Answer:

Explanation:

Diagram included below.

1.) 4 chromosomes. Daughter cells are not identical due to recombination (i.e. crossing over).

1.) 2n=4

2.) Cells produced by meiosis are haploid. With just one chromatid.

Explain: Meiosis I separation of homologous chromosomes but sister chromatids stay together. Meiosis II sister chromatids separate, making haploid cells with non duplicated chromosomes.

3.) Germ cells have 46 chromosomes. Gametes have 23.

4.) Meiosis occurs in testes for men and ovaries for women. Mitosis occurs everywhere, basically any cell that isn't a reproductive cell.

5.) Recombination, genetic information is randomly shuffled. Events like crossing and the random orientation of homologue pairs make the possibilities endless. Remember sperm only gets half of the man's DNA, which half is random.

6.) After fertilization you get chromosomes from both mom and dad. The two haploid cells fuse and make a diploid cell.

What is the maintenance of a fairly constant internal environment

Sladkaya [172]

Answer: Maintainance of constant internal environment is carried out in a process called Homeostasis.

Explanation:

Maintainance can of several types such as pH, temperature, and other substances such as Concentration of Ammonia in body. These all should maintain at constantly for stability in body. The maintenance of temperature is called thermo regulation.

I WILL GIVE THE BRAINLIEST AND 20 PTS!

cluponka [151]

Answer: 5(x +1.5)^2

10(x +1)^2

1/4(x +2)^2

3(x +5/6)^2

Explanation: When your desired form is expanded, it becomes ...

a(x +b)^2 = a(x^2 +2bx +b^2) = ax^2 +2abx +ab^2

This tells you the overall factor (a) is the leading coefficient of the given trinomial. Factoring that out, you can find b as the root of the remaining constant.

a) 5x^2 +15x +11.25 = 5(x^2 +3x +2.25) = 5(x +1.5)^2

b) 10x^2 +20x +10 = 10(x^2 +2x +1) = 10(x +1)^2

c) 1/4x^2 +x +1 = 1/4(x^2 +4x +4) = 1/4(x +2)^2

d) 3x^2 +5x +25/12 = 3(x^2 +5/3x +25/36) = 3(x +5/6)^2

What are the properties of clay, and what are the properties & structure of loam soils.

pantera1 [17]

Answer:These properties include: cation exchange capabilities, plastic behaviour when wet, catalytic abilities, swelling behaviour, and low permeability. (clay)

f sand (particle size > 63 micrometres (0.0025 in)), silt (particle size > 2 micrometres (7.9×10−5 in)), and a smaller amount of clay (particle size < 2 micrometres (7.9×10−5 in)). By weight, its mineral composition is about 40–40–20% concentration of sand–silt–clay, respectively. (Soil)
