Answer:

In metaphase 1, chromosomes from the mother and father line up randomly along the middle of the cell.

Explanation:

In diploid (2n) organisms, the homologous chromosomes are the two copies of each chromosome, where one of these homologs is the chromosome from the mother, while the second one is from the father. During metaphase I, the homologous pairs of chromosomes pair together at the middle of the cell. The law of independent assortment, also known as or Mendel's Second Law, states that homologous chromosomes line up in random orientations at the metaphase plate during this period (metaphase I).

A force of 2.20 N is exerted on a 7,20 g rifle bullet. What is the bullet's acceleration? (Enter your answer in m/s^ 2 )
sweet [91]

Answer:

The answer is 306 m/s^2

Explanation:

F = m*a

We can rearrange this formula to get a = F / m.

The SI unit for mass is kilograms (kg).

The SI unit for acceleration is m/s^2.

There are 1000 grams in a kilogram.

7.20 g = 0.00720 kg

Force (2.20 N) / 0.00720 kg = 305.56 m/s^2

Accounting for Sig Figs, the answer is 306 m/s^2.

Gee, that's one fast bullet.

(30 points)the compound water is made from the gases oxygen and hydrogen how is water different from the elements that make it u
butalik [34]

The molecule of water is different from the molecules of oxygen and hydrogen in the following ways:

1. Combustion: Oxygen supports combustion, hydrogen burns in the air to form water. Water is not combustible. It rather inhibits combustion when poured over burning substances.

2. State of matter: Water is a liquid in room temperature whereas oxygen and hydrogen are gases. The polar nature of water contributes to hydrogen bonding between the hydrogen and oxygen atoms of water.

3. Density: Water is denser than both oxygen and hydrogen. Hydrogen bonding helps pack more molecules of water in less space.

4. Freezing point: Water freezes to ice at 0°C whereas oxygen freezes at -218°C and hydrogen freezes at -259°C.

What is the unresolved problem that is facing scientists on the island of Guam?
Gekata [30.6K]

Hi

Guam is an unincorporated territory of the United States which means that the area donot posses its own municipal government. This lies within the administrative and political jurisdiction of own area. However, they still are the citizens of United States.

The indigenous people of the Guam  Island are called Chamorros and mainly they speak English and  Chamorro languages. The people are US citizens.

Because of being an unincorporated territory , the citizens are facing several problems that should be resolved. Such as:

  • The social and legal rights of Indigenous people.
  • Illegal usage of drugs because there are no proper established laws.
  • Land ownership issues.
  • Unrestricted immigration in the Island because of lack of laws.
  • Domestic violence

Scientists face these issues when they want to study the life at island of Guam.

Hope it helps!

What do we call the process where part of the DNA is saved during replication?
Nataly_w [17]

Answer:

The process where part of the DNA is saved during replication is known as semi conservative replication.

Explanation:

During cell division, a cell must first replicate its DNA (Deoxyribonucleic acid).  When a cell divides into daughter cells , the DNA of the parent cell must be copied because DNA contains the genetic material of an organism. DNA replication is the process in which DNA is copied  during the cell  division cycle.  During replication, the complementary strands of the original double helix DNA are separated and one of the two strands in the original molecule is saved in the new DNA molecule. Thus the new DNA molecule is made of an original strand and a newly synthesized strand. So the DNA replication is known as semi conservative replication. Each strand of the original DNA molecule is referred as the template strand because it provides information for the production of newly synthesized strand. It takes place inside the nucleus of a cell during the s stage  of the cell cycle. During replication, helicase enzyme breaks the hydrogen bonds between the complementary bases (Adenine with Thymine, Cytosine with Guanine) and unwinds the double helix of DNA. The two separated strands create a Y-shaped replication fork and act as templates for the synthesis of new strands of DNA. Enzymes known as DNA polymerases create the new strands.
