The correct answer for this question is this one: 

Given that there are 30 people, then there are 60 alleles. 10 of these people are not tasters. So, there are 20 of those 60 are t alleles. So, 40 alleles are left, but of a mix of t and T. It said in the lesson text that people who can taste this have at least one dominant gene "T". So it could either be homozygous (T,T) or heterozygous (T,t or t,T). People with homozygous recessive genes (t,t) can't taste it.

torisob [31]

Answer:

the rocket average speed is 12 kilometers per second

Explanation:

Given that

The distance is 1140 km

And, the time is 95 seconds

We need to determine the average speed in kilometers per second (km/s)

So as we know that

Speed = distance ÷ time

= 1,140 km ÷ 95 seconds

= 12 kilometers per second

hence, the rocket average speed is 12 kilometers per second

If two places on the ground that are 25° 35'N and 25° 30'N are shown 8 cm a part on a given map, what is the scale of the map?​
a_sh-v [17]

Answer:

Explanation:Do you live in a city, or in a small town? Or do

you live on a farm or a ranch? Has your family

lived there a long time or a short time? How does

living where you do affect the way you live? For

example, do you need special clothes in the winter? Is your favorite food grown nearby, or is it

brought in from far away?

All these questions have to do with geography.

Geography is the study of our home—the earth—

and how our lives are affected by it. Almost every

detail of our lives is affected by geography. The

clothes we wear, the food we eat, the things we do

for fun, and the kinds of homes in which we live

are all connected to geography.
