × 10) / 5 =350 wolves.

therefore, number of wolves between 2002 and 2012 = 350 wolves.

Number of wolves as at 2002 = 275 wolves

total number of wolves at 2012 = 350 + 275 = 625 wolves

How an immune response stars after a macrophage attacks a pathogen
marishachu [46]
After the macrophage fails the Helper T Cell stimulates the B cells (create antibodies) if pathogen is extracellular and Cytotoxic T Cells (killer T cells, release perforin) if pathogen is intracellular. Once the pathogen is killed the B Cells create Memory B Cells and the Killer T Cells create memory T Cells.

A 6,000 kg train car is moving to the right at 10 m/s and connects to a 4,000-kg train car that wasn't moving. What is the veloc
SIZIF [17.4K]

6 m/s

This type of collision is a <u>Inelastic collision </u>

Explanation:

We begin by finding the momentum of the initial train car;

Remember that momentum is given by the formulae mass (kg) * velocity (m/s)

Therefore;

Momentum = 6000 * 10

= 60,000 kg⋅m/s

The other car has zero momentum because;

4000 * 0

= 0

When the two train cars collide, the total momentum will be;

60,000 + 0 = 60,000

Therefore to find the velocity, well use the same formulae;

p = mv  whereby;

p – momentum

m – mass

v – velocity

60,000 = (6000 + 4000) * v

v = 60,000 / 10,000

v = 6

= 6 m/s

This is an elastic collision because we are assuming that no energy is lost in the collision. Most collisions, however, are not elastic but rather inelastic. In inelastic collision some of the kinetic energy is lost to the environment in some other form of energy such as heat energy.

A calico cat has both black and orange spots, which demonstrates a codominance pattern. What would be their expected genotype?
Oksi-84 [34.3K]

Answer:

Calico is a coat color found in cats, which is caused by a SEX-LINKED, CODOMINANT allele.

Explanation:

Codominance means that neither allele can mask the expression of the other allele. An example in humans would be the ABO blood group, where alleles A and alleles B are both expressed. So if an individual inherits allele A from their mother and allele B from their father, they have blood type AB.
