Answer: Plate C
Explanation: In the picture, we can observe that the northern hemisphere experiences winter, whereas the southern hemisphere experiences summer. It is because the tilt of the earth is facing away from the sun in the northern hemisphere and the tilt is facing towards the sun in the southern hemisphere.
In the winter experiencing northern hemisphere, the plates L, K and J are having night time. But plate B, C and D are having daytime.
Here, plate D is region experiencing both the effects of summer and winter as it is in the equatorial zone. So it will not be fully considered to be experiencing winter.
Therefore, the plate C is the region that experiences daytime during winter.
Answer;
-Crossing over and random independent assortment.
The two events that increase the genetic diversity of the daughter cells produced are crossing over and random independent assortment.
Explanation;
-During prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments, which resulting to recombination that creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
-Additionally, when cells divide during meiosis, homologous chromosomes are randomly distributed during anaphase I, separating and segregating independently of each other, this results in gametes having unique combinations of chromosomes.
Answer:
I) For gametes formation
II) For pollen grain formation
III) For seed formation
Explanation:
The importance of meiosis are:
- gamete formation
During meiosis, sex cells such as sperms and ova are formed in the testes and ovary respectively
- pollen grain formation
Pollen grain are formed in the anthers of flowering plants
- Seed formation
Seeds also known as ovules, are formed in the ovary of flowering plants
Answer: Most likely to narrow down soil sample matches:Soil color
Explanation:
Investigating soil characteristics like water content, age, and mineral composition, can be very important in the figuring out soil sample matches. Along with soil processes, which include carbonate makeup, chemical changes and changed organic matter; these factors can all be determined by looking at soil's most obvious physical property, color.
For instance, red or yellow soil shows the presence of iron oxides and dark colored soil is likely to contain higher amounts of organic matter (decayed vegetation and animal remains). Thus, soil from closely related sites should show matching characteristics, and color analysis allows for the full analysis of soil sample matches of the same profile.
Answer:
Presence of rare minerals or artificial debris
Explanation:
In the lesson it clearly states, "Rare minerals and rocks or artificial debris can narrow down possible soil matches." This is also in the science journal.
