Answer:

occurs in metaphase I - is random chromosome alignment resulting in variation.

occurs during sexual reproduction - fuses gametes to form offspring with genes from each parent

occurs in prophase I - exchanges genetic information between non-sister chromatids

Metaphase I is a stage of meiosis I during which chromosomes are randomly aligned at the metaphase plate. The chromosomes are randomly distributed into two daughter cells after meiosis I. Random segregation of chromosomes adds genetic variation in a population.

Sexual reproduction involves the formation and fusion of gametes. Each gamete is contributed by each parent. The fusion of these gametes results in the formation of a new combination of genes which are different from either parent.

Prophase I is the first stage of meiosis I during which the event of crossing over takes place. Crossing refers to the exchange of genetic material between non-sister chromatids of homologous chromosomes.

vova2212 [387]
Last night Jasmine and Jay amount combined is $150+$130=$280
amount donated to charity is 1/4 of $280= $70
amount spent at an amusement park is` 40/100 x $210= $84
the remaining money = 280- (70+84)= $126

35% of their original amount is 35/100x$280=$98

so Jay's claim is not correct because the remaining money is $126 and not $98 as she Jay claims.

Llana [10]

Autosomal dominant condition occurs when alleles of genes present on chromosomes in the autosomes (somatic) mask the effect of the other allele.

They can produce a light brown kid and the chances of producing this is 50%.

  • Light brown color is dominant to black. A light brown male is mated to a black female, producing a black kid.
  • For the two to produce a black kid which is in the recessive condition, the male has to be heterozygous for the condition (Bb).

Let light brown be (BB or Bb)   and black be (bb)

Parents :                   B b     x      b b

Offspring genotype:      Bb      bb

Ratio:                               1    :     1  (50%)

makvit [3.9K]

Answer:

The correct answer is - both pathways glycolysis pathway and gluconeogenesis pathway.

Explanation:

The enzyme triose phosphate isomerase includes the Glyceraldehyde 3 P dehydrogenase. It is one of the enzymes used in glycolysis as well as gluconeogenesis. These enzymes catalyze the conversion of glyceraldehyde to 1,3 bis phosphoglycerate.

Thus, the correct answer is - both pathways glycolysis pathway and gluconeogenesis pathway.

SCIENCE QUESTION
alexandr1967 [171]

Answer:

Animal cells have ribosomes for protein synthesis, unlike plants which use chloroplasts.

Explanation:

Animal cells do not have chloroplasts. Chloroplasts work to convert light energy of the Sun into sugars that can be used by cells. The entire process is called photosynthesis and it all depends on the little green chlorophyll molecules in each chloroplast. Plants are the basis of all life on Earth.
