Why are asteroids irregular in shape

Explain how scientists think about fitness

nikitadnepr [17]

Answer:

Scientists believe that fitness is not only the ability to have physical fitness but it also refers to the adaptations that make an organism survive in its environment.

According to biological studies, biologists believe that the ability of an organism to survive in a particular area and to pass on its characteristics to its offspring is fitness.

The health scientists define fitness as the ability of an individual to be physically fit and to move without pain.

The scientists which study psychology believe that fitness is the well functioning of a person;s body as well as his/her mind.

Approximately how many gallons of water are used per year in a typical home? 1 million gallons 500,000 gallons 150,000 gallons 1

Advocard [28]

146 gallons of water

<h2>Further explanation </h2>

The human need for water (for drinking) is 8 glasses a day or about 2 liters. 1 gallon usually contains 19-20 liters. One house usually consists of 4 people <em>(father, mother, brother, sister). </em>

If one person consumes 2 liters of water, then one house will consume about 8 liters a day.

Which will take up 2 gallons in 5 days.

1 Year = 365 days

365 days : 5 days <em>(2 gallons)</em> = 73 <em>(gallon water refill frequency) </em>

73 x 2 = 146

So, within 1 year the level of gallon water consumption in an ordinary house consumes 146 gallons of water.

That is the calculation of the use of gallons for consumption, <em>not for bathing, washing, pooping, urinating, etc. </em>

What three processes lead to variation among offspring that have the same two parents?

beks73 [17]

Explanation:

Genetic variation in offspring during sexual reproduction is caused by

crossing over
independent assortment
randomized fertilization

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells. This process is known as mitosis, and occurs in cell division and growth processes. Two new nuclei are formed, along with identical cells. These are the same as the parent cell and the chromosome number (2n) is maintained.

Conversely in meiosis, the number of chromosomes (2n) is halved through meiotic divisions, producing 4 (n) germ cells (sperm or eggs), each containing half the number of chromosomes as its parent cell.

crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.
independent assortment in metaphase I of meiosis: chromosomes align independently and genes segregate independently into new combinations ...in humans 2n, n = 23, 8 million combinations of chromosomes possible
randomized fertilization: sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes
