<span>Organism's habitat (where a species live) can be described as all of the biotic and abiotic factors in the area where an organism lives.
b. Ecological niche (how species live) is composed of all of the physical, chemical, and biological factors that a species needs to survive, stay healthy and reproduce. The niche includes food, abiotic conditions, and behavior.</span>
Answer:
Flowers and cones have different structures. Cones when mature have a woody texture and is made up of scales while flowers have colorful petals, sepals and both male and female reproductive portions are called stamens and pistils.
Explanation:
Answer:
A cell whose genetic material isn't found in a membrane bound nucleus.
Explanation:
Answer:
43 monosaccharides will be joined together to make the complex carbohydrate.
Explanation:
The complex carbohydrates are synthesized by the joining of monosaccharide residues by glycosidic linkages.One glycosidic linkage joins two monosaccharide residues by the elimination of one molecule of water.
In other words it can be said that elimination of one water molecule joins two monosaccharides.By the same way elimination of 42 molecules of water will result in the joining of 43 monosaccaride residues.
Correct question:
if a nondisjunction occurs at anaphase I of the first meiotic division, what will the proportion of abnormal gametes (for the chromosomes involved in the nondisjunction)?
Answer:
100%
Explanation:
Nondisjunction at meiosis-I means that two homologous chromosomes of at least one homologous pair fail to separate from each other during anaphase-I. This would result in the formation of one cell with one extra chromosome and the other with one less chromosome by the end of meiosis-I. Meiosis-II in these two cells would maintain this chromosome number in the daughter cells. Therefore, out of the total four gametes formed by the end of the meiosis, two would have one extra chromosome and would be denoted as "n+1". The rest of the two gametes would have one less chromosome and would be denoted as "n-1".
