Answer:
By convection, heat is transfered from the bottom of the water or fluid to the top in ripple current form.
By radiation, the nearby materials will also increase in temp without any material medium.
By conduction , the spoon in the liquid will be hot. Heat is transfered through metal by conduction
Answer:
D.
Explanation:
In biology, a gene is a sequence of nucleotides in DNA or RNA that codes for a molecule that has a function.
Answer: the cars run on pure solar electricity and are driven by motors so there is no use or out put of gasoline of any kind
Explanation:
Let's look at some formulas for feldspar molecules.

In each of these you should notice that besides there being 8 oxygen atoms, the total number of atoms adds up to
13. (if an element has only 1 atom the number is just left off)
Answer:
1. Please find the explanation to Part A below
2. Process 1 is meiosis while process 3 is cell division
3. Cells produced in process 1 are haploid while cells produced in process 3 are diploid
Explanation:
PART A:
The process 2 described in the attached image is called FERTILIZATION. It is the process whereby male gamete (sperm) unites with the female gamete (egg) to yield a ZYGOTE. This process of fertilization is important to sexual reproduction because it is the way the diploid state of an organism is restored after haploid gametes must have been formed via meiosis. In other words, haploid (n) sperm and egg unites during fertilization to yield a DIPLOID ZYGOTE (2n).
PART B:
- Process 1 in this attached image depicts MEIOSIS, which is the process whereby haploid daughter cells (gametes) are formed from the division of a diploid cell. Meiosis reduces the chromosome number of a cell by half.
- Process 3 is CELL DIVISION. The zygote formed from fertilization (process 2) undergoes series of cell division to produce the EMBRYO.
PART C:
The cells produced in process 1 (meiosis) are HAPLOID i.e. contains one set of chromosomes while the cells produced in process 3 (cell division) are DIPLOID i.e. contains two set of chromosomes
